Ancient historical texts describe the presence of aortic pathology conditions, although the surgical treatment of thoracic aortic disease remained insurmountable until the 19th century. Surgical treatment of thoracic aortic disease then progressed along with advances in surgical technique, conduit production, cardiopulmonary bypass, and endovascular technology. Despite radical advances in aortic surgery, principles established by surgical pioneers of the 19th century hold firm to this day. Copyright © 2017 Elsevier Inc. All rights reserved.

Thoracic surgical practice has evolved from the innovations of its pioneers. Beginning with the stethoscope discovered by Laënnec with his system of auscultation, to the tools we use in the dissection and control of the hilum of the lung for resection, our practice of thoracic surgery has been entwined with the development of instruments and instrumentation. The development of strategies to prevent death from the open pneumothorax began with manual control of the mediastinum and progressed through differential pressure to, finally, the technique of intubation and the methods of positive-pressure and insufflation anesthesia. The instruments we place in our hands are not enough to define our art. Entry into the chest would not be possible without the use of rib retractors, rib shears, and even periosteal elevators. Finally, to the present day of minimally invasive techniques and the application of thoracoscopy for therapeutic purposes, we find the efforts of our predecessors well developed. For the progression from the fear of the open pneumothorax to the present-day state of the ease of thoracotomy for lung resection we are indebted to those who gave so much of their time and, for some, their lives to death from tuberculosis, to allow the advancement of our practice of surgery. These great people should be remembered not only for their acceptance of novel ideas but also, more importantly, for their lack of fear of testing them.

Surgical site infection is a serious and significant complication after spinal surgery and is associated with high morbidity rates, high healthcare costs and poor patient outcomes. Accurate identification of risk factors is essential for developing strategies to prevent devastating infections. The purpose of this study was to identify independent risk factors for surgical site infection among posterior thoracic and/or lumbar spinal surgery in adult patients using a prospective multicenter surveillance research method. From July 2010 to June 2012, we performed a prospective surveillance study in adult patients who had developed surgical site infection after undergoing thoracic and/or lumbar posterior spinal surgery at 11 participating hospitals. Detailed preoperative and operative patient characteristics were prospectively recorded using a standardized data collection format. Surgical site infection was based on the definition established by the Centers for Disease Control and Prevention. A total of 2,736 consecutive adult patients were enrolled, of which 24 (0.9%) developed postoperative deep surgical site infection. Multivariate regression analysis indicated four independent risk factors. Preoperative steroid therapy (P = 0.001), spinal trauma (P = 0.048) and gender (male) (P = 0.02) were statistically significant independent patient-related risk factors, whereas an operating time ≥3 h (P operating time ≥3 h were independent risk factors for deep surgical site infection after thoracic and/or lumbar spinal surgery in adult patients. Identification of these risk factors can be used to develop protocols aimed at decreasing the risk of surgical site infection.

Moral virtues are the complement to ethical principles. They constitute the elements of character that drive habits and daily routines. Certain virtues are especially important in surgery, shaping surgical practice even when no big decisions are at hand. Eight virtues are described and the work they do is explored: trustworthiness, equanimity, empathy, advocacy, compassion, courage, humility, and hope.

Objective: the aim of this study was to analyze chest CT scans of patients with thoracic textiloma. Methods: this was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. Results: the majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). Conclusions: it is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

2013-01-01

Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. PMID:24455232

During the period between January 1996 and July 1998 in our department 1920 patients were operated on account of heart disease from median sternotomy. In 17 patients, i.e. in 0.9% during the early postoperative period the surgical wound disintegrated incl. dehiscence of the sternum and the development of postoperative mediastinitis. In 14 of these patients the authors reconstructed the defect of the thoracic wall by their own modification of Jurkiewicz plastic operation using the pectoral muscles. One patient from this group died, in the remaining 13 patients the wound healed without deformity of the chest and without signs of instability, without restriction of movement and function.

Retrospective analysis of a prospectively collected, consecutive, nonrandomized series of patients. To assess the surgical outcomes of the simultaneous double-rod rotation technique for treating Lenke 1 thoracic adolescent idiopathic scoliosis (AIS). With the increasing popularity of segmental pedicle screw spinal reconstruction for treating AIS, concerns regarding the limited ability to correct hypokyphosis have also increased. A consecutive series of 32 patients with Lenke 1 main thoracic AIS treated with the simultaneous double-rod rotation technique at our institution was included. Outcome measures included patient demographics, radiographical measurements, and Scoliosis Research Society questionnaire scores. All 32 patients were followed up for a minimum of 2 years (average, 3.6 yr). The average main thoracic Cobb angle correction rate and the correction loss at the final follow-up were 67.8% and 3.3°, respectively. The average preoperative thoracic kyphosis (T5-T12) was 11.9°, which improved significantly to 20.5° (P correction of the main thoracic curve while maintaining sagittal profiles and correcting coronal and axial deformities. 4.

Hawasli, Ammar H; Ray, Wilson Z; Wright, Neill M

2014-09-01

Idiopathic spinal cord herniation (ISCH) is an uncommon condition located predominantly in the thoracic spine and often associated with a remote history of a major traumatic injury. ISCH has an incompletely described presentation and unknown etiology. There is no consensus on the treatment algorithm and surgical technique, and there are few data on clinical outcomes. In this case series and technical report, we describe the atypical myelopathy presentation, remote history of traumatic injury, radiographic progression, treatment, and outcomes of 5 patients treated at Washington University for symptomatic ISCH. A video showing surgical repair is presented. In contrast to classic compressive myelopathy symptomatology, ISCH patients presented with an atypical myelopathy, characterized by asymmetric motor and sensory deficits and early-onset urinary incontinence. Clinical deterioration correlated with progressive spinal cord displacement and herniation observed on yearly spinal imaging in a patient imaged serially because of multiple sclerosis. Finally, compared with compressive myelopathy in the thoracic spine, surgical treatment of ISCH led to rapid improvement despite a long duration of symptoms. Symptomatic ISCH presents with atypical myelopathy and slow temporal progression and can be successfully managed with surgical repair.

Retrospective study. To report on neuromuscular patients with preserved walking ability, but forward bending of the body due to thoracic lordosis, and to suggest thoracic lordosis correction as the surgical treatment. It is an established fact that lumbar lordosis or pelvic parameter is directly related to thoracic sagittal balance. However, the reverse relationship has not been fully defined yet. Loss of thoracic kyphosis results in positive sagittal balance, which causes walking difficulty. Neuromuscular patients with thoracic lordosis have not been reported yet, and there have been no reports on their surgical treatments. This study analyzed 8 patients treated with thoracic lordosis correction surgery. Every patient was diagnosed with muscular dystrophy. In thoracic lordosis correction surgery, anterior release was performed in the first stage and posterior segmental instrumentation was performed in the second stage. Radiographic parameters were compared and walking ability was evaluated with gait analysis. All patients were classified according to the modified Rancho Los Amigos Hospital system preoperatively and 2 years postoperatively to evaluate functional ability. The average follow-up period was 2.9 years. Before surgery, the mean thoracic sagittal alignment was -2.1-degree lordosis, the mean Cobb angle and sacral slope increased to 36.3 and 56.6 degrees, respectively. The anterior pelvic tilt in gait analysis was 29.3 degrees. At last follow-up after surgery, the mean thoracic sagittal alignment changed to 12.6-degree kyphosis, and the Cobb angle and sacral slope decreased to 18.9 and 39.5 degrees, respectively. Lumbar lordosis and the sacral slope showed significant positive correlation (Plordosis showed a significant correlation to the preoperative flexibility of the major curve (P=0.028). The anterior pelvic tilt in gait analysis improved to 15.4 degrees. The functional ability improved in 2 (50%) of 4 patients in class 2 and maintained in remaining 6

The Rush Department of Cardiovascular and Thoracic Surgery received certification by the American Board of Thoracic Surgery (ABTS) to train thoracic surgical residents in 1962. The outstanding clinical faculty, with nationally recognized technical expertise, was eager to provide resident education. The hallmark of the program has been clinical excellence, dedication to patient care, and outstanding results in complex cardiac, vascular, and general thoracic surgical procedures. A strong commitment to resident education has been carried to the present time. Development of the sternotomy incision, thoracic and abdominal aneurysm repair, carotid endarterectomy, along with valve replacement, have been the hallmark of the section of cardiovascular surgery. Innovation in bronchoplastic lung resection, aggressive approach to thoracic malignancy, and segmental resection for lung cancer identify the section of general thoracic surgery. A total of 131 thoracic residents have been trained by the Rush Thoracic Surgery program, and many achieved their vascular certificate, as well. Their training has been vigorous and, at times, difficult. They carry the Rush thoracic surgical commitment of excellence in clinical surgery and patient care throughout the country, both in practice groups and academic centers.

Surgical site infection (SSI) is considered to be a priority in infection control. The objective of this study is the analysis of results of active targeted surveillance conducted over a two-year period in the Department of Thoracic Surgery at the Pulmonology and Thoracic Surgery Center in Bystra, in southern Poland. The retrospective analysis was carried out on the basis of results of active monitoring of SSI in the 45-bed Department of Thoracic Surgery at the Pulmonology and Thoracic Surgery Center in Bystra between April 1, 2014 and April 30, 2016. Surgical site infections were identified based on the definitions of the European Centre for Disease Prevention and Control (ECDC) taking into account the time of symptom onset, specifically, whether the symptoms occurred within 30 d after the surgical procedure. Detection of SSI relied on daily inspection of incisions by a trained nurse, analysis of medical and nursing entries in the computer system, and analysis of all results of microbiologic tests taken in the unit and in the operating room. In the study period, data were collected regarding 1,387 treatment procedures meeting the registration criteria. Forty cases of SSI were detected yielding an incidence rate of 3%. Most cases (55%) were found in the course of hospitalization and 45% were detected after the patient's discharge. The SSIs were classified as follows: superficial, 37.5%; deep infections, 7.5%; and organ/space infection, 55%. Among patients who were diagnosed with SSI, most were male (77.5%). For patients with an American Society of Anesthesiologists (ASA) score I-II the incidence rate was 2%; ASA score III or more, 3.7%. The incidence rate varied from 0.3% in clean surgical site to 6.5% in clean-contaminated site. The study validated the usefulness of targeted surveillance in monitoring SSIs in patients hospitalized in thoracic surgery departments. Surgical site infection surveillance identified areas of care requiring modifications, namely

Robotic thoracic surgery: The state of the art

Minimally invasive thoracic surgery has come a long way. It has rapidly progressed to complex procedures such as lobectomy, pneumonectomy, esophagectomy, and resection of mediastinal tumors. Video-assisted thoracic surgery (VATS) offered perceptible benefits over thoracotomy in terms of less postoperative pain and narcotic utilization, shorter ICU and hospital stay, decreased incidence of postoperative complications combined with quicker return to work, and better cosmesis. However, despite its obvious advantages, the General Thoracic Surgical Community has been relatively slow in adapting VATS more widely. The introduction of da Vinci surgical system has helped overcome certain inherent limitations of VATS such as two-dimensional (2D) vision and counter intuitive movement using long rigid instruments allowing thoracic surgeons to perform a plethora of minimally invasive thoracic procedures more efficiently. Although the cumulative experience worldwide is still limited and evolving, Robotic Thoracic Surgery is an evolution over VATS. There is however a lot of concern among established high-volume VATS centers regarding the superiority of the robotic technique. We have over 7 years experience and believe that any new technology designed to make minimal invasive surgery easier and more comfortable for the surgeon is most likely to have better and safer outcomes in the long run. Our only concern is its cost effectiveness and we believe that if the cost factor is removed more and more surgeons will use the technology and it will increase the spectrum and the reach of minimally invasive thoracic surgery. This article reviews worldwide experience with robotic thoracic surgery and addresses the potential benefits and limitations of using the robotic platform for the performance of thoracic surgical procedures.

PurposeThis study was designed to investigate thoracic duct collateral leakage and the supply route of lymphatic fluid by lymphangiography and transcatheter thoracic ductography and to evaluate the results of embolization for thoracic duct collateral leakage performed to cut off this supply route.MethodsData were retrospectively collected from five patients who underwent embolization for thoracic duct collateral leakage in persistent high-output chylothorax after thoracic surgery. Extravasation of lipiodol at the ruptured thoracic duct collaterals was confirmed in all patients on lymphangiography. Transcatheter thoracic ductography was used to identify extravasation of iodinated contrast agent and to identify communication between the thoracic duct and leakage site. Thoracic duct embolization (TDE) was performed using the percutaneous transabdominal approach to cut off the supply route using N-butyl cyanoacrylate (NBCA) mixed with lipiodol (1:5–1:20).ResultsClinical success (drainage volume ≤10 mL/kg/day within 7 days after TDE) was achieved in all patients. The collateral routes developed as consequence of surgical thoracic duct ligation. In three patients, NBCA-Lipiodol reached the leakage site through direct communication between the thoracic duct and the ruptured lymphatic duct. In the other two patients, direct communication and extravasation was not detected on thoracic ductography, and NBCA-Lipiodol did not reach the leakage site. However, NBCA-Lipiodol did reach the cisterna chyli, lumbar trunks, and some collateral routes via the cisterna chyli or lumbar lymphatics. As a result, leakage was stopped.ConclusionsTDE was effective for the management of leakage of the collaterals in high-output chylothorax after thoracic surgery.

Gunshot wounds are rare events in European countries, but stab and impalement injuries occur more frequently and are often spectacular. The aim of the study was to describe several types of penetrating abdomino-thoracic injuries as well as the appropriate surgical interventions, including complex wound management. The representative case series includes four patients with abdomino-thoracic penetrating trauma (two impalements and two stabbings), who were treated in a surgical university hospital (tertiary) centre during a 12-month period. 1. A man was impaled on a steel pipe, which entered the body above the right kidney and behind the liver through the mediastinum via the right thorax, passing the heart and aortic arch up to the left clavicle. The rod was removed via sternotomy and median laparotomy. Only the left subclavian vein required repair. Postoperatively, a residual lesion of the left brachial plexus caused temporary pneumonia. 2. A leg of a collapsing chair drilled into a woman's left foramen obturatorium and exited the body at the right anterior iliac spine. At a regional hospital, the chair leg was removed and the canal caused by gluteal penetration was excised. Exploratory laparotomy revealed peritonitis resulting from a perforated ileum. The injury was repaired with segmental resection and anastomosis. Postoperative right inguinal wound necrosis necessitated excision and vacuum-assisted closure sealing. The patient has residual paresthesia in her left leg resulting from a sacral plexus lesion. 3. During an altercation, a man was stabbed twice in the right thorax. The right pulmonary lobe, the diaphragm, and the liver dome between segment VIII and V were injured. The patient also had a large scalp avulsion at the left and right parietooccipital site and transection of the biceps muscle at the middle third of the right humerus. The chest injuries, approached via right subcostal incision and right anterior thoracotomy were managed with liver packing (two

Surgical site infections (SSIs) increase morbidity and mortality rates and generate additional cost for the healthcare system. Pre-operative blood transfusion and the subcutaneous fat thickness (SFT) have been described as risk factors for SSI in other surgical areas. The purpose of this study was to assess the impact of pre-operative blood transfusion and the SFT on the occurrence of SSI in posterior thoracic spine surgery. In total, 244 patients (median age 55 y; 97 female) who underwent posterior thoracic spine fusions from 2008 to 2012 were reviewed retrospectively. Patient-specific characteristics, pre-operative hemoglobin concentration/hematocrit values, the amount of blood transfused, and the occurrence of a post-operative SSI were documented. The SFT was measured on pre-operative computed tomography scans. Surgical site infection was observed in 26 patients (11%). The SFT was 13 mm in patients without SSI and 14 mm in those with infection (p=0.195). The odds ratio for patients with pre-operative blood transfusion to present with SSI was 3.1 (confidence interval [CI] 1.4-7.2) and 2.7 (CI 1.1-6.4) when adjusted for age. There was no difference between the groups with regard to pre-operative hemoglobin concentration (p=0.519) or hematocrit (p=0.908). The SFT did not differ in the two groups. Allogeneic red blood cell transfusion within 48 h prior to surgery was an independent risk factor for SSI after posterior fusion for the fixation of thoracic spine instabilities. Pre-operative blood transfusion tripled the risk, whereas SFT had no influence on the occurrence of SSI.

Nanotechnology is an emerging, rapidly evolving field with the potential to significantly impact care across the full spectrum of cancer therapy. Of note, several recent nanotechnological advances show particular promise to improve outcomes for thoracic surgical patients. A variety of nanotechnologies are described that offer possible solutions to existing challenges encountered in the detection, diagnosis and treatment of lung cancer. Nanotechnology-based imaging platforms have the ability to improve the surgical care of patients with thoracic malignancies through technological advances in intraoperative tumour localization, lymph node mapping and accuracy of tumour resection. Moreover, nanotechnology is poised to revolutionize adjuvant lung cancer therapy. Common chemotherapeutic drugs, such as paclitaxel, docetaxel and doxorubicin, are being formulated using various nanotechnologies to improve drug delivery, whereas nanoparticle (NP)-based imaging technologies can monitor the tumour microenvironment and facilitate molecularly targeted lung cancer therapy. Although early nanotechnology-based delivery systems show promise, the next frontier in lung cancer therapy is the development of 'theranostic' multifunctional NPs capable of integrating diagnosis, drug monitoring, tumour targeting and controlled drug release into various unifying platforms. This article provides an overview of key existing and emerging nanotechnology platforms that may find clinical application in thoracic surgery in the near future. © The Author 2016.

Pain after surgery is a major handicap for patients as it bounds and decreases ability for spontaneous movement, cough and deep breathing, aiding the onset of complications and invalidating the recovery capabilities of operated patients. In thoracic surgery, the need to compile and employ guidelines for post-surgical pain management has become a pressing requirement in recent years. Currently available protocols include several options of treatment that are frequently a subject in the most recent scientific papers and play a key role, as they constitute the framework upon which building with changes and fixes that take account of incidental circumstances, in relation to both patients and surgery, again for both the organizational and structural features of the surgical environment. Purpose of this job is a thorough analysis of post-operating analgesic treatments for thoracic surgery, introducing the most effective ones currently available as for channels and procedures of administration, as well as possible side effects or complications.

In an effort to stimulate residents and trainers to increase their use of simulation training and the Thoracic Surgery Curriculum, a gamification strategy was developed in a friendly but competitive environment. "Top Gun." Low-fidelity simulators distributed annually were used for the technical competition. Baseline and final video assessments were performed, and 5 finalists were invited to compete in a live setting from 2013 to 2015. "Jeopardy." A screening examination was devised to test knowledge contained in the Thoracic Surgery Curriculum. The top 6 2-member teams were invited to compete in a live setting structured around the popular game show Jeopardy. "Top Gun." Over 3 years, there were 43 baseline and 34 final submissions. In all areas of assessment, there was demonstrable improvement. There was increasing evidence of simulation as seen by practice and ritualistic behavior. "Jeopardy." Sixty-eight individuals completed the screening examination, and 30 teams were formed. The largest representation came from the second-year residents in traditional programs. Contestants reported an average in-training examination percentile of 72.9. Finalists reported increased use of the Thoracic Surgery Curriculum by an average of 10 hours per week in preparation. The live competition was friendly, engaging, and spirited. This gamification approach focused on technical and cognitive skills, has been successfully implemented, and has encouraged the use of simulators and the Thoracic Surgery Curriculum. This framework may capitalize on the competitive nature of our trainees and can provide recognition of their achievements. Copyright © 2015 The American Association for Thoracic Surgery.

Nevertheless, 18–30% of cases managed only with tube thoracostomy have residual clotted blood, considered the major risk factor for the development of fibrothorax and empyema. In addition, 4–23% of chest injury patients present persistent pneumothorax and 15–59% present an injury to the diaphragm, which is missed in 30% of cases. In order to make a correct diagnosis, reduce the number of missed injuries, chronic sequelae and late mortality we propose performing surgical exploration of all patients with a penetrating injury of the pleural cavity. Methods 1270 patients who sustained thoracic trauma were admitted to our hospital between 1994 and 2004. Of these, 16 patients had penetrating injuries: thirteen were surgically explored by means of Video Assisted Thoracic Surgery (VATS, and 3 with thoracotomy due to hemodynamic instability or suspected lesion of the heart or great vessels. Results In the 13 patients who underwent VATS, 5 injuries to the diaphragm, 3 lesions to an intercostal artery, and 1 lesion to the diaphragmatic artery were detected. In 12 of these patients a laceration of the pulmonary parenchyma was also present. A conversion to thoracotomy was necessary due to a broad laceration of the diaphragm and due to hemostasis of an intercostal artery. In all but one case, which was later converted, diagnostic imaging missed the diagnosis of laceration of the diaphragm. There was no intra- or postoperative mortality, and average hospital stay was five days. Conclusion VATS is a safe and effective way to diagnose and manage penetrating thoracic injuries, and its extensive use leads to a reduction in the number of missed, potentially fatal lesions as well as in chronic sequelae.

Thoracic surgeons participating in this survey seemed to have clearly indicated their perception of VATS major lung resections, in particular VATS lobectomy. 1. The acronym VATS as a short form of "video-assisted thoracic surgery" was the preferred terminology. 2. According to the respondents, the need or use of rib spreading served as the defining characteristic of "open" thoracic surgery. 3. It was most commonly suggested that VATS lobectomy is performed by means of two or three port incisions with the addition of a minithoracotomy or access incision. 4. Rib spreading (shearing) was not deemed acceptable as part of a strictly defined VATS procedure. 5. Although there was no general consensus, respondents suggested that the preferred approach for visualization in a VATS procedure was only through the video monitor. 6. Although minimally invasive procedures for lung resection are still mainly being used for diagnostic and minor therapeutic purposes, young surgeons seemed to be more likely to recommend VATS lung surgery for major pulmonary resections than their more senior colleagues. 7. The survey confirmed that the use of the standard posterolateral thoracotomy is still widespread. Almost 40% of the surgeons claimed to use the standard posterolateral thoracotomy for more than 50% of their cases and less than 30% use it for less than 5% of cases. 8. The major reasons to perform VATS lobectomy were perceived to be reduced pain and decreased hospitalization. 9. Approximately 60% of the surgeons claimed to perform VATS lobectomy in less than 5% of their lobectomy cases. Younger consultants reported using VATS lobectomy in up to 50% of their lobectomy cases. There was the suggestion that lack of resources could justify the minor impact of VATS lobectomy in the thoracic surgical practice in middle- to low-income countries. 10. The currently available scientific evidence on safety and effectiveness, and technologic advancements were emphasized as the two factors having a

The patient with thoracic aortic disease can present for open or endovascular repair. Thoracic endovascular aortic repair (TEVAR) has emerged as a minimally invasive option for a multitude of aortic pathology, including dissections, aneurysms, traumatic injuries, and ulcers. Postoperative management of these patients depends on the extent of procedure, whether it was open or endovascular, and, finally, on the preoperative comorbidities present. While procedural success has catapulted TEVAR to popularity, midterm results have been mixed. Additionally, periprocedural complications such as paraplegia and renal failure remain a significant morbidity in these patients. © The Author(s) 2015.

Full Text Available Objective: Thoracic outlet syndrome is a complex disorder caused by neurovascular irritation in the region of the thoracic outlet. The syndrome have been said to be mainly due to anomalous structures in the thoracic outlet, treatment for thoracic outlet syndrome varies among different institutions, and there has not been any standard program. In general conservative and surgical treatment can be do if necessary. Materials & Methods: The rehabilitation program consists of exercise and physiotherapy and brace designed to hold the posture in which thoracic outlet is enlarged. Exercise program was designed simple enough to be performed in the daily living or during work after minimal training and isometric exercises of Serratus anterior, Levator Scapulae and Erector Spinae muscles to be performed in one posture: flexion and elevation of scapular girdle and correction position of upper-thoracic spine. During 7 years, 131 cases of (T.O.S. were evaluated that 26 cases (20% have operated and 84 cases (64% have treated with conservative treatment and 21 cases (16% have been candidate for surgery but they didn't accepted. Results: All of the cases have treated with conservative treatment for four months. 84 cases responded well and no further treatment was needed. 47 cases were not satisfied with. The outcome of their treatment, that 26 cases have operated and 21 cases have not accepted the operation and continued the conservative treatment, they have had pain and slightly disability. 23 cases of operated group responded well and they have resumed to work, one case has had neuropraxia for about one year. Conclusion: Most cases of thoracic outlet syndrome (T.O.S. can be treated conservatively. Surgically treatment is indicated only in cases severe enough to make them disable to work. It is better all the patients undergo conservative treatment for at least four months then will decided for surgical treatment.

Full Text Available Background/Aim. Thoracic drainage is a surgical procedure for introducing a drain into the pleural space to drain its contents. Using this method, the pleura is discharged and set to the physiological state which enables the reexpansion of the lungs. The aim of the study was to prove that the use of modern principles and protocols of thoracic drainage significantly reduces the occurrence of failures and complications, rendering the treatment more efficient. Methods. The study included 967 patients treated by thoracic drainage within the period from January 1, 1989 to June 1, 2000. The studied patients were divided into 2 groups: group A of 463 patients treated in the period from January 1, 1989 to December 31, 1994 in whom 386 pleural drainage (83.36% were performed, and group B of 602 patients treated form January 1, 1995 to June 1, 2000 in whom 581 pleural drainage (96.51% were performed. The patients of the group A were drained using the classical standards of thoracic drainage by the general surgeons. The patients of the group B, however, were drained using the modern standards of thoracic drainage by the thoracic surgeons, and the general surgeons trained for this kind of the surgery. Results. The study showed that better results were achieved in the treatment of the patients from the group B. The total incidence of the failures and complications of thoracic drainage decreased from 36.52% (group A to 12.73% (group B. The mean length of hospitalization of the patients without complications in the group A was 19.5 days versus 10 days in the group B. The mean length of the treatment of the patients with failures and complications of the drainage in the group A was 33.5 days versus 17.5 days in the group B. Conclusion. The shorter length of hospitalization and the lower morbidity of the studied patients were considered to be the result of the correct treatment using modern principles of thoracic drainage, a suitable surgical technique, and a

The evolution of thoracic anesthesia.

Brodsky, Jay B

2005-02-01

The specialty of thoracic surgery has evolved along with the modem practice of anesthesia. This close relationship began in the 1930s and continues today. Thoracic surgery has grown from a field limited almost exclusively to simple chest wall procedures to the present situation in which complex procedures, such as lung volume reduction or lung transplantation, now can be performed on the most severely compromised patient. The great advances in thoracic surgery have followed discoveries and technical innovations in many medical fields. One of the most important reasons for the rapid escalation in the number and complexity of thoracic surgical procedures now being performed has been the evolution of anesthesia for thoracic surgery. There has been so much progress in this area that numerous books and journals are devoted entirely to this subject. The author has been privileged to work with several surgeons who specialized in noncardiac thoracic surgery. As a colleague of 25 years, the noted pulmonary surgeon James B.D. Mark wrote, "Any operation is a team effort... (but) nowhere is this team effort more important than in thoracic surgery, where near-choreography of moves by all participants is essential. Exchange of information, status and plans are mandatory". This team approach between the thoracic surgeon and the anesthesiologist reflects the history of the two specialties. With new advances in technology, such as continuous blood gas monitoring and the pharmacologic management of pulmonary circulation to maximize oxygenation during one-lung ventilation, in the future even more complex procedures may be able to be performed safely on even higher risk patients.

Imaging of thoracic trauma

Blunt trauma to the chest results from transfer of kinetic energy to the human body. It may cause a wide range of mostly life-threatening injuries, including fractures of the thoracic skeleton, disintegration of the pleural space, contusion or laceration of pulmonary parenchyma and damage to the mediastinal structures. For a systematic approach it may be helpful to follow an organ-based evaluation of thoracic trauma. However, it should be borne in mind that subtle injuries may be associated with serious complications. Trauma to the chest may affect different anatomic compartments at the same time, requiring and extending diagnostic approach. Conventional radiography plays a major role in diagnosting thoracic trauma, complemented by ultrasound examination of the pleura and abdomen. It is well documented that CT scanning represents a major technological improvement for assessment of thoracic trauma. With the advent of fast helical CT scanning this method becomes more applicable for severly traumatized patients and potentially replaces other time-consuming procedures. State-of-the-art imaging of both projection and cross-sectional techniques provides useful information for immediate and appropriate treatment mandatory in patients with thoracic trauma. (orig.) [de

The purpose of this study is to review the role of telemedicine in providing oncology care; we describe our long-standing, high-volume telemedicine experience. The Interior Health Thoracic Surgical Group (IHTSG) uses telemedicine, through Virtual Thoracic Surgical Clinics (VTSC), to provide service to remote patients. The IHTSG serves a population of 1.01 million people over an area of 807,538 km 2 (1.3 persons/km 2 ) in the Interior and North of British Columbia, Canada. Between 2003 and 2015, the IHTSG conducted 15,073 telemedicine patient encounters at 63 geographic sites. Telemedicine saved these patients a total travel distance of 11.5 million km-an average of 766 km per patient. VTSC supports and strengthens the Hub and Spoke model of healthcare delivery-patients residing remotely can easily access centrally delivered service. Telemedicine makes specialized care available to all patients by overcoming a major impediment to access, namely distance.

Objective Conventional, separate mediastinal and pleural tubes are often inefficient at draining thoracic effusions. Description We developed a Y-shaped chest tube with split ends that divide within the thoracic cavity, permitting separate intrathoracic placement and requiring a single exit port. In this study, thoracic drainage by the split drain vs. that of separate drains was tested. Methods After sternotomy, pericardiotomy, and left pleurotomy, pigs were fitted with separate chest drains (n=10) or a split tube prototype (n=9) with internal openings positioned in the mediastinum and in the costo-diaphragmatic recess. Separate series of experiments were conducted to test drainage of D5W or 0.58 M sucrose, an aqueous solution with viscosity approximating that of plasma. One litre of fluid was infused into the thorax, and suction was applied at −20 cm H2O for 30 min. Results When D5W was infused, the split drain left a residual volume of 53 ± 99 ml (mean value ± SD) vs. 148 ± 120 for the separate drain (P=0.007), representing a drainage efficiency (i.e. drained vol/[drained + residual vol]) of 95 ± 10% vs. 86 ± 12% for the separate drains (P = 0.011). In the second series, the split drain evacuated more 0.58 M sucrose in the first minute (967 ± 129 ml) than the separate drains (680 ± 192 ml, Pdrain evacuated a similar volume of sucrose vs. the conventional drain (1089 ± 72 vs. 1056 ± 78 ml; P = 0.5). Residual volume tended to be lower (25 ± 10 vs. 62 ± 72 ml; P = 0.128) and drainage efficiency tended to be higher (98 ± 1 vs. 95 ± 6%; P = 0.111) with the split drain vs. conventional separate drains. Conclusion The split chest tube drained the thoracic cavity at least as effectively as conventional separate tubes. This new device could potentially alleviate postoperative complications.

Hale, Diane F; Sexton, Justin C; Benavides, Linda C; Benavides, Jerry M; Lundy, Jonathan B

The deployment of surgical assets has been driven by mission demands throughout years of military operations in Iraq and Afghanistan. The transition to the highly expeditious Golden Hour Offset Surgical Transport Team (GHOST- T) now offers highly mobile surgical assets in nontraditional operating rooms; the content of the surgical instrument sets has also transformed to accommodate this change. The 102nd Forward Surgical Team (FST) was attached to Special Operations assigned to southern Afghanistan from June 2015 to March 2016. The focus was to decrease overall size and weight of FST instrument sets without decreasing surgical capability of the GHOST-T. Each instrument set was evaluated and modified to include essential instruments to perform damage control surgery. The overall number of main instrument sets was decreased from eight to four; simplified augmentation sets have been added, which expand the capabilities of any main set. The overall size was decreased by 40% and overall weight decreased by 58%. The cardiothoracic, thoracotomy, and emergency thoracotomy trays were condensed to thoracic set. The orthopedic and amputation sets were replaced with an augmentation set of a prepackaged orthopedic external fixator set). An augmentation set to the major or minor basic sets, specifically for vascular injuries, was created. Through the reorganization of conventional FST surgical instrument sets to maintain damage control capabilities and mobility, the 102nd GHOST-T reduced surgical equipment volume and weight, providing a lesson learned for future surgical teams operating in austere environments. 2017.

One-stage sequential bilateral thoracic expansion for asphyxiating thoracic dystrophy (Jeune syndrome).

2014-10-01

Jeune syndrome (asphyxiating thoracic dystrophy) is a rare disorder characterized by skeletal dysplasia, reduced diameter of the thoracic cage and extrathoracic organ involvement. Fatal, early respiratory insufficiency may occur. Two-stage lateral thoracic expansion has been reported, addressing each side sequentially over 3-12 months. While staged repair theoretically provides less invasive surgery in a small child with respiratory distress, we utilized a single stage, bilateral procedure aiming to rapidly maximize lung development. Combined bilateral surgery also offered the chance of rapid recovery, and reduced hospital stay. We present our early experience of this modification of existing surgical treatment for an extremely rare condition, thought to be generally fatal in early childhood. Nine children (6 males, 3 females; median age 30 months [3.5-75]) underwent thoracic expansion for Jeune syndrome in our centre. All patients required preoperative respiratory support (5 with tracheostomy, 8 requiring positive pressure ventilation regularly within each day/night cycle). Two children underwent sequential unilateral (2-month interval between stages) and 7 children bilateral thoracic expansion by means of staggered osteotomies of third to eighth ribs and plate fixation of fourth to fifth rib and sixth to seventh rib, leaving the remaining ribs floating. There was no operative mortality. There were 2 deaths within 3 months of surgery, due to pulmonary hypertension (1 following two-stage and 1 following single-stage thoracic expansion). At the median follow-up of 11 months (1-15), 3 children have been discharged home from their referring unit and 2 have significantly reduced respiratory support. One child remains on non-invasive ventilation and another is still ventilated with a high oxygen requirement. Jeune syndrome is a difficult condition to manage, but bilateral thoracic expansion offers an effective reduction in ventilator requirements in these children

Optimal surgical approach to thymic malignancies: New trends challenging old dogmas.

Until recently, the surgical approach to thymic tumors has remained basically unchanged. The collaborative effort led by ITMIG with the collaboration of regional and society-based interest groups (ESTS, JART) produced an enthusiastic surge of interest in testing the new technological advances in thoracic surgery and many historical dogmas in thymic surgery have been questioned and challenged. The present review addresses the new trends in the optimal surgical management of thymic tumors based on the review of the current literature. 1. Minimally-invasive techniques (MIT) including video-assisted thoracic surgery (VATS) and robotic-assisted thoracic Surgery (RATS) are now to be considered the standard of care in early-stage thymic tumors. MIT are no inferior to open approaches in terms of postoperative complications, loco-regional recurrence rates and survival. MIT are associated with a shorter length of stay, reduced intraoperative blood loss and better cosmetic results. 2. The adoption of the ITMIG/IASLC TNM staging system for thymic tumors requires a paradigm shift among thoracic surgeons to include regional lymphadenectomy according to the IASLC/ITMIG nodal map in the surgical management of thymic tumors. 3. A limited thymectomy instead of total thymectomy along with the removal of the thymic tumor in nonmyasthenic Stage I-II tumors has been proposed by some authors, although the results are not uniform. Until more mature data is available, adherence to the current guidelines recommending total thymectomy in addition to thymomectomy is always indicated. 4. In locally-advanced Stage IVa patients with pleural involvement, major pleural resections, including pleurectomy/decortication or extrapleural pneumonectomy are indicated, provided a complete resection of the pleural deposits is anticipated, usually in a multidisciplinary setting, with excellent long-term results. The incorporation of these new concepts and techniques in the surgical armamentarium of the

Thoracic disc prolapses causing cord compression can be challenging. For compressive central disc protrusions, a posterior approach is not suitable due to an unacceptable level of cord manipulation. An anterolateral transthoracic approach provides direct access to the disc prolapse allowing for decompression without disturbing the spinal cord. In this video, we describe 2 cases of thoracic myelopathy from a compressive central thoracic disc prolapse. In both cases, informed consent was obtained. Despite similar radiological appearances of heavy calcification, intraoperatively significant differences can be encountered. We demonstrate different surgical strategies depending on the consistency of the disc and the adherence to the thecal sac. With adequate exposure and detachment from adjacent vertebral bodies, soft discs can be, in most instances, separated from the theca with minimal cord manipulation. On the other hand, largely calcified discs often present a significantly greater challenge and require thinning the disc capsule before removal. In cases with significant adherence to dura, in order to prevent cord injury or cerebrospinal fluid leak a thinned shell can be left, providing total detachment from adjacent vertebrae can be achieved. Postoperatively, the first patient, with a significantly calcified disc, developed a transient left leg weakness which recovered by 3-month follow-up. This video outlines the anatomical considerations and operative steps for a transthoracic approach to a central disc prolapse, whilst demonstrating that computed tomography appearances are not always indicative of potential operative difficulties.

Early pain and persistent parietal disorders remains a major unresolved problem in thoracic surgery. Thoracotomy and the use of multiple ports in most Video Assisted Thoracic Surgery (VATS) procedures are the major cause of this persistent pain. For the last decade, a few publications describing the use of either single incision VATS and cervical thoracic approaches have been reported without significant results in comparison with current used techniques. Intercostals compression during surgery and early after by intercostals chest tube placement, are probably the major cause of postoperative pain. Flexible endoscope is currently used in several surgeries and will take more and more importance in our daily use in thoracic surgery. Instrument flexibility allows its use through minimally invasive approaches and offers a very interesting intra-thoracic navigation. We describe here the first use in France of a flexible endoscope in thoracic surgery through a single cervical incision to perform simultaneous exploration and biopsies of the mediastinum and right pleura using the original approach of Cervical Incision Thoracic Endoscopic Surgery (CITES).

Abstract Treating thoracic infective spondylodiscitis with anterior surgical approaches carry a relatively high risk of perioperative and postoperative complications. Posterior approaches have been reported to result in lower complication rates than anterior procedures, but more evidence is needed to demonstrate the safety and efficacy of 1-stage posterior approaches for treating infectious thoracic spondylodiscitis. Preoperative and postoperative clinical data, of 18 patients who underwent 2...

Purpose: To describe and discuss the thoracic CT features of hypovolemic shock. Material and Methods: From a group of 18 patients with signs of hypovolemia on contrast-enhanced abdominal CT, 11 were selected for our study as having also undergone a complete chest examination. Pulse rate, blood pressure, trauma score value, Glasgow coma scale value, surgical result, and final outcome were retrospectively evaluated. The CT features analyzed were: decreased cardiac volume, reduced caliber of the thoracic aorta, aortic branches and caval venous system, increased enhancement of the aorta, and increased enhancement of the pulmonary collapses/contusions. Results: All 11 subjects presented severe injuries and hemodynamic instability; 7 were stable enough to undergo surgery; only 1 of the 11 survived. Two patients showed none of the features of thoracic hypovolemia. All the other patients presented at least two signs: reduced caliber of the thoracic aorta in 7 cases; decreased volume of the cardiac chambers and increased aortic enhancement in 6; decreased caliber of the aortic vessels in 4; decreased caliber of the caval veins in 3; and increased enhancement of the pulmonary collapses/contusions in 3. Conclusions: In patients with hypovolemia, CT may show several thoracic findings in addition to abdominal ones. Knowledge of these features is important for distinguishing them from traumatic injuries. (orig.)

To determine the effect of elective thoracic surgery on energy metabolism and gas exchange and to evaluate whether the 30-degree sitting position would affect these variables. Prospective, unblinded, controlled study. Surgical ICU in a university hospital. Twenty-two adult patients undergoing elective pulmonary resection. Posture change from supine to 30-degree sitting position. Oxygen consumption (VO2), carbon dioxide production (VCO2), respiratory quotient (RQ), and energy expenditure (EE) were measured by means of computerized indirect calorimetry before and after surgery. Heart rate and respiratory frequency were measured continuously during gas exchange measurement. Blood gases were analyzed with an automated blood gas analyzer. Preoperatively, altering position did not affect energy metabolism, gas exchange, and cardiopulmonary variables. Postoperatively, the measured EE was 116% of the expected value. Mean EE and VO2 values for each position were higher than the preoperative values for the corresponding postures (pMean percent increases in EE, VO2, and VCO2 were significantly lower in the 30-degree sitting position than in the supine position (EE: 7.9+/-2.7% vs 14.4+/-2.3%; pexchange for each position were worse than the preoperative values for the corresponding postures (pMean arterial pressure, heart rate, and respiratory frequency for each position were higher than the preoperative values for the corresponding postures (pmean values of these variables occurred between the two positions postoperatively. The early postoperative period of patients undergoing elective thoracic surgery is characterized by a condition of impaired gas exchange and by a hypermetabolic state. Hypermetabolism can be partly mitigated by assuming the 30-degree sitting position.

Objectives Emergency thoracic surgery in the elderly represents an extreme situation for both the surgeon and patient. The lack of an adequate patient history as well as the inability to optimize any co-morbidities, which are the result of the emergent situation, are the cause of increased morbidity and mortality. We evaluated the outcome and prognostic factors for this selected group of patients. Design Retrospective chart review. Setting Academic tertiary care referral center. Participants Emergency patients treated at the Department of Thoracic Surgery, University Hospital of Luebeck, Germany. Main outcome measures Co-morbidities, mortality, risk factors and hospital length of stay. Results A total of 124 thoracic procedures were performed on 114 patients. There were 79 men and 36 women (average age 72.5 ±6.4 years, range 65–94). The overall operative mortality was 25.4%. The most frequent indication was thoracic/mediastinal infection, followed by peri- or postoperative thoracic complications. Risk factors for hospital mortality were a high ASA score, pre-existing diabetes mellitus and renal insufficiency. Conclusions Our study documents a perioperative mortality rate of 25% in patients over 65 who required emergency thoracic surgery. The main indication for a surgical intervention was sepsis with a thoracic/mediastinal focus. Co-morbidities and the resulting perioperative complications were found to have a significant effect on both inpatient length of stay and outcome. Long-term systemic co-morbidities such as diabetes mellitus are difficult to equalize with respect to certain organ dysfunctions and significantly increase mortality. PMID:21369531

English Major Trauma Centres (MTCs) were established in April 2012. Increased case volume and complexity has influenced trauma and orthopaedic (T&O) core surgical training in these centres. To determine if T&O core surgical training in MTCs meets Joint Committee on Surgical Training (JCST) quality indicators including performance of T&O operative procedures and consultant supervised session attendance. An audit cycle assessing the impact of a weekly departmental core surgical trainee rota. The rota included allocated timetabled sessions that optimised clinical and surgical learning opportunities. Intercollegiate Surgical Curriculum Programme (ISCP) records for T&O core surgical trainees at a single MTC were analysed for 8 months pre and post rota introduction. Outcome measures were electronic surgical logbook evidence of leading T&O operative procedures and consultant validated work-based assessments (WBAs). Nine core surgical trainees completed a 4 month MTC placement pre and post introduction of the core surgical trainee rota. Introduction of core surgical trainee rota significantly increased the mean number of T&O operative procedures led by a core surgical trainee during a 4 month MTC placement from 20.2 to 34.0 (pcore surgical trainee during a 4 month MTC placement was significantly increased (0.3 vs 2.4 [p=0.04]). Those of dynamic hip screw fixation (2.3 vs 3.6) and ankle fracture fixation (0.7 vs 1.6) were not. Introduction of a core surgical trainee rota significantly increased the mean number of consultant validated WBAs completed by a core surgical trainee during a 4 month MTC placement from 1.7 to 6.6 (pcore surgical trainee rota utilising a 'problem-based' model can significantly improve T&O core surgical training in MTCs.

Recent publications from North America have shown the benefits of robot-assisted thoracic surgery. We report here the process of setting up such a program in a French university centre and early results in a unit with an average treatment volume. Retrospective review of a single institution database. The program was launched after a 6-month preparation period. From January 2012 to January 2013, totally endoscopic, full robot-assisted procedures were performed on 30 patients (17 males). Median age was 54 [Q1-Q3, 48-63] years and ASA score 2 [1,2]. Operative procedures included thymectomy (9 ; 30%), lobectomy with nodes resection (11 ; 38%), segmentectomy (4 ; 14%), lymphadenectomy (3 ; 10%), Bronchogenic cyst (2, 5%) and posterior mediastinal mass resection (1 ; 3%). No conversion was required. Median blood loss was 50mL [10-100]. Median operating time was 135 min (105-165) including 30 min [20-40] for docking, 90min for robot-assisted operating [70-120] and 15 min [10-15] for lesion extraction. CO2 insufflation was used in 28 cases (93%). Hospital stay was 4 days [4-6] with 6 minor complications (20%) (Grade 1 according to the Clavien-Dindo classification). After a median 4 months follow-up [2-7], all patients were alive and demonstrated a good quality of life. This series suggests that full robotic thoracic procedures are safe and effective treatment for various pathologies, with low morbidity and without a significant learning curve, even in a lower volume centre. This technology should accompany the development of minimally invasive thoracic surgery. The importance of robotic training should be emphasized to optimize procedures and costs.

Degenerative spondylolisthesis of the spine is less common in the lower thoracic region than in the lumbar and cervical regions. However, lower thoracic degenerative spondylolisthesis may develop secondary to intervertebral disc degeneration. Most of our patients are found to have concomitant lumbar spondylosis. By retrospective review of our cases, current diagnosis and treatments for this rare disease were discussed. We present a series of 5 patients who experienced low back pain, progressive numbness, weakness and even paraparesis. Initially, all of them were diagnosed with lumbar spondylosis at other clinics, and 1 patient had even received prior decompressive lumbar surgery. However, their symptoms continued to progress, even after conservative treatments or lumbar surgeries. These patients also showed wide-based gait, increased deep tendon reflex (DTR), and urinary difficulty. All these clinical presentations could not be explained solely by lumbar spondylosis. Thoracolumbar spinal magnetic resonance imaging (MRI), neurophysiologic studies such as motor evoked potential (MEP) or somatosensory evoked potential (SSEP), and dynamic thoracolumbar lateral radiography were performed, and a final diagnosis of lower thoracic degenerative spondylolisthesis was made. Bilateral facet effusions, shown by hyperintense signals in T2 MRI sequence, were observed in all patients. Neurophysiologic studies revealed conduction defect of either MEP or SSEP. One patient refused surgical management because of personal reasons. However, with the use of thoracolumbar orthosis, his symptoms/signs stabilized, although partial lower leg myelopathy was present. The other patients received surgical decompression in association with fixation/fusion procedures performed for managing the thoracolumbar lesions. Three patients became symptom-free, whereas in 1 patient, paralysis set in before the operation; this patient was able to walk with assistance 6 months after surgical decompression

Full Text Available Abstract Background Chylothorax is a rare form of pleural effusion that can be associated with both traumatic and non-traumatic causes. Thoracic duct ligation is often the treatment of choice in postsurgical patients; however the optimal treatment of this disease process after traumatic injury remains unclear 1. We present a rare case of a thoracic duct injury secondary to a blunt thoracic spine fracture and subluxation which was successfully treated non-operatively. Case Presentation A 51 year old male presented as a tier one trauma code due to an automobile versus bicycle collision. His examination and radiographic work-up revealed fractures and a subluxation at the third and fourth thoracic spine levels resulting in paraplegia. He also sustained bilateral hemothoraces secondary to multiple rib fractures. Drainage of the left hemothorax led to the diagnosis of a traumatic chylothorax. The thoracic spine fractures were addressed with surgical stabilization and the chylothorax was successfully treated with drainage and dietary manipulation. Conclusions This unusual and complex blunt thoracic duct injury required a multidisciplinary approach. Although the spine injury required surgical fixation, successful resolution of the chyle leak was achieved without surgical intervention.

intraluminal stent implantation is an alternative. Objective: to analyze the impact of percutaneous implantation of aortic stents in high-risk surgical patients with a minimum of one y ear follow-up. Method: Descriptive study conducted from December 2005 to March 2010 which included 125 patients with thoracic or abdominal aortic aneurysm, meeting surgical criteria by its diameter and that were rejected from surgery due to their high risk. The outcomes were intraoperative death from any cause and aneurysm-related at one, six and twelve months. Complications were defined as vascular occurred during the first thirty days. Results: Abdominal aneurysm was more frequent (70.4%. The overall mortality at 25.7 months follow-up was 14.8%. Of this percentage, 5.2% died from causes related to the aneurysm. One patient died during surgery. 4.3% were reoperated for leaks. There was higher aneurysm-related mortality in the thoracic (14.7 vs. 1.2% p = 0.003 and a trend in those of larger diameter (6.9 vs. 5.7 cm p = 0.210. There was no association between mortality and diabetes mellitus, smoking, heart disease, hypertension or dyslipidemia. Conclusions: aneurysm-related mortality in patients undergoing aortic stent graft is low. Mortality was associated with thoracic aneurysm and to its greater diameter. Complications did not imply an increase in mortality. In conclusion, in patients with aortic aneurysm and high surgical risk rejected for open surgery, percutaneous approach is a safe and effective treatment in a medium-term follow-up.

To determine if there are advantages to transitioning to robotics by a surgeon who is already proficient in performing video-assisted thoracic surgical (VATS) lobectomy. A single surgeon proficient in VATS lobectomy initiated a robotic lobectomy program, and a retrospective review was conducted of his patients undergoing minimally invasive lobectomy (robotics or VATS) for lung cancer between 2011 and 2012. Data collected included patient/tumor characteristics, morbidity, mortality, operative times, and length of hospital stay. Over a 24-month period, a total of 69 patients underwent minimally invasive lobectomy (35 robotic, 34 VATS). Patients in each group were similar in age and clinical stage. Robotic upper lobectomy operative times were longer than VATS (172 vs 134 minutes; P = .001), with no significant difference in lower lobectomies noted (140 vs 123 minutes; P = .1). Median length of stay was 3 days in both groups, and the median number of lymph nodes harvested was 18 (robotic) versus 16 (VATS; P = .42). Morbidity and mortality for robotic versus VATS were 11% versus 18% (P = .46) and 0% versus 3% (P = .49), respectively. There does not seem to be a significant advantage for an established VATS lobectomy surgeon to transition to robotics based on clinical outcomes. The learning curve for robotic upper lobectomies seems to be more significant than that for lower lobectomies. Copyright © 2014 The American Association for Thoracic Surgery. Published by Mosby, Inc.

The status of citations can reflect the impact of a paper and its contribution to surgical practice. The aim of our study was to identify and review the 100 most-cited papers in general thoracic surgery. Relevant papers on general thoracic surgery were searched through Thomson Reuters Web of Science in the last week of November 2017. Results were returned in descending order of total citations. Their titles and abstracts were reviewed to identify whether they met our inclusion criteria by two thoracic surgeons independently. Characteristics of the first 100 papers, including title, journal name, country, first author, year of publication, total citations, citations in latest 5 years and average citation per year (ACY) were extracted and analyzed. Of the 100 papers, the mean number of citations was 322 with a range from 184 to 921. 19 journals published the papers from 1956 to 2012. Annals of Surgery had the largest number (29), followed by Journal of Thoracic and Cardiovascular Surgery (22) and Annals of Thoracic Surgery (21). The majority of the papers were published in 2000s (48) and originated from United States of America (62). There were 65 retrospective studies, 13 RCTs and 11 prospective studies. Orringer MB and Grillo HC contributed 4 first-author articles respectively. There were 53 papers on esophagus, 36 on lung, 6 on pleura and 5 on trachea. Our study identified the most-cited papers in the past several decades and offered insights into the development and advances of general thoracic surgery. It can help us understand the evidential basis of clinical decision-making today in the area. Copyright © 2018. Published by Elsevier Ltd.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database has been linked to the Social Security Death Master File to verify "life status" and evaluate long-term surgical outcomes. The objective of this study is explore practical applications of the linkage of the Society of Thoracic Surgeons Adult Cardiac Surgery Database to Social Securtiy Death Master File, including the use of the Social Securtiy Death Master File to examine the accuracy of the Society of Thoracic Surgeons 30-day mortality data. On January 1, 2008, the Society of Thoracic Surgeons Adult Cardiac Surgery Database began collecting Social Security numbers in its new version 2.61. This study includes all Society of Thoracic Surgeons Adult Cardiac Surgery Database records for operations with nonmissing Social Security numbers between January 1, 2008, and December 31, 2010, inclusive. To match records between the Society of Thoracic Surgeons Adult Cardiac Surgery Database and the Social Security Death Master File, we used a combined probabilistic and deterministic matching rule with reported high sensitivity and nearly perfect specificity. Between January 1, 2008, and December 31, 2010, the Society of Thoracic Surgeons Adult Cardiac Surgery Database collected data for 870,406 operations. Social Security numbers were available for 541,953 operations and unavailable for 328,453 operations. According to the Society of Thoracic Surgeons Adult Cardiac Surgery Database, the 30-day mortality rate was 17,757/541,953 = 3.3%. Linkage to the Social Security Death Master File identified 16,565 cases of suspected 30-day deaths (3.1%). Of these, 14,983 were recorded as 30-day deaths in the Society of Thoracic Surgeons database (relative sensitivity = 90.4%). Relative sensitivity was 98.8% (12,863/13,014) for suspected 30-day deaths occurring before discharge and 59.7% (2120/3551) for suspected 30-day deaths occurring after discharge. Linkage to the Social Security Death Master File confirms the accuracy of

To evaluate the detectability of tumor invasion to the thoracic inlet, MRI was performed in 57 patients with thoracic inlet tumor, and the diagnostic accuracy of MRI was compared with that of CT concerning the utility for thoracic inlet lesions. And we assessed abnormal findings in comparison with surgical or autopsy findings. In the local extent of the tumor, the accuracy for tumor invasion to the vessels such as subclavian artery and vein was 94.9% for MRI, and 83.5% for CT, and to the brachial plexus was 95.0% for MRI, and 60.0% for CT. MRI was superior to CT, but MRI was equivalent to CT with regard to invasion to the base of the neck, lateral chest wall, ribs, and vertebral bodies. However on MRI, it is easier to understand the longitudinal tumor extent than on CT. CT has superior spatial resolusion but CT has also disadvantages, such as streak artifact caused by shoulder joints, resulting in image degradation. In contrast, MRI has inherent advantages, and multiple images which facilitate the relationship between tumor and normal structures. Coronal and sagittal MR images facilitated three-dimensional observation of tumor of invasion in the thoracic inlet. Furthermore to improve image quality of MRI for the thoracic inlet, we newly devised a high molecular polyester shell for fixing a surface coil. On the high resolution MR (HR-MR) imaging using our shell, normal lymph nodes, muscles, blood vessels and the branches of the branchial plexus were clearly visualized in detail. Our shell was simple to process and facilitated immobilization of a surface coil. HR-MR technique produces images of high resolution after simple preparation. In conclusion, MRI was very useful for detecting lesions of the thoracic inlet and in deciding surgical indication and the planning for radiotherapy. (author).

Full Text Available INTRODUCTION Interest for traumatic thoracic aorta rupture stems from the fact that its number continually increases, and it can be rapidly lethal. OBJECTIVE The aim of this study is to present early and long term results as well as experiences of our team in surgical treatment of traumatic thoracic aorta rupture. METHOD Our retrospective study includes 12 patients with traumatic thoracic aorta rupture treated between 1985 and 2007. There were 10 male and two female patients of average age 30.75 years (18-74. RESULTS In six cases, primary diagnosis was established during the first seven days days after trauma, while in 6 more than one month later. In 11 cases, classical open surgical procedure was performed, while endovascular treatment was used in one patient. Three (25% patients died, while two (16.6% had paraplegia. Nine patients (75% were treated without complications, and are in good condition after a mean follow-up period of 9.7 years (from one month to 22 years. CONCLUSION Surgical treatment requires spinal cord protection to prevent paraplegia, using cardiopulmonary by-pass (three of our cases or external heparin-bonded shunts (five of our cases. Cardiopulmonary by-pass is followed with lower incidence of paraplegia, however it is not such a good solution for patients with polytrauma because of hemorrhage. The endovascular repair is a safe and feasible procedure in the acute phase, especially because of traumatic shock and polytrauma which contributes to higher mortality rate after open surgery. On the other hand, in chronic postrauamatic aortic rupture, open surgical treatment is connected with a lower mortality rate and good long-term results. There have been no published data about long-term results of endovascular treatment in the chronic phase.

Incidental Cardiac Findings on Thoracic Imaging.

The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.

Many surgical interventions have emerged as effective means of restoring mechanical stability of the anterior column of the spine. The lateral extracavitary approach (LECA) allows for broad visualization and circumferential reconstruction of the spinal column. However, early reports demonstrated significant complication rates, protracted operative times, and prolonged hospitalizations. More recent reports have highlighted concerns for subsidence, particularly with expandable cages. Our work seeks to describe a single-surgeon consecutive series of patients undergoing LECA for thoracic corpectomy. Specifically, the objective was to explore the surgical considerations, clinical and radiographic outcomes, and complication profile of this approach. A retrospective study examined data from 17 consecutive patients in whom single or multi-level corpectomy was performed via a LECA by a single surgeon. Vertebral body replacement was achieved with either a static or expandable titanium cage. The Karnofsky Performance Scale (KPS) was utilized to assess patient functional status before and after surgery. Radiographic outcomes, particularly footplate-to-body ratio and subsidence, were assessed on CT imaging at 6 weeks after surgery and at follow-up of at least 6 months. The majority of patients had post-operative KPS scores consistent with functional independence (≥70, 12/17 patients, 71%). Fourteen patients had improved or maintained function by last follow-up. In both groups, all patients had a favorable footplate-to-body ratio, and rates of subsidence were similar at both time points. Notably, the overall complication rate (24%) was significantly lower than that published in the literature, and no patient suffered a pneumothorax that required placement of a thoracostomy tube. The LECA approach for anterior column reconstruction with static or expandable cages is an important surgical consideration with favorable surgical parameters and complication rates. Further, use of

Thoracic Wall Necrotizing Fasccitiss in a Neonate: a Case Report

Full Text Available Necrotizing fasciitis (NF is a rapidly progressive and potentially life-threatening infection of superficial fascia and subcutaneous tissue. Thoracic wall is one of the rarest locations for NF. Broadspectrum antibiotics receiving, early surgical debridement, and skin grafting are life saving in NF. We report a 7-day-old female neonate who had left sided thoracic wall NF. She had undergone extensive surgical debridement within 4 hours of hospital admission, and reconstruction of skin defect by split-thickness skin grafting later. Early diagnosis is important, as prompt surgical debridement offers the best chance for survival. Early and extensive surgical debridement is a widely accepted clinical approach and the mainstay of effective treatment. The goals of surgical intervention are to remove all necrotic tissues, and to help control the progression of NF. Reconstruction of skin defects should be performed by early split-thickness skin grafting like our patient or primary closure. Because early wound resurfacing prevents fluid, electrolyte, and protein loss from the wound site, and decreases secondary infection. Although chest wall NF is rare in neonates, it is a rapidly spreading, highly lethal infection. A high index of suspicion, early diagnosis, and aggressive approach are essential to its successful treatment.

An innovative approach, the JAG tearing technique, was performed during thoracic endovascular aneurysm repair in a patient with previous surgical replacement of the ascending aorta with a residual uncomplicated type B aortic dissection who developed an aneurysm of the descending thoracic aorta with its lumen divided in two parts by an intimal flap. The proximal landing zone was suitable to place a thoracic stent graft. The distal landing zone was created by cutting the intimal flap in the distal third of the descending thoracic aorta with a radiofrequency guide wire and intravascular ultrasound catheter.

To report approach, technical success, safety, and short-term outcomes of thoracic duct stent-graft reconstruction for the treatment of chylothorax. Two patients, 1 (50%) male and 1 (50%) female, with mean age of 38 years (range: 16-59 years) underwent endolymphatic thoracic duct stent-graft reconstruction between September 2016 and July 2017. Patients had radiographic left-sided chylothoraces (n = 2) from idiopathic causes (n = 1) and heart transplantation (n = 1). In both (100%) patients, antegrade lymphatic access was used to opacify the thoracic duct after which retrograde access was used for thoracic duct stent-graft placement. Pelvic lymphangiography technical success, antegrade cisterna chyli cannulation technical success, thoracic duct opacification technical success, retrograde thoracic duct access technical success, thoracic duct stent-graft reconstruction technical success, ethiodized oil volume, contrast volume, estimated blood loss, procedure time, fluoroscopy time, radiation dose, clinical success, complications, deaths, and follow-up were recorded. Pelvic lymphangiography, antegrade cisterna chyli cannulation, thoracic duct opacification, retrograde thoracic duct access, and thoracic duct stent-graft reconstruction were technically successful in both (100%) patients. Mean ethiodized oil volume was 8 mL (range: 5-10 mL). Mean contrast volume was 13 mL (range: 5-20 mL). Mean estimated blood loss was 13 mL (range: 10-15 mL). Mean fluoroscopy time was 50.4 min (range: 31.2-69.7 min). Mean dose area product and reference air kerma were 954.4 μGmy 2 (range: 701-1,208 μGmy 2 ) and 83.5 mGy (range: 59-108 mGy), respectively. Chylothorax resolved in both (100%) patients. There were no minor or major complications directly related to the procedure. Thoracic duct stent-graft reconstruction may be a technically successful and safe alternative to thoracic duct embolization, disruption, and surgical ligation for the treatment of chylothorax

Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pressures of patients undergoing cervical, thoracic or lumbar spinal surgery. Prospective study in a tertiary-level university hospital. Sixty-three patients undergoing laminectomy due to diagnoses of tumors or herniated discs were evaluated. Vital capacity, tidal volume, minute ventilation and maximum respiratory pressures were evaluated preoperatively and on the first and second postoperative days. Possible associations between the respiratory variables and the duration of the operation, surgical diagnosis and smoking status were investigated. Vital capacity and maximum inspiratory pressure presented reductions on the first postoperative day (20.9% and 91.6%, respectively) for thoracic surgery (P = 0.01), and maximum expiratory pressure showed reductions on the first postoperative day in cervical surgery patients (15.3%; P = 0.004). The incidence of pulmonary complications was 3.6%. There were reductions in vital capacity and maximum respiratory pressures during the postoperative period in patients undergoing laminectomy. Surgery in the thoracic region was associated with greater reductions in vital capacity and maximum inspiratory pressure, compared with cervical and lumbar surgery. Thus, surgical manipulation of the thoracic region appears to have more influence on pulmonary function and respiratory muscle action.

Full Text Available OBJECTIVE: The main utility of 18-fluorodeoxyglucose positron emission tomography (FDG-PET lies in the staging of lung cancer. However, it can also be used to differentiate indeterminate pulmonary lesions, but its impact on the resection of benign lesions at surgery is unknown. The aim of this study was to compare the prevalence of benign lesions at thoracotomy carried out for suspected lung cancer, before and after the introduction of PET scanning in a large thoracic surgical centre. MATERIALS AND METHODS: We reviewed our prospectively recorded surgical database for all consecutive patients undergoing thoracotomy for suspected or proven lung cancer and compared the prevalence of benign lesions in 2 consecutive 2-year groups, before (group I and after (group II the introduction of FDG-PET scan respectively. RESULTS: Surgical resection was performed on 1233 patients during the study period. The prevalence of benign lesions at surgery in groups I and II was similar (44/626 and 41/607, both 7%, and also in group II between those who underwent FDG-PET scan and the remainder (21/301 and 20/306 respectively, both 7%. In group II, of the 21 patients with benign lesions, who underwent FDG-PET, 19 had a false positive scan (mean standardised uptake value 5.3 [range 2.6-12.7]. Of these, 13 and 4 patients respectively had non-diagnostic bronchoscopy and percutaneous transthoracic lung biopsy pre thoracotomy. There was no difference in the proportion of different benign lesions resected between group I and those with FDG-PET in group II. CONCLUSION: The introduction of FDG-PET scanning has not altered the proportion of patients undergoing thoracotomy for ultimately benign lesions, mainly due to the avidity for the isotope of some non-malignant lesions. Such false positive results need to be considered when patients with unconfirmed lung cancer are contemplated for surgical resection.

Fuentes Valdes, Edelberto; Mojena Morfa, Guillermo; Gonzalez, Miguel Martin

2010-01-01

This is the first case of cardiac re-synchronization therapy (CRT) operated on the ''Hermanos Ameijeiras'' Clinical Surgical Hospital using video-assisted thoracic surgery. Patient is a man aged 67 presenting with a dilated myocardiopathy with severe left ventricular systolic dysfunction. At admission he showed a clinical picture of advanced cardiac insufficiency, thus, we considered the prescription of a CRT. After the failure of the percutaneous therapy for placing a electrode in a epicardiac vein of left ventricle, we decide the minimal invasive surgical approach. The epicardiac electrode implantation by thoracic surgery was a safe procedure without transoperative and postoperative complications. We have knowledge that this is the first time that a video-thoracoscopy in Cardiovascular Surgery is performed in Cuba. (author)

Postoperative unplanned readmissions are costly and decrease patient satisfaction; however, little is known about this complication in pediatric surgery. The purpose of this study was to determine rates and predictors of unplanned readmission in a multi-institutional cohort of pediatric surgical patients. Unplanned 30-day readmissions following general and thoracic surgical procedures in children readmission per 30 person-days were determined to account for varied postoperative length of stay (pLOS). Patients were randomly divided into 70% derivation and 30% validation cohorts which were used for creation and validation of a risk model for readmission. Readmission occurred in 1948 (3.6%) of 54,870 children for a rate of 4.3% per 30 person-days. Adjusted predictors of readmission included hepatobiliary procedures, increased wound class, operative duration, complications, and pLOS. The predictive model discriminated well in the derivation and validation cohorts (AUROC 0.710 and 0.701) with good calibration between observed and expected readmission events in both cohorts (p>.05). Unplanned readmission occurs less frequently in pediatric surgery than what is described in adults, calling into question its use as a quality indicator in this population. Factors that predict readmission including type of procedure, complications, and pLOS can be used to identify at-risk children and develop prevention strategies. III. Copyright © 2017 Elsevier Inc.

Uniportal video assisted thoracic surgery: summary of experience, mini-review and perspectives.

Science.gov (United States)

Migliore, Marcello; Calvo, Damiano; Criscione, Alessandra; Borrata, Francesco

2015-09-01

The uniportal-video assisted thoracic surgery (VATS) technique comprises operations which can be performed with skin incisions ranging from 2 to 8 cm and the manifest result of the introduction of the uniportal lobectomy had made possible to increase rapidly the number of published papers on this subject. Many of the large ensuing literature report incomplete historical information on uniportal VATS, and doubts exist about the indication of uniportal VATS for some thoracic oncologic pathologies. Known limitations have been overcome. On the other hand, the modern thoracic surgical team includes one surgeon, one assistant and a scrub nurse, and it is clear that the new generation of thoracic surgeons need to use the "less" used hand. The new technology which permitted the introduction of the uniportal VATS could influence the future need of thoracic surgeons worldwide.

Full Text Available Background: Robotic surgery is an alternative to minimally invasive surgery. The aim of this study was to report on current trends in robotic thoracic and cardiovascular surgical techniques in Korea. Methods: Data from the National Evidence-based Healthcare Collaborating Agency (NECA between January 2006 and June 2012 were used in this study, including a total of 932 cases of robotic surgeries reported to NECA. The annual trends in the case volume, indications for robotic surgery, and distribution by hospitals and surgeons were analyzed in this study. Results: Of the 932 cases, 591 (63% were thoracic operations and 340 (37% were cardiac operations. The case number increased explosively in 2007 and 2008. However, the rate of increase regained a steady state after 2011. The main indications for robotic thoracic surgery were pulmonary disease (n=271, 46%, esophageal disease (n=199, 34%, and mediastinal disease (n=117, 20%. The main indications for robotic cardiac surgery were valvular heart disease (n=228, 67%, atrial septal defect (n=79, 23%, and cardiac myxoma (n=27, 8%. Robotic thoracic and cardiovascular surgeries were performed in 19 hospitals. Three large volume hospitals performed 94% of the case volume of robotic cardiac surgery and 74% of robotic thoracic surgery. Centralization of robotic operation was significantly (p＜0.0001 more common in cardiac surgery than in thoracic surgery. A total of 39 surgeons performed robotic surgeries. However, only 27% of cardiac surgeons and 23% of thoracic surgeons performed more than 10 cases of robotic surgery. Conclusion: Trend analysis of robotic and cardiovascular operations demonstrated a gradual increase in the surgical volume in Korea. Meanwhile, centralization of surgical cases toward specific surgeons in specific hospitals was observed.

Recent clinical innovations in thoracic surgery in Hong Kong.

The concept of personalized medicine, which aims to provide patients with targeted therapies while greatly reducing surgical trauma, is gaining popularity among Asian clinicians. Single port video-assisted thoracic surgery (VATS) has rapidly gained popularity in Hong Kong for major lung resections, despite bringing new challenges such as interference between surgical instruments and insertion of the optical source through a single incision. Novel types of endocutters and thoracoscopes can help reduce the difficulties commonly encountered during single-port VATS. Our region has been the testing ground and has led the development of many of these innovations. Performing VATS, in particular single-port VATS in hybrid operating theatre helps to localise small pulmonary lesions with real-time images, thus increasing surgical accuracy and pushes the boundaries in treating subcentimeter diseases. Such approach may be assisted by use of electromagnetic navigational bronchoscopy in the same setting. In addition, sublobar resection can also be more individualised according to pathologic tumour subtype that require rapid intraoperative diagnostic test to guide appropriate surgical therapy. A focus on technology and innovation for large tumours that require chest wall resection and reconstructions have also been on going, with new materials and prostheses that may be tailored to each individual needs. The current paper reviews the literature pertaining to the above topics and discusses recent related innovations in Hong Kong, highlighting the study results and future perspectives.

The role of wet lab in thoracic surgery.

Bedetti, Benedetta; Schnorr, Philipp; Schmidt, Joachim; Scarci, Marco

2017-01-01

During the last three decades, minimally invasive surgery has become common practice in all kinds of surgical disciplines and, in Thoracic Surgery, the minimally invasive approach is recommended as the treatment of choice for early-stage non-small cell lung cancer. Nevertheless, all over the world a large number of lobectomies is still performed by conventional open thoracotomy and not as video-assisted thoracic surgery (VATS), which shows the need of a proper training for this technique. Development and improvement of surgical skills are not only challenging and time-consuming components of the training curriculum for resident or fellow surgeons, but also for more experienced consultants learning new techniques. The rapid evolution of medical technologies like VATS or robotic surgery requires an evolution of the existing educational models to improve cognitive and procedural skills before reaching the operating room in order to increase patient safety. Nowadays, in the Thoracic Surgery field, there is a wide range of simulation-based training methods for surgeons starting or wanting to improve their learning curve in VATS. Aim is to overcome the learning curve required to successfully master this new technique in a brief time. In general, the basic difference between the various learning techniques is the distinction between "dry" and "wet" lab modules, which mainly reflects the use of synthetic or animal-model-based materials. Wet lab trainings can be further sub-divided into in vivo modules, where living anaesthetized animals are used, and ex vivo modules, where only animal tissues serve as basis of the simulation-based training method. In the literature, the role of wet lab in Thoracic Surgery is still debated.

BACKGROUND: Road deaths fell initially after the introduction of the penalty points but despite this, the rate of spinal injuries remained unchanged. AIMS: We report a patient with a dramatic spinal injury, though without neurological deficit. We discuss the classification, management and economic impact of these injuries. METHODS: We describe the management of a patient with a comminuted thoracic spinal fracture without neurological injury. We conducted a literature review with regard to the availability of literature of the management of these injuries. RESULTS: This 17-year-old female was managed surgically and had a good functional outcome. There is no clear consensus in the published literature on the management of these injuries. CONCLUSIONS: Comminuted thoracic spinal factures are potentially devastating. Such a patient presents challenges in determining the appropriate treatment.

OBJECTIVE Pedicle screw fixation is a technique widely used to treat conditions ranging from spine deformity to fracture stabilization. Pedicle screws have been used traditionally in the lumbar spine; however, they are now being used with increasing frequency in the thoracic spine as a more favorable alternative to hooks, wires, or cables. Although safety concerns, such as the incidence of adjacent-segment disease (ASD) after cervical and lumbar fusions, have been reported, such issues in the thoracic spine have yet to be addressed thoroughly. Here, the authors review the literature on ASD after thoracic pedicle screw fixation and report their own experience specifically involving the use of pedicle screws in the thoracic spine. METHODS Select references from online databases, such as PubMed (provided by the US National Library of Medicine at the National Institutes of Health), were used to survey the literature concerning ASD after thoracic pedicle screw fixation. To include the authors' experience at Rutgers New Jersey Medical School, a retrospective review of a prospectively maintained database was performed to determine the incidence of complications over a 13-year period in 123 consecutive adult patients who underwent thoracic pedicle screw fixation. Children, pregnant or lactating women, and prisoners were excluded from the review. By comparing preoperative and postoperative radiographic images, the occurrence of thoracic ASD and disease within the surgical construct was determined. RESULTS Definitive radiographic fusion was detected in 115 (93.5%) patients. Seven incidences of instrumentation failure and 8 lucencies surrounding the screws were observed. One patient was observed to have ASD of the thoracic spine. The mean follow-up duration was 50 months. CONCLUSIONS This long-term radiographic evaluation revealed the use of pedicle screws for thoracic fixation to be an effective stabilization modality. In particular, ASD seems to be less of a problem in the

Muscle rupture is rarely treated surgically. Few reports of good outcomes after muscular suture have been published. Usually, muscular lesions or partial ruptures heal with few side effects or result in total recovery. We report a case of an athlete who was treated surgically to repair a total muscular rupture in the pectoralis major muscle. After 6 months, the athlete returned to competitive practice. After a 2-year follow-up, the athlete still competes in skateboard championships. PMID:25716033

Biomechanical Evaluation of the MACSTL Internal Fixator for Thoracic Spinal Stabilisation

Directory of Open Access Journals (Sweden)

2008-01-01

Full Text Available Unstable fractures of the thoracic spine in humans represent a serious social and economic issue. They may lead to persistent consequences and chronic disease. The anatomical and biomechanical characteristics of the thoracic spine are different from all the other spinal parts due to its higher mobility. The vertebrae of the chest area are less mobile, conferring a higher degree of rigidity to the spine. To destabilize this relatively rigid system, a considerable force is necessary. The treatment of unstable spinal fractures is solely surgical. The decompression of the spinal canal with reposition and stabilisation of the fracture is indicated urgently. This intervention is performed mostly from the posterior approach in the first phase. However, the anterior spinal column is the structure responsible for the stability of the spine. Therefore, the recent advances in spine surgery focus on this area of expertise. For this reason, we carried out a bio-mechanical study aimed at assessing the effectiveness of two surgical tactics used. The study consisted of comparative experiments performed by computer-aided device on segments of pig cadavers (n = 5. The experiment involved a comparison of segments of the thoracic spine under the following conditions: an anatomically intact segment, a spine segment with an artificially created anterior instability, and a segment with an applied internal fixator. The experiment compared the mechanical characteristics of these segments. The experiment has demonstrated that after application of the internal fixator used for stabilisation of the injured anterior spinal column at defined pre-loading of 200 N, the stability of damaged spinal segment in torsion increased twofold. It was also verified that sufficient stability can be ensured using the Modular Anterior Construct System (MACSTL implant for ventral stabilisation of thoracic spine unstable injuries. Endoscopic application of this implant represents an

Full Text Available Background: The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. Methods: From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. Results: Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7% of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. Conclusion: Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

Purpose. Traumatic rupture of the thoracic aorta secondary to blunt chest trauma is a life-threatening emergency and a common cause of death, usually following violent collisions. The objective of this retrospective report was to evaluate the efficacy of endovascular treatment of thoracic aortic disruptions with a single commercially available stent-graft. Methods. Nine men (mean age 29.5 years) were admitted to our institution between January 2003 and January 2006 due to blunt aortic trauma following violent motor vehicle collisions. Plain chest radiography, spiral computed tomography, aortography, and transesophageal echocardiography were used for diagnostic purposes in all cases. All patients were diagnosed with contained extramural thoracic aortic hematomas, secondary to aortic disruption. One patient was also diagnosed with a traumatic thoracic aortic dissection, secondary to blunt trauma. All subjects were poor surgical candidates, due to major injuries such as multiple bone fractures, abdominal hematomas, and pulmonary contusions. All repairs were performed using the EndoFit (LeMaitre Vascular) stent-graft. Results. Complete exclusion of the traumatic aortic disruption and pseudoaneurysm was achieved and verified at intraoperative arteriography and on CT scans, within 10 days of the repair in all patients. In 1 case the deployment of a second cuff was necessary due to a secondary endoleak. In 2 cases the left subclavian artery was occluded to achieve adequate graft fixation. No procedure-related deaths have occurred and no cardiac or peripheral vascular complications were observed within the 12 months (range 8-16 months) follow-up. Conclusions. This is the first time the EndoFit graft has been utilized in the treatment of thoracic aortic disruptions secondary to chest trauma. The repair of such pathologies is technically feasible and early follow-up results are promising

Full Text Available High speed vehicles, drug abuse, alcohol and easy availability of handguns are the main reasons of increasing number of trauma especially thoracic trauma. Anaesthesiologist plays an important role in the management of extensive thoracic trauma. Thoracic trauma, penetrating or blunt, may cause damage to organs suspended in thorax viz. pleura, lungs, heart, great vessels, trachea and oesophagus. It may lead to pneumothorax, cardiac tamponade or life threatening haemorrhage. With aggressive care and management of these factors, majority of patients can survive and return to normal life.

Bjurlin, Marc A

2012-02-01

Endovascular stent graft treatment of acute thoracic aortic transections is an encouraging minimally invasive alternative to open surgical repair. Between 2006 and 2008, 16 patients with acute thoracic aortic transections underwent evaluation at our institution. Seven patients who were treated with an endovascular stent graft were reviewed. The mean Glasgow Coma Score was 13.0, probability of survival was .89, and median injury severity score was 32. The mean number of intensive care unit days was 7.7, mean number of ventilator support days was 5.4, and hospital length of stay was 10 days. Mean blood loss was 285 mL, and operative time was 143 minutes. Overall mortality was 14%. Procedure complications were a bleeding arteriotomy site and an endoleak. Endovascular treatment of traumatic thoracic aortic transections appears to demonstrate superior results with respect to mortality, blood loss, operative time, paraplegia, and procedure-related complications when compared with open surgical repair literature.

Multicenter retrospective case series. To determine the rate of thoracic duct injury during cervical spine operations. A retrospective case series study was conducted among 21 high-volume surgical centers to identify instances of thoracic duct injury during anterior cervical spine surgery. Staff at each center abstracted data for each identified case into case report forms. All case report forms were collected by the AOSpine North America Clinical Research Network Methodological Core for data processing, cleaning, and analysis. Of a total of 9591 patients reviewed that underwent cervical spine surgery, 2 (0.02%) incurred iatrogenic injury to the thoracic duct. Both patients underwent a left-sided anterior cervical discectomy and fusion. The interruption of the thoracic duct was addressed intraoperatively in one patient with no residual postoperative effects. The second individual developed a chylous fluid collection approximately 2 months after the operation that required drainage via needle aspiration. Damage to the thoracic duct during cervical spine surgery is a relatively rare occurrence. Rapid identification of the disruption of this lymphatic vessel is critical to minimize deleterious effects of this complication.

Postoperative thoracic hemorrhage after right upper lobectomy with thoracic wall resection during rivaroxaban anticoagulant therapy for deep leg vein thrombosis: A case report

Directory of Open Access Journals (Sweden)

Taiji Kuwata

Full Text Available Introduction: Postoperative pulmonary embolism (PE is the one of the most important complications after thoracic surgery. This complicatin after the surgery is often treated by new anticoaglant drug, such as rivaroxaban, which dose not need to the monitoring of blood coaglation system. We experienced postoperative bleeding case during anticoaglant therapy using rivaroxaban. Presentation of case: The patient underwent a right upper lobectomy with lung and chest wall resection for lung cancer. On postoperative day (POD 10, we started to use rivaroxaban to treat the deep vein thrombosis (DVT. Four days after starting the rivaroxaban treatment, severe surgical site hemorrhage occurred, which led to the need for the infusion of concentrated red cells (CRC. After stopping the rivaroxaban, the thoracic bleeding ceased. Because the event occurred so long after the surgery, and because the bleeding stopped after withdrawal of treatment, we believe that rivaroxaban induced the thoracic bleeding. Conclusion: Some reports in the field of orthopedics (Turpie et al., 2009 have noted that rivarxaban is effective to prevent postoperative DVT. However, there were few reports that invied the attention to postoperative bleeding be induced by rivarxaban. Thus, we describe this case in order to alert clinicians to the potential bleeding risks associated with the admistration of rivaroxaban postoperatively.

Extracorporeal membrane oxygenation (ECMO) for respiratory support is increasingly used in intensive care units (ICU), but rarely during thoracic surgical procedures outside the transplantation setting. ECMO can be an alternative to cardiopulmonary bypass for major trachea-bronchial surgery and single-lung procedures without in-field ventilation. Our aim was to evaluate the intraoperative use of ECMO as respiratory support in thoracic surgery: benefits, indications and complications. This was a multicentre retrospective study (questionnaire) of use of ECMO as respiratory support during the thoracic surgical procedure. Lung transplantation and lung resection for tumour invading the great vessels and/or the left atrium were excluded, because they concern respiratory and circulatory support. From March 2009 to September 2012, 17 of the 34 centres in France applied ECMO within veno-venous (VV) (n=20) or veno-arterial (VA) (n=16) indications in 36 patients. Ten VA ECMO were performed with peripheral cannulation and 6 with central cannulation; all VV ECMO were achieved through peripheral cannulation. Group 1 (total respiratory support) was composed of 28 patients without mechanical ventilation, involving 23 tracheo-bronchial and 5 single-lung procedures. Group 2 (partial respiratory support) was made up of 5 patients with respiratory insufficiency. Group 3 was made up of 3 patients who underwent thoracic surgery in a setting of acute respiratory distress syndrome (ARDS) with preoperative ECMO. Mortality at 30 days in Groups 1, 2 and 3 was 7, 40 and 67%, respectively (P<0.05). In Group 1, ECMO was weaned intraoperatively or within 24 h in 75% of patients. In Group 2, ECMO was weaned in ICU over several days. In Group 1, 2 patients with VA support were converted to VV support for chronic respiratory indications. Bleeding was the major complication with 17% of patients requiring return to theatre for haemostasis. There were two cannulation-related complications (6%). VV or

The frequently encountered thoracic trauma in surgical emergencies is a major cause of mortality and morbidity. Eighty percent of thoracic trauma can be managed by simple insertion of tube thoracostomy. Though guidelines for insertion are comprehensively explained in literature, an ideal algorithm for discontinuation is not available. A standard and safe defined protocol would eliminate hesitancy in confident removal among general surgeons. The objective of this study was to determine role of clamping trial prior to removal in terms of frequency of recurrent pneumothorax. Methods: This study was conducted in department of Surgery Combined military hospital/Military Hospital Rawalpindi from April 2013 to March 2014. Total 180 patients with blunt or penetrating thoracic trauma were included in the study. Chest tube (28-36 Fr) was inserted in Trauma centre under strict asepsis. Tubes were then connected to under water seal for minimum six hours. Patients were randomly divided in two equal groups (90 in each). In Group A, Clamping trial was given before attempting removal while in Group B, tube was removed immediately without clamping trial. Patients of both groups were observed two hourly for development of recurrent pneumothorax. Data was analysed using SPSS-18. Results: The comparison of frequency of recurrent pneumothorax in Group A (9 patients, 10%) and in Group B (4 patients, 4.5%) was not found to be statistically significant. (p-value 2.073). Conclusion: Clamping trial is unnecessary prior to removal of tube thoracostomy in blunt and penetrating non-cardiac thoracic trauma in terms of recurrent pneumothorax. (author)

Background In some patients, local surgery-related complications are diagnosed many years after surgery for aortic coarctation. The purposes of this study were: (1) to systematically evaluate asymptomatic adults after Dacron patch repair in childhood, (2) to estimate the formation rate of secondary thoracic aortic aneurysms (TAAs) and (3) to assess outcomes after intravascular treatment for TAAs. Methods This study involved 37 asymptomatic patients (26 female and 11 male) who underwent surgical repair of aortic coarctation in the childhood. After they had reached adolescence, patients with secondary TAAs were referred to endovascular repair. Results Follow-up studies revealed TAA in seven cases (19%) (including six with the gothic type of the aortic arch) and mild recoarctation in other six (16%). Six of the TAA patients were treated with stentgrafts, but one refused to undergo an endovascular procedure. In three cases, stengrafts covered the left subclavian artery (LSA), in another the graft was implanted distally to the LSA. In two individuals, elective hybrid procedures were performed with surgical bypass to the supraaortic arteries followed by stengraft implantation. All subjects survived the secondary procedures. One patient developed type Ia endoleak after stentgraft implantation that was eventually treated with a debranching procedure. Conclusions The long-term course of clinically asymptomatic patients after coarctation patch repair is not uncommonly complicated by formation of TAAs (particularly in individuals with the gothic pattern of the aortic arch) that can be treated effectively with stentgrafts. However, in some patients hybrid procedures may be necessary. PMID:24386233

Retrospective case series of surgically treated adolescent patients with scoliosis. To assess the prevalence and independent risk factors for postoperative shoulder imbalance in surgically treated adolescent patients with idiopathic scoliosis. Despite recent reports that have identified risk factors for postoperative shoulder imbalance, the relative risks remain unclear. A retrospective review of 85 consecutive patients treated with thoracic fusion with a minimum 2-year follow-up (mean, 3.1 yr) was conducted to investigate the patient radiographical measurements and demographics. Shoulder height difference (SHD) was measured as the graded height difference of the soft tissue shadows. A SHD more than 2 cm indicated an unbalanced shoulder. Patient demographics and radiographical data were studied to determine risk factors for postoperative SHD. The potential risk factors included age, sex, Risser sign, Cobb angle, flexibility, and apical vertebral rotation (AVR) of the main curve, upper-instrumented vertebra level, SHD, and clavicle chest cage angle difference (CCAD). Univariate and multivariate logistic regression analyses were performed to determine the independent risk factors for postoperative shoulder imbalance. Of the 85 patients, 21 patients presented postoperative shoulder imbalance. The univariate analysis indicated age, Risser sign, Cobb angle of the main curve, AVR of the main curve, and CCAD as risk factors, but the multivariate logistic regression analysis showed that only AVR of the main curve and CCAD were independent risk factors for postoperative shoulder imbalance (AVR, P = 0.04, odds ratio (OR): 3.54; CCAD, P = 0.01, OR: 5.10). Postoperative shoulder imbalance was observed in 25% of the surgically treated adolescent patients. The CCAD and AVR of the main thoracic curve were independent risk factors for postoperative shoulder imbalance in surgically treated patients with adolescent idiopathic scoliosis. The significant correlation between CCAD and

Full Text Available The purpose of the study is to analyze and systematize main causes of secondary spine deformations forming in patients who had operations due to thoracic and lumbar spine damages. Material and Methods. The analysis of poor surgical results of 155 patients previously operated due to various thoracic and lumbar spine damages has been conducted. All patients had complications associated with secondary spinal column deformations at various time after the intervention. Standard investigation included the analysis of patients' complaints, their previous history, somatic, neurological and orthopedic status. Results. The intensity of spinal column deformation was defined due to the character and level of primary trauma structurally characterized predominantly by unstable damages. However as it has been found in this research the main cause of this complicated pathology lied in the number of tactical and technical pitfalls of primary surgical treatment. Conclusion. Surgical operations due to secondary post-traumatic deformations in most cases are laborious and are accompanied by significant surgical trauma therefore systematization and analysis of the main causes of poor results of primary spine surgery may contribute to the preventive treatment of this type of pathology.

Multidisciplinary Treatment Approach for Prosthetic Vascular Graft Infection in the Thoracic Aortic Area

Science.gov (United States)

Watanabe, Yoshinori

2015-01-01

Prosthetic vascular graft infection in the thoracic aortic area is a rare but serious complication. Adequate management of the complication is essential to increase the chance of success of open surgery. While surgical site infection is suggested as the root cause of the complication, it is also related to decreased host tolerance, especially as found in elderly patients. The handling of prosthetic vascular graft infection has been widely discussed to date. This paper mainly provides a summary of literature reports published within the past 5 years to discuss issues related to multidisciplinary treatment approaches, including surgical site infection, timing of onset, diagnostic methods, causative pathogens, auxiliary diagnostic methods, antibiotic treatment, anti-infective structures of vascular prostheses, surgical treatment, treatment strategy against infectious aortic aneurysms, future surgical treatment, postoperative systemic therapy, and antimicrobial stewardship. A thorough understanding of these issues will enable us to prevent prosthetic vascular graft infection in the thoracic aortic area as far as possible. In the event of its occurrence, the early introduction of appropriate treatment is expected to cure the disease without worsening of the underlying pathological condition. PMID:26356686

We have previously reported on the importance of appropriate robot-arm settings and replacement of instrument ports in robot-assisted thoracic surgery, because the thoracic cavity requires a large space to access all lesions in various areas of the thoracic cavity from the apex to the diaphragm and mediastinum and the chest wall.1–3 Moreover, it can be difficult to manipulate the da Vinci Surgical System using only arms No. 1 and No. 2 depending on the tumor location. However, arm No. 3 is usually positioned on the same side as arm No. 2, and sometimes it is only used as an assisting-arm to avoid conflict with other arms (Fig. 1). In this report, we show how robot-arm No. 3 can be used with maximum effectiveness in da Vinci-assisted thoracic surgery. PMID:26011219

Full Text Available ABSTRACT Objective: to analyze the National Cancer Institute Abdominopelvic Division (INCA / MS/HC I initial experience with thoraco-laparoscopic esophagectomy with thoracic stage in prone position. Methods: we studied 19 consecutive thoraco-laparoscopic esophagectomies from may 2012 to august 2014, including ten patients with squamous cells carcinoma (five of the middle third and five of the lower third and nine cases of gastroesophageal junction adenocarcinoma (six Siewert I and three Siewert II. All procedures were initiated by the prone thoracic stage. Results: There were minimal blood loss, optimal mediastinal visualization, oncological radicality and no conversions. Surgical morbidity was 42 %, most being minor complications (58% Clavien I or II, with few related to the technique. The most common complication was cervical anastomotic leak (37%, with a low anastomotic stricture rate (two stenosis: 10.53%. We had one (5.3% surgical related death, due to a gastric tube`s mediastinal leak, treated by open reoperation and neck diversion. The median Intensive Care Unit stay and hospital stay were two and 12 days, respectively. The mean thoracoscopic stage duration was 77 min. Thirteen patients received neoadjuvant treatment (five squamous cells carcinoma and eight gastroesophageal adenocarcinomas. The average lymph node sample had 16.4 lymph nodes per patient and 22.67 when separately analyzing patients without neoadjuvant treatment. Conclusion: the thoraco-laparoscopic approach was a safe technique in the surgical treatment of esophageal cancer, with a good lymph node sampling.

Thoracic vasculitis presenting as surgical problems.

LENUS (Irish Health Repository)

Jansen, Michael

2010-01-01

We present four patients with vasculitis manifesting with unusual clinical or pathological features, generating surgical problems. Two cases presented with pulmonary hypertension, with investigations and radiological evidence prompting clinical suspicion of pulmonary thrombo-embolic disease. First case, with an antecedant history of Wegener\\'s granulomatosis (WG), demonstrated following "embolectomy", WG involving the large pulmonary elastic arteries. The second case of inoperable "pulmonary thrombo-embolic disease" was subsequently found at limited post mortem to have giant cell arteritis, which affected widespread small peripheral pulmonary arterial vessels. The other two cases were of aortitis occurring in the background of immune-mediated disease, which had been treated with aggressive immunosuppression regimens. The first of these was a case of Cogan\\'s syndrome complicated by descending aortitis, a rarely reported phenomenon, with co-existent acute endocarditis of the aortic valve leaflets. Most cases of endocarditis in this context occur secondary to and in continuity with ascending aortitis. That this case, and a case of ascending aortitis occurring in the context of relapsing polychondritis occurred in the face of aggressive immunosuppression with an apparent clinical response, underscores the need to not accept a clinical picture at face value. This has implications for clinical management, particularly in the follow-up of surgical prosthetic devices such as grafts which may be used in these cases. All four cases emphasise the continued importance of histology and the post-mortem examination in elucidating previously undetected or unsuspected disease.

2015-01-01

Full Text Available Background. Thoracic epidural catheters provide the best quality postoperative pain relief for major abdominal and thoracic surgical procedures, but placement is one of the most challenging procedures in the repertoire of an anesthesiologist. Most patients presenting for a procedure that would benefit from a thoracic epidural catheter have already had high resolution imaging that may be useful to assist placement of a catheter. Methods. This retrospective study used data from 168 patients to examine the association and predictive power of epidural-skin distance (ESD on computed tomography (CT to determine loss of resistance depth acquired during epidural placement. Additionally, the ability of anesthesiologists to measure this distance was compared to a radiologist, who specializes in spine imaging. Results. There was a strong association between CT measurement and loss of resistance depth (P35 changed this relationship (P=0.007. The ability of anesthesiologists to make CT measurements was similar to a gold standard radiologist (all individual ICCs>0.9. Conclusions. Overall, this study supports the examination of a recent CT scan to aid in the placement of a thoracic epidural catheter. Making use of these scans may lead to faster epidural placements, fewer accidental dural punctures, and better epidural blockade.

Thrombus formation in an atherosclerotic or aneurysmal descending thoracic aorta is a well-described, frequently encountered vascular condition. In comparison, thrombus formation in a normal-appearing descending thoracic aorta is reported far less often. We describe the case of a 46-year-old woman who had splenic and renal infarctions secondary to embolic showers from a large, mobile thrombus in a morphologically normal proximal descending thoracic aorta. After the patient underwent anticoagulation, stent-grafting, and surgical bypass to correct an arterial blockage caused by the stent-graft, she resumed a relatively normal life. In contrast with other cases of a thrombotic but normal-appearing descending thoracic aorta, this patient had no known malignancy or systemic coagulative disorders; her sole risk factor was chronic smoking. We discuss our patient's case and review the relevant medical literature, focusing on the effect of smoking on coagulation physiology. PMID:24391341

2012-01-01

Background and purpose: The incidence of retrosternal goiter (Rg) varies from 2% to 26% of all thyroidectomies, depending on the defining criteria . There are no clear guidelines to identify patients that require an intrathoracic approach. So, we tried to correlate, between the size and/ or anatomical site of the RSG based on preoperative CT findings and the surgical approaches used, aiming at defining those patients with RSG who are in need for thoracic approach. Patients and methods: Out of 1481 patients underwent thyroidectomy at the National Cancer Institute (NCI), Cairo University, between January 2000 and December 2009, only 73 (4.93%) of them had retrosternal extension. Demographic, clinical, operative, anatomical, and pathological data of patients with RSG were recorded and analyzed. Results: The intraoperative extension of the goiter correlated with the extension seen in the CT in all except two patients. Laterality and longitudinal extension found in preoperative CT, correlated well with the surgical findings. The approach used was cervical in 66 cases (90.4%); combined approach in six patients (8.2%). Pure thoracic (full sternotomy) was used alone in one case (1.4%). Extension of the RSG down to or below the arch was associated with an increased risk of using a thoracic approach p< 0.0001. Conclusion: Preoperative CT, can be used effectively to guide the indications for using a thoracic approach. Reaching the aortic arch or beyond and loss of fat planes in CT, recurrent and malignant disease, are significant risk factors for using a thoracic approach.

Three cases of rare location spondylitis tuberculosis are reported, each in atlantoaxial, cervico-thoracic junction,and sacral. The complaints were aweakness of motoric strength and local back pain. Patients’thoracal x-ray was normal, there was no complaint of acough, PCR forTB was early diagnostic and positive in all three cases, HIV negative, intraoperative tissue samplings were sent for histopathology examination and the results showed thespecific inflammatory process. Lesions were evaluated with computer tomography and/or MRI imaging.Preoperative TB regimens therapy were given for 2 weeks and continued for nine months. The surgical procedurewas done in all cases with excellent improvement of symptoms and motoric strength. In our institution,25 cases of total TB spondylitis were performed in 2 years, only 1 case eachwas found in atlanto-axial, cervico-thoracic and sacral.

Acute Paraparesis Caused by a Giant Cell Tumor of the Thoracic Spine

Liang-Chun Chao

2014-12-01

Full Text Available Giant cell tumor (GCT is a benign but locally aggressive skeletal neoplasm of young adults. GCT located in the spine is relatively rare and may need a combination of surgical and adjunctive therapies. Here we present a patient who had intermittent thoracic back pain for two weeks and experienced an acute episode of decreased muscle power of both lower limbs. Magnetic resonance (MR imaging examinations of the thoracic spine revealed that the patient had severe spinal canal compression caused by pathological fracture due to a tumor within the seventh thoracic vertebra. She underwent an emergent surgical intervention for total removal of the tumor and spinal reconstruction with autologous rib grafts and instruments. Postoperatively, the patient made an uneventful recovery of muscle power of bilateral lower limbs. She subsequently received adjuvant radiotherapy. In a follow-up period of 36 months, the patient had no clinical or radiological evidence of tumor recurrence. Even though spinal location for GCT is a rare event, it should be included in the differential diagnosis in patients with osteolytic lesions or pathological fractures of the vertebra, especially in young female patients sustaining no trauma who had a clinical history of persistent low back pain.

Treating thoracic infective spondylodiscitis with anterior surgical approaches carry a relatively high risk of perioperative and postoperative complications. Posterior approaches have been reported to result in lower complication rates than anterior procedures, but more evidence is needed to demonstrate the safety and efficacy of 1-stage posterior approaches for treating infectious thoracic spondylodiscitis.Preoperative and postoperative clinical data, of 18 patients who underwent 2 types of 1-stage posterior procedures, costotransversectomy and transforaminal thoracic interbody debridement and fusion and 7 patients who underwent anterior debridement and reconstruction with posterior instrumentation, were retrospectively assessed.The clinical outcomes of patients treated with 1-stage posterior approaches were generally good, with good infection control, back pain relief, kyphotic angle correction, and either partial or solid union for fusion status. Furthermore, they achieved shorter surgical time, fewer postoperative complications, and shorter hospital stay than the patients underwent anterior debridement with posterior instrumentation.The results suggested that treating thoracic spondylodiscitis with a single-stage posterior approach might prevent postoperative complications and avoid respiratory problems associated with anterior approaches. Single-stage posterior approaches would be recommended for thoracic spine infection, especially for patients with medical comorbidities.

Full Text Available An ectopic kidney is a common developmental anomaly of the urinary system. However, the thoracic kidney (TK is the rarest state form of an aberrant kidney. The aim of this case report is defining the symptoms in TK diagnosis and constructing a treatment model will promote the best outcomes. These patients come to the physician with the various symptoms, and they could be diagnosed incidentally. In our case, we describe 40 years female patient with severe respiratory problems and upper back pain. In the pulmonary clinic, suspected mass was diagnosed with chest X-ray, and computerized tomography detected nontraumatic nonhernia associated, a truly ectopic TK. Moreover, the thoracic surgeon and urologist team decided to exploration and reconstructed the right ectopic kidney. The 1st month of the control of patient symptoms was disappeared. Overall, TK should be kept in mind in the differential diagnosis of thoracic tumors. Surgical exploration and reconstruction should be thought in patients who have severe respiratory symptoms.

Pitfalls in penetrating thoracic trauma (lessons we learned the hard way...).

Science.gov (United States)

Degiannis, Elias; Zinn, Richard Joseph

2008-10-01

The majority of patients with penetrating thoracic trauma are managed non-operatively. Those requiring surgery usually go to theater with physiological instability. The critical condition of these patients coupled with the rarity of penetrating thoracic trauma in most European countries makes their surgical management challenging for the occasional trauma surgeon, who is usually trained as a general surgeon. Most general surgeons have a general knowledge of basic cardiothoracic operative surgery, knowledge originating from their training years and possibly enhanced by reading operative surgery textbooks. Unfortunately, the details included in most of these books are not extensive enough to provide him with enough armamentaria to tackle the difficult case. In this anatomical region, their operative dexterity and knowledge cannot be compared to that of their cardiothoracic colleagues, something that is taken for granted in their cardiothoracic trauma textbooks. Techniques that are considered basic and easy by the cardiothoracic surgeons can be unfamiliar and difficult to general surgeons. Knowing the danger points and the pitfalls that will be encountered in cardiothoracic trauma surgery will help them to avoid intraoperative errors and improve patient outcome. The purpose of this manuscript is to highlight the commonly encountered pitfalls by trauma surgeons operating on penetrating trauma to the chest.

Full Text Available Background. Acquired elevation of the diaphragm is mostly the result of phrenic nerve paralysis, some of thoracic and abdominal patological states, and also some of neuromuscular diseases. Surgical treatment is rarely performed and is indicated when lung compression produces disabilitating dyspnea, and includes plication of diaphragm. The goal of this case report has been to show completely documented diagnostic procedures and surgical treatment one of rare pathological condition. Case report. A 62-year-old patient was admitted to our clinic because of surgical treatment of the enormous elevation of the left hemidiaphragm. After thoracotomy and plication of the bulging diaphragm, lung compression did not exist any more and mediastinum went back in the normal position. Conclusion. Elevation of the diaphragm rarely demands surgical correction. When it is complicated with lung compression and disabilitating dyspnea, surgical treatment has extremely useful functional effect.

We describe the optimal protocol of magnetic resonance-thoracic ductography (MRTD) and provide examples of thoracic ducts (TD) and various anomalies. The anatomical pathway of the TD was analyzed based on embryological considerations. A total of 78 subjects, consisting of noncancer adults and patients with esophageal cancer and lung cancer, were enrolled. The MRTD protocol included a long echo time and was based on emphasizing signals from the liquid fraction and suppressing other signals, based on the principle that lymph flow through the TD appears hyperintense on T2-weighted images. The TD configuration was classified into nine types based on location [right and/or left side(s) of the descending aorta] and outflow [right and/or left venous angle(s)]. MRTD was conducted in 78 patients, and the three-dimensional reconstruction was considered to provide excellent view of the TD in 69 patients, segmentalization of TD in 4, and a poor view of the TD in 5. MRTD achieved a visualization rate of 94%. Most of the patients had a right-side TD that flowed into the left venous angle. Major configuration variations were noted in 14% of cases. Minor anomalies, such as divergence and meandering, were frequently seen. MRTD allows noninvasive evaluation of TD and can be used to identify TD configuration. Thus, this technique is considered to contribute positively to safer performance of thoracic surgery. (author)

Background. Inconsistent accuracies of CT-guided thoracic spinal biopsies have been reported in previous studies. Purpose. To determine the accuracy of CT-guided thoracic spinal biopsy, to compare the results with those previously reported, and to determine if there are any factors that influence the accuracy of CT-guided thoracic spinal biopsy. Material and Methods. In total, 158 consecutive CT-guided percutaneous thoracic spine procedures (performed at the Dept. of Spinal Surgery, Xian Red Cross Hospital between April 2000 and July 2010) were reviewed. The 158 lesions were categorized by location and radiographic features. Pathological and clinical follow-up were used to determine accuracy. Results. The diagnostic accuracy of CT-guided thoracic spinal biopsy was 90.5% overall. Biopsy of metastatic bone disease (98.2%) was significantly more accurate than biopsies of primary tumors (80.9%) and of hematological malignancies (47.0%) (P < 0.05 and P < 0.005, respectively). The diagnostic accuracy of CT-guided thoracic spinal biopsy was significantly higher for the lower thoracic spine (97.6%) than for the middle (90.0%) or upper thoracic spine (80.4%) (P < 0.05 and P < 0.025, respectively). The diagnostic accuracy was significantly higher for lytic lesions (96.4%) than for sclerotic lesions (81.3%) (P < 0.010). The accuracy of biopsies performed using the transpedicular approach (91.0%) was not significantly different from that of biopsies performed using posterolateral approaches (91.5%) (0.25 < P < 0.5). Conclusion. Percutaneous CT-guided thoracic spinal biopsy is a viable alternative to open surgical biopsy. The diagnostic accuracy was not affected by any of the variables except for lesion level, histology, and radiographic features

Background. Inconsistent accuracies of CT-guided thoracic spinal biopsies have been reported in previous studies. Purpose. To determine the accuracy of CT-guided thoracic spinal biopsy, to compare the results with those previously reported, and to determine if there are any factors that influence the accuracy of CT-guided thoracic spinal biopsy. Material and Methods. In total, 158 consecutive CT-guided percutaneous thoracic spine procedures (performed at the Dept. of Spinal Surgery, Xian Red Cross Hospital between April 2000 and July 2010) were reviewed. The 158 lesions were categorized by location and radiographic features. Pathological and clinical follow-up were used to determine accuracy. Results. The diagnostic accuracy of CT-guided thoracic spinal biopsy was 90.5% overall. Biopsy of metastatic bone disease (98.2%) was significantly more accurate than biopsies of primary tumors (80.9%) and of hematological malignancies (47.0%) (P < 0.05 and P < 0.005, respectively). The diagnostic accuracy of CT-guided thoracic spinal biopsy was significantly higher for the lower thoracic spine (97.6%) than for the middle (90.0%) or upper thoracic spine (80.4%) (P < 0.05 and P < 0.025, respectively). The diagnostic accuracy was significantly higher for lytic lesions (96.4%) than for sclerotic lesions (81.3%) (P < 0.010). The accuracy of biopsies performed using the transpedicular approach (91.0%) was not significantly different from that of biopsies performed using posterolateral approaches (91.5%) (0.25 < P < 0.5).

The definition of major bleeding varies between studies on surgical patients, particularly regarding the criteria for surgical wound-related bleeding. This diversity contributes to the difficulties in comparing data between trials. The Scientific and Standardization Committee (SSC), through its subcommittee on Control of Anticoagulation, of the International Society on Thrombosis and Haemostasis has previously published a recommendation for a harmonized definition of major bleeding in non-surgical studies. That definition has been adopted by the European Medicines Agency and is currently used in several non-surgical trials. A preliminary proposal for a parallel definition for surgical studies was presented at the 54(th) Annual Meeting of the SSC in Vienna, July 2008. Based on those discussions and further consultations with European and North American surgeons with experience from clinical trials a definition has been developed that should be applicable to all agents that interfere with hemostasis. The definition and the text that follows have been reviewed and approved by relevant co-chairs of the subcommittee and by the Executive Committee of the SSC. The intention is to seek approval of this definition from the regulatory authorities to enhance its incorporation into future clinical trial protocols.

Evaluations of Factors Predicting the Need for an Extra-Cervical Approach for Intra-Thoracic Goiter

Full Text Available Introduction: Intra-thoracic goiter refers to the extension of enlarged thyroid tissue into the thoracic inlet. This condition can produce symptoms of compression on adjacent organs and can sometimes be accompanied by malignant transformation. Therefore surgical treatment is almost always necessary. In order to remove the pathology with the fewest post-operative complications, selection of the appropriate surgical approach is essential. In this study we aimed to detect the criteria which help us select the best therapeutic approach.   Materials and Methods: In this retrospective study, 82 patients with intra-thoracic goiter were investigated. Their data were extracted from medical records and analyzed using SPSS software.   Results: Overall 82 patients, 18 (21% males and 64 (78% females with mean age of 56.38 years were studied. The most common clinical symptoms were mass (95% and dyspnea (73%. In most patients, the surgical approach was cervical (90.2%, while 9.8% of patients required an extra-cervical approach. Post-operation complications were observed in 17.1% of patients; the most common being transient recurrent laryngeal nerve paralysis (4.9%. Malignancy was reported in the histopathology of seven patients (8.5%. The most common malignant histopathology was papillary thyroid carcinoma (7.3%. Extension of the thyroid tissue below the uppermost level of the aortic arch was significantly correlated with the need for an extra-cervical approach to surgery (P

Phrenic nerve lesion is a known complication of thoracic surgical intervention, but it is rarely described following thymectomy and lung surgery. To review the literature on thoracic intervention and phrenic nerve lesion and to describe four new cases, in which regular neurophysiological studies were performed. We reviewed the literature concerning phrenic nerve lesion after cardiac, lung and thymus surgical interventions. We described four cases of phrenic nerve lesion, three associated with thymectomy and one in lung surgery. The review shows that cryogenic or thermal injuries during cardiac surgeries are associated with good prognosis. The information on the outcome of phrenic nerve lesion in thymectomy or lung surgery is insufficient. Our cases and this review suggest that phrenic lesion in the last two interventions are associated with a poor recovery. Our data suggests that the prognosis of phrenic nerve lesion following thoracic intervention depends on the nature of the damage. Probably, in thymectomy and lung surgery, nerve stretch or laceration are involved, consequently the outcome is poorer in comparison with cardiac surgery, where cold lesion is more frequent. Neurophysiological tests give a direct, quantified and reliable assessment of nerve regeneration. Copyright © 2011 Elsevier B.V. All rights reserved.

The red panda ( Ailurus fulgens ) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The natural distribution of the red panda is in the Himalayas and southern China. Thoracic diseases such as dirofilariasis, hypertrophic cardiomyopathy, tracheal obstruction, lung worm infestation, and pneumonia have been reported in the red panda. The aim of this study was to describe the normal radiographic thoracic anatomy of captive red pandas as a species-specific reference for routine health examinations and clinical cases. Right lateral (RL) and dorsoventral (DV) inspiratory phase views of the thorax were obtained in 11 adult captive red pandas. Measurements were made and ratios calculated to establish reference ranges for the mean vertebral heart score on the RL (8.34 ± 0.25) and DV (8.78 ± 0.34) views and the mean ratios of the caudal vena cava diameter to the vertebral body length above tracheal bifurcation (0.67 ± 0.05) and tracheal diameter to the width of the third rib (2.75 ± 0.24). The majority of animals (10/11) had 14 thoracic vertebrae, except for one animal that had 15 thoracic vertebrae. Rudimentary clavicles were seen in 3/11 animals. The ovoid, oblique cardiac silhouette was more horizontally positioned and elongated in older animals. A redundant aortic arch was seen in the oldest animal. The trachea was seen with mineralized cartilage rings in all animals. The carina was clearly seen in the majority of animals (10/11). Variations exist in the normal radiographic thoracic anatomy of different species. Knowledge of the normal radiographic thoracic anatomy of the red panda should prove useful for routine health examinations and in the diagnosis of thoracic diseases.

2014-05-01

As the largest scientific organisation world-wide exclusively dedicated to general thoracic surgery (GTS), the European Society of Thoracic Surgeons (ESTS) recognized that one of its priorities is education. The educational platform designed ESTS addresses not only trainees, but also confirmed thoracic surgeons. The two main aims are (I) to prepare trainees to graduation and to the certification by the European Board of Thoracic Surgery and (II) to offer opportunities for continuous medical education in the perspective of life-long learning and continuous professional development to certified thoracic surgeons. It is likely that recertification will become an obligation during the coming decade. At its inception, the platform differentiated two different events. A 6-day course emphasizing on theoretic knowledge was created in Antalya in 2007. The same year, a 2-day school oriented to practical issues with hands-on in the animal lab was launched in Antalya. These two teaching tracks need further development. In the knowledge track, we intend to organize highly specialized 2-day courses to deepen insight into theoretical questions. The skill track will be implemented by specialized courses for high technology such as tracheal surgery, ECMO, robotics or chest wall reconstruction. In order to promote tomorrows' leadership, we created an academic competence track giving an insight into medical communication, methodology and management. We also had to respond to an increasing demand from the Russian speaking countries, where colleagues may face problems to attend western meetings, and where the language bareer may be a major impediment. We initiated a Russian school with three events yearly in 2012. Contemporary teaching must be completed with an e-learning platform, which is currently under development. The school activities are organized by the educational committee, which is headed by the ESTS Director of Education, assisted by coordinators of the teaching tracks and

Sara Socorro Faria

2015-04-01

Full Text Available INTRODUCTION: Optimum treatment for postoperative pain has been of fundamental importance in surgical patient care. Among the analgesic techniques aimed at this group of patients, thoracic paravertebral block combined with general anesthesia stands out for the good results and favorable risk-benefit ratio. Many local anesthetics and other adjuvant drugs are being investigated for use in this technique, in order to improve the quality of analgesia and reduce adverse effects. OBJECTIVE: Evaluate the effectiveness and safety of paravertebral block compared to other analgesic and anesthetic regimens in women undergoing breast cancer surgeries. METHODS: Integrative literature review from 1966 to 2012, using specific terms in computerized databases of articles investigating the clinical characteristics, adverse effects, and beneficial effects of thoracic paravertebral block. RESULTS: On the selected date, 16 randomized studies that met the selection criteria established for this literature review were identified. Thoracic paravertebral block showed a significant reduction of postoperative pain, as well as decreased pain during arm movement after surgery. CONCLUSION: Thoracic paravertebral block reduced postoperative analgesic requirement compared to placebo group, markedly within the first 24 h. The use of this technique could ensure postoperative analgesia of clinical relevance. Further studies with larger populations are necessary, as paravertebral block seems to be promising for preemptive analgesia in breast cancer surgery.

To describe the surgical treatment and outcome for juvenile dogs with cranial thoracic vertebral canal stenosis treated by unilateral hemilaminectomy. Case series. Three large-breed brachycephalic dogs of various breeds (Dogue de Bordeaux, Australian Bulldog, Boerboel) with neurological signs consistent with a myelopathy of the third thoracic (T) to third lumbar (L) spinal cord segment. Information on clinical presentation, diagnostic imaging, surgical procedures, postoperative complications, recovery and outcome is described. Neurological signs were present and progressive for two to four weeks prior to surgery and ranged from mild ataxia to paralysis. Cranial thoracic vertebral canal stenosis was diagnosed with computed tomography imaging. Lateral and dorsolateral spinal cord compression was present at multiple sites between T2 and T6. Alternating left and right-sided compressions were common. Surgical treatment was by unilateral, continuous hemilaminectomy over three to six vertebral spaces. Postoperative morbidity was minimal and return of independent ambulation was rapid (median: 13.5 days, range: 2-29 days). Neurological status in one dog worsened four months after surgery due to reoccurrence of osseous compression; unilateral hemilaminectomy was repeated in this dog. Long-term follow-up ranged from six to 10 months; neurological signs had completely resolved in one dog and substantially improved in the other two dogs. Unilateral hemilaminectomy was associated with rapid return of independent ambulation and substantial improvement in neurological scores.

Thoracic endovascular aortic repair has a lower perceived risk than open surgical repair and has become an increasingly popular alternative. Whether general consensus exists regarding candidacy for either operation among open and endovascular specialists is unknown. A retrospective review of isolated descending thoracic aortic aneurysm at our institution between January 2005 and October 2015 was performed, excluding trauma and dissection. Two cardiac surgeons, 2 cardiovascular surgeons, 1 vascular surgeon, and 1 interventional radiologist gave their preference for open vs endovascular repair. Interobserver agreement was assessed with the kappa coefficient. k-means clustering agnostically grouped various patterns of agreement. The mean rating was predicted using least absolute shrinkage and selection operator regression. Negative binomial regression predicted the discrepancy between our panel of raters and the historical operation. Generalized estimating equation modeling was then used to evaluate the association between the extent of discrepancy and the adverse perioperative outcome. There were 77 patients with preoperative imaging studies. Pairwise interobserver agreement was only fair (median weighted kappa 0.270 [interquartile range 0.211-0.404]). Increasing age and proximal neck length predicted an increasing preference for thoracic endovascular aortic repair in our panel; larger proximal neck diameter predicted a general preference for open surgical repair. Increasing proximal neck diameter predicted a larger discrepancy between our panel and the historical operation. Greater discrepancy was associated with adverse outcome. Substantial disagreement existed among our panel, and an exploratory analysis of the effect of increasing discrepancy demonstrated an association with adverse perioperative outcome. An investigation of the effect of a thoracic aortic team with open and endovascular specialists is warranted. Copyright © 2017 Elsevier Inc. All rights

2013-01-01

Full Text Available We report three cases of a rare pattern of mid-thoracic spine injuries after horse racing falls and discuss possible causative factors and prevention measurements to reduce injury rates in professional riding and racing. Three patients, 2 male and 1 female with a mean age of 28 years old, underwent surgical treatment for mid-thoracic fractures after professional equestrian activities. The ASIA scale was E in one patient, B in the other one and A in the third. Multilevel posterior fusion was used in two patients and somatectomy plus fusion in the other. Follow up evaluation included changing of the ASIA scale, functional outcome and participation in equestrian activities. One patient fully recovered after surgery. Two patients remained paraplegic despite early surgical treatment and prolonged rehabilitation therapy. All patients had ended their professional equestrian career. This report analyzes possible mechanisms of injury and the pattern of mid-thoracic spine fractures after professional horse riding injuries. Despite skill improvements and continued safety education for horse riding, prophylactic measures for both the head and the spine should be refined. According to our study, additional mid-thoracic spinal protection should be added.

Postoperative ileus is a major complication of abdominal surgical procedures To evaluate the incidence of ileus and gastrointestinal morbidity in patients who received immediate postoperative feeding and bowel stimulation after undergoing major gynecologic surgical procedures. During a 5-year period, the authors tracked demographic, surgical outcome, and follow-up information for 707 patients who underwent major gynecologic operations. All patients received the same postoperative orders, including immediate feeding of a diet of choice and bowel stimulation with 30 mL of magnesium hydroxide (milk of magnesia) twice daily until bowel movements occurred. Of 707 patients, 6 (<1%) had postoperative ileus. No patients experienced postoperative bowel obstruction and 2 patients (0.3%) had postoperative intestinal leak. No serious adverse effects associated with bowel stimulation were reported. Immediate postoperative feeding and bowel stimulation is a safe and effective approach to preventing ileus in patients who undergo major gynecologic surgical procedures.

Biomedicine represents a new scientific field at the interface of human, molecular and cell biology and medicine. Comprising the diverse disciplines of stem cell research, tissue engineering and material sciences, biomedicine gives rise to new approaches in research and therapy for - to date - unmet medical issues. Biomedical research is currently conducted in many medical, especially surgical subspecialties, and a number of successful developments have already been brought to clinical application. Concerning thoracic surgery, biomedical approaches are pursued primarily for tissue and organ replacement of the upper airways, lung and thoracic wall. In spite of a comparatively small research foundation, five different concepts have been clinically implemented worldwide, due to a lack of established treatment options in the case of extensive disease of the greater airways. In this review, the clinical background and the tissue-specific basics of tracheobronchial biomedicine are presented. Georg Thieme Verlag KG Stuttgart · New York.

2014-01-01

Full Text Available Recurrent deep venous thrombosis, involving bilateral upper extremities, is an extremely rare phenomenon. We are presenting a 43-year-old man who was diagnosed with left upper extremity deep vein thrombosis (UEDVT and was treated with anticoagulation and surgical decompression in 2004. 9 years later, he presented with right arm swelling and was diagnosed with right UEDVT using US venous Doppler. Venogram showed compression of the subclavian vein by the first rib, diagnosing thoracic outlet syndrome (TOS. He was treated with anticoagulation and local venolysis and later by surgical decompression of the subclavian vein. Bilateral UEDVT, as mentioned above, is an extremely rare condition that is uncommonly caused by TOS. To our knowledge, we are reporting the first case of bilateral UEDVT due to TOS. Diagnosis usually starts with US venous Doppler to detect the thrombosis, followed by the gold standard venogram to locate the area of obstruction and lyse the thrombus if needed. The ultimate treatment for TOS remains surgical decompression of the vascular bundle at the thoracic outlet.

In recent years, the search for a less invasive and thus, less painful approach has driven technical innovation in modern thoracic surgery. In this context, subxiphoid uniportal approach has emerged as an alternative to avoid intercostal space manipulation and decrease postoperative pain and intercostal nerve chronic impairment. Subxiphoid uniportal major lung resections have been safe and effective procedures when performed by experienced surgeons even in complex cases or unexpected intraoperative situations. We present six of these surgical scenarios such as big tumors, incomplete or absent fissures, hilar calcified lymph nodes, active bleeding and massive adhesions to show the feasibility of subxiphoid approach to manage even these conditions.

Video-assisted thoracic surgery (VATS) emerged as a minimally invasive surgery for diseases in the field of thoracic surgery. We herein reviewed our experience on thoracoscopic lobectomy for early lung cancer and evaluated Health System use. A cost-effectiveness study was performed comparing VATS vs. open thoracic surgery (OPEN) for lung cancer patients. Demographic data, tumor localization, dynamic pulmonary function tests [forced vital capacity (FVC), forced expiratory volume in one second (FEV1), diffusion capacity (DLCO) and maximal oxygen uptake (VO2max)], surgical approach, postoperative details, and complications were recorded and analyzed. One hundred seventeen patients underwent lung resection by VATS (n=42, 36%; age: 63±9 years old, 57% males) or OPEN (n=75, 64%; age: 61±11 years old, 73% males). Pulmonary function tests decreased just after surgery with a parallel increasing tendency during first 12 months. VATS group tended to recover FEV1 and FVC quicker with significantly less clinical and post-surgical complications (31% vs. 53%, P=0.015). Costs including surgery and associated hospital stay, complications and costs in the 12 months after surgery were significantly lower for VATS (P<0.05). The VATS approach surgery allowed earlier recovery at a lower cost than OPEN with a better cost-effectiveness profile.

Objective: To analyse the outcome in terms of morbidity and mortality in blunt thoracic trauma patients in tertiary care hospitals, Rawalpindi. Methods: The prospective study was conducted from March 2008 to February 2012 in surgical wards of public and private sector hospitals in Rawalpindi. A total of 221 patients were included from the Combined Military Hospital during 2008-10, and 43 patients from the Heart's International during 2011-12. The patients reported to emergency department within 48 hours of trauma. All patients were subjected to detailed history and respiratory system examination to ascertain fracture of ribs, flail segment and haemopneumothorax. The diagnosis of chest wall injuries, parenchymal pulmonary injuries and pleural involvement were made on the basis of chest radiographs and computed tomography scan of the chest. The lung contusion was assessed by the number of lobes involved. SPSS 19 was used for statistical analysis. Results: Of the 264 patients in the study, 211 (80%) were males and 54 (20%) females. The overall mean age was 44.8+-17.1 years. Over all morbidity was 222 (84.2%); morbidity (minor) was 128 (48.5%), and morbidity (major) was 94 (35.7%). Mortality was 26 (9.8%) and 16 (6%) cases had normal outcome. Conclusion: Early identification and aggressive management of blunt thoracic trauma is essential to reducing significant rates of morbidity and mortality. (author)

2014-09-01

To explore an method and the effectiveness of surgical treatment of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity (Cobb angle ≥ 55°) and paraplegia. Between January 2009 and January 2013, 13 cases of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity and paraplegia were treated by one-stage posterior vertebral column resection (PVCR), debridement, bone grafting, and instrumentation fixation. Of 13 patients, 7 were male and 6 were female with an average age of 23.5 years (range, 14-49 years). The disease duration was 13-38 months (mean, 19 months). The Cobb angle of kyphosis was (65.23 ± 7.95)°. The visual analogue scale score (VAS) was 7.38 ± 0.31. In 13 patients with incomplete paraplegia, 1 case was classified as Frankel grade B, 7 cases as grade C, and 5 cases as grade D. The lesion involved 2 vertebrae bodies in 7 cases (T8, 9 in 1 case, T11, 12 in 2 cases, and T12, L1 in 4 cases), 3 vertebrae bodies in 4 cases (T10-12 in 2 cases, T9-11 in 1 case, and T11-L1 in 1 case), and 4 vertebrae bodies in 2 cases (T4-7 in 1 case and T6-9 in 1 case). Imaging examination showed paravertebral abscess in 10 cases. Healing of incision by first intention was obtained in all patients. The neurological injury and pulmonary infection occurred in 3 cases and 2 cases respectively, which were cured after symptomatic treatment. Thirteen patients were followed up 12-48 months (mean, 17 months). The erythrocyte sedimentation rate restored to normal level in all cases at 3-7 months after operation. All the patients achieved bony fusion at 10-20 months (mean, 14 months) after operation. No fixation loosening, displacement, or fracture occurred during follow-up. Common toxic symptom of tuberculosis disappeared, and there was no recurrence of local tuberculosis. The Cobb angle of kyphosis was corrected to (22.38 ± 1.76)° at 1 week and (22.15 ± 1.83)° at last follow-up, showing significant difference when compared with

A case of thoracic myelopathy with alkaptonuria (ochronotic spondyloarthropathy) is presented. To present and review the first reported case of an alkaptonuric patient with concomitant thoracic myelopathy. Alkaptonuria, a rare hereditary metabolic disease, is characterized by accumulation of homogentistic acid, ochronosis, and destruction of connective tissue resulting in degenerative spondylosis and arthritis. Despite the high incidence of intervertebral disc diseases among patients with alkaptonuria, neurologic symptoms caused by spinal disease are rare. Thoracic myelopathy in a patient with alkaptonuria has not been previously reported. The clinical course, radiologic features, pathology, and treatment outcome of an alkaptonuria patient with thoracic myelopathy was documented. Myelopathy of the patient was caused by rupture of a thoracic intervertebral disc. The neurologic symptoms of the patient were markedly improved after surgery. We have reported for the first time, that an alkaptonuria patient showed thoracic myelopathy caused by rupture of a thoracic intervertebral disc. Decompression followed by the instrumented fusion of the thoracic spine was effective for improving the neurologic symptoms.

Objective In 2012, Medicare began cutting reimbursement for hospitals with high readmission rates. We sought to define the incidence and risk factors associated with readmission after surgery. Methods A total of 230,864 patients discharged after general, upper gastrointestinal (GI), small and large intestine, hepatopancreatobiliary (HPB), vascular, and thoracic surgery were identified using the 2011 American College of Surgeons National Surgical Quality Improvement Program. Readmission rates and patient characteristics were analyzed. A predictive model for readmission was developed among patients with length of stay (LOS) 10 days or fewer and then validated using separate samples. Results Median patient age was 56 years; 43% were male, and median American Society of Anesthesiologists (ASA) class was 2 (general surgery: 2; upper GI: 3; small and large intestine: 2; HPB: 3; vascular: 3; thoracic: 3; P readmission was 7.8% (general surgery: 5.0%; upper GI: 6.9%; small and large intestine: 12.6%; HPB: 15.8%; vascular: 11.9%; thoracic: 11.1%; P readmission included ASA class, albumin less than 3.5, diabetes, inpatient complications, nonelective surgery, discharge to a facility, and the LOS (all P readmission. A simple integer-based score using ASA class and the LOS predicted risk of readmission (area under the receiver operator curve 0.702). Conclusions Readmission among patients with the LOS 10 days or fewer occurs at an incidence of at least 5% to 16% across surgical subspecialties. A scoring system on the basis of ASA class and the LOS may help stratify readmission risk to target interventions. PMID:24022435

To assess the safety, feasibility and efficacy of catheter-directed thrombolysis for thoracic central venous thrombosis in both cancer and non-cancer patients. A retrospective case series of 68 patients, including 35 with active cancer and 33 without cancer, was analysed. They all received catheter-directed thrombolysis with alteplase or urokinase for symptomatic acute major thoracic vein thrombosis. Substantial clot lysis was obtained in 62 out of 68 patients (91%), the results being 88.6 and 93.8% for cancer and non-cancer patients respectively (P = 0.68). The mean infusion time in patients with and without cancer was 2.11 and 1.84 days respectively (P = 0.3259). Procedure-related complications occurred in two cancer patients (8.6%) and in seven non-cancer patients (21%) (P = 0.18). One cancer patient developed a fatal intracranial bleeding. Additional intervention after successful lysis was performed in cancer (n = 18; 51%) as well as in non-cancer patients (n = 29; 88%). Catheter-directed thrombolysis is a feasible and highly effective interventional procedure with an acceptable safety profile in selected patients with and without cancer for the treatment of symptomatic thoracic central venous thrombosis. In most cases, additional endovascular or surgical procedures are required to restore and maintain vessel patency after successful thrombolysis. (orig.)

Thoracic spine pain

Full Text Available Thoracic spine pain, or thoracalgia, is one of the common reasons for seeking for medical advice. The epidemiology and semiotics of pain in the thoracic spine unlike in those in the cervical and lumbar spine have not been inadequately studied. The causes of thoracic spine pain are varied: diseases of the cardiovascular, gastrointestinal, pulmonary, and renal systems, injuries to the musculoskeletal structures of the cervical and thoracic portions, which require a thorough differential diagnosis. Facet, costotransverse, and costovertebral joint injuries and myofascial syndrome are the most common causes of musculoskeletal (nonspecific pain in the thoracic spine. True radicular pain is rarely encountered. Traditionally, treatment for thoracalgia includes a combination of non-drug and drug therapies. The cyclooxygenase 2 inhibitor meloxicam (movalis may be the drug of choice in the treatment of musculoskeletal pain.

Minimally invasive procedures are used for the surgical treatment of lung cancer. Two techniques are proposed: video-assisted thoracic surgery or robotic-assisted thoracic surgery. Our goal was to study the economic impact of our long-standing program for minimally invasive procedures for major lung resection. We conducted a single-centre, 1-year prospective cost study. Patients who underwent lobectomy or segmentectomy were included. Patient characteristics and perioperative outcomes were collected. Medical supply expenses based on the microcosting method and capital depreciation were estimated. Total cost was evaluated using a national French database. One hundred twelve patients were included, 57 with and 55 without robotic assistance. More segmentectomies were performed with robotic assistance. The median length of stay was 5 days for robotic-assisted and 6 days for video-assisted procedures (P = 0.13). The duration of median chest drains (4 days, P = 0.36) and of operating room time (255 min, P = 0.55) was not significantly different between the groups. The overall conversion rate to thoracotomy was 9%, significantly higher in the video-assisted group than in the robotic group (16% vs 2%, P = 0.008). No difference was observed in postoperative complications. The cost of most robotic-assisted procedures ranged from €10 000 to €12 000 (median €10 972) and that of most video-assisted procedures ranged from €8 000 to €10 000 (median €9 637) (P = 0.007); median medical supply expenses were €3 236 and €2 818, respectively (P = 0.004). The overall mean cost of minimally invasive techniques (€11 759) was significantly lower than the mean French cost of lung resection surgical procedures (€13 424) (P = 0.001). The cost at our centre of performing minimally invasive surgical procedures appeared lower than the cost nationwide. Robotic-assisted thoracic surgery demonstrated acceptable additional costs

Endovascular stent-graft management of thoracic aortic diseases

2001-01-01

The traditional standard therapy for descending thoracic aortic aneurysm (TAA) is open operative repair with graft replacement of the diseased aortic segment. Despite important advances in surgical techniques, anesthetic management, and post-operative care over the last 30 years, the mortality and morbidity of surgery remains considerable, especially in patients at high risk for thoracotomy because of coexisting severe cardiopulmonary abnormalities or other medical diseases. The advent of endovascular stent-graft technology provides an alternative to open surgery for selected patients with TAA. The initial experience suggests that stent-graft therapy potentially may reduce the operative risk, hospital stay and procedural expenses of TAA repair. These potential benefits are especially attractive for patients at high risk for open TAA repair. Current results of endovascular TAA therapy document operative mortalities of between 0 and 4%, aneurysm thrombosis in 90 and 100% of cases, and paraplegia as a complication in 0 and 1.6% of patients. The early success of stent-graft repair of TAA has fostered the application of these devices for the management of a wide variety of thoracic aortic pathologies, including acute and chronic dissection, intramural hematoma, penetrating ulcer, traumatic injuries, and other diseases. The results of prospective controlled trials that compare the outcomes of stent-graft therapy with those of surgical treatment in patients with specific types of aortic disease are anxiously awaited before recommendations regarding the general use of these new devices can be made with confidence

Asphyxiating Thoracic Dysplasia is the most frequent form of Small Thorax - Short Rib Syndromes. Asphyxiating Thoracic Dysplasia in two patients with different clinical course is reported. Radiographic examination is the only method to diagnose Asphyxiating Thoracic Dysplasia with certainty. The correct diagnosis is important for prognostication and genetic counseling. It also excludes the necessity of further, often expensive investigations. (author)

Surgical decompression of thoracic spinal stenosis in achondroplasia: indication and outcome.

Science.gov (United States)

Vleggeert-Lankamp, Carmen; Peul, Wilco

2012-08-01

The achondroplastic spinal canal is narrow due to short pedicles and a small interpedicular distance. Compression of neural structures passing through this canal is therefore regularly encountered but rarely described. Symptomatology, radiological evaluation, and treatment of 20 patients with achondroplasia who underwent decompression of the thoracic spinal cord are described and outcome is correlated with the size of the spinal canal and the thoracolumbar kyphotic angle. Scores from the modified Japanese Orthopaedic Association scale, Nurick scale, European Myelopathy scale, Cooper myelopathy scale for lower extremities, and Odom criteria before and after surgery were compared. Magnetic resonance imaging was evaluated to determine the size of the spinal canal, spinal cord compression, and presence of myelomalacia. The thoracolumbar kyphotic angle was measured using fluoroscopy. Patient symptomatology included deterioration of walking pattern, pain, cramps, spasms, and incontinence. Magnetic resonance images of all patients demonstrated spinal cord compression due to degenerative changes. Surgery resulted in a slight improvement on all the ranking scales. Surgery at the wrong level occurred in 15% of cases, but no serious complications occurred. The mean thoracolumbar kyphotic angle was 20°, and no correlation was established between this angle and outcome after surgery. No postoperative increase in this angle was reported. There was also no correlation between size of the spinal canal and outcome. Decompressive surgery of the thoracic spinal cord in patients with achondroplasia can be performed safely if anatomical details are taken into consideration. Spondylodesis did not appear essential. Special attention should be given to the method of surgery, identification of the level of interest, and follow-up of the thoracolumbar kyphotic angle.

To identify the incidence of clinically significant findings on preoperative thoracic radiographs in dogs with gastric dilatation-volvulus (GDV) and to determine if those findings are associated with survival. Retrospective study from 2000 to 2010. Urban university small animal teaching hospital. One hundred and one dogs diagnosed with GDV that had thoracic radiographs obtained preoperatively, and medical records available with the following information available: signalment, time of presentation, respiratory status, plasma lactate, presence of cardiac arrhythmias, reason for thoracic radiographs, radiographic findings, and outcome. None. Findings on preoperative thoracic radiographs included small vena cava (40%), esophageal dilation (39%), microcardia (34%), aspiration pneumonia (14%), cardiomegaly (5%), pulmonary nodule (4%), pulmonary edema (2%), sternal lymphadenopathy (1%), and pulmonary bullae (1%). Eighty-four percent of dogs (85 out of 101) survived to discharge. Dogs without cardiomegaly on presenting thoracic radiographs had a 10.2 greater odds of surviving to discharge. The most common findings on preoperative thoracic radiographs include esophageal dilation, microcardia, and a small vena cava while the incidence of pulmonary nodules was low. A negative association between survival and presence of cardiomegaly on preoperative thoracic radiographs in dogs with GDV supports the need to obtain these images for prognostic information in spite of the emergency surgical nature of the GDV. The main limitations of this study include the possibilities of type I and type II errors, the retrospective nature of the study, and the lack of well-defined criteria for obtaining thoracic radiographs. © Veterinary Emergency and Critical Care Society 2012.

Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

Patients are increasingly using the Internet as a source of information on medical conditions. Because the average American adult reads at a 7th- to 8th-grade level, the National Institutes of Health recommend that patient education material be written between a 4th- and 6th-grade level. In this study, we assess and compare the readability of patient education materials on major surgical subspecialty Web sites relative to otolaryngology. Descriptive and correlational design. Patient education materials from 14 major surgical subspecialty Web sites (American Society of Colon and Rectal Surgeons, American Association of Endocrine Surgeons, American Society of General Surgeons, American Society for Metabolic and Bariatric Surgery, American Association of Neurological Surgeons, American Congress of Obstetricians and Gynecologists, American Academy of Ophthalmology, American Academy of Orthopedic Surgeons, American Academy of Otolaryngology-Head and Neck Surgery, American Pediatric Surgical Association, American Society of Plastic Surgeons, Society for Thoracic Surgeons, and American Urological Association) were downloaded and assessed for their level of readability using 10 widely accepted readability scales. The readability level of patient education material from all surgical subspecialties was uniformly too high. Average readability levels across all subspecialties ranged from the 10th- to 15th-grade level. Otolaryngology and other surgical subspecialties Web sites have patient education material written at an education level that the average American may not be able to understand. To reach a broader population of patients, it might be necessary to rewrite patient education material at a more appropriate level.

2010-01-01

We inspected the feasibility of minimally invasive surgery for superficial esophageal cancer, the trans-hiatal approach without thoracotomy. We examined the surgical outcomes of 33 superficial esophageal cancer whose cancer had invaded the submucosal layer and who underwent resection in our hospital between April 2003 and April 2009. The patients who had tumor invasion of within the sm1 and no metastasis to the upper and middle mediastinum lymph nodes were operated on by the trans-hiatal esophagectomy (THE). The other patients were underwent ordinary trans-thoracic esophagectomy (TTE). After the operations, we recommended adjuvant chemoradiation therapy for all patients whose tumor were histopathologically proved to involve the sm2 layer as well as the vessels and/or lymphatic duct. Of our 33 cases, nine were diagnosed as pM1 or pM2. Two were diagnosed as pM3, one of which had lymph node metastasis. Eleven cases were diagnosed as pSM1, four as pSM2, and seven as pSM3; and lymph node metastasis was observed in 4 pSM1 cases (36%), 2 pSM2 cases (50%) and 5 pSM3 cases (71.4%). The five-year survival rate in all cases was 89.6%. The five-year survival rate by operating method was 100% in THE cases or 80.9% in TTE cases. The rates by tumor depth of invasion was 100% in pM1-2 cases, 92.3% in pM3-SM1 cases and 78.8% in pSM2-3 cases. It is concluded that the surgical outcome of THE in accordance with our indication criteria is equal to that of TTE for superficial esophageal cancer. (author)

As the adoption of robotic procedures becomes more widespread, additional risk related to the learning curve can be expected. This article reports the results of a Delphi process to define procedures to optimize robotic training of thoracic surgeons and to promote safe performance of established robotic interventions as, for example, lung cancer and thymoma surgery. In June 2016, a working panel was spontaneously created by members of the European Society of Thoracic Surgeons (ESTS) and European Association for Cardio-Thoracic Surgery (EACTS) with a specialist interest in robotic thoracic surgery and/or surgical training. An e-consensus-finding exercise using the Delphi methodology was applied requiring 80% agreement to reach consensus on each question. Repeated iterations of anonymous voting continued over 3 rounds. Agreement was reached on many points: a standardized robotic training curriculum for robotic thoracic surgery should be divided into clearly defined sections as a staged learning pathway; the basic robotic curriculum should include a baseline evaluation, an e-learning module, a simulation-based training (including virtual reality simulation, Dry lab and Wet lab) and a robotic theatre (bedside) observation. Advanced robotic training should include e-learning on index procedures (right upper lobe) with video demonstration, access to video library of robotic procedures, simulation training, modular console training to index procedure, transition to full-procedure training with a proctor and final evaluation of the submitted video to certified independent examiners. Agreement was reached on a large number of questions to optimize and standardize training and education of thoracic surgeons in robotic activity. The production of the content of the learning material is ongoing.

Purpose: The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME) region. Methods: A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV), anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, Panesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05). Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database (GTSD) reports outstanding results for lung and esophageal cancer resection. However, a major weakness of the GTSD has been the lack of validation of this voluntary registry. The purpose of this study was to perform an external, independent audit to assess the accuracy of the data collection process and the quality of the database. An independent firm was contracted to audit 5% of sites randomly selected from the GTDB in 2011. Audits were performed remotely to maximize the number of audits performed and reduce cost. Auditors compared lobectomy cases submitted to the GTSD with the hospital operative logs to evaluate completeness of the data. In addition, 20 lobectomy records from each site were audited in detail. Agreement rates were calculated for 32 individual data elements, 7 data categories pertaining to patient status or care delivery, and an overall agreement rate for each site. Six process variables were also evaluated to assess best practice for data collection and submission. Ten sites were audited from the 222 participants. Comparison of the 559 submitted lobectomy cases with operative logs from each site identified 28 omissions, a 94.6% agreement rate (discrepancies/site range, 2 to 27). Importantly, cases not submitted had no mortality or major morbidity, indicating a lack of purposeful omission. The aggregate agreement rates for all categories were greater than 90%. The overall data accuracy was 94.9%. External audits of the GTSD validate the accuracy and completeness of the data. Careful examination of unreported cases demonstrated no purposeful omission or gaming. Although these preliminary results are quite good, it is imperative that the audit process is refined and continues to expand along with the GTSD to insure reliability of the database. The audit results are currently being incorporated into educational and quality improvement processes to add further value. Copyright �

Use of topical tranexamic acid or aminocaproic acid to prevent bleeding after major surgical procedures.

2012-01-01

To evaluate the literature describing topical use of tranexamic acid or aminocaproic acid for prevention of postoperative bleeding after major surgical procedures. Literature was retrieved through MEDLINE (1946-September 2011) and International Pharmaceutical Abstracts (1970-September 2011) using the terms tranexamic acid, aminocaproic acid, antifibrinolytic, topical, and surgical. In addition, reference citations from publications identified were reviewed. All identified articles in English were evaluated. Clinical trials, case reports, and meta-analyses describing topical use of tranexamic acid or aminocaproic acid to prevent postoperative bleeding were included. A total of 16 publications in the setting of major surgical procedures were included; the majority of data were for tranexamic acid. For cardiac surgery, 4 trials used solutions containing tranexamic acid (1-2.5 g in 100-250 mL of 0.9% NaCl), and 1 trial assessed a solution containing aminocaproic acid (24 g in 250 mL of 0.9% NaCl). These solutions were poured into the chest cavity before sternotomy closure. For orthopedic procedures, all of the data were for topical irrigation solutions containing tranexamic acid (500 mg-3 g in 50-100 mL of 0.9% NaCl) or for intraarticular injections of tranexamic acid (250 mg to 2 g in 20-50 mL of 0.9% sodium chloride, with or without carbazochrome sodium sulfate). Overall, use of topical tranexamic acid or aminocaproic acid reduced postoperative blood loss; however, few studies reported a significant reduction in the number of packed red blood cell transfusions or units given, intensive care unit stay, or length of hospitalization. Topical application of tranexamic acid and aminocaproic acid to decrease postsurgical bleeding after major surgical procedures is a promising strategy. Further data are needed regarding the safety of this hemostatic approach.

Multimodal therapeutic concepts in cases of neoplasms of the intestinal tract entail the risk of undesirable complications with respect to healing of wounds and anastomoses. The separate steps of a combined treatment consisting radiation therapy and partial resection of the thoracic esophagus were performed in animal experiments to study the effect of radiation therapy on the healing of anastomoses. Adult non-purebred dogs were irradiated in a defined thoracic field with a Betatron (42 MeV) and subsequently underwent esophagectomy. After resection of a 2 cm segment of the esophagus end-to-end anastomosis was performed. Different methods of irradiation and postoperative observation times resulted in a total of 8 groups of 3 animals each. Fractionated irradiation was definitely better tolerated than irradiation with a high single doses. The temporary delay of the anastomotic healing was documented histologically. Only one case of anastomotic leakage occurred, and impaired wound healing was observed in only one animal. The mode of irradiation must be regarded as important for the clinical course. Fractionated preoperative irradiation in the area of the thoracic esophagus does not lead to any relevant disturbance of wound and anastomotic healing with meticulous surgical technique and adequate intensive postoperative care. The basic feasibility of surgical therapy combined with preoperative radiotherapy in tumors of the upper digestive tract was confirmed by our experimental work.

Prospective cohort study. Prospectively compare patient-reported as well as clinical and radiologic outcomes after anterior or posterior surgery for right thoracic adolescent idiopathic scoliosis (AIS) in a single center by the same surgeons. Anterior and posterior spinal instrumentation and arthrodesis are both well-established treatments of thoracic AIS. The majority of studies comparing the 2 approaches have focused on radiographic outcomes. There remains a paucity of prospectively gathered patient-reported outcomes comparing surgical approaches. Forty-two consecutive patients with right thoracic AIS were treated in a single center by one of 2 surgeons with either anterior (n=18) or posterior (n=24) approaches and followed up for over 2 years. Radiographic, clinical, and patient-reported outcomes of the Modified Scoliosis Research Society Outcome Instrument were gathered and analyzed by an independent surgeon. Patients reported significant improvements in all areas of the Modified Scoliosis Research Society Outcome Instrument, especially pain and self-image domains. There were no significant differences in the degree of improvement in any domains between the groups. Posterior and anterior surgery corrected rib hump by 53% and 61%, respectively (P=0.4). The Main thoracic curve Cobb angle was corrected from 69 to 26 degrees (62%) by posterior surgery and 61 to 23 degrees (64%) by anterior surgery (P=0.6). Posterior surgery significantly reduced kyphosis and lumbosacral lordosis. Anterior surgery had no overall affect of sagittal alignment but seemed able to correct those hypokyphotic preoperatively. Complications differed and were largely approach-related--intrathoracic in anterior and wound-related in posterior surgery. Patients with right thoracic AIS of differing curve types but otherwise similar preoperatively demonstrated that anterior and posterior surgery are largely equivalent. Patient-reported outcomes are improved similarly by either approach. Both offer

Health care resources are costly and should be used judiciously and efficiently. Predicting the duration of surgical procedures is key to optimizing operating room resources. Our objective was to identify factors influencing operative time, particularly surgical team turnover. We performed a single-institution, retrospective review of lobectomy operations. Univariate and multivariate analyses were performed to evaluate the impact of different factors on surgical time (skin-to-skin) and total procedure time. Staff turnover within the nursing component of the surgical team was defined as the number of instances any nurse had to leave the operating room over the total number of nurses involved in the operation. A total of 235 lobectomies were performed by 5 surgeons, most commonly for lung cancer (95%). On multivariate analysis, percent forced expiratory volume in 1 second, surgical approach, and lesion size had a significant effect on surgical time. Nursing turnover was associated with a significant increase in surgical time (53.7 minutes; 95% confidence interval, 6.4-101; P = .026) and total procedure time (83.2 minutes; 95% confidence interval, 30.1-136.2; P = .002). Active management of surgical team turnover may be an opportunity to improve operating room efficiency when the surgical team is engaged in a major pulmonary resection.

An ossified arachnoid membrane combined with cystic formation is rarely reported as a cause of spinal cord compression. We report the case of a 60-year-old man who presented with diffuse ossification of the arachnoid membrane (arachnoid ossification) and multiple cystic changes (arachnoid cyst) at the thoracic and lumbar spine. The lesions were surgically removed and progressive deterioration was prevented, although no marked improvement of neurological symptoms was attained. (orig.)

AIM: To investigate the features of crush thoracic trauma in Sichuan earthquake victims using chest digital radiography (CDR). METHODS: We retrospectively reviewed 772 CDR of 417 females and 355 males who had suffered crush thoracic trauma in the Sichuan earthquake. Patient age ranged from 0.5 to 103 years. CDR was performed between May 12, 2008 and June 7, 2008. We looked for injury to the thoracic cage, pulmonary parenchyma and the pleura. RESULTS: Antero-posterior (AP) and lateral CDR were obtained in 349 patients, the remaining 423 patients underwent only AP CDR. Thoracic cage fractures, pulmonary contusion and pleural injuries were noted in 331 (42.9%; 95% CI: 39.4%-46.4%), 67 and 135 patients, respectively. Of the 256 patients with rib fractures, the mean number of fractured ribs per patient was 3. Rib fractures were mostly distributed from the 3rd through to the 8th ribs and the vast majority involved posterior and lateral locations along the rib. Rib fractures had a significant positive association with non-rib thoracic fractures, pulmonary contusion and pleural injuries (P < 0.001). The number of rib fractures and pulmonary contusions were significant factors associated with patient death. CONCLUSION: Earthquake-related crush thoracic trauma has the potential for multiple fractures. The high number of fractured ribs and pulmonary contusions were significant factors which needed appropriate medical treatment. PMID:22132298

Surgical and nonsurgical treatment of total rupture of the pectoralis major muscle in athletes: update and critical appraisal

Full Text Available Jörn Kircher, Christoph Ziskoven, Thilo Patzer, Daniela Zaps, Bernd Bittersohl, Rüdiger KrauspeUniversity Hospital, Orthopaedic Department, Heinrich-Heine University Düsseldorf, Düsseldorf, GermanyAbstract: The complete rupture of the pectoralis major tendon is an uncommon injury but has become increasingly common among athletes in recent years. This may be due to a higher number of individuals taking part in high-impact sports and weightlifting as well as the use of anabolic substances, which can make muscles and tendons vulnerable to injury. In recent literature, there are only few recommendations to rely on conservative treatment alone, but there are a number of reports and case series recommending early surgical intervention. Comparing the results of the two treatment regimens, there is clear evidence for a superior outcome after surgical repair with better cosmesis, better functional results, regaining of muscle power, and return to sports compared with the conservative treatment. In summary, anatomic surgical repair is the treatment of choice for complete acute ruptures of the pectoralis major tendon or muscle in athletes.Keywords: pectoralis major, rupture, athlete, conservative treatment, surgical treatment, steroid, tendon, sports injury

The da Vinci(®) Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is a computer-assisted (robotic) surgical system designed to enable and enhance minimally invasive surgery. The Food and Drug Administration (FDA) has cleared computer-assisted surgical systems for use by trained physicians in an operating room environment for laparoscopic surgical procedures in general, cardiac, colorectal, gynecologic, head and neck, thoracic and urologic surgical procedures. There are substantial numbers of peer-reviewed papers regarding the da Vinci(®) Surgical System, and a thoughtful assessment of evidence framed by clinical opinion is warranted. The SAGES da Vinci(®) TAVAC sub-committee performed a literature review of the da Vinci(®) Surgical System regarding gastrointestinal surgery. Conclusions by the sub-committee were vetted by the SAGES TAVAC Committee and SAGES Executive Board. Following revisions, the document was evaluated by the TAVAC Committee and Executive Board again for final approval. Several conclusions were drawn based on expert opinion organized by safety, efficacy, and cost for robotic foregut, bariatric, hepatobiliary/pancreatic, colorectal surgery, and single-incision cholecystectomy. Gastrointestinal surgery with the da Vinci(®) Surgical System is safe and comparable, but not superior to standard laparoscopic approaches. Although clinically acceptable, its use may be costly for select gastrointestinal procedures. Current data are limited to the da Vinci(®) Surgical System; further analyses are needed.

Full Text Available The purpose of the reviewThe analysis of the components of enhanced recovery after surgery (ERAS protocols in urologic surgery.Recent findingsERAS protocols has been studied for over 20 years in different surgical procedures, mostly in colorectal surgery. The concept of improving patient care and reducing postoperative complications was also applied to major urologic surgery and especially procedure of radical cystectomy. This procedure is technically challenging, due to a major surgical resection and high postoperative complication rate that may reach 65%. Several clinical pathways were introduced to improve perioperative course and reduce the length of hospital stay. These protocols differ from ERAS modalities in other surgeries. The reasons for this are longer operative time, increased risk of perioperative transfusion and infection, and urinary diversion achieved using transposed intestinal segments. Previous studies in this area analyzed the need for mechanical bowel preparation, postoperative nasogastric tube decompression, as well as the duration of urinary drainage. Furthermore, the attention has also been drawn to perioperative fluid optimization, pain management, and bowel function.SummaryNotwithstanding partial resemblance between the pathways in major urologic surgery and other pelvic surgeries, there are still scarce guidelines for ERAS protocols in urology, which is why further studies should assess the importance of preoperative medical optimization, implementation of thoracic epidural anesthesia and analgesia, and perioperative nutritional management.

To compare the diagnostic accuracy of post-mortem magnetic resonance imaging (PMMR) specifically for non-cardiac thoracic pathology in fetuses and children, compared with conventional autopsy. Institutional ethics approval and parental consent was obtained. A total of 400 unselected fetuses and children underwent PMMR before conventional autopsy, reported blinded to the other dataset. Of 400 non-cardiac thoracic abnormalities, 113 (28 %) were found at autopsy. Overall sensitivity and specificity (95 % confidence interval) of PMMR for any thoracic pathology was poor at 39.6 % (31.0, 48.9) and 85.5 % (80.7, 89.2) respectively, with positive predictive value (PPV) 53.7 % (42.9, 64.0) and negative predictive value (NPV) 77.0 % (71.8, 81.4). Overall agreement was 71.8 % (67.1, 76.2). PMMR was most sensitive at detecting anatomical abnormalities, including pleural effusions and lung or thoracic hypoplasia, but particularly poor at detecting infection. PMMR currently has relatively poor diagnostic detection rates for the commonest intra-thoracic pathologies identified at autopsy in fetuses and children, including respiratory tract infection and diffuse alveolar haemorrhage. The reasonable NPV suggests that normal thoracic appearances at PMMR exclude the majority of important thoracic lesions at autopsy, and so could be useful in the context of minimally invasive autopsy for detecting non-cardiac thoracic abnormalities.

McClintick, Colleen M

2008-01-01

Cases of open pneumothorax have been documented as early as 326 BC. Until the last 50 years, understanding of the epidemiology and treatment of penetrating chest trauma has arisen from military surgery. A better understanding of cardiopulmonary dynamics, advances in ventilatory support, and improvement in surgical technique have drastically improved treatment and increased the survival rate of patients with penetrating thoracic trauma. Open pneumothorax is rare in blunt chest trauma, but can occur when injury results in a substantial loss of the chest wall. This case study presents an adolescent who sustained a large open pneumothorax as a result of being run over by a car. Early and appropriate surgical intervention coupled with coordinated efforts by all members of the trauma team resulted in a positive outcome for this patient.

General surgeons, orthopedists, and pulmonologists individually treat patients with thoracic insufficiency syndrome (TIS). The benefits of growth-sparing procedures such as Vertical Expandable Prosthetic Titanium Rib (VEPTR)insertionfor treating patients with TIS have been demonstrated. However, at present there is no objective assessment metricto examine different thoracic structural components individually as to their roles in the syndrome, in contributing to dynamics and function, and in influencing treatment outcome. Using thoracic dynamic MRI (dMRI), we have been developing a methodology to overcome this problem. In this paper, we extend this methodology from our previous structural analysis approaches to examining lung tissue properties. We process the T2-weighted dMRI images through a series of steps involving 4D image construction of the acquired dMRI images, intensity non-uniformity correction and standardization of the 4D image, lung segmentation, and estimation of the parameters describing lung tissue intensity distributions in the 4D image. Based on pre- and post-operative dMRI data sets from 25 TIS patients (predominantly neuromuscular and congenital conditions), we demonstrate how lung tissue can be characterized by the estimated distribution parameters. Our results show that standardized T2-weighted image intensity values decrease from the pre- to post-operative condition, likely reflecting improved lung aeration post-operatively. In both pre- and post-operative conditions, the intensity values decrease also from end-expiration to end-inspiration, supporting the basic premise of our results.

Imaging of thoracic aortic dissection

Acute thoracic aortic dissection has a high mortality rate if untreated, so the diagnosis must be rapidly made. Multiple imaging techniques are often used. This retrospective study from 1988 to 1993 assesses the usefulness in diagnosis of chest X-rays, computed tomography (CT) scanning, aortography, magnetic resonance imaging (MRI), trans-thoracic (TTE) and trans-oesophageal (TOE) echocardiography. Forty-two patients with a final clinical diagnosis of dissection were studied. The diagnosis was confirmed in 16 (13 at surgery and three at autopsy). Three died with dissection given as the only cause of death. Chest X-ray abnormalities were seen in all 19 patients with surgery or death from dissection, with a widened mediastinum and/or dilated aorta being present in 17. In the group of 16 patients with surgery or autopsy proof, CT scans found dissections in 9 out of 12 patients studied and correctly classified the type in only five. Aortography was preformed in five, with accurate depiction of dissection and type in all. TTE found dissections in three of eight patients imaged by this method. MRI and TOE were preformed each on two patients, with accurate depiction of dissection and type in each. Because of the relatively low sensitivity of CT scanning in defining aortic dissections Westmead Hospital is currently assessing the use of TOE as the prime imaging modality prior to surgical intervention. 17 refs., 4 tabs., 4 figs

Mannose-binding lectin genotypes: lack of association with susceptibility to thoracic empyema

Moore Catrin E

2010-01-01

Full Text Available Abstract Background The role of the innate immune protein mannose-binding lectin (MBL in host defence against severe respiratory infection remains controversial. Thoracic empyema is a suppurative lung infection that arises as a major complication of pneumonia and is associated with a significant mortality. Although the pathogenesis of thoracic empyema is poorly understood, genetic susceptibility loci for this condition have recently been identified. The possible role of MBL genotypic deficiency in susceptibility to thoracic empyema has not previously been reported. Methods To investigate this further we compared the frequencies of the six functional MBL polymorphisms in 170 European individuals with thoracic empyema and 225 healthy control individuals. Results No overall association was observed between MBL genotypic deficiency and susceptibility to thoracic empyema (2 × 2 Chi square = 0.02, P = 0.87. Furthermore, no association was seen between MBL deficiency and susceptibility to the Gram-positive or pneumococcal empyema subgroups. MBL genotypic deficiency did not associate with progression to death or requirement for surgery. Conclusions Our results suggest that MBL genotypic deficiency does not associate with susceptibility to thoracic empyema in humans.

Objective: To compare the efficacy of British Thoracic Society and American Thoracic Society guidelines for re-introduction of anti-tuberculous therapy after drug-induced liver injury, and to assess the ease of administration of each guideline on a scale of 1-10. Methods: The randomised prospective interventional study was conducted at the Department of Medicine and Pulmonology, Dow University of Health Sciences, Karachi, from December 2011 to November 2013. Patients with anti-tuberculous therapy drug-induced liver injury were selected. Hepatotoxic anti-tuberculous therapy was stopped and modified anti-tuberculous therapy was started. Patients were followed weekly till clinical and biochemical parameters got stabilised. After stabilisation, the patients were randomised to one of the two groups to receive re-introduction of anti-tuberculous therapy under the guidelines of British Thoracic Society (Group I) or those of American Thoracic Society (Group II). Means of the groups were analysed by Student's t test and proportions were compared by chi-square test. Multivariate analysis was done for age, body mass index and serum albumin for recurrence of drug-induced liver injury after the re-introduction. P value <0.05 was taken as significant. Results: Of the total 325 patients, 163(50.15%) were in Group I, while 162(49.84%) were in Group II. The frequency of recurrence of drug-induced liver injury in Group I was 16 (9.8%) and in Group II it was 18 (11.1%). There was no statistically significant difference between the two groups (p<0.7). Age was positively related with drug-induced liver injury, while body mass index and serum albumin were negatively associated. Conclusion: There was no significant difference between the two major guidelines though the American Thoracic Society guideline was easier to follow. (author)

Jeune syndrome is a rare congenital malformation with a reported incidence of 1 in 100,000–130,000 live births. Thoracic hypoplasia is the most striking abnormality of this disorder. Here we report a case of Jeune syndrome with marked thoracic hypoplasia, micromelia and facial dysmorphism, which was diagnosed on a second-trimester antenatal real-time three-dimensional ultrasound. A 24-year-old primigravida came for routine anomaly scan at 19 weeks of gestation. Transabdominal grey scale and real time 3D ultrasound (US) was done with GE Logiq P5 with curvilinear array transducers (4C and 4D3C-L). US findings were consistent with the diagnosis of Jeune syndrome (Asphyxiating thoracic dysplasia). Jeune syndrome is an extremely rare congenital disorder with a spectrum of abnormalities of which thoracic hypoplasia is the most striking. It can be diagnosed on early antenatal US by its characteristic skeletal and morphological features which can guide further management of pregnancy in form of termination or preparation for surgical correction of the deformity

The chimney technique can be combined with thoracic endovascular aortic repair (TEVAR) to both obtain an appropriate landing zone and maintain blood flow of the arch vessels. However, surgical repair becomes more complicated if retrograde type A aortic dissection occurs after TEVAR with the chimney technique. We herein report a case involving a 73-year-old woman who developed a retrograde ascending dissection 3 months after TEVAR for acute type B aortic dissection. To ensure an adequate proximal sealing distance, the proximal edge of the stent graft was located at the zone 2 level and an additional bare stent was placed at the left subclavian artery (the chimney technique) at the time of TEVAR. Enhanced computed tomography revealed an aortic dissection involving the ascending aorta and aortic arch. Surgical aortic repair using the frozen elephant trunk technique was urgently performed. The patient survived without stroke, paraplegia, renal failure, or other major complications. Retrograde ascending dissection can occur after TEVAR combined with the chimney technique. The frozen elephant trunk technique is useful for surgical repair in such complicated cases.

Objective: To provide a reference for determination of the postoperative radiotherapy target volume for thoracic esophageal squamous cell carcinoma. Background data: The irradiation target volume is important for effective postoperative treatment of thoracic esophageal squamous cell carcinoma. Methods: One hundred forty patients with recurrent or metastatic thoracic esophageal squamous cell carcinoma who had been treated with radical surgery but not with postoperative radiotherapy were enrolled in this study. The information of locoregional recurrence and distant metastasis for these patients was analyzed. Results: The median time to progression in the 140 patients with recurrence or metastasis was 18.3 months (range 15.4-21.1 months). Anastomotic recurrence accounted for 13.6% of treatment failures. The supraclavicular and station 1-5 and 7 lymph nodes had high metastasis rates for esophageal squamous cell carcinomas in all locations. The order from highest to lowest metastasis rate for the station 3 and 4 lymph nodes was middle, upper and lower thoracic esophageal regions and the order for upper abdominal lymph nodes was lower, middle, and upper thoracic esophageal regions. Locoregional recurrence was the most common type of recurrence. Conclusions: For upper and middle thoracic esophageal squamous cell carcinomas, the anastomosis, supraclavicular, and station 1-5 and 7 lymph nodes should be delineated as the postoperative prophylactic irradiation target volume with upper abdominal lymph nodes excluded; for lower thoracic esophageal squamous cell carcinomas, anastomosis, supraclavicular, station 1-5 and 7 lymph nodes and upper abdominal lymph nodes should be delineated as the postoperative prophylactic irradiation target volume.

Full Text Available The red panda (Ailurus fulgens is distributed primarily in the Himalayas and southern China. It is classified as a vulnerable species by the International Union for Conservation of Nature. The aim of this study was to describe the normal osteology and radiographic anatomy of the thoracic limb of the red panda. Radiography of the right thoracic limb was performed in seven captive adult red pandas. Radiographic findings were correlated with bone specimens from three adult animals. The scapula was wide craniocaudally and presented with a large area for the origin of the teres major muscle. The square-shaped major tubercle did not extend proximal to the head of the humerus. The medial epicondyle was prominent. A supracondylar foramen was present. The radial tuberosity and sesamoid bone for the abductor digiti I longus were prominent. The accessory carpal bone was directed palmarolaterally. Metacarpal bones were widely spread. The thoracic limb morphology of the red panda evidenced by osteology and radiography indicated flexibility of the thoracic limb joints and well-developed flexor and supinator muscles, which are important in arboreal quadrupedal locomotion. Knowledge gained during this study may prove useful in identifying skeletal material or remains and diagnosing musculoskeletal diseases and injuries of the thoracic limb.

Thoracic neuroblastoma accounts for 15% of all cases of neuroblastoma. A minority of children with thoracic neuroblastoma will have dumbbell tumors, i.e., intraspinal extension, but only half these patients will have neurologic signs or symptoms. Hypothesis. MR imaging is the single best test to evaluate the extent of thoracic and spinal disease in thoracid neuroblastoma after the diagnosis of a mass is estbalished on plain film. A retrospective multi-institutional investigation over 7 years of all cases of thoracic neuroblastoma (n=26) imaged with CT and/or MR were reviewed for detection of the extent of disease. The chest film, nuclear bone scan, and other imaging modalities were also reviewed. The surgical and histologic correlation in each case, as well as the patients' staging and outcome, were tabulated. The chest radiography was 100% sensitive in suggesting the diagnosis. MR imaging was 100% sensitive in predicting enlarged lymph nodes, intraspinal extension, and chest wall involvement. CT was 88% sensitive for intraspinal extension but only 20% sensitive for lymph node enlargement. CT was 100% sensitive in detecting chest wall involvement. Direct comparison of CT and MR imaging in six cases revealed no difference in detection of enlarged lymph nodes or chest wall involvement. Neither test was able to detect remote disease, as noted by bone scan. The chest film is 100% sensitive in suggesting the diagnosis of thoracic neuroblastoma; MR imaging appears to be the single best test for detecting nodal involvement, intraspinal extension, and chest wall involvement.

Treatment for rib fracture pain can be broadly divided into pharmacologic approaches with oral and/or parenteral medication and interventional approaches utilizing neuraxial analgesia or peripheral nerve blocks to provide pain relief. Both approaches attempt to control nociceptive and neuropathic pain secondary to osseous injury and nerve insult, respectively. Success of treatment is ultimately measured by the ability of the selected modality to decrease pain, chest splinting, and to prevent sequelae of injury, such as pneumonia. Typically, opioids and NSAIDs are the drugs of first choice for acute pain because of ease of administration, immediate onset of action, and rapid titration to effect. In contrast, neuropathic pain medications have a slower onset of action and are more difficult to titrate to therapeutic effect. Interventional approaches include interpleural catheters, intercostal nerve blocks, paravertebral nerve blocks, and thoracic and lumbar epidural catheters. Each intervention has its own inherent advantages, disadvantages, and success rates. Rib fracture pain management practice is founded on the thoracic surgical and anesthesiology literature. Articles addressing rib fracture pain are relatively scarce in the pain medicine literature. As life expectancy increases, and as healthcare system modifications are implemented, pain medicine physicians may be consulted to treat increasing number of patients suffering rib fracture pain and may need to resort to novel therapeutic measures because of financial constraints imposed by those changes. Here we present the first published case series of thoracic epidural steroid injections used for management of rib fracture pain. © 2012 The Authors Pain Practice © 2012 World Institute of Pain.

Objective: To describe the surgical repair and pre- and postoperative management of a peritoneopericardial diaphragmatic hernia (PPDH) in a pregnant dog. Case summary: A pregnant dog was presented for vomiting, lethargy, and pale mucous membranes. Pulsus paradoxus was noted on physical examination. The dog was diagnosed with a PPDH via thoracic radiographs, abdominal ultrasound, and a n echocardiogram. The hernia was surgically repaired and the dog received supportive medical care until the puppies were old enough to be delivered via cesarean section. The mother and all puppies survived. New or unique information provided: This is the first report that describes the surgical repair and postoperative management of a PPDH in a pregnant dog

A "conservative" method of thoracic wall dissection: a proposal for teaching human anatomy.

Barberini, Fabrizio; Brunone, Francesca

The common methods of dissection exposing the thoracic organs include crossing of the wall together with wide resection of its muscular planes. In order to preserve these structures, a little demolishing technique of the thoracic wall is proposed, entering the thoracic cavity without extensive resection of the pectoral muscles. This method is based on the fact that these muscles rise up from the wall, like a bridge connecting the costal plane with the upper limb, and that the pectoralis major shows a segmental constitution. SUPERIOR LIMIT: Resect the sternal manubrium transversely between the 1st and the 2nd rib. The incision is prolonged along the 1st intercostal space, separating the first sterno-costal segment of the pectoralis major from the second one, and involving the intercostal muscles as far as the medial margin of the pectoralis minor. This muscle must be raised up, and the transverse resection continued below its medial margin latero-medially along the 1st intercostal space, to rejoin the cut performed before. Then, the incision of the 1st intercostal space is prolonged below the lateral margin of the pectoralis minor, which must be kept raised up, medio-laterally as far as the anterior axillary line. INFERIOR LIMIT: It corresponds to the inferior border of the thoracic cage, resected from the xiphoid process to the anterior axillary line, together with the sterno-costal insertions of the diaphragm. Then, an incision of the sterno-pericardial ligaments and a median sternotomy from the xiphoid process to the transverse resection of the manubrium should be performed. LATERAL LIMIT: From the point of crossing of the anterior axillary line with the inferior limit, resect the ribs from the 10th to the 2nd one. The lateral part of the pectoralis major must be raised up, so that the costal resection may be continued below it. Then, at the lateral extremity of the superior incision, the first and the second sternocostal segment of the pectoralis major must be

The aim of this study was to assess the influence of thoracic anterior radiculomedullary artery (tARMA) distribution on spinal cord perfusion in a thoracic aortic surgical model. Twenty-six pigs (34 ± 3 kg; study group, n = 20; sham group, n = 6) underwent ligation of the left subclavian artery and thoracic segmental arteries. End points were spinal cord perfusion pressure (SCPP), regional spinal cord blood flow (SCBF), and neurologic outcome with an observation time of 3 hours. tARMA distribution patterns tested for an effect on end points included (1) maximum distance between any 2 tARMAs within the treated aortic segment (0 or 1 segment = small-distance group; >1 segment = large-distance group) and (2) distance between the end of the treated aortic segment and the first distal tARMA (at the level of the distal simulated stent-graft end = group 0; gap of 1 or more segments = group ≥1). The number of tARMA ranged from 3 to 13 (mean, 8). In the large-distance group, SCBF dropped from 0.48 ± 0.16 mL/g/min to 0.3 ± 0.08 mL/g/min (p distribution patterns of tARMAs correlate with the degree of SCBF drop and insufficient reactive parenchymal hyperemia in aortic procedures. Individual ARMA distribution patterns along the treated aortic segment could help us predict the individual risk of spinal ischemia. Copyright © 2017 The Society of Thoracic Surgeons.

2015-01-01

Full Text Available Persistent posttraumatic CSF fluid leakage may present a challenge to manage. Failure to address the leakage may result in complications such as meningitis, septicemia, radiculopathy, muscle weakness, and back pains. While the majority of the leakages may be managed conservatively, large dura defects as a result of gunshot wounds or motor vehicle accidents are best managed by surgical interventions. This may range from primary closure of the defect to fascial grafts, adhesive glues, and flaps. We present our experience with the use of flaps in a patient who had sustained such wounds in the thoracic spine. An island latissimus dorsal flap and a perforator fasciocutaneous flap were used to close the defect. Postoperatively the patient recovered well and the wounds healed without any complications.

Background  Congenital diaphragmatic hernia (CDH) is fatal in severe cases of pulmonary hypoplasia. We experienced a fatal case of pulmonary hypoplasia due to CDH, thoracic myelomeningocele (MMC), and thoracic dysplasia. This constellation of anomalies has not been previously reported. Case Report  A male infant with a prenatal diagnosis of thoracic MMC with severe hydrocephalus and scoliosis was born at 36 weeks of gestation. CDH was found after birth and the patient died of respiratory failure due to pulmonary hypoplasia and persistent pulmonary hypertension of the newborn at 30 hours of age despite neonatal intensive care. An autopsy revealed a left CDH without herniation of the liver or stomach into the thoracic cavity, severe hydrocephalus, Chiari malformation type II, MMC with spina bifida from Th4 to Th12, hemivertebrae, fused ribs, deformities of the thoracic cage and legs, short trunk, and agenesis of the left kidney. Conclusion  We speculate that two factors may be associated with the severe pulmonary hypoplasia: decreased thoracic space due to the herniation of visceral organs caused by CDH and thoracic dysplasia due to skeletal deformity and severe scoliosis.

Minimally invasive surgery attracts more and more attention because of the advantages of minimal trauma, less bleeding and pain and low complication rate. However, minimally invasive surgery for beating hearts is still a challenge. Our goal is to develop a soft robot surgical system for single-port minimally invasive surgery on a beating heart. The soft robot described in this paper is inspired by the octopus arm. Although the octopus arm is soft and has more degrees of freedom (DOFs), it can be controlled flexibly. The soft robot is driven by cables that are embedded into the soft robot manipulator and can control the direction of the end and middle of the soft robot manipulator. The forward, backward and rotation movement of the soft robot is driven by a propulsion plant. The soft robot can move freely by properly controlling the cables and the propulsion plant. The soft surgical robot system can perform different thoracic operations by changing surgical instruments. To evaluate the flexibility, controllability and reachability of the designed soft robot surgical system, some testing experiments have been conducted in vivo on a swine. Through the subxiphoid, the soft robot manipulator could enter into the thoracic cavity and pericardial cavity smoothly and perform some operations such as biopsy, ligation and ablation. The operations were performed successfully and did not cause any damage to the surrounding soft tissues. From the experiments, the flexibility, controllability and reachability of the soft robot surgical system have been verified. Also, it has been shown that this system can be used in the thoracic and pericardial cavity for different operations. Compared with other endoscopy robots, the soft robot surgical system is safer, has more DOFs and is more flexible for control. When performing operations in a beating heart, this system maybe more suitable than traditional endoscopy robots.

Surgical treatment of chest instability

Fractures of the ribs is the most common thoracic injury after blunt trauma. Chest wall instability (flail chest) is a common occurrence in the presence of multiple ribs fracture. Unilateral or bilateral fractures more ribs anteriorly or posteriorly will produce enough instability that paradoxical respiratory motion results in hypoventilation of an unacceptable degree. Open approach and surgical stabilisation of the chest preserved pulmonary function, improved pain control, minimized posttraumatic deformities and shorter back to work time. (author)

The number of men undergoing cosmetic surgery is increasing in North America. To determine the incidence and risk factors of major complications in males undergoing cosmetic surgery, compare the complication profiles between men and women, and identify specific procedures that are associated with higher risk of complications in males. A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Gender specific procedures were excluded. Primary outcome was occurrence of a major complication in males requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis evaluated potential risk factors for major complications including age, body mass index (BMI), smoking, diabetes, type of surgical facility, type of procedure, and combined procedures. Of the 129,007 patients, 54,927 underwent gender nonspecific procedures, of which 5801 (10.6%) were males. Women showed a higher mean age (46.4 ± 14.1 vs 45.2 ± 16.7 years, P procedures (RR 3.47), and combined procedures (RR 2.56). Aesthetic surgery in men is safe with low major complication rates. Modifiable predictors of complications included BMI and combined procedures.

To analyze and summarize the clinical features and experience in surgical treatment of deep sternal infection (DSWI). This was a retrospective study. From January 2008 to December 2013, 189 patients with secondary DSWI after cardiac surgery underwent the pectoralis major muscle flap transposition in our department. There were 116 male and 73 female patients. The mean age was (54 ± 21) years, the body mass index was (26. 1 ± 1. 3) kg/m2. The incidence of postoperation DSWI were after isolated coronary artery bypass grafting (CABG) in 93 patients, after other heart surgery plus CABG in 13 patients, after valve surgery in 47 patients, after thoracic aortic surgery in 16 patients, after congenital heart disease in 18 patients, and after cardiac injury in 2 patients. Clean patients' wound and extract secretions, clear the infection thoroughly by surgery and select antibiotics based on susceptibility results, and then repair the wound with appropriate muscle flap, place drain tube with negative pressure. Of all the 189 patients, 184 used isolate pectoralis, 1 used isolate rectus, and 4 used pectoralis plus rectus. The operative wounds of 179 patients were primary healing (94. 7%). Hospital discharge was postponed by 1 week for 7 patients, due to subcutaneous wound infection. Subcutaneous wound infection occurred again in 8 patients 1 week after hospital discharge, and their wounds healed after wound dressing. Nine patients (4. 7%) did not recover, due to residue of the sequestrum and costal chondritis, whom were later cured by undergoing a second treatment of debridement and pectoralis major muscle flap transposition. Eight patients died, in which 2 died of respiratory failure, 2 died of bacterial endocarditis with septicemia, 2 died of renal failure, 1 died of intraoperative bleeding leading to brain death and the 1 died of heart failure. The mortality rate was 4. 2% . The average length of postoperative hospital stay was (14 ± 5) days. The longest postoperative

The treatment of thoracic aortic disease has changed radically with the advances made in endovascular therapy since the concept of thoracic endovascular aortic repair was first described 15 years ago. Currently, there is a diverse array of endografts that are commercially available to treat the thoracic aorta. Multiple studies, including industry-sponsored and single-institution reports, have demonstrated excellent outcomes of thoracic endovascular aortic repair for the treatment of thoracic aortic aneurysms, with less reported perioperative morbidity and mortality in comparison with conventional open repair. Additionally, similar outcomes have been demonstrated for the treatment of type B dissections. However, the technology remains relatively novel, and larger studies with longer term outcomes are necessary to more fully evaluate the role of endovascular therapy for the treatment of thoracic aortic disease. This review examines the currently available thoracic endografts, preoperative planning for thoracic endovascular aortic repair, and outcomes of thoracic endovascular aortic repair for the treatment of both thoracic aortic aneurysms and type B aortic dissections.

Two patients with spontaneous epidural hematoma of the thoracic spine are presented. The magnetic resonance (MR) examination performed within the first hours following the onset of symptoms demonstrated an epidural elongated lesion impinging on the spinal cord, compatible with hematoma. In one of the patients this finding was surgically confirmed. The second patient improved under steroid treatment. The MR findings were highly suggestive of the pathological nature of the lesion. The MR examination should replace other diagnostic procedures, such as computerised tomography (CT) and myelography. (orig.)

Iatrogenic flattening of lumbar lordosis in patients with adolescent idiopathic scoliosis (AIS) was a major downside of first generation instrumentation. Current instrumentation systems allow a three-dimensional scoliosis correction, but flattening of lumbar lordosis remains a significant problem which is associated with decreased health-related quality of life. This study sought to identify risk factors for loss of lumbar lordosis in patients who had surgical correction of AIS with the use of segmental instrumentation. Patients were included if they had surgical correction for AIS with segmental pedicle screw instrumentation Lenke type 1 or 2 and if they had a minimum follow-up of 24 months. Two groups were created, based on the average loss of lumbar lordosis. The two groups were then compared and multivariate analysis was performed to identify parameters that correlated to loss of lumbar lordosis. Four hundred and seventeen patients were analyzed for this study. The average loss of lumbar lordosis at 24 months follow-up was an increase of 10° lordosis for group 1 and a decrease of 15° for group 2. Risk factors for loss of lumbar lordosis included a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and the particular operating surgeon. The lowest instrumented vertebra or spinopelvic parameters were two of many parameters that did not seem to influence loss of lumbar lordosis. This study identified important risk factors for decrease of lumbar lordosis in patients who had surgical treatment for AIS with segmental pedicle screw instrumentation, including a high preoperative lumbar lordosis, surgical decrease of thoracic kyphosis, and factors attributable to a particular operating surgeon that were not quantified in this study.

Thoracic hyperextension injury with complete “bony disruption” of the thoracic cage: Case report of a potentially life-threatening injury

Directory of Open Access Journals (Sweden)

Bailey James

2012-05-01

Full Text Available Abstract Background Severe chest wall injuries are potentially life-threatening injuries which require a standardized multidisciplinary management strategy for prevention of posttraumatic complications and adverse outcome. Case presentation We report the successful management of a 55-year old man who sustained a complete “bony disruption” of the thoracic cage secondary to an “all-terrain vehicle” roll-over accident. The injury pattern consisted of a bilateral “flail chest” with serial segmental rib fractures, bilateral hemo-pneumothoraces and pulmonary contusions, bilateral midshaft clavicle fractures, a displaced transverse sternum fracture with significant diastasis, and an unstable T9 hyperextension injury. After initial life-saving procedures, the chest wall injuries were sequentially stabilized by surgical fixation of bilateral clavicle fractures, locked plating of the displaced sternal fracture, and a two-level anterior spine fixation of the T9 hyperextension injury. The patient had an excellent radiological and physiological outcome at 6 months post injury. Conclusion Severe chest wall trauma with a complete “bony disruption” of the thoracic cage represents a rare, but detrimental injury pattern. Multidisciplinary management with a staged timing for addressing each of the critical injuries, represents the ideal approach for an excellent long-term outcome.

Muscle sparing lateral thoracotomy: the standard incision for thoracic procedures

Directory of Open Access Journals (Sweden)

Mihai Dumitrescu

2017-05-01

Full Text Available Lateral thoracotomy is a versatile approach with many variations and is currently the most widely used incision in thoracic surgery. In the current article we are presenting the muscle-sparing lateral thoracotomy in the lateral decubitus position which we consider to be the “standard” for lateral thoracotomies. Indications, surgical technique and pitfalls are described alongside our experience with thoracic drainage. Although there is no consensus regarding the name of this incision, some authors call it “axillary thoracotomy” while others call it a “modified lateral thoracotomy”, they all agree on one aspect – the importance of muscle sparing – which makes it the go-to thoracotomy for both small and large procedures involving the lung. Lateral muscle sparing thoracotomy allows for good exposure of the pulmonary hilum, fissures, apex and diaphragm. The approach is easy and quick to perform while at the same time ensuring faster postoperative recovery by sparing the latissimus dorsi muscle, better cosmetics and lower postoperative pain score when compared to the posterolateral or classical lateral thoracotomies.

Operating rooms in a high-volume thoracic surgery centre from September 2007 to June 2008. Thoracic surgery operating room teams. Two 90 min team-skills training sessions focused on findings from a standardised safety-culture survey administered to all participants and highlighting positive and problematic aspects of team skills, communication and leadership. Relationship of functional or less functional emotional climates of work to indices of threat to patient outcome. A less functional emotional climate corresponded to more threat to outcome in the sterile surgical environment in the pre-intervention period (pwork in the sterile surgical environment appeared to be related to threat to patient outcome prior to, but not after, a team-training intervention. Further study of the relationship between the emotional climate of work and threat to patient outcome using reproducible methods is required.

OBJECTIVE Sphenoid wing meningiomas are a heterogeneous group of tumors with variable surgical risks and prognosis. Those that have grown to a very large size, encasing the major cerebral arteries, are associated with a high risk of stroke. In reviewing the authors' series of giant sphenoid wing meningiomas, the goal was to evaluate how the extent of the tumor's invasion of surrounding structures affected the ability to safely remove the tumor and restore function. METHODS The authors conducted a retrospective study of a series of giant sphenoid wing meningiomas operated on between 1996 and 2016. Inclusion criteria were meningiomas with a globoid component ≥ 6 cm, encasing at least 1 major intradural cerebral artery. Extent of resection was measured according to Simpson grade. RESULTS This series included 12 patients, with a mean age of 59 years. Visual symptoms were the most common clinical presentation. There was complete or partial encasement of all 3 major cerebral arteries except for 3 cases in which only the anterior cerebral artery was not involved. The lateral wall of the cavernous sinus was invaded in 8 cases (67%) and the optic canal in 6 (50%). Complete resection was achieved in 2 cases (Simpson grades 2 and 3). In the remaining 10 cases of partial resection (Simpson grade 4), radical removal (> 90%) was achieved in 7 cases (70%). In the immediate postoperative period, there were no deaths. Four of 9 patients with visual deficits improved, while the 5 others remained unchanged. Two patients experienced transient neurological deficits. Other than an asymptomatic lacuna of the internal capsule, there were no ischemic lesions following surgery. Tumor recurrence occurred in 5 patients, between 24 and 168 months (mean 61 months) following surgery. CONCLUSIONS Although these giant lesions encasing major cerebral arteries are particularly treacherous for surgery, this series demonstrates that it is possible to safely achieve radical removal and at times even

Rib and sternal fracture repair are controversial. The opinion of surgeons regarding those patients who would benefit from repair is unknown. Members of the Eastern Association for the Surgery of Trauma, the Orthopedic Trauma Association, and thoracic surgeons (THS) affiliated with teaching hospitals in the United States were recruited to complete an electronic survey regarding rib and sternal fracture repair. Two hundred thirty-eight trauma surgeons (TRS), 97 orthopedic trauma surgeons (OTS), and 70 THS completed the survey. Eighty-two percent of TRS, 66% of OTS, and 71% of THS thought that rib fracture repair was indicated in selected patients. A greater proportion of surgeons thought that sternal fracture repair was indicated in selected patients (89% of TRS, 85% of OTS, and 95% of THS). Chest wall defect/pulmonary hernia (58%) and sternal fracture nonunion (>6 weeks) (68%) were the only two indications accepted by a majority of respondents. Twenty-six percent of surgeons reported that they had performed or assisted on a chest wall fracture repair, whereas 22% of surgeons were familiar with published randomized trials of the surgical repair of flail chest. Of surgeons who thought rib fracture or sternal fracture repair was rarely, if ever, indicated, 91% and 95%, respectively, specified that a randomized trial confirming efficacy would be necessary to change their negative opinion. A majority of surveyed surgeons reported that rib and sternal fracture repair is indicated in selected patients; however, a much smaller proportion indicated that they had performed the procedures. The published literature on surgical repair is sparse and unfamiliar to most surgeons. Barriers to surgical repair of rib and sternal fracture include a lack of expertise among TRS, lack of research of optimal techniques, and a dearth of randomized trials.

Pneumoscrotum as Complication of Blunt Thoracic Trauma: A Case Report

Directory of Open Access Journals (Sweden)

Eftychios Lostoridis

2013-01-01

Full Text Available Introduction. Pneumoscrotum is a rare clinical entity. It presents with swollen scrotal sac and sometimes with palpable crepitus. It has many etiologies. One of them is due to blunt trauma of the thoracic cage, causing pneumothorax and/or pneumomediastinum. Case Presentation. We report the case of an 82-year-old male who was transferred to the Emergency Department with signs of respiratory distress after a blunt chest trauma. A CT scan was obtained, and bilateral pneumothoraces with four broken ribs were disclosed. Subcutaneous emphysema expanding from the eyelids to the scrotum was observed, and a chest tube was inserted on the right side with immediate improvement of the vital signs of the patient. Discussion. Pneumoscrotum has three major etiologies: (a local introduction of air or infection from gas-producing bacteria, (b pneumoperitoneum, and (c air accumulation from lungs, mediastinum, or retroperitoneum. These sources account for most of the cases described in the literature. Treatment should be individualized, and surgical consultation should be obtained in all cases. Conclusion. Although pneumoscrotum itself is a benign entity, the process by which air accumulates in the scrotum must be clarified, and treatment must target the primary cause.

Management of chest trauma is integral to patient outcomes owing to the vital structures held within the thoracic cavity. Understanding traumatic chest injuries and appropriate management plays a pivotal role in the overall well-being of both blunt and penetrating trauma patients. Whether the injury includes rib fractures, associated pulmonary injuries, or tracheobronchial tree injuries, every facet of management may impact the short- and long-term outcomes, including mortality. This article elucidates the workup and management of the thoracic cage, pulmonary and tracheobronchial injuries. Copyright © 2017 Elsevier Inc. All rights reserved.

Surgical and nonsurgical treatment of total rupture of the pectoralis major muscle in athletes: update and critical appraisal.

Kircher, Jörn; Ziskoven, Christoph; Patzer, Thilo; Zaps, Daniela; Bittersohl, Bernd; Krauspe, Rüdiger

2010-10-11

The complete rupture of the pectoralis major tendon is an uncommon injury but has become increasingly common among athletes in recent years. This may be due to a higher number of individuals taking part in high-impact sports and weightlifting as well as the use of anabolic substances, which can make muscles and tendons vulnerable to injury. In recent literature, there are only few recommendations to rely on conservative treatment alone, but there are a number of reports and case series recommending early surgical intervention. Comparing the results of the two treatment regimens, there is clear evidence for a superior outcome after surgical repair with better cosmesis, better functional results, regaining of muscle power, and return to sports compared with the conservative treatment. In summary, anatomic surgical repair is the treatment of choice for complete acute ruptures of the pectoralis major tendon or muscle in athletes.

Study Design. A cadaveric laboratory study. Objective. The aim of this study was to assess the feasibility and accuracy of thoracic pedicle screw placement using augmented reality surgical navigation (ARSN). Summary of Background Data. Recent advances in spinal navigation have shown improved accuracy in lumbosacral pedicle screw placement but limited benefits in the thoracic spine. 3D intraoperative imaging and instrument navigation may allow improved accuracy in pedicle screw placement, without the use of x-ray fluoroscopy, and thus opens the route to image-guided minimally invasive therapy in the thoracic spine. Methods. ARSN encompasses a surgical table, a motorized flat detector C-arm with intraoperative 2D/3D capabilities, integrated optical cameras for augmented reality navigation, and noninvasive patient motion tracking. Two neurosurgeons placed 94 pedicle screws in the thoracic spine of four cadavers using ARSN on one side of the spine (47 screws) and free-hand technique on the contralateral side. X-ray fluoroscopy was not used for either technique. Four independent reviewers assessed the postoperative scans, using the Gertzbein grading. Morphometric measurements of the pedicles axial and sagittal widths and angles, as well as the vertebrae axial and sagittal rotations were performed to identify risk factors for breaches. Results. ARSN was feasible and superior to free-hand technique with respect to overall accuracy (85% vs. 64%, P dimensions, except for vertebral body axial rotation, were risk factors for larger breaches when performed with the free-hand method. Conclusion. ARSN without fluoroscopy was feasible and demonstrated higher accuracy than free-hand technique for thoracic pedicle screw placement. Level of Evidence: N/A PMID:27513166

The aim of this study was to determine cerebrovascular accident predictors after thoracic endovascular aortic repair. Between January 2001 and June 2008, 76 patients treated with thoracic endovascular aortic repair were prospectively enrolled. The study cohort included 61 men; mean age was 65.4 +/- 16.8 years. All patients underwent a specific neurologic assessment on an hourly basis postoperatively to detect neurologic deficits. Cerebrovascular accidents were diagnosed on the basis of physical examination, tomography scan or magnetic resonance imaging, or autopsy. Cerebrovascular accidents occurred in 8 (10.5%) patients, including 4 transient ischemic attack and 4 major strokes. Four cases were observed within the first 24-hours. Multivariable analysis revealed that anatomic incompleteness of the Willis circle (odds ratio [OR] 17.19, 95% confidence interval [CI] 2.10 to 140.66), as well as the presence of coronary artery disease (OR 6.86, 95 CI% 1.18 to 40.05), were independently associated with postoperative cerebrovascular accident development. Overall hospital mortality was 9.2%, with no significant difference for patients hit by cerebrovascular accidents (25.0% vs 7.3%, p = 0.102). Preexisting coronary artery disease, reflecting a severe diseased aorta and anomalies of Willis circle are independent cerebrovascular accident predictors after thoracic endovascular aortic repair procedures. A careful evaluation of the arch vessels and cerebral vascularization should be mandatory for patients suitable for thoracic endovascular aortic repair.

Transoral endoscopic surgery has been shown to be feasible and safe in both humans and animal models. The purpose of this study was to evaluate the safety and efficacy of transoral and conventional thoracoscopy for thoracic exploration, surgical lung biopsy, and pericardial window creation. The animals (n = 20) were randomly assigned to the transoral endoscopic approach group (n = 10) or conventional thoracoscopic approach group (n = 10). Transoral thoracoscopy was performed with a flexible bronchoscope via an incision over the vestibulum oris. In conventional thoracoscopy, access to the thoracic cavity was obtained through a thoracic incision. Surgical outcomes (body weight, operating time, operative complications, and time to resumption of normal diet), physiologic parameters (respiratory rate, body temperature), inflammatory parameters [white blood cell (WBC) counts and C-reactive protein (CRP)], and pulmonary parameters (arterial blood gases) were compared for both procedures. The surgical lung biopsy and pericardial window creation were successfully performed in all animals except one animal in the transoral group. There was no significant difference in operating times between the groups. The increase in WBC in the transoral thoracoscopy group was significantly smaller on postoperative day 1 than in the conventional thoracoscopy group (p = 0.0029). The transoral group had an earlier return to preoperative body temperature (p = 0.041) and respiratory rate (p = 0.045) on day 7. With respect to pulmonary parameters, there was no significant difference in blood pH, pCO2, or PaCO2 between the transoral and transthoracic groups. All animals survived without complications 14 days after surgery. This study demonstrated that the transoral approach was comparable to conventional thoracoscopic surgery for lung biopsy and pericardial window creation in terms of safety and efficacy.

Web-based curricula provide login data that can be advantageously used to characterize and analyze study habits. We sought to compare thoracic surgical trainee In-Training Examination percentiles with regard to their study habits (ie, cramming), as characterized by curriculum login frequency to the national Web-based Thoracic Surgery Curriculum. Furthermore, we then aimed to characterize the curriculum login frequency of trainees as stratified by their performance on the In-Training Examination and their improvement on the In-Training Examination over subsequent years. We performed a retrospective review of trainees who accessed the curriculum before the 2014 In-Training Examination, with curriculum login data collected from site analytics. Scores were compared between trainees who crammed (≥30% increase in logins in the month before the In-Training Examination) and those who did not. Trainees were stratified on the basis of 2014 In-Training Examination percentile and improvement in percentile from 2013 to 2014 into high, medium, and low scorers and improvers. Of 256 trainees who took the 2014 In-Training Examination, 63 (25%) met criteria as crammers. Crammers increased total study sessions immediately before the In-Training Examination (P < .001), but without impact on 2014 In-Training Examination percentile (P = .995) or year-to-year improvement (P = .234). Stratification by In-Training Examination percentile demonstrated that highest scoring trainees used the curriculum more frequently in the final month than medium-range scorers (P = .039). When stratified by extent of year-to-year improvement, those who improved the most accessed the curriculum significantly more often in the last month compared with baseline (P = .040). Moreover, those with greatest improvement logged in more in the final month than those with least improvement (P = .006). Increasing the frequency of study periods on the national Web-based thoracic surgery curriculum before the

Full Text Available Karl Reinhard Aigner, Emir Selak, Sabine Gailhofer Department of Surgical Oncology, Medias Klinikum, Burghausen, Germany Introduction: Therapy of malignant pleural mesothelioma and especially the adequate role of surgery in this context remain the subject of controversial discussions. Radical surgery in particular, which is associated with substantial morbidity, failed to translate into a definite survival advantage. We report on interim results of an ongoing Phase II study of regional chemotherapy in terms of isolated thoracic perfusion with chemofiltration (ITP-F.Patients and methods: Twenty-eight patients (25 male, 3 female, mean age 63.4 years with advanced pleural mesothelioma were included in this study. Isolation of the chest was achieved by insertion of a venous and arterial stop-flow balloon catheter via a femoral access. The aorta and inferior vena cava were blocked at the level of the diaphragm and the upper arms were blocked by pneumatic cuffs. Chemotherapy, consisting of 60 mg/m² cisplatin and 15 mg/m² mitoxantrone, was administered directly into the aorta. The isolated circuit was maintained for 15 minutes followed by ~45 minutes of chemofiltration with a hemoprocessor until 5 L of filtrate were reached. The endpoints of the study were overall survival and quality of life (QoL.Results: Out of 28 patients enrolled in the study, 5 had prior surgeries, 10 patients had systemic chemotherapy, and 5 patients additional irradiation. In all patients in restaging, clinical progress was noted. In all, 162 cycles were administered. Due to chemofiltration, toxicity was within tolerable limits, revealing World Health Organization grade I leucopenia and thrombocytopenia in 9 patients and mucositis grade I in 6 patients. The major surgical complication was inguinal lymphatic fistula in 40% of the cases. Gastrointestinal toxicity and/or neurotoxicity were never observed. One-year survival was 49%, 2-year and 3-year survival was 31%, and 5

To evaluate the effect of cisterna chyli ablation (CCA) and thoracic duct ligation (TDL) on abdominal lymphatic drainage in normal dogs. Experimental study. Nine female beagle dogs. TDL was performed in 3 dogs and was combined with CCA (CCA-TDL) and local omentalization in 6 dogs. Contrast lymphangiography was attempted in all dogs immediately before and after TDL. Dogs were reanesthetized at 31-37 days for lymphatic studies by new methylene blue (NMB) injection into a mesenteric lymph node and by contrast lymphangiography. In 6 CCA-TDL dogs, 2 had direct shunting of contrast from the lymphatic system into major abdominal veins, 3 had contrast material that dissipated into abdominal vessels within the mesenteric root, and 1 had shunting into the azygous vein. NMB was not observed within the omental pedicle after CCA-TDL. Chylous drainage was by the azygous vein in all 3 TDL dogs. CCA-TDL disrupted chylous drainage to the thoracic duct and resulted in direct intraabdominal lymphaticovenous anastomoses identified by shunting of lymphatic flow directly into the abdominal vasculature in 5 of 6 CCA-TDL dogs. Omentalization of the cisternal ablation site was not beneficial in augmenting extrathoracic lymphatic drainage and is not recommended with CCA-TDL. CCA-TDL represents a novel approach to surgical redirection of chylous drainage to the venous circulation outside of the thorax and may be useful in the treatment of spontaneous chylothorax in the dog.

Full Text Available Background: Bronchiectasis is defined as an abnormal and irreversible dilation and distortion of the bronchi, which has numerous causes. Surgical treatment of this disease is usually reserved for focal disease and when the medical treatment is no longer effective. We report our center experience and outcomes in bronchiectasis surgery during the last 20 years. Methods: Between 1994 and 2014, sixty-nine patients underwent surgical resection for bronchiectasis. Patient demographics, presenting symptoms, indications for surgical treatment, type of lung resection, morbidity and mortality, as well as clinical follow-up and outcomes were analyzed. Results: From the 69 patients included, 31 (44.9% were male and 38 (55.1% were female. Surgery was indicated because of unsuccessful medical therapy in 33 patients (47.8%, haemoptysis in 22 patients (31.9%, nondiagnostic lung mass in 9 patients (13.0% and lung abscess in 5 patients (7.3%. The surgical procedures were lobectomy in 45 (65.2% patients, pneumonectomy in 10 (14.5% patients, bilobectomy in 8 (11.6% patients, lobectomy plus segmentectomy in 3 (4.3% patients and only segmentectomy in 3 (4.3% patients. Morbidity rate was 14.5% and there was no perioperative mortality. The follow-up was possible in 60 patients, with an outcome reported as excellent in 44 (73.3% patients, as improved in 11 (18.3% and as unchanged in 5 (8.3%. Conclusion: Although the number of patients with bronchiectasis referred for surgical treatment has decreased, pulmonary resection still plays a significant role. Surgical resection of localized bronchiectasis is a safe procedure with proven improvement of quality of life for the majority of patients. Keywords: Bronchiectasis, Thoracic surgery

Canada's contributions toward the 21st century's practice of thoracic surgery have been both unique and multilayered. Scattered throughout are tales of pioneers where none had gone before, where opportunities were greeted by creativity and where iconic figures followed one another. To describe the numerous and important achievements of Canadian thoracic surgeons in the areas of surgery for pulmonary tuberculosis, thoracic oncology, airway surgery and lung transplantation. Information was collected through reading of the numerous publications written by Canadian thoracic surgeons over the past 100 years, interviews with interested people from all thoracic surgery divisions across Canada and review of pertinent material form the archives of several Canadian hospitals and universities. Many of the developments occurred by chance. It was the early and specific focus on thoracic surgery, to the exclusion of cardiac and general surgery, that distinguishes the Canadian experience, a model that is now emerging everywhere. From lung transplantation in chimera twin calves to ex vivo organ preservation, from the removal of airways to tissue regeneration, and from intensive care research to complex science, Canadians have excelled in their commitment to research. Over the years, the influence of Canadian thoracic surgery on international practice has been significant. Canada spearheaded the development of thoracic surgery over the past 100 years to a greater degree than any other country. From research to education, from national infrastructures to the regionalization of local practices, it happened in Canada.

To describe diagnostic findings, surgical technique, and outcome in dogs with thoracic spinal canal stenosis and vertebral instability secondary to congenital vertebral anomalies. Retrospective clinical study. Dogs (n=9) with thoracic spinal canal stenosis. Medical records (1995-1996; 2000-2006) of 9 dogs with a myelographic diagnosis of spinal canal stenosis and/or vertebral instability secondary to congenital vertebral anomaly that were surgically managed by vertebral stabilization with or without laminectomy were reviewed. Data on pre- and postoperative neurologic status, diagnostic findings, surgical techniques, and outcomes were retrieved. Follow-up evaluations were performed at 1, 2, and 6 months. Long-term outcome was assessed by means of clinical examination or owner telephone interviews. Spinal cord compression was confirmed by myelography, and in 2 dogs, dynamic compression by stress myelography. Eight dogs regained the ability to ambulate postoperatively. One dog with a partial recovery regained voluntary movement but did not become ambulatory. Spinal cord injury secondary to congenital vertebral anomaly may have a good outcome when treated by vertebral stabilization with or without laminectomy. Adequate stabilization of the vertebrae and improved neurologic outcome were achieved in most dogs. Vertebral stabilization using positively threaded profile pins and polymethylmethacrylate with or without laminectomy is an effective treatment for spinal canal stenosis and vertebral instability secondary to congenital thoracic vertebral anomalies.

Hybrid repair of a very late, post-aortic coarctation surgery thoracic aneurysm: a case report

2012-08-01

Full Text Available Abstract Introduction Local aneurysms after surgical repair of coarctation of the aorta occur mainly in patients surgically treated by Dacron patch plasty during adulthood. The management of these patients is always problematic, with frequent complications and increased mortality rates. Percutaneous stent-graft implantation avoids the need for surgical reintervention. Case presentation We report a case involving the hybrid treatment by stent-graft implantation and transposition of the left subclavian artery to the left common carotid artery of an aneurysmal dilatation of the thoracic aorta that occurred in a 64-year-old Caucasian man, operated on almost 40 years earlier with a Dacron patch plasty for aortic coarctation. Our patient presented to our facility for evaluation with back pain and shortness of breath after minimal physical effort. A physical examination revealed stony dullness to percussion of the left posterior thorax, with no other abnormalities. The results of chest radiography, followed by contrast-enhanced computed tomography and aortography, led to a diagnosis of giant aortic thoracic aneurysm. Successful treatment of the aneurysm was achieved by percutaneous stent-graft implantation combined with transposition of the left subclavian artery to the left common carotid artery. His post-procedural recovery was uneventful. Three months after the procedure, computed tomography showed complete thrombosis of the excluded aneurysm, without any clinical signs of left lower limb ischemia or new onset neurological abnormalities. Conclusions Our patient’s case illustrates the clinical outcomes of surgical interventions for aortic coarctation. However, the very late appearance of a local aneurysm is rather unusual. Management of such cases is always difficult. The decision-making should be multidisciplinary. A hybrid approach was considered the best solution for our patient.

Starting a robotic program in general thoracic surgery: why, how, and lessons learned.

We report our experience in starting a robotic program in thoracic surgery. We retrospectively reviewed our experience in starting a robotic program in general thoracic surgery on a consecutive series of patients. Between February 2009 and September 2010, 150 patients underwent robotic operations. Types of procedures were lobectomy in 62, thymectomy in 30, and benign esophageal procedures in 6. No thymectomy or esophageal procedures required conversion. One conversion was needed for suspected bleeding for a mediastinal mass. Twelve patients were converted for lobectomy (none for bleeding, 1 in the last 24). Median operative time for robotic thymectomy was 119 minutes, and median length of stay was 1 day. The median time for robotic lobectomy was 185 minutes, and median length of stay was 2 days. There were no operative deaths. Morbidity occurred in 23 patients (15%). All patients with cancer had R0 resections and resection of all visible mediastinal and hilar lymph nodes. Robotic surgery is safe and oncologically sound. It requires training of the entire operating room team. The learning curve is steep, involving port placement, availability of the proper instrumentation, use of the correct robotic arms, and proper patient positioning. The robot provides an ideal surgical approach for thymectomy and other mediastinal tumors. Its advantage over thoracoscopy for pulmonary resection is unproven; however, we believe complete thoracic lymph node dissection and teaching is easier. Importantly, defined credentialing for surgeons and cost analysis studies are needed. Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Cord Compression due to Extramedullary Hematopoiesis in an Adolescent with Known Beta Thalassemia Major

We describe a 16 year-old male with β thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH). After treatment with steroids, radiotherapy and monitored blood transfusions, the patient demonstrated significant improvement of his paraspinal lesions and near complete resolution of his neurological symptoms. While EMH causing cord compression in adolescents is rare in the current era of bone marrow transplantation or chronic transfusions, it should be considered when thalassemia major patients present with neurological deficits. The well defined imaging features of EMH can play a central role in its diagnosis and management, especially because surgical and / or radiotherapeutic intervention are often considered in cases of failed medical treatment.

During urological surgical procedures with fluoroscopy, the doses of the care team may be significant. However, the knowledge of the occupational exposure of these professionals is still very incipient in the national surgical centers. The objective of the study is to determine the isodose curves of the urological surgical procedures, in order to estimate the exposure of the personnel involved. The equipment used was a Arco-C BV Philips Bracelet. Patients with thicknesses of 20 and 28 cm were simulated using acrylic plates. The dose rates were measured with RaySafe i2 Unfors dosimeters positioned in a 50 x 50 cm mesh at three different heights of the floor: 95, 125 and 165 centimeters respectively corresponding to the gonadal, thoracic and crystalline regions of a typical adult . The isodose curves applied to the distribution of the surgical team suggest that the exposures are in the following descending order of intensity: primary physician, auxiliary physician, scrub nurse, anesthetist and nurse

The application of Robotic technology in thoracic surgery has become widespread in the last decades. Thanks to its advanced features, the robotic system allows to perform a broad range of complex operations safely and in a comfortable way, with valuable advantages related to low invasiveness. Regarding lung tumours, several studies have shown the benefits of robotic surgery including lower blood loss and improved lymph node removal when compared with other minimally invasive techniques. Moreover, the robotic instruments allow to reach deep and narrow spaces permitting safe and precise removal of tumours located in remote areas, such as retrosternal and posterior mediastinal spaces with outstanding postoperative and oncological results. One controversial finding about the application of robotic system is its high capital and running costs. For this reason, a limited number of centres worldwide are able to employ this groundbreaking technology and there are limited possibilities for the trainees to acquire the necessary skills in robotic surgery. Therefore, a training programme based on three steps of learning, associated with a solid surgical background and a consistent operating activity, are required to obtain effective results. Putting this highest technological innovation in the hand of expert surgeons we can assure safe and effective procedures getting the best from robotic thoracic surgery.

Severe thoracic sarcoidosis includes manifestations with significant clinical and functional impairment and a risk of mortality. Severe thoracic sarcoidosis can take on various clinical presentations and is associated with increased morbidity. The purpose of this article was to describe the CT findings in severe thoracic sarcoidosis and to explain some of their mechanisms. Subacute respiratory insufficiency is a rare and early complication due to a high profusion of pulmonary lesions. Chronic respiratory insufficiency due to pulmonary fibrosis is a frequent and late complication. Three main CT patterns are identified: bronchial distortion, honeycombing and linear opacities. CT can be helpful in diagnosing some mechanisms of central airway obstruction such as bronchial distortion due to pulmonary fibrosis or an extrinsic bronchial compression by enlarged lymph nodes. An intrinsic narrowing of the bronchial wall by endobronchial granulomatous lesions may be suggested by CT when it shows evidence of bronchial mural thickening. Pulmonary hypertension usually occurs in patients with end-stage pulmonary disease and is related to fibrotic destruction of the distal capillary bed and to the resultant chronic hypoxemia. Several other mechanisms may contribute to the development of pulmonary hypertension including extrinsic compression of major pulmonary arteries by enlarged lymph nodes and secondary pulmonary veno-occlusive disease. Aspergilloma colonization of a cavity is the main cause of hemoptysis in sarcoidosis. Other rare causes are bronchiesctasis, necrotizing bronchial aspergillosis, semi-invasive pulmonary aspergillosis, erosion of a pulmonary artery due to a necrotic sarcoidosis lesion, necrosis of parenchymal sarcoidosis lesions and specific endobronchial macroscopic lesions.

To evaluate the incidence and angiographic findings of the collateral pathway involving the internal thoracic artery in patients with chronic aortoiliac occlusive disease. Between March 2000 and Februrary 2001, 124 patients at our hospital underwent angiographic evaluation of chronic aortoiliac occlusive disease, and in 15 of these complete obstruction or severe stenosis of the aortoiliac artery was identified. The aortograms and collateral arteriograms obtained, including internal thoracic arteriograms, as well as the medical records of the patients involved, were evaluated. In nine patients there was complete occlusion of the infrarenal aorta, or diffuse stenosis of 75% or more in the descending thoracic aorta, and in the other six, a patent aorta but complete occlusion or stenosis of 75% or more of the common iliac artery was demonstrated. Collateral perfusion via hypertrophied internal thoracic arteries and rich anastomoses between the superior and inferior epigastric arteries, reconstituting the external iliac artery, were noted in all fifteen patients, regardless of symptom duration, which ranged from six months to twelve years. In patients with chronic aortoiliac occlusive disease, the internal thoracic artery, along with visceral collaterals and those from the contralateral side, is one of the major parietal collateral pathways

Esophagus cancer represents a very lethal neoplasm. Esophageal resection is going to be the therapeutic alternative to patients considered surgical candidates. It had been described some esophagus resection procedure. Although, there is not any agreement between surgeon about which are best procedure to patients with esophagus carcinoma. Most of patients who came advanced phase have poor prognostic and only patients, who have illness in early stage, exist expectative to improve survival with lymphadenectomy extended and neoadjuvant. We analyzes retrospectively files of 23 patients submitted to esophagectomy in hospital Solca Quito from 1985 to 2004 with the diagnostic of esophagus carcinoma, considering histology type, location, surgical proceeded, pathologic staging, surgical mortally, mobility and survival time live. Also it makes a review about proceeds of esophagus resection and adjuvant therapy to the esophagus cancer. Conclusions: Esophagectomy transhiatal has limitations in oncological resection and recommend it early lower esophagus lesions and cardiac orifice (dysplasia high grade, T is, TI, NO, MO) in patients of high risk. Right trans thoracic esophagectomy it is considered in all lesions advanced locally lower middle third, and cardias orifice with lymphadenectomy of two areas and have avoid of trans thoracic anastomotic risk. Trans operatively margins upper have been 10 cm and 5 cm distal, always freeze those margins trans operatively. Extended lymphadenectomy to three areas we have no order yet conclusive dates and the chemotherapy neoadjuvant had been a positive impact in the survival in those chemosensitive tumors with appropriate answer and could be totally remove, but randomized testing future could determine his efficacy real.

To compare early and mid-term outcomes after repair of extensive aneurysm of the thoracic aorta using the conventional elephant trunk or frozen elephant trunk (FET) procedures. Fifty-seven patients with extensive thoracic aneurysmal disease were treated using elephant trunk (n = 36) or FET (n = 21) procedures. Patients with aortic dissection, descending thoracic aorta (DTA) diameter less than 40 mm, and thoracoabdominal aneurysms were excluded from the analysis, as were those who did not undergo antegrade selective cerebral perfusion during circulatory arrest. Short-term and mid-term outcomes were compared according to elephant trunk/FET surgical management. Preoperative and intraoperative variables were similar in the two groups, except for a higher incidence of female sex, coronary artery disease and associated procedures in elephant trunk patients. Hospital mortality (elephant trunk: 13.9% versus FET: 4.8%; P = 0.2), permanent neurologic dysfunction (elephant trunk: 5.7% versus FET: 9.5%; P = 0.4) and paraplegia (elephant trunk: 2.9% versus FET: 4.8%; P = 0.6) rates were similar in the two groups. Follow-up was 100% complete. In the elephant trunk group, 68.4% of patients did not undergo a second-stage procedure during follow-up for a variety of reasons. Of these patients, the DTA diameter was greater than 51 mm in 72.2% and two (6.7%) died due to aortic rupture while awaiting stage-two intervention. Endovascular second-stage procedures were successfully performed in all FET patients with residual DTA aneurysmal disease (n = 3), whereas nine of 11 elephant trunk patients who returned for second-stage procedures required conventional surgical replacement through a lateral thoracotomy. Kaplan-Meier estimate of 4-year survival was 75.8 ± 7.6 and 72.8 ± 10.6 in elephant trunk and FET patients, respectively (log-rank P = 0.8). In patients with extensive aneurysmal disease of thoracic aorta, elephant trunk and FET procedures

The purpose of this study was to review magnetic resonance imaging (MRI) scans of post-traumatic syringomyelia and to assess the outcome of surgical treatment. The subjects were 16 patients (13 men and 3 women) whose ages ranged from 22 to 69 years, with a mean of 42 years. Nine patients had delayed neurologic symptoms 2 years and 2 months through 32 years after spinal injuries. The site of initial spinal cord injury was the lower cervical region in 4 patients, the thoracic region in 8, and the upper lumbar region in 4. In all patients, post-traumatic syringomyelia was easy to diagnose on MRI. MRI showed the syrinx extending superiorly and/or inferiorly from the area of old trauma, sometimes extending to the medulla oblongata. In the cervical cord and the upper thoracic cord, the syrinx was unilaterally or bilaterally situated in the postero-lateral portion. Below the middle thoracic cord, the syrinx was centrally located. Surgery was performed in 6 patients. At an average follow up of 2 years and 9 months, both pain and numbness were relieved in all patients (100%) and neurologic symptoms improved in 5 patients (83%). Post-traumatic syringomyelia should be considered in all patients having delayed onset or aggravation of neurologic symptoms after spinal injury. MRI appears promising for the early diagnosis of post-traumatic syringomyelia that can be treated favorably by surgical procedures. (N.K.).

During thoracoscopic oesophageal surgery, we observed not previously described fascia-like structures. Description of similar structures in rectal cancer surgery was of paramount importance in improving the quality of resection. Therefore, we aimed to describe a new comprehensive concept of the surgical anatomy of the thoracic oesophagus with definition of the meso-oesophagus. We retrospectively evaluated 35 consecutive unedited videos of thoracoscopic oesophageal resections for cancer, to determine the surgical anatomy of the oesophageal fascia's vessels and lymphatic drainage. The resulting concept was validated in a prospective study, including 20 patients at three different centres. Additional confirmation was sought by a histologic study of a cadaver's thorax. A thin layer of connective tissue around the infracarinal oesophagus, involving the lymph nodes at the level of the carina, was observed during thoracoscopic esophagectomy in 32 of the 35 patients included in the retrospective study and in 19 of the 20 patients included in the prospective study. A thick fascia-like structure from the upper thoracic aperture to the lower thoracic aperture was visualized in all patients. This fascia is encountered between the descending aorta and left aspect of the infracarinal oesophagus. Above the carina it expands on both sides of the oesophagus to lateral mediastinal structures. This fascia contains oesophageal vessels, lymph vessels and nodes and nerves. The histologic study confirmed these findings. Here we described the concept of the "meso-oesophagus". Applying the description of the meso-oesophagus will create a better understanding of the oesophageal anatomy, leading to more adequate and reproducible surgery.

Full Text Available Previously described surgical treatment for ostial coronary artery stenosis relied on either venous or arterial bypasses or ostial patch angioplasty. These surgical procedures are performed with bovine pericardium, saphenous vein or internal thoracic artery. We describe a technique of right coronary artery re-implantation into the aorta. The procedure was performed in four patients with right coronary artery ostial stenosis along with other left coronary artery lesions.

2016-08-01

Lumbo-costo-vertebral syndrome (LCVS) is a rare disorder in children that is characterized by hemivertebrae, congenital absence of ribs, meningocele, and hypoplasia of the truncal and abdominal wall presenting as a congenital lumbar hernia. An otherwise healthy 12-month-old girl was referred to the authors' hospital with soft swelling on her left middle back; scoliosis had been present since birth. Imaging revealed a thoracic meningocele, ectopia of the spleen suggesting lumbar hernia, multiple anomalies of the thoracic vertebral columns, and defects of the ribs; thus, LCVS was diagnosed. Surgical observation revealed that the meningocele was firmly anchored to part of the diaphragm, which created stretching tension in the meningocele continuously with exhalation. Once detached, the meningocele shrank spontaneously and never developed again after cauterization. In this case, continuous or pulsatile pressure in the presence of a vertebral defect was thus considered to be an important factor for formation of the thoracic meningocele.

Cord Compression due to Extramedullary Hematopoiesis in an Adolescent with Known Beta Thalassemia Major

Full Text Available We describe a 16 year-old male with ß thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH. After treatment with steroids, radiotherapy and monitored blood transfusions, the patient demonstrated significant improvement of his paraspinal lesions and near complete resolution of his neurological symptoms. While EMH causing cord compression in adolescents is rare in the current era of bone marrow transplantation or chronic transfusions, it should be considered when thalassemia major patients present with neurological deficits. The well defined imaging features of EMH can play a central role in its diagnosis and management, especially because surgical and / or radiotherapeutic intervention are often considered in cases of failed medical treatment.

To identify core thoracic surgery procedures that require increased emphasis during thoracic surgery residency for residents to achieve operative independence and to compare the perspectives of residents and program directors in this regard. A modified Delphi process was used to create a survey that was distributed electronically to all Canadian thoracic surgery residents (12) and program directors (8) addressing the residents' ability to perform 19 core thoracic surgery procedures independently after the completion of residency. Residents were also questioned about the adequacy of their operative exposure to these 19 procedures during their residency training. A descriptive summary including calculations of frequencies and proportions was conducted. The perceptions of the 2 groups were then compared using the Fisher exact test employing a Bonferroni correction. The relationship between residents' operative exposure and their perceived operative ability was explored in the same fashion. The response rate was 100% for residents and program directors. No statistical differences were found between residents' and program directors' perceptions of residents' ability to perform the 19 core procedures independently. Both groups identified lung transplantation, first rib resection, and extrapleural pneumonectomy as procedures for which residents were not adequately prepared to perform independently. Residents' subjective ratings of operative exposure were in good agreement with their reported operative ability for 13 of 19 procedures. This study provides new insight into the perceptions of thoracic surgery residents and their program directors regarding operative ability. This study points to good agreement between residents and program directors regarding residents' surgical capabilities. This study provides information regarding potential weaknesses in thoracic surgery training, which may warrant an examination of the curricula of existing programs as well as a

Surgical resection represents one of the essential cornerstones in multimodal treatment of malignant pleural mesothelioma. In cases of tumor infiltration of the lung, lung-scarifying procedures such as lobectomies or pneumonectomies might be necessary to achieve macroscopic complete resection. However, this increases the morbidity of the patients because it leads to possible delay of the planned chemotherapy or radiotherapy. Innovative surgical techniques are therefore required to enable salvage of the lung parenchyma and optimization of surgical treatment. Here we report our first experience with a diode-pumped neodymium-doped yttrium aluminium garnet laser for parenchyma-sparing lung resection during surgery for malignant pleural mesothelioma.

Thymectomy may be part of the therapeutic strategy in patients with myasthenia gravis (MG) without thymoma. Median sternotomy is still considered as the gold standard, but during the last 15 years, several groups have demonstrated the non-inferiority of cervicotomy with upper sternotomy and minimally invasive techniques. To date, there is no consensus on surgical procedure choice. The aim of our study was to compare the morbidity and mortality of three techniques [cervicotomy with upper sternotomy versus sternotomy versus video-assisted thoracic surgery (VATS)/robotic-assisted thoracic surgery (RATS)] from the national database EPITHOR and to analyse French epidemiology. From the national thoracic surgery database EPITHOR, we have extracted all the details regarding thymectomies performed for non-thymomatous MG. We have divided thymectomy into three groups: A-sternotomy; B-cervicotomy with upper sternotomy; C-VATS/RATS. We investigated the postoperative morbidity and mortality without analysis of the long-term evolution of the disease not available on EPITHOR. From 2005 to 2013, 278 patients were included: 131 (47%) in Group A, 31 (11%) in Group B and 116 (42%) in Group C. The sex ratio F/M was 2.3. The mean age was, respectively, 42 ± 17, 42 ± 16, 35 ± 14 years old (P < 0.01). The number of patients without comorbidities was 63 (48%), 25 (81%) and 78 (65%), respectively (P < 0.01). The operative time was 94 ± 37, 79 ± 42 and 112 ± 59 min, respectively (P < 0.01). The number of patients who presented at least one postoperative complication was 12 (14%), 0 and 3 (9%) (P= 0.03), respectively. The postoperative lengths of stay were 7.7 ± 4.5, 5 ± 1.7 and 4.5 ± 2 days, respectively (P < 0.01). There was no death. In our study, we were unable to prove the superiority of minimally invasive techniques due to the important differences between the groups. However, this study shows us major changes in French surgical procedures during the last decade with an

To describe the clinical findings, diagnosis, and treatment of an incomplete cleft of the 5th-8th sternebra and a cranioventral abdominal wall hernia in a 2 month old Ragdoll kitten and to evaluate the short- and long-term outcome. Clinical report. Ragdoll cat (n = 1), 2 months old. Sternal cleft was confirmed by thoracic radiographs. Computed tomography (CT) was used to plan an optimal surgical approach. A ventral median incision was made, starting at the 3rd sternebra and extended into the abdomen. Ostectomy of the proximal part of the 5th left sternebra was performed. Lateral periosteal flaps were created, unfolded, and absorbable monofilament sutures preplaced to facilitate closure and the repair was reinforced by 2 peristernal sutures. A bone graft was applied, and the free margin of the omentum was sutured to the cranial aspect of the wound. No major complications occurred. At 3 weeks, CT scan confirmed approximation of the hemisternebrae and at 10 months, complete fusion of the hemisternebrae had not occurred, but a strong connection of the sternal bars was present. Sternal cleft is a rare congenital abnormality that can be corrected surgically with favorable outcome. © Copyright 2014 by The American College of Veterinary Surgeons.

Objective: To compare the dose distribution between three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT) in treating esophageal carcinoma (middle thoracic section and under thoracic section) and to select reasonable treatment methods for esophagus cancer. Methods: Ten cases with cancer of the middle thoracic section and under thoracic section esophagus were chosen for a retrospective treatment-planning study. 3DCRT and IMRT plans were created for each patient: Some critical indicators were evolved in evaluating the treatment plans of IMRT (5B and 7B) and 3DCRT (3B), such as, PTV coverage and dose-volumes to irradiated normal structures. Evaluation indicators: prescription of 50 Gy. total lung volume (V5, V10, V20), mean lung dose (MLD), spinal cord (Dmax), heart (V40) and conformality index (CI). Each plan was evaluated with respect to dose distribution,dose-volume histograms (DVHs), and additional dosimetric endpoints described below. Results: There is no significance of CRT and IMRT technique in protection of total lung volume,mean lung dose, spinal cord (Dmax), target, CI and heart. Conclusion: As To radiotherapy of esophagus cancer of the middle thoracic section and under thoracic section, IMRT has no advantage compared with 3DCRT, the selection of plan should be adapted to the situations of every patient.

Full Text Available Overestimation of the efficacy of conservative treatment of spine injuries children often leads to unsatisfactory long-term results. The effective correction of post-traumatic spinal column deformities occurs in patients who undergo the operation in the early post-traumatic period. While choosing treatment strategies for children, higher reparative opportunities, which provide early fracture consolidation, including those in faulty positions, should be considered. This study presents a case of surgical treatment for uncomplicated injury of the thoracic and lumbar spine, with long-term compression fragmental fracture of the L1 vertebra body in a 12-year-old child. Due to the long-standing character of the injury right thoraco-frenotomy was conducted with partial L1 vertebral body and resection of the adjacent discs, deformity correction of the thoracic and lumbar spine with a transpedicular system, and ventral spondylodesis with an autograft. This extensive intervention was justified by the peculiarities in the vertebral body damage and the post-traumatic segmental kyphotic deformity that resulted from delayed medical treatment. An anterior approach was chosen to achieve immobilization at the site of the damage before correction using the transpedicular system. Surgical correction of long-term spinal injuries in children, with the use of a combined approach, is usually laborious and traumatic. The prevention of rigid post-traumatic spine deformities with the help of timely diagnostics and appropriate treatment, including surgery, should be a priority to prevent such cases.

To analyze the initial thoracic involvement by CT in a consecutive series of patients with lymphoma. A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD) and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs

Objective: To analyze intrathoracic or extrathoracic recurrence pattern after surgical resection of thoracic esophageal squamous cell carcinoma (TESCC) and its help for further modify and improvement on the target of postoperative radiation therapy. Methods: One hundred and ninety-five patients who had undergone resection of TESCC at the Cancer Hospital, Chinese Academy of Medical Sciences enrolled from April 1999 to July 2007. Sites of failure on different primary location of esophageal cancer were documented. Results: Patients with upper or middle thoracic esophageal cancer had higher proportion of intrathoracic recurrence. Patients with lower thoracic esophageal cancer had more intrathoracic recurrence and abdominal lymph node metastatic recurrence. Histological lymph node status has nothing to do with intrathoracic recurrence, supraclavicular lymph node (SLN) metastasis or distant metastasis (χ 2 =1.58, 0.06, 0.04, P =0.134, 0.467, 0.489, respectively), whereas the chance of abdominal lymph node metastases in N positive patients was significantly higher than that in N 0 patients (28.7%: 10.6%, χ 2 =9.94, P =0.001), and so did in middle thoracic esophageal cancer (20.0%: 5.6%, χ 2 =5.67, P =0.015). Anatomic recurrence rate of patients with proximal resection margin no more than 3 cm was significantly higher compared to those more than 3 cm (25.0%: 11.3%, χ 2 =5.65, P=0.019). Conclusions: Mediastinum is the most common recurrence site.According to recurrence site, the following radiation targets are recommended: when tumor was located at the upper or middle thoracic esophagus with negative N status, the mediastinum, the tumor bed and the supraclavicular region should be included as postoperative RT target; when tumor was located at the middle thoracic esophagus with positive N or located at the lower thoracic esophagus, the abdominal lymph node should be added.If the proximal resection margin was no more than 3 cm, the anastomotic-stoma should be included

Use of surgery for the treatment of infective endocarditis (IE) as related to surgical indications and operative risk for mortality has not been well defined. The International Collaboration on Endocarditis-PLUS (ICE-PLUS) is a prospective cohort of consecutively enrolled patients with definite IE from 29 centers in 16 countries. We included patients from ICE-PLUS with definite left-sided, non-cardiac device-related IE who were enrolled between September 1, 2008, and December 31, 2012. A total of 1296 patients with left-sided IE were included. Surgical treatment was performed in 57% of the overall cohort and in 76% of patients with a surgical indication. Reasons for nonsurgical treatment included poor prognosis (33.7%), hemodynamic instability (19.8%), death before surgery (23.3%), stroke (22.7%), and sepsis (21%). Among patients with a surgical indication, surgical treatment was independently associated with the presence of severe aortic regurgitation, abscess, embolization before surgical treatment, and transfer from an outside hospital. Variables associated with nonsurgical treatment were a history of moderate/severe liver disease, stroke before surgical decision, and Staphyloccus aureus etiology. The integration of surgical indication, Society of Thoracic Surgeons IE score, and use of surgery was associated with 6-month survival in IE. Surgical decision making in IE is largely consistent with established guidelines, although nearly one quarter of patients with surgical indications do not undergo surgery. Operative risk assessment by Society of Thoracic Surgeons IE score provides prognostic information for survival beyond the operative period. S aureus IE was significantly associated with nonsurgical management. © 2014 American Heart Association, Inc.

Although direct vertebral rotation (DVR) is now used worldwide for the surgical treatment of adolescent idiopathic scoliosis (AIS), the benefit of DVR in reducing vertebral body rotation in these patients has not been determined. We investigated a possible additive effect of DVR on further reduction of vertebral body rotation in the axial plane following intraoperative rod rotation or differential rod contouring in patients undergoing surgical treatment for AIS. The study was a prospective computed tomography (CT) image analysis. We analyzed the results of the two intraoperative procedures in 30 consecutive patients undergoing surgery for AIS (Lenke type I or II: 15; Lenke type V: 15). The angle of reduction of vertebral body rotation taken by intraoperative CT scan was measured and analyzed. Pre- and postoperative responses to the Scoliosis Research Society 22 Questionnaire (SRS-22) were also analyzed. To analyze the reduction of vertebral body rotation with rod rotation or DVR, intraoperative cone-beam CT scans of the three apical vertebrae of the major curve of the scoliosis (90 vertebrae) were taken pre-rod rotation (baseline), post-rod rotation with differential rod contouring, and post-DVR in all patients. The angle of vertebral body rotation in these apical vertebrae was measured and analyzed for statistical significance. Additionally, differences between thoracic curve scoliosis (Lenke type I or II; 45 vertebrae) and thoracolumbar or lumbar curve scoliosis (Lenke type V; 45 vertebrae) were analyzed. Pre- and postoperative SRS-22 scores were evaluated in all patients. The mean (90 vertebrae) vertebral body rotation angles at baseline, post-rod rotation or differential rod contouring, and post-rod rotation or differential rod contouring or post-DVR were 17.3°, 11.1°, and 6.9°, respectively. The mean reduction in vertebral body rotation with the rod rotation technique was 6.8° for thoracic curves and 5.7° for thoracolumbar or lumbar curves (pself

Primary neuroendocrine carcinoma of thymus (pNECT) is a rare thymic neoplasm. Some pNECTs could produce an adrenocorticotropic hormone and cause Cushing syndrome (CS). The aim os this study is to discuss the diagnostic technique and surgical management of pNECT-caused CS and analyze prognosis factors to improve the clinical experience of the disease. The outcome of surgery and follow-up of 14 cases (eight males and six females) of pNECT-caused CS were retrospectively analyzed from November 1987 to June 2013. The median age of the patients was 29, and the median duration of the disease was four months (1 month-44 months). All cases exhibited clinical evidence for the diagnosis of CS, and thoracic computed tomography (CT) was used to detect thymic tumors. Surgical treatment significantly decreased the concentration of both serum cortisol and adrenocorticotropic hormone (Pdisease with aggressive characteristics and unclear prognosis. Early diagnosis and therapy is a challenge for clinicians. Thoracic CT is important for disease location and preoperative evaluation and should be routinely applied to all CS patients to allow early surgery and improved prognosis.

Twenty-one surgical cases out of 31 thoracic were discussed in comparison with computed tomography (CT), conventional chest x-ray film and findings on operation. CT was found useful in several respects. Azygo-esophageal recess (AER), which is normally seen between the vertebra and the carina, disappeared in the cases with enlarged lymph nodes around the carina. But AER was kept in the same fashion as normal in all cases free from those nodes enlargement. A low density line between tumor shadow and the mediastinum was good information to know preoperatively whether it was resectable or not. There were no resected cases of which CT films failed to show the border of the tumor shadow. Though CT is often used to evaluate mediastinal tumor, because of its horizontal cross picture, it is seldom diagnostic. Enlarged thoracic aorta and a minimum amount of calcium on its wall, and fat tissue in the retrosternal space which conventional x-ray films failed to reveal in both cases were definitive signs of aneurysm of thoracic aorta and foramen of Morgagni hernia respectively. CT is also able to demonstrate a small pulmonary nodules in the fields in much more early stage than conventional x-ray film is, which must be good adjunct to detect lung cancer. (author)

Full Text Available Objective: The objective of the study was to compare the outcomes of the incidence of nausea/vomiting and other complications along with the time taken for discharged in patients undergoing Thoracic Epidural Analgesia (TEA and General Anaesthesia (GA for breast oncological surgeries. Background: GA with or without TEA or other postoperative pain-relieving strategies remains the traditional anesthetic technique used for breast oncological procedures. We initiated the use of high segmental TEA for patients undergoing these procedures in our hospital. Methods: Eighty patients undergoing breast oncological procedures performed by one surgical team were randomly allocated into two groups receiving TEA and GA. The Chi-square test and Fisher's exact test were used for categorical parameters, paired t-test and Student's t-test was used for continuous measurements. Results: In comparison with GA, TEA was associated with lesser incidence of complications of nausea/vomiting. In lumpectomy with axillary node dissection, 1 out of 18 patients (5.55% in the TEA group had nausea/vomiting, while 11 out of 19 (57.8% of the GA group had similar symptoms (P < 0.001. The discharge rate for the thoracic epidural group was 12 out of 18 by day 3 (66.6% while all patients in the GA group required more than 3 days of hospitalization (P < 0.001. Conclusion: Thoracic epidural anesthesia is a safe technique and its use in breast oncological procedures could improve patients' recovery and facilitate their early discharge to home.

Full Text Available Esophageal diverticula in the pediatric population are rare. The etiologies and presentations can vary widely which can make it difficult to diagnose without imaging or direct visualization. We are reporting a case of a 14-year-old male with history of asthma, anorexia, weight loss, and chest discomfort. CXR findings of mediastinal widening prompted a more extensive evaluation. He was found to have two esophageal diverticula, phlegmonous changes, and osteomyelitis of the T5 and T6 vertebra. He was initially treated with IV antibiotic therapy, bypassing the affected area with nasogastric enteric tube feedings, and a cervical thoracic orthosis brace for spine stability. He regained his lost weight and became asymptomatic, returning to a regular diet. The family has declined to pursue surgical intervention at present.

A cadaveric laboratory study. The aim of this study was to assess the feasibility and accuracy of thoracic pedicle screw placement using augmented reality surgical navigation (ARSN). Recent advances in spinal navigation have shown improved accuracy in lumbosacral pedicle screw placement but limited benefits in the thoracic spine. 3D intraoperative imaging and instrument navigation may allow improved accuracy in pedicle screw placement, without the use of x-ray fluoroscopy, and thus opens the route to image-guided minimally invasive therapy in the thoracic spine. ARSN encompasses a surgical table, a motorized flat detector C-arm with intraoperative 2D/3D capabilities, integrated optical cameras for augmented reality navigation, and noninvasive patient motion tracking. Two neurosurgeons placed 94 pedicle screws in the thoracic spine of four cadavers using ARSN on one side of the spine (47 screws) and free-hand technique on the contralateral side. X-ray fluoroscopy was not used for either technique. Four independent reviewers assessed the postoperative scans, using the Gertzbein grading. Morphometric measurements of the pedicles axial and sagittal widths and angles, as well as the vertebrae axial and sagittal rotations were performed to identify risk factors for breaches. ARSN was feasible and superior to free-hand technique with respect to overall accuracy (85% vs. 64%, P dimensions, except for vertebral body axial rotation, were risk factors for larger breaches when performed with the free-hand method. ARSN without fluoroscopy was feasible and demonstrated higher accuracy than free-hand technique for thoracic pedicle screw placement. N/A.

A mycotic aneurysm of the thoracic aorta is a rare diagnosis with high mortality. We present two cases of endovascular reconstruction of mycotic descending thoracic aorta. Specific or nonspecific bacterial or other infectious agent in serial samples of blood, urine, cerebrospinal fluid, and pleural puncture was not detected in the first case, but we found in sputum sample Mycobacterium tuberculosis in the second patient. We empirically began by administering broad-spectrum intravenous antibiotics in the first case, with preoperative antibiotic prophylaxis and antituberculotic drugs therapy in the second case, and continued with the same medication for 4 months after endovascular repair. Control computed tomographic scans 6 months after reconstruction showed no endoleak in both patients. Repair of mycotic descending thoracic aortic aneurysms by endoluminal stent graft is reasonable alternative to open surgical intervention. A broad-spectrum antibiotic therapy has a high significance in the treatment of patients with mycotic aneurysm. Georg Thieme Verlag KG Stuttgart · New York.

Integrated 6-year cardiothoracic surgical residency programs have recently been implemented in the United States. We report the results of the first published nationwide survey assessing the motivations, satisfaction, and ambitions of integrated 6-year residents. A 63-question web-based survey was distributed to 83 residents enrolled in 21 Accreditation Council for Graduate Medical Education-accredited integrated 6-year programs in November 2013. There was an outstanding 69% response rate. The median age of integrated 6-year residents was 29 years with women comprising 24%. A clear majority had faculty mentorship (95%) and significant clinical exposure in medical school. Focused (100%) and abbreviated (74%) training curricula were identified as the top advantages of integrated 6-year programs; the format itself was a significant factor (46%) in career choice. Most integrated 6-year residents (95%) were satisfied with their program; 80.7% were satisfied with their operative experience thus far. Career plans skewed toward adult cardiac surgery (67%), followed by pediatric cardiac (24%) and general thoracic (9%) surgery; 49% were not particularly concerned about future employment, with 65% foreseeing an increase in opportunities. Specialized training (eg, aortic, heart failure, minimally invasive, congenital) was anticipated by 77%. Most integrated 6-year residents envision an academic career (94.7%). This survey takes an important snapshot of the nascent integrated 6-year format. Mentorship and intense clinical exposure are critical in attracting applicants. Purported advantages of the format are holding true among integrated 6-year residents, with the majority satisfied with their programs. These early data indicate that this format holds significant promise in attracting and retaining highly qualified trainees to academic cardiothoracic surgery.

2007-01-01

Bone metastases at the thoracic and lumbar segment of the spine are usually presented with painful sensation and medullar compression. The treatment is based on the clinical and neurological conditions of the patient and the degree of tumor invasion. In the present study, 32 patients with spinal metastasis of thoracic and lumbar segment were prospectively analyzed. These patients were treated by decompression and internal stabilization followed by radiotherapy or irradiation with external immobilization. The election of the groups was in accordance with the tumor radiotherapy sensitivity, clinical conditions, spinal stability, medullar or nerve compression and patient's decision. The Frankel scale and pain visual test were applied at the moment of diagnosis and after 1 and 6 months. The surgical group had better results with preserving the ambulation longer and significant reduction of pain.(author)

A ferromagnetic surgical system (FMwand®) is a new type of dissection device expected to reduce the risk of adjacent tissue damage. We reviewed 426 congenital cardiac operations with cardiopulmonary bypass through redo sternotomy to assess if this device prevented phrenic nerve injury. The ferromagnetic surgical system was used in 203 operations (47.7%) with regular electrocautery and scissors. The preoperative and operative details were similar between the operations with or without the ferromagnetic surgical system. The incidence of phrenic nerve injury was significantly lower with the ferromagnetic surgical system (0% vs 2.7%, P = 0.031). A logistic regression model showed that the use of the ferromagnetic surgical system was significantly associated with reduced odds of phrenic nerve injury (P < 0.001). © The Author 2017.

Scaglione, M.; Pinto, A.; Pinto, F.; Romano, L.; Ragozzino, A.; Grassi, R.

2001-01-01

The purpose of this retrospective study was to determine the value of contrast-enhanced helical CT for detecting and managing acute thoracic aortic injury (ATAI). Between June 1995 and February 2000, 1419 consecutive chest CT examinations were performed in the setting of major blunt trauma. The following CT findings were considered indicative of ATAI: intimal flap; pseudoaneurysm; contour irregularity; lumen abnormality; and extravasation of contrast material. On the basis of these direct findings no further diagnostic investigations were performed. Isolated mediastinal hematoma on CT scans was considered an indirect sign of ATAI: In these cases, thoracic aortography was performed even if CT indicated normal aorta. Seventy-seven patients had abnormal CT scans: Among the 23 patients with direct CT signs, acute thoracic aortic injuries was confirmed at thoracotomy in 21. Two false-positive cases were observed. The 54 remaining patients had isolated mediastinal hematoma without aortic injuries at CT and corresponding negative angiograms. The 1342 patients with negative CT scans were included in the 8-month follow-up program and did not show any adverse sequela based on clinical and radiographic criteria. Contrast-enhanced helical CT has a critical role in the exclusion of thoracic aortic injuries in patient with major blunt chest trauma and prevents unnecessary thoracic aortography. Direct CT signs of ATAI do not require further diagnostic investigations to confirm the diagnosis: Isolated aortic bands or contour vessel abnormalities should be first considered as possible artifacts or related to non-traumatic etiologies especially when mediastinal hematoma is absent. In cases of isolated mediastinal hematoma other possible sources of bleeding should be considered before directing patients to thoracic aortography. (orig.)

Thoracic outlet syndrome is caused by compression of the neurovascular bundle as it passes from the upper thorax to the axilla. The neurovascular bundle can be compressed by bony structures such as the first rib, cervical ribs or bone tubercles, or from soft-tissue abnormalities like a fibrous band, muscle hypertrophy or space-occupying lesion. Thoracic outlet syndrome commonly affects young adults but can be seen in the pediatric age group, especially in older children. Diagnosis is based on a holistic approach encompassing clinical features, physical examination findings including those triggered by various maneuvers, electromyography, nerve conduction studies and imaging. Imaging is performed to confirm the diagnosis, exclude mimics and classify thoracic outlet syndrome into neurogenic, arterial, venous or mixed causes. MRI and MR angiography are useful in this process. A complete MRI examination for suspected thoracic outlet syndrome should include the assessment of anatomy and any abnormalities using routine sequences, vessel assessment with the arms in adduction by MR angiography and assessment of dynamic compression of vessels with abduction of the arms. The purpose of this paper is to describe the anatomy of the thoracic outlet, causes of thoracic outlet syndrome, the MR imaging techniques used in its diagnosis and the principles of image interpretation.

Aorto-esophageal fistula (AEF) is a rare and lethal entity, and the difficulty of making diagnosis of AEF is well-known. As promising results in the short-term effectiveness of thoracic endovascular aortic repair (TEVAR) promote its usage, the occurrence of AEF after TEVAR (post-TEVAR AEF) increases as one of the major complications. Therefore, we provide a review concerning the management strategy of post-TEVAR AEF. Although its representative symptom was reported as the triad of mid-thoracic pain and sentinel hematemesis followed by massive hematemesis, the symptom-free interval between sentinel hemorrhage and massive exsanguination is unpredictable. However, the physiological condition represents a surgical contraindication. Accordingly, early diagnosis is important, but either CT or esophago-gastro-duodenoscopy rarely depicts a typical image. The formation of post-TEVAR AEF might be associated with the infection of micro-organisms, which is uncontrollable with anti-biotic administration. The current first-line strategy is combination therapy as follows, (1) to control bleeding by TEVAR in the urgent phase, and (2) radical debridement and aortic/esophageal re-construction in the semi-urgent phase. In view of the high mortality and morbidity rate, it is proposed that the choice in treatment strategies might be affected by patient`s condition, size of the wall defects and the etiology of AEF. Practically, we should keep in mind the importance of making an early diagnosis and, once a suspicious symptom has occurred in a patient with a history of TEVAR, the existence of post-TEVAR AEF should be suspected. A prospective registry together with more developed technologies will be needed to establish a future strategy.

Full Text Available Abstract Background The aim of this prospective study is to evaluate the role in the onset of surgical site infections of bilateral internal thoracic arteries harvesting in patients with decompensated preoperative glycemia. Methods 81 consecutive patients with uncontrolled diabetes mellitus underwent elective CABG harvesting single or double internal thoracic arteries. Single left ITA was harvested in 41 patients (Group 1, 50.6%, BITAs were harvested in 40 (Group 2, 49.4%. The major clinical end points analyzed in this study were infection rate, type of infection, duration of infection, infection relapse rate and total hospital length of stay. Results Five patients developed sternal SSI in the perioperative period, 2 in group 1 and 3 in group 2 without significant difference. All sternal SSIs were superficial with no sternal dehiscence. The development of infection from the time of surgery took 18.5 ± 2.1 and 7.3 ± 3.0 days for Groups 1 and 2 respectively. The infections were treated with wound irrigation and debridement, and with VAC therapy as well as with antibiotics. The VAC system was removed after a mean of 12.8 ± 5.1 days, when sterilization was achieved. The overall survival estimate at 1 year was 98.7%. Only BMI was a significant predictor of SSI using multivariate stepwise logistic regression analysis (Odds Ratio: 1.34; 95%Conficdence Interval: 1.02–1.83; p value: 0.04. In the model, the use of BITA was not an independent predictor of SSI. Conclusion CABG with bilateral pedicled ITAs grafting could be performed safely even in diabetics with poor preoperative glycaemic control.

Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

Fracture of the first rib with ensuing callus formation is a rare cause of thoracic outlet syndrome. We report a case of a 17-year-old female volleyball player who presented with months of chronic arm pain. Radiographic imaging demonstrated nonunion fracture of the first rib. Physical therapy had been unsuccessful in relieving the pain, and surgical management was performed with resection of the first rib through a transaxillary approach with complete resolution of symptoms. Inflammation surrounding such fractures may destroy tissue planes, making dissection more technically difficult.

We retrospectively examined intraoperative blood transfusion patterns at US veteran's hospitals through description of national patterns of intraoperative blood transfusion by indication for transfusion in the elderly; assessment of temporal trends in the use of intraoperative blood transfusion; and relationship of institutional use of intraoperative blood transfusion to hospital 30-day risk-adjusted postoperative mortality rates.Limited data exist on the pattern of intraoperative blood transfusion by indication for transfusion at the hospital level, and the relationship between intraoperative transfusion rates and institutional surgical outcomes.Using the Department of Veterans Affairs Surgical Quality Improvement Program database, we assigned 424,015 major noncardiac operations among elderly patients (≥65 years) in 117 veteran's hospitals, from 1997 to 2009, into groups based on indication for intraoperative blood transfusion according to literature and clinical guidelines. We then examined institutional variations and temporal trends in surgical blood use based on these indications, and the relationship between these institutional patterns of transfusion and 30-day postoperative mortality.Intraoperative transfusion occurred in 38,056/424,015 operations (9.0%). Among the 64,390 operations with an indication for transfusion, there was wide variation (median: 49.9%, range: 8.7%-76.2%) in hospital transfusion rates, a yearly decline in transfusion rates (average 1.0%/y), and an inverse relationship between hospital intraoperative transfusion rates and hospital 30-day risk-adjusted mortality (adjusted mortality of 9.8 ± 2.8% vs 8.3 ± 2.1% for lowest and highest tertiles of hospital transfusion rates, respectively, P = 0.02). In contrast, for the 225,782 operations with no indication for transfusion, there was little variation in hospital transfusion rates (median 0.7%, range: 0%-3.4%), no meaningful temporal change in transfusion (average 0.0%/y), and

Aesthetic breast area improvements for gynecomastia and gender dysphoria patients who seek a more masculine appearance have increased recently. We present our clinical experience in breast masculinization and a classification for these patients. From July 2003 to May 2014, 68 patients seeking a more masculine thorax underwent surgery. They were divided into five groups depending on three factors: excess fatty tissue, breast tissue, and skin. A specific surgical treatment was assigned according to each group. The surgical treatments included thoracic liposuction, subcutaneous mastectomy, periareolar skin resection in one or two stages, and mastectomy with a nipple areola complex graft. The evaluation was performed 6 months after surgery to determine the degree of satisfaction and presence of complications. Surgery was performed on a total of 68 patients, 45 male and 22 female, with ages ranging from 18 to 49 years, and an average age of 33 years. Liposuction alone was performed on five patients; subcutaneous mastectomy was performed on eight patients; subcutaneous mastectomy combined with liposuction was performed on 27 patients; periareolar skin resection was performed on 11 patients; and mastectomy with NAC free grafts was performed on 16 patients. The surgical procedure satisfied 94% of the patients, with very few complications. All patients who wish to obtain a masculine breast shape should be treated with only one objective regardless patient's gender: to obtain a masculine thorax. We recommend a simple mammary gland classification for determining the best surgical treatment for these patients LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Advantages of thoracic paravertebral analgesia (TPA) include placement of the catheter closer to the surgical field; however, the catheter can become damaged during the operation. We experienced a case of intraoperative TPA catheter breakage that prompted us to perform an experiment to investigate possible causes. A 50-year-old male underwent a thoracoscopic lower lobectomy under general anesthesia with TPA via an intercostal approach. Following surgery, it was discovered that the catheter had become occluded, as well as cut and fused, so we reopened the incision and removed the residual catheter. From that experience, we performed an experiment to examine electrocautery-induced damage in normal (Portex™, Smith's Medical), radiopaque (Perifix SoftTip™, BBraun), and reinforced (Perifix FX™, BBraun) epidural catheters (n = 8 each). Chicken meat was penetrated by each catheter and then cut by electrocautery. In the normal group, breakage occurred in 8 and occlusion in 6 of the catheters, and in the radiopaque group breakage occurred in 8 and occlusion in 7. In contrast, breakage occurred in only 3 and occlusion in none in the reinforced group, with the 5 without breakage remaining connected only by the spring coil. Furthermore, in 7 of the reinforced catheters, electric arc-induced thermal damage was observed at the tip of the catheter. A TPA catheter for thoracic surgery should be inserted via the median approach, or it should be inserted after surgery to avoid catheter damage during surgery.

Full Text Available OBJECTIVE: To evaluate early and mid-term results in patients undergoing proximal thoracic aortic redo surgery. METHODS: We analyzed 60 patients (median age 60 years, median logistic EuroSCORE 40 who underwent proximal thoracic aortic redo surgery between January 2005 and April 2012. Outcome and risk factors were analyzed. RESULTS: In hospital mortality was 13%, perioperative neurologic injury was 7%. Fifty percent of patients underwent redo surgery in an urgent or emergency setting. In 65%, partial or total arch replacement with or without conventional or frozen elephant trunk extension was performed. The preoperative logistic EuroSCORE I confirmed to be a reliable predictor of adverse outcome- (ROC 0.786, 95%CI 0.64-0.93 as did the new EuroSCORE II model: ROC 0.882 95%CI 0.78-0.98. Extensive individual logistic EuroSCORE I levels more than 67 showed an OR of 7.01, 95%CI 1.43-34.27. A EuroSCORE II larger than 28 showed an OR of 4.44 (95%CI 1.4-14.06. Multivariate logistic regression analysis identified a critical preoperative state (OR 7.96, 95%CI 1.51-38.79 but not advanced age (OR 2.46, 95%CI 0.48-12.66 as the strongest independent predictor of in-hospital mortality. Median follow-up was 23 months (1-52 months. One year and five year actuarial survival rates were 83% and 69% respectively. Freedom from reoperation during follow-up was 100%. CONCLUSIONS: Despite a substantial early attrition rate in patients presenting with a critical preoperative state, proximal thoracic aortic redo surgery provides excellent early and mid-term results. Higher EuroSCORE I and II levels and a critical preoperative state but not advanced age are independent predictors of in-hospital mortality. As a consequence, age alone should no longer be regarded as a contraindication for surgical treatment in this particular group of patients.

In a report describing life ending fractures (255 horses) from the Livestock Disease Diagnostic Center, Kentucky (1993 and 1994), 32 foals had rib fractures. The purpose of our study was to examine the incidence of rib fractures in newborn foals on a Thoroughbred studfarm by physical and radiographic examination, to determine factors which may contribute to the problem and to document any clinical consequences. All foals (263) included were examined within 3 days of birth. The thoracic cage was palpated externally for abnormalities and all foals were placed in dorsal recumbency to evaluate thoracic cage symmetry. Radiographs were used to diagnose foals with thoraciccage asymmetry (TCA) and rib fracture (RF). A diagnosis of costochondral dislocation (CD) was made when no radiographic evidence of fracture was present but there was severe TCA, Fifty-five foals (20.1%) had TCA (9 RF), One to 5 ribs were fractured on 9 of 40 radiographic studies. No consequences of the thoracic trauma was detected clinically, radiographically or ultrasonographically in this group of foals or at a 2- and 4-week follow-up examination. The percentage of foals with a history of abnormal parturition was higher in the TCA foals (15%) compared to the normal foals (6.8%). There weremore primiparous dams in the TCA group than in the normal foal group. Fillies (56.6%) had a higher incidence of birth trauma than colts (43.4%), Thisstudy demonstrates that thoracic trauma is often present in newborn foals and may not always be of clinical significance. Dystocia foals and foals from primiparous mares should be considered high risk for thoracic trauma

In various surgical cases, effective tissue adhesives are required for both hemostasis (eg, intraoperative bleeding) and air sealing (eg, thoracic surgery). We have designed a chitosan molecule (Az-CH-LA) that can be photocrosslinked by ultraviolet (UV) light irradiation, thereby forming a hydrogel. The purpose of this work was to evaluate the effectiveness and safety of the photocrosslinkable chitosan hydrogel as an adhesive with surgical applications. The sealing ability of the chitosan hydrogel, determined as a bursting pressure, was assessed with removed thoracic aorta, trachea, and lung of farm pigs and in a rabbit model. The carotid artery and lung of rabbits were punctured with a needle, and the chitosan hydrogel was applied to, respectively, stop the bleeding and the air leakage. In vivo chitosan degradability and biologic responses were histologically assessed in animal models. The bursting pressure of chitosan hydrogel (30 mg/mL) and fibrin glue, respectively, was 225 +/- 25 mm Hg (mean +/- SD) and 80 +/- 20 mm Hg in the thoracic aorta; 77 +/- 29 mm Hg and 48 +/- 21 mm Hg in the trachea; and in the lung, 51 +/- 11 mm Hg (chitosan hydrogel), 62 +/- 4 mm Hg (fibrin glue, rubbing method), and 12 +/- 2 mm Hg (fibrin glue, layer method). The sealing ability of the chitosan hydrogel was stronger than that of fibrin glue. All rabbits with a carotid artery (n = 8) or lung (n = 8) that was punctured with a needle and then sealed with chitosan hydrogel survived the 1-month observation period without any bleeding or air leakage from the puncture sites. Histologic examinations demonstrated that 30 days after application, a fraction of the chitosan hydrogel was phagocytosed by macrophages, had partially degraded, and had induced the formation of fibrous tissues around the hydrogel. A newly developed photocrosslinkable chitosan has demonstrated strong sealing ability and a great potential for use as an adhesive in surgical operations.

The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

2007-03-01

Full Text Available Abstract Background Long thoracic nerve injury leading to scapular winging is common, often caused by closed trauma through compression, stretching, traction, direct extrinsic force, penetrating injury, or neuritides such as Parsonage-Turner syndrome. We undertook the largest series of long thoracic nerve decompression and neurolysis yet reported to demonstrate the usefulness of long thoracic nerve decompression. Methods Winging was bilateral in 3 of the 47 patients (26 male, 21 female, yielding a total of 50 procedures. The mean age of the patients was 33.4 years, ranging from 24–57. Causation included heavy weight-lifting (31 patients, repetitive throwing (5 patients, deep massage (2 patients, repetitive overhead movement (1 patient, direct trauma (1 patient, motor bike accident (1 patient, and idiopathic causes (9 patients. Decompression and microneurolysis of the long thoracic nerve were performed in the supraclavicular space. Follow-up (average of 25.7 months consisted of physical examination and phone conversations. The degree of winging was measured by the operating surgeon (RKN. Patients also answered questions covering 11 quality-of-life facets spanning four domains of the World Health Organization Quality of Life questionnaire. Results Thoracic nerve decompression and neurolysis improved scapular winging in 49 (98% of the 50 cases, producing "good" or "excellent" results in 46 cases (92%. At least some improvement occurred in 98% of cases that were less than 10 years old. Pain reduction through surgery was good or excellent in 43 (86% cases. Shoulder instability affected 21 patients preoperatively and persisted in 5 of these patients after surgery, even in the 5 patients with persistent instability who experienced some relief from the winging itself. Conclusion Surgical decompression and neurolysis of the long thoracic nerve significantly improve scapular winging in appropriate patients, for whom these techniques should be considered

To our knowledge, few studies have compared complications and surgical outcomes of adolescent idiopathic scoliosis (AIS) between junior attending surgeons and senior attending surgeons. To compare surgical strategies, complications, and outcomes of posterior corrective surgery for AIS between junior attending surgeons and senior attending surgeons. According to experience level of operation surgeons, the patients were assigned to 2 groups. Group A was the "junior surgeon" group. Group B was the "senior surgeon" group. The following parameters were compared between the 2 groups: age, sex, diagnosis, hospital of record, surgeon experience level, type of instrumentation, type of screws, estimated blood loss, duration of surgery, length of fusion, correction techniques, main curve correction, and thoracic kyphosis correction. A total of 132 patients with AIS were included in group A, whereas 207 were in group B. The translational technique was used more often in group A (P Senior surgeons used more monoaxial screws than junior surgeons (P senior group (P senior group had significant better correction rates of severe main curve (>70°) and thoracic kyphosis than the junior group (P Senior attending surgeons outperformed junior surgeons in blood loss control, thoracic kyphosis correction, and correction of severe curves.

This retrospective study was carried out to evaluate the indications for and outcomes of the hemiclamshell (HCS) approach (longitudinal partial sternotomy with antero-lateral thoracotomy) in patients undergoing mass resection in thoracic surgery. All patients (50) who underwent a HCS procedure in our department, between July 1996 and July 2005, were studied retrospectively, analyzing the indications, morbidity and outcome (pain, neurological or shoulder defects, mortality) at one month and one year. The main indications were apical tumours (38%), tumours of the cervicothoracic junction (46%) and chest wall (10%), and 'bulky' tumours (6%). One-month mortality was 6%. Two patients suffered from a chylothorax and one from phrenic paralysis. The postoperative analgesic requirements were similar to those after other thoracic surgery approaches. Twelve percent of patients suffered pain at one month and 6% at one year. Shoulder dysfunction was observed in 10% of patients at one month and 6% at one year. In conclusion, the HCS surgical approach was associated with an uncomplicated postoperative course. This anterior approach is suitable for apical tumours, tumours of the cervicothoracic junction and 'bulky' lung tumours, providing good access for control of the large vessels and radical mediastinal clearance.

Randomized clinical trial. To determine the effectiveness of seated thoracic manipulation versus targeted supine thoracic manipulation on cervical spine pain and flexion range of motion (ROM). There is evidence that thoracic spine manipulation is an effective treatment for patients with cervical spine pain. This evidence includes a variety of techniques to manipulate the thoracic spine. Although each of them is effective, no research has compared techniques to determine which produces the best outcomes. A total of 39 patients with cervical spine pain were randomly assigned to either a seated thoracic manipulation or targeted supine thoracic manipulation group. Pain and flexion ROM measures were taken before and after the intervention. Pain reduction (post-treatment-pre-treatment) was significantly greater in those patients receiving the targeted supine thoracic manipulation compared to the seated thoracic manipulation (Pmanipulation group. The results of this study indicate that a targeted supine thoracic manipulation may be more effective in reducing cervical spine pain and improving cervical flexion ROM than a seated thoracic manipulation. Future studies should include a variety of patients and physical therapists (PTs) to validate our findings.

Lung and cardiovascular monitoring applications of electrical impedance tomography (EIT) require localization of relevant functional structures or organs of interest within the reconstructed images. We describe an algorithm for automatic detection of heart and lung regions in a time series of EIT images. Using EIT reconstruction based on anatomical models, candidate regions are identified in the frequency domain and image-based classification techniques applied. The algorithm was validated on a set of simultaneously recorded EIT and CT data in pigs. In all cases, identified regions in EIT images corresponded to those manually segmented in the matched CT image. Results demonstrate the ability of EIT technology to reconstruct relevant impedance changes at their anatomical locations, provided that information about the thoracic boundary shape (and electrode positions) are used for reconstruction.

Type Ia endoleaks are not uncommon complications that occur after thoracic endovascular aortic repair (TEVAR). Because aortic arch vessels prevent extension of the landing zone, it is very difficult to manipulate a type Ia endoleak using an extension cuff or stent-graft, especially when the aortic arch is involved. Here, we retrospectively review our experience of surgical treatment of type Ia endoleak after TEVAR using a stented elephant trunk procedure. From July 2010 to August 2016, we treated 17 patients diagnosed with a type Ia endoleak following TEVAR using stented elephant trunk procedure. The mean age of our patients was 52 ± 8 years. The mean interval between TEVAR and the open surgical repair was 38 ± 43 months. All cases of type Ia endoleak (100%) were repaired successfully. There were no in-hospital deaths. One case required reintubation and continuous renal replacement therapy due to renal failure; this patient recovered smoothly before discharge. One other patient suffered a stroke and renal failure and did not fully recover following discharge, or follow-up. During follow-up, there were 3 deaths. Acceptable results were obtained using a stented elephant trunk procedure in patients with a type Ia endoleak after TEVAR. This technique allowed us to repair the proximal aortic arch lesions, surgically correct the type Ia endoleak, and promote false lumen thrombosis in the distal aorta. Implantation of a stented elephant trunk, with or without a concomitant aortic arch procedure, is an alternative approach for this type of lesion.

2008-01-01

Thoracic trauma secondary to motor vehicle crashes (MVC) continues to be a major cause of morbidity and mortality. Specific vehicle features may increase the risk of severe thoracic injury when striking the occupant. We sought to determine which vehicle contact points were associated with an increased risk of severe thoracic injury in MVC to focus subsequent design modifications necessary to reduce thoracic injury. The National Automotive Sampling System (NASS) databases from 1993 to 2001 and the Crash Injury Research and Engineering Network (CIREN) databases from 1996 to 2004 were analyzed separately using univariate and multivariate logistic regression stratified by restraint use and crash direction. The risk of driver thoracic injury, defined as an abbreviated injury scale (AIS) of score > or =3, was determined as it related to specific points of contact between the vehicle and the driver. The incidence of severe chest injury in NASS and CIREN were 5.5% and 33%, respectively. The steering wheel, door panel, armrest, and seat were identified as contact points associated with an increased risk of severe chest injury. The door panel and arm rest were consistently a frequent cause of severe injury in both the NASS and CIREN data. Several vehicle contact points, including the steering wheel, door panel, armrest and seat are associated with an increased risk of severe thoracic injury when striking the occupant. These elements need to be further investigated to determine which characteristics need to be manipulated in order to reduce thoracic trauma during a crash.

Radiographic evaluation of obesity-caused oppression of the thoracic cavity in beagles

Morooka, T.; Niiyama, M.; Kougo, A.; Soya, M.; Nunome, K.

2004-01-01

Thoracic radiographs of fifteen beagles with mild-to-moderate obesity revealed that oppression of the thoracic cavity increased with increasing degree of obesity. Oppression of the thoracic cavity was evaluated based on the length, depth, width and area of the thoracic cavity. To obtain thoracic radiographs at the terminal inspiration and expiration phases, thoracic fluororadiographs were recorded with a digital video camera. Bodyweight and the depth of the back fat layer at the seventh lumbar vertebra (DB, measured by ultrasonography) were used as indicators of the degree of obesity. The length of the thoracic cavity tended to become shorter and the depth and width of the thoracic cavity tended to increase as bodyweight increased and as DB increased. On the other hand, the area of the thoracic cavity was not clearly related to bodyweight or DB. These results suggest that oppression of the thoracic cavity due to the cranial shift of the diaphragm is compensated for by increases in the depth and width of the thoracic cavity in beagles with mild-to-moderate obesity

A benign fistula between the gastric tube and the airway resulting from esophagectomy is a rare complication, but it is a potentially life-threatening status. We present a 59-year-old man with thoracic empyema and lung abscess resulting from a benign gastric tube-to-pulmonary fistula caused by a penetration of the peptic ulcer in the gastric tube four years after an esophagectomy for esophageal cancer. After a thorough conservative management of infection and nutrition, the fistula was successfully repaired surgically with direct closure. The postoperative course was uneventful. Two years and nine months later, the patient retains satisfactory oral feeding status and is in good general condition.

VATS Lobectomy: Surgical Evolution from Conventional VATS to Uniportal Approach

Directory of Open Access Journals (Sweden)

Diego Gonzalez-Rivas

2012-01-01

Full Text Available There is no standardized technique for the VATS lobectomy, though most centres use 2 ports and add a utility incision. However, the procedure can be performed by eliminating the two small ports and using only the utility incision with similar outcomes. Since 2010, when the uniportal approach was introduced for major pulmonary resection, the technique has been spreading worldwide. The single-port technique provides a direct view to the target tissue. The conventional triple port triangulation creates a new optical plane with genesis of dihedral or torsional angle that is not favorable with standard two-dimension monitors. The parallel instrumentation achieved during single-port approach mimics inside the maneuvers performed during open surgery. Furthermore, it represents the less invasive approach possible, and avoiding the use of trocar, we minimize the compression of the intercostal nerve. Further development of new technologies like sealing devices for all vessels and fissure, robotic arms that open inside the thorax, and wireless cameras will facilitate the uniportal approach to become the standard surgical procedure for pulmonary resection in most thoracic departments.

Pellegrini, Joseph E; Toledo, Paloma; Soper, David E; Bradford, William C; Cruz, Deborah A; Levy, Barbara S; Lemieux, Lauren A

Surgical site infections are the most common complications of surgery in the United States. Of surgeries in women of reproductive age, hysterectomy is one of the most frequently performed, second only to cesarean birth. Therefore, prevention of surgical site infections in women undergoing gynecologic surgery is an ideal topic for a patient safety bundle. The primary purpose of this safety bundle is to provide recommendations that can be implemented into any surgical environment in an effort to reduce the incidence of surgical site infection. This bundle was developed by a multidisciplinary team convened by the Council on Patient Safety in Women's Health Care. The bundle is organized into four domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. In addition to recommendations for practice, each of the domains stresses communication and teamwork between all members of the surgical team. Although the bundle components are designed to be adaptable to work in a variety of clinical settings, standardization within institutions is encouraged.

Full Text Available Abstract Introduction A blunt thoracic trauma may cause arterial bleeding requiring operative treatment or endovascular embolization or endovascular aortic stenting. A novel damage control technique to stop such bleeding is presented. Case presentation We present the case of an 82-year-old Caucasian man who experienced rib fractures I-VII on the left side and bleeding from damaged intercostal arteries after a blunt thoracic trauma. Emergency thoracotomy was performed. Conclusions Effective hemostasis was achieved by using a rolled surgical swab and inserting it against the chest wall next to the aorta with sutures pulled through the intercostal muscles and then sutured to the back side of the patient. The patient died four days after the surgery due to a head injury sustained in the car crash.

Predicting outcome of rethoracotomy for suspected pericardial tamponade following cardio-thoracic surgery in the intensive care unit

Full Text Available Abstract Objectives Pericardial tamponade after cardiac surgery is difficult to diagnose, thereby rendering timing of rethoracotomy hard. We aimed at identifying factors predicting the outcome of surgery for suspected tamponade after cardio-thoracic surgery, in the intensive care unit (ICU. Methods Twenty-one consecutive patients undergoing rethoracotomy for suspected pericardial tamponade in the ICU, admitted after primary cardio-thoracic surgery, were identified for this retrospective study. We compared patients with or without a decrease in severe haemodynamic compromise after rethoracotomy, according to the cardiovascular component of the sequential organ failure assessment (SOFA score. Results A favourable haemodynamic response to rethoracotomy was observed in 11 (52% of patients and characterized by an increase in cardiac output, and less fluid and norepinephrine requirements. Prior to surgery, the absence of treatment by heparin, a minimum cardiac index 2 and a positive fluid balance (> 4,683 mL were predictive of a beneficial haemodynamic response. During surgery, the evacuation of clots and > 500 mL of pericardial fluid was associated with a beneficial haemodynamic response. Echocardiographic parameters were of limited help in predicting the postoperative course, even though 9 of 13 pericardial clots found at surgery were detected preoperatively. Conclusion Clots and fluids in the pericardial space causing regional tamponade and responding to surgical evacuation after primary cardio-thoracic surgery, are difficult to diagnose preoperatively, by clinical, haemodynamic and even echocardiographic evaluation in the ICU. Only absence of heparin treatment, a large positive fluid balance and low cardiac index predicted a favourable haemodynamic response to rethoracotomy. These data might help in deciding and timing of reinterventions after primary cardio-thoracic surgery.

2014-01-01

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can't tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than

Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare. We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.

Post thoracotomy chronic pain is a severe problem that affects the majority of patients and decreases the quality of life. The purpose of this study is to evaluate the long-term effects of thoracal epidural levobupivacaine and intravenous dexketoprofen analgesia formed pre-emptively on the wound site pain after major thoracotomy operations. This randomised, prospective and double-blind study was performed with 60 patients undergoing thoracic surgery. Patients were divided into three groups; Control Group (Group C), Pre-emptive Epidural Group (Group PE) and Pre-emptive Dexketoprofen + Epidural Group (Group PED). Patients in the Group C did not receive epidural analgesics and i.v. dexketoprofen before and during the operation. 10-15 ml 0.125% levobupivacaine was given to cases in Group PE pre-emptively through epidural catheter before the anesthesia induction. The cases in Group PED were given 10-15 ml 0.125% epidural levobupivacaine and 50 mg dexketoprofen with i.v. infusion pre-emptively. The VAS score was found to be lower in Group PED during postoperative 24 and 48 hours and before the discharge (P0.05). A statistically significant decrease was determined in the VAS score in Group PED during the sixth month, compared to the other groups (Pdexketoprofen and thoracal epidural analgesia reduce the chronic post-thoracotomy pain.

Pectoral Nerves Block (PECS) and Serratus Plane Block (SPB) have been used to treat persistent post-surgical pain after breast and thoracic surgery; however, they cannot block the internal mammary region, so a residual pain may occur in that region. Parasternal block (PSB) and Thoracic Transversus Plane Block (TTP) anaesthetize the anterior branches of T2-6 intercostal nerves thus they can provide analgesia to the internal mammary region. We describe a 60-year-old man suffering from right post-thoracotomy pain syndrome with residual pain located in the internal mammary region after a successful treatment with PECS and SPB. We performed a PSB and TTP and hydrodissection of fascial planes with triamcinolone and Ropivacaine. Pain disappeared and the result was maintained 3 months later. This report suggests that PSB and TTP with local anaesthetic and corticosteroid with hydrodissection of fascial planes might be useful to treat a post thoracotomy pain syndrome located in the internal mammary region. The use of Transversus Thoracic Plane and Parasternal Blocks and fascial planes hydrodissection as a novel therapeutic approach to treat a residual post thoracotomy pain syndrome even when already treated with Pectoral Nerves Block and Serratus Plane Block. © 2018 European Pain Federation - EFIC®.

Abstract Literature examining magnetic resonance imaging (MRI) in acute spinal cord injury (SCI) has focused on cervical SCI. Reproducible systems have been developed for MRI-based grading; however, it is unclear how they apply to thoracic SCI. Our hypothesis is that MRI measures will group as coherent multivariate principal component (PC) ensembles, and that distinct PCs and individual variables will show discriminant validity for predicting early impairment in thoracic SCI. We undertook a retrospective cohort study of 25 patients with acute thoracic SCI who underwent MRI on admission and had American Spinal Injury Association Impairment Scale (AIS) assessment at hospital discharge. Imaging variables of axial grade, sagittal grade, length of injury, thoracolumbar injury classification system (TLICS), maximum canal compromise (MCC), and maximum spinal cord compression (MSCC) were collected. We performed an analytical workflow to detect multivariate PC patterns followed by explicit hypothesis testing to predict AIS at discharge. All imaging variables loaded positively on PC1 (64.3% of variance), which was highly related to AIS at discharge. MCC, MSCC, and TLICS also loaded positively on PC2 (22.7% of variance), while variables concerning cord signal abnormality loaded negatively on PC2. PC2 was highly related to the patient undergoing surgical decompression. Variables of signal abnormality were all negatively correlated with AIS at discharge with the highest level of correlation for axial grade as assessed with the Brain and Spinal Injury Center (BASIC) score. A multiple variable model identified BASIC as the only statistically significant predictor of AIS at discharge, signifying that BASIC best captured the variance in AIS within our study population. Our study provides evidence of convergent validity, construct validity, and clinical predictive validity for the sampled MRI measures of SCI when applied in acute thoracic and thoracolumbar SCI.

Profile of thoracic trauma victims submitted to chest drainage

Directory of Open Access Journals (Sweden)

CESAR AUGUSTO BROSKA JÚNIOR

Full Text Available ABSTRACT Objective: to describe and compare the variables involved in trauma victims undergoing thoracic drainage. Methods: we conducted a retrospective, analytical, descriptive, cross-sectional study, with medical records of patients attended at the Trauma Service of the Curitiba Evangelical University Hospital between February 2011 and January 2014. Results: there were 488 patients undergoing chest drainage, 84.7% men and 15.3% women, with an average age of 38.2 years. Attendances usually occurred at night, without predominance between open or closed mechanism, gender or age group. The majority of patients with thoracic trauma requiring drainage were diagnosed by anamnesis and physical examination (41.1% and drained in the emergency room (80.8%. Most of the patients (66.2% had another associated lesion, mostly some abdominal viscera. Complications were present in 16.6% (81 patients, most of them due to drainage positioning error (9.2%. The mean hospital stay was 15 days and drainage lasted for an average of 8.1 days, with no statistical difference between open and closed trauma. The clinical outcome was discharge in most cases. Conclusion: the profile of patients with thoracic trauma is that of young men, attended at night, with some other associated lesion. Although diagnosis and treatment were rapid and most often without the need for complex examinations, the time of drainage, hospitalization and complications were higher than in the literature, which can be explained by the drainage being made at the Emergency Room and the presence of associated injuries.

Objective: To evaluate the incidence of postoperative venous thromboembolism (VTE) after thoracic surgery and its characteristic. Methods: This was a single-center, prospective cohort study. Patients undergoing major thoracic surgeries between July 2016 and March 2017 at Department of Thoracic Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University were enrolled in this study. Besides the routine examination, all patients were screened for deep venous thrombosis (DVT) by using noninvasive duplex lower-extremity ultrasonography after surgery. CT pulmonary angiography (CTPA) was carried out if patients had one of the following conditions including typical symptoms of PE, high Caprini score (>9 points) or new diagnosed postoperative DVT. Caprini risk assessment model was used to detect high risk patients. No patients received any prophylaxis of VTE before surgery. Further data was analyzed for identifying the incidence of postoperative VTE. The t -test, χ 2 test or Wilcoxon rank-sum test was used to analyze the quantitative data and classification data, respectively. Results: Totally 345 patients who undergoing major thoracic surgery were enrolled in this study including 145 benign diseases and 200 malignant diseases.There were 207 male and 138 female, aging from 15 to 85 years. Surgery procedures included 285 lung surgeries, 27 esophagectomies, 22 mediastinal surgeries and 11 other procedures. The overall incidence of VTE was 13.9% (48 of 345) after major thoracic surgery including 39 patients with newly diagnosed DVT (81.2%), 1 patient with PE (2.1%) and 8 patients with DVT+ PE (16.7%). The median time of VTE detected was 4.5 days postoperative. There were 89.6% (43/48) VTE cases diagnosed in 1 week. The incidence of VTE was 9.0% in patients with benign diseases, while 17.5% in malignant diseases (χ 2 =5.112, P patients with pulmonary diseases was 12.6%, among that, in patients with lung cancer and benign lung diseases was 16.4% and 7.5 % (χ 2

Full Text Available Abstract Background Veno-arterial extracorporeal membrane oxygenation (ECMO is a common modality of circulatory assist device used in children. We assessed the outcome of children who had ECMO following repair of congenital cardiac defects (CCD and identified the risk factors associated with hospital mortality. Methods From April 1990 to December 2003, 53 patients required ECMO following surgical correction of CCD. Retrospectively collected data was analyzed with univariate and multivariate logistic regression analysis. Results Median age and weight of the patients were 150 days and 5.4 kgs respectively. The indications for ECMO were low cardiac output in 16, failure to wean cardiopulmonary bypass in 13, cardiac arrest in 10 and cardio-respiratory failure in 14 patients. The mean duration of ECMO was 143 hours. Weaning off from ECMO was successful in 66% and of these 83% were survival to hospital-discharge. 37.7% of patients were alive for the mean follow-up period of 75 months. On univariate analysis, arrhythmias, ECMO duration >168 hours, bleeding complications, renal replacement therapy on ECMO, arrhythmias and cardiac arrest after ECMO were associated with hospital mortality. On multivariate analysis, abnormal neurology, bleeding complications and arrhythmias after ECMO were associated with hospital mortality. Extra and intra-thoracic cannulations were used in 79% and 21% of patients respectively and extra-thoracic cannulation had significantly less bleeding complications (p = 0.031. Conclusion ECMO provides an effective circulatory support following surgical repair of CCD in children. Extra-thoracic cannulation is associated with less bleeding complications. Abnormal neurology, bleeding complications on ECMO and arrhythmias after ECMO are poor prognostic indicators for hospital survival.

BACKGROUND Despite national emphasis on care coordination, little is known about how fragmentation affects cancer surgery outcomes. Our study examines a specific form of fragmentation in post-discharge care—readmission to a hospital different from the location of the operation—and evaluates its causes and consequences among patients readmitted after major cancer surgery. STUDY DESIGN We used the State Inpatient Database of California (2004 to 2011) to identify patients who had major cancer surgery and their subsequent readmissions. Logistic models were used to examine correlates of non-index readmissions and to assess associations between location of readmission and outcomes, measured by in-hospital mortality and repeated readmission. RESULTS Of 9,233 readmissions within 30 days of discharge after major cancer surgery, 20.0% occurred in non-index hospitals. Non-index readmissions were associated with emergency readmission (odds ratio [OR] = 2.63; 95% CI, 2.26–3.06), rural residence (OR = 1.81; 95% CI, 1.61–2.04), and extensive procedures (eg hepatectomy vs proctectomy; OR = 2.77; CI, 2.08–3.70). Mortality was higher during non-index readmissions than index readmissions independent of patient, procedure, and hospital factors (OR = 1.31; 95% CI, 1.03–1.66), but was mitigated by adjusting for conditions present at readmission (OR = 1.24; 95% CI, 0.98–1.58). Non-index readmission predicted higher odds of repeated readmission within 60 days of discharge from the first readmission (OR = 1.16; 95% CI, 1.02–1.32), independent of all covariates. CONCLUSIONS Non-index readmissions constitute a substantial proportion of all readmissions after major cancer surgery. They are associated with more repeated readmissions and can be caused by severe surgical complications and increased travel burden. Overcoming disadvantages of non-index readmissions represents an opportunity to improve outcomes for patients having major cancer surgery. PMID:27016905

Anaesthetic and critical care management of thoracic injuries.

Round, J A; Mellor, A J

Thoracic wounding has been a relatively common presentation of military wounds throughout modern conflict. When civilian casualties are included the incidence has remained constant at around 10%, although the frequency and severity of wounds to combatants has been altered by modern body armour. Whilst thoracic injury has a high initial mortality on the battlefield, those surviving to reach hospital frequently have injuries that only require simple management. In addition to penetrating ballistic injury, blunt chest trauma frequently occurs on operations as a result of road traffic collisions or tertiary blast injury. The physiological impact of thoracic wounds, however, is often great and survivors often require intensive care management and, where available, complex strategies to ensure oxygenation and carbon dioxide removal. This review examines the incidence and patterns of thoracic trauma and looks at therapeutic options for managing these complex cases.

Both the Centers for Medicare and Medicaid Services' (CMS) Hospital Compare star rating and surgical case volume have been publicized as metrics that can help patients to identify high-quality hospitals for complex care such as cancer surgery. The current study evaluates the relationship between the CMS' star rating, surgical volume, and short-term outcomes after major cancer surgery. National Medicare data were used to evaluate the relationship between hospital star ratings and cancer surgery volume quintiles. Then, multilevel logistic regression models were fit to examine the association between cancer surgery outcomes and both star rankings and surgical volumes. Lastly, a graphical approach was used to compare how well star ratings and surgical volume predicted cancer surgery outcomes. This study identified 365,752 patients undergoing major cancer surgery for 1 of 9 cancer types at 2,550 hospitals. Star rating was not associated with surgical volume (P cancer surgery outcomes (mortality, complication rate, readmissions, and prolonged length of stay). The adjusted predicted probabilities for 5- and 1-star hospitals were 2.3% and 4.5% for mortality, 39% and 48% for complications, 10% and 15% for readmissions, and 8% and 16% for a prolonged length of stay, respectively. The adjusted predicted probabilities for hospitals with the highest and lowest quintile cancer surgery volumes were 2.7% and 5.8% for mortality, 41% and 55% for complications, 12.2% and 11.6% for readmissions, and 9.4% and 13% for a prolonged length of stay, respectively. Furthermore, surgical volume and the star rating were similarly associated with mortality and complications, whereas the star rating was more highly associated with readmissions and prolonged length of stay. In the absence of other information, these findings suggest that the star rating may be useful to patients when they are selecting a hospital for major cancer surgery. However, more research is needed before these ratings can

Cardiovascular complications are associated with increased mortality and morbidity during the postoperative period, resulting in longer hospital stay and higher treatment costs. The aim of this study was to identify predictors of major postoperative cardiac complications. 187 patients undergoing noncardiac surgery, admitted to a surgical intensive care unit (ICU) between November 2004 and April 2005. Variables recorded were age, gender, American Society of Anesthesiologists (ASA) physical status, type and magnitude of surgery, mortality, ICU and hospital length of stay (LOS), Simplified Acute Physiology Score II (SAPS II), cardiac troponin I (cTnI) at postoperative day 0, 1, 2 and 3, history of hypertension, hyperlipidemia, Revised Cardiac Risk Index (RCRI) score, major cardiac events (MCE): acute myocardial infarction (AMI), pulmonary edema (PE), ventricular fibrillation (VF) or primary cardiac arrest (PCA). Correlations between variables and MCE were made by univariate analysis by simple logistic regression with odds ratio (OR) and 95% confidence interval (95% CI). Total of 14 MCE: 9 AMI, 1 VF, 4 PE. Significant risk factors for MCE were high-risk surgery (OR 8.26, 95% CI 1.76-38.85, p = 0.008), RCRI > or = 2 (OR 4.0, 95% CI 1.22-13.16, p = 0.022), admission cTnI (OR 1.46, 95% CI 1.07-1.99, p = 0.018); day 1 cTnI (OR 1.75, 95% CI 1.27-2.41, p = 0.001); day 2 cTnI (OR 2.23, 95% CI 1.24-3.98, p = 0.007), SAPS II (OR 1.08, 95% CI 1.04-1.12, p or = 2, cTnI levels and SAPS II were predictors of postoperative MCE. Patients with MCE had longer ICU stay and higher mortality rate.

Although robotic technology has addressed many of the limitations of traditional videoscopic surgery, robotic surgery has not gained widespread acceptance in the general thoracic community. We report our initial robotic surgery experience and propose a structured, competency-based pathway for the development of robotic skills. Between December 2008 and February 2012, a total of 79 robot-assisted pulmonary, mediastinal, benign esophageal, or diaphragmatic procedures were performed. Data on patient characteristics and perioperative outcomes were retrospectively collected and analyzed. During the study period, one surgeon and three residents participated in a triphasic, competency-based pathway designed to teach robotic skills. The pathway consisted of individual preclinical learning followed by mentored preclinical exercises and progressive clinical responsibility. The robot-assisted procedures performed included lung resection (n = 38), mediastinal mass resection (n = 19), hiatal or paraesophageal hernia repair (n = 12), and Heller myotomy (n = 7), among others (n = 3). There were no perioperative mortalities, with a 20% complication rate and a 3% readmission rate. Conversion to a thoracoscopic or open approach was required in eight pulmonary resections to facilitate dissection (six) or to control hemorrhage (two). Fewer major perioperative complications were observed in the later half of the experience. All residents who participated in the thoracic surgery robotic pathway perform robot-assisted procedures as part of their clinical practice. Robot-assisted thoracic surgery can be safely learned when skill acquisition is guided by a structured, competency-based pathway.

Full Text Available The main goal of enhanced recovery program after thoracic surgery is to minimize stress response, reduce postoperative pulmonary complications, and improve patient outcome, which will in addition decrease hospital stay and reduce hospital costs. As minimally invasive technique, video-assisted thoracoscopic surgery represents an important element of enhanced recovery program in thoracic surgery. Anesthetic management during preoperative, intraoperative and postoperative period is essential for the enhanced recovery. In the era of enhanced recovery protocols, non-intubated thoracoscopic procedures present a step forward. This article focuses on the key elements of the enhanced recovery program in thoracic surgery. Having reviewed recent literature, the authors highlight potential procedures and techniques that might be incorporated into the program.

Manual treatments targeting different regions (shoulder, cervical spine, thoracic spine, ribs) have been studied to deal with patients complaining of shoulder pain. Thoracic manual treatments seem able to produce beneficial effects on this group of patients. However, it is not clear whether the patient improvement is a consequence of thoracic manual therapy or a placebo effect. To compare the efficacy of thoracic manual therapy and placebo thoracic manual treatment for patients with shoulder dysfunction. Electronic databases (MEDLINE, CENTRAL, PEDro, CINAHL, WoS, EMBASE, ERIC) were searched through November 2016. Randomized Controlled Trials assessing pain, mobility and function were selected. The Cochrane bias estimation tool was applied. Outcome results were either extracted or computed from raw data. Meta-analysis was performed for outcomes with low heterogeneity. Four studies were included in the review. The methodology of the included studies was generally good except for one study that was rated as high risk of bias. Meta-analysis showed no significant effect for "pain at present" (SMD -0.02; 95% CI: -0.35, 0.32) and "pain during movement" (SMD -0.12; 95% CI: -0.45, 0.21). There is very low to low quality of evidence that a single session of thoracic manual therapy is not more effective than a single session of placebo thoracic manual therapy in patients with shoulder dysfunction at immediate post-treatment.

Imaging of the thoracic duct is usually performed by radiological lymphography. However, this procedure, which uses an oil based dye injected directly into the lymph channels, has some adverse effects. In this paper we note that lymphoscintigraphy, a physiological and non invasive method, may visualize thoracic duct abnormalities, and might be particularly usefull when radiological lymphography is contraindicated.

To present our experience of staged correction with multiple cervical hemivertebra resection and thoracic pedicle subtraction osteotomy (PSO) treating a rare and complicated congenital scoliosis. A 14-year-old male presented with progressive torticollis and spine deformity. The malformation developed since birth, and back pain after long-time sitting or exercise arose since 6 months before, which was unsuccessfully treated by physiotherapy. X-ray showed a right cervical curve of 60° and a left compensatory thoracic curve of 90°. Three-dimensional computed tomography (3-D CT) scan revealed three semi-segmented hemivertebrae (C4, C5 and C6) on the right side. Based on our staged strategy, the three consecutive cervical hemivertebrae, as the major pathology causing the deformity, were firstly resected by the combined posterior and anterior approach. Six months later, T6 PSO osteotomy was used to correct the structural compensatory thoracic curve. The cervical curve was reduced to 23° while the thoracic curve to 60° after the first-stage surgery, and the thoracic curve was further reduced to 30° after the second-stage surgery. The radiograph at 5-year follow-up showed that both the coronal and sagittal balance were well restored and stabilized, with the occipital tilt reduced from 12° to 0°. Our strategy may provide an option for similar cases with multiple consecutive cervical hemivertebrae and a large structural compensatory thoracic curve, which proved to achieve excellent correction in both the coronal and sagittal planes with acceptable neurologic risk.

We report a case of vascular thoracic outlet syndrome in a young man, diagnosed with upper limb arteriography, leading to repeated arterio-arterial emboli originating from a post-stenotic subclavian artery aneurysm. It is of our interest due to its low incidence and the small number of cases reported that have been diagnosed by arteriography. The thoracic outlet is the path through which vascular and neural structures goes from the neck to the axilla, and it has three anatomical strictures, that when pronounced, can compress the brachial plexus or subclavian vessels, leading to different symptoms and signs.

Objective: To explore the clinical staging of moderately advanced and advanced thoracic esophageal carcinoma by evaluating the prognosis and provide criteria for individual treatment. Methods: The authors retrospectively analyzed 500 patients with moderately advanced and advanced thoracic esophageal carcinoma treated by radiotherapy alone. According to the primary lesion length by barium meal X-ray film, the invasion range and the relation between location and the surrounding organs by CT scans the disease category was classified by a 6 stage method and a 4 stage method. With the primary lesion divide into T1, T2a, T2b, T3a, T3b and T4 incorporating the locregional lymph node metastasis, a 6 stage system was obtained, I, IIa , IIb, IIIa, IIIb and IV. The results of this as compared with those of 4 stage system, the following data were finally arrived at. Results: Among the 500 cases, there were T1 23, T2a 111, T2b 157, T3a 84, T3b 82 and T4 43. The survival rates of these six categories showed significant differences (χ 2 =63.32, P 2 =56.29, P 2 =94.29, P 2 =83.48, P<0.05). Conclusions: Both the 6 stage and 4 stage systems are adaptable to predict prognosis of moderately advanced and advanced esophageal carcinoma treated by radiotherapy alone. For simplicity and convenience, the 4 stage classification is recommended. (authors)

This study reports the challenges faced by French military surgeons in the management of thoracic injury during the latest Afghanistan war. From January 2009 to April 2013, all of the civilian, French and Coalition casualties admitted to French NATO Combat Support Hospital situated on Kabul were prospectively recorded in the French Military Health Service Registry (OPEX(®)). Only penetrating and blunt thoracic trauma patients were retrospectively included. Eighty-nine casualties were included who were mainly civilian (61%) and men (94%) with a mean age of 27.9 years old. Surgeons dealt with polytraumas (78%), severe injuries (mean Injury Severity Score=39.2) and penetrating wounds (96%) due to explosion in 37%, gunshot in 53% and stabbing in 9%. Most of casualties were first observed or drained (n=56). In this non-operative group more than 40% of casualties needed further actions. In the operative group, Damage Control Thoracotomy (n=22) was performed to stop ongoing bleeding and air leakage and Emergency Department Thoracotomy (n=11) for agonal patient. Casualties suffered from hemothorax (60%), pneumothorax (39%), diaphragmatic (37%), lung (35%), heart or great vessels (20%) injuries. The main actions were diaphragmatic sutures (n=25), lung resections (wedge n=6, lobectomy n=4) and haemostasis (intercostal artery ligation n=3, heart injury repairs n=5, great vessels injury repairs n=5). Overall mortality was 11%. The rate of subsequent surgery was 34%. The analysis of the OPEX(®) registry reflects the thoracic surgical challenges of general (visceral) surgeons serving in combat environment during the latest Afghanistan War.

To assess the morphology of thoracic aorta, we had a trial of Gd-DTPA enhanced ultrafast cine MR imaging on the thoracic aorta. This method was provided with high quality thoracic aortogram during 15-20 seconds. In patients without hypertension and aortic valve disease, dimensions of ascending aorta and aortic arch were significantly correlated with aging. In patients with hypertension, dimensions of ascending aorta and aortic arch were significantly dilated. In patients with aortic valve disease, thoracic aorta was diffusely enlarged, especially in ascending aorta. Gd-DTPA enhanced ultrafact cine MR imaging was useful to assess the thoracic aortic anatomy and diseases. (author)

1984-05-01

All lateral chest radiographs of 34 persons with posterior longitudinal ligament ossification (PLLO) in the thoracic spine were reviewed for date of its onset and its progress. These observations spanned as long as 18 years. Upper mid-thoracic PLLO first appeared under the age of 40, then increased in extent in the vertical axis until the age of 50. Lower thoracic PLLO occurred later than upper mid-thoracic PLLO. In the lower thoracic and lumbar regions, degeneration of the vertebrae and discs apparently were focal factors which triggered the development of thoracic PLLO. PLLO apparently developed in a different way in the upper and mid-thoracic regions, where the vertebrae and discs were unremarkable at the time of its initial appearance, and degenerative abnormalities did not predispose to it.

Surgical site infection (SSI) complicates approximately 2% of surgeries in the Veterans Affairs (VA) hospitals. Surgical site infections are responsible for increased morbidity, length of hospital stay, cost, and mortality. Surgical site infection can be minimized by modifying risk factors. In this study, we identified risk factors and developed accurate predictive surgical specialty-specific SSI risk prediction models for the Veterans Health Administration (VHA) surgery population. In a retrospective observation study, surgical patients who underwent surgery from October 2013 to September 2016 from 136 VA hospitals were included. The Veteran Affairs Surgical Quality Improvement Program (VASQIP) database was used for the pre-operative demographic and clinical characteristics, intra-operative characteristics, and 30-day post-operative outcomes. The study population represents 11 surgical specialties: neurosurgery, urology, podiatry, otolaryngology, general, orthopedic, plastic, thoracic, vascular, cardiac coronary artery bypass graft (CABG), and cardiac valve/other surgery. Multivariable logistic regression models were developed for the 30-day post-operative SSIs. Among 354,528 surgical procedures, 6,538 (1.8%) had SSIs within 30 days. Surgical site infection rates varied among surgical specialty (0.7%-3.0%). Surgical site infection rates were higher in emergency procedures, procedures with long operative duration, greater complexity, and higher relative value units. Other factors associated with increased SSI risk were high level of American Society of Anesthesiologists (ASA) classification (level 4 and 5), dyspnea, open wound/infection, wound classification, ascites, bleeding disorder, chemotherapy, smoking, history of severe chronic obstructive pulmonary disease (COPD), radiotherapy, steroid use for chronic conditions, and weight loss. Each surgical specialty had a distinct combination of risk factors. Accurate SSI risk-predictive surgery specialty

MRI-based anatomical landmarks for the identification of thoracic vertebral levels

Connor, S.E.J.; Shah, A.; Latifoltojar, H.; Lung, P.

2013-01-01

Aim: To identify soft-tissue and bony anatomical landmarks on dedicated thoracic spine magnetic resonance imaging (MRI), and to assess their detectability, reproducibility, and accuracy in predicting specific thoracic vertebral levels. Materials and methods: One hundred dedicated thoracic MRI studies were retrospectively analysed by two radiologists independently. Ten bone and soft-tissue landmarks were localized to the adjacent vertebral level. The true numerical thoracic vertebral level was subsequently determined and recorded by cross referencing with a sagittal cervico-thoracic “counting scan”. Results: Six landmarks were defined in ≥98% cases; however, there was a low interobserver percentage agreement for the defined vertebral levels (>70% for only one landmark). The most useful landmark for defining a specific vertebral level was the most superior rib (98% detection, 95% interobserver agreement, 98% at a single vertebral level, 0.07 SD). Eight landmarks localized to a specific thoracic segment in only 16–44% of cases, with a standard deviation of >0.5 vertebral levels and with a range which was greater than four vertebral levels. Conclusion: The C2 vertebra must be identified and cross referenced to the dedicated thoracic spine MRI, as other MRI-based anatomical landmarks are unreliable in determining the correct thoracic vertebral level

Surgical treatment of infective and prosthetic endocarditis using allografts gives good results. Aortic allograft implantation is a common technique, while tricuspid valve replacement with a mitral allograft is very rare. Multiple valve disease in case of infective endocarditis is a surgical challenge as such patients are usually in a grave condition and results of surgical treatment are often unsatisfactory. In this article we describe a clinical case of successful surgical treatment in a patient with active infective endocarditis of aortic and tricuspid valve, complicated by an aortic-right ventricular fistula. The aortic valve and ascending aorta were replaced with a cryopreserved aortic allograft; the tricuspid valve was replaced with a cryopreserved mitral allograft. © The Author 2015.

Thoracic splenosis as a differential diagnosis of juxtapleural nodules

Directory of Open Access Journals (Sweden)

B. Lopes

2014-01-01

Full Text Available Thoracic splenosis is rare and consists of ectopic implantation of splenic tissue into the chest after concomitant thoracic and abdominal trauma with diaphragm injury. It occurs in about 18% of cases of splenic ruptures. In almost all cases, diagnosis is given incidentally once patients are usually asymptomatic. Thoracic splenosis should be considered as a differential diagnosis in all patients with history of trauma presenting with juxtapleural nodules in chest computed tomography. However, malignant conditions should be ruled out firstly. Biopsy is not essential for the diagnosis once nuclear medicine can confirm splenosis in patients with pertinent history of trauma and suggestive tomographic image. We present a typical case of thoracic splenosis whose diagnosis was made by nuclear medicine and no invasive procedures were required.

The aim of this retrospective study was to evaluate the clinical outcome of patients with spinal dural arteriovenous fistulas (SDAVFs) that were treated with surgery, catheter embolization, or surgery after incomplete embolization. The study included 21 consecutive patients with SDAVFs of the thoracic, lumbar, or sacral spine who were treated in our institution from 1994 to 2007. Thirteen patients were treated with catheter embolization alone. Four patients underwent hemilaminectomy and intradural interruption of the fistula. Four patients were treated by endovascular techniques followed by surgery. The clinical outcome was assessed using the modified Aminoff-Logue scale (ALS) for myelopathy and the modified Rankin scale (MRS) for general quality of life. Patient age ranged from 44 to 77 years (mean 64.7 years). Surgical as well as endovascular treatment resulted in a significant improvement in ALS (-62.5% and -31.4%, respectively, p<0.05) and a tendency toward improved MRS (-50% and -32%, respectively) scores. Patients that underwent surgery after endovascular treatment due to incomplete occlusion of the fistula showed only a tendency for improvement in the ALS score (-16.7%), whereas the MRS score was not affected. We conclude that both endovascular and surgical treatment of SDAVFs resulted in a good and lasting clinical outcome in the majority of cases. In specific situations, when a secondary neurosurgical approach was required after endovascular treatment to achieve complete occlusion of the SDAVF, the clinical outcome was rather poor. The best first line treatment modality for each individual patient should be determined by an interdisciplinary team. (orig.)

Internal Thoracic Artery Encircled by an Unusual Phrenic Nerve Loop

2007-12-01

Full Text Available We report an anatomic variation of the phrenic nerve. During a routine gross anatomical dissection course at our medical university, we found an unusual loop of the left phrenic nerve around the internal thoracic artery, about 1 cm from the take-off of the left subclavian artery. The phrenic nerve is close to the internal thoracic artery and is easily injured when dissecting the internal thoracic artery for coronary artery bypass conduit. Therefore, we suggest that the anatomic relationship of the phrenic nerve and internal thoracic artery is important in preventing incidental injury of the phrenic nerve.

Primary epidural malignant hemangiopericytoma of thoracic spinal column causing cord compression: case report

Directory of Open Access Journals (Sweden)

Mohammad Mohammadianpanah

Full Text Available CONTEXT: Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare. CASE REPORT: We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.

Isolated Juvenile Xanthogranuloma in Thoracic Spine: Intraoperative Cytological Diagnosis of a Rare Presentation

Full Text Available Juvenile Xanthogranulomas (JXG are benign proliferative disorders of non-Langerhans histiocytes, which present in children as multiple, self-limited, cutaneous lesions. The extracutaneous manifestations of JXG are uncommon, and isolated JXG involving the spinal column is extremely rare. We report here a case of isolated juvenile xanthogranuloma in thoracic spine correctly diagnosed intraoperatively on crush smear cytology and later confirmed by histopathological and immunohistochemical studies. This case report draws attention to the fact that isolated xanthogranuloma should be considered among possible diagnoses of spinal tumor in children. Also, since the long term survival depends on complete surgical resection, a correct intraoperative diagnosis is extremely important for optimal management and prognosis of the patient.

Michael Goodman

2013-01-01

Full Text Available Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13% following blunt injury and 20 (87% after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury.

Thoracic complications of rheumatoid disease

Rheumatoid arthritis is a relatively common multisystem disease associated with significant mortality and morbidity. Thoracic disease, both pleural and pulmonary, is a frequent extra-articular manifestation of rheumatoid arthritis and responsible for approximately 20% of rheumatoid-associated mortality. Rheumatoid disease and its associated therapies can affect all compartments of the lung inciting a range of stereotyped pathological responses and it is not infrequent for multiple disease entities to co-exist. In some instances, development of pulmonary complications may precede typical rheumatological presentation of the disease and be the first indication of an underlying connective tissue disease. The spectrum of thoracic disease related to rheumatoid arthritis is reviewed

Lung herniation is a rare condition defined as a protrusion of the pleural-covered lung parenchyma through an abnormal defect or weakness in the thoracic wall. Postoperative lung herniation is reported to result from a preceding operation with inadequate closure of the chest wall. A 77-year-old woman was admitted to our hospital for treatment of hemoptysis and nausea. One year previously, she had undergone wedge resection of the right lower lobe (S6) for treatment of primary lung adenocarcinoma. Upon admission, chest radiograph and chest computed tomography showed a right lung herniation through the fifth enlarged intercostal space with right fifth and sixth rib fractures. She underwent surgical closure of the intercostal hernia using synthetic materials with fixation of the fifth and sixth ribs. The patient had developed no recurrence 9 months after surgical repair. In the present case, adequate closure of the right pleural cavity was ensured by fixation of both fifth and sixth ribs during the preceding video-assisted thoracic surgery for the primary lung carcinoma. Our patient may have had some exacerbation factors for lung herniation, increased intrathoracic pressure, attenuation of chest wall by prolonged coughing and rib fracture, and high abdominal pressure due to her hunched-over posture. It is important to know some exacerbation factors for postoperative intercostal lung herniation. Addition of monofirament-suture fixation of the ribs to patch repair is very effective for lung herniation repair in patients with concurrent lung herniation and rib fractures.

Treatment of bilateral mammary ptosis and pectus excavatum through the same incision in one surgical stage

Directory of Open Access Journals (Sweden)

Fernando Passos Rocha

Full Text Available CONTEXT: Congenital deformities of the anterior thoracic wall are characterized by unusual development of the costal cartilages. All these medical conditions are frequently associated with a variety of breast deformities. Several surgical techniques have been described for correcting them, going from sternochondroplasty to, nowadays, minimally invasive techniques and silicone prosthesis implantation. CASE REPORT: The present article reports the case of a young female patient who presented bilateral mammary ptosis and moderate pectus excavatum that caused a protrusion between the eighth and the tenth ribs and consequent esthetic disharmony. The proposed surgical treatment included not only subglandular breast implants of polyurethane, but also resection of part of the rib cartilage and a bone segment from the eighth, ninth and tenth ribs by means of a single submammary incision in order to make the scar minimally visible. Correction through a single incision benefited the patient and provided an excellent esthetic result. CONCLUSIONS: The techniques used to repair bilateral mammary ptosis and pectus excavatum by plastic and thoracic surgery teams, respectively, have been shown to be efficient for correcting both deformities. An excellent esthetic and functional result was obtained, with consequent reestablishment of the patient's self-esteem.

The aim of this study was to assess clinical and contemporary costs associated with elective endovascular repair of intact descending thoracic aortic aneurysms (DTAA) into the mid-term follow-up. A retrospective review of a prospectively maintained clinical database including 29 consecutive patients from July 2005 to December 2009 treated with elective endovascular repair (TEVAR) or TEVAR and surgical infrarenal repair (hybrid) of intact DTAA was performed. Mean age was 74.5 years old (±7.1). Primary clinical endpoints include mortality and major morbidity. Additionally a comprehensive economic appraisal of individual in-hospital and follow-up costs was executed. Economic endpoints include in-hospital and follow-up costs and patient discharge status. Elective endovascular and open repairs' clinical and economical outcomes in contemporary literature were assessed for comparison according to PRISMA standards. Immediate mortality was 6.9% (1/24 TEVAR and 1/5 hybrid). Three respiratory complications were recorded (11%; 2 TEVAR, 1 hybrid). Renal and cardiac complication rates were 7.4% (1 TEVAR, 1 hybrid) and 3.7% (1 TEVAR) respectively. Routine discharge home was achieved for 85% of patients (95.7% TEVAR, 25% hybrid). Three endoleaks were treated throughout the follow-up (2 TEVAR, 1 hybrid; mean 30.4 mo, ±19.9) rendering an 11% (3/27) reintervention rate. Average immediate cost was €21,976.87 for elective endovascular repair and €33,783.21 for elective endovascular hybrid repair. Additional reintervention and routine follow-up costs augmented immediate costs by 12.4%. This study supports satisfying immediate clinical outcomes for TEVAR and TEVAR+surgical infrarenal procedures. Although limited by a small population size and difficulties in economic comparisons, this study presents the real world social and economic cost scenario for both elective TEVAR and TEVAR hybrid treatment of DTAA of both the in-hospital and at mid term follow-up periods.

A RARE CASE OF THORACIC ACTINOMYCOSIS

Priyanka Das

2017-10-01

Full Text Available PRESENTATION OF CASE Actinomycetes are branching gram-positive anaerobic bacteria belonging to Actinomycetaceae family and are commensals in human oropharynx, gastrointestinal tract and female genitalia. Thoracic or pulmonary actinomycosis is an uncommon bacterial infection. The diagnosis of pulmonary or thoracic actinomycosis is often confounding because of its shared clinical features with malignant lung diseases and chronic suppurative lung diseases. However, chest physicians should be aware of actinomycosis being a differential diagnosis in persistent shadows in lung as early diagnosis leads to good prognosis. 1

Controversy exists regarding the effects of multilevel facetectomy and screw density on deformity correction, especially thoracic kyphosis (TK) restoration in adolescent idiopathic scoliosis (AIS) surgery. This study aimed to evaluate the effects of multilevel facetectomy and screw density on sagittal plane correction in patients with main thoracic (MT) AIS curve. A retrospective correlation and comparative analysis of prospectively collected, consecutive, non-randomized series of patients at a single institution was undertaken. Sixty-four consecutive patients with Lenke type 1 AIS treated with posterior correction and fusion surgery using simultaneous double-rod rotation technique were included. Patient demographics and preoperative and 2-year postoperative radiographic measurements were the outcome measures for this study. Multiple stepwise linear regression analysis was conducted between change in TK (T5-T12) and the following factors: age at surgery, Risser sign, number of facetectomy level, screw density, preoperative main thoracic curve, flexibility in main thoracic curve, coronal correction rate, preoperative TK, and preoperative lumbar lordosis. Patients were classified into two groups: TKcorrect hypokyphosis. Copyright © 2016 Elsevier Inc. All rights reserved.

With the increasing use of thoracic computed tomography (CT) to screen for injuries in pediatric blunt thoracic trauma (BTT), we determined whether chest x-ray (CXR) and other clinical and epidemiologic variables could be used to predict significant thoracic injuries, to inform the selective use of CT in pediatric BTT. We further queried if these were discrepant from factors associated with the decision to obtain a thoracic CT. This retrospective cohort study included cases of BTT from three Level I pediatric trauma centers between April 1999 and March 2008. Pre-CT epidemiologic, clinical, and radiologic variables associated with CT findings of any thoracic injury or a significant thoracic injury as well as the decision to obtain a thoracic CT were determined using logistic regression. Of 425 patients, 40% patients had a significant thoracic injury, 49% had nonsignificant thoracic injury, and 11% had no thoracic injury at all. Presence of hydrothorax and/or pneumothorax on CXR significantly increased the likelihood of significant chest injury visualized by CT (adjusted odds ratio 10.8; 95% confidence interval, 6.5-18), as did the presence of isolated subcutaneous emphysema (adjusted odds ratio, 19.8; 95% confidence interval, 2.3-168). Although a normal CXR finding was not statistically associated with a reduced risk of significant thoracic injury, 8 of the 9 cases with normal CXR findings and significant injuries involved occult pneumothoraces or hemothoraces not requiring intervention. Converse to features suggesting increased risk of significant injury, the decision to obtain a thoracic CT was only associated with later period in the study and obtaining a CT scan of another body region. CXR can be used to screen for significant thoracic injuries and direct the selective use of thoracic CT in pediatric BTT. Prospective studies are needed to validate these findings and develop guidelines that include CXR to define indications for thoracic CT in pediatric BTT

Increased pixel noise and streak artifact reduce CT image quality and limit the potential for radiation dose reduction during CT of the thoracic inlet. We propose to quantify the pixel noise of mediastinal structures in the thoracic inlet, during low-dose (LDCT) and ultralow-dose (uLDCT) thoracic CT, and assess the utility of new software (quantum denoising system and BOOST3D) in addressing these limitations. Twelve patients had LDCT (120 kV, 25 mAs) and uLDCT (120 kV, 10 mAs) images reconstructed initially using standard mediastinal and lung filters followed by the quantum denoising system (QDS) to reduce pixel noise and BOOST3D (B3D) software to correct photon starvation noise as follows: group 1 no QDS, no B3D; group 2 B3D alone; group 3 QDS alone and group 4 both QDS and B3D. Nine regions of interest (ROIs) were replicated on mediastinal anatomy in the thoracic inlet, for each patient resulting in 3456 data points to calculate pixel noise and attenuation. QDS reduced pixel noise by 18.4% (lung images) and 15.8% (mediastinal images) at 25 mAs. B3D reduced pixel noise by ∼8% in the posterior thorax and in combination there was a 35.5% reduction in effective radiation dose (E) for LDCT (1.63-1.05 mSv) in lung images and 32.2% (1.55-1.05 mSv) in mediastinal images. The same combination produced 20.7% reduction (0.53-0.42 mSv) in E for uLDCT, for lung images and 17.3% (0.51-0.42) for mediastinal images. This quantitative analysis of image quality confirms the utility of dedicated processing software in targeting image noise and streak artifact in thoracic LDCT and uLDCT images taken in the thoracic inlet. This processing software potentiates substantial reductions in radiation dose during thoracic LDCT and uLDCT.

Benchmarking entails continuous comparison of efficacy and quality among products and activities, with the primary objective of achieving excellence. To analyze the results of benchmarking performed in 2013 on clinical practices undertaken in 2012 in 17 Spanish thoracic surgery units. Study data were obtained from the basic minimum data set for hospitalization, registered in 2012. Data from hospital discharge reports were submitted by the participating groups, but staff from the corresponding departments did not intervene in data collection. Study cases all involved hospital discharges recorded in the participating sites. Episodes included were respiratory surgery (Major Diagnostic Category 04, Surgery), and those of the thoracic surgery unit. Cases were labelled using codes from the International Classification of Diseases, 9th revision, Clinical Modification. The refined diagnosis-related groups classification was used to evaluate differences in severity and complexity of cases. General parameters (number of cases, mean stay, complications, readmissions, mortality, and activity) varied widely among the participating groups. Specific interventions (lobectomy, pneumonectomy, atypical resections, and treatment of pneumothorax) also varied widely. As in previous editions, practices among participating groups varied considerably. Some areas for improvement emerge: admission processes need to be standardized to avoid urgent admissions and to improve pre-operative care; hospital discharges should be streamlined and discharge reports improved by including all procedures and complications. Some units have parameters which deviate excessively from the norm, and these sites need to review their processes in depth. Coding of diagnoses and comorbidities is another area where improvement is needed. Copyright © 2015 SEPAR. Published by Elsevier Espana. All rights reserved.

To determine the presentation and management outcome of thoracic trauma in a tertiary care setting. A total of 143 patients, who presented with chest trauma, were included in the study. All the patients were assessed by the history, physical examination and ancillary investigations. Appropriate managements were instituted as required. Data was described in percentages. out of 143 patients, 119 (83)% were males and 24 (17)% were females. Most of the patients belonged to the age group of 21-50 years. Ninety seven (66)% patients were admitted for indoor management. Blunt injury was found in 125 (87.4%) patients, while penetrating injuries in only 18 (12.6%) patients. Road Traffic Accidents (RTAs) were the commonest cause of trauma (n=103, 72%). Rib fracture was the commonest chest injury (74% patients). Head injury was the most frequently associated injury (18% of the patients). Tube thoracostomy was the commonest intervention undertaken in 65 (45%) patients. Seventeen (11.88%) patients were managed with mechanical ventilation. there were 17 deaths with a mortality rate of 11.88%. Thoracic trauma is an important cause of hospitalization, morbidity and mortality in the younger population. RTAs constitute the leading cause of thoracic trauma in our setup. Tube thoracostomy is the most frequent and at times the only invasive procedure required as a definitive measure in thoracic trauma patients. A policy of selective hospitalization helps to avoid unnecessary hospital admissions. (author)

Image-guided pedicle screw placement in the cervico-thoracic region is a commonly applied technique. In some patients with deformed cervico-thoracic segments, conventional or 3D fluoroscopy based registration of image-guidance might be difficult or impossible because of the anatomic/pathological conditions. Landmark based registration has been used as an alternative, mostly using separate registration of each vertebra. We here investigated a routine for landmark based registration of rigid spinal segments as single objects, using cranial image-guidance software. Landmark based registration of image-guidance was performed using cranial navigation software. After surgical exposure of the spinous processes, lamina and facet joints and fixation of a reference marker array, up to 26 predefined landmarks were acquired using a pointer. All pedicle screws were implanted using image guidance alone. Following image-guided screw placement all patients underwent postoperative CT scanning. Screw positions as well as intraoperative and clinical parameters were retrospectively analyzed. Thirteen patients received 73 pedicle screws at levels C6 to Th8. Registration of spinal segments, using the cranial image-guidance succeeded in all cases. Pedicle perforations were observed in 11.0%, severe perforations of >2 mm occurred in 5.4%. One patient developed a transient C8 syndrome and had to be revised for deviation of the C7 pedicle screw. No other pedicle screw-related complications were observed. In selected patients suffering from pathologies of the cervico-thoracic region, which impair intraoperative fluoroscopy or 3D C-arm imaging, landmark based registration of image-guidance using cranial software is a feasible, radiation-saving and a safe alternative.

To investigate the diagnostic value of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in detecting thoracic aortic prosthetic graft infection. Nine patients with clinically suspected thoracic aortic graft infection underwent FDG-PET/CT scanning. In these patients, the diagnoses could not be confirmed using conventional modalities. The patients' clinical courses were retrospectively reviewed. On the basis of surgical, microbiological and clinical follow-up findings, the aortic grafts were considered infected in 4 patients and not infected in 5. All 4 patients with graft infection (root: 2 cases, arch: 1 case and descending: 1 case) eventually underwent in situ re-replacement. Two of the 4 patients also had abdominal grafts; however, only the thoracic grafts were replaced because uptake was low around the abdominal grafts. The maximal standardized uptake value (SUVmax) in the perigraft area was higher in the infected group than in the non-infected group (11.4 ± 4.5 vs 6.9 ± 6.4), although the difference was not statistically significant. According to the receiver operating characteristic analysis, SUVmax >8 appeared to be the cut-off value in distinguishing the two groups (sensitivity: 1.0 and specificity: 0.8). FDG-PET/CT is useful for confirming the presence of graft infection by detecting high uptake around grafts and excluding other causes of inflammation. An SUVmax value greater than 8 around a graft suggests the presence of graft infection. In addition, FDG-PET/CT can be used to clarify the precise extent of infection. This is especially useful if multiple separated prosthetic grafts have been implanted.

OBJECTIVES The frequent and prolonged use of thoracoscopic equipment raises ergonomic risks which may cause physical distress. We aimed to determine the relationship between ergonomic problems encountered in thoracoscopic surgery and physical distress among thoracic surgeons. METHODS An online questionnaire which investigated personal factors, product factors, interaction factors and physical discomfort was sent to all members of the European Society of Thoracic Surgeons (ESTS). RESULTS Of the respondents, 2.4% indicated that a one arm's length should be the optimal distance between the surgeon and the monitor. Only 2.4% indicated that the monitor should be positioned below the eye level of the surgeon. Most of the respondents agreed, partially to fully, that they experienced neck discomfort because of inappropriate monitor height, bad monitor position and bad table height. Most respondents experienced numb fingers and shoulder discomfort due to instrument manipulation. Most of the respondents (77.1%) experienced muscle fatigue to some extent due to a static posture during thoracoscopic surgery. The majority of respondents (81.9, 76.3 and 83.2% respectively) indicated that they had varying degrees of discomfort mainly in the neck, shoulder and back. Some 94.4% of respondents were unaware of any guidelines concerning table height, monitor and instrument placement for endoscopic surgery. CONCLUSIONS Most thoracic surgeons in Europe are unaware of ergonomic guidelines and do not practise them, hence they suffer varying degrees of physical discomfort arising from ergonomic issues.

To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established. One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6 +/- 14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion. Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affected level of the upper thoracic spine, with 15 bulge/protrusions and one extrusion. Upper degenerative thoracic disc contour changes presented in older patients than the cervical levels (Student-Newman-Keuls test, P < 0.001). Degenerative disc contour changes at the C7-T1, T1-2, T2-3 and T3-4 levels were significantly correlated ( P = 0.001), but unrelated to any other disc disease, patient's gender or age. Degenerative cervical disc disease was closely related together ( P < 0.001), but not with any thoracic disc. A statistically significant relation was found within the upper thoracic discs, reflecting common pathoanatomical changes. The absence of relation to cervical segments is probably due to differences in their pathomechanisms.

The incidence rate of prolonged air leak (PAL) after lobectomy, defined as any air leak prolonged beyond 7 days, can be estimated to be in between 6 and 15%. In 2011, the Epithor group elaborated an accurate predictive score for PAL after open lung resections, so-called IPAL (index of prolonged air leak), from a nation-based surgical cohort constituted between 2004 and 2008. Since 2008, video-assisted thoracic surgery (VATS) has become popular in France among the thoracic surgical community, reaching almost 14% of lobectomies performed with this method in 2012. This minimally invasive approach was reported as a means to reduce the duration of chest tube drainage. The aim of our study was thus to validate the IPAL scoring system in patients having received VATS anatomical lung resections. We collected all anatomical VATS lung resections (lobectomy and segmentectomy) registered in the French national general thoracic surgery database (EPITHOR) between 2009 and 2012. The area under the receiver operating characteristic (ROC) curve estimated the discriminating value of the IPAL score. The slope value described the relation between the predicted and observed incidences of PALs. The Hosmer-Lemeshow test was also used to estimate the quality of adequacy between predicted and observed values. A total of 1233 patients were included: 1037 (84%) lobectomies and 196 (16%) segmentectomies. In 1099 cases (89.1%), the resection was performed for a malignant disease. Ninety-six patients (7.7%) presented with a PAL. The IPAL score provided a satisfactory predictive value with an area under the ROC curve of 0.72 (0.67-0.77). The value of the slope, 1.25 (0.9-1.58), and the Hosmer-Lemeshow test (χ(2) = 11, P = 0.35) showed that predicted and observed values were adequate. The IPAL score is valid for the estimation of the predictive risk of PAL after VATS lung resections. It may thus a priori be used to characterize any surgical population submitted to potential preventive measures

Despite being commonly affected by degenerative disorders, there are few data on normal thoracic intervertebral disc dimensions. A morphometric analysis of adult thoracic intervertebral discs was, therefore, undertaken. Archival computed tomography scans of 128 recently deceased individuals (70 males, 58 females, 20-79 years) with no known spinal pathology were analysed to determine thoracic disc morphometry and variations with disc level, sex and age. Reliability was assessed by intraclass correlation coefficients (ICCs). Anterior and posterior intervertebral disc heights and axial dimensions were significantly greater in men (anterior disc height 4.0±1.4 vs 3.6±1.3 mm; posterior disc height 3.6±0.90 vs 3.4±0.93 mm; p<0.01). Disc heights and axial dimensions at T4-5 were similar or smaller than at T2-3, but thereafter increased caudally (mean anterior disc height T4-5 and T10-11, 2.7±0.7 and 5.4±1.2 mm, respectively, in men; 2.6±0.8 and 5.1±1.3 mm, respectively, in women; p<0.05). Except at T2-3, anterior disc height decreased with advancing age and anteroposterior and transverse disc dimensions increased; posterior and middle disc heights and indices of disc shape showed no consistent statistically significant changes. Most parameters showed substantial to almost perfect agreement for intra- and inter-rater reliability. Thoracic disc morphometry varies significantly and consistently with disc level, sex and age. This study provides unique reference data on adult thoracic intervertebral disc morphometry, which may be useful when interpreting pathological changes and for future biomechanical and functional studies.

Case report. Thoracic spine thrust manipulation has been shown to be an effective intervention for individuals experiencing mechanical neck pain. The patient was a 46-year-old woman referred to outpatient physical therapy 2 months following multiple-level anterior cervical discectomy and fusion. At initial evaluation, primary symptoms consisted of frequent headaches, neck pain, intermittent referred right elbow pain, and muscle fatigue localized to the right cervical and upper thoracic spine regions. Initial examination findings included decreased passive joint mobility of the thoracic spine, limited cervical range of motion, and limited right shoulder strength. Outcome measures consisted of the numeric pain rating scale, the Neck Disability Index, and the global rating of change scale. Treatment consisted of a combination of manual therapy techniques aimed at the thoracic spine, therapeutic exercises for the upper quarter, and patient education, including a home exercise program, over a 6-week episode of care. Immediate reductions in cervical-region pain (mean ± SD, 2.0 ± 1.1) and headache (2.0 ± 1.3) intensity were reported every treatment session immediately following thoracic spine thrust manipulation. At discharge, the patient reported 0/10 cervical pain and headache symptoms during all work-related activities. From initial assessment to discharge, Neck Disability Index scores improved from 46% to 16%, with an associated global rating of change scale score of +7 ("a very great deal better"). This case report describes the immediate and short-term clinical outcomes for a patient presenting with symptoms of neck pain and headache following anterior cervical discectomy and fusion surgical intervention. Clinical rationale and patient preference aided the decision to incorporate thoracic spine thrust manipulation as a treatment for this patient. Level of Evidence Therapy, level 4.

2017-01-01

Full Text Available Introduction. Chylothorax is an accumulation of chyle in the pleural cavity due to a disruption of the thoracic duct. Traumatic chylothoraces are usually a result of a penetrating trauma and disruption of the thoracic duct, but blunt traumatic chylothorax is a rare condition. The aim of this paper is to present a rare case of traumatic chylothorax after blunt thoracic trauma. Case Outline. We present a case of traumatic chylothorax after blunt thoracic trauma in a patient injured in a motor vehicle accident. The patient had a right-sided fracture of rib XI, hydropneumothorax, lung contusion, and signs of pneumomediastinum. We performed thoracic drainage, but a few days later, according to the increase of amount of the fluid daily drained, and the confirmation of laboratory findings of the analyzed fluid, we made a diagnosis of chylothorax and the patient underwent a thoracotomy, where we sutured the thoracic duct. Conclusion. Chylothorax should be considered in patients after chest trauma if they develop a milky pleural effusion. Analysis of pleural fluid and level of triglycerides is important for the diagnosis and treatment of chylothorax.

There is growing experimental evidence that beta-endorphin immunoreactivity is raised by surgical stress in patients undergoing general anesthesia. As the assay methods employed to date did not allow to fully discriminate between beta-endorphin and its immediate precursor, beta-lipotropin, the authors have investigated in the present study plasma levels of these two peptides by separating them by chromatography on plasma extracts prior to radioimmunoassay. Beta-lipotropin, but not beta-endorphin, plasma levels were found to be significantly elevated during surgery in the general anesthesia group, while no change was found in either peptide concentration in the spinal one. Cortisol plasma levels also increased significantly 90 minutes after the beginning of surgery. Although the sampling time they adopted may have prevented them from detecting an early peak of beta-endorphin during the first 30 minutes of surgery, the major component of the pituitary opioid response to surgical stress appears to be related to beta-lipotropin. This is in agreement with results of experimental work on various kinds of stress in animals and humans and seems to rule out a role for plasma beta-endorphin in post-operative analgesia. 38 references, 1 figure, 1 table.

Measurement of worker exposure to a thoracic health-related aerosol fraction is necessary in a number of occupational situations. This is the case of workplaces with atmospheres polluted by fibrous particles, such as cotton dust or asbestos, and by particles inducing irritation or bronchoconstriction such as acid mists or flour dust. Three personal and two static thoracic aerosol samplers were tested under laboratory conditions. Sampling efficiency with respect to particle aerodynamic diameter was measured in a horizontal low wind tunnel and in a vertical calm air chamber. Sampling performance was evaluated against conventional thoracic penetration. Three of the tested samplers performed well, when sampling the thoracic aerosol at nominal flow rate and two others performed well at optimized flow rate. The limit of flow rate optimization was found when using cyclone samplers. © The Author 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

Current Treatments for Surgically Resectable, Limited-Stage, and Extensive-Stage Small Cell Lung Cancer.

2017-12-01

The prevalence of small cell lung cancer (SCLC) has declined in the U.S. as the prevalence of tobacco use has declined. However, a significant number of people in the U.S. are current or former smokers and are at risk of developing SCLC. Routine histological or cytological evaluation can reliably make the diagnosis of SCLC, and immunohistochemistry stains (thyroid transcription factor-1, chromogranin, synaptophysin, and CD56) can be used if there is uncertainty about the diagnosis. Rarely do patients present with SCLC amendable to surgical resection, and evaluation requires a meticulous workup for extra-thoracic metastases and invasive staging of the mediastinum. Resected patients require adjuvant chemotherapy and/or thoracic radiation therapy (TRT), and prophylactic cranial radiation (PCI) should be considered depending on the stage. For limited-stage disease, concurrent platinum-etoposide and TRT followed by PCI is the standard. Thoracic radiation therapy should be started early in treatment, and can be given twice daily to 45 Gy or once daily to 60-70 Gy. For extensive-stage disease, platinum-etoposide remains the standard first-line therapy, and the standard second-line therapy is topotecan. Preliminary studies have demonstrated the activity of immunotherapy, and the response rate is approximately 10-30% with some durable responses observed. Rovalpituzumab tesirine, an antibody drug conjugate, has shown promising activity in patients with high delta-like protein 3 tumor expression (approximately 70% of patients with SCLC). The emergence of these and other promising agents has rekindled interest in drug development in SCLC. Several ongoing trials are investigating novel agents in the first-line, maintenance, and second-line settings. This review will provide an update on the standard therapies for surgically resected limited-stage small cell lung cancer and extensive-stage small cell lung cancer that have been investigated in recent clinical trials. © Alpha

Lung cancer is the leading cause of cancer death in the United States, accounting for 28% of all cancer deaths. Standard of care for potentially curable lung cancer involves preoperative radiographic or invasive staging, followed by surgical resection. With recent adjuvant chemotherapy and radiation studies showing a survival advantage in nodepositive patients, it is crucial to accurately stage these patients surgically in order to identify those who may benefit. However, lymphadenectomy in lung cancer is currently performed without guidance, mainly due to the lack of tools permitting real-time, intraoperative identification of lymph nodes. In this study we report the design and validation of a novel, clinically compatible near-infrared (NIR) fluorescence thoracoscope for real-time intraoperative guidance during lymphadenectomy. A novel, NIR-compatible, clinical rigid endoscope has been designed and fabricated, and coupled to a custom source and a dual channel camera to provide simultaneous color and NIR fluorescence information to the surgeon. The device has been successfully used in conjunction with a safe, FDA-approved fluorescent tracer to detect and resect mediastinal lymph nodes during thoracic surgery on Yorkshire pigs. Taken together, this study lays the foundation for the clinical translation of endoscopic NIR fluorescence intraoperative guidance and has the potential to profoundly impact the management of lung cancer patients.

Improving patient safety seems to be a new interesting clinical subject but, in fact, it is no new. It has to do with one of the oldest ethical principles of our profession: curing and not harming. The important research that has been done in a short period of time has brought in new insight to this complex area that is fast developing. The creation of safety managing systems will allow coordinating efforts from very different, although complementary, areas to create real safety culture and safety climate in every organization. In the surgical settings, teamwork is basic to provide good quality of care. Safety leaders in every team have an important role in establishing priorities, summarizing proposals, coordinating efforts, launching new initiatives and transmitting that safety efforts are worth taken. Preparedness and anticipation are key points for avoiding most of the diverse types of patient harm that can occur. As has been published, a great number of errors can be avoided simply using crosscheck based on specialized checklist that reviews every important detail of the procedure. This strategy has been demonstrated very useful at other high risk industries such as aviation, nuclear or food management. The Safe Surgery Saves Lives program launched in 2002 by the WHO has taught us that improvement is possible using a simple checklist. More complex and detail checklist can be more adequate for more complex procedures and settings. The proposed ESTS checklist reviews different areas of possible error in deeper detail allowing the finest adjustment of the patient before the skin incision. It has been recently released to the general thoracic community and monitors its use and usefulness has to be warrantied.

Background Jeune asphyxiating thoracic dystrophy (JATD) is a rare, often lethal, recessively inherited chondrodysplasia characterised by shortened ribs and long bones, sometimes accompanied by polydactyly, and renal, liver and retinal disease. Mutations in intraflagellar transport (IFT) genes cause JATD, including the IFT dynein-2 motor subunit gene DYNC2H1. Genetic heterogeneity and the large DYNC2H1 gene size have hindered JATD genetic diagnosis. Aims and methods To determine the contribution to JATD we screened DYNC2H1 in 71 JATD patients JATD patients combining SNP mapping, Sanger sequencing and exome sequencing. Results and conclusions We detected 34 DYNC2H1 mutations in 29/71 (41%) patients from 19/57 families (33%), showing it as a major cause of JATD especially in Northern European patients. This included 13 early protein termination mutations (nonsense/frameshift, deletion, splice site) but no patients carried these in combination, suggesting the human phenotype is at least partly hypomorphic. In addition, 21 missense mutations were distributed across DYNC2H1 and these showed some clustering to functional domains, especially the ATP motor domain. DYNC2H1 patients largely lacked significant extra-skeletal involvement, demonstrating an important genotype–phenotype correlation in JATD. Significant variability exists in the course and severity of the thoracic phenotype, both between affected siblings with identical DYNC2H1 alleles and among individuals with different alleles, which suggests the DYNC2H1 phenotype might be subject to modifier alleles, non-genetic or epigenetic factors. Assessment of fibroblasts from patients showed accumulation of anterograde IFT proteins in the ciliary tips, confirming defects similar to patients with other retrograde IFT machinery mutations, which may be of undervalued potential for diagnostic purposes.

The aim of this study was to assess the relationship between radiation therapy (RT) and treatment-related mortality in patients receiving high-dose chemotherapy (HDCT) and autologous bone marrow transplantation (ABMT) for recurrent/refractory Hodgkin's disease (HD). Between December 1986 and December 1992, 59 patients previously treated at the Princess Margaret Hospital underwent HDCT (etoposide 60 mg/kg, melphalan 160 mg/m 2 ) and ABMT, performed for refractory (13 patients) or relapsed (46 patients) HD. RT was incorporated in the salvage treatment with the intent to achieve complete control of disease prior to ABMT. RT was given before ABMT in 33 patients, and after ABMT in 4 patients. Treatment-related (TR) mortality was defined as any death occurring within 100 days of ABMT. Autopsies were performed for all patients with TR deaths. With a median follow-up of 4.6 years (range 1.2-7.4 years), the actuarial overall survival was 41%±14% at 5 years. We observed 37 deaths, and 10 of these were TR deaths. Among the 24 patients who received thoracic RT before ABMT, there were 8 TR deaths, 3 of these solely attributable to radiation pneumonitis. The remaining 5 TR deaths all had respiratory failure with complicating sepsis as a major medical problem. The interval from RT to ABMT was shorter for 8 patients dying of TR death (mean 37 days; range 0-103 days), than for the 16 survivors (mean 105 days; range 0-263 days) (P=0.026). Among 9 patients with ABMT within 50 days of thoracic RT, 6 had TR death. In contrast, among the 35 patients without thoracic RT (26 no RT, 9 non-thoracic RT), there were only 2 TR deaths. The 4 patients treated with mantle RT post-ABMT had no serious pulmonary complications. The use of thoracic RT before HDCT and ABMT was associated with a high post-transplant mortality rate. It was most evident in patients who received thoracic RT within 50 days prior to ABMT, or when the target volume included large volume of lung. We recommend that the use of

Full Text Available Abstract Background Trunk asymmetry and vertebral rotation, at times observed in the normal spine, resemble the characteristics of adolescent idiopathic scoliosis (AIS. Right thoracic curvature has also been reported in the normal spine. If it is determined that the features of right thoracic side curvature in the normal spine are the same as those observed in AIS, these findings might provide a basis for elucidating the etiology of this condition. For this reason, we investigated right thoracic curvature in the normal spine. Methods For normal spinal measurements, 1,200 patients who underwent a posteroanterior chest radiographs were evaluated. These consisted of 400 children (ages 4-9, 400 adolescents (ages 10-19 and 400 adults (ages 20-29, with each group comprised of both genders. The exclusion criteria were obvious chest and spinal diseases. As side curvature is minimal in normal spines and the range at which curvature is measured is difficult to ascertain, first the typical curvature range in scoliosis patients was determined and then the Cobb angle in normal spines was measured using the same range as the scoliosis curve, from T5 to T12. Right thoracic curvature was given a positive value. The curve pattern was organized in each collective three groups: neutral (from -1 degree to 1 degree, right (> +1 degree, and left ( Results In child group, Cobb angle in left was 120, in neutral was 125 and in right was 155. In adolescent group, Cobb angle in left was 70, in neutral was 114 and in right was 216. In adult group, Cobb angle in left was 46, in neutral was 102 and in right was 252. The curvature pattern shifts to the right side in the adolescent group (p Conclusions Based on standing chest radiographic measurements, a right thoracic curvature was observed in normal spines after adolescence.

Guidelines for repair of bicuspid aortic valve-associated ascending thoracic aortic aneurysms have been changing, most recently to the same criteria as tricuspid aortic valve-ascending thoracic aortic aneurysms. Rupture/dissection occurs when wall stress exceeds wall strength. Recent studies suggest similar strength of bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms; thus, comparative wall stress may better predict dissection in bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms. Our aim was to determine whether bicuspid aortic valve-ascending thoracic aortic aneurysms had higher wall stresses than their tricuspid aortic valve counterparts. Patients with bicuspid aortic valve- and tricuspid aortic valve-ascending thoracic aortic aneurysms (bicuspid aortic valve = 17, tricuspid aortic valve = 19) greater than 4.5 cm underwent electrocardiogram-gated computed tomography angiography. Patient-specific 3-dimensional geometry was reconstructed and loaded to systemic pressure after accounting for prestress geometry. Finite element analyses were performed using the LS-DYNA solver (LSTC Inc, Livermore, Calif) with user-defined fiber-embedded material model to determine ascending thoracic aortic aneurysm wall stress. Bicuspid aortic valve-ascending thoracic aortic aneurysms 99th-percentile longitudinal stresses were 280 kPa versus 242 kPa (P = .028) for tricuspid aortic valve-ascending thoracic aortic aneurysms in systole. These stresses did not correlate to diameter for bicuspid aortic valve-ascending thoracic aortic aneurysms (r = -0.004) but had better correlation to tricuspid aortic valve-ascending thoracic aortic aneurysms diameter (r = 0.677). Longitudinal stresses on sinotubular junction were significantly higher in bicuspid aortic valve-ascending thoracic aortic aneurysms than in tricuspid aortic valve-ascending thoracic aortic aneurysms (405 vs 329 kPa, P = .023).

Full Text Available Background: A major challenge in the postoperative period is pain management which, if not adequately controlled, may contribute to patient discomfort and decreased patient satisfaction, and possibly increased morbidity and mortality. Both Thoracic paravertebral block and oblique subcostal transversus abdominis plane block can be used as analgesic techniques for abdominal surgeries. Our aim in this research was comparison of cumulative 24-h post-operative morphine consumption between ultrasound-guided oblique subcostal transversus abdominis plane block and ultrasound-guided thoracic paravertebral block in patients who underwent an open cholecystectomy under general anesthesia. Patients and methods: This study was performed on 46 patients who underwent open cholecystectomy under general anesthesia. All patients were randomly allocated alternatively to one of two equal groups to either undergo ultrasound-guided unilateral oblique subcostal transversus abdominis plane block Group (I or to undergo ultrasound-guided unilateral thoracic paravertebral block Group (II. Both groups were subjected to a similar analgesic regimen in the immediate post-operative period that involved intravenous patient-controlled morphine analgesia which was used in both groups. Results: The total morphine consumption in the first postoperative 24 h was lower in thoracic paravertebral block Group (II (9.9 mg in thoracic paravertebral block group vs. 15.4 mg in oblique subcostal transversus abdominis plane block Group (I with p < 0.001. The mean time of first request of analgesia in Group (I was 248.7 min compared to 432.1 for Group (II with p < 0.001. Conclusions: Both ultrasound-guided oblique subcostal transversus abdominis plain block and single injection ultrasound guided thoracic paravertebral block are effective analgesic techniques for upper abdominal surgeries and reduces postoperative opioid requirements. However, thoracic paravertebral block is more

The Askin tumours is an extremely rare and malignant process in the thoracic pulmonary region during infancy and youth. The differential diagnosis has to be considered with other thoracic wall tumours that are more common in pediatrics like the undifferentiated neuroblastoma, the embionic rabdomiosarcoma, the Ewing sarcoma and the linfoma. A retrospective examination was carried out on 473 thoracic wall tumours from 1994 to 1997 at our centre, resulting in 4 patients with an anatomopathologically tested Askin tumour (ages from 13-21). All the cases were studied using simple radiography and CT. In two cases MRI was also used. The most common clinical manifestation was a palpable painful mass in the thoracic wall. In the simple radiograph the main finding was a large mass of extrapleural soft material, with costal destruction ( n=3) and a pleural effusion (n=2). In the CT study the mass was heterogeneous, with internal calcifications in one case. CT and MRI showed invasion in the mediastinum (n=1), medular channel (n=1) and phrenic and sulphrenic extension (n=1). The Askin tumour should be included in the differential diagnosis of thoracic wall masses in infant-youth ages. There are no specific morphological characteristics. Both CT and MRI are useful for the diagnosis, staging and follow up. (Author) 11 refs

The purpose of the current study is to present the clinical and surgical results in patients who underwent hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection. Thirty-one patients, 27 men and 4 women, underwent segmental-main bronchial sleeve anastomoses for non-small cell lung cancer between May 2004 and May 2011. Twenty-six (83.9%) patients had squamous cell carcinoma, and 5 patients had adenocarcinoma. Six patients were at stage IIB, 24 patients at stage IIIA, and 1 patient at stage IIIB. Secondary sleeve anastomosis was performed in 18 patients, and Y-shaped multiple sleeve anastomosis was performed in 8 patients. Single segmental bronchiole anastomosis was performed in 5 cases. The average time for chest tube removal was 5.6 days. The average length of hospital stay was 11.8 days. No anastomosis fistula developed in any of the patients. The 1-, 2-, and 3-year survival rates were 83.9%, 71.0%, and 41.9%, respectively. Hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection is a complex technique that requires training and experience, but it is an effective and safe operation for selected patients.

Full Text Available BACKGROUND AND OBJECTIVES: In this study, we aimed to clarify the importance of residency grade and other factors which influence the success of thoracic epidural catheterization in thoracotomy patients. METHODS: After the ethical committee approval, data were recorded retrospectively from the charts of 415 patients. All patients had given written informed consent. The thoracic epidural catheterization attempts were divided into two groups as second-third year (Group I and fourth year (Group II according to residency grade. We retrospectively collected demographic data, characteristics of thoracic epidural catheterization attempts, and all difficulties and complications during thoracic epidural catheterization. RESULTS: Overall success rate of thoracic epidural catheterization was similar between the groups. Levels of catheter placement, number and duration of thoracic epidural catheterization attempts were not different between the groups (p > 0.05. Change of needle insertion level was statistically higher in Group II (p = 0.008, whereas paresthesia was significantly higher in Group I (p = 0.007. Dural puncture and postdural puncture headache rates were higher in Group I. Higher body mass index and level of the insertion site were significant factors for thoracic epidural catheterization failure and postoperative complication rate and those were independence from residents' experience (p < 0.001, 0.005. CONCLUSION: Body mass index and level of insertion site were significant on thoracic epidural catheterization failure and postoperative complication rate. We think that residents' grade is not a significant factor in terms overall success rate of thoracic epidural catheterization, but it is important for outcome of these procedures.

The da Vinci Surgical System has been used in only a few cases for treating mediastinal tumors in Japan. Recently, we used the da Vinci Surgical System for various types of anterior and middle mediastinal tumors in clinical practice. We report our early experience using the da Vinci Surgical System. Seven patients gave written informed consent to undergo robotic surgery for mediastinal tumor dissection using the da Vinci Surgical System. We evaluated the safety and feasibility of this system for the surgical treatment of mediastinal tumors. Two specialists in thoracic surgery who are certified to use the da Vinci S Surgical System and another specialist acted as an assistant performed the tumor dissection. We were able to access difficult-to-reach areas, such as the mediastinum, safely. All the resected tumors were classified as benign tumors histologically. The average da Vinci setting time was 14.0 min, the average working time was 55.7 min, and the average overall operating time was 125.9 min. The learning curve for the da Vinci setup and manipulation time was short. Robotic surgery enables mediastinal tumor dissection in certain cases more safely and easily than conventional video-assisted thoracoscopic surgery and less invasively than open thoracotomy.

This article presents a 56-year-old obese female who presented with back pain and progressive weakness in her lower limbs for three months. She was bed-ridden for one week before reporting to our hospital. Plain radiographs showed vertical striations in multiple vertebrae classical of haemangioma. Magnetic resonance imaging (MRI) spine revealed multiple thoracic and lumbar vertebral haemangiomas. Extra osseous extension of haemangioma at T12 was causing spinal cord compression. Two-stage surgery was performed with absolute alcohol (ethanol) injection followed by pedicle screw fixation and decompression with tricortical iliac crest bone graft into the vertebral body. Postoperatively rapid neurological improvement was seen. After three weeks, she could walk independently. One year later, computed tomography showed complete incorporation of bone graft and maintained vertebral body height. MRI showed complete resolution of the cord edema at T12. These findings indicated diminished vascularity of the tumor. PMID:25187869

This article presents an overview of factors associated with thoracic transplantation outcomes over the past decade and provides valuable information regarding the heart, lung, and heart-lung waiting lists and thoracic organ transplant recipients. Waiting list and post-transplant information is used to assess the importance of patient demographics, risk factors, and primary cardiopulmonary disease on outcomes. The time that the typical listed patient has been waiting for a heart, lung, or heart-lung transplant has markedly increased over the past decade, while the number of transplants performed has declined slightly and survival after transplant has plateaued. Waiting list mortality, however, appears to be declining for each organ and for most diseases and high-severity subgroups, perhaps in response to recent changes in organ allocation algorithms. Based on perceived inequity in organ access and in response to a mandate from Health Resources and Services Administration, the lung transplant community is developing a lung allocation system designed to minimize deaths on the waiting list while maximizing the benefit of transplant by incorporating post-transplant survival and quality of life into the algorithm. Areas where improved data collection could inform evolving organ allocation and candidate selection policies are emphasized.

This study aimed to assess the technical feasibility, procedural safety, and long-term therapeutic efficacy of a small-sized ambulatory thoracic vent (TV) device for the treatment of pneumothorax. From November 2012 to July 2013, 18 consecutive patients (3 females, 15 males) aged 16-64 years (mean: 34.7 ± 14.9 years, median: 29 years) were enrolled prospectively. Of these, 15 patients had spontaneous pneumothorax and 3 had iatrogenic pneumothorax. A Tru-Close TV with a small-bore (11- or 13-Fr) catheter was inserted under bi-plane fluoroscopic assistance. Technical success was achieved in all patients. Complete lung re-expansion was achieved at 24 hours in 88.9% of patients (16/18 patients). All patients tolerated the procedure and no major complications occurred. The patients' mean numeric pain intensity score was 2.4 (range: 0-5) in daily life activity during the TV treatment. All patients with spontaneous pneumothorax underwent outpatient follow-up. The mean time to TV removal was 4.7 (3-13) days. Early surgical conversion rate of 16.7% (3/18 patients) occurred in 2 patients with incomplete lung expansion and 1 patient with immediate pneumothorax recurrence post-TV removal; and late surgical conversion occurred in 2 of 18 patients (11.1%). The recurrence-free long-term success rate was 72.2% (13/18 patients) during a 3-year follow-up period from November 2012 to June 2016. TV application was a simple, safe, and technically feasible procedure in an outpatient clinic, with an acceptable long-term recurrence-free rate. Thus, TV could be useful for the immediate treatment of pneumothorax.

Cardiovascular disease is the primary cause of morbidity and mortality in the western world. Complex hemodynamics plays a critical role in the development of aortic dissection and atherosclerosis, as well as many other diseases. Since fundamental fluid mechanics are important for the understanding of the blood flow in the cardiovascular circulatory system of the human body aspects, a joint experimental and numerical study was conducted in this study to determine the distributions of wall shear stress and pressure and oscillatory WSS index, and to examine their correlation with the aortic disorders, especially dissection. Experimentally, the Phase-Contrast Magnetic Resonance Imaging (PC-MRI) method was used to acquire the true geometry of a normal human thoracic aorta, which was readily converted into a transparent thoracic aorta model by the rapid prototyping (RP) technique. The thoracic aorta model was then used in the in vitro experiments and computations. Simulations were performed using the computational fluid dynamic (CFD) code ACE+((R)) to determine flow characteristics of the three-dimensional, pulsatile, incompressible, and Newtonian fluid in the thoracic aorta model. The unsteady boundary conditions at the inlet and the outlet of the aortic flow were specified from the measured flowrate and pressure results during in vitro experiments. For the code validation, the predicted axial velocity reasonably agrees with the PC-MRI experimental data in the oblique sagittal plane of the thoracic aorta model. The thorough analyses of the thoracic aorta flow, WSSs, WSS index (OSI), and wall pressures are presented. The predicted locations of the maxima of WSS and the wall pressure can be then correlated with that of the thoracic aorta dissection, and thereby may lead to a useful biological significance. The numerical results also suggest that the effects of low WSS and high OSI tend to cause wall thickening occurred along the inferior wall of the aortic arch and the

2018-01-01

Background Research investigating Whiplash Associated Disorder (WAD) has largely focused on the cervical spine yet symptoms can be widespread. Thoracic spine pain prevalence is reported ~66%; perhaps unsurprising given the forceful stretch/eccentric loading of posterior structures of the spine, and the thoracic spine’s contribution to neck mobility/function. Approximately 50% WAD patients develop chronic pain and disability resulting in high levels of societal and healthcare costs. It is time to look beyond the cervical spine to fully understand anatomical dysfunction in WAD and provide new directions for clinical practice and research. Purpose To evaluate the scope and nature of dysfunction in the thoracic region in patients with WAD. Methods A systematic review and data synthesis was conducted according to a pre-defined, registered (PROSPERO, CRD42015026983) and published protocol. All forms of observational study were included. A sensitive topic-based search strategy was designed from inception to 1/06/16. Databases, grey literature and registers were searched using a study population terms and key words derived from scoping search. Two reviewers independently searched information sources, assessed studies for inclusion, extracted data and assessed risk of bias. A third reviewer checked for consistency and clarity. Extracted data included summary data: sample size and characteristics, outcomes, and timescales to reflect disorder state. Risk of bias was assessed using the Newcastle-Ottawa Scale. Data were tabulated to allow enabling a semi-qualitative comparison and grouped by outcome across studies. Strength of the overall body of evidence was assessed using a modified GRADE. Results Thirty eight studies (n>50,000) which were conducted across a range of countries were included. Few authors responded to requests for further data (5 of 9 contacted). Results were reported in the context of overall quality and were presented for measures of pain or dysfunction and

Practice guidelines reflect published literature. Because of the ever changing literature base, it is necessary to update and revise guideline recommendations from time to time. The Society of Thoracic Surgeons recommends review and possible update of previously published guidelines at least every three years. This summary is an update of the blood conservation guideline published in 2007. The search methods used in the current version differ compared to the previously published guideline. Literature searches were conducted using standardized MeSH terms from the National Library of Medicine PUBMED database list of search terms. The following terms comprised the standard baseline search terms for all topics and were connected with the logical 'OR' connector--Extracorporeal circulation (MeSH number E04.292), cardiovascular surgical procedures (MeSH number E04.100), and vascular diseases (MeSH number C14.907). Use of these broad search terms allowed specific topics to be added to the search with the logical 'AND' connector. In this 2011 guideline update, areas of major revision include: 1) management of dual anti-platelet therapy before operation, 2) use of drugs that augment red blood cell volume or limit blood loss, 3) use of blood derivatives including fresh frozen plasma, Factor XIII, leukoreduced red blood cells, platelet plasmapheresis, recombinant Factor VII, antithrombin III, and Factor IX concentrates, 4) changes in management of blood salvage, 5) use of minimally invasive procedures to limit perioperative bleeding and blood transfusion, 6) recommendations for blood conservation related to extracorporeal membrane oxygenation and cardiopulmonary perfusion, 7) use of topical hemostatic agents, and 8) new insights into the value of team interventions in blood management. Much has changed since the previously published 2007 STS blood management guidelines and this document contains new and revised recommendations. Copyright © 2011 The Society of Thoracic

Correction of gynecomastia in males is a frequently performed aesthetic procedure. Various surgical options involving the removal of excess skin, fat, or glandular tissue have been described. However, poor aesthetic outcomes, including a flat or depressed pectoral area, limit the success of these techniques. The authors sought to determine patient satisfaction with the results of upper chest augmentation by direct intrapectoral fat injection in conjunction with surgical correction of gynecomastia. In this prospective study, 26 patients underwent liposuction and glandular excision, glandular excision alone, or Benelli-type skin excision. All patients received intramuscular fat injections in predetermined zones of the pectoralis major (PM). The mean volume of fat injected was 160 mL (range, 80-220 mL per breast) bilaterally. Patients were monitored for an average of 16 months (range, 8-24 months). Hematoma formation and consequent infraareolar depression was noted in 1 patient and was corrected by secondary lipografting. Mean patient satisfaction was rated as 8.4 on a scale of 1 (unsatisfactory) to 10 (highly satisfactory). Autologous intrapectoral fat injection performed simultaneously with gynecomastia correction can produce a masculine appearance. The long-term viability of fat cells injected into the PM needs to be determined. 4 Therapeutic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

Nanotechnology is an emerging field with potential as an adjunct to cancer therapy, particularly thoracic surgery. Therapy can be delivered to tumors in a more targeted fashion, with less systemic toxicity. Nanoparticles may aid in diagnosis, preoperative characterization, and intraoperative localization of thoracic tumors and their lymphatics.

To examine the expression of interleukin-1β and interferon-γ and their possible roles in aortic dissections and aneurysms. Aortic specimens were obtained from patients with type I thoracic aortic dissection, ascending thoracic aortic aneurysms, and control organ donors. The expression of interleukin-1β, interferon-γ, matrix metalloproteinase-9, and signal transduction factors phospho-p38 and phosphorylated c-jun N-terminal kinase (phospho-JNK) were detected by real time reverse transcription-polymerase chain reaction (real time RT-PCR), Western blot, and immunohistochemistry, respectively. Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining was performed to detect apoptosis of media cells. The correlation of these factors and apoptosis was also studied. Apoptosis in the media of thoracic aortic dissection and in ascending thoracic aortic aneurysms was dramatically higher than in the control group. The expression of interleukin-1β gradually increased from the control group, thoracic aortic dissection to ascending thoracic aortic aneurysms (p matrix metalloproteinase-9 was significantly increased in the media of thoracic aortic dissection and ascending thoracic aortic aneurysms compared with the control group (p correlations between interleukin-1β versus matrix metalloproteinase-9, interleukin-1β versus phospho-p38 in thoracic aortic dissection (p matrix metalloproteinase-9, interferon-γ versus phospho-JNK, interferon-γ versus apoptosis, and interleukin-1β versus apoptosis in ascending thoracic aortic aneurysms (p = 0.02, 0.02, p matrix metalloproteinase-9 and the apoptosis of media cells in humans.

Cervical scar contracture causes both physical and psychological distress for burn patients. Many pedicle flaps or skin grafting have been suggested for reconstruction of cervical scar contracture with variable results in the literature. The authors present the axial thoracic flap based on the thoracic branch of the supraclavicular artery (TBSA) for reconstruction of cervical scar contracture. Postburn scar contractures in anterior neck region of 66 patients had been reconstructed with the axial pattern thoracic flaps based on the TBSA, including 1 expanded and 10 nonexpanded pedicle flaps, and 9 expanded and 46 nonexpanded island pedicle flaps, during 1988 through 2012. After removing and releasing the cervical scar contracture, the flap was designed in the thoracic region. The axial artery of the flap is the TBSA bifurcating from the intersection point of sternocleidomastoid muscle and omohyoid muscle with several concomitant veins as the axial veins. The flap can be designed in a large area within the borders of the anterior border of the trapezius muscle superiorly, the middle part of the deltoid muscle laterally, the midsternal line medially, and the level 3 to 4 cm below nipples inferiorly. After incisions were made along the medial, inferior, and lateral border, dissection was performed toward the pedicle. Donor site was closed directly in expanded cases and with skin grafting in nonexpanded cases. Cervical scar contractures were repaired with good functional and cosmetic results in 64 cases among this cohort. Flap tip necrosis in other 2 cases, caused by postoperative hematoma, was repaired by skin grafting. The color and texture of all flaps were fitted with those of the surrounding skin. The donor sites all healed primarily. The flap sensation in the thoracic region regained in the early stage postoperatively and that in cervical area recovered completely after 6 months according to the report of the patients. With reliable blood supply based on the

Full Text Available Background and objective Primary neuroendocrine carcinoma of thymus (pNECT is a rare thymic neoplasm. Some pNECTs could produce an adrenocorticotropic hormone and cause Cushing syndrome (CS. The aim os this study is to discuss the diagnostic technique and surgical management of pNECT-caused CS and analyze prognosis factors to improve the clinical experience of the disease. Methods The outcome of surgery and follow-up of 14 cases (eight males and six females of pNECT-caused CS were retrospectively analyzed from November 1987 to June 2013. Result The median age of the patients was 29, and the median duration of the disease was four months (1 month-44 months. All cases exhibited clinical evidence for the diagnosis of CS, and thoracic computed tomography (CT was used to detect thymic tumors. Surgical treatment significantly decreased the concentration of both serum cortisol and adrenocorticotropic hormone (P<0.01 but caused one death in the perioperative period. With multidisciplinary therapy, the median survival was 38 months. Conclusion pNECT-caused CS is a rare disease with aggressive characteristics and unclear prognosis. Early diagnosis and therapy is a challenge for clinicians. Thoracic CT is important for disease location and preoperative evaluation and should be routinely applied to all CS patients to allow early surgery and improved prognosis.

Three models of care are described, including two models of multidisciplinary care for thoracic malignancies. The pros and cons of each model are discussed, the evidence supporting each is reviewed, and the need for more (and better) research into care delivery models is highlighted. Key stakeholders in thoracic oncology care delivery outcomes are identified, and the need to consider stakeholder perspectives in designing, validating and implementing multidisciplinary programs as a vehicle for quality improvement in thoracic oncology is emphasized. The importance of reconciling stakeholder perspectives, and identify meaningful stakeholder-relevant benchmarks is also emphasized. Metrics for measuring program implementation and overall success are proposed.

This case study describes the process of examination, re-examination, and intervention for a collegiate runner with mechanical thoracic pain preventing athletic participation and limiting daily function. Unimpaired function fully returned in less than 3 weeks with biweekly sessions to re-establish normal and painfree thoracic mechanics via postural hygiene, exercise, mobilization, and manipulation. The outcome of this case study supports the original hypothesis that the pattern of impairments was in fact responsible for the functional limitations and disability in this athlete. At the time of publication the athlete was without functional limitations and had fully returned to competitive sprinting for the university track team.

Suppose that it were a generalizable finding, in both densely populated and rural states, that there is marked heterogeneity among hospitals in the percentage change in surgical caseload and/or in the total change in caseload. Then, individual hospitals should not simply rely on federal and state forecasts to infer their expected growth. Likewise, individual hospitals and their anesthesiology groups would best not rely on national or US regional surgical trends as causal reasons for local trends in caseload. We examined the potential utility of using state data on surgical caseload to predict local growth by using 6 years of data for surgical cases performed at hospitals in the States of Florida and Iowa. Observational cohort study. 303 hospitals in Iowa and Florida. Cases with major therapeutic procedures in 2010 or 2011 were compared pairwise by hospital with such cases in 2015 and 2016. Changes in counts of cases were decreases or increases, while study of growth set decreases equal to zero. Hospitals in Iowa had slightly lesser percentage changes than did hospitals in Florida (Mann-Whitney P = 0.016). Hospitals in Iowa had greater variability among hospitals in the change in counts of cases with a major therapeutic procedure than did hospitals in Florida (P < 0.0001). The 10% of hospitals with the largest growths in counts of cases accounted for approximately half of the total growth in Iowa (70%) and Florida (54%). The large share of total growth attributable to the upper 10th percentile of hospitals was not caused solely by the hospitals having large percentage growths, based on there being weak correlation between growth and percentage growth, among the hospitals that grew (Iowa: Kendall's tau = 0.286 [SE 0.120]; Florida tau = 0.253 [SE 0.064]). Even if the data from states or federal agencies reported growth in surgical cases, there is too much concentration of growth at a few hospitals for statewide growth rates to be useful for

To assess the long-term outcome of blunt trauma patients with suspected thoracic aortic or great vessel injury that was evaluated with contrast-enhanced chest computed tomography (CT). We studied the outcome of 278 consecutive patients who received contrast enhanced CT for blunt chest trauma with computerized searches of the regional trauma database, hospital medical records, universal government medical coverage plan billing records, and regional vital statistics databases. Data retrieved included patient demographics, mechanism of injury, status of the aorta and proximal great vessels at contrast-enhanced CT, hospital discharge diagnoses, and outpatient procedural billings with specific attention to aortic or great vessel injury. Median follow-up was 615 days following the traumatic event. Six subjects demonstrated direct signs of aortic or proximal great vessel injury on contrast-enhanced chest CT, as follows: aortic pseudoaneurysm and intimal flap (n = 4), carotid artery dissection (n = 1), and aortic dissection (n 1). All were surgically treated, except the patient with aortic dissection, who was treated medically. In the other subjects, contrast-enhanced CT was negative (n = 230) or showed isolated mediastinal hematoma (n = 42). The computerized searches of the medical databases showed that none of these 272 subjects had procedures for, or died from, aortic or great vessel injury during the follow-up period. Computerized searches of medical databases found no evidence of missed thoracic aortic or proximal great vessel injury in blunt trauma patients who were evaluated with contrast-enhanced chest CT.

To elucidate whether the morphological changes of the thoracic duct are observed in patients with liver cirrhosis and ascites, the thoracic duct was examined at magnetic resonance (MR) lymphography without contrast agent. In 7 healthy volunteers, the thoracic duct was clearly visualized as an intermittent or continuous straight line along the thoracic aorta (its mean diameter was 3.9 mm). In 20 liver cirrhosis without ascites, its mean diameter was 3.6 mm. In 6 liver cirrhosis with refractory ascites, the thoracic duct was visualized as straight or slightly tortuous and slender line (its mean diameter was 2.5 mm). On the other hand, 7 cases with ascites which respond well to the administration of diuretics showed tortuous and dilated thoracic duct (its mean diameter was 4.3 mm). In cases with refractory ascites, mean diameter of the thoracic duct was significantly reduced, compared with the cases without ascites and with ascites that respond well to the administration of diuretics. Thus, it was found that the morphological differences of the thoracic duct depend on the response to the diuretics in liver cirrhosis patients with ascites. To elucidate whether the morphological changes of the thoracic duct are observed in patients with liver cirrhosis and ascites, the thoracic duct was examined at magnetic resonance lymphography without contrast agent. In cases with refractory ascites, mean diameter of the thoracic duct was significantly reduced, compared with the cases without ascites and with ascites that respond well to the administration of diuretics.

Tracheobronchial stenosis is common in the thoracic surgery service, and iatrogenic injury of the airway after manipulation is not infrequent. When a digital thoracic drainage system came onto the market, many advantages were evident. A 24-year-old woman with critical right main bronchial stenosis underwent airway dilation that was complicated by a tear with a massive air leak, resulting in a total right pneumothorax. We employed a pleural drain connected to a digital thoracic drainage system. The drain was removed 2 days after successful resolution of the air leak. © The Author(s) 2015.

The results of managing of 129 injured persons, treated for injuries of the lower-thoracic and lumbar portions of vertebral column, are adduced. The puncture transcutaneous vertebroplasty was done in 58 patients, stabilizing systems "Sekstant" were installed in 15, the "Mantis" systems--in 13, rigid systems by the open method--in 43. The pain syndrome dynamics was estimated in of the patients in accordance to the visual analogue scale. Positive dynamics in a frame of the pain syndrome regression was noted postoperatively. Differentiated application of various methods of treatment in the patients, suffering nonstable compressional fracture of the lower-thoracic and lumbar portions of vertebral column, permits to reduce anesthesiological risk significantly, to improve the results of treatment, to reduce the patients rehabilitation duration.

Full Text Available Flattening of the preimplantation rod contour in the sagittal plane influences thoracic kyphosis (TK restoration in adolescent idiopathic scoliosis (AIS surgery. The effects of multilevel facetectomy and screw density on postoperative changes in spinal rod contour have not been documented. This study aimed to evaluate the effects of multilevel facetectomy and screw density on changes in spinal rod contour from before implantation to after surgical correction of thoracic curves in patients with AIS prospectively. The concave and convex rod shapes from patients with thoracic AIS (n = 49 were traced prior to insertion. Postoperative sagittal rod shape was determined by computed tomography. The angle of intersection of the tangents to the rod end points was measured. Multiple stepwise linear regression analysis was used to identify variables independently predictive of change in rod contour (Δθ. Average Δθ at the concave and convex side were 13.6° ± 7.5° and 4.3° ± 4.8°, respectively. The Δθ at the concave side was significantly greater than that of the convex side (P < 0.0001 and significantly correlated with Risser sign (P = 0.032, the preoperative main thoracic Cobb angle (P = 0.031, the preoperative TK angle (P = 0.012, and the number of facetectomy levels (P = 0.007. Furthermore, a Δθ at the concave side ≥14° significantly correlated with the postoperative TK angle (P = 0.003, the number of facetectomy levels (P = 0.021, and screw density at the concave side (P = 0.008. Rod deformation at the concave side suggests that corrective forces acting on that side are greater than on the convex side. Multilevel facetectomy and/or screw density at the concave side have positive effects on reducing the rod deformation that can lead to a loss of TK angle postoperatively.

To describe a novel hybrid technique to address two challenges in endovascular repair of chronic dissecting thoracic aortic aneurysm (dTAA): obtaining an adequate seal of the stent-graft in a half-moon-shaped fibrotic aortic lumen and preserving flow into the distal true and false lumens. The technique is demonstrated in a 52-year-old man who presented with progressive asymptomatic dilatation of the thoracic aorta 9 years after undergoing a Bentall procedure for a Stanford type A dissection followed by arch replacement and elephant trunk construction. Imaging at this admission showed a 6.8-cm dissecting aneurysm extending distally to ∼4 cm above the celiac trunk; the dissection included both common iliac arteries. The patient refused a thoracotomy, so a hybrid procedure was devised to resect the intimal flap via a median subxyphoid incision and transperitoneal approach through the lesser sac. Two overlapping Zenith TX-2 stent-grafts were deployed into the elephant trunk, terminating just above the surgically created "flow divider" at the level of the celiac trunk. Imaging showed adequate sealing at both ends of the stent-graft and a type II endoleak that persisted into follow-up, but the aneurysm diameter decreased to 6.4 cm, and there was unobstructed flow into the visceral, renal, and iliac arteries. In this case of chronic dTAA, open surgical removal of a segment of the dissection flap via a subxyphoid incision provided a distal landing zone for subsequent endoluminal repair, with exclusion of the aneurysm and preservation of antegrade flow in both true and false lumens.

With the first qualifying examination administered September 15, 2014, complex general surgical oncology (CGSO) is now a board-certified specialty. We aimed to assess the attitudes and perceptions of current and future surgical oncology fellows regarding the recently instituted Accreditation Council for Graduate Medical Education (ACGME) accreditation. A 29-question anonymous survey was distributed to fellows in surgical oncology fellowship programs and applicants interviewing at our fellowship program. There were 110 responses (79 fellows and 31 candidates). The response rate for the first- and second-year fellows was 66 %. Ninety-percent of the respondents were aware that completing an ACGME-accredited fellowship leads to board eligibility in CGSO. However, the majority (80 %) of the respondents stated that their decision to specialize in surgical oncology was not influenced by the ACGME accreditation. The fellows in training were concerned about the cost of the exam (90 %) and expressed anxiety in preparing for another board exam (83 %). However, the majority of the respondents believed that CGSO board certification will be helpful (79 %) in obtaining their future career goals. Interestingly, candidate fellows appeared more focused on a career in general complex surgical oncology (p = 0.004), highlighting the impact that fellowship training may have on organ-specific subspecialization. The majority of the surveyed surgical oncology fellows and candidates believe that obtaining board certification in CGSO is important and will help them pursue their career goals. However, the decision to specialize in surgical oncology does not appear to be motivated by ACGME accreditation or the new board certification.

The New 2016 European Society of Cardiology/European Association for Cardio-Thoracic Surgery Guidelines: Enough Guidance? Enough Evidence?

Castellá, Manuel

2018-04-01

For the first time, the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have joined forces to develop consensus guidelines for the management of atrial fibrillation (AF). One of the main issues is the integrated care of patients with AF, with emphasis on multidisciplinary teams of general physicians, cardiologists, stroke specialists and surgeons, together with the patient's involvement for better management of AF. These guidelines also help in the detection of risk factors and concomitant cardiovascular diseases, stroke prevention therapies, including anticoagulation and antiplatelet therapies after acute coronary episodes, major haemorrhages or strokes. In the field of ablation, surgery plays an important role as concomitant with other surgical procedures, and it should be considered in symptomatic patients with the highest level of evidence. Asymptomatic patients with mitral insufficiency should also be considered for combined mitral and AF surgery if they have new-onset AF. In patients with stand-alone AF, recommendations for minimally invasive ablation have an increased level of recommendation and should be considered as the same level as catheter ablation in patients with persistent or long-standing persistent AF or with paroxysmal AF who fail catheter ablation. Surgical occlusion or exclusion of the left atrial appendage may be considered for stroke prevention in patients with AF about to have surgery. Nevertheless, not enough is known to avoid long-term anticoagulation in patients at risk of stroke even if the left atrial appendage has been excluded. These Guidelines provide a full spectrum of recommendations on the management of patients with AF including prevention, treatment and complications based on the latest published evidence.

Clinical researches about the management and outcomes of ganglioneuroma and ganglioneuroblastoma-intermixed are limited. We report the surgical outcomes of ganglioneuroma and ganglioneuroblastoma-intermixed in a single institution. Ganglioneuroma and ganglioneuroblastoma-intermixed diagnosed and resected between May 2009 and May 2015 in a tertiary children's hospital were retrospectively reviewed. Patients' demographic data, INSS stage, surgical complications, residual tumor size and outcomes were collected. Thirty-four patients were included in the current study. All had localized tumors and were surgically managed. The overall acute complications rates were 8.8% (3/34) and none were fatal. Thirty-three of 34 patients had at least macroscopic tumor resection. Six patients had radiographically detected residual tumor after surgery, 25 none and 3 undocumented. Thirty-three (97.1%) patients were alive during a median follow-up of 36 months (range 1-82). In subgroup analysis, no significant difference regarding surgical complications and survival was found between ganglioneuroma and ganglioneuroblastoma-intermixed. Increased complete resection rates were observed in thoracic tumor compared with abdominal ones (p = 0.03). However, no significant difference (p = 0.089) regarding overall survival was found between patients with residual tumors and those without. Of the six patients with residual tumors, three showed complete resolution, two were unchanged and one died 3 years after initial surgery (the only death in this study). Ganglioneuroma and ganglioneuroblastoma-intermixed can be safely and effectively resected, the residual tumor seems not to influence overall survival.

Patients with diseases such as chronic obstructive pulmonary disease (COPD) need to improve their thorax mobility. Thoracic ROM is one of the simplest and most useful indexes to evaluate the respiratory function. In this paper, we have proposed the prototype of a simple thoracic ROM measurement system with real-time visual bio-feedback in the chest expansion test. In this system, the thoracic ROM is measured using a wire-type linear encoder whose wire is wrapped around the thorax. In this paper, firstly, the repeatability and reliability of measured thoracic ROM was confirmed as a first report of the developed prototype. Secondly, we analyzed the effect of the bio-feedback system on the respiratory function. The result of the experiment showed that it was easier to maintain a large and stable thoracic ROM during deep breathing by using the real-time visual biofeedback system of the thoracic ROM.

Objective: To observe effect of 125 Iodine sed on interstitial brachytherapy of patient with thoracic malignant tumor. Methods: 125 Iodine seed were inserted into the target tissue and permanent left there for brachytherapy in 6 cases of thoracic malignant tumors, which including lung cancer, Pancoast's tumour, mediastinal malignant schwannoma. Results: All cases were rehabilitated shortly after operation. The implanted lesions remained controlled now and in dead patients. No radiation-related and 125 Iodine seed-related complications occurred. Conclusion: Brachytherapy by implantation of 125 Iodine seeds of remained tumor tissue in patients with thoracic malignant tumor after operation has a satisfactory outcome. This therapy can control local recurrent of thoracic malignant tumor. But the results in long term should be studied further

There is extensive evidence that mobilization and manipulation of the thoracic spine is associated with improved outcomes in patients with neck pain. However, these evidence-based techniques are not always utilized. Successful knowledge translation programmes are needed to move the best available evidence to clinical practice. The purpose of the present research was to evaluate the effects of a structured knowledge translation programme on the frequency of manual therapy techniques performed by physical therapists on patients with neck pain. Prior to our intervention, we assessed physical therapists' use of thoracic spine intervention for the treatment of neck pain and their knowledge of the evidence. We delivered a multimodal knowledge translation programme and then reassessed their use and knowledge of the interventions. The majority of our physical therapists increased the use of thoracic spine techniques for their patients with neck pain. The increase was greater in those who used the techniques infrequently. Overall knowledge of the evidence appeared unchanged. Knowledge translation programmes are essential in ensuring clinical use of evidence-based practice. Our programme results, although on a small scale and not statistically significant, showed a positive trend toward increased thoracic spine manual therapy use for neck pain.

Introduction: Pneumothorax (PTX) occurs commonly in trauma patients and is confirmed by examination and radiography. Thoracic ultrasound (VIS) has been suggested as an alternative method for rapidly diagnosing PTX when X-ray is unavailable as in rural, military, or space flight settings; however, its accuracy and specificity are not known. Methods: We evaluated the accuracy of thoracic U/S detection of PTX compared to radiography in stable, emergency patients with a high suspicion of PTX at a Level-l trauma center over a 6-month period. Following University and NASA Institutional Review Board approval, informed consent was obtained from patients with penetrating or blunt chest trauma, or with a history consistent with PTX. Whenever possible, the presence or absence of the " lung sliding" sign or the "comet tail" artifact were determined by U/S in both hemithoraces by residents instructed in thoracic U/S before standard radiologic verification of PTX. Results were recorded on data sheets for comparison to standard radiography. Results: Thoracic VIS had a 94% sensitivity; two PTX could not be reliably diagnosed due to subcutaneous air; the true negative rate was 100%. In one patient, the VIS exam was positive while X ray did not confirm PTX; a follow-up film 1 hour later demonstrated a small PTX. The average time for bilateral thoracic VIS examination was 2 to 3 minutes. Conclusions: Thoracic ultrasound reliably diagnoses pneumothorax. Presence of the "lung sliding" sign conclusively excludes pneumothorax. Expansion of the FAST examination to include the thorax should be investigated.

A major pathogenic factor for catamenial pneumothorax is thoracic endometriosis. However, thoracic endometriosis-related pneumothorax (TERP) can develop as either catamenial or non-catamenial pneumothorax (CP). Therefore, the aim of this study was to elucidate the clinical differences between catamenial and non-catamenial TERP. The clinical and pathological data in female patients who underwent video-assisted thoracoscopic surgery at the Pneumothorax Research Center during an 8-year period were retrospectively reviewed. This study included 150 female patients with surgico-pathologically confirmed TERP. The subjects were divided into two groups, those having all of the pneumothorax episodes in the catamenial period (CP group) and those who did not (non-CP group). We compared the clinical characteristics and surgico-pathological findings between these two groups. Of the 150 TERP patients, 55 (36.7%) were classified in the CP group, and 95 (63.3%) in the non-CP group. In regard to the locations of endometriosis, all TERP patients had diaphragmatic endometriosis, while pleural implantation was recognized in 34 of the 55 (61.8%) patients in the CP group and 42 of the 95 (44.2%) patients in the non-CP group (P pneumothorax episodes. © 2015 Asian Pacific Society of Respirology.

Patients with thoracic aorta injuries (TAI) present a unique challenge. The purpose of this study was to review the outcomes of thoracic endovascular aortic repair (TEVAR) in patients with TAI. A retrospective chart review of all patients admitted for TEVAR for trauma was performed. In a 5-year period, 19 patients (6 women and 13 men; average age, 42 y) were admitted to our trauma center with TAI. Mechanism of injury was a motor vehicle crash in 12 patients, motorcycle crash in 2 patients, automobile-pedestrian accident in 2 patients, 1 fall, 1 crush injury, and 1 stab wound to the back. A thoracic endograft was used in 6 patients and proximal aortic cuffs were used in 13 patients (68%). One patient (5%) died. There were no strokes, myocardial infarctions, paraplegia, or renal failure. TEVAR for TAI appears to be a safe option for patients with multiple injuries. TEVAR in young patients is still controversial because long-term endograft behavior is unknown. Copyright © 2012 Elsevier Inc. All rights reserved.

Cardiothoracic surgical experience in Ghana.

Ghana is one of the few low-to-middle-income countries in sub-Saharan Africa able to consistently sustain a cardiothoracic program with locally trained staff for more than two decades. Cardiothoracic surgery practice in Ghana started in 1964 but faltered from a combination of political and the economic problems. In 1989, Dr. Kwabena Frimpong-Boateng, a Ghanaian cardiothoracic surgeon trained in Hannover, rekindled interest in cardiothoracic surgery and in establishing a National Cardiothoracic Centre. His vision and leadership has brought cardiothoracic surgery practice in Ghana to its current high level. As a result, the medical landscape of what is achievable locally in both pediatric and adult patients has changed substantially: outbound medical travel that used to be common among Ghanaian cardiovascular patients has been reduced drastically. Ghana's National Cardiothoracic Center (NCTC), the only tertiary center in the country for cardiothoracic surgical pathology manages all such patients that were previously referred abroad. The NCTC has become a medical/surgical hub in the West African sub-region providing service, training, and research opportunities to neighboring countries. The Centre is accredited by the West African College of Surgeons as a center of excellence for training specialists in cardiothoracic surgery. Expectedly, practicing cardiothoracic surgery in such a resource-poor setting has peculiar challenges. This review focuses on the history, practice, successes, and challenges of cardiovascular and thoracic surgery in Ghana.

The damage control surgery came up with the philosophy of applying essential maneuvers to control bleeding and abdominal contamination in trauma patients who are within the limits of their physiological reserves. This concept was extended to thoracic injuries, where relatively simple maneuvers can shorten operative time of in extremis patients. This article aims to revise the various damage control techniques in thoracic organs that must be known to the surgeon engaged in emergency care. RESUMO A cirurgia de controle de danos surgiu com a filosofia de se aplicar manobras essenciais para controle de sangramento e contaminação abdominal, em doentes traumatizados, nos limites de suas reservas fisiológicas. Este conceito se estendeu para as lesões torácicas, onde manobras relativamente simples, podem abreviar o tempo operatório de doentes in extremis. Este artigo tem como objetivo, revisar as diversas técnicas de controle de dano em órgãos torácicos, que devem ser de conhecimento do cirurgião que atua na emergência.

Objectives  The definition of spontaneous pneumothorax is accumulation of air in the pleural space, resulting in dyspnea or chest pain. Unlike primary spontaneous pneumothorax, secondary pneumothorax can be a life-threatening condition and spontaneous healing rate is uncommon. Although surgery is the most effective treatment modality for pneumothorax, surgical management and timing is difficult where there is underlying lung disease and/or medical comorbidities. Prolonged air leakage increases the morbidity and mortality in thoracic surgery. We hypothesized that duration of air leakage before operation may lead to increase in complications. Methods  This study is a retrospective review of 155 consecutive patients with air leakage who underwent bullectomy for secondary spontaneous pneumothorax from January 2005 to July 2013. The patients were divided according to the duration of preoperative air leakage. The patients were followed-up until the time of last visit or death. Postoperative morbidity and mortality were assessed and the risk factors for complications were analyzed. Results  The median age was 65 years (range, 52-88) with male predominance (96.13%). The median duration of preoperative air leakage was 6 days (range, 1-30). The median surgery time was 90 minutes (range, 25-300) and median hospital stay after operation was 7 days (range, 3-75). Postoperative complications occurred in 38 patients (24.52%) and postoperative recurrence was shown to have occurred in 8 patients (5.16%). With multivariate analysis, risk factors for postoperative complications were: underlying interstitial lung disease and air leakage > 5 days before operation. Conclusion  Persistent air leakage was a major surgical indication for pneumothorax. Early surgical treatment reduced postoperative complications for secondary spontaneous pneumothorax.

The objective of this study was to collect integrated data from nationwide hospitals using a web-based national database system to build up our own risk model for the outcome from thoracic aortic surgery. The Japan Adult Cardiovascular Surgery Database was used; this involved approximately 180 hospitals throughout Japan through a web-based data entry system. Variables and definitions are almost identical to the STS National Database. After data cleanup, 4707 records were analyzed from 97 hospitals (between January 1, 2000, and December 31, 2005). Mean age was 66.5 years. Preoperatively, the incidence of chronic lung disease was 11%, renal failure was 9%, and rupture or malperfusion was 10%. The incidence of the location along the aorta requiring replacement surgery (including overlapping areas) was: aortic root, 10%; ascending aorta, 47%; aortic arch, 44%; distal arch, 21%; descending aorta, 27%; and thoracoabdominal aorta, 8%. Raw 30-day and 30-day operative mortality rates were 6.7% and 8.6%, respectively. Postoperative incidence of permanent stroke was 6.1%, and renal failure requiring dialysis was 6.7%. OR for 30-day operative mortality was as follows: emergency or salvage, 3.7; creatinine >3.0 mg/dL, 3.0; and unexpected coronary artery bypass graft, 2.6. As a performance metric of the risk model, C-index of 30-day and 30-day operative mortality was 0.79 and 0.78, respectively. This is the first report of risk stratification on thoracic aortic surgery using a nationwide surgical database. Although condition of these patients undergoing thoracic aortic surgery was much more serious than other procedures, the result of this series was excellent.

The extrapleural space is external to the parietal pleura in the thorax. The structures within and adjacent to this region include the fat pad, endothoracic fascia, intercostal muscles, connective tissue, nerves, vessels, and ribs. Further, the space is divided into the inner and outer thoracic wall by the innermost intercostal muscle. Extrapleural lesions in the inner thoracic wall are classified as air-containing lesions, fat-containing lesions, and soft tissue-containing lesions according on their main component. Air-containing lesions include extrapleural air from direct chest trauma and extrapleural extension from pneumomediastinum. Prominent extrapleural fat is seen in decreased lung volume conditions, and can also be seen in normal individuals. Soft tissue-containing lesions include extrapleural extensions from a pleural or chest wall infection as well as tumors and extrapleural hematoma. We classify extrapleural lesions in the inner thoracic wall and illustrate their imaging findings

Full Text Available Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

Thoracic fat has been associated with an increased risk of coronary artery disease (CAD). As endothelium-dependent vasoreactivity is a surrogate of cardiovascular events and is impaired early in atherosclerosis, we aimed at assessing the possible relationship between thoracic fat volume (TFV) and endothelium-dependent coronary vasomotion. Fifty healthy volunteers without known CAD or major cardiovascular risk factors (CRFs) prospectively underwent a {sup 82}Rb cardiac PET/CT to quantify myocardial blood flow (MBF) at rest, and MBF response to cold pressor testing (CPT-MBF) and adenosine (i.e., stress-MBF). TFV was measured by a 2D volumetric CT method and common laboratory blood tests (glucose and insulin levels, HOMA-IR, cholesterol, triglyceride, hsCRP) were performed. Relationships between CPT-MBF, TFV and other CRFs were assessed using non-parametric Spearman rank correlation testing and multivariate linear regression analysis. All of the 50 participants (58 ± 10y) had normal stress-MBF (2.7 ± 0.6 mL/min/g; 95 % CI: 2.6-2.9) and myocardial flow reserve (2.8 ± 0.8; 95 % CI: 2.6-3.0) excluding underlying CAD. Univariate analysis revealed a significant inverse relation between absolute CPT-MBF and sex (ρ = -0.47, p = 0.0006), triglyceride (ρ = -0.32, p = 0.024) and insulin levels (ρ = -0.43, p = 0.0024), HOMA-IR (ρ = -0.39, p = 0.007), BMI (ρ = -0.51, p = 0.0002) and TFV (ρ = -0.52, p = 0.0001). MBF response to adenosine was also correlated with TFV (ρ = -0.32, p = 0.026). On multivariate analysis, TFV emerged as the only significant predictor of MBF response to CPT (p = 0.014). TFV is significantly correlated with endothelium-dependent and -independent coronary vasomotion. High TF burden might negatively influence MBF response to CPT and to adenosine stress, even in persons without CAD, suggesting a link between thoracic fat and future cardiovascular events. (orig.)

Moore Ernest E

2009-02-01

Full Text Available Abstract Background Pyogenic spondylodiscitis represents a potentially life-threatening condition. Due to the low incidence, evidence-based surgical recommendations in the literature are equivocal, and the treatment modalities remain controversial. Case presentation A 59 year-old patient presented with a history of thoracic spondylodiscitis resistant to antibiotic treatment for 6 weeks, progressive severe back pain, and a new onset of bilateral lower extremity weakness. Clinically, the patient showed a deteriorating spastic paraparesis of her lower extremities. An emergent MRI revealed a kyphotic wedge compression fracture at T7/T8 with significant spinal cord compression, paravertebral and epidural abscess, and signs of myelopathy. The patient underwent surgical debridement with stabilization of the anterior column from T6–T9 using an expandable titanium cage, autologous bone graft, and an anterolateral locking plate. The patient recovered well under adjunctive antibiotic treatment. She presented again to the emergency department 6 months later, secondary to a repeat fall, with acute paraplegia of the lower extremities and radiographic evidence of failure of fixation of the anterior T-spine. She underwent antero-posterior revision fixation with hardware removal, correction of kyphotic malunion, evacuation of a recurrent epidural abscess, decompression of the spinal canal, and 360° fusion from T2–T11. Despite the successful salvage procedure, the patient deteriorated in the postoperative phase, when she developed multiple complications including pneumonia, acute respiratory distress syndrome, bacterial meningitis, abdominal compartment syndrome, followed by septic shock with multiple organ failure and a lethal outcome within two weeks after revision surgery. Conclusion This catastrophic example of a lethal outcome secondary to failure of anterior column fixation for pyogenic thoracic spondylodiscitis underlines the notion that surgical

Thoracic empyema and pectoral abscess resulting from attempting suicide by injection of benzene in the pleural cavity

Directory of Open Access Journals (Sweden)

Sjaak Pouwels

Full Text Available Background: Exposure to hydrocarbon compounds, such as benzene may cause injury to several organ systems. It occurs accidentally or intentionally by ingestion, inhalation, cutaneous exposure and either subcutaneous injection or intravenous injection. We report a patient who injected benzene into the left hemithorax and secondly attempted to commit suicide with paracetamol. Case presentation: A 52-year old man was admitted in the hospital because of an attempted suicide with an injection of benzene in the left hemithorax and ingestion of 50 tablets of 500 mg paracetamol. He developed a hydro-tensionpneumothorax due to inflammatory pleural effusion as a reaction to intrathoracic benzene. Therefore a chest-tube was inserted. A few days later he developed an empyema in the left lung and secondly a pectoral abscess, which required surgical debridement. After surgery, recovered fully and after 23 days of hospitalisation he was discharged to a psychiatric care facility. Conclusion: Hydrocarbon poisoning is either accidentally or intentionally and leads to thoracic pathology in rare cases. The most affected organ system is the respiratory system, and the cytotoxic effects of hydrocarbons can manifest as respiratory failure, pneumonitis and even acute respiratory distress syndrome (ARDS.

Purpose: To evaluate the effectiveness and safety of endovascular treatment of various descending thoracic aortic pathologies with covered stent-grafts as an alternative to open surgery. Methods: Among 16 patients (5 type B dissections, 5 contained ruptures, 3 aneurysms of the descending aorta, 1 thoraco-abdominal aneurysm, 1 mural thrombosis, 1 patch aneurysm) treated between November 1997 and November 2000, eight patients received Talent TM stent-grafts and another 8 patients underwent a Gore-TAG TM stent-graft implantation. A clinical follow-up and control CT scans were obtained after the procedure and then at six-month intervals. Results: Deployment of the stent-grafts was technically successful in all cases. Sufficient aortic reconstruction was achieved in all but one patient who needed surgical treatment. One patient died two days after the procedure from aortic rupture due to retrograde type A dissection. Another patient died 19 months after the procedure from an unknown cause. There was no occurrence of distal embolization, paralysis or infection. During follow-up, all patients remained free from recurrence or late complications of their disease. Conclusion: Endoluminal treatment of thoracic aortic pathologies with covered stent-grafts appears to be a safe and feasible method with at least mid-term efficacy. (orig.) [de

As part of the peer review process for the European Journal of Cardio-Thoracic Surgery (EJCTS) and the Interactive CardioVascular and Thoracic Surgery (ICVTS), a statistician reviews any manuscript that includes a statistical analysis. To facilitate authors considering submitting a manuscript and to make it clearer about the expectations of the statistical reviewers, we present up-to-date guidelines for authors on statistical and data reporting specifically in these journals. The number of statistical methods used in the cardiothoracic literature is vast, as are the ways in which data are presented. Therefore, we narrow the scope of these guidelines to cover the most common applications submitted to the EJCTS and ICVTS, focusing in particular on those that the statistical reviewers most frequently comment on. © The Author 2015.

The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as neurosurgery and cardiovascular surgery, it has rarely been explored in thoracic surgery. Our objective was to discuss the possible applications of this technology in thoracic surgery, through the reporting of three cases. RESUMO O conceito de sala híbrida traduz a união de um aparato cirúrgico de alta complexidade com recursos radiológicos de última geração (ultrassom, TC, radioscopia e/ou ressonância magnética), visando a realização de procedimentos minimamente invasivos e altamente eficazes. Apesar de bem estabelecido em outras especialidades, como neurocirurgia e cirurgia cardiovascular, o uso da sala hibrida ainda é pouco explorado na cirurgia torácica. Nosso objetivo foi discutir as aplicações e as possibilidades abertas por essa tecnologia na cirurgia torácica através do relato de três casos.

Effective use of postoperative incentive spirometry improves patient outcomes but is limited by pain after thoracic and upper abdominal surgery. Thoracic epidurals are frequently used to provide analgesia and attenuate postoperative pulmonary dysfunction. We hypothesized that, in patients with thoracic epidurals for thoracic and abdominal surgery, high pain scores would be associated with poorer incentive spirometry performance, even when accounting for other variables. Retrospective study of 468 patients who underwent upper abdominal or thoracic surgery using postoperative thoracic epidural analgesia between June 1, 2009, and August 31, 2013, at a single tertiary academic center. The association between incentive spirometry performance and pain was assessed as the primary outcome. Other independent predictors of incentive spirometry performance were also identified. Postoperative incentive spirometry performance was found to be inversely proportional to pain score, which correlated significantly stronger with deep breathing pain compared with pain at rest (-0.33 vs -0.14 on postoperative day 1; -0.23 vs -0.12 on postoperative day 2). Pain with deep breathing was independently associated with poorer incentive spirometry performance in the multivariable linear regression model (P spirometry performance could be used as another indicator of thoracic epidural efficacy. This may be particularly useful in patients reporting high pain scores postoperatively.

The Thoracic Surgery Foundation for Research and Education (TSFRE) was formed in 1991 with the primary goals of generating new knowledge and nurturing the development of surgeon-scientists. The purpose of this article is to determine how effective the TSFRE has been in achieving these goals. A survey instrument was sent electronically to all former and current TSFRE research award recipients. Major themes included the benefits on TSFRE award recipients with respect to career choices of thoracic surgery, progress toward research independence, and the ability to leverage TSFRE funds to more substantive National Institutes of Health (NIH) awards. Success rates for NIH funding were confirmed using NIH Research Portfolio Online Reporting Tools. The total completed survey response rate was 70% (75/107). The response rates for each group were as follows: resident 74% (28/38), faculty 85% (29/34), Braunwald 50% (9/18), and TSFRE/NIH K-award 65% (11/17). The funding rate for all grants was 14% (90/619). For resident research awardees, 81% (34/42) are cardiothoracic surgeons or are thoracic surgery residents. The conversion rate for existing TSFRE/NIH co-sponsored K-awards to R01 grants is 40% at 5 years compared with a 20% K to R conversion rate for all NIH K-award recipients. K to R conversion rates for junior faculty grant awardees without a prior K-award is 44%, which is much higher than NIH rates for all new investigator R01 awards. The return on investment for TSFRE funding for surgeon-scientists is resoundingly positive with respect to promoting careers in cardiothoracic surgery and to obtaining subsequent NIH funding for thoracic surgeon investigators.

Safari, Saeed; Radfar, Fatemeh; Baratloo, Alireza

2018-05-01

This study aimed to compare the diagnostic accuracy of NEXUS chest and Thoracic Injury Rule out criteria (TIRC) models in predicting the risk of intra-thoracic injuries following blunt multiple trauma. In this diagnostic accuracy study, using the 2 mentioned models, blunt multiple trauma patients over the age of 15 years presenting to emergency department were screened regarding the presence of intra-thoracic injuries that are detectable via chest x-ray and screening performance characteristics of the models were compared. In this study, 3118 patients with the mean (SD) age of 37.4 (16.9) years were studied (57.4% male). Based on TIRC and NEXUS chest, respectively, 1340 (43%) and 1417 (45.4%) patients were deemed in need of radiography performance. Sensitivity, specificity, and positive and negative predictive values of TIRC were 98.95%, 62.70%, 21.19% and 99.83%. These values were 98.61%, 59.94%, 19.97% and 99.76%, for NEXUS chest, respectively. Accuracy of TIRC and NEXUS chest models were 66.04 (95% CI: 64.34-67.70) and 63.50 (95% CI: 61.78-65.19), respectively. TIRC and NEXUS chest models have proper and similar sensitivity in prediction of blunt traumatic intra-thoracic injuries that are detectable via chest x-ray. However, TIRC had a significantly higher specificity in this regard. Copyright © 2018 Elsevier Ltd. All rights reserved.

Thoracic aortic emergencies account for 10% of thoracic-related admissions in the United States and remain associated with high morbidity and mortality rates. Open repair has declined owing to the emergence of thoracic endovascular aortic repair (TEVAR), but data on emergency TEVAR use for acute aortic pathology remain limited. We therefore reviewed our experience. We retrospectively evaluated emergency descending thoracic aortic endovascular interventions performed at a single academic level 1 trauma center between January 2005 and August 2013 including all cases of traumatic aortic injury, ruptured descending thoracic aneurysm, penetrating atherosclerotic ulcer, aortoenteric fistula, and acute complicated type B dissection. Demographics, clinical data, and outcomes were extracted. Stepwise logistic regression was used to identify independent risk factors for death. During the study period, 51 patients underwent TEVAR; 22 cases (43.1%) were performed emergently (11 patients [50.0%] traumatic aortic injury; 4 [18.2%] ruptured descending thoracic aneurysm; 4 [18.2%] complicated type B dissection; 2 [9.1%] penetrating aortic ulcer; and 1 [4.5%] aortoenteric fistula). Overall, 72.7% (n = 16) were male with a mean age of 54.8 ± 15.9 years. Nineteen patients (86.4%) required only a single TEVAR procedure, whereas 2 (9.1%) required additional endovascular therapy, and 1 (4.5%) open thoracotomy. Four traumatic aortic injury patients required exploratory laparotomy for concomitant intra-abdominal injuries. During a mean hospital length of stay of 18.9 days (range, 1 to 76 days), 3 patients (13.6%) developed major complications. In-hospital mortality was 27.2%, consisting of 6 deaths from traumatic brain injury (1); exsanguination in the operating room before repair could be achieved (2); bowel ischemia (1) and multisystem organ failure (1); and family withdrawal of care (1). A stepwise logistic regression model identified 24-hour packed red blood cell requirements ≥4

Scoliosis deformity has been linked with deleterious changes in the thoracic cavity that affect pulmonary function. The causal relationship between spinal deformity and pulmonary function has yet to be fully defined. It has been hypothesized that deformity correction improves pulmonary function by restoring both respiratory muscle efficiency and increasing the space available to the lungs. This research aims to correlate pulmonary function and thoracic volume before and after scoliosis correction. Retrospective correlational analysis between thoracic volume modeling from plain x-rays and pulmonary function tests was conducted. Adolescent idiopathic scoliosis patients enrolled in a multicenter database were sorted by pre-operative Total Lung Capacities (TLC) % predicted values from their Pulmonary Function Tests (PFT). Ten patients with the best and ten patients with the worst TLC values were included. Modeled thoracic volume and TLC values were compared before and 2 years after surgery. Scoliosis correction resulted in an increase in the thoracic volume for patients with the worst initial TLCs (11.7%) and those with the best initial TLCs (12.5%). The adolescents with the most severe pulmonary restriction prior to surgery strongly correlated with post-operative change in total lung capacity and thoracic volume (r 2  = 0.839; p volume in this group was 373.1 cm 3 (11.7%) which correlated with a 21.2% improvement in TLC. Scoliosis correction in adolescents was found to increase thoracic volume and is strongly correlated with improved TLC in cases with severe restrictive pulmonary function, but no correlation was found in cases with normal pulmonary function. © 2016 Orthopaedic Research Society.

Redden, Mark D; Chin, Tze Yang; van Driel, Mieke L

2017-03-17

Empyema refers to pus in the pleural space, commonly due to adjacent pneumonia, chest wall injury, or a complication of thoracic surgery. A range of therapeutic options are available for its management, ranging from percutaneous aspiration and intercostal drainage to video-assisted thoracoscopic surgery (VATS) or thoracotomy drainage. Intrapleural fibrinolytics may also be administered following intercostal drain insertion to facilitate pleural drainage. There is currently a lack of consensus regarding optimal treatment. To assess the effectiveness and safety of surgical versus non-surgical treatments for complicated parapneumonic effusion or pleural empyema. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 9), MEDLINE (Ebscohost) (1946 to July week 3 2013, July 2015 to October 2016) and MEDLINE (Ovid) (1 May 2013 to July week 1 2015), Embase (2010 to October 2016), CINAHL (1981 to October 2016) and LILACS (1982 to October 2016) on 20 October 2016. We searched ClinicalTrials.gov and WHO International Clinical Trials Registry Platform for ongoing studies (December 2016). Randomised controlled trials that compared a surgical with a non-surgical method of management for all age groups with pleural empyema. Two review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked the data for accuracy. We contacted trial authors for additional information. We assessed the quality of the evidence using the GRADE approach. We included eight randomised controlled trials with a total of 391 participants. Six trials focused on children and two on adults. Trials compared tube thoracostomy drainage (non-surgical), with or without intrapleural fibrinolytics, to either VATS or thoracotomy (surgical) for the management of pleural empyema. Assessment of risk of bias for the included studies was generally unclear for selection and blinding but low for attrition and reporting bias. Data analyses compared

Thoracic spine manipulation is commonly used by physical therapists for the management of patients with upper quarter pain syndromes. The theoretical construct for using thoracic manipulation for upper quarter conditions is a mainstay of a regional interdependence (RI) approach. The RI concept is likely much more complex and is perhaps driven by a neurophysiological response including those related to peripheral, spinal cord and supraspinal mechanisms. Recent evidence suggests that thoracic spine manipulation results in neurophysiological changes, which may lead to improved pain and outcomes in individuals with musculoskeletal disorders. The intent of this narrative review is to describe the research supporting the RI concept and its application to the treatment of individuals with neck and/or shoulder pain. Treatment utilizing both thrust and non-thrust thoracic manipulation has been shown to result in improvements in pain, range of motion and disability in patients with upper quarter conditions. Research has yet to determine optimal dosage, techniques or patient populations to which the RI approach should be applied; however, emerging evidence supporting a neurophysiological effect for thoracic spine manipulation may negate the need to fully answer this question. Certainly, there is a need for further research examining both the clinical efficacy and effectiveness of manual therapy interventions utilized in the RI model as well as the neurophysiological effects resulting from this intervention.

To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm) and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55%) men and 9 (45%) women. Nine (45%) patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85%) patients and 3 (15%) were managed conservatively. End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury. Patients with end stage renal disease who sustain inadvertent arterial puncture during cannulation for

Non-surgical removal of foreign bodies were successfully done in 7 cases in the Department of Radiology. Seoul National University Hospital from june 1983 to April 1987. In four cases of foreign body in cardiovascular system, a broken catheter, which located in descending thoracic aorta, was removed using loop-snare technique, and broken catheter or disconnected arterial sheaths, which located in right common iliac artery or right femoral artery, were removed using basket techniques in 3 cases. And in two cases of foreign body in urinary system, an internal stent, which located in ileal conduit, was removed using loop-snare technique. And the other was displaced internal stent which was removed using loop snare technique via percutaneous nephrostomy. And a broken limb of T-tube in biliary system was removed by basket technique via T-tube tract. There were no complication which was related with those retrieval procedures.

Reports documenting the use of extracorporeal membrane oxygenation (ECMO) after blunt thoracic trauma are scarce. We used a large, multicenter database to examine outcomes when ECMO was used in treating patients with blunt thoracic trauma. We performed a retrospective analysis of ECMO patients in the Extracorporeal Life Support Organization database between 1998 and 2014. The diagnostic code for blunt pulmonary contusion (861.21, DRG International Classification of Diseases-9th Rev.) was used to identify patients treated with ECMO after blunt thoracic trauma. Variations of pre-ECMO respiratory support were also evaluated. The primary outcome was survival to discharge; the secondary outcome was hemorrhagic complication associated with ECMO. Eighty-five patients met inclusion criteria. The mean ± SEM age of the cohort was 28.9 ± 1.1 years; 71 (83.5%) were male. The mean ± SEM pre-ECMO PaO2/FIO2 ratio was 59.7 ± 3.5, and the mean ± SEM pre-ECMO length of ventilation was 94.7 ± 13.2 hours. Pre-ECMO support included inhaled nitric oxide (15 patients, 17.6%), high-frequency oscillation (10, 11.8%), and vasopressor agents (57, 67.1%). The mean ± SEM duration of ECMO was 207.4 ± 23.8 hours, and 63 patients (74.1%) were treated with venovenous ECMO. Thirty-two patients (37.6%) underwent invasive procedures before ECMO, and 12 patients (14.1%) underwent invasive procedures while on ECMO. Hemorrhagic complications occurred in 25 cases (29.4%), including 12 patients (14.1%) with surgical site bleeding and 16 (18.8%) with cannula site bleeding (6 patients had both). The rate of survival to discharge was 74.1%. Multivariate analysis showed that shorter duration of ECMO and the use of venovenous ECMO predicted survival. Outcomes after the use of ECMO in blunt thoracic trauma can be favorable. Some trauma patients are appropriate candidates for this therapy. Further study may discern which subpopulations of trauma patients will benefit most from ECMO. Therapeutic

Full Text Available Abstract Background Patients undergoing major elective or urgent surgery are at high risk of death or significant morbidity. Measures to reduce this morbidity and mortality include pre-operative optimisation and use of higher levels of dependency care after surgery. We propose a pragmatic multi-centre randomised controlled trial of level of dependency and pre-operative fluid therapy in high-risk surgical patients undergoing major elective surgery. Methods/Design A multi-centre randomised controlled trial with a 2 * 2 factorial design. The first randomisation is to pre-operative fluid therapy or standard regimen and the second randomisation is to routine intensive care versus high dependency care during the early post-operative period. We intend to recruit 204 patients undergoing major elective and urgent abdominal and thoraco-abdominal surgery who fulfil high-risk surgical criteria. The primary outcome for the comparison of level of care is cost-effectiveness at six months and for the comparison of fluid optimisation is the number of hospital days after surgery. Discussion We believe that the results of this study will be invaluable in determining the future care and clinical resource utilisation for this group of patients and thus will have a major impact on clinical practice.

Objective: To discuss the noticeable problems in the radiological diagnosis of thoracic sarcoidosis through retrospective analysis of misdiagnosis. Methods: Imaging examinations of 32 misdiagnosed cases with thoracic sarcoidosis including chest radiography, CT, and their clinical data were reviewed. The final diagnosis was made by pathology (9 cases) and clinical therapy (23 cases). Results: Enlarged thoracic lymph nodes were detected in all cases. 23 of them presented mediastinal lymph node enlargement associated with bilateral hilar lymph node enlargement, 5 of them had mediastinal lymph node enlargement and unilateral hilar lymph node enlargement, and 4 of them had mediastinal lymph node enlargement without hilar lymph node enlargement. In these cases, 24 had pulmonary abnormalities. 19 of them showed multiple pulmonary nodes, 4 of them had patchy pulmonary shadows, and another 1 had pulmonary fibrosis. Pleural lesions included 2 hydrothorax and 1 multiple pleural nodes, and all of pleural lesions were associated with multiple pulmonary nodes. Conclusion: When the radiological findings of thoracic sarcoidosis are atypical, the diagnosis is difficult and must combine with the clinical findings, or the outcome of the treatment

Full Text Available Purpose: The cervicothoracic junction (CTJ represents a transition from the semirigid thoracic spine to the mobile subaxial cervical spine. Pathologic lesions are prone to kyphotic deformity. The aim of this study was to review our experience with surgical stabilization of metastatic lesions affecting the CTJ (C7-T2. Materials and Methods: We reviewed all surgical stabilizations of metastatic spine lesions over the preceding 4 years in our institution. A total of 14 patients with CTJ lesions were identified. Case notes and radiology were reviewed to determine the presentation, outcomes, and specific complications. Results: The mean survival was 405 days (standard deviation [s.d.] 352. 8/14 died at a mean time from surgery of 193 days (s.d. 306. Most cases were a result of either lung or breast primary tumors. Half were stabilized with an anterior only approach and two had staged anterior-posterior. There were no cases of neurologic deterioration in this cohort as a result of surgery. There were two cases of deep surgical site infection and two documented cases of pulmonary embolus. There were no reported construct failures over the follow-up period. Conclusion: Patients with cervicothoracic metastatic lesions can be treated with either anterior or posterior approaches or a combination after considering each individual′s potential instability and disease burden.

Full Text Available Background The identification of independent factors affecting the loss of lumbar lordosis can facilitate programmed surgery in adolescent idiopathic scoliosis (AIS patients especially with considering the importance of sagittal characteristics. Objectives This study aimed to investigate the factors affecting the amount of the loss of lumbar lordosis in surgical treatment of the patients with AIS using segmental instrumentation. Methods In this study which was conducted in three years, 91 AIS patients who underwent segmental instrumentation were studied and 63 patients remained in the study according to the inclusion criteria. All patients’ information was recorded on admission in separate forms and radiography results were coded and archived before the surgery for more evaluation. All patients were subject to standing whole spine radiograph again 12 months after the surgery. Ultimately, the information was put into predetermined forms and was used for a statistical analysis after the completion of forms. Results The mean age of the patients was 15.62 ± 3.09 years. The mean preoperative lumbar lordosis was 45.25 ± 12.17 degrees and the mean preoperative thoracic kyphosis was 41.54 ± 16.31 degrees. The mean postoperative lumbar lordosis was 34.37 ± 10.26 degrees. The mean postoperative thoracic kyphosis was obtained 26.56 ± 9.17. The mean surgical correction of thoracic kyphotic deformity and lumbar lordosis were correlated with each other with the correlation coefficient of 0.71 (P < 0.001. Men have more (16.62 ± 8.74 loss of lumbar lordosis than women (10.05 ± 8.53 (P < 0.001. There was not any significant correlation between the type (hook/hybrid of the instrumentation with the loss of lumbar lordosis (P = 0.07, P = 0.41. Conclusions Considering the findings of this study, the most important factor affecting the amount of post-operative loss of lumbar lordosis in segmental instrumentation in AIS patients is the amount of the
