    Tracheoesophageal fistula (TEF) is a relatively rare congenital anomaly. Surgical intervention is required to establish esophageal continuity and prevent aspiration and overdistension of the stomach. Since the first successful report of thoracoscopic TEF repair in 2000, the minimally invasive approach has become increasingly utilized. The main advantages of the thoracoscopic technique include avoidance of a thoracotomy, improved cosmesis, and superior visualization of the anatomy and fistula afforded by the laparoscope׳s magnification.

    2012-01-01

    A tracheoesophageal fistula is an abnormal con- nection between the esophagus and the trachea and is a rarely seen pathology. The absence of the fetal stomach or visualization of the fetal stom- ach smaller than normal by ultrasound in early gestation, and detection of polyhydramnios in third trimester are the most valuable signs in ul- trasonographic examination. In addition to this, depending on the type of the anomaly, blind pouch sign of the esophagus can be detected at the medi- astinum ...

    Scimitar syndrome is a rare, combined abnormality of bronchopulmonary development and pulmonary vascular development characterized by an anomalous pulmonary venous return to the inferior vena cava. Although the scimitar syndrome has been associated with many anomalies, a tracheoesophageal fistula (TEF), especially from H-type, is extremely rare and only a few cases have been reported without detailed descriptions. Herein we report a rare case of scimitar syndrome with H-type TEF and multiple anomalies in a newborn infant, with a special emphasis on the imaging features associated with the radiologic diagnosis using an electrocardiography-gated computed tomography.

  4. A spectrum of bronchopulmonary anomalies associated with tracheoesophageal malformations

    International Nuclear Information System (INIS)

    The combination of tracheoesophageal and pulmonary malformations is unusual and reportedly carries a high mortality. We have observed six patients with esophageal atresia and tracheoesophageal fistula and one with a bronchoesophageal fistula who had associated bronchopulmonary anomalies ranging from lobar hypoplasia and agenesis to unilateral pulmonary hypoplasia or agenesis. All of the pulmonary malformations were right-sided. Vertebral or rib anomalies were present in five patients, congenital heart disease in two, imperforate anus in one and one patient had radial aplasia and Pierre Robin syndrome. The bronchopulmonary anomalies complicated the surgical care of tracheoesophageal malformations and required radiologic differentiation from aspiration pneumonia and atelectasis. Six of the seven patients survived. Mortality and morbidity were related to complications and associated cardiac anomalies as well as severity of the lung anomaly. (orig.)

    Full Text Available Paracoccidioidomycosis is a systemic fungal disease caused byParacoccidioides brasiliensis, agent geographically distributed to certainareas of Central and South America. The infection by P. brasiliensis hasbeen reported from north Mexico to south Argentina. Paracoccidioidomycosispresents similar clinical findings of many other diseases whatever in acute or chronic scenarios. Chronic pulmonary paracoccidioidomycosis is frequentlymisdiagnosed as malignancy or tuberculosis. The authors present a caseof a 57 year-old man admitted to the hospital due to a chronic consumptivesyndrome. He underwent anti-tuberculous treatment with rifampin, isoniazid andpyrazinamide 1 year ago without resolution of the simptoms. During the clinicalinvestigation, pulmonary paracoccidioidomycosis with tracheoesophagealfistula was diagnosed. The systemic infection was treated with deoxicolate Bamphotericin followed by sulfametoxazole and trimetoprin due to acute renalfunction impairment. The fistula was endoscopically treated; inittialy with theprotection of left main bronchus with a tracheal prosthesis followed by theesophageal fistula’s ostium clipping.

  7. Tracheoesophageal fistula in utero: 22 cases

    International Nuclear Information System (INIS)

    A retrospective review of 22 infants born with tracheoesophageal fistula (TEF) detected on in utero US was performed. In addition, ten cases reported in the literature were reviewed. TEF or esophageal atresia should be considered when there is polydramnios and the stomach is not fluid filled; these findings were seen in 32% of the cases. Amniotic fluid flows freely through some TEFs, resulting in a normal amount of amniotic fluid and a fluid-filled stomach (6 of 22 cases), while in other cases the fluid does not traverse the fistula easily and polyhydramnios results. Polyhdramnios was present in 62% of the cases we reviewed and was the most common sonographic finding. The earliest age at which polyhdramnios was diagnosed was 24 weeks. Associated abnormalities are seen in 50%-70% of cases of TEF and are a major contributing factor to morbidity and mortality. Sonography will continue to miss many cases of TEF; however, when TEF is suspected from fetal US (i.e., polyhdramnios and no fluid-filled stomach, or polyhdramnios with no etiology identified), an improved outcome is expected

  8. Congenital esophageal atresia with tracheo-esophageal fistula

    International Nuclear Information System (INIS)

    Three cases of esophageal atresia with tracheo-esophageal fistula. 1). Case 1: A female infant birth Wt. 1.95 kg , Apgar Score 10, Skeletal anomalies, was delivered after a pregnancy compeicated by hydroamnious on Aug. 17, 1970. The family history was not contributory. 2) Case 2: A male infant birth Wt. 2.8 kg , Apgar Score 8, was forcep delivered after a pregnancy on Feb. 8, 1970. This infant is twin. The family history was not contributory. 3) Case 3: A female infant birth Wt. 2.22 kg , Apgar Score 10, was C-section after a pregnancy on May, 16. 1970. The family history was not contributory. All cases: After 24 hours 5% glucose solution was given and immediately vomited and some of it regurgitating through the nose and mouth with associated cyanosis and dyspnea. A catheter was inserted through the nose into the esophagus under diagnosis of the esophageal atresia

    The objectives of this study were to demonstrate that the length of the tracheoesophageal voice prosthesis changes over time and to determine whether the prosthesis length over time increased, decreased, or showed no predictable change in size. A retrospective chart review was performed at a tertiary care referral center. Patients who underwent either primary or secondary tracheoesophageal puncture between January 2006 and August 2014 were evaluated. Patients were excluded if the tracheoesophageal prosthesis size was not consistently recorded or if they required re-puncturing for an extruded prosthesis. Data analyzed included patient demographics and the length of the tracheoesophageal voice prosthesis at each change. A total of 37 patients were identified. The mean age was 64 years. Seventy-six percent were male. 24 % underwent primary tracheoesophageal puncture and 76 % underwent secondary tracheoesophageal puncture. The length of the prosthesis decreased over time (median Kendall correlation coefficient = -0.60; mean = -0.44) and this correlation between length and time was significant (p = 0.00085). Therefore, in conclusion, tracheoesophageal prosthesis length is not constant over time. The tracheoesophageal wall thins, necessitating placement of shorter prostheses over time. Patients with a tracheoesophageal voice prosthesis will require long-term follow-up and repeat sizing of their prosthesis. Successful tracheoesophageal voicing will require periodic reevaluation of these devices, and insurers must, therefore, understand that long-term professional care will be required to manage these patients and their prostheses.

    Full Text Available The incidence of tracheo-esophageal (TO fistula is on the rise, especially after palliative management for esophageal malignancies. We report a case of cancer of esophagus who after chemotherapy and radiotherapy developed TO fistula. Placement of an esophageal stent helped him in taking food orally, but his cough and dyspnoea continued to worsen. Fibreoptic bronchoscopy demonstrated a severely compressed trachea secondary to protrusion of esophageal stent which responded very well to an Ultraflex-covered tracheal stent and the patient achieved relief from cough and dyspnoea.

    Full Text Available Hodgkin lymphoma is a highly curable cancer with modern therapy, with five-year survival rates in excess of 80%. However, the natural history of the untreated disease is largely unknown. We present the case of a patient with Hodgkin lymphoma who went untreated for over 5 years due to patient choice. Eventually, the patient developed hypoxemia, significant weight loss, and a tracheoesophageal fistula. After a placement of a gastrostomy tube and tracheal stent, treatment with standard chemotherapy was initiated. The patient achieved an excellent response, the fistula closed without further intervention, and there is no evidence of relapse six years later. Even in a patient with significant Hodgkin-lymphoma-related sequelae, standard therapy can result in excellent long-term outcomes.

    Full Text Available A common upper airway and digestive tract is a rare congenital anomaly that is usually fatal and its exact incidence is not known. It is a diagnostic challenge as it requires high index of suspicion. It should be considered in a neonate with respiratory distress in a non-vigorous baby requiring endotracheal intubation, which is difficult even in expert hand. We present a newborn with suspected tracheo-esophageal fistula that was diagnosed intraoperatively to have absent upper blind pouch of the esophagus and on autopsy found to have laryngeal atresia with absent vocal cords and a common aerodigestive tract continuing distally with trachea. The neonate was ventilated with endotracheal tube (ETT placement which in retrospect we came to know that it was in the esophagus. The neonate also had associated multiple congenital anomalies of VACTERL association. The importance of teamwork between neonatologist, pediatric surgeon, anesthesiologist, and radiologist is highlighted for diagnosis and management of such rare cases.

    Full Text Available Background: The purpose of this study was to investigate outcomes of surgical repair of esophageal atresia (EA or tracheoesophageal fistula (TEF in newborns, with respect to incidence of death and other complications in early or late operations. Methods: Charts of all 80 infants with EA/TEF, operated in Alzahra hospital (A tertiary hospital of Isfahan University of Medical Sciences from 2002 to 2004 were reviewed. Patients were designed in two groups as, primary and delayed repair groups. Patients demographics, frequency of associated anomalies, and details of management and outcomes were studied. Results: There were 48 male and 32 female patients with a frequency of 28(35% preterm infant and mean birth weight of 2473±595 g. Overall survival rate was 71.2%. Mortality rate in delayed repair group was significantly higher than the other one (22.5% vs. 6.3% but with matching, according to full term/preterm proportion, the significant differences were failed. Female sex and being preterm were the most powerful predictors of death (nearly odds ratio=7 for both. Conclusion: in this study mortality and complications rates are higher in delayed repair than early one, although our data proposed that in absence of sever life threatening anomalies the most important factor for death is gestational age and female sex, and primary repair is opposed to it. Although mortality rate and complications are equal in two strategies, with matching cases for being preterm, but primary repair stays the better choice due to economic considerations.

    Go Miyano

    2015-01-01

    Full Text Available We describe herein a case of unilateral pulmonary agenesis (PA with oesophageal atresia (EA/tracheoesophageal fistula (TEF that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4 th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up.

    Full Text Available Congenital H-type tracheoesophageal fistula (TEF in adults is a rare presentation and can test the diagnostic acumen of a surgeon, endoscopist, and the radiologist. These undetected fistulas may present as chronic lung disease of unknown origin because repeated aspirations can lead to recurrent lung infections and bronchiectasis. Congenital TEFs should be considered in the diagnosis of infants and young adults with recurrent respiratory distress and/or infections. Here, we present the successful management of this rare case in an adult patient.

    Coran, Arnold G

    2013-10-01

    This article presents a 30-year review of 38 recurrent tracheoesophageal fistulas. The initial 26 cases were presented in 2009 at the annual meeting of the British Association of Pediatric Surgeons and the European Association of Pediatric Surgeons Joint Conference and published in the Journal of Pediatric Surgery (Bruchet al. J Pediatr Surg 45:337-340, 2010). In the initial cohort of 26 patients, 18 had a leak after their primary operation and 22 had respiratory symptoms leading to the discovery of the recurrent fistula. The diagnosis was made by a contrast study in 24. The repairs entailed replacing a catheter through the fistula, separating the trachea and esophagus completely using sharp dissection and placing vascularized tissue, either pleura or pericardium between the suture lines. Postoperative complications included seven anastomotic leaks, four strictures and three recurrent fistulas. Long-term follow-up (median of 84 months) showed that 21 took all of their nutrition by mouth, three were tube fed and two required a combination of both. Of the 23 patients with growth chart data, 16 fell into the first quartile of the growth chart, whereas none fell between the 75th and 100th percentile. In conclusion, this initial series of 26 patients along with the updated additional series of 12 patients is the largest series thus far reported in the literature. All 38 patients represent the characteristics of recurrent tracheoesophageal fistulas, including techniques to make the diagnosis and to provide a secure closure of the fistula, and the long-term outcomes of these patients.

    Full Text Available Congenital tracheo-esophageal fistula without esophageal atresia was diagnosed on barium swallow radiography and esophagoscopy findings in an adult patient presenting with difficult in swallowing. The fistulous opening seen on the anterior wall of the esophagus led to the trachea. On bronchoscopy, the tracheal opening was located posteriorly 5 cm below the vocal cords. Successful repair was undertaken via a left cervical approach. The anatomical and developmental basis for the preferred approach is discussed with a brief literature review on the subject.

    Oesophageal atresia (EA) and tracheoesophageal fistula (TEF) is one of the congenital anomaly occurring in the newborns with the incidence of 1 in 2500 births seen worldwide. A retrospective review of newborns admitted to Hospital Sultanah Bahiyah (HSB) from 1st January 2000 to 31st December 2009 was done. The objective was to look at the influence of birth weight, time of surgical intervention, presence of other congenital anomaly and presence of preoperative pneumonia to the immediate outcome (mortality) of the surgery. There were 47 patients with oesophageal atresia, out of which 26 (55%) were males and 21 (45%) females. The distribution of patients by race were 34 Malays (72%), 9 Chinese (19%) and 4 Indians (9%). The birth weight of the babies range from 0.8 kg to 4.0 kg and there was a significant association with the outcome of the surgery (pborn with congenital malformation and there was a significant association with the outcome of the surgery (p<0.05). Based on the chest roentgenogram, 20 (43%) of them had pneumonia with significant association with the outcome (p<0.05). The mortality rate is 23% and the causes of death were pneumonia (36%), renal failure (18%), cardiac malformation (18%) and multiple congenital malformations (28%). The outcome of EA and TEF is determined mainly by birth weight, congenital malformations and presence of preoperative pneumonia in HSB. PMID:23466767

  9. Congenital esophageal stenosis associated with esophageal atresia/tracheoesophageal fistula: clinical and radiologic features

    International Nuclear Information System (INIS)

    Congenital esophageal stenosis (CES) can be associated with esophageal atresia/tracheoesophageal fistula (EA/TEF). Because there are a variety of degrees of obstruction and symptoms of CES, it is frequently difficult to make a pre- and post-operative diagnosis of the distal CES associated with EA/TEF. To evaluate the clinical and radiologic features of congenital esophageal stenosis associated with esophageal atresia/tracheoesophageal fistula. We retrospectively reviewed postoperative esophagograms and medical records of 187 children (107 boys, 80 girls) who had primary repair of EA/TEF from 1992 to 2009 at our institution. We evaluated the incidence of CES, clinical findings, radiologic features and management of CES in these children. CES was diagnosed in 22 of 187 EA/TEF children (12%); one child had double CES lesions, for a total of 23 lesions. Ten of those 22 children (45%) had presented with significant symptoms of esophageal obstruction. The diagnosis of CES was delayed in 10 children (45%) until 1-10 years of age. On esophagogram, CES (n = 23) was located in the distal esophagus (n = 20, 87%) or mid-esophagus (n = 3, 13%). The degree of stenosis was severe (n = 6, 26%), moderate (n = 10, 43%), or mild (n = 7, 30%). Eight children, including two with unsuccessful esophageal balloon dilatation of CES, were treated surgically. Histologic examination revealed tracheobronchial remnant (n = 7) or fibromuscular hyperplasia (n = 1). One child with surgically treated CES developed achalasia at the age of 3 years 9 months. Esophagography after EA/TEF repair should be performed with a high index of suspicion for the presence of distal CES, because the diagnosis and adequate management of CES can often be delayed.

On esophagogram, CES (n = 23) was located in the distal esophagus (n = 20, 87%) or mid-esophagus (n = 3, 13%). The degree of stenosis was severe (n = 6, 26%), moderate (n = 10, 43%), or mild (n = 7, 30%). Eight children, including two with unsuccessful esophageal balloon dilatation of CES, were treated surgically. Histologic examination revealed tracheobronchial remnant (n = 7) or fibromuscular hyperplasia (n = 1). One child with surgically treated CES developed achalasia at the age of 3 years 9 months. Esophagography after EA/TEF repair should be performed with a high index of suspicion for the presence of distal CES, because the diagnosis and adequate management of CES can often be delayed.

    Full Text Available The proximal q arm of chromosome 15 contains breakpoint regions BP1–BP5 with the classic deletion of BP1–BP3 best known to be associated with Prader-Willi and Angelman syndromes. The region is approximately 500 kb and microdeletions within the BP1-BP2 region have been reported in patients with developmental delay, behavioral abnormalities, and motor apraxia as well as dysmorphic features including hypertelorism, cleft or narrow palate, ear abnormalities, and recurrent upper airway infections. We report two patients with unique, never-before-reported 15q11.2 BP1-2 microdeletion syndrome findings, one with proximal esophageal atresia and distal tracheoesophageal fistula (type C and one with congenital cataracts. Cataracts have been described in Prader-Willi syndrome but we could not find any description of cataracts in Angelman syndrome. Esophageal atresia and tracheoesophageal fistula have not been reported to our knowledge in either syndrome. A chance exists that both cases are sporadic birth defects; however, the findings of the concomitant microdeletion cannot be overlooked as a possible cause. Based on our review of the literature and the presentation of our patients, we recommend that esophageal atresia and distal tracheoesophageal fistula as well as congenital cataracts be included in the phenotypic spectrum of 15q11.2 BP1-2 microdeletion syndrome.

    2011-01-01

    Full Text Available Background: A significant number of esophageal atresia and tracheoesophageal fistula patients have long gaps and a high propensity to leak. Anastomotic leak in esophageal atresia is associated with a significant morbidity and mortality. Aim : In a prospective randomized trial, we analyzed the risk factors leading to anastomotic dehiscence and studied the effect of pleural wrap as an additional vascular cover around the esophageal anastomosis. Materials and Methods: Forty patients were divided into two groups A and B randomly. In 20 patients of group A, pleural wrap was utilized for covering the anastomosis and in 20 patients of group B, no such wrap was utilized. Results: Both the groups were comparable regarding age, sex, weight, gap length, tension at anastomosis and the hospital stay. The overall leak rate was 25% (10/40 in both the groups. The leak rate was not significantly different in two groups whenever a gap length was less than 2 cm or more than 3 cm. However, for a gap length of 2-3 cm, the leak rate in group A was 18% (2/11 and in group B was 50% (4/8 (P = 0.05. Thirty percent (3/10 of patients, whose anastomosis was under tension, leaked in group A as compared to 75% (6/8 in group B patients (P = 0.001. Conclusions: Use of pleural wrap was associated with less anastomotic dehiscence in patients with moderate gap esophageal atresia (2-3 cm especially when the anastomosis was under tension.

  15. Endoscopic Stenting and Clipping for Anastomotic Stricture and Persistent Tracheoesophageal Fistula after Surgical Repair of Esophageal Atresia in an Infant

    Full Text Available Anastomotic stricture (AS and recurrent tracheoesophageal fistula (TEF are two complications of surgical repair of esophageal atresia (EA. Therapeutic endoscopic modalities include stenting, tissue glue, and clipping for TEF and endoscopic balloon dilation bougienage and stenting for esophageal strictures. We report herein a two-month infant with both EA and TEF who benefited from a surgical repair for EA, at the third day of life. Two months later he experienced deglutition disorders and recurrent chest infections. The esophagogram showed an AS and a TEF confirmed with blue methylene test at bronchoscopy. A partially covered self-expanding metal type biliary was endoscopically placed. Ten weeks later the stent was removed. This allows for easy passage of the endoscope in the gastric cavity but a persistent recurrent fistula was noted. Instillation of contrast demonstrated a fully dilated stricture but with a persistent TEF. Then we proceeded to placement of several endoclips at the fistula site. The esophagogram confirmed the TEF was obliterated. At 12 months of follow-up, he was asymptomatic. Stenting was effective to alleviate the stricture but failed to treat the TEF. At our knowledge this is the second case of successful use of endoclips placement to obliterate recurrent TEF after surgical repair of EA in children.

    Full Text Available Aim: This study was aimed at identifying factors which may affect the gap length in cases of esophageal atresia with tracheoesophageal fistula (EA-TEF and whether gap length plays any role in determining the outcome. Materials and Methods: All consecutive cases of EA-TEF were included and different patient parameters were recorded. Plain radiographs with a nasogastric tube in the upper esophagus were taken. Patients were grouped into T1-T2; T2-T3; T3-T4; and T4 depending on the thoracic vertebral level of the arrest of the tube. During surgery, the gap length between the pouches was measured using a Vernier caliper and the patients were grouped into A, B, and C (gap length >2.1 cm; >1-≤2 cm and ≤1 cm. The operative gap groups were compared with the radiography groups and the other recorded parameters. Results: Total numbers of cases were 69. Birth weight was found to be significantly lower in Group A (mean = 2.14 kg as compared to Group B (mean = 2.38 kg and Group C patients (mean = 2.49 kg (P = 0.016. The radiographic groups compared favorably with the intraoperative gap length groups (P < 0.001. The need for postoperative ventilation (70.83% in Group A vs. 36.84% in Group C, P = 0.032 and mortality (62.5%, 26.9% and 15.8% in Group A, B, and C, respectively, P = 0.003 co-related significantly with the gap length. Conclusion: Birth weight had a direct reciprocal relationship with the gap length. Radiographic assessment correlated with intraoperative gap length. Higher gap length was associated with increased need for postoperative ventilation and poor outcome.

    Recurrent tracheoesophageal fistula (TEF) is still difficult to diagnose and repair. In almost all cases, recurrence appears relatively soon after the primary surgery. We herein describe a case of recurrent TEF that appeared 10 years after the primary repair. At 2 years of age, the patient suffered from mental retardation due to encephalitis and developed a hiatus hernia with gastro-esophageal reflux. He underwent the repair of a hiatus hernia and fundoplication at 3 years of age. However, the hiatus hernia recurred 6 months after the operation. The patient suffered from recurrent pneumonia for 6 years after the appearance of the recurrent hiatus hernia. At 9 years of age, he was hospitalized frequently due to recurrent severe pneumonia. After admission at 9 years of age, an endoscopic study under general anesthesia was performed and revealed subglottic stenosis and a dilated esophagus with a recurrent hiatus hernia. Tracheotomy or laryngotracheal separation was first planned in order to improve his upper airway and facilitate the safer repair of the recurrent hiatus hernia. After laryngotracheal separation, the patient still suffered from severe pneumonia. In addition, a small volume of nutritional supplement was aspirated from the tracheostomy. Thus, recurrent TEF was suspected. Tests using dye under both esophagoscopy and bronchoscopy confirmed recurrent TEF. The fistula recurred in the cervical area because of the elevation of the esophagus due to the recurrent hiatus hernia. The fistula was surgically closed, with a sternothyroid muscle flap to prevent re-recurrence. At 4 months after this operation, the recurrent hiatus hernia was repaired. Thereafter, the patient's respiratory symptoms showed a dramatic improvement. The patient is now doing well and free from further recurrences of TEF and hiatus hernia at 2 years after the final operation. PMID:27589983

    Full Text Available The tracheo-esophageal fistula without esophageal atresia is a rare type esophageal malformation. It has a multifactorial etiology including environmental and genetic factors. Common clinical manifestations are coughing and choking after meals, cyanosis and/or recurrent pneumonia. Diagnosis requires a high clinical suspicion index. Fistula confirmation is done with imaging studies including upper digestive series, video-fluoroscopy or with the use of bronchoscopy wich allows direct visualization of the fistula or methylene blue passage through the abnormal communication. Fistula closure can be done endoscopically or surgically, in both cases with good results.

    2015-01-01

    Full Text Available Introduction: Tracheoesophageal voice prosthesis is highly effective in providing speech after total laryngectomy. Although it is a safe method, in certain cases dilatation or leakage occurs around the prosthesis that needs closure of tracheoesophageal fistula. Both non-surgical and surgical methods for closure have been described. Surgical methods are used when non-surgical methods fail. We present the use of the sternocleidomastoid musculocutaneous (SCMMC transposition flap for the closure of tracheoesophageal fistula. Materials and Methods: An incision is made at the mucocutaneous junction circumferentially around the tracheostoma. Tracheoesophageal space is dissected down to and beyond the fistula. The tracheoesophageal tract is divided. The oesophageal mucosa is closed with simple sutures. Then SCMMC transposition flap is raised and transposed to cover sutured oesophagus and the defect between the oesophagus and the trachea. Results: This study was done prospectively over a period of 1 year from June 2012 to May 2013. This technique was used in patients with pliable neck skin. In nine patients, this procedure was done (inferior based flap in nine cases and it was successful in eight patients. In one case, there was dehiscence at the leading edge of flap with oesophageal dehiscence, which required a second procedure. In two cases, there was marginal necrosis of flap, which healed without any intervention. Nine patients in this series were post-radiation. Conclusion: This method of closure is simple and effective for patients with pliable neck skin, who require permanent closure of the tracheoesophageal fistula.

    VACTERL (vertebral anomalies, anal atresia, cardiac defect, tracheoesophageal fistula, renal anomaly, limb anomalies) is an association of anomalies with a wide spectrum of phenotypic expression. While the majority of cases are sporadic, there is evidence of an inherited component in a small number of patients as well as the potential influence of nongenetic risk factors (maternal diabetes mellitus). Presence of hydrocephalus has been reported in VACTERL patients (VACTERL-H) in the past, with some displaying branchial arch anomalies. We report the unique case of an infant of diabetic mother with VACTERL association and a branchial arch anomaly-in the absence of hydrocephalus. PMID:26929876

    Although appendiceal anatomical anomalies are very rare, understanding of the anatomical details of these anomalies is important for surgery. In this case report, we present images from multi-detector row computed tomography (MDCT) and histological findings of a rare anatomical appendiceal anomaly originating from the cecum and opening into the terminal ileum like a bridge. These anatomical details were clearly depicted on MDCT with multi-planar reconstruction. MDCT demonstrated a communication between the appendix and terminal ileum. Histological analysis revealed that a normal mucosal layer was maintained from the appendix to the connected ileum, without any evidence of inflammatory or neoplastic changes, and only thickening of the muscular layer of the appendix was identified. Based on these histological findings, the appendix was considered to represent an anatomical anomaly rather than secondary fistula caused by inflammation or neoplasm, which has not yet been reported.

  10. Imaging of a coronary vessel anomaly with aneurysm and arteriovenous fistula by means of MR bolustracking technique

    International Nuclear Information System (INIS)

    Coronary arteriovenous fistulas are very rare findings and predominantly drain into the right atrium or the right ventricle. Echocardiography and X-ray coronary angiography are established methods in the detection of these anomalies. It is reported on a patient, in whom an anomaly with dilatation of the circumflex coronary artery, aneurysma and drainage over an arteriovenous fistula in the right ventricle was observed. By means of magnetic resonance tomography with bolustracking technique the vessel course and the dynamics of perfusion are noninvasively shown beside the imaging using TSE-sequence. The method of multiple injections of 2 ml Gd-DTPA makes the bolustracking technique to an ideal tool for the determination of the individual vessel course, the haemodynamics and draining direction of a coronary anomaly with fistula.

    Full Text Available Congenital gastrointestinal anomalies include spectrum of malformations, simple ones as well as complex, which are associated with anomalies of other organs and systems of organs. Most infants (50-60% with imperforate anus also have genitourinary, cardiovascular, gastrointestinal and vertebral anomalies. This case report is of a female newborn with prenatally diagnosed duodenal atresia and right hydronephrosis. Clinical investigation revealed an imperforate anus with vestibular fistula. A plain abdominal x-ray showed a "double-bubble” sign, characteristic for duodenal atresia. Intraluminal membrane was excised and sigmoid colostomy was performed in general anesthesia on the first day of life. Ultrasound and intravenous pyelography confirmed a hydronephrotic right kidney and obstructive megaureter after Pena. In the fifth month of life, the ureter was tapered and reimplanted. Six months later, posterior sagittal anorectoplasty was performed. In the sewentheenth month of life the colostomy was closed. This child attained normal growth and development, normal bowel control, fecal continence without soiling, obstipation and urinary infections.

    Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, otitis media, and sinusitis. Lacrimal duct obstruction and fistula were managed successfully with endoscopic dacryocystorhinostomy (DCR) which is a good alternative to lacrimal probing or open DCR in such a case. PMID:26655010

    2013-12-01

    Full Text Available Introduction. Esophageal atresia encompasses a group of congenital anomalies comprising of an interruption of the esophageal continuity with or without a persistent communication with the trachea. Esophageal atresia with tracheoesophageal fistula (type C accounts for 85% of all esophageal atresia. Minimally invasive approach to correct esophageal atresia with distal fistula is becoming more generally accepted. The outcome of these technique are critically analyzed and compared with results from open repair. We present one case of type IIIB esophageal atresia treated by a thoracoscopic approach. Case Report. The patient was a 2-days-old infant male, weight 3 kg with esophageal atresia and distal tracheoesophageal fistula without other associated disease. A polidramanios was detected in prenatal age by a prenatal ultrasound evaluation. He underwent to a thoracoscopic repair of the defect. The operation was approached through the right chest using a three-trocar technique (three 5-mm with the patient placed in a three-quarter prone position. The azygos vein was ligated by Ligature device. The fistula was ligated by two resorbable stiches suture and dissected, the proximal esophagus was opened and an anastomosis was made over a 6 Ch nasogastric tube with interrupted and resorbable stiches suture. On the postoperative day 7, gastrografin swallow was performed and oral feeding was started. The patient’s six month upper Gastrointestinal barium studies was normal. Discussion and conclusion. Thoracoscopic repair of esophageal atresia is considered to be one of the more advanced and most difficult pediatric surgical procedures and it undoubtely has necessary an elevated learning curve. The minimally invasive approach was larged accepted in the last ten years also for the well documented sequelae of traditional open repair of esophageal atresia. More experience is needed to determine the exact place of this approach.

    Leakage around the prosthesis is one of the worst problems afflicting patients fitted with tracheoesophageal (TE) voice prosthesis. Removing the prosthesis for a few days can reduce the size of the fistula, or the leakage may be eliminated simply by replacing the prosthesis. In cases that are refractory to such treatment, the perifistular injection of different types of autologous, heterologous or alloplastic substances has been proposed. A new kind of silicone, previously available abroad, has recently appeared on the Italian market as well; constituted by polydimethylsiloxane textured elastomers (Bioplastique) for soft tissue implants, it appears to guarantee excellent standards of long-term safety and stability. Three patients fitted with Provox2 tracheoesophageal voice protheses who had been experiencing leakage for about 4 months underwent Bioplastique implant procedures. The correction of the fistula size was easy to accomplish and well tolerated by the patients. There was no sign of inflammation, formation of granulomas or other pathological modifications, and the size of the fistula, together with its fluid-tightness, remained stable in time. From our point of view, the Bioplastique implant appears to provide valid and effective treatment of gaping TE fistulas. PMID:12510340

    Surgical glues have been used in pediatric surgery because of the fragility of tissue, and to prevent major surgeries. The present report describes our experience with using a new cyanoacrylate Glubran 2 (Viareggio, Italy) in the treatment of five cases of tracheoesophageal atresia with fistula (one fistula protection, three recurrent fistula, and one unstable patients), two cases of hypospadias, one case of vesicutanouse fistula after bladder extrophy, and one case of cloacal extrophy from January-December 2008. Three cases of recurrent tracheoesophageal atresia with fistula were treated by bronchoscpic glue injection. The other two cases benefited from glue through its ability to plug the fistula and to act as a protecting layer on anastomosis. In two cases with hypospadias excessive use of the glue caused skin necrosis, which was repaired. The wounds of cloacal extrophy were protected from nearby colostomy contamination and infection, and the vesicocutanouse fistula was closed by deepithelialization and sealing with glue. Based on the outcomes of the cases, it may be possible to suggest that Glubran 2 may be used safely in Pediatric Surgery as a sealant for the prevention and treatment of fistulas. PMID:23365480

    This study investigated whether trachea pressures during brass instrument play of laryngectomised patients are within the range of those measured during tracheoesophageal voicing, and whether application of an automatic speaking valve can 'free' both hands to play a brass instrument. Objective assessment of voicing and music playing parameters was carried out in 2 laryngectomised patients with a low-pressure indwelling voice-prosthesis able to play brass instruments (tenor horn and slide trombone): sound pressure levels in dB, maximum phonation time in seconds and trachea pressures in mmHg; videofluoroscopy, stroboscopy and digital high speed endoscopy to assess neoglottis vibration and opening. The dynamic range of the voice in the patients was 29 and 20 dB, and maximum phonation time was 22 and 19 sec, respectively; intratracheal pressures during voicing varied from 7 mmHg for the softest /a/ to 49 mmHg for the loudest /a/. For brass instrument play, the intratracheal pressures varied from 14 mmHg for the softest tone to 48 mmHg for the loudest tone. Imaging confirmed earlier findings that the neoglottis is closing and vibrating during voicing and remains 'open' without vibrations during music play, indicating good neoglottis control and innervation. From these objective measurements, we can conclude that trachea pressures during brass instrument play are within physiological ranges for tracheoesophageal voicing with a low-pressure indwelling voice-prosthesis. Furthermore, it was shown that application of a stable baseplate for retaining an automatic speaking valve and an additional customisable 'neck brace' makes bimanual play possible again.

  20. The impact of postoperative supraclavicular radiotherapy on tracheoesophageal groove lymph node metastasis in esophageal carcinoma

    International Nuclear Information System (INIS)

    Objective: To evaluate the prognostic factors of tracheoesophageal groove lymph node (TEGLN) metastasis in postoperative esophageal carcinoma. Methods: From January 1996 to December 1997, 101 postoperative cervical and thoracic esophageal carcinoma patients proved absence from tracheoesophageal groove lymph node (TEGIAN) metastasis before and after operation by physical examination and computer tomography examination were entered into this study. The patients were divided into three groups according to the treatment of supraclavicular region: no prophylactic radiotherapy (group A-, 30 patients); prophylactic radiotherapy with local dose < 45 Gy (Group B-, 71 patients); and prophylactic radiotherapy with local dose ≥45 Gy (Group C-, 19 patients). Radiotherapy was delivered by cobalt- 60 or 6 MV X-ray with the prescribed dose normalized to the point of tracheoesophageal groove, i. e, 5 cm in depth. The tracheoesophageal groove lymph node metastasis after treatment was observed. Results: The incidence of tracheoesophageal groove lymph node metastasis was 20% (6/30), 9.6% (5/71) and 0% (0/19) in groups A, B and C. Univariate analysis showed that there was significant difference of TEGLN metastasis between groups A and C only (P=0.039), but higher dose to supraclavicular region tended to lower the incidence of TEGLN metastasis. Multivariate analysis showed that only prophylactic radiotherapy to the supraclavicular region was independent prognostic factor for TEGLN metastasis (P=0.037). Gender, primary tumor site and pathological stage had no significant impact on TEGLN metastasis. Conclusions: Postoperative prophylactic supraclavicular region irradiation can lower the incidence of tracheoesophageal groove lymph node metastasis in esophageal carcinoma. Radiotherapy dose should not be less than 45 Gy and should be routinely normalized to a point 5 cm deep in the tracheoesophageal groove. (authors)

    Full Text Available Introduction: Aphallia is a very rare urogenital anomaly with incidence rate of 1 in 30,000,000. It usually coexists with other anomalies such as cardiovascular anomalies which are incompatible with normal life, and therefore infants are delivered stillbirth or live for a very short period of time. Methods: We present an 18 months old boy with aphallia associated with congenital urethrorectal fistula, bladder and urethral stones. All stones were removed endourologically, recto-urethral fistula was repaired and perincal urethrostomy was performed. Results: The stones were composed of calcium phosphate colonized by klebiella pneumonia and proteus mirabilis. Urethrorectal fistula repairment was confirmed by cystography. Patient was discharged without a urinary catheter. Conclusion: In developed countries, management of such patients is to raise them as females. However, we must consider socio-cultural conditions, parents preference and patients tendency in management of aphallia.

    The present study investigated the aerodynamic differences between standard oesophageal (SE) and tracheoesophageal (TE) speech. Airflow and air pressure values below the pharyngoesophageal segment were obtained from 10 SE and 12 TE superior speakers of Cantonese. Airflow data were directly measured from sustained vowels, and sub-pharyngoesophageal segment pressure was estimated from /ip(h)ip(h)i/ syllables produced by the alaryngeal speakers. Results indicated that SE speech was associated with a lower rate of airflow and a higher pressure below the pharyngoesophageal segment than TE speech. SE and TE speakers exhibited an average airflow and sub-pharyngoesophageal segment pressure values of 70.50 mL/s and 134.15 mL/s, and 25.13 cm H(2)O and 22.61 cm H(2)O, respectively. Using the airflow and sub-pharyngoesophageal segment pressure, neoglottal resistance values were derived. The estimated neoglottal resistance was greater in SE speakers than in TE speakers. It is speculated that such difference in neoglottal resistance may be related to the use of different air reservoir mechanisms between SE and TE speakers. Such information will help speech-language pathologists design better speech therapy regimes for SE and TE speakers by understanding more about the difference between SE and TE phonation.

    The congenital H-type fistula between the anorectum and genital tract besides a normal anus is a rare entity in the spectrum of anorectal anomalies. We described a girl with an anovestibuler H-type fistula and left vulvar abscess. A 40-day-old girl presented symptoms after her parents noted the presence of stool at the vestibulum. On the physical examination, anus was in normal location and size, and had normal sphincter tone. A vestibuler opening was seen in the midline just below of the hymen. A fistulous communication was found between the vestibuler opening and the anus, just above the dentate line. There was a vulvar abscess which had a left lateral vulvar drainage opening 15 mm left lateral to the perineum. After the management of local inflammation and abscess, the patient was operated for primary repair of the fistula. A protective colostomy wasn′t performed prior the operation. A profuse diarrhea started after 5 hours of postoperation. After the diarrhea, a recurrent fistula was occurred on the second postoperative day. A divided sigmoid colostomy was performed. 2 months later, and anterior sagital anorectoplasty was reconstructed and colostomy was closed 1 month later. Various surgical techniques with or without protective colostomy have been described for double termination repair. But there is no consensus regarding surgical management of double termination.

    Objective To investigate the treatment of rectourethral fistula. Methods Eleven cases of male patients with rectourethral fistula were treated in our department from 2011 to 2015. Age 16–66 years old. Causes: three cases of patients with congenital closed anus, four cases of traumatic pelvic fracture with urethral distraction and rectum injury, four cases after radical prostatectomy. The size of the fistula was 0.5–1.5 cm. In addition to the leakage of urine in the large fistula, urine mixed with stool samples. Three patients with congenital closed anal postoperative patients with posterior or anterior median sagittal approach for resection of the fistula, hierarchical closed urethral and rectal wall defect, at least three layer (between the urethral and rectal suture layer), indwelling catheter for 3–4 weeks, no cystostomy. Sigmoid colostomy underwent prior to the surgery. Of which six cases were repaired by perineal approach, one case by abdominal perineal approach, one case by abdominal repair. According to size of fistula and the surrounding scar decide whether or not to adopt tissue interposition, this group of five cases with gracilis muscle flap, one case with bulbocavernosus muscle flap interposed between the rectum and urethra; one case repaired by sigmoid colon pull-through procedure. Post-operation indwelling catheterization for 3–4 weeks with cystostomy. Results A total of 10 patients were successful, and no leakage of urine was found after removal of the catheter. One patient improved, occasionally a small amount of drops of urine voiding from anus. Reoperation was successful after 6 months. Recovered enteric continuity 3–6 months post-operation. Conclusions The median sagittal approach provide good exposure for the repair of congenital rectourethral fistula; perineal approach is a good choice for patients caused by trauma or surgery; complete resection of scar around the fistula, tension-free anastomosis, tissue interposition and sigmoid

    Full Text Available Abstract A coronary arterial fistula is a connection between one or more of the coronary arteries and a cardiac chamber or great vessel. This is a rare defect and usually occurs in isolation. Its exact incidence is unknown. The majority of these fistulas are congenital in origin although they may occasionally be detected after cardiac surgery. They do not usually cause symptoms or complications in the first two decades, especially when small. After this age, the frequency of both symptoms and complications increases. Complications include 'steal' from the adjacent myocardium, thrombosis and embolism, cardiac failure, atrial fibrillation, rupture, endocarditis/endarteritis and arrhythmias. Thrombosis within the fistula is rare but may cause acute myocardial infarction, paroxysmal atrial fibrillation and ventricular arrhythmias. Spontaneous rupture of the aneurysmal fistula causing haemopericardium has also been reported. The main differential diagnosis is patent arterial duct, although other congenital arteriovenous shunts need to be excluded. Whilst two-dimensional echocardiography helps to differentiate between the different shunts, coronary angiography is the main diagnostic tool for the delineation of the anatomy. Surgery was the traditional method of treatment but nowadays catheter closure is recommended using a variety of closure devices, such as coils, or other devices. With the catheter technique, the results are excellent with infrequent complications. Disease name and synonyms Coronary arterial fistulas Coronary arterial fistulas or malformations

    Full Text Available Parotid fistula is a cause of great distress and embarrassment to the patient. Parotid fistula is most commonly a post-traumatic situation. Congenital parotid salivary fistulas are unusual entities that can arise from accessory parotid glands or even more infrequently, from normal parotid glands through an aberrant Stensen′s duct. The treatment of fistulous tract is usually surgical and can be successfully excised after making a skin incision along the skin tension line around the fistula opening. This report describes a case of right accessory parotid gland fistula of a 4-year-old boy with discharge of pus from right cheek. Computed tomography (CT fistulography and CT sialography demonstrated fistulous tract arising from accessory parotid gland. Both CT fistulography and CT sialography are very helpful in the diagnosis and surgical planning. In this case, superficial parotidectomy is the treatment of choice. A detailed history, clinical and functional examination, proper salivary gland investigations facilitates in correct diagnosis followed by immediate surgical intervention helps us to restore physical, psychological health of the child patient.

    Down syndrome (DS) is the most common congenital anomaly widely studied for at least 150 years. However, the type and the frequency of congenital anomalies associated with DS are still controversial. Despite prenatal diagnosis and elective termination of pregnancy for fetal anomalies, in Europe, from 2008 to 2012 the live birth prevalence of DS per 10,000 was 10. 2. The objectives of this study were to examine the major congenital anomalies occurring in infants and fetuses with Down syndrome. The material for this study came from 402,532 consecutive pregnancies of known outcome registered by our registry of congenital anomalies between 1979 and 2008. Four hundred sixty seven (64%) out of the 728 cases with DS registered had at least one major associated congenital anomaly. The most common associated anomalies were cardiac anomalies, 323 cases (44%), followed by digestive system anomalies, 42 cases (6%), musculoskeletal system anomalies, 35 cases (5%), urinary system anomalies, 28 cases (4%), respiratory system anomalies, 13 cases (2%), and other system anomalies, 26 cases (3.6%). Among the cases with DS with congenital heart defects, the most common cardiac anomaly was atrioventricular septal defect (30%) followed by atrial septum defect (25%), ventricular septal defect (22%), patent ductus arteriosus (5%), coarctation of aorta (5%), and tetralogy of Fallot (3%). Among the cases with DS with a digestive system anomaly recorded, duodenal atresia (67%), Hirschsprung disease (14%), and tracheo-esophageal atresia (10%) were the most common. Fourteen (2%) of the cases with DS had an obstructive anomaly of the renal pelvis, including hydronephrosis. The other most common anomalies associated with cases with DS were syndactyly, club foot, polydactyly, limb reduction, cataract, hydrocephaly, cleft palate, hypospadias and diaphragmatic hernia. Many studies to assess the anomalies associated with DS have reported various results. There is no agreement in the literature as to

  18. Cholecystocolic fistula: A diagnostic enigma

    International Nuclear Information System (INIS)

    Cholecystocolic fistula is a rare biliary-enteric fistula with a variable clinical presentation. Despite modern diagnostic tools, a high degree of suspicion is required to diagnose it preoperatively. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is a cholecystoduodenal (70%), followed by cholecystocolic (10-20%), and the least common is the cholecystogastric fistula accounting for the remainder of cases. These fistulae are treated by open as well as laparoscopic surgery, with no difference in intraoperative and postoperative complications. We report here a case of obstructive jaundice, which was investigated with a plain film of the abdomen, abdominal ultrasonography, and endoscopic retrograde cholangiopancreatography, but none of these gave us any clue to the presence of the fistula was discovered incidentally during an open surgery and was appropriately treated.

  3. Surgical Management of Enterocutaneous Fistula

    International Nuclear Information System (INIS)

    Enterocutaneous (EC) fistula is an abnormal connection between the gastrointestinal (GI) tract and skin. The majority of EC fistulas result from surgery. About one third of fistulas close spontaneously with medical treatment and radiologic interventions. Surgical treatment should be reserved for use after sufficient time has passed from the previous laparotomy to allow lysis of the fibrous adhesion using full nutritional and medical treatment and until a complete understanding of the anatomy of the fistula has been achieved. The successful management of GI fistula requires a multi-disciplinary team approach including a gastroenterologist, interventional radiologist, enterostomal therapist, dietician, social worker and surgeons. With this coordinated approach, EC fistula can be controlled with acceptable morbidity and mortality.

  4. Arteriovenous fistula following lumbar laminectomy

    International Nuclear Information System (INIS)

    A case of iatrogenic aortocaval fistula is presented. The fistula arose from lumbar disc surgery. Its presence was immediately suspected on ultrasound and computed tomogram, and was promptly confirmed by angiography. Ultrasound and computed tomogram also precisely define the anatomy between the aorta or its branches and the IVC or its tributaries. Sudden deterioration of the patient's condition necessitated surgical correction of the fistula before the elected date. The successful corrective operation is described

  5. Tubercular fistula-in-ano

    International Nuclear Information System (INIS)

    To determine the frequency of tuberculosis in recurrent fistula-in-ano. The study included 100 cases of recurrent fistula-in-ano not responding to conventional surgery. Patients with other co-morbidities such as diabetes mellitus, bleeding disorders or with the evidence of pulmonary, abdominal or intestinal tuberculosis were excluded from this study. Fistulogram was performed in all patients. All the patients were subjected to fistulectomy followed by histopathology of the resected specimen. Thereafter, confirmation of the disease, anti-tuberculous treatment was immediately started and response to treatment was observed after 6 months. Out of the 100 studied patients, 11 cases had biopsy proven tuberculosis in the fistula. All the patients were male. The fistulae were low type, single and usually located posteriorly (n=9) with everted margins. Ten were located within 3 cm of anus. Fistulogram revealed single internal opening. Comparative statistics of tuberculous fistula-in-ano with fistulas due to specific inflammation revealed no major differences. The diagnosed patients of tubercular fistulae-in-ano were observed for at least 6 months after starting anti-tuberculous treatment. They all responded well to anti-tubercular treatment and the fistulae healed without any complication such as recurrence or anal stenosis within 6 months. Tuberculosis should be suspected in case of recurrent fistulae-in-ano, so as to avoid unusual delay in the treatment and miseries to the patient. Appropriate anti-tuberculous therapy leads to healing within 6 months. (author)

    Aorto-duodenal fistulae (ADF) are the most frequent aorto-enteric fistulae (80%), presenting with upper gastrointestinal bleeding. We report the first case of a man with a secondary aorto-duodenal fistula presenting with a history of persistent occlusive syndrome. A 59-year old man who underwent an aortic-bi-femoral bypass 5 years ago, presented with dyspepsia and biliary vomiting. Computed tomography scan showed in the third duodenal segment the presence of inflammatory tissue with air bubbles between the duodenum and prosthesis, adherent to the duodenum. The patient was submitted to surgery, during which the prosthesis was detached from the duodenum, the intestine failed to close and a gastro-jejunal anastomosis was performed. The post-operative course was simple, secondary ADF was a complication (0.3%-2%) of aortic surgery. Mechanical erosion of the prosthetic material into the bowel was due to the lack of interposed retroperitoneal tissue or the excessive pulsation of redundantly placed grafts or septic procedures. The third or fourth duodenal segment was most frequently involved. Diagnosis of ADF was difficult. Surgical treatment is always recommended by explorative laparotomy. ADF must be suspected whenever a patient with aortic prosthesis has digestive bleeding or unexplained obstructive syndrome. Rarely the clinical picture of ADF is subtle presenting as an obstructive syndrome and in these cases the principal goal is to effectively relieve the mechanical bowel obstruction.

  7. Modern management of anal fistula.

    2015-01-01

    Ideal surgical treatment for anal fistula should aim to eradicate sepsis and promote healing of the tract, whilst preserving the sphincters and the mechanism of continence. For the simple and most distal fistulae, conventional surgical options such as laying open of the fistula tract seem to be relatively safe and therefore, well accepted in clinical practise. However, for the more complex fistulae where a significant proportion of the anal sphincter is involved, great concern remains about damaging the sphincter and subsequent poor functional outcome, which is quite inevitable following conventional surgical treatment. For this reason, over the last two decades, many sphincter-preserving procedures for the treatment of anal fistula have been introduced with the common goal of minimising the injury to the anal sphincters and preserving optimal function. Among them, the ligation of intersphincteric fistula tract procedure appears to be safe and effective and may be routinely considered for complex anal fistula. Another technique, the anal fistula plug, derived from porcine small intestinal submucosa, is safe but modestly effective in long-term follow-up, with success rates varying from 24%-88%. The failure rate may be due to its extrusion from the fistula tract. To obviate that, a new designed plug (GORE BioA®) was introduced, but long term data regarding its efficacy are scant. Fibrin glue showed poor and variable healing rate (14%-74%). FiLaC and video-assisted anal fistula treatment procedures, respectively using laser and electrode energy, are expensive and yet to be thoroughly assessed in clinical practise. Recently, a therapy using autologous adipose-derived stem cells has been described. Their properties of regenerating tissues and suppressing inflammatory response must be better investigated on anal fistulae, and studies remain in progress. The aim of this present article is to review the pertinent literature, describing the advantages and limitations of

    2011-01-01

    AIM: To study the clinical characteristics, diagnosis and surgical treatment of congenital bronchoesophageal fistulae in adults. METHODS: Eleven adult cases of congenital bronchoesophageal fistula diagnosed and treated in our hospital between May 1990 and August 2010 were reviewed. Its clinical presentations, diagnostic methods, anatomic type, treatment, and follow-up were recorded. RESULTS: Of the chief clinical presentations, nonspecific cough and sputum were found in 10 (90.9%), recurrent bouts of cough after drinking liquid food in 6 (54.6%), hemoptysis in 6 (54.6%), low fever in 4 (36.4%), and chest pain in 3 (27.3%) of the 11 cases, respectively. The duration of symptoms before diagnosis ranged 5-36.5 years. The diagnosis of congenital bronchoesophageal fistulae was established in 9 patients by barium esophagography, in 1 patient by esophagoscopy and in 1 patient by bronchoscopy, respectively. The congenital bronchoesophageal fistulae communicated with a segmental bronchus, a main bronchus, and an intermediate bronchus in 8, 2 and 1 patients, respectively. The treatment of congenital bronchoesophageal fistulae involved excision of the fistula in 10 patients or division and suturing in 1 patient. The associated lung lesion was removed in all patients. No long-term sequelae were found during the postoperative follow-up except in 1 patient with bronchial fistula who accepted reoperation before recovery. CONCLUSION: Congenital bronchoesophageal fistula is rare in adults. Its most useful diagnostic method is esophagography. It must be treated surgically as soon as the diagnosis is established.

  10. Fistula gastrocólica Gastrocolic fistula

    Alexandre Cruz Henriques

    1999-08-01

    Full Text Available A case of gastrocolic fistula(GCF in a patient with duodenal stenosis who had previously undergone gastroenteric anastomosis is reported. The patient went through hemigastrectomy, partial colectomy and segmental enterectomy with bloc resection. Reconstruction was carried out through Billroth II gastrojejunostomy, jejunojejunostomy and end-to-end anastomosis of the colon. The patient had good post-operative evolution and was discharged from hospital seven days after surgery. GCF should be suspected in patients presenting weight loss, diarrhea and fecal vomiting, mainly with history of peptic ulcer surgery, gastric or colonic malignancy and use of steroidal and nonsteroidal antiinflamatory drugs. Barium enema is the choice test for diagnosis, however, the benign or malignant nature of the lesion should always be evaluated through high digestive endoscopy. Clinical treatment with oral H2-antagonists and discontinuing ulcerogenic medications might be indicated in some cases; surgical treatment is indicated in cases of malignant disease and might be indicated in cases of peptic disease as it treats GCF and also the baseline disease. Some advise upwards colostomy at first. The most used technique is bloc resection, including the fistulous tract, hemigastrectomy and partial colectomy. Gastrectomy, fistulous tract excision and colon suturing may be performed in some cases. The mortality rate is related to metabolic disorders and the recurrence with the use of antiinflammatory drugs.

  11. Experimental model of arteriovenous fistula in pigs

    International Nuclear Information System (INIS)

    To establish an experimental model of arteriovenous fistula in pigs. Ten fistulas were created in eight pigs, and angiography was performed 3 to 5 days after surgery. A follow-up angiogram of three fistulas was obtained 2 to 12 weeks later. In one animal, pathologic examination showed occlusion 8 weeks after a successful operations. Eight angiograms of nine fistulas in seven pigs were obtained; one animal died due to cardiac failure. In six pigs, high-flow fistulas were shown to be present, and in two, the fistulas were slow flow; a pseudoaneurysm was seen in one. A follow-up angiogram obtained in three cases showed occlusion of the fistula. Pathologic examination of one animal showed fibrosis in the occluded portion of the fistula. An arteriovenous fistula model was surgically established in 80% of cases; during follow-up, three fistulas were seen to be occluded due to fibrosis. This model can therefore be used within one week of surgery

  12. Spinal dural arteriovenous fistulas

    International Nuclear Information System (INIS)

    The spinal dural arteriovenous fistula (SDAVF) is an important cause of a slowly progressive sensorimotor transverse lesion in mostly elderly patients. The disease affects men in 80% of the cases. Per year and per 1 Million inhabitants only 5-10 new cases of the disease have to be expected. Although rare, the serious disease should not be missed. Diagnosis can be made by MRI and spinal angiography. The result of treatment depends on early diagnosis. The arteriovenous shunt is located within the dural layer of the spinal canal. It connects branches of a radiculomeningeal artery with the veins of the spinal cord. Spinal cord supplying vessels are not primarily involved. Arterialisation of the venous part of the spinal cord circulation results in a chronic congestive myelopathy, which can well be demonstrated by MR imaging. The role of selective spinal angiography is to detect and exactly localize the site of the avshunt, which is rather difficult in some cases. Therapeutic alternatives are effective embolization of the fistula with liquid agents or surgical dysconnection. (orig.)

    International Nuclear Information System (INIS)

    Traumatic subarachnoid-pleural fistulas are rare. The authors found nine cases reported since 1959. Seven have been secondary to trauma and two following thoracotomy. One patient's death is thought to be directly related to the fistula. The diagnosis should be suspected in patients with a pleural effusion and associated vertebral trauma. The diagnosis can usually be confirmed with contrast or radioisotopic myelography. Successful closure of the fistula will usually occur spontaneously with closed tube drainage and antibiotics; occasionally, thoracotomy is necessary to close the rent in the dura

    Sinus of Valsalva aneurysm is a rare condition and associated with a high rate of mortality if rupture occurs. The aneurysms are rarely diagnosed until rupture occurs. This case describes a young Native American female whose only symptom was intermittent chest pain prior to the detection of the aneurysm along with a small ventricular septal defect. The patient was also found to have a coexisting coronary artery fistula, and it is rare phenomenon to have these coexisting anomalies. The anomalies were demonstrated on both cardiac computed tomography and coronary angiography. The patient underwent surgical closure of both anomalies, which is the recommended treatment to avoid future complications. PMID:24804114

    Full Text Available Abstract One of the primary forms of congenital anomalies of the coronary arteries is coronary artery fistula (CAF. It is defined as a direct communication between the coronary artery and any surrounding cardiac chamber or vascular structure, which bypasses the myocardial capillary bed. We present a newborn baby with a large coronary artery fistula connecting the left anterior descending (LAD artery to the left ventricular (LV apex. Associated cardiac abnormalities were found: a ventricular septal defect (diameter 4 mm, a patent foramen ovale as well as trivial tricuspid and mitral regurgitation. Here we demonstrate the echocardiograms of an extremely rare form of CAF diagnosed within the first days of postnatal life.

    Full Text Available Aim. We aimed to identify and describe characteristic and diagnostic ultrasonographic features of arterioportal fistula cases. Patients. In this case series we describe 3 patients with arterioportal fistula. By depending on shared sonographic features of these patients we describe a “sonographic pattern” for the sonographic diagnosis of arterioportal fistula. Conclusion. In summary; both of the artery and vein related with fistula were wider than normal and seen as adjacent anechoic circles, there was an aneurismatic dilation on vein which has turbulent flow within it, the communication between the artery and aneurism can be seen sonographically, both of the vessels have arterial flow, filling of the vein was retrograde and other branches of the artery and vein unrelated with aneurism were all normal in dimension.

    2015-01-01

    To describe the etiology, anatomy and pathophysiology of rectovaginal fistulas(RVFs); and to describe a systematic surgical approach to help achieve optimal outcomes. A current review of the literature was performed to identify the most up-to-date techniques and outcomes for repair of RVFs. RVFs present a difficult problem that is frustrating for patients and surgeons alike. Multiple trips to the operating room are generally needed to resolve the fistula, and the recurrence rate approaches40% when considering all of the surgical options. At present, surgical options range from collagen plugs and endorectal advancement flaps to sphincter repairs or resection with colo-anal reconstruction. There are general principles that will allow the best chance for resolution of the fistula with the least morbidity to the patient. These principles include: resolving the sepsis, identifying the anatomy, starting with least invasive surgical options, and interposing healthy tissue for complex or recurrent fistulas.

    Full Text Available This is a case series and review of the literature adding 11 new cases. Coronary-cameral fistulas (CCFs are infrequent anomalies which are in general co-incidentally found during diagnostic coronary angiography (CAG. To delineate the characteristics of congenital and acquired CCFs in adults, we performed a PubMed search for papers dealing with congenital or acquired CCFs in adults. Publications on coronary-vascular fistulas or paediatric subjects were not included. From the world literature, a total of 243 adult patients were identified who had congenital (65% or acquired (35% CCFs. In this review, which is part one of a two-part series on CCFs, we describe and discuss the congenital fistulas, give an overview on the published literature and report details of our own series of 11 patients with MMFs and solitary macro CCFs. Of the congenital group, 85% were small or large solitary macro CCFs (cut-off 1.5 mm and 15% were coronary artery-ventricular multiple micro-fistulas (MMFs. Apical hypertrophic cardiomyopathy was reported in some of the reviewed subjects with MMFs (3/24 = 13% but not was seen in our own series. Conservative medical management was generally the treatment of choice in congenital MMFs; prophylactic implantable cardioverter defibrillators (ICD were implanted in 2/24 (8% of subjects, especially when extensive micro-fistulisations were involved. None of the patients of our own series required an ICD, as the MMFs were of limited size. Congenital or acquired CCFs in adults are infrequent anomalies having a wide spectrum of clinical presentation may varies from asymptomatic to severely devastating states requiring different treatment modalities.

    Insertion of a voice prosthesis through the tracheoesophageal puncture (TEP) is one way to restore the voice after total laryngectomy. The second generation Provox voice prosthesis is presently one of the most popular devices. Although TEP can be done primarily, there are many centres that prefer it to be done at a second stage for various reasons. However, secondary TEP for retrograde replacement of prosthesis can be difficult and general anaesthesia is very often necessary. Moreover, the pr...

    AIM: To evaluate the management of pancreaticopleu ral fistulas involving early endoscopic instrumentation of the pancreatic duct.METHODS: Eight patients with a spontaneous pancre aticopleural fistula underwent endoscopic retrograde cholangiopancreatography (ERCP) with an intention to stent the site of a ductal disruption as the primary treatment. Imaging features and management were evaluated retrospectively and compared with outcome.RESULTS: In one case, the stent bridged the site of a ductal disruption. The fistula in this patient closed within 3 wk. The main pancreatic duct in this case appeared normal, except for a leak located in the body of the pancreas. In another patient, the papilla of Vater could not be found and cannulation of the pancreatic duct failed. This patient underwent surgical treatment. In the remaining 6 cases, it was impossible to insert a stent into the main pancreatic duct properly so as to cover the site of leakage or traverse a stenosis situated down stream to the fistula. The placement of the stent failedbecause intraductal stones (n = 2) and ductal strictures (n = 2) precluded its passage or the stent was too short to reach the fistula located in the distal part of the pan creas (n = 2). In 3 out of these 6 patients, the pancre aticopleural fistula closed on further medical treatment. In these cases, the main pancreatic duct was normal or only mildly dilated, and there was a leakage at the body/tail of the pancreas. In one of these 3 patients, additional percutaneous drainage of the peripancreatic fluid collections allowed better control of the leakage and facilitated resolution of the fistula. The remaining 3 patients had a tight stenosis of the main pancreatic duct resistible to dilatation and the stent could not be inserted across the stenosis. Subsequent conservative treatment proved unsuccessful in these patients. After a failed therapeutic ERCP, 3 patients in our series devel oped super infection of the pleural or peripancreatic

    Objective: To evaluate the treatment of dural arteriovenous fistula with various methods especially attention for the efficacy. Methods: 32 DAVF patients were treated with transarterial NBCA, GDC, free fibril coils and PVA embolization; also with transvenous coil embolization at the venous tip of the fistula orifice or endovascular stenting, fistula clipping in craniectomy. Results: Five of the 8 cases with DAVF in anterior cranial fossa were cured and 3 improved clinically. Eleven of the 14 patients with DAVF in cavernous region were cured and 3 improved clinically. Among five cases with DAVF in transverse sinus, 2 were cured by transvenous intrasinus embolization and one by sinus isolation; 2 showed improvement after transarterial embolization. Four patients with multiple fistulas of DVAF involving superior sagittal sinus were improved by combined treatment. One patient with DAVF in jugular venous region was treated with multiple sessions of combined methods. Conclusions: Direct clipping is effective in treatment of DAVF in anterior cranial fossa. Transvenous approach is favourable for managing DAVF in transverse sinus and cavernous sinus. Combined endovascular and surgical treatment should be considered for complicated DAVF, focusing on embolization of venous part of the fistulae. (authors)

    Full Text Available Background/ objectives: Branchial arch anomalies form 20% of the congenital head and neck lesions and differ in their management depending on the arch involved. As all these anomalies are managed surgically accurate surgical anatomy is essential as it should be tailored to the lesion involved like it being a cyst, sinus or a fistula. Materials and methods: 11 cases of complete branchial fistula were excised by the combined approach. 6 were females and 5 males, with average age group of 9.09 years and 3 were left sided and 8 right sided. Classical transcervical approach with double incisions at the fistula and hyoid and transoral avulsion of fistula with tonsillectomy done under general anaesthesia in all cases. Results:The average length of the fistula was 7.27 cms. The patients were followed up monthly for six months and later 6 monthly for 2 years. No recurrence were seen on 6-94 months of follow-up with an average follow-up of 43 months. Conclusion:Combined transcervical transoral approach is the conventional procedure of choice for complete branchial fistulas. This approach with no recurrence rates can be made scarless with meticulous tensionless dermal suturing and best skin approximation.

    Full Text Available Aim: The purpose of the study was to observe the outcome of trans-fistula anorectoplasty (TFARP in treating female neonates with anorectovestibular fistula (ARVF. Methods: A prospective study was carried out on female neonates with vestibular fistula, admitted into the surgical department of a tertiary level children hospital during the period from January 2009 to June 2011. TFARP without a covering colostomy was performed for definitive correction in the neonatal period in all. Data regarding demographics, clinical presentation, associated anomalies, preoperative findings, preoperative preparations, operative technique, difficulties faced during surgery, duration of surgery, postoperative course including complications, hospital stay, bowel habits and continence was prospectively compiled and analyzed. Anorectal function was measured by the modified Wingspread scoring as, “excellent”, “good”, “fair” and “poor”. Results: Thirty-nine neonates with vestibular fistula underwent single stage TFARP. Mean operation time was 81 minutes and mean hospital stay was 6 days. Three (7.7% patients suffered vaginal tear during separation from the rectal wall. Two patients (5.1% developed wound infection at neoanal site that resulted in anal stenosis. Eight (20.51% children in the series are more than 3 years of age and are continent; all have attained “excellent” fecal continence score. None had constipation or soiling. Other 31 (79.5% children less than 3 years of age have satisfactory anocutaneous reflex and anal grip on per rectal digital examination, though occasional soiling was observed in 4 patients. Conclusion: Primary repair of ARVF in female neonates by TFARP without dividing the perineum is a feasible procedure with good cosmetic appearance and good anal continence. Separation of the rectum from the posterior wall of vagina is the most delicate step of the operation, takes place under direct vision. It is very important to keep

    8 cases of congenital coronary artery fistula of child age group, diagnosed by cineangiography and confirmed by operation at Seoul National University Hospital in recent 9 years were analysed. The summaries are as follows: 1. The overall incidence was 0.18% of those who underwent cardiac cineangiography (8/4460). 2. Age distribution was from 3 months to 14 years (mean was 5.6 years). Male to female was 4:4. 3. Important physical findings were continuous murmur (7/8) and ischemic change in EKG (3/8). 4. Chest X-ray findings were non-specific but mild cardiomegaly (6/7) and normal pulmonary vascularity (5/7). 5. In cinecardiography, origin of coronary artery fistula was right in 5 case, left in 1 case and single left coronary artery in 1 case. Draining sites were right atrium (3), right ventricle (2), pulmonary artery (1) and left ventricle (1). 6. Associated anomalies were single coronary artery in 1 case, ASD in 1 case and VSD in 1 case. 7. For accurate diagnosis of congenital coronary artery fistula, biplane cineangiography is an essential procedure (Root aortography or selective coronary angiography)

    2016-06-01

    Uroenteric fistulae can occur between any part of the urinary tract and the small and large bowel. Classification is generally based on the organ of origin in the urinary tract and the termination of the fistula in the segment of the gastrointestinal tract. Surgery is often necessary. Congenital fistulae are rare, with most being acquired. Uroenteric fistulae most frequently occur in a setting of inflammatory bowel disease. Imaging often helps in the diagnosis. Management of urinary fistulae includes adequate nutrition, diversion of the urinary tract, diversion of the gastrointestinal tract, treatment of underling inflammatory process or malignancy, and surgery.

    We present the MRI features of a congenital urethroperineal fistula diagnosed in a 12-year-old boy being evaluated after a single urinary tract infection. This diagnosis was initially suggested by voiding cystourethrogram and confirmed by MRI. Imaging revealed an abnormal fluid-filled tract arising from the posterior urethra and tracking to the perineal skin surface that increased in size during micturition. Surgical resection and histopathological evaluation of the abnormal tract confirmed the diagnosis of congenital urethroperineal fistula. MRI played important roles in confirming the diagnosis and assisting surgical planning. (orig.)

    The clinical manifestations of coronary artery anomalies vary in severity, with some anomalies causing severe symptoms and cardiovascular sequelae and others being benign. Cardiovascular computed tomography (CT) has emerged as the standard of reference for identification and characterization of coronary artery anomalies. Therefore, it is important for the reader of cardiovascular CT images to be thoroughly familiar with the spectrum of coronary artery anomalies. Hemodynamically significant anomalies include atresia, origin from the pulmonary artery, interarterial course, and congenital fistula. Non-hemodynamically significant anomalies include duplication; high origin; a prepulmonic, transseptal, or retroaortic course; shepherd's crook right coronary artery; and systemic termination. In general, coronary arteries with an interarterial course are associated with an increased risk of sudden cardiac death. Coronary artery anomalies that result in shunting, including congenital fistula and origin from the pulmonary artery, are also commonly symptomatic and may cause steal of blood from the myocardium. Radiologists should be familiar with each specific variant and its specific constellation of potential implications. PMID:22411942

    The association of congenital tracheal stenosis and tracheoesophageal (TE) fistula is rare. Here, we report 2 patients with tracheobronchial stenosis (complete cartilage ring) involving the lower trachea and right bronchus. Both patients had associated VACTERL (vertebral anomalies, anal atresia, cardiovascular anomalies, TE, renal, and limb defects) congenital cardiac defects and tracheal diverticula after repair of the TE fistula in type C esophageal atresia. The stenotic segment began at the orifice of the TE fistula, which became diverticula after the TE fistula was repaired. Concomitant repair of congenital cardiac defects and a slide tracheoplasty with elimination of the diverticula were performed successfully. PMID:24088476

    2015-10-01

    Full Text Available The paper describes spinal dural arteriovenous fistulas (SDAVF, the most common type of spinal cord vascular anomalies. SDAVFs account for 60–80% of the spinal cord vascular anomalies. The causes of SDAVFs, the specific features of their hemodynamics, and their classification remain the subject matter of disputes.SDAVFs form in dura mater tissue, on the dorsal surface of radicular cuffs. The pathogenesis of neurological disorders in SDAVF has determined the name «venous hypertensive myelopathy», a spinal cord injury occurring in their presence. Pain and paresthesias, cacesthesia (more commonly in their distal parts, and motor disorders as flail legs are observed at the onset of SDAVF in typical cases. On average, 12 to 44 months elapse to establish its diagnosis. In addition of motor and sensory disorders, sphincter impairments and sexual dysfunction are detected in the patients at the time of diagnosis. By this time, most patients have already neurological disability.The paper presents the history of studying SDAVF, the existing classifications of arteriovenous malformations and fistulas, the clinical manifestations of venous hypertensive myelopathy in SDAVF, neuroimaging findings, and treatment options.

    Full Text Available Aim: Postpneumonectomy bronchopleural fistula (PPBPF is a hard-to-treat complication that may develop after pneumonectomy. It follows a persistent course. Although there is no commonly adopted method, closure of the fistula with flaps is the general principle. The use of the omental flap may provide higher success rates in the treatment. Material and Method: PPBPF developed in 12 out of 162 pneumonectomies performed at the department of thoracic surgery between 2011 and 2014. The demographic characteristics, fistula management strategies, morbidity, and mortalities were retrospectively studied by analysis of operative reports and a digital database. Results: The rate of PPBPF was 7.4%. The bronchopleural fistulae could be closed by various treatments in 10 patients; omentopexy constituted the basis of treatment in 8 of them. In the other patients with successful results, resuturing with staplers and vacuum assisted closure were performed during the early period. One of the patients who failed treatment died due to ARDS; therefore, it was not possible to apply all the treatment alternatives. In the other patient, despite the use of all treatment alternatives (eloesser flap, tracheal stent, omentopexy, thoracomyoplasty, vacuum assisted closure, the treatment failed. Discussion: PPBPF is one of the most significant causes of morbidity and mortality in thoracic surgery units. Because its treatment may be long, a good plan and its execution by experienced units are necessary. The omental flap is increasingly popular due to good perfusion. We believe that omentopexy and j type tracheal stent performed by experienced teams will provide successful results in fistula treatment.

    2016-06-01

    Management of complex perineal fistulas such as high perianal, rectovaginal, pouch-vaginal, rectourethral, or pouch-urethral fistulas requires a systematic approach. The first step is to control any sepsis with drainage of abscess and/or seton placement. Patients with large, recurrent, irradiated fistulas benefit from stoma diversion. In patients with Crohn's disease, it is essential to induce remission prior to any repair. There are different approaches to repair complex fistulas, from local repairs to transperineal and transabdominal approaches. Simpler fistulas are amenable to local repair. More complex fistulas, such as those secondary to irradiation, require interposition of healthy, well-vascularized tissue. The most common flap used for this treatment is the gracilis muscle with good outcomes reported. Once healing is confirmed by imaging and endoscopy, the stoma is reversed. PMID:27247533

    Full Text Available Emphysematous prostatic abscess is a rare but relatively serious infectious disease, and its association with rectoprostatic fistula is extremely unusual. The reported risk factors for this condition include diabetes mellitus, immunosuppression, and prostate surgery. We report a rare case of emphysematous prostatic abscess successfully treated by transurethral drainage. Nonetheless, a rectoprostatic fistula was found postoperatively. The fistula healed spontaneously without fasting or fecal diversion after suprapubic cystostomy and placement of a urethral catheter. This case highlights the importance of surgical drainage for the treatment of an emphysematous prostatic abscess and that conservative treatment can be a safe and effective approach for an associated rectoprostatic fistula.

    2010-01-01

    Full Text Available Introduction Choledochoduodenal fistulas are very rare and in most cases are caused by a long-lasting and poorly treated chronic duodenal ulcer. They may be asymptomatic or followed by symptoms of ulcer disease, by attacks of cholangitis or bleeding or vomiting in cases of ductoduodenal stenosis. The diagnosis is simple and safe, however treatment is still controversial. If surgery is the choice of treatment, local findings should be taken into consideration. As a rule, intervention involving closure of fistula is not recommended. Case Outline The authors present a 60-year-old woman with a long history of ulcer disease who developed attacks of cholangitis over the last three years. Ultrasonography and CT showed masive pneumobilia due to a choledochoduodenal fistula. . As there was no duodenal stenosis or bleeding, at operation the common bile duct was transected and end-to-side choledochojejunostomy was performed using a Roux-en Y jejunal limb. From the common bile duct, multiple foreign bodies of herbal origin causing biliary obstruction and cholangitis were removed. After uneventful recovery the patient stayed symptom free for four years now. Conclusion The performed operation was a simple and good surgical solution which resulted in complication-free and rapid recovery with a long-term good outcome. .

    Full Text Available Abstract Background Little has been reported about the impact of tracheoesophageal (TE speech on individuals in the Middle East where the procedure has been gaining in popularity. After total laryngectomy, individuals in Europe and North America have rated their quality of life as being lower than non-laryngectomized individuals. The purpose of this study was to evaluate changes in quality of life and degree of voice handicap reported by laryngectomized speakers from Jordan before and after establishment of TE speech. Methods Twelve male Jordanian laryngectomees completed the University of Michigan Head & Neck Quality of Life instrument and the Voice Handicap Index pre- and post-TE puncture. Results All subjects showed significant improvements in their quality of life following successful prosthetic voice restoration. In addition, voice handicap scores were significantly reduced from pre- to post-TE puncture. Conclusion Tracheoesophageal speech significantly improved the quality of life and limited the voice handicap imposed by total laryngectomy. This method of voice restoration has been used for a number of years in other countries and now appears to be a viable alternative within Jordan.

  17. Ventriculomegaly with non-CNS anomalies

    International Nuclear Information System (INIS)

    We correlated fetal magnetic resonance (MR) imaging findings with postnatal clinical findings to assess ventriculomegaly with non-CNS anomalies. From 2002 to 2010, 52 fetuses underwent a MRI for evaluation of ventriculomegaly after ultrasonography (US). Ten of the 52 demonstrated anomalies outside the central nervous system (CNS), including trisomy 8, trisomy 18, X-linked hydrocephalus, CHARGE/Potter sequences, VATER association, oral-facial-digital syndrome, esophageal atresia type C, or external auditory canal stenosis. Examinations were performed between 24 and 35 weeks' gestation. MR imaging was performed in a 1.5-tesla unit using a phased-array coil without preparation. Fetal MR imaging showed abnormalities of the kidney, bladder, duodenum, and thumbs but did not permit diagnosis of esophageal atresia type C or craniofacial, anorectal, or skeletal anomalies. Cardiac anomaly was most frequent, but fetal MR imaging did not allow final diagnosis of congenital heart disease. On both US and MR imaging, esophageal atresia type C and anorectal anomaly were undetected; normal rectal signal in a case of anorectal anomaly without urorectal fistula did not lead to suspicion of anomaly. Observation of adducted thumbs on MR imaging is an important sign of X-linked hydrocephalus. The slice area used in this study did not cover polydactyly, which accompanies oral-facial-digital syndrome. US and MR imaging are complementary imaging methods used to evaluate ventriculomegaly. Fetal MR imaging should cover the kidney, bladder, and fingers. Further work is needed to determine the anomalies that can be clearly detected by fetal MR imaging. (author)

    Full Text Available Aortoesophageal fistulae (AEF are rare and are associated with very high mortality. Foreign body ingestions remain the commonest cause of AEF seen in children. However in a clinical setting of tuberculosis and massive upper GI bleed, an AEF secondary to tuberculosis should be kept in mind. An early strong clinical suspicion with good quality imaging and endoscopic evaluation and timely aggressive surgical intervention helps offer the best possible management for this life threatening disorder. Our case is a 10-year-old boy who presented to the pediatric emergency with massive bouts of haemetemesis and was investigated and managed by multidisciplinary team effort in the emergency setting.

    Wright, Jeremy; Ayenachew, Fekade; Ballard, Karen D

    2016-01-01

    Objective To examine the incidence and type of obstetric fistula presenting to Hamlin Fistula Ethiopia over a 4-year period. Study design This is a 4-year retrospective survey of obstetric fistula treated at three Hamlin Fistula Hospitals in Ethiopia, where approximately half of all women in the country are treated. The operation logbook was reviewed to identify all new cases of obstetric fistula presenting from 2011 to 2015. New cases of urinary fistula were classified by fistula type (high or low), age, and parity of the woman. Results In total, 2,593 new cases of urinary fistulae were identified in the study period. The number of new cases fell by 20% per year over the 4 years (P<0.001). A total of 1,845 cases (71.1%) were low (ischemic) fistulae, and 804 cases (43.6%) of these had an extreme form of low circumferential fistula. A total of 638 (24.6%) women had a high bladder fistula, which predominantly occurs following surgery, specifically cesarean section or emergency hysterectomy, and 110 (4.2%) women had a ureteric fistula. The incidence of high fistulae increased over the study period from 26.9% to 36.2% (P<0.001). A greater proportion of multiparous women had a high bladder fistula (70.3%) compared with primigravid women (29.7%) (P<0.001). Conversely, a greater proportion of primiparous women experienced a low circumferential fistulae (68.6%) compared with multiparous women (31.4%) (P<0.001). Conclusion There appears to be a decline in the number of Ethiopian women being treated for new obstetric urinary fistulae. However, the type of fistula being presented for treatment is changing, with a rise in high fistulae that very likely occurred following cesarean section and a decline in the classic low fistulae that arise following obstructed childbirth.

  16. A Minimally Invasive Approach for Postoperative Pancreatic Fistula

    International Nuclear Information System (INIS)

    Pancreas fistula is a well-known and severe complication of pancreaticoduodenectomy. It is difficult to control with conservative therapy, inducing further complications and severe morbidity. Until now, re-operation has been the only way to resolve pancreatic fistula causing complete dehiscence of the pancreatic-enteric anastomosis (complete pancreatic fistula). Percutaneous transgastric fistula drainage is one of the treatments for pancreatic fistula. This procedure allows both pancreas juice drainage and anastomosis re-construction at the same time. This is effective and minimally invasive but difficult to adapt to a long or complicated fistula. In particular, dilatation of the main pancreatic duct is indispensable. This paper reports the successful resolution of a postoperative pancreatic fistula by a two-way-approach percutaneous transgastric fistula drainage procedure. Using a snare catheter from the fistula and a flexible guidewire from the transgastric puncture needle, it can be performed either with or without main pancreatic duct dilatation

    Full Text Available Introduction: First branchial cleft anomalies manifest with duplication of the external auditory canal.   Case Report: This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a sinus in the helical root, may explain this feature. A canal wall down mastoidectomy with canaloplasty and wide meatoplasty was performed. The branchial cleft was excised through parotidectomy and facial nerve dissection.   Conclusion:  It should be considered that canal stenosis in such cases can induce cholesteatoma formation in the auditory canal and middle ear.

    Full Text Available Context Pancreaticobronchial fistula is a rare complication of severe pancreatitis. Various diagnostic methods have been described previously. Case report The presentation, diagnostic methods, management and 5-year follow-up of a 40-year-old woman with severe gallstone induced pancreatitis complicated by a pancreaticobronchial fistula were reviewed. Diagnosis was made on the endotracheal intubation when amylase rich-fluid was drained via the tube and confirmed by CT scanning. Successful management was achieved by an open pancreatic necrosectomy, during which air bubbles were seen emerging from the pancreatic collection which supported the diagnosis of the fistula. Five-year follow-up did not reveal any complications. Conclusions Pancreaticobronchial fistulas have the potential to cause severe respiratory complications and mortality. Awareness of this condition is important in the treatment of complicated cases of pancreatitis.

  7. Modified prosthesis for the treatment of malignant esophagotracheal fistula

    International Nuclear Information System (INIS)

    Esophagotracheal fistula is usually a sequela of irradiation or laser treatment of advanced carcinoma of the esophagus or the tracheobronchial tree. Resection of the tumor in these cases is not possible, and palliative bypass surgery is highly risky. The peroral placement of a prosthesis is less invasive, but conventional prostheses often fail to occlude the fistula. The authors regularly use an endoscopic multiple-diameter bougie for dilation. After dilation, a specially designed prosthesis is pushed through the tumor stenosis to block the fistula. This procedure can be done without general anesthesia. The funnels of conventional prostheses cannot cover the fistula when there is either a wide, proximal esophagus above the fistula or a high fistula. To cope with this particular situation, a special fistula funnel was developed. It perfectly occludes the fistulas in all patients. Of 21 patients, 19 were discharged without further aspiration

    Arteriovenous fistulae of the cavernous sinus are rare and difficult to diagnose. They are classified into dural cavernous sinus fistulae or direct carotid-cavernous fistulae. Despite the similarity of symptoms between both types, a precise diagnosis is essential since the treatment is specific for each type of fistula. Imaging findings are remarkably similar in both dural cavernous sinus fistulae and carotid-cavernous fistulae, but it is possible to differentiate one type from the other. Amongst the available imaging methods (Doppler ultrasonography, computed tomography, magnetic resonance imaging and digital subtraction angiography), angiography is considered the gold standard for the diagnosis and classification of cavernous sinus arteriovenous fistulae. The present essay is aimed at didactically presenting the classification and imaging findings of cavernous sinus arteriovenous fistulae. (author)

  10. Endovascular Management of Acute Bleeding Arterioenteric Fistulas

    International Nuclear Information System (INIS)

    The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair. Four presented primary arterioenteric fistulas, and one presented a secondary aortoenteric fistula. All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascular management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean follow-up time was 3 months (range, 1-6 months). All massive bleeding was controlled by occlusive balloon catheters. Four fistulas were successfully sealed with stent-grafts, resulting in a technical success rate of 80%. One patient was circulatory stabilized by endovascular management but needed immediate further open surgery. There were no procedure-related major complications. Mean hospital stay after the initial endovascular intervention was 19 days. Rebleeding occurred in four patients (80%) after a free interval of 2 weeks or longer. During the follow-up period three patients needed reintervention. The in-hospital mortality was 20% and the 30-day mortality was 40%. The midterm outcome was poor, due to comorbidities or rebleeding, with a mortality of 80% within 6 months. In conclusion, endovascular repair is an efficient and safe method to stabilize patients with life-threatening bleeding arterioenteric fistulas in the emergent episode. However, in this group of patients with severe comorbidities, the risk of rebleeding is high and further intervention must be considered

    Broncho-pleural fistula (BPF) and esophago-pleural fistula (EPF) after pulmonary resection are challenging to manage. BPF is controlled by irrigation and sterilization, but such therapy is not sufficient to promote closure of EPF, which usually requires surgical management. However, it is generally difficult to select an appropriate surgical method for closure of BPF and EPF. Here, we report a case of concomitant BPF and EPF after left completion pneumonectomy, in which both fistulas were closed through a right thoracotomy. PMID:27066439

    Full Text Available Liquoric fistula (LF is defined as the communication of the subarachnoid space with the external environment, which main complication is the development of infection in the central nervous system. We reported the case of a patient with non-traumatic eyelid liquoric fistula secondary to orbital meningocele (congenital lesion, which main clinical manifestation was unilateral eyelid edema. Her symptoms and clinical signs appeared in adulthood, which is uncommon. The patient received surgical treatment, with complete resolution of the eyelid swelling. In conclusion, eyelid cerebrospinal fluid (CSF fistula is a rare condition but with great potential deleterious to the patient. It should be considered in the differential diagnosis of unilateral eyelid edema, and surgical treatment is almost always mandatory.

    Deep water corals are an understudied yet biologically important and fragile ecosystem under threat from recent increasing temperatures and high carbon dioxide emissions. Using 454 sequencing, we develop 14 new microsatellite markers for the deep water coral Eguchipsammia fistula, collected from the Red Sea but found in deep water coral ecosystems globally. We tested these microsatellite primers on 26 samples of this coral collected from a single population. Results show that these corals are highly clonal within this population stemming from a high level of asexual reproduction. Mitochondrial studies back up microsatellite findings of high levels of genetic similarity. CO1, ND1 and ATP6 mitochondrial sequences of E. fistula and 11 other coral species were used to build phylogenetic trees which grouped E. fistula with shallow water coral Porites rather than deep sea L. Petusa.

    2016-01-01

    Full Text Available Extra-abdominal complications of pancreatitis such as pancreaticopleural fistulae are rare. A pancreaticopleural fistula occurs when inflammation of the pancreas and pancreatic ductal disruption lead to leakage of secretions through a fistulous tract into the thorax. The underlying aetiology in the majority of cases is alcohol-induced chronic pancreatitis. The diagnosis is often delayed given that the majority of patients present with pulmonary symptoms and frequently have large, persistent pleural effusions. The diagnosis is confirmed through imaging and the detection of significantly elevated amylase levels in the pleural exudate. Treatment options include somatostatin analogues, thoracocentesis, endoscopic retrograde cholangiopancreatography (ERCP with pancreatic duct stenting, and surgery. The authors present a case of pancreatic pseudocyst pleural fistula in a woman with gallstone pancreatitis presenting with recurrent pneumonias and bilateral pleural effusions.

    International Nuclear Information System (INIS)

    Objectives: To evaluate the outcome of trans-vaginal repair of vesico-vaginal fistula through vaginal approach. Study Design: Prospective study. Material and Methods: This study was carried out in Department of Urology, Shaikh Zayed Postgraduate Medical Institute and National institute of Kidney Diseases, Lahore for the period extending from April 2009 to April 2014. Total 17 patients were included in the study. History, physical examination and findings on investigations were reviewed. In all patients cystoscopy and vaginal examination was performed to see fistula site and ureteral orfices. Then trans-vaginal repair was done in all cases. Results: VVF repair was performed on 17 patients aging 25 to 45 years (mean 35.83 ± 7.37 years). The symptoms preceded for a period of 3 months to 8 years. The cause was gynecological hysterectomy 8 (47.05%), obstetric C-section 7 (41.17%) and obstructed labor 2(11.76%). In three of our patients VVF was previously repaired trans-abdominally. On cystoscopy no patients had more than one fistula. In two (11.76%) patients fistula was supratrigonal. The average size of fistula was 2.05 em, detail of fistula site and size is given in table. One patient had leakage on second postop day that was managed with change of Foleys catheter. Successful repair was achieved in all patients and no patient required second attempt. No ureteric injury and other complications were observed. Conclusion: Trans-vaginal repair of VVF avoid laparotomy and bladder bisection. It has reduced hospital stay and morbidity. (author)

    It is here reported on the importance of the integration of data obtained from digital coronary angiography and stress/rest 99mTc sestamibi myocardial perfusion single photon emission tomography in evaluationing the hemodynamic significance of coronary arteriovenous fistulae. Coronary fistulae were detected with coronary angiography in 9 patients. All patients underwent clinical examination, trans thoracic echocardiography, stress electrocardiogram and stress/rest 99mTc sestamibi myocardial perfusion single photon emission tomography. Stress/rest 99mTc sestamibi myocardial perfusion single photon tomography and stress electrocardiogram showed stress-induced myocardial ischemia in 2 patients. The first patient with familial predisposition and risk factors for ischemic heart disease presented a mesocardic heart murmur on clinical examination. At stress ECG (125 Watt, 153 b/m max frequency 93%, arterial pressure 230 mmHg, max frequency pressure product 35200) ischemic alterations were recorded at the first minute of the second stage of the Bruce protocol. Coronary angiography detected a circumflex artery fistula in the coronary sinus. Stress/rest 99mTc sestamibi myocardial perfusion single photon emission tomography for the evaluation of stress/rest perfusion detected a reversible perfusion defect of the proximal portion of the posterolateral and lateral walls, thus confirming the hemodynamic importance of the flow through the fistula during stress cycloergometric testing. In the second patient familial predisposition to ischemic heart disease and previous inferior wall myocardial infarction and non-significant stress ECG, coronary angiography identified a seclusive stenosis of the right coronary artery and anomaly between the anterior interventricular artery and the left pulmonary artery. The presence of the contrast medium in the left pulmonary artery identified a flow from the left ventricle to the left pulmonary artery. Good angiographic results were obtained

    Full Text Available Carotico - cavernous fistula represent abnormal communication between the carotid circulation and the cavernous sinus. They can be classified as direct or indirect which are separate conditions with different aetiologies. Direct Carotico - cavernous fistulas ( CCFs are often secondary to trauma, and as such the demographics reflect the distribution of head trauma, most commonly seen in the young male patients. Presentation is acute and symptoms develop rapidly. In contrast, indirect CCFs have a predilection for the postmenopausal female patient a nd the onset of symptoms is often insiduous. Other conditions that predispose to increased risk include . Ehlers - Danlos syndrome . Fibromuscular dysplasia .

    Full Text Available ABSTRACT Objective: The purpose of this video is to present the laparoscopic repair of a VUF in a 42-year-old woman, with gross hematuria, in the immediate postoperative phase following a cesarean delivery. The obstetric team implemented conservative management, including Foley catheter insertion, for 2 weeks. She subsequently developed intermittent hematuria and cystitis. The urology team was consulted 15 days after cesarean delivery. Cystoscopy indicated an ulcerated lesion in the bladder dome of approximately 1.0cm in size. Hysterosalpingography and a pelvic computed tomography scan indicated a fistula. Materials and Methods: Laparoscopic repair was performed 30 days after the cesarean delivery. The patient was placed in the lithotomy position while also in an extreme Trendelenburg position. Pneumoperitoneum was established using a Veress needle in the midline infra-umbilical region, and a primary 11-mm port was inserted. Another 11-mm port was inserted exactly between the left superior iliac spine and the umbilicus. Two other 5-mm ports were established under laparoscopic guidance in the iliac fossa on both sides. The omental adhesions in the pelvis were carefully released and the peritoneum between the bladder and uterus was incised via cautery. Limited cystotomy was performed, and the specific sites of the fistula and the ureteral meatus were identified; thereafter, the posterior bladder wall was adequately mobilized away from the uterus. The uterine rent was then closed using single 3/0Vicryl sutures and two-layer watertight closure of the urinary bladder was achieved by using 3/0Vicryl sutures. An omental flap was mobilized and inserted between the uterus and the urinary bladder, and was fixed using two 3/0Vicryl sutures, followed by tube drain insertion. Results: The operative time was 140 min, whereas the blood loss was 100ml. The patient was discharged 3 days after surgery, and the catheter was removed 12 days after surgery

    Full Text Available A communication between the coronary and pulmonary arteries, so called coronary to pulmonary fistula, is a rare source of pulmonary supply in pulmonary atresia (PA with ventricular septal defect (VSD. A 4 year old girl referred to National Cardiovascular Center Harapan Kita, Jakarta with symptoms and signs of increased pulmonary blood flow since infancy and was confirmed by the chest x-rays. Heart examination revealed normal first heart sound with single loud second heart sound and an ejection systolic murmur at the pulmonary area. ECG demonstrated sinus rhythm with normal axis and biventricular hypertrophy. Echocardiography was performed and truncus arteriosus (TA type I was suspected with perimembranus VSD, overriding of the aorta, and dilated main pulmonary artery. But on cardiac catheterization studies, a non obstructive fistula was found between the left coronary and main pulmonary artery coexisted with PA and VSD. A successful surgery was performed subsequently and confirmed the above diagnosis. Although there were episodes of pulmonary hypertension crisis during early post operative course, she was then discharge from the hospital in a good condition. Since irreversible pulmonary vascular disease may develop in a non restrictive coronary to pulmonary fistula, early recognition of this anomaly is very important for better surgical result.

  8. A comparative study between MRI and DSA on diagnosis of spinal dural arteriovenous fistula

    International Nuclear Information System (INIS)

    Objective: To evaluate and compare the diagnostic validity of MRI and DSA in patient suspected with spinal dural arteriovenous fistula (SDAVF). Methods: A retrospective review on clinical data of 25 cases diagnosed as SDAVF was done to analyze the characteristics of SDAVF on both MRI and DSA. Results: The sagittal or coronal plane of the T2-weighted MRI could best show the extra-spinal vascular abnormalities and secondary anomalies, while the orifices of the SDAVF, feeding arteries, draining veins could be satisfactorily demonstrated on the DSA. Conclusions: The diagnosis of SDAVF can be made in directly on DSA findings, MRI can delineate the extra-spinal vascular abnormalities and secondary anomalies but not the whole picture

    2014-01-01

    Full Text Available Fetal heart failure and hydrops fetalis may occur due to systemic arteriovenous fistula because of increased cardiac output. Arteriovenous fistula of the central nervous system, liver, bone or vascular tumors such as sacrococcygeal teratoma were previously reported to be causes of intrauterine heart failure. However, coronary arteriovenous fistula was not reported as a cause of fetal heart failure previously. It is a rare pathology comprising 0.2–0.4% of all congenital heart diseases even during postnatal life. Some may remain asymptomatic for many years and diagnosed by auscultation of a continuous murmur during a routine examination, while a larger fistulous coronary artery opening to a low pressure cardiac chamber may cause ischemia of the affected myocardial region due to steal phenomenon and may present with cardiomyopathy or congestive heart failure during childhood. We herein report a neonate with coronary arteriovenous fistula between the left main coronary artery and the right ventricular apex, who presented with hydrops fetalis during the third trimester of pregnancy.

    We study the effect of conformal anomalies on the hydrodynamic description of conformal field theories in four spacetime dimensions. We consider equilibrium curved backgrounds characterized by a time-like Killing vector and construct a local low energy effective action that captures the conformal anomalies. Using as a special background the Rindler spacetime we derive a formula for the effect of the anomaly on the hydrodynamic pressure.

    We report our experience in using Guglielmi electrolytically detachable coils (GDC) alone or in combination with other materials in the treatment of intracranial or cervical high-flow fistulae. We treated 14 patients with arteriovenous fistulae on brain-supplying vessels - three involving the external carotid or the vertebral artery, five the cavernous sinus and six the dural sinuses - by endovascular occlusion using electrolytically detachable platinum coils. The fistula was caused by trauma in six cases. In one case Ehlers-Danlos syndrome was the underlying disease, and in the remaining seven cases no aetiology could be found. Fistulae of the external carotid and vertebral arteries and caroticocavernous fistulae were reached via the transarterial route, while in all dural fistulae a combined transarterial-transvenous approach was chosen. All fistulae were treated using electrolytically detachable coils. While small fistulae could be occluded with electrolytically detachable coils alone, large fistulae were treated by using coils to build a stable basket for other types of coil or balloons. In 11 of the 14 patients, endovascular treatment resulted in complete occlusion of the fistula; in the remaining three occlusion was subtotal. Symptoms and signs were completely abolished by this treatment in 12 patients and reduced in 2. On clinical and neuroradiological follow-up (mean 16 months) no reappearance of symptoms was recorded.

    Full Text Available The arteriovenous fistula (AVF is the most frequent form of vascular access for patients undergoing haemodialysis because it ensures good quality of dialysis and reduce haemodialysis mortality. For this reason, the nephrology nurse plays an important role in the appropriate care of fistula with a view to promoting the longevity and prevention of complications. Purpose: The purpose of this review was to investigate the role of Nephrology nurse in the appropriate care of fistula, promoting longevity and reducing complications, based on scientific data and international guidelines. Material-Method: The methodology followed in this review relied on literatures reviews and investigative studies, which were carried out during the period 2000-2012 and international (Medline, PubMed, Cinahl and Greek databases (Iatrotek on the care and management of fistula in people undergoing chronic haemodialysis. Key-words were used: Arteriovenous fistula, cannulation techniques fistula, guidelines, vascular access, role of nurse. Results: The arteriovenous fistula (AVF is the life line for patients undergoing haemodialysis. For this reason, the appropriate care of fistula and its maintenance in a good condition plays an important role for patient΄s life. Conclusions: Nephrology nurse has a major role in the proper management of the fistula and the education of the patient. Additionally, there is a need for cooperation between all the members of the multidisciplinary team, which includes dialysis nurse, nefrologist, access surgeon, and radiologist, for the broader assessment of fistula and the prevention and timely treatment of any complications.

  5. Ectopic Molar with Maxillary Sinus Drainage Obstruction and Oroantral Fistula

    Full Text Available Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process.   Case report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected.   Discussions: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms.

    A conservation law is one of the most fundamental properties in nature, but a certain class of conservation “laws” could be spoiled by intrinsic quantum mechanical effects, so-called quantum anomalies. Profound properties of the anomalies have deepened our understanding in quantum many body systems. Here, we investigate quantum anomaly effects in quantum phase transitions between competing orders and striking consequences of their presence. We explicitly calculate topological nature of anomalies of non-linear sigma models (NLSMs) with the Wess-Zumino-Witten (WZW) terms. The non-perturbative nature is directly related with the ’t Hooft anomaly matching condition: anomalies are conserved in renormalization group flow. By applying the matching condition, we show massless excitations are enforced by the anomalies in a whole phase diagram in sharp contrast to the case of the Landau-Ginzburg-Wilson theory which only has massive excitations in symmetric phases. Furthermore, we find non-perturbative criteria to characterize quantum phase transitions between competing orders. For example, in 4D, we show the two competing order parameter theories, CP(1) and the NLSM with WZW, describe different universality class. Physical realizations and experimental implication of the anomalies are also discussed.

    The tentorial artery is often involved in arterial supply to tentorial dural fistulas. The hypertrophied tentorial artery is accessible to embolization, either with glue or with particles. Six patients are presented with tentorial dural fistulas, mainly supplied by the tentorial artery. Two patients presented with intracranial hemorrhage, two with pulsatile tinnitus and one with progressive tetraparesis, and in one patient the tentorial dural fistula was an incidental finding. Different endovascular techniques were used to embolize the tentorial artery in the process of endovascular occlusion of the fistulas. All six tentorial dural fistulas were completely occluded by endovascular techniques, confirmed at follow-up angiography. There were no complications. When direct catheterization of the tentorial artery was possible, glue injection with temporary balloon occlusion of the internal carotid artery at the level of the tentorial artery origin was effective and safe. Different endovascular techniques may be successfully applied to embolize the tentorial artery in the treatment of tentorial dural fistulas. (orig.)

  13. Temporary mushroom like covered stent placement with transnasal esophageal fistula abscess drainage for gastroesophageal anastomotic fistula

    International Nuclear Information System (INIS)

    Objective: To investigate the therapeutic effects on gastroesophageal anastomotic fistula with temporary placing covered stent of mushroom shape and transnasal drainage of gastroesophageal anastomotic abscess. Methods: For 8 patients with gastroesophageal anastomotic fistula, under fluoroscopic guidance, the drainage tube was put into the abscess cavity through nasal cavity and esophageal fistula, then stent was implanted within the esophagus. The abscess cavity was aspirated and esophagogram was taken in suitable time. Retaining the drainage tube about one month and then the stent was withdrawn after one week of the taken out of the former. Results: The drainage of abscess and stent placement was successful. The drainage tube was pulled out during 14-21 days after placement. The stent should be removed within one month. All fistulas were closed up and the abscesses disappeared. Conclusions: It is a safe, efficient, complicationless, non-invasive method to treat gastroesophageal anastomotic fistula with temporary placing covered stent with mushroom shape and drainage of abscess through nasal cavity and esophagus. Temporary mushroom-like covered stent placement with transnasal gastroesophageal anastomotic abscess drainage is a safe efficient, complication-less non-invasive method used interventionally.

    Persistent tracheopharyngeal (TPF) and tracheo-oesophageal (TEF) fistulas after laryngectomy create a therapeutic challenge. The current classification of TPFs and TEFs is based on clinical experience without detailed anatomical information. In this study, casts of TPFs/TEFs were obtained from 16 patients; these were the first steps in manufacturing customised prostheses. Fistulas were classified according to the shape and dimension of the tracheopharyngeal and tracheo-oesophageal silicone casts and prostheses as well as on epithetic requirements. Four different types of fistulas were classified: Type A, a fistula with a straight axis between the neopharynx and oesophagus; Type B, a fistula with a stenosis of the neopharynx but a straight axis; Type C, the axis between the neopharynx and oesophagus is flexed anteriorly; and Type D, neighbouring structures are absent creating a large defect. This classification system might improve the manufacturing processes of customised prostheses in individual cases with challenging tracheopharyngeal and tracheo-oesophageal fistulas. PMID:25178413

    Pelvic fistulae are an abnormal communication among the genitourinary tract, the gastrointestinal tract, and the vagina or perineum. Genital tract fistulae have been described in the medical literature for the past several thousand years. Advancements in both the diagnosis and treatment of vaginal fistulae have been obtained over the past century as surgical interventions have become safer and surgical techniques have improved. The most common cause of fistulae worldwide is obstructed labor. In developed countries, fistulae most commonly occur after benign gynecologic surgery, but obstructed labor, malignancy, radiation exposure, and inflammatory bowel disease can also cause fistulae. Fistulae significantly affect quality of life. Diagnostic studies and radiologic imaging can help aid the diagnosis, but a thorough physical examination is the most important component in the evaluation and diagnosis of a fistula. Temporizing treatments are available to help ease patient suffering until surgical management can be performed. Surgical repairs can be performed using an abdominal, vaginal, or transanal approach. Although technically challenging, surgical repair is usually successful, but closure of the fistula tract does not guarantee continence of urine or feces, because there is often underlying damage to the bowel and bladder.

  6. Dialysis fistula or graft: the role for randomized clinical trials.

    Science.gov (United States)

    Allon, Michael; Lok, Charmaine E

    2010-12-01

    The Fistula First Initiative has strongly encouraged nephrologists, vascular access surgeons, and dialysis units in the United States to make valiant efforts to increase fistula use in the hemodialysis population. Unfortunately, the rigid "fistula first" recommendations are not based on solid, current, evidence-based data and may be harmful to some hemodialysis patients by subjecting them to prolonged catheter dependence with its attendant risks of bacteremia and central vein stenosis. Once they are successfully cannulated for dialysis, fistulas last longer than grafts and require fewer interventions to maintain long-term patency for dialysis. However, fistulas have a much higher primary failure rate than grafts, require more interventions to achieve maturation, and entail longer catheter dependence, thereby leading to more catheter-related complications. Given the tradeoffs between fistulas and grafts, there is equipoise about their relative merits in patients with moderate to high risk of fistula nonmaturation. The time is right for definitive, large, multicenter randomized clinical trials to compare fistulas and grafts in various subsets of chronic kidney disease patients. Until the results of such clinical trials are known, the optimal vascular access for a given patients should be determined by the nephrologist and access surgeon by taking into account (1) whether dialysis has been initiated, (2) the patient's life expectancy, (3) whether the patient has had a previous failed vascular access, and (4) the likelihood of fistula nonmaturation. Careful clinical judgment should optimize vascular access outcomes and minimize prolonged catheter dependence among hemodialysis patients. PMID:21030576

    Extrahepatic arteriovenous fistulas involving the gastroduodenal artery and the portal venous system are rare and almost always a late complication of gastric surgery. Secondary portal hypertension and mesenteric ischemia may provoke abdominal pain, upper and lower gastrointestinal hemorrhage, diarrhea, and weight loss. Until recently, surgical excision has been the therapy of choice with excellent results. The authors report a case of gastroduodenal arterioportal fistula with a rare large interpositioned aneurysm in a cardiopulmonary-compromised patient who was considered a non-surgical candidate. The gastroduodenal arterioportal fistula was occluded endovascularly by means of a detachable balloon. A survey of the literature of this rare type of arterioportal fistula is included. (orig.)

    Stenosis of arteriovenous (A-V) fistulae secondary to neointimal hyperplasia (NIH) compromises dialysis delivery, which worsens patients' quality of life and increases medical costs associated with the maintenance of vascular accesses. In the present study, we evaluated the role of the receptor tyrosine kinase c-Kit in A-V fistula neointima formation. Initially, c-Kit was found in the neointima and adventitia of human brachiobasilic fistulae, whereas it was barely detectable in control veins harvested at the time of access creation. Using the rat A-V fistula model to study venous vascular remodeling, we analyzed the spatial and temporal pattern of c-Kit expression in the fistula wall. Interestingly, c-Kit immunoreactivity increased with time after anastomosis, which concurred with the accumulation of cells in the venous intima. In addition, c-Kit expression in A-V fistulae was positively altered by chronic kidney failure conditions. Both blockade of c-Kit with imatinib mesylate (Gleevec) and inhibition of stem cell factor production with a specific short hairpin RNA prevented NIH in the outflow vein of experimental fistulae. In agreement with these data, impaired c-Kit activity compromised the development of NIH in A-V fistulae created in c-KitW/Wv mutant mice. These results suggest that targeting of the c-Kit signaling pathway may be an effective approach to prevent postoperative NIH in A-V fistulae. PMID:25186298

The underlying cause was an inflammatory disease in 12 cases, a carcinoma in 5 and injury (post-radiation therapy) in 1 case. The fistula was visualized by cystography in 2 cases and enterography in 4. Surgical procedures were cystectomy with enterectomy in 2 cases, partial cystectomy with enterectomy in 3, bladder wall overlay-suture with enterectomy in 6 and enterectomy alone in 4. In 3 cases, colostomy without enterectomy was performed for palliative surgery. In all cases the postoperative course was good and surgical treatment was effective. Surgical procedures varied in each case depending on the etiology and the patient's condition. (author)

    Full Text Available A pancreatic pleural effusion may result from a pancreatopleural fistula. We herein discuss two interesting issues in a similar case report of a pleural effusion caused after splenectomy, which was recently published in the World Journal of Gastroenterology. Pancreatic exudate passes directly through a natural hiatus in the diaphragm or by direct penetration through the dome of the diaphragm from a neighboring subdiaphragmatic collection. The diaphragmatic lymphatic “stomata” does not contribute to the formation of such a pleural effusion, as it is inaccurately mentioned in that report. A strictly conservative approach is recommended in that article as the management of choice. Although this may be an option in selected frail patients, there has been enough accumulative evidence that a pancreaticopleural fistula may be best managed by early endoscopy in order to avoid complications causing prolonged hospitalization.

    We report an unusual case of a pancreatic fistula communicating with an appendicectomy wound. This occurred following an episode of acute haemorrhagic pancreatitis. The patient was initially admitted with signs and symptoms indicating appendicitis and went to theatre for an open appendicectomy. However, this did not resolve his symptoms and a laparotomy was performed the next day revealing haemorrhagic pancreatitis. He endured a stormy post-operative course, the cause of which was found to be an external pancreatic fistula with discharge of amylase-rich fluid from the Lanz incision. A trial of conservative management failed despite multiple percutaneous drainage procedures and treatment with broad-spectrum antibiotics. After a second opinion was sought, it was decided to fit a roux loop anastomosis between the head of the pancreas and the duodenum to divert the fistulous fluid. This procedure was a success and the patient remains well 2 years later. PMID:24964425

    Five cases of dural fistulas of the cavernous sinus are reported. The clinical aspect of this lesion is often misleading in the absence of subjective or objective bruits. The diagnosis is made at angiography which should systematically include the internal and external carotid arteries bilaterally. The goal of this study was to elucidate the great variability of the venous drainage and to correlate it with the clinical symptoms and course. The main problem is to know when and how these fistulas should be treated. Vascular ligatures should not be performed. Therapeutic angiography is the treatment of choice, but should be limited to the following indications: poorly tolerated bruits, severe ophthalmic damage (elevated ocular tension, diminished visual acuity, or oculomotor paralysis), angiographically demonstrated massive arteriovenous shunting, and a high degree of cortical venous reflux. Whatever the indication, the course after embolisation is rarely predictable and in particular the risk of extensive venous thrombosis or recurrence is great.

Cholecystoenteric fistula (CF) is an uncommon complication of the gallbladder disease, which has been one of the reasons for the conversion from LC to open cholecystectomy. Here, we have reported four cases of CF managed successfully by laparoscopic approach without conversion to open cholecystectomy.METHODS: During the 4-year period from 2000 to 2004, the medical records of the four patients with CF treated successfully with laparoscopic management at the Chang Gung Memorial Hospital-Taipei were retrospectively reviewed.RESULTS: The study comprised two male and two female patients with ages ranging from 36 to 74 years (median: 53.5 years). All the four patients had right upper quadrant pain. Two of the four patients were detected with pneumobilia by abdominal ultrasonography.One patient was diagnosed with cholecystocolic fistula preoperatively correctly by endoscopic retrograde cholangiopancreatography and the other one was diagnosed as cholecystoduodenal fistula by magnetic resonance cholangiopancreatography. Correct preoperative diagnosis of CF was made in two of the four patients with 50% preoperative diagnostic rate. All the four patients underwent LC and closure of the fistula was carried out by using Endo-GIA successfully with uneventful postoperative courses. The hospital stay of the four patients ranged from 7 to 10 d (median, 8 d).CONCLUSION: CF is a known complication of chronic gallbladder disease that is traditionally considered as a contraindication to LC. Correct preoperative diagnosis of CF demands high index of suspicion and determines the success of laparoscopic management for the subset of patients. The difficult laparoscopic repair is safe and effective in the experienced hands of laparoscopic surgeons.

    Full Text Available Context The main pancreatic duct can form a fistulous communication with another epithelium in the setting of prolonged inflammation, operative manipulation, or direct trauma. We present a rare complication of a pancreaticoureteral fistula following a trauma nephrectomy. Case report A 17-year-old male who sustained a gunshot wound to the back arrived to our Emergency Room hyopotensive, tachycardic, and with free intraperitoneal fluid on focused assessment sonography for trauma (FAST exam. He was taken to the operating room for an exploratory laporatomy where a left nephrectomy was performed to control active bleeding from the left renal hilum. Significant bleeding was also encountered at the portal venous confluence. After packing and damage control laparotomy, the periportal/pancreatic bleeding was controlled during a second procedure 6 hours later. After one month in the Intensive Care Unit with an open abdomen, a computed tomography (CT scan revealed a fluid collection in the splenic fossa which was drained by catheter. Persistent drainage revealed a high amylase concentration (greater than 50,000 U/L. A fistulogram revealed interruption of the main pancreatic duct, and a fluid collection by the tail of the pancreas that was in communication with the left ureter. The patient’s urine amylase was also elevated. The patient was treated nonoperatively given the healing open abdomen and controlled fistula. He had an otherwise uncomplicated recovery. Conclusions This is the second report of a pancreaticoureteral fistula in the literature. Treatment of this communication should be similar to that of other pancreatic fistulae.

  5. Endovascular treatment for immature autogenous arteriovenous fistula

    International Nuclear Information System (INIS)

    Aim: To evaluate the anatomical causes of maturation failure and to assess clinical outcomes after the causative lesions of immature arteriovenous fistula (AVF) have been corrected by endovascular treatment. Materials and methods: The medical records and radiological data from 141 patients who underwent endovascular treatment for immature AVF were retrospectively reviewed. Clinical outcomes, such as the success rates and the patency rates following the procedure, were included. The variables, including patients' age, gender, co-morbidities, fistula age, fistula type, numbers of lesions, degree of stenosis, presence of accessory veins, were analysed as the potential predictors of primary and secondary patency. Results: Technical and clinical success rates were 95.7% (135 of 141 AVFs) and 86.5% (122 of 141 AVFs), respectively. The primary and secondary patency rates were 71.9% and 82.8% at 1 year, 60.1% and 82.0% at 2 years, and 54.5% and 82.0% at 3 years, respectively. By multivariate analysis using Cox proportional hazards model, stenosis of >90% was the only independent predictor for both the primary and secondary patency rates [hazard ratio (HR) 5.026, 95% confidence interval (CI) 2.47–10.24, p 90% was an independent predictor for both the primary and secondary patency after the treatment

  6. Anomalies on orbifolds

    2001-03-16

    We discuss the form of the chiral anomaly on an S1/Z2 orbifold with chiral boundary conditions. We find that the 4-divergence of the higher-dimensional current evaluated at a given point in the extra dimension is proportional to the probability of finding the chiral zero mode there. Nevertheless the anomaly, appropriately defined as the five dimensional divergence of the current, lives entirely on the orbifold fixed planes and is independent of the shape of the zero mode. Therefore long distance four dimensional anomaly cancellation ensures the consistency of the higher dimensional orbifold theory.

  9. Anomalies and tadpoles

    International Nuclear Information System (INIS)

    We show that massless RR tadpoles in vacuum configurations with open and unoriented strings are always related to anomalies. RR tadpoles arising from sectors of the internal SCFT with non-vanishing Witten index are in one-to-one correspondence with conventional irreducible anomalies. The anomalous content of the remaining RR tadpoles can be disclosed by considering anomalous amplitudes with higher numbers of external legs. We then provide an explicit parametrization of the anomaly polynomial in terms of the boundary reflection coefficients, i.e. one-point functions of massless RR fields on the disk. After factorization of the reducible anomaly, we extract the relevant WZ couplings in the effective lagrangians. (author)

    Analysis of the radio-metric data from Pioneer 10 and 11 spacecrafts has indicated the presence of an unmodeled acceleration starting at 20 AU, which has become known as the Pioneer anomaly. The nature of this acceleration is uncertain. In this paper we give a description of the effect and review some relevant mechanisms proposed to explain the observed anomaly. We also discuss on some future projects to investigate this phenomenon.

    Anomalies in Yang-Mills type gauge theories of gravity are reviewed. Particular attention is paid to the relation between the Dirac spin, the axial current j_5 and the non-covariant gauge spin C. Using diagrammatic techniques, we show that only generalizations of the U(1)- Pontrjagin four--form F^ F= dC arise in the chiral anomaly, even when coupled to gravity. Implications for Ashtekar's canonical approach to quantum gravity are discussed.

    The volume anomaly ΔV/V due to the magnetic energy corresponding to the exchange interactions is experimentally determined for YIG. The experimental values (from 77 K to Tc) agree with the values deduced from the theoretical expression based on the Néel's theories of volume anomaly and of ferrimagnetism. These results are compared with those obtained by other authors on ferromagnetic and antiferromagnetic materials with localized magnetic moments : a reduced curve is obtained.

  20. The Holographic Supercurrent Anomaly

    2004-01-01

    The \\gamma-trace anomaly of supersymmetry current in a supersymmetric gauge theory shares a superconformal anomaly multiplet with the chiral R-symmetry anomaly and the Weyl anomaly, and its holographic reproduction is a valuable test to the AdS/CFT correspondence conjecture. We investigate how the \\gamma-trace anomaly of the supersymmetry current of {\\cal N}=1 four-dimensional supersymmetric gauge theory in an {\\cal N}=1 conformal supergravity background can be extracted out from the ${\\cal N}=2$ gauged supergravity in five dimensions. It is shown that the reproduction of this super-Weyl anomaly originates from the following two facts: First the {\\cal N}=2 bulk supersymmetry transformation converts into {\\cal N}=1 superconformal transformation on the boundary, which consists of {\\cal N}=1 supersymmetry transformation and special conformal supersymmetry (or super-Weyl) transformation; second the supersymmetry variation of the bulk action of five-dimensional gauged supergravity is a total derivative.

    1998-01-01

    We calculate the Weyl anomaly for conformal field theories that can be described via the adS/CFT correspondence. This entails regularizing the gravitational part of the corresponding supergravity action in a manner consistent with general covariance. Up to a constant, the anomaly only depends on the dimension d of the manifold on which the conformal field theory is defined. We present concrete expressions for the anomaly in the physically relevant cases d = 2, 4 and 6. In d = 2 we find for the central charge c = 3 l/ 2 G_N in agreement with considerations based on the asymptotic symmetry algebra of adS_3. In d = 4 the anomaly agrees precisely with that of the corresponding N = 4 superconformal SU(N) gauge theory. The result in d = 6 provides new information for the (0, 2) theory, since its Weyl anomaly has not been computed previously. The anomaly in this case grows as N^3, where N is the number of coincident M5 branes, and it vanishes for a Ricci-flat background.

  2. Stent placement in arteriovenous fistula : an experimental study

    International Nuclear Information System (INIS)

    To determine the efficacy of metallic stents in the treatment of experimentally created carotid-jugular fistulas. Materials and Methods : Carotid-jugular fistulas were constructed surgically in four mongrel swines. Three Wallstents (Schneider, Bulbanch, Switzerland), 6mm in diameter and 23mm in length, and one Nir stent (Boston Scientific Corporation, Boston, U.S.A.), 3-5mm in diameter and 16mm in length, were placedendovascularly across the fistula holes within the carotid artery. Carotid angiography was performed before,immediately after, and 1-3 months after stent placement. Fistula specimens were obtained after final angiography and gross and microscopic examination was performed. Results : Angiography demonstrated decreased flow through the fistula immediately after stent placement. During follow-up, flow through the fistula decreased progressively but complete closure did not occur. Carotid arteries p in which Wallstents were placed were patent throughout the follow-up period. A carotid artery in which a Nir stent was used showed no decreased flow during follow-up angiography lasting two months. Pathologically, a thin layer of endothelium covered the stent wires; there was a transitional zone between the fibrous connective tissue of organizing thrombus, and endothelial proliferation occurred in the overlying fistula hole. Conclusions : Stent placement effectively reduced flow through the fistulas but during the ensuing three months closure did not occur. Occlusion was then progressive.Pathologically, intimal proliferation arose from the organizing thrombus on the surface of the stent mesh

    We describe our experience of treatment for a giant esophageal malignant fistula, which has not been reported previously. A 36-year-old woman who was diagnosed as having massive esophageal small cell carcinoma with metastases was treated with chemoradiotherapy.However, a giant esophagomediastinal fistula appeared due to shrinkage of the massive tumor, and all anti-cancer treatment was suspended. However, chemoradiotherapy was restarted at the request of the patient despite the presence of the fistula. After restarting treatment, the giant esophageal fistula was naturally closed despite intensive chemoradiotherapy, and the patient became able to eat and drink. Although the patient finally died,her QOL and prognosis seemed to be improved by the chemoradiotherapy. Anti-cancer treatment could be safely performed despite the presence of a giant fistula.The giant fistula closed while intensive chemotherapy was administered to the patient. Therefore, the presence of a fistula may not be a contraindication for curative chemoradiotherapy. Completion of treatment with proper management and maintenance of patients would be of benefit to patients with fistula.

    PURPOSE: The purpose of this study was to assess the impact of arteriovenous fistulas combined with varying degrees of stenosis on distal bypass hemodynamics and Doppler spectral parameters. METHODS: In an in vitro flow model bypass stenoses causing 30%, 55%, and 70% diameter reduction were induced...... the systolic pressure drop from 31% to 48% and had significant impact on all waveform parameters. CONCLUSIONS: Distal arteriovenous fistulas enhance pressure loss across stenoses and affect downstream velocity waveform configuration. The presence of a combined fistula and a stenosis mimics the distal...... 10 cm upstream of a fistula with low outflow resistance. Flow and intraluminal pressure were measured proximal to the stenosis and downstream of the fistula. The waveform parameters peak systolic velocity, end-diastolic velocity, pulsatility index, and pulse rise time were determined from midstream...

    Full Text Available Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.

    Full Text Available IntroducationIn a recent Cochrane review the authors concluded that there is an urgent need for well-powered, well-conducted randomized controlled trials comparing various modes of treatment of fistula-in-ano. Ten randomized controlled trials were available for analyses: There were no significant differences in recurrence rates or incontinuence rates in any of the studied comparisons. The following article reviews all studies available for treatment of fistula-in-ano with a fistula plug.Material and MethodsPubMed, Medline, Embase and the Cochrane medical database were searched up to December 2014. 47 articles were relevant for this review.ResultsHealing rates of 50 – 60 % can be expected for treatment of complex anal fistula with a fistula plug, with a plug-extrusion rate of 10 – 20 %. Such results can be achieved not only with plugs made of porcine intestinal submucosa, but also those made of other biological mesh materials, such as acellular dermal matrix. Important technical steps in the performance of a complex anal fistula plug repair need to be followed.SummaryTreatment of a complex fistula-in-ano with a fistula plug is an option with a success rate of 50 – 60 % with low complication rate.

    The objective of this retrospective study was to present the authors' experience on the management of labyrinthine fistula secondary to cholesteatoma. 695 patients, who underwent tympanoplasty for cholesteatoma, in a University Hospital between 1993 and 2013 were reviewed, to select only those with labyrinthine fistulas. 42 patients (6%) had cholesteatoma complicated by fistula of the lateral semicircular canal (LSCC). The following data points were collected: symptoms, pre- and postoperative clinical signs, surgeon, CT scan diagnosis, fistula type, surgical technique, preoperative vestibular function and audiometric outcomes. Most frequent symptoms were unspecific, such as otorrhea, hearing loss and dizziness. However, preoperative high-resolution computed tomography predicted fistula in 88 %. Using the Dornhoffer and Milewski classification, 16 cases (38 %) were identified as stage 1, 22 (52 %) as stage II, and 4 (10 %) as stage III. The choice between open or closed surgical procedure was independent of the type of fistulae. The cholesteatoma matrix was completely removed from the fistula and immediately covered by autogenous material. In eight patients (19 %), the canal was drilled with a diamond burr before sealing with autologous tissue. After surgery, hearing was preserved or improved in 76 % of the patients. There was no statistically significant relationship between the extent of the labyrinthine fistula and the hearing outcome. In conclusion, a complete and nontraumatic removal of the matrix cholesteatoma over the fistula in a one-staged procedure and its sealing with bone dust and fascia temporalis, with sometimes exclusion of the LSCC, is a safe and effective procedure to treat labyrinthine fistula.

    To analyze the adults' coronary artery anomalies revealed by 64-MDCT, we retrospectively analyzed 34 cases of coronary artery anomalies (26 males and 8 females, averagely aged 53. 4 years with a range from 30 to 72 years). Multi-plannar reconstruction (MPR), maximum intensity projection (MIP), surface shadow display (SSD) and volume rendering (VR) were used to demonstrate the anomalous coronary artery. We found 4 cases of RCA from the left coronary sinus, 8 cases with secondary RCA, 1 case with high locations of left main (LM) segments from left sinus of valves, 1 case with LAD originated from main pulmonary artery, 3 cases with separate origin of LAD and LCX. Ten cases with myocardial bridge were shown (9 cases in LAD, 1 case in LCX); coronary fistula was seen in 2 cases (one was RCA-RA fistula, another was LAD-RV fistula), coronary aneurysm was found in 2 cases. Three cases in RCA were short and small. In conclusion, 64-MDCT is a good choice for diagnosing the anomalous coronary artery. PMID:19634659

    Full Text Available Fistula in Ano is a benign treatable lesion of the rectum and the anal canal. Cryptoglandular infection accounts for about 90% of these cases. Majority of the infections are Acute and a minority contributed by chronic low grade infection hence pointing to varying etiologies. The pathogenesis has been attributed to the bursting open of an acute or inadequately treated Anorectal abscess into the peri anal skin. Diagnosis of the condition can be made easily with a good source of light, a proctoscope and a meticulous digital examination. Establishing a cure in this condition is difficult owing to two reasons. Firstly, the site of the infection makes the patient reluctant to subject themselves to examination. Secondly, a significant percent of these diseases persist or recur when appropriate surgery is not done or when the post op care is inadequate. Mostly it affects the young and the middle age group thus affecting productive man hours and quality of life. MATERIALS AND METHODS: All cases of clinically diagnosed Fistulae-in-ano above the age of 12 years, admitted in various surgical units in K.R.

    Full Text Available An arteriovenous fistula secondary to a chalazion is a rare occurrence. It may follow spontaneous necrosis or surgical trauma. Digital subtraction angiography and identification of the arterial feeders combined with direct puncture of the nidus and embolization is recommended, as surgical excision becomes much easier and results in a complete excision of the lesion. Conchal cartilage graft is a useful lining material for reconstruction of the tarsal plate due to its natural curvature. It restores lid integrity and ensures a stable and functional eyelid.

    Full Text Available Laparoscopic Nissen fundoplication is the current standard surgical option for complicated GERD and symptomatic hiatal hernia. Though comparable in safety, short-term efficacy, and patient satisfaction when compared with open operation, laparoscopic Nissen fundoplication has demonstrated shorter hospital stays and recuperative times. Commonly reported complications include gastric or esophageal injury, splenic injury, pneumothorax, bleeding, pneumonia, fever, wound infections, and dysphagia. We present an unusual case of gastropericardial fistula that developed as a late complication of laparoscopic Nissen fundoplication performed 4 years earlier.

    Full Text Available The application detects anomaly in network using techniques like histogram, cloning voting, filtering. To extract anomalous flows, one could build a model describing normal flow characteristics and use the model to identify deviating flows. We can compare flows of packets on network with previous flows, like new flows that were not previously observed or flows with significant increase/decrease in their volume. Identify an anomalous flow that combines and consolidates information from multiple histogram-based anomaly detectors [1] [4] [8]. Compared to other possible approaches. Build a histogram based detector that (i applies histogram cloning[1][4], i.e., maintains multiple randomized histograms to obtain additional views of network traffic[3]; and (ii uses the Kullback-Leibler (KL distance to detect anomalies.

  2. Genito-urinary fistula: a major morbidity in developing countries

    International Nuclear Information System (INIS)

    Uro-genital fistulas, majority of which are vesico-vaginal fistulas (VVF), are a great challenge for women in developing countries. It is commonly caused by prolong obstructed labour and is one of the worst complications of child birth and poor obstetric care. The objective of this descriptive study was to review the cases of genitourinary fistulae so as to understand the magnitude of the problem and its aetiology and to share our experience of surgical repair with other specialists in this field. The study was conducted at Gynaecological Unit-II, Liaquat University Hospital Hyderabad, Pakistan from June 1996 to December 2007. The case records of all patients admitted and managed during study period were reviewed. The information regarding characteristics, risk factors and surgical management was collected. The data was analysed by SPSS and mean, range, standard deviation and percentage were calculated. During the study period, 278 patients with genitourinary fistulae were admitted and managed. The mean age of patients with urinary fistulae was 31.5+-7.5 years, parity was 4.2+-2.8, and duration of labour was 38.4+-6.5 hours. The duration of fistulae ranged from 1 day to 25 years. Obstructed labour 246 (88.4%) was the most common cause of urinary fistulae, followed by gynaecological surgeries mainly hysterectomies 26 (9.35%). The most common type of urinary fistula was vesico-vaginal fistula (VVF) 250 (89.9%). A total of 268 underwent surgery. Almost all 261 (97.3%) urinary fistulae were repaired transvaginally except patients with ureterovaginal and vesico-uterine fistulae. The most common surgical procedure used was layered closure. Martius graft was used in 3 (1.1%) patients, who required creation of new urethra. The success rate following first, second and third attempt was 85%, 91% and 96% respectively. Urogenital fistulae are rarity in developed world, but are frequently encountered problem in developing countries like Pakistan, often resulting from prolonged

    Full Text Available A 13-year-old patient with a complaint of worsening lower abdominal pain during the past 4 months was admitted to the emergency department. An abdominopelvic ultrasound scan revealed a distended uterocervical cavity suggestive of hematometrocolpos. Imperforate hymen was observed on examination of the external genitalia. MRI scan revealed an air-fluid level representing pyometrocolpos within a distended vagina. Posterior vaginal extraperitoneal leakage as the sign of a fistula between the vagina and the rectovaginal space was detected. Although laparoscopic approach was planned, malodorous pus expelled after the insertion of the Veress needle, it was decided to proceed to laparotomy. Pus with peritoneal microabscess formations was observed at laparotomy. The imperforate hymen and TVS were excised vaginally. A more complex anomaly should be suspected in cases with hematometra and concomitant imperforated hymen without any bulging and thorough evaluation using radiological imaging techniques should be performed before surgical approach.

    To evaluate the relevant clinical and radiographical findings for the diagnosis of an arteriovenous fistula after a lumbar discectomy. Five patients with an arteriovenous fistula following a lumbar discectomy were preoperatively diagnosed and treated. We retrospectively evaluated the level of surgery, injured vessels, clinical symptoms, physical findings, and the interval between surgery and treatment. Effective and fast diagnostic methods for determining the presence of a postoperative arteriovenous fistula were evaluated. All of the arteriovenous fistulas resulted from operative injuries of the iliac arteries and veins. They were diagnosed after a mean time of 22 months (range 2 months-4 years) in spite of various symptoms and signs shortly after surgery. The arteriovenous fistulas were confirmed with angiography and were treated by surgery for 3 patients and by insertion of a stent-graft in 2 patients. Postoperative CT angiography showed the complete occlusion of the fistula tract and the normal blood flow. Essential clinical information and radiological examination, especially CT angiography with 3D reconstruction, in necessary to obtain to diagnose an arteriovenous fistula after a lumbar discectomy.

    Full Text Available "nPatients with end stage renal disease need a good vascular access for hemodialysis. Arteriovenous fistula is the method of choice for vascular access in these patients. However, failure of arteriovenous fistula due to thrombosis is a major problem. The aim of this study was to evaluate the effect of the heparin on the patency of the arteriovenous fistula. This prospective interventional case control study was performed from November 2003 through May 2005 in vascular surgery ward in Imam Reza Hospital. All the patients who underwent a surgery in order to perform an arteriovenous fistula in cubital or snuff box areas for the dialysis means were enrolled. They were randomly divided into two groups. The case group (n = 96 received intraoperative heparin whereas the controls (n = 102 did not. Early observation of arteriovenous fistula (immediately after surgery showed patency in 89% of heparin group and in 87% of the control group. The patency rate 2 weeks after the surgery was 85% in heparin group versus 74% in the control group, resulting in a statistically significant difference (P value = 0.046. According to higher patency rate of arteriovenous fistula in 2 weeks following surgery in case group, we recommend intraoperative use of heparin in arteriovenous fistula operations.

The inadequate handling of these it contributes to fateful consequences as the loss of the life or of the function of the extremity. The vascular lesions for firearm constitute one of the main causes with the appearance of arteriovenous fistula. We present the case of a 36 year old masculine patient with antecedents of having hurt 1 year ago by firearm in the root of the left thigh goes to present increase of volume of the extremity and difficulty to the march with sensation of fatigue and gravity. To the physical exam increase of volume of the limb more marked affection was verified in the root of the thigh, in the area related with the bullet impact thrill is felt and blow holosistólico is auscultated. The echo doppler and the tomography with contrast use evidenced the presence of a arteriovenous fistula. With this diagnosis was carried out surgical exploration and repair by means of veins bond for exclusion and interference of ilio-femoral arterial implant of politetrafluoroethylene (PTFE. The postoperative evolution was satisfactory with regression of all the clinical signs.

    Spinal dural arteriovenous fistula (SDAVF) is a rare disease, the etiology of which is not entirely clear. It is the most common vascular malformation of the spinal cord, comprising 60-80 % of the cases. The clinical presentation and imaging findings may be nonspecific and misleading, often mistaking it for other entities like demyelinating or degenerative diseases of the spine.This chapter describes the imaging findings, clinical signs, and symptoms of this disease and also the available treatment options according to the current literature.Angiography is still considered the gold standard for diagnosis; however, MRI/MRA is increasingly used as a screening tool. Modern endovascular techniques are becoming increasingly more effective in treating SDAVF offering a less invasive treatment option; however, they still lag behind surgical success rates which approach 100 %. The outcome of both treatment options is similar if complete obliteration of the fistula is obtained and depends mainly on the severity of neurological dysfunction before treatment.Heightened awareness by radiologists and clinicians to this rare entity is essential to make a timely diagnosis of this treatable disease. A multidisciplinary treatment approach is required in order to make appropriate treatment decisions. PMID:26508408

    To establish the effects of BPC 157 on the healing of rat colovesical fistulas, Wistar Albino male rats were randomly assigned to different groups. BPC 157, a stable gastric pentadecapeptide, has been used in clinical applications-specifically, in ulcerative colitis-and was successful in treating both external and internal fistulas. BPC 157 was provided daily, perorally, in drinking water (10µg/kg, 12ml/rat/day) until sacrifice or, alternatively, 10µg/kg or 10ng/kg intraperitoneally, with the first application at 30min after surgery and the last at 24h before sacrifice. Controls simultaneously received an equivolume of saline (5.0ml/kg ip) or water only (12ml/rat/day). Assessment (i.e., colon and vesical defects, fistula leaking, fecaluria and defecation through the fistula, adhesions and intestinal obstruction as healing processes) took place on days 7, 14 and 28. Control colovesical fistulas regularly exhibited poor healing, with both of the defects persisting; continuous fistula leakage; fecaluria and defecation through the fistula; advanced adhesion formation; and intestinal obstruction. By contrast, BPC 157 given perorally or intraperitoneally and in µg- and ng-regimens rapidly improved the whole presentation, with both colon and vesical defects simultaneously ameliorated and eventually healed. The maximal instilled volume was continuously raised until it reached the values of healthy rats, there were no signs of fecaluria and no defecation through the fistula, there was counteraction of advanced adhesion formation or there was an intestinal obstruction. In conclusion, BPC 157 effects appear to be suited to inducing full healing of colocutaneous fistulas in rats. PMID:26875638

  10. Rerouting of high / recurrent anal fistula without seton

    International Nuclear Information System (INIS)

    Objective: To evaluate a new treatment option in cases of high or complex anal fistulas where either the internal opening could not be outlined or there is recurrence after surgery. Study Design: Quasi Experimental study. Place and Duration of study: This study was carried out in Pakistan Naval Ship Hafeez from Jun 2008 to Aug 2011. Patients and Methods: Thirty seven patients were selected for a rerouting procedure in PNS Hafeez. The selection criteria included patients with a high or a complex fistula who had previous surgery but had recurrence of their condition. Complex fistulas, tuberculous fistulas, fistulas with two or more external openings and patients with a recurrent fistula who subsequently were found to have a low fistula were excluded from the study.The lower part of the tract was dissected, rerouted and brought out through the anal canal. The excess tract was excised and the cut end was sutured with the anal canal mucosa, thus converting an external fistula into an internal one, where the secretions from it can be retained by the external anal sphincter, thus preventing constant soiling. Results: Average age was 37 years. Thirty (81%) patients were males. Follow up period was 6 months. Tuberculosis and malignancies were ruled out. The over all success rate was 86.5%. Conclusion: Rerouting of high or recurrent anal fistulas, though not the ideal procedure, can be a useful option in cases where either the internal opening cannot be found or there has been a failure of conventional procedures. It does not eradicate the problem, but prevents constant uncontrolled discharge, which is the main concern of the patient. (author)

    Abstract Gastrointestinal (GI) fistula is a well-recognized complication of acute pancreatitis (AP). However, it has been reported in limited literature. This study aimed to evaluate the incidence and outcome of GI fistulas in AP patients complicated with infected pancreatic or peripancreatic necrosis (IPN). Between 2010 and 2013 AP patients with IPN who diagnosed with GI fistula in our center were analyzed in this retrospective study. And we also conducted a comparison between patients with and without GI fistula regarding the baseline characteristics and outcomes. Over 4 years, a total of 928 AP patients were admitted into our center, of whom 119 patients with IPN were diagnosed with GI fistula and they developed 160 GI fistulas in total. Colonic fistula found in 72 patients was the most common form of GI fistula followed with duodenal fistula. All duodenal fistulas were managed by nonsurgical management. Ileostomy or colostomy was performed for 44 (61.1%) of 72 colonic fistulas. Twenty-one (29.2%) colonic fistulas were successfully treated by percutaneous drainage or continuous negative pressure irrigation. Mortality of patients with GI fistula did not differ significantly from those without GI fistula (28.6% vs 21.9%, P = 0.22). However, a significantly higher mortality (34.7%) was observed in those with colonic fistula. GI fistula is a common finding in patients of AP with IPN. Most of these fistulas can be successfully managed with different procedures depending on their sites of origin. Colonic fistula is related with higher mortality than those without GI fistula.

  20. Key to successful vesico vaginal fistula repair, an experience of urogenital fistula surgeries and outcome at gynaecological surgical camp 2005

    International Nuclear Information System (INIS)

    Vesico-vaginal fistula is not life threatening medical problem, but the woman face demoralization, social boycott and even divorce and separation. The aetiology of the condition has been changed over the years and in developed countries obstetrical fistula are rare and they are usually result of gynaecological surgeries or radiotherapy. Urogenital fistula surgery doesn't require special or advance technology but needs experienced urogynaecologist with trained team and post operative care which can restore health, hope and sense of dignity to women. This prospective study was carried out to analyze the success rate in patients attending the referral hospital and sent from free gynaecological surgery camps held at interior of Sindh, and included preoperative evaluation for route of surgery, operative techniques and postoperative care. Total 70 patients were admitted from the patients attending the camp. Out of these, 29 patients had uro-genital fistula. Surgical repair of the fistula was done through vaginal route on 27 patients while 2 required abdominal approach. Out of 29 surgical repairs performed, 27 proved successful. Difficult and complicated fistulae need experienced surgeon. Establishment of separate fistula surgery unit along with appropriate care and expertise accounts for the desired results. (author)

    Full Text Available Each year between 50,000 to 100,000 women worldwide are affected by obstetric fistula, a hole in the birth canal. Obstetric fistula is one of the major cause for maternal morbidities and mortality and it has been successfully eradicated in developed nations. Women who experience obstetric fistula suffer constant incontinence, shame, and social segregation. Obstetric fistula is prevalent in African and Asian countries, including India. In India, data has been collected in a large scale survey of district level household survey regarding obstetric fistula and its causes. In this study, efforts are endeavoured to understand the prevalence and causes of obstetric fistula in Assam state, India, where prevalence of obstetric fistula is very high (4.5%. Chi-square test was applied to determine the affecting factors of obstetric fistula. Results showing the socioeconomic status, education, place of residence and age group are important determinants in variation of fistula prevalence among women.

    Foreign body is a rare cause of vesico-vaginal fistula most often reported in developed countries. In developing countries obstructed labor is the commonest cause of fistula. A nulliparous 19-year-old female presented with a 3-week history of a foreign body in the vagina causing urinary incontinence and offensive vaginal discharge. Her guardian allegedly inserted the foreign body after she refused a pre-arranged marriage. A plastic container was removed from the vagina under general anesthesia. A large vesico-vaginal fistula was discovered, which was successfully surgically repaired. We recommend urgent removal of the foreign body, preferably under general anesthesia. However, if the history or physical examination reveals prolonged exposure, repair of the fistula should be delayed to allow for adequate debridement in order to prevent any life-threatening complications.

    Full Text Available Abstract Background Colopleural fistula and fecopneumothorax are very rare complications of Crohn's disease. Fistula formation is frequent in Crohn's disease and occurs in approximately 33% of patients. On the other hand, fistulous communication between the pleural cavity and adjacent organs below the diaphragm is extremely rare. Case presentation We describe the case of 27 year-old female with colopleural fistula as a complication of Crohn's disease. The diagnosis was established with clinical exam, barium enema, chest X-ray, abdominal and chest CT exam. The treatment was surgical. Conclusion Colopleural fistula and fecopneumothorax are rare but life treating complications of Crohn's disease. Surgical treatment is mandatory as soon as the diagnosis is established.

    We report the cases of three patients diagnosed with dural arteriovenous fistula (DAVF) and cortical venous reflux (CVR). All were treated by transarterial endovascular embolization. Residual shunting and cortical venous drainage continued to be present at the end of the treatment procedure, despite the fact that during endovascular embolization glue penetration into the proximal venous component of the fistula had been achieved. Subsequently, follow-up angiography showed total obliteration of the fistulas and absent associated CVR. The fistulas were no longer opacified, and no additional treatment was performed. We demonstrate that residual aggressive DAVF may progress to total thrombosis if strategic deposition of the glue into the venous side has been achieved. Early follow-up angiogram is recommended prior to a planned complementary surgical approach. (orig.)

  9. Intracranial dural arteriovenous fistula with spinal medullary venous drainage

    International Nuclear Information System (INIS)

    We report on a 46-year-old patient in whom an intracranial dural arteriovenous (AV) fistula, supplied by a branch of the ascending pharyngeal artery, drained into spinal veins and produced rapidly progressive symptoms of myelopathy and brainstem dysfunction including respiratory insufficiency. Magnetic resonance imaging studies demonstrated brainstem oedema and dilated veins of the brainstem and spinal cord. Endovascular embolization of the fistula led to good neurological recovery, although the patient had been paraplegic for 24 h prior to embolization. This case demonstrates the MRI characteristics of an intracranial dural AV fistula with spinal drainage and illustrates the importance of early diagnosis and treatment. Even paraplegia may be reversible, if angiography is performed and the fistula treated before ischaemic and gliotic changes become irreversible. (orig.)

    Full Text Available Abstract Aorto-atrial fistulas (AAF are rare but important pathophysiologic conditions of the aorta and have varied presentations such as acute pulmonary edema, chronic heart failure and incidental detection of the fistula. A variety of mechanisms such as aortic dissection, endocarditis with pseudoaneurysm formation, post surgical scenarios or trauma may precipitate the fistula formation. With increasing survival of patients, particularly following complex aortic reconstructive surgeries and redo valve surgeries, recognition of this complication, its clinical features and echocardiographic diagnosis is important. Since physical exam in this condition may be misleading, echocardiography serves as the cornerstone for diagnosis. The case below illustrates aorto-left atrial fistula formation following redo aortic valve surgery with slowly progressive symptoms of heart failure. A brief review of the existing literature of this entity is presented including emphasis on echocardiographic diagnosis and treatment.

  13. Current commutator anomalies and chiral anomalies in the canonical formalism

    International Nuclear Information System (INIS)

    Without recourse to the Bjorken-Johnson-Low (BJL) method, current-current and current-electric-field commutator anomalies are evaluated in chiral gauge theories in two- and four-dimensional spacetime with the help of a gauge covariant regularization method. The results are consistent with previous analyses through the BJL method, and partially confirmed Faddeev's conjecture on the commutator anomalies of the Gauss law constraint operators within the canonical formalism. The chiral anomalies of the current divergence are derived from these commutator anomalies in the Weyl gauge where current-electric-field commutator anomalies play important roles

    Background Fistulas after esophagectomy are a significant cause of morbidity and mortality. Several endoscopic treatments have been attempted, with varying success. An experimental model that could validate new approaches such as cellular therapies is highly desirable. The aim of this study was to create a chronic esophageal enterocutaneous fistula model in order to study future experimental treatment options. Methods Eight pigs (six 35-kg young German and two 50-kg adult Yucatan pigs) were used. Through a left and right cervicotomy, under endoscopic view, 1 (group A, n = 6) or 2 (group B, n = 7) plastic catheters were introduced into the esophagus 30 cm from the dental arches bilaterally and left in place for 1 month. Radiologic and endoscopic fistula tract evaluations were performed at postoperative day (POD; 30) and at sacrifice (POD 45). Results Three fistulas were excluded from the study because of early (POD 5) dislodgment of the catheter, with complete fistula closure. At catheter removal (POD 30), the external orifice was larger in group B (5.2 ± 1.1 mm vs 2.6 ± 0.4 mm) with more severe inflammation (72% vs 33%). At POD 45, the external orifice was closed in all fistulas in group A and in 1/7 in group B. At necropsy, the fistula tract was still present in all animals. Yucatan pigs showed more complex tracts, with a high level of necrosis and substantial fibrotic infiltration. Conclusions In this article, we show a reproducible, safe, and effective technique to create an esophagocutaneous fistula model in a large experimental animal. PMID:26989046

    Full Text Available Abstract: Coronary-Cameral Fistula (CCF is an anomalous connection between a coronary artery and cardiac chamber. Most CCFs are discovered incidentally during angiographic evaluation for coronary vascular disorder. Here, we report a 16-year-old boy with exertional breathlessness for 3 years. There was a continuous murmur at the right para sternal border in the 4th and 5th intercostal space. Echocardiography showed Right Ventricular Hypertrophy (RVH with strain pattern. Besides, transthoracic echocardiography demonstrated a normally functioning left ventricle, but dilated right atrium and ventricle. The right ventricle also showed hypertrophy and trabeculation. Coronary angiography demonstrated a direct connection between the right ventricular cavity and the right epicardial coronary artery. However, the left coronary arterial system was normal. The patient was treated by ligation of the fistulous connection by off-pump surgery.

    Cowden syndrome is a rare autosomal dominant disease. It is characterized by multiple noncancerous tumorlike growths called hamartomas, which typically are found in the skin, oral mucosa, thyroid, breast, and gastrointestinal tract. It carries with it a potential risk of malignant transformation, especially of the breast and thyroid. In 80% of the cases, the human tumor suppressor gene, phosphatase and tensin homolog (PTEN), is mutated in the germ line. We report a patient with Cowden syndrome who presented with generalized seizure and left anterior temporal hemorrhage and a nontraumatic subarachnoid hemorrhage due to multiple intracranial arteriovenous fistulas (AVFs). We discuss previous reports about vascular malformations in patients with Cowden syndrome and PTEN mutations. Importantly, we hypothesize that the production of multiple AVFs in our patient was associated with PTEN mutation. PMID:27105569

    @@ Perimedullary arteriovenous fistula (PMAVF, type Ⅳ spinal cord arteriovenous malformation,SCAVM) is a direct arteriovenous shunt without abnormal vascular connection between the feeding artery and draining vein. Most patients with PMAVF present with a progressive myelopathy caused by venous hypertension, resulting in disabling deficits and incurable complete transverse myelopathy.1'2The lesion is usually located on the surface of the spinal cord or under the pia mater at the level of the conus medullaris or cauda equina, thoracic PMAVF is rarely encountered. Most PMAVFs are fed by the anterior spinal artery (ASA), posterior spinal artery (PSA), or both.1-5 Multiple arterial feeders from the ASA can make the treatment of the disease difficult.6From August 2004 to February 2005, we treated a patient with a recurrent PMAVF (type Ⅳb) at the thoracic level with multiple blood supply.

    Pleural effusions due to pleural injury following supracostal percutaneous nephrolithotomy (PCNL) occur in upwards of 15% of patients; however, these effusions are invariably diagnosed immediately postoperative or during the hospital stay. Herein, we report our initial experience with a delayed nephropleural fistula. A 52-year-old female underwent an uneventful supracostal right PCNL staghorn stone procedure and was discharged on postoperative day 1. She presented to the emergency department 8 days after her original procedure and one day after ureteral stent removal in the office, with right pleural effusion, concomitant contralateral renal colic secondary to migration of a left pelvic stone into her left proximal ureter, and acute renal failure/oliguria. She was treated with right chest tube drainage, bilateral nephrostomy tube placement, and subsequent left holmium laser ureterolithotripsy. PMID:27579431

    Full Text Available Oronasal fistula (ONF is the commonest complication associated with cleft palate surgery. The main symptoms associated with ONF are nasal regurgitation of food matter and hypernasality of voice. Repair of cleft palate under tension is considered to be the main reason of ONF though vascular accidents and infection can also be the cause. Most of the ONFs are situated in the hard palate or at the junction of hard and soft palate. Repair of ONF depends on its site, size and mode of presentation. A whole spectrum of surgical procedures starting from small local flaps to microvascular tissue transfers have been employed for closure of ONF. Recurrence rate of ONF is 25% on an average after the first attempt of repair.

  13. Inoperable aggressive mesenteric fibromatosis with ureteric fistula

    International Nuclear Information System (INIS)

    The purpose of our report is to illustrate an aggressive case of mesenteric fibromatosis in a 17-year-old girl with a ureteric fistula and to review imaging and pathological features, natural history and treatment options of this disease. Our patient underwent computed tomography that revealed a widespread intra-abdominal mass. The necrotic centre of this mass had a fistulous communication with the right ureter. Fibromatoses represent a spectrum of uncommon benign conditions characterised by proliferating fibrous tissue. The deep intra-abdominal form of mesenteric fibromatosis (MF), one of the rare subtypes of the 'fibromatoses' or 'desmoid tumours', grows rapidly and may become extensive. Surgery provides good results in limited disease and non-surgical modalities in cases of unresectable and residual disease

    Radio-metric Doppler tracking data received from the Pioneer 10 and 11 spacecraft from heliocentric distances of 20-70 AU has consistently indicated the presence of a small, anomalous, blue-shifted frequency drift uniformly changing with a rate of ~6 x 10^{-9} Hz/s. Ultimately, the drift was interpreted as a constant sunward deceleration of each particular spacecraft at the level of a_P = (8.74 +/- 1.33) x 10^{-10} m/s^2. This apparent violation of the Newton's gravitational inverse-square law has become known as the Pioneer anomaly; the nature of this anomaly remains unexplained. In this review, we summarize the current knowledge of the physical properties of the discovered effect and the conditions that led to its detection and characterization. We review various mechanisms proposed to explain the anomaly and discuss the current state of efforts to determine its nature. A comprehensive new investigation of the anomalous behavior of the two Pioneers has begun recently. The new efforts rely on the much-extend...

    We present a case of an aortocaval fistula (ACF) without bleeding because a clot was covering the fistula. A 60-year-old man was diagnosed as having a ruptured abdominal aortic aneurysm (AAA) and an aortocaval fistula, by enhanced computed tomography (CT). After the aneurysm had been opened, the fistula was detected, but there was no bleeding because it was covered with clot. After graft repair, bleeding from the fistula occurred when the clot was removed by suction. Direct closure of the fistula was achieved after bleeding was controlled by digital compression.

    Carotid-cavernous fistula (CCF) associated with persistent trigeminal artery (PTA) is a rare but important clinical entity. We present a case treated by microcoil embolization with preservation of internal carotid, PTA, and hasilar artery flow following embolization. A 62-year-old female developed pulsatile tinnitus followed by left eye proptosis and diplopia. Examination revealed a cranial nerve VI palsy and an objective bruit over the left orbit. Angiographic evaluation revealed a carotid cavernous fistula originating from a persistent trigeminal artery. Placement of a detachable balloon across the fistula site while preserving the PTA proved impossible, and the fistula was treated with microcoils following placement of a microcatheter across the fistula into the cavernous sinus. Complete closure of the fistula was followed by resolution of the patient's symptoms. Preservation of all major vessels including the PTA was accomplished through the use of coil embolization. Careful evaluation of the angiogram is necessary to identify PTA associated with a CCF. Previous reports have described treatment of CCF with PTA by surgical or balloon ocolusion, some involving sacrifice of the PTA. Examination of the relevant embryology and anatomy reveals, however, that occlusion of the PTA must be approached with caution due to potential supply to the posterior circulation.

    Objective:To find an effective treatment for advanced cancer patients with esophageal fistula. Methods:From 1998 to 2006, we studied 42 patients with advanced esophageal cancer and 5 lung cancer patients with carcinomatous esophageal fistula(3 females,44 males,aged 29-92 years). Ten patients with both esophageal cancer stricture and fistula were first dilated under endoscope,then a memory stent with a membrane was placed in the esophageal lumen. Others were treated only with a memory stent with a membrane,three of them with a large fistula(diameter>1.5 cm)were treated with bio-protein glue after placement of an esophageal metal stent.Results:The fistulas were covered by a stent and the patients could eat and drink immediately.Their quality of life was improved and their survival was prolonged, 44 out of 47 patients survived for>3 mo. Conclusion:Placement of esophageal stent with membrane or in combination with bio-protein glue through endoscope is an effective method for treating the bronchoesophageal fistula.

  18. Combined endovascular and surgical treatment in vertebral arteriovenous fistula

    International Nuclear Information System (INIS)

    A 7-year-old girl with a right-sided congenital arteriovenous fistula in the neck was admitted with signs of cardial incompensation. Her fistula was fed from the right vertebral artery in antegrade as well as retrograde directions. A steal from the intracranial arteries was established. In addition, smaller feeding arteries from the neck were found. She was operated on with ligation of the right vertebral artery proximal to the fistula but the attempted ligation of the artery cranially to the fistula was unsuccessful. She was therefore embolized by the formation of a plug of platinum fiber coils in the upper right vertebral artery. Catheterization was performed from the left vertebral artery via the basilar artery. Persisting minor feeders to the fistula from cervical arteries were embolized in a second session. Finally, surgical extirpation of the fistula was performed together with the operative ligation of a crossover feeding artery from the left vertebral artery. Her heart size, heart rate and blood pressure were successively normalized. (orig.)

    2011-11-01

    Arteriovenous fistulae are created surgically to provide access for dialysis in patients with renal failure. The current hypothesis is that the rapid remodeling occurring after the fistula creation is in part a process to restore the mechanical stresses to some preferred level (i.e. mechanical homeostasis). Given that nearly 50% of fistulae require an intervention after one year, understanding the altered hemodynamic stress is important in improving clinical outcomes. We perform numerical simulations of four patient-specific models of functioning fistulae reconstructed from 3D Doppler ultrasound scans. Our results show that the vessels are subjected to `normal' shear stresses away from the anastomosis; about 1 Pa in the veins and about 2.5 Pa in the arteries. However, simulations show that part of the anastomoses are consistently subjected to very high shear stress (>10Pa) over the cardiac cycle. These elevated values shear stresses are caused by the transitional flows at the anastomoses including flow separation and quasiperiodic vortex shedding. This suggests that the remodeling process lowers shear stress in the fistula but that it is limited as evidenced by the elevated shear at the anastomoses. This constant insult on the arterialized venous wall may explain the process of late fistula failure in which the dialysis access become occluded after years of use.

    To determine the frequency of oro-nasal fistula in patients undergoing complete cleft palate repair by two flappalatoplasty. Study Design: Case series. Place and Duration of Study: Department of Plastic Surgery, Services Hospital, Lahore, from January to December 2013. Methodology: Patients admitted to the study place for repair of cleft palate after informed consent obtained were included. Cleft palate was repaired by two-flap palatoplasty, using Bardach technique. Patients were discharged on the second postoperative day and followed-up at third week postoperatively. During follow-up visits, fistulae formation and their sites were recorded on pre-designed proforma. Results: Among the total 90 patients, 40 patients (44.4%) were male and 50 patients (55.6%) were female. The mean age was 6.4 +- 5.7 years ranging from 9 months to 20 years. At third week follow-up, 5 patients (5.6%) had fistulae formation. Four patients (80%) had anterior fistulae and one patient (20%) had posterior fistula. Conclusion: With two-flap palatoplasty Bardach procedure for repair of cleft palate, the complication of fistula formation was uncommon at 5.6%, provided the repair was tension free and multi-layered.

    Aortoduodenal fistula is a rare and life-threatening cause of gastrointestinal hemorrhage. The patient was a 44-year-old woman who repeated intermittent hematemesis and melena after hysterectomy, para-aortic lymph node dissection, and subsequent radiotherapy. Angiography revealed no bleeding point. Upper gastrointestinal endoscopy showed an ulcer at the third portion of the duodenum. Emergency laparotomy revealed an aortoduodenal fistula which was inferred to be caused by radiotherapy because no recurrence of malignancy was detected. After the fistula was closed, the patient repeated hematemesis and anal bleeding. She died of acute hemorrhagic shock, in spite of three operations including axillo-femoral bypass. We propose that radiation might have played a role in the pathogenesis of the aortoduodenal fistula in our case. The new case of primary aortoduodenal fistula following radiotherapy is added to four cases previously reported in the literature. Six cases in which the lesion of the duodenum could be demonstrated by endoscopy, have been reported in Japan. Aortoduodenal fistula should be considered as a probable diagnosis in patients presenting massive gastrointestinal hemorrhage after radiotherapy. Rapid surgical treatments are needed, and operative procedures to be considered include resection of the aorta with aortic stump closure and axillo-femoral bypass. (author)

  2. Global anomalies in six dimensions

    International Nuclear Information System (INIS)

    Applying Witten's formula for global gauge and gravitational anomalies to six dimensional supergravities, we find: (a) The perturbatively anomaly free N=4 chiral supergravity coupled to 21 tensor multiplets is global anomaly free for any choice of space-time manifold with vanishing third Betti number (b3). (b) The perturbatively anomaly free matter coupled N=2 chiral supergravities with arbitrary number of tensor multiplets, whose Yang-Mills gauge groups do not include G2, SU(2), or SU(3) are free of global anomalies if the theory is formulated on S6. In the case of 9 tensor multiplets coupled to supergravity this result holds for any spacetime with vanishing b3. (c) The N=6 chiral supergravity has perturbative gravitational anomalies, and therefore the global anomalies need not be considered in this case. (author)

    Similarily as in the Ashtekar approach, the translational Chern-Simons term is, as a generating function, instrumental for a chiral reformulation of simple (N=1) supergravity. After applying the algebraic Cartan relation between spin and torsion, the resulting canonical transformation induces not only decomposition of the gravitational fields into selfdual and antiselfdual modes, but also a splitting of the Rarita-Schwinger fields into their chiral parts in a natural way. In some detail, we also analyze the consequences for axial and chiral anomalies.

    Full Text Available Background: Congenital anomalies of urinary system are common and are found in 3-4% of population, and lethal urinary anomalies account for 10% of termination of pregnancy. Methods: A study was done to know the incidence of congenital anomalies at birth for the period of 4 months from May 99 - Sept 99 at Cheluvamba hospital attached to Mysore medical college. Congenital anomalies in the still births, live births and aborted fetuses >20 weeks were studied along with the case history and ultrasound reports. Aborted fetuses and still born babies were collected for autopsy after the consent of parents. These babies were fixed in 10% formalin and autopsy was done after fixing, and anomalies were noted. Results: Total births during study period were 3000. There were 61 babies with congenital anomalies and 6 babies had anomalies of urinary system. Among the urinary system anomalies 1 baby had bilateral renal agenesis, 1 baby had unilateral renal agenesis with anophthalmia (Fraser syndrome, 2 babies had Multicystic dysplastic kidney disease (MCDK and 1 live baby had hydronephrosis due to obstruction at pelvi ureteric junction, and 1 live female baby had polycystic kidneys. Conclusion: Incidence of urinary system anomalies in the present study was 2 per 1000 births. U/S detection of urinary anomalies varies with period of gestation, amniotic fluid volume and visualisation of urinary bladder. Autopsy helps to detect renal agenesis.

    Pharyngocutaneous fistula is the most common non-fatal complication following total laryngectomy. To start oral feeding and exclude the presence of a pharyngocutaneous fistula, a subjective test and instrumental assessments using videofluoroscopy, have been described. The aim of this study was to evaluate the effectiveness of oral-pharyngo-oesophageal scintigraphy as an objective and non-invasive tool to establish presence, site and dimensions of the fistula. Observations were performed on 3 male patients, mean age 65 years, who underwent total laryngectomy and mono or bilateral neck dissection after failure of radiotherapy in 2 cases and of conservative laryngeal surgery in the third case, complicated by post-operative pharyngocutaneous fistula. Oral-pharyngo-oesophageal scintigraphy dynamic study with sequential images were obtained during the swallowing phases. In case 1, the test showed a wide pharyngocutaneous fistula the internal orifice of which was at the level of the base of the tongue: on the scintigraphic images, the radiomarked water bolus, from the fistulous orifice, descended along the stoma walls and only a small part reached the oesophagus. In the other two patients, the pharyngocutaneous fistula was small and the internal fistulous orifice was detected in the lower part of T-suture line. In conclusion, scintigraphy offered the possibility to precisely identify presence of pharyngocutaneous fistula and location of its internal orifice and to monitor its spontaneous closure. Therefore, important information could be obtained regarding the suture line status and the possibility of deciding whether to remove the nasogastric tube or to leave it in place. Finally, these data showed that oral-pharyngo-oesophageal scintigraphy could be performed in the early post-operative period to optimize starting safe oral feeding. PMID:20162023

    A cholecystocolonic fistula is an uncommon late complication of chronic gallstone disease. Although it may cause acute life-threatening complications such as bowel obstruction or massive hemorrhaging, its accurate preoperative diagnosis may be difficult due to minimal or nonspecific symptoms. Cholecystocolonic fistulas have been diagnosed by various methods, including ERCP. However, the diagnosis of a cholecystocolonic fistula using MRCP has not been reported in the literature. In this case report, we describe a case of a cholecystocolonic fistula detected by MRCP.

    Summary: Residual palatal fistula after repair of palatal cleft is common. Repair of residual oronasal fistula is not always successful. Two-layer closure techniques that close these fistulas with soft tissue are a common practice. Turnover flaps are the most used flaps and often the sole method for nasal-side closure of fistula. Anteriorly based inferior turbinate flap can be used to provide soft tissue for nasal-side closure when turnover flaps will not provide sufficient tissue for this pu...

    This paper investigates Starobinsky's model of inflation driven by the trace anomaly of conformally coupled matter fields. This model does not suffer from the problem of contrived initial conditions that occurs in most models of inflation driven by a scalar field. The universe can be nucleated semiclassically by a cosmological instanton that is much larger than the Planck scale provided there are sufficiently many matter fields. There are two cosmological instantons: the four sphere and a new ``double bubble'' solution. This paper considers a universe nucleated by the four sphere. The AdS/CFT correspondence is used to calculate the correlation function for scalar and tensor metric perturbations during the ensuing de Sitter phase. The analytic structure of the scalar and tensor propagators is discussed in detail. Observational constraints on the model are discussed. Quantum loops of matter fields are shown to strongly suppress short scale metric perturbations, which implies that short distance modifications of gravity would probably not be observable in the cosmic microwave background. This is probably true for any model of inflation provided there are sufficiently many matter fields. This point is illustrated by a comparison of anomaly driven inflation in four dimensions and in a Randall-Sundrum brane-world model.

    Full Text Available Background and Aim: Total laryngectomy following laryngeal cancer has many sequelae , that loss of voice is the most important of them. Tracheoesophageal puncture (TEP and prosthesis insertion has evolved into the most widely used and accepted technique for vocal rehabilitation. Materials and Methods: 10 patients that underwent TEP in Amir Alam and Imam Khomeini hospitals from Feb. 2002 through Nov. 2003; were included in this study. Prosthesis insertion in 4 patients is primary and in 6 patients is secondary; and all patients are men. Results: The age of patients was between 50 to 70. 90% of patients had history of cigarette smoking and 10% of them had history of drinking alcohol. Salivary leakage was seen in 30% of patients that was improved with conservative management. Fluency of speech in 30% of patients and intelligibility of speech & voice quality in 40% of patients is good. Conclusion: We could conclude that TEP has less complication & better speech results of other vocal rehabilitation methods. Carefully selection of patients & size of prosthesis has important role in results of TEP.

    PurposeTo evaluate the usefulness of an approach through the radial artery distal to the arteriovenous anastomosis for salvaging nonmaturing radiocephalic arteriovenous fistulas.MethodsProcedures that fulfilled the following criteria were retrospectively reviewed: (1) autogenous radiocephalic fistulas, (2) fistulas less than 3 months old, (3) distal radial artery approach for salvage. From 2005 to 2011, a total of 51 patients fulfilling the above criteria were enrolled. Outcome variables were obtained from angiographic, clinical and hemodialysis records, including the success, complication, and primary and secondary patency rates.ResultsThe overall anatomical and clinical success rates for the distal radial artery approach were 96 and 94 %, respectively. The average procedure time was 36 {+-} 19 min. Six patients (12 %) experienced minor complications as a result of extravasations. No arterial complication or puncture site complication was noted. The postinterventional 6-month primary patency rate was 51 %, and the 6-month secondary patency rate was 90 %. When the patients were divided into a stenosed group (20 patients) and an occluded group (31 patients), there were no differences in the success rate, complication rate, or primary and secondary patency rates.ConclusionAn approach through the radial artery distal to the arteriovenous anastomosis is an effective and safe alternative for the salvage of nonmaturing radiocephalic arteriovenous fistulas, even for occluded fistulas.

  12. High-resolution MRI for Primary anal fistulas

    International Nuclear Information System (INIS)

    Objective: To evaluate the accuracy and clinical value of preoperative high-resolution magnetic resonance (MR) imaging with a phased-army coil for the detection of anal fistulas. Methods: A total of 20 patients with surgically proved anal fistulas underwent preoperative MR imaging with phased-array coil at 1.5 T MR unit. The imaging protocol included high-resolution T2-weighted turbo spin echo sequence acquisition at axial, sagittal and coronal planes and axial T2-weighted sequence with fat suppression. Results: Twenty patients were found to have 27 fistulas, 24 internal openings, 28 external openings, and 10 perianal abcesses. The sensitivity and specificity for detecting primary fistula tracks, abscesses and internal openings were 92.6% (25/27) and 92.3% (12/13), 100.0% (10/10) and 96.3% (26/27), 91.7% (22/24) and 85.7% (12/14), respectively. Conclusion: High-resolution Mil imaging is a very accurate preoperative technique for evaluating the classification of fistula-in-ano, the course of primary tracks and the presence of abscesses, thus providing important information for proper surgical treatment.

    Background White blood cell count is an important index to the outcome of patients. In hospital, leukopenia is accompanied by high mortality, morbidity and treatment costs. However, in infectious diseases, the reasons responsible for leucopenia was not well elucidated. We investigated patients with gastrointestinal fistula to find risk factors for leukopenia.Methods A prospective case control investigation was carried out in the Gastrointestinal Fistula Center, General Surgical Institute of Jinling Hospital. Cases included gastrointestinal fistula patients with leukopenia (n=98) and controls composed of gastrointestinal fistula patients with normal white blood cell count (n=78). The two groups were compared for risk factors of leucopenia by statistical analysis.Results Factors associated with an increased risk for leukopenia included bacterial infection (25.5%) and hypoalbuminaemia (61.2%). Multivariable Logistic regression analysis identified bacterial infection (80%), urinary catheter (70%) and central vein catheter (60%) as the independent determinants for mortality in cases.Conclusions In patients with gastrointestinal fistula, two independent factors for leukopenia and three significant predictors of mortality were elucidated. We suggest that clinicians give patients more supportive management and apply prevention strategies to treat and prevent leukopenia.

  14. Transitional Flow in an Arteriovenous Fistula: Effect of Wall Distensibility

    2012-11-01

    Arteriovenous fistulae are created surgically to provide adequate access for dialysis in patients with end-stage renal disease. Transitional flow and the subsequent pressure and shear stress fluctuations are thought to be causative in the fistula failure. Since 50% of fistulae require surgical intervention before year one, understanding the altered hemodynamic stresses is an important step toward improving clinical outcomes. We perform numerical simulations of a patient-specific model of a functioning fistula reconstructed from 3D ultrasound scans. Rigid wall simulations and fluid-structure interaction simulations using an in-house finite element solver for the wall deformations were performed and compared. In both the rigid and distensible wall cases, transitional flow is computed in fistula as evidenced by aperiodic high frequency velocity and pressure fluctuations. The spectrum of the fluctuations is much more narrow-banded in the distensible case, however, suggesting a partial stabilizing effect by the vessel elasticity. As a result, the distensible wall simulations predict shear stresses that are systematically 10-30% lower than the rigid cases. We propose a possible mechanism for stabilization involving the phase lag in the fluid work needed to deform the vessel wall. Support from an NIDDK R21 - DK08-1823.

    2016-05-17

    Coronary-cameral fistulas (CCF) are anomalous connections between one or more coronary arteries and a cardiac chamber, most commonly the right ventricle or right atrium. The major indications for closure are: significant left to right shunt, myocardial ischaemia, prevention of endoarteritis or rupture. Nowadays, the first option for treatment is transcatheter closure. According to the morphology of the fistulas the most appropriate occluder device should be selected: coils (e.g., Gianturco coils, controlled-release coils, PFM coils), vascular plugs or a patent ductus arteriosus (PDA) device or muscular ventricular septal defect (VSD) device. The way to deploy the occluders could be direct arterial or venous through an arteriovenous loop, according to the anatomy of the fistulas assessed by multiple angiograms in different projections. A test occlusion of the fistula with balloon catheter and simultaneous coronary angiogram is recommended for choosing the proper device type and size and the best position for deployment to achieve complete occlusion of the fistula without compromising the flow in coronary side branches.

  17. Imaging studies of pyriform sinus fistula

    International Nuclear Information System (INIS)

    Pyriform sinus fistula (PSF) refers to a persistent embryologic third or fourth pharyngeal pouch, which typically presents as a congenital sinus tract that originates from the pyriform sinus. The sinus tract is often diagnosed by a barium study or direct endoscopic inspection. Utilization of advanced imaging studies, including ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), may aid in the diagnosis of this disease entity. To review the imaging findings of PSF and demonstrate the value of various cross-sectional imaging (US, CT, and MRI) in the diagnosis of PSF. PSF in five children was verified surgically. Preoperative barium esophagography, US, CT, and MRI were performed selectively in these patients. The clinical and imaging findings are reviewed retrospectively. Barium studies demonstrated the sinus tract in all five patients. US, CT, and MRI demonstrated an associated inflammatory process. By utilizing the trumpet maneuver, the presence of sinus tract was evident in two patients during US. The sinus tract is also demonstrated by CT in another patient. Although barium esophagography is advantageous in demonstration of the sinus tract in PSF, US and CT are also capable of showing the sinus tract. The extent of inflammatory process related to PSF is better delineated by US, CT, and MRI. (orig.)

  18. Anomaly poles as common signatures of chiral and conformal anomalies

    International Nuclear Information System (INIS)

    One feature of the chiral anomaly, analyzed in a perturbative framework, is the appearance of massless poles which account for it. They are identified by a spectral analysis of the anomaly graph and are usually interpreted as being of an infrared origin. Recent investigations show that their presence is not just confined in the infrared, but that they appear in the effective action under the most general kinematical conditions, even if they decouple in the infrared. Further studies reveal that they are responsible for the non-unitary behaviour of these theories in the ultraviolet (UV) region. We extend this analysis to the case of the conformal anomaly, showing that the effective action describing the interaction of gauge fields with gravity is characterized by anomaly poles that give the entire anomaly and are decoupled in the infrared (IR), in complete analogy with the chiral case. This complements a related analysis by Giannotti and Mottola on the trace anomaly in gravity, in which an anomaly pole has been identified in the corresponding correlator using dispersion theory in the IR. Our extension is based on an exact computation of the off-shell correlation function involving an energy-momentum tensor and two vector currents (the gauge-gauge-graviton vertex) which is responsible for the appearance of the anomaly.

    A broad spectrum of congenital upper airway anomalies can occur as a result of errors during embryologic development. In this review, we will describe the clinical presentation, diagnosis, and management strategies for a few select, rare congenital malformations of this system. The diagnostic tools used in workup of these disorders range from prenatal tests to radiological imaging, swallowing evaluations, indirect or direct laryngoscopy, and rigid bronchoscopy. While these congenital defects can occur in isolation, they are often associated with disorders of other organ systems or may present as part of a syndrome. Therefore workup and treatment planning for patients with these disorders often involves a team of multiple specialists, including paediatricians, otolaryngologists, pulmonologists, speech pathologists, gastroenterologists, and geneticists.

  1. Understanding diboson anomalies

    Sajjad, Aqil

    2015-01-01

    We conduct a model-independent effective theory analysis of hypercharged fields with various spin structures towards understanding the recently observed diboson signal as well as possible future excesses involving $WZ$ and $WH$ modes. Within the assumption of no additional physics beyond the standard model up to the scale of the possible diboson resonance, we show that a hypercharged scalar and a spin 2 particle do not have tree-level $WZ$ and $WH$ decay channels up to dimension 5 operators, and cannot therefore account for the anomaly, whereas a hypercharged vector is a viable candidate provided we also introduce a $Z'$ in order to satisfy electroweak precision constraints. We calculate bounds on the $Z'$ mass consistent with the Atlas/CMS diboson signals as well as electroweak precision data.

  2. Hybrid treatment of arteriovenous fistula between popliteal vessels

    Directory of Open Access Journals (Sweden)

    Adenauer Marinho de Oliveira Góes Junior

    2014-12-01

    Full Text Available The authors describe treatment of a patient who presented an arteriovenous fistula between the popliteal vessels more than 20 years after a gunshot wound. The patient underwent endovascular treatment using Viabahn (Gore® stent grafts, but, because of the large disparity in popliteal artery diameters proximal and distal of the fistula, the endovascular treatment was unsuccessful. The superficial femoral artery was then banded around the stent graft that was deployed previously. This improvised strategy allowed an open surgical approach to be performed far from the fistula site, reducing the risks of operating in a region with anatomic distortions and significant enlargement of the surrounding venous structures, which would certainly have increased the likelihood of iatrogenic injuries.

    Vascular complications of lumbar disc surgery are rare. Few cases have been reported. Arteriovenous fistulas are the most common. They are due to anatomical relationships between the last lumbar vertebrae, the corresponding discs, and the iliac vessels; degenerative lesions of the intervertebral discs facilitate instrumental vessel perforation, and operative difficulty. Computed tomography is particularly accurate for making the diagnosis. Treatment strategies consist in surgery or endovascular management. Percutaneous endovascular treatment using a stent-graft is a reasonable option for treating arteriovenous fistula. We describe the case of a 50-year-old patient who developed an iliocaval arteriovenous fistula following lumbar disc hernia surgery. The lesion was excluded by a stent-graft. The postoperative period was uneventful. PMID:26920402

  4. MR angiography of hemodialysis access fistula. Evaluation before PTA procedure

    International Nuclear Information System (INIS)

    We evaluated the feasibility of MR angiography for hemodialysis fistula. Eleven patients with suspected stenosis or occlusion of an autogenous hemodialysis fistula in the forearm underwent MRA. MRA was obtained using both the 3D-PC method and 3D gadolinium contrast-enhanced (CE) method with a knee coil. The two methods were compared with DSA in seven patients. CE-MRA clearly demonstrated the entire dialysis fistula. However, signals of the stenotic area are effaced in PC-MRA. The diameter of the vessels evaluated in the CE-MRA was well correlated with angiography. CE-MRA demonstrated smaller collateral vessels more clearly than PC-MRA. CE-MRA provided useful information before the PTA procedure. (author)

    The value of different diagnostic tests in the detection of colovesical fistulas was studied in 28 surgically proven cases seen during the last 10 years at the University of Michigan, Ann Arbor. Etiologies were diverticulitis (19), Crohn disease (three), postradiation therapy (four), previous trauma (one), and bladder carcinoma (one). The fistulas were demonstrated by barium enema in 10 of 20 patients and by cystography in eight of 26. Cystoscopy was diagnostic in 11 of 25 patients and sigmoidoscopy in four of 24. Methylene blue test was positive in five of six patients, and in one patient given a charcoal enema the material appeared in the urine. The Bourne test, consisting of radiography of the centrifuged urine samples obtained immediately after a nondiagnostic barium enema, was positive in nine of 10 patients. In seven of these 10 patients, the Bourne test was the only positive evidence of an otherwise occult colovesical fistula later proven at surgery. PMID:6608228

    Full Text Available Laser ablation of fistula tract is a safe, effective, sphincter-preserving therapy that can be successfully performed by surgeons. Various studies and papers have been published advocating the use of lasers. However clinical experience and technical expertise is necessary for the use of lasers. Here we present a case of a 45 year old male presenting with acute abdomen following laser ablation of fistula in ano. The patients X-Ray abdomen showed free gas under the diaphragm and was explored. The exploration revealed a pyoperitoneum and a sigmoid perforation for which closure of perforation and a diverting colostomy was done. The patient was further operated for fistula excision and Seton suturing and is planned for colostomy closure. [Int J Res Med Sci 2015; 3(6.000: 1551-1553

  7. Doppler ultrasound in the diagnosis and follow-up of the muscle rupture and an arteriovenous fistula of the thigh in 12 year boy

    International Nuclear Information System (INIS)

    Background. With this case report the authors wish to present the accuracy of non-invasive vascular imaging methods, especially Doppler ultrasound, in the evaluation of the muscular trauma and periskeletal soft tissue vascular anomalies. Case report. Twelve year-old boy has been admitted with the right femoral quadriceps muscle traumatic rupture. Postoperative B-mod sonography (US) visualised recidivuous haematoma and Power Doppler depicted hypervascularized area, suspected vascular malformation (angioma). Doppler findings obtained on the right thigh vasculature gave us reasons to think about posttraumatic arteriovenous fistula. Doppler has been repeated in the specialized paediatric institution with the same results. Digital subtraction angiography, 8 months after trauma, did not confirm suspicions reported in US findings. Spiral computed tomographic angiography (CTA) performed 11 months after trauma clearly depicted a lesion which had been repeatedly described in US findings. Fourteen months after trauma the vascular surgeon performed the deep femoral artery muscular branches ligation, but in the official report only arteriovenous fistula was mentioned. After the surgery the patient was clinically better. The aetiology of the right femoral arteriovenous fistula and hypervascularized structure remains unclear. Conclusions. Every inadequately behaving, recidivous posttraumatic haematoma should be evaluated with Doppler ultrasound. CTA can be performed if it is needed to clarify US findings. (author)

  8. Creation of an Arterio-Venous Fistula Between the Brachial Artery and Basilic Vein with a Saphenous Vein Graft Interposition

    Full Text Available Arteriovenous fistulas for hemodialysis are usually open in the upper extremity. For patients with thrombosed arteriovenous fistulas in this area, alternative fistula access routes are needed. AVF creation with a saphenous vein graft is an alternative hemodialysis access method in the patient who has lost the chance of fistula creation with his native vessels.The aim of this case report is to discuss AV fistula management with a saphenous vein graft between the brachial artery and basilic vein in a hemodialysisdependent patient. In this patient previous fistulas were thrombosed and the native vessels in the upper extremity vessels were not suitable for a new AV fistula creation.

  9. Embolization of a High-Output Postnephrectomy Aortocaval Fistula with Gianturco Coils and Cyanoacrylate

    International Nuclear Information System (INIS)

    The authors describe the endovascular treatment of a high-output, large-caliber, postnephrectomy aortocaval fistula using a mixture of cyanoacrylate and lipiodol combined with Gianturco coil embolization. Thirty-nine coils were used to decrease the flow through the fistula so that a fast-polymerizing glue mixture could be injected into the fistula. During rapid polymerization, the N-butyl-2-cyanoacrylate (NBCA) mixture was trapped within the coils, providing an easily controllable glue cast in the fistula, thereby preventing inadvertent embolization into the lungs. This approach can be of considerable benefit for the endovascular treatment of central high-output fistulas

    Full Text Available We report a case of a traumatic cavernous fistula supplied by a persistent primitive trigeminal artery. The process of treatment was unique in this case. Fistula was subcompletely occluded by coiling from primitive trigeminal artery. Residual fistula was helped to form thrombosis by compression of the carotid artery with hand in the procedure. Long-term follow-up was satisfactory. Traumatic cavernous fistula supplied by a persistent primitive trigeminal artery could be treated by embolization and temporal compression of the parent artery might be useful for residual minimal fistula.

    Detecting anomalies in non-stationary signals has valuable applications in many fields including medicine and meteorology. These include uses such as identifying possible heart conditions from an Electrocardiography (ECG) signals or predicting earthquakes via seismographic data. Over the many choices of anomaly detection algorithms, it is important to compare possible methods. In this paper, we examine and compare two approaches to anomaly detection and see how data fusion methods may improve performance. The first approach involves using an artificial neural network (ANN) to detect anomalies in a wavelet de-noised signal. The other method uses a perspective neural network (PNN) to analyze an arbitrary number of "perspectives" or transformations of the observed signal for anomalies. Possible perspectives may include wavelet de-noising, Fourier transform, peak-filtering, etc.. In order to evaluate these techniques via signal fusion metrics, we must apply signal preprocessing techniques such as de-noising methods to the original signal and then use a neural network to find anomalies in the generated signal. From this secondary result it is possible to use data fusion techniques that can be evaluated via existing data fusion metrics for single and multiple perspectives. The result will show which anomaly detection method, according to the metrics, is better suited overall for anomaly detection applications. The method used in this study could be applied to compare other signal processing algorithms.

    The algebraic structure of chiral anomalies is made globally valid on non-trivial bundles by the introduction of a fixed background connection. Some of the techniques used in the study of the anomaly are improved or generalized, including a systematic way of generating towers of ‘descent equations’.

  16. Anomaly mediation deformed by axion

    International Nuclear Information System (INIS)

    We show that in supersymmetric axion models the axion supermultiplet obtains a sizable F-term due to a non-supersymmetric dynamics and it generally gives the gaugino masses comparable to the anomaly mediation contribution. Thus the gaugino mass relation predicted by the anomaly mediation effect can be significantly modified in the presence of axion to solve the strong CP problem

    I develop the simplest geometric-discretized analogue of two dimensional scalar field theory, which qualitatively reproduces the trace anomaly of the continuous theory. The discrete analogue provides an interpretation of the trace anomaly in terms of a non-trivial transformation of electric-magnetic duality-invariant modes of resistor networks that accommodate both electric and magnetic charge currents.

    Full Text Available Seven cases of adult spinal vascular malformations presenting in conjunction with spinal dysraphism have been reported in the literature. Two of these involved male patients with a combined dural arteriovenous fistula (DAVF and lipomyelomeningocele. The authors present the third case of a patient with an extraspinal DAVF and associated lipomyelomeningocele in a lumbosacral location. A 58-year-old woman with rapid decline in bilateral motor function 10 years after a prior L4-5 laminectomy and cord detethering for diagnosed tethered cord underwent magnetic resonance imaging showing evidence of persistent cord tethering and a lipomyelomeningocele. Diagnostic spinal angiogram showed a DAVF with arterial feeders from bilateral sacral and the right internal iliac arteries. The patient underwent Onyx embolization of both feeding right and left lateral sacral arteries. At 6-month follow-up, MRI revealed decreased flow voids and new collateralized supply to the DAVF. The patient underwent successful lipomyelomeningocele exploration, resection, AV fistula ligation, and cord detethering. This report discusses management of this patient as well as the importance of endovascular embolization followed by microsurgery for the treatment of cases with combined vascular and dysraphic anomalies.

    Introduction: Aortoesophageal fistula is an uncommon but mortal cause of massive upper gastrointestinal bleeding. The most common causes are thoracic aortic aneurisym, foreign body reaction, malignancy and postoperative complication. It can be seen in different pattern on upper gastrointestinal endoscopy. There are surgical, endoscopic and interventional radiological treatment options, however, definitive treatment is surgical intervention. Diagnosis and treatment desicion should be made quickly because of rapid and mortal course. Case report: In this article, a case of aortoesophageal fistula was presented that resulted in mortality as a result of massive bleeding. PMID:26980940

    Pneumobilia, or air within the biliary tree, is a poor prognostic indicator in a patient without prior biliary sphincterotomy. Differential diagnosis includes infection with gas-forming organisms, choledochoenteric fistula in the setting of gallstones or penetrating ulcer disease, malignant invasion from a primary liver or biliary tract tumor, or metastatic disease. Treatment depends on etiology and patient factors, but often requires surgical intervention. We report a patient with gastrointestinal bleeding in whom pneumobilia was incidentally noted on abdominal plain film. Computed tomography and endoscopy revealed the biliary-enteric fistula to be caused by metastatic colon adenocarcinoma invading the biliary tree. PMID:26958563

  11. Anomaly Poles as Common Signatures of Chiral and Conformal Anomalies

    CERN Document Server

    Armillis, Roberta; Rose, Luigi Delle

    2009-01-01

    One feature of the chiral anomaly, analyzed in a perturbative framework, is the appearance of massless poles which account for it. They are identified by a spectral analysis of the anomaly graph and are usually interpreted as being of an infrared origin. Recent investigations shown that their presence is not just confined in the infrared, but that they appear in the effective action under the most general kinematical conditions, even if they decouple in the infrared. Further studies reveal that they are responsible for the non-unitary behaviour of these theories in the ultraviolet (UV) region. We extend this analysis to the case of the conformal anomaly, showing that the effective action describing the interaction of gauge fields with gravity is characterized by anomaly poles that give the entire anomaly and are decoupled in the infrared (IR), in complete analogy with the chiral case. This complements a related analysis by Giannotti and Mottola on the trace anomaly in gravity, in which an anomaly pole has bee...

    Full Text Available Context Pancreaticopleural fistula is a rare complication of pancreatitis. Pleural effusion resulting from a pancreaticopleural fistula is extremely rare and accounts for less than 1% of cases. Due to non-specific clinical presentations of a pancreaticopleural fistula, imaging plays an important role. Magnetic resonance cholangiopancreatography (MRCP is very useful in depicting parenchymal and ductal structural changes along with direct visualization of a pancreaticopleural fistula. Case report We present the case of a middle-aged male with moderate right pleural effusion who had a history of pancreatitis. MRCP showed chronic pancreatitis with a pancreaticopleural fistula. A brief review of the role of imaging in a pancreaticopleural fistula is discussed along with the case. Conclusion MRCP is a useful modality for diagnosing a pancreaticopleural fistula.

    Background The abnormalities of coronary arteries, though rare and sometimes benign, may first present clinically as myocardial infarction or sudden death. Multi-detector computed tomography (MDCT) is a non-invasive test that is highly suitable for detecting these anomalies. The study aimed to review the 64-MDCT appearance of the coronary artery anomalies in 66 patients and to discuss the clinical importance of these anomalies.Methods In 6014 consecutive patients examined over 12 months by 64-MDCT for the study of coronary artery disease, 66 were diagnosed for coronary artery anomalies. All patients were symptomatic for one or more of the following diseases: chest pain, dyspnoea, palpitations, arrhythmia and myocardial infarction. Nine patients had undergone a coronary angiography. All the CT images were evaluated by two radiologists and one cardiologist. The right coronary artery (RCA) and the conus branch arising separately, myocardial bridging and duplication of arteries were not analysed in our study.Results The incidence of coronary artery anomalies found in our study group was 1.097%. In the selected patients, seven different types of coronary anomalies were found by 64-MDCT examination. The high takeoff, origin of the coronary artery from the opposite or noncoronary sinus with an anomalous course, and coronary artery fistula were the three common forms of anomalies (n=16, 18 and 16, respectively). Compared with the results of the coronary angiography, the number of the drainage sites of two coronary artery fistula was less in MDCT images (3 small sites in total). In all cases, coronary artery computed tomography angiography (CTA) technique was able to recognize the origin of the coronary artery, its three-dimensional course and its spatial relationship with the adjacent structures. Conventional coronary angiography in two cases, however, was unable to provide sufficient information for correct and complete diagnosis.Conclusions In conclusion, the study

  16. Binning of satellite magnetic anomalies

    Goyal, H. K.; Vonfrese, R. R. B.; Hinze, W. J.

    1985-01-01

    Crustal magnetic anomaly signals over satellite orbits were simulated to investigate numerical averaging as an anomaly estimator. Averaging as an anomaly estimator involves significant problems concerning spatial and amplitude smoothing of the satellite magnetic observations. The results of simulations suggest that the error of numerical averaging constitutes a small and relatively minor component of the total error-budget of higher orbital anomaly estimates, whereas for lower orbital estimates numerical averaging error increases substantially. As an alternative to numerical averaging, least-squares collocation was investigated and observed to produce substantially more accurate anomaly estimates, particularly as the orbital elevation of prediction was decreased towards the crustal sources. In contrast to averaging, collocation is a significantly more resource-intensive procedure to apply because of the practical, but surmountable problems related to establishing and inverting the covariance matrix for accurate anomaly prediction. However, collocation may be much more effectively used to exploit the anomaly details contained in the lower orbital satellite magnetic data for geologic analysis.

  17. BRS cohomology and topological anomalies

    International Nuclear Information System (INIS)

    The occurrence of non-abelian anomalies in gauge theories and gravitation, first discovered via perturbative techniques, is now completely explained from the mathematical point of view by means of the family index theorem of Atiyah and Singer. Here we make contact between this approach and BRS cohomology, by showing that they yield the same non-abelian anomalies, provided a certain restriction to ''local'' functionals is not introduced from the very beginning. In particular, this solves the ''unicity'' problem for this kind of anomalies. Local BRS cohomology is still relevant for the abelian case. (orig.)

  3. Rendu-Osler-Weber syndrome presenting with pulmonary arteriovenous fistula

    International Nuclear Information System (INIS)

    A pulmonary arteriovenous fistula is an abnormal connection between pulmonary arteries and veins. Patients with Rendu-Osler-Weber syndrome may present with this vascular malformation, which is a typical finding of the disease. Approximately 5-15% of Rendu-Osler-Weber syndrome patients have pulmonary arteriovenous malformations (AVM) and there is usually a family history of AVM in these patients. The malformations are usually located in the lower lobes. In this paper, I describe a 49-year-old male patient with dyspnoea, cough, haemoptysis and epistaxis. Physical examination showed nasal telangiectasias, cyanosis of the lips and nails, and a systolic bruit over the left lung. Chest X-ray revealed a 5-cm mass in the left lower lobe and after magnetic resonance examination, together with 3-D magnetic resonance angiography, it was demonstrated to be a pulmonary arteriovenous fistula. The history of a niece with a similar history of suspected pulmonary arteriovenous fistula led me to consider the possibility of Rendu-Osler-Weber syndrome presenting with a pulmonary arteriovenous fistula.

    AIM: To summarize the operative experience of the transanal approach in acquired rectovestibular fistula repair.METHODS: Ninety-six cases of acquired rectovestibular fistula in young females were analyzed retrospectively. The etiology and operative procedure were discussed. Operative essential points were, the patient was laid in prone frog position, with the knees and hips flexed at 90°; the perineum was elevated; and the anal opening was exposed. Four stay sutures were applied to the margin of the fistular orifice in the anal opening at points 3, 6, 9 and 12 o'clock.A circular incision of mucosa surrounding the stay sutures was made. The fistula was dissected from its anal opening to its vestibular opening. The wound of vestibule was sutured,and the rectoanal wound was then sutured transversely.RESULTS: All the 96 patients recovered uneventfully from operation with a successful rate of 93.75%.CONCLUSION: The transanal approach in the treatment of the acquired rectovestibular fistula is a simple and feasible technique.

    Full Text Available Abstract Introduction Bronchoperitoneal fistulas are extremely rare. We present a case where retained surgical drains from a previous surgery resulted in erosion and fistula formation. This condition required an extensive surgical procedure and advanced ventilator techniques. Case presentation A 24-year-old African-American man presented to our Emergency Department with a one-week history of fever, dyspnea, cough, and abdominal pain. A computed tomography scan of his chest and abdomen revealed bilateral lower lobe pneumonia and two retained Jackson-Pratt drains in the right upper quadrant. He was taken to the operating room for drain removal, a right hemicolectomy, debridement of a duodenal injury, a Roux-en-y duodenojejunostomy, and an end ileostomy. He subsequently became increasing hypoxemic in the intensive care unit and a bronchoperitoneal fistula was diagnosed. He required high-frequency oscillatory ventilation followed by lung isolation, and was successfully resuscitated using these techniques. Conclusion To the best of our knowledge, this is the first known case report of a bronchoperitoneal fistula caused by retained surgical drains. This is also the first known report that details successful management of this condition with advanced ventilatory techniques. This case highlights the importance of follow-up for trauma patients since retained surgical drains have the potential to cause life-threatening complications. When faced with this condition, clinicians should be aware of advanced ventilatory methods that can be employed in the intensive care unit. In this case, these techniques proved to be life-saving.

    Gastrointestinal (GI) fistula is a well-recognized complication of acute pancreatitis (AP). However, it has been reported in limited literature. This study aimed to evaluate the incidence and outcome of GI fistulas in AP patients complicated with infected pancreatic or peripancreatic necrosis (IPN).Between 2010 and 2013 AP patients with IPN who diagnosed with GI fistula in our center were analyzed in this retrospective study. And we also conducted a comparison between patients with and without GI fistula regarding the baseline characteristics and outcomes.Over 4 years, a total of 928 AP patients were admitted into our center, of whom 119 patients with IPN were diagnosed with GI fistula and they developed 160 GI fistulas in total. Colonic fistula found in 72 patients was the most common form of GI fistula followed with duodenal fistula. All duodenal fistulas were managed by nonsurgical management. Ileostomy or colostomy was performed for 44 (61.1%) of 72 colonic fistulas. Twenty-one (29.2%) colonic fistulas were successfully treated by percutaneous drainage or continuous negative pressure irrigation. Mortality of patients with GI fistula did not differ significantly from those without GI fistula (28.6% vs 21.9%, P = 0.22). However, a significantly higher mortality (34.7%) was observed in those with colonic fistula.GI fistula is a common finding in patients of AP with IPN. Most of these fistulas can be successfully managed with different procedures depending on their sites of origin. Colonic fistula is related with higher mortality than those without GI fistula.

    This prospective comparative study of obstetric fistulae (OF) was aimed at identifying risk factors. A total of 80 obstetric fistulae treated at the gynaecological unit of the FMCG, and 80 inpatients without fistulae recruited randomly as controls formed the basis of this study. Through interview and case record review, information on age, parity and marital status was collected. Other features were educational status, occupation and booking status of the pregnancy that might have led to this condition. The duration of labour, place of birth and mode of delivery, including its outcome were also collected. The data were analysed using the Epi Info. The majority of the patients were Hausa/Fulani 87.5%, Muslims 91.2%, with large vesicovaginal fistulae (average size 5.0 cm) mainly resulting from obstructed labour (93.7%). Major risk factors included early age at first marriage (average 14 years), short stature (average height 146.2 cm) and illiteracy (96.3%). Also low social class and lack of gainful employment were factors. Failure to book for antenatal care (93.7%), and rural place of residence (95%) were also factors associated with acquiring the fistulae. Living far away (>3 km) from a health facility also contributed or predisposed to the development of an obstetric fistula. Social violence and stigma associated with the fistulae included divorce, being ostracised as a social outcast, and lack of assistance from relations in terms of finding and funding treatment. This study supports improved access to basic essential obstetric care, family planning services, and timely referral when and where necessary. Universal education will provide a long-term solution by improving the standard of living and quality of life. Especially important are media- and community-based programmes on the ills of teenage marriage and child pregnancy using cultural and religiously-based values to give sound advice.

  11. Prevalence of Congenital Coronary Artery Anomalies and Variants in 2697 Consecutive Patients Using 64-Detector Row Coronary CTAngiography

    International Nuclear Information System (INIS)

    Coronary artery anomalies are not common, but could be very serious. This study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (MDCT). The results of cardiac MDCT study in 2697 consecutive patients were analyzed retrospectively. Acquisition was performed by a 64-detector row CT machine. Imaging results were assessed by experienced radiologists. Myocardial bridging was by far the most frequent coronary variant (n = 576, 21.3%). Eighty-three subjects (3.1%) showed other coronary anomalies and variants. Anomalies of origination and course of the left main coronary artery (LMCA) were detected in 1.09% of the subjects. The frequency of these anomalies in the right coronary artery (RCA), left circumflex artery (LCx), left anterior descending artery (LAD), posterior descending artery (PDA) and obtuse marginal (OM) artery were 1.24%, 0.33%, 0.1%, 0.07% and 0.03%, respectively. The single coronary pattern was seen in 0.18% and coronary fistulas in 0.07%. Based on the fact that coronary CT-angiography using MDCT can display different coronary anomalies, this study shows similar results to other reports on the subject. Future advances in the performance of CT machines will further improve the quality of CT-based cardiac imaging

    Objective: To evaluate the CT features of aorto-right atrial fistula after aortic valve replacement (AVR) or ascending aortic replacement. Methods: Eighty-seven patients with aortic-right atrial fistula underwent CT after operation. The CT features were retrospectively analyzed. Fistula was measured according to maximum width of the shunt. Results: Aorto-right atrial fistula was detected in 87 patients after aortic valve replacement or ascending aortic replacement by CT scan. Among them, 25 patients were diagnosed as mild aorto-right atrial fistula, 47 patients as moderate, and 15 patients as severe. Thirty-seven patients underwent follow-up CT.Among them, 10 patients with mild to moderate aorto-right atrial fistula were considered to have complete regression, 8 patients with mild aorto-right atrial fistula considered to have incomplete regression, 14 patients with mild to moderate aorto-right atrial fistula considered to have stable condition, and 5 patients with moderate aorto-right atrial fistula considered to have progression at the 3-month follow-up. Conclusion: CT is a useful tool for defining aorto-right atrial fistula after AVR or ascending aortic replacement and for evaluating it in follow-up. (authors)

    Full Text Available Context Postoperative fistula formation is an important complication following pancreatic resections. Objective A large volume of literature without uniform conclusions is available regarding various controversies about postoperative pancreatic fistulae. The term postoperative pancreatic fistula includes fistula resulting from any surgery involving pancreas, most commonly pancreaticoduodenectomy and distal pancreatectomy. In this review, we have tried to present a comprehensive account of postoperative pancreatic fistula with particular emphasis on important controversies clouding the subject. Methods We performed Medline literature search for relevant articles using the key words pancreas, pancreatic cancer, pancreatectomy, pancreatoduodenectomy, Whipple’s operation, postoperative, complications, fistula, management and treatment in various combinations with the Boolean operators AND, OR and NOT. Conclusions Postoperative pancreatic fistula is a troublesome complication of pancreaticoduodenectomy. Although the risk factors for postoperative pancreatic fistula have been extensively described, none of the methods recommended for preventing postoperative pancreatic fistula have been conclusively proved to be effective. While endoscopic treatment and percutaneous treatment form important aspects of treatment of postoperative pancreatic fistula, surgery may be required for select cases.

    We study parity odd transport at second order in derivative expansion for a non-conformal charged fluid. We see that there are 27 parity odd transport coefficients, of which 12 are non-vanishing in equilibrium. We use the equilibrium partition function method to express 7 of these in terms of the anomaly, shear viscosity, charge diffusivity and thermodynamic functions. The remaining 5 are constrained by 3 relations which also involve the anomaly. We derive Kubo formulae for 2 of the transport...

    It was shown recently that boundary terms of conformal anomalies recover the universal contribution to the entanglement entropy and also play an important role in the boundary monotonicity theorem of odd-dimensional quantum field theories. Motivated by these results, we investigate relationships between boundary anomalies and the stress tensor correlation functions in conformal field theories. In particular, we focus on how the conformal Ward identity and the renormalization group equation ar...

  20. Situs anomalies on prenatal MRI

    International Nuclear Information System (INIS)

    Objective: Situs anomalies refer to an abnormal organ arrangement, which may be associated with severe errors of development. Due regard being given to prenatal magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US), this study sought to demonstrate the in utero visualization of situs anomalies on MRI, compared to US. Materials and methods: This retrospective study included 12 fetuses with situs anomalies depicted on fetal MRI using prenatal US as a comparison modality. With an MRI standard protocol, the whole fetus was assessed for anomalies, with regard to the position and morphology of the following structures: heart; venous drainage and aorta; stomach and intestines; liver and gallbladder; and the presence and number of spleens. Results: Situs inversus totalis was found in 3/12 fetuses; situs inversus with levocardia in 1/12 fetuses; situs inversus abdominis in 2/12 fetuses; situs ambiguous with polysplenia in 3/12 fetuses, and with asplenia in 2/12 fetuses; and isolated dextrocardia in 1/12 fetuses. Congenital heart defects (CHDs), vascular anomalies, and intestinal malrotations were the most frequent associated malformations. In 5/12 cases, the US and MRI diagnoses were concordant. Compared to US, in 7/12 cases, additional MRI findings specified the situs anomaly, but CHDs were only partially visualized in six cases. Conclusions: Our initial MRI results demonstrate the visualization of situs anomalies and associated malformations in utero, which may provide important information for perinatal management. Using a standard protocol, MRI may identify additional findings, compared to US, which confirm and specify the situs anomaly, but, with limited MRI visualization of fetal CHDs.

    Quantum anomalies give rise to new transport phenomena. In particular, a magnetic field can induce an anomalous current via the chiral magnetic effect and a vortex in the relativistic fluid can also induce a current via the chiral vortical effect. The related transport coefficients can be calculated via Kubo formulas. We evaluate the Kubo formula for the anomalous vortical conductivity at weak coupling and show that it receives contributions proportional to the gravitational anomaly coefficie...

    Full Text Available A large database of anomalies, registered by 220 satellites in different orbits over the period 1971-1994 has been compiled. For the first time, data from 49 Russian Kosmos satellites have been included in a statistical analysis. The database also contains a large set of daily and hourly space weather parameters. A series of statistical analyses made it possible to quantify, for different satellite orbits, space weather conditions on the days characterized by anomaly occurrences. In particular, very intense fluxes (>1000 pfu at energy >10 MeV of solar protons are linked to anomalies registered by satellites in high-altitude (>15000 km, near-polar (inclination >55° orbits typical for navigation satellites, such as those used in the GPS network, NAVSTAR, etc. (the rate of anomalies increases by a factor ~20, and to a much smaller extent to anomalies in geostationary orbits, (they increase by a factor ~4. Direct and indirect connections between anomaly occurrence and geomagnetic perturbations are also discussed.

  4. Aeromagnetic anomalies over faulted strata

    Grauch, V.J.S.; Hudson, Mark R.

    2011-01-01

    High-resolution aeromagnetic surveys are now an industry standard and they commonly detect anomalies that are attributed to faults within sedimentary basins. However, detailed studies identifying geologic sources of magnetic anomalies in sedimentary environments are rare in the literature. Opportunities to study these sources have come from well-exposed sedimentary basins of the Rio Grande rift in New Mexico and Colorado. High-resolution aeromagnetic data from these areas reveal numerous, curvilinear, low-amplitude (2–15 nT at 100-m terrain clearance) anomalies that consistently correspond to intrasedimentary normal faults (Figure 1). Detailed geophysical and rock-property studies provide evidence for the magnetic sources at several exposures of these faults in the central Rio Grande rift (summarized in Grauch and Hudson, 2007, and Hudson et al., 2008). A key result is that the aeromagnetic anomalies arise from the juxtaposition of magnetically differing strata at the faults as opposed to chemical processes acting at the fault zone. The studies also provide (1) guidelines for understanding and estimating the geophysical parameters controlling aeromagnetic anomalies at faulted strata (Grauch and Hudson), and (2) observations on key geologic factors that are favorable for developing similar sedimentary sources of aeromagnetic anomalies elsewhere (Hudson et al.).

    A case of traumatic right coronary artery-right ventricular fistula secondary to a gunshot wound is presented. In addition, the bullet was retained within the interventricular septum. The diagnostic approach, surgical findings and operative procedure of this and other reported cases are discussed. Several key points are emphasized. First, extended follow-up is necessary after trauma to the heart since fistulas may develop years after the initial injury. Second, surgery is generally indicated for fistulas although some data are presented suggesting that small to moderate fistulas may be treated medically. Third, if surgery is undertaken, very careful operative technique must be utilized to locate and close the fistula. Surgical treatment of choice may be coronary arterial ligation with a distal bypass graft if necessary. Postoperative evaluation is mandatory because fistulas may recur. Indications for removal of a foreign body within the myocardium are also discussed. PMID:920619

    The objective was to study the intraoperative hemodynamic effects of closure of residual arteriovenous fistulae during in situ saphenous vein graft procedures. Data on 60 residual arteriovenous fistulae in nine patients (five men) with a median age of 74 years (range 64-83 years) with critical...... lower limb ischemia were obtained. Direct measurements of proximal and distal blood pressures in the graft were taken and simultaneous determinations of volume blood flow proximally and distally in the graft with ultrasound transit time technique before and after closure of residual fistulae were made....... Closure of a fistula with blood flow around or below 100 mL/min did not increase distal outflow, whereas closure of fistulae with higher blood flow resulted in unpredictable changes in distal outflow. Only fistulae with a blood flow above approximately 100 mL/min may be of hemodynamic significance....

    2013-01-01

    Functional vascular access is a prerequisite for adequate haemodialysis treatment in patients with end-stage renal disease. Autogenous arteriovenous fistulae are considered superior to synthetic grafts and central venous catheters; however, fistulae are not without problems. Fistulae thrombosis has become a clinical challenge in nephrology practice, with relevant clinical implications for dialysis patients. Several studies have reported on the feasibility and relatively high-clinical success rate of the endovascular approach to thrombosed fistulae in recent years. However, as repeated interventions are usually required to achieve long-term access survival, maintenance of a previously thrombosed fistulae could be a highly expensive policy. The goals of this article are to provide the reader an insight into the multiple endovascular approaches for thrombosed arteriovenous fistulae, bearing in mind its clinical effectiveness and financial implications.

    Full Text Available Background and objective Treating airway fistulas, including esophagorespiratory fistulas (ERFs, bronchopleural fistulas (BPFs, and tracheomediastinal fistulas (TMFs, is difficult. The aim of this study is to evaluate the safety and clinical efficacy of metallic covered Z-type stents (CZTS for the treatment of airway fistulas through bronchoscopy or fluroscopy. Methods Thirty-eight patients with fistulas between the esophagus, mediastina, and airways (32 ERFs, 5 BPFs, and 1 TMF were retrospectively reviewed after treatment with covered metallic esophageal and airway stents. The fistulas were caused by esophageal (n=26, bronchogenic (n=11, and thyroid (n=1 carcinomas. Results Forty-six fistulas were found in 38 patients. The fistula size ranged from 0.5 cm to 7.0 cm. Forty airway covered metal stents (24 Y-type, 8 L-type, and 8 I-type and 24 esophageal metal stents were placed. Complete responses to the sealing effects of fistulas were noted in 4.3% of all the fistulas, 60.9% showed complete clinical responses, 23.9% showed partial responses, and 10.9% showed no response. An effectivity rate of 89.1% was observed, and the median survival duration of all patients was 5 months. Conclusion The use of CZTS appears to be safe and feasible for the palliative treatment of ERFs, BPFs, and TMFs. Airway stent placement is recommended for patients with ERF. In the event that airway stents fail, esophageal stents should be given. Airway bifurcation stents were observed to be especially suitable for the sealing of fistulas near the trachea carina.

    International Nuclear Information System (INIS)

    We report a case of an iatrogenic arteriovenous fistula complicated by catheter- directed thrombolytic therapy in a patient with acute deep vein thrombosis of a lower extremity. To the best of our knowledge, this is the first report of an arteriovenous fistula between the sural artery and popliteal vein in that situation. As the vessels have a close anatomical relationship, the arteriovenous fistula seems to be a potential complication after endovascular thrombolytic therapy of acute deep vein thrombosis

    The outcome of patients with end-stage renal disease on hemodialysis depends on a functioning vascular access. Although a variety of access options are available, the arteriovenous fistula remains the best vascular access. Unfortunately the success rate of mature fistula use remains poor. The creation of an arteriovenous fistula is followed by altered hemodynamic and biological changes that may result in neointimal hyperplasia and eventual venous stenosis. This review provides an overview of ...

  4. Iatrogenic Arteriovenous Fistula in a Renal Allograft: The Result of a TAD Guidewire Injury

    International Nuclear Information System (INIS)

    A case is presented of an iatrogenic arteriovenous fistula developing in a renal allograft following guidewire manipulation during transplant renal artery angioplasty. Hyperdynamic flow through the fistula was causing a shunt of blood away from the renal cortex as demonstrated on sonography and scintigraphy. Selective embolization was performed, correcting the maldistribution of flow to the peripheral renal cortex. The diagnosis and difficulty in management of asymptomatic renal arteriovenous fistulae is also discussed

  5. The efficacy of CT arteriography for spinal arteriovenous fistula surgery: technical note

    International Nuclear Information System (INIS)

    We performed helical computed tomography with contrast injection into feeding arteries through a selectively introduced microcatheter to provide precise definition of the vascular and bony structure of the spine in patients with spinal arteriovenous fistula. This selective CT arteriography reliably showed structures including abnormal epi- and intradural feeding arteries, the fistula, perimedullary draining veins and surrounding vertebrae preoperatively with a minimal contrast medium load. This technique can facilitate safe, minimally invasive surgical obliteration of the fistula and a favorable outcome. (orig.)

    Two patients, who were on hemodialysis over a femoral arteriovenous fistula, were transplanted in our center. Despite adequate blood pressure, perfusion of the renal allograft remained poor after completion of the vascular anastomoses. Ligation of the femoral arteriovenous fistula (1.6 L/min) led to adequate perfusion. Initial graft function was good. Although it remains unclear whether ischemia of a renal allograft is caused by venous hypertension or vascular steal due to a femoral arteriovenous fistula, it might be necessary to ligate a femoral arteriovenous fistula to obtain adequate graft perfusion.
