  11. Pulmonary embolism after cardiac catheterization

    International Nuclear Information System (INIS)

    We performed lung perfusion scintigrams before and after catheterization in consecutive 15 patients. Both right and left heart catheterization (9 patients), only right heart catheterization (5 patients), and only left heart catheterization (1 patient) were performed using percutaneous femoral approach with catheter introducer. After removal of all catheters, manual compression was carried out, and after completion of the hemostasis, 2 kg sand-bag was placed on the groin for 6 hours and each patient was then confined to complete bed rest for about 24 hours. Of 15 patients, 6 patients (40 %) demonstrated new pulmonary perfusion defects on the next day following catheterization, but these defects disappeared within a week. None of 6 patients with pulmonary embolism were symptomatic, and there were no changes in Chest X-ray films, spirogram and blood chemistry. Frontal plane QRS axis showed the right axis deviation in more than 30 degrees in 2 cases. And PaO2 showed significant decline by more than 10 mmHg in 3 cases. Duration of manual compression was significantly longer (p < 0.01) in patients who developed new perfusion defects than in patients who had no defects. New perfusion defects could develop without right heart catheterization in 1 case. These data suggested that the prolongation of compressing time of the puncture site and/or subsequent hematoma caused by technical failure may be an important factor in the development of pulmonary embolism.

  12. Bleeding complications of femoral catheterization

    International Nuclear Information System (INIS)

    CT has been used to evaluate hematomas resulting from femoral catheterization (percutaneous transluminal coronary angioplasty, cardiac catheterization, angioplasty, valvuloplasty, and venous access) in 21 patients. Four distinct types of hematoma have been identified: retroperitoneal (N = 12); intraperitoneal (N = 3); groin/thigh (N = 9); and abdominal wall (N = 5). Seven patients had hematomas in two locations. CT contributed by estimating transfusion requirement, indicating the need for more intensive monitoring, and predicting the potential need for surgery. Type 1 and 2 bleeds were the most serious and had the most sequelae. Sequelae included transfusion in 17 patients (mean, 5 units/patient) and surgery in two patients

  13. MR-guided cardiac catheterization

    International Nuclear Information System (INIS)

    Exposing young children to X-rays is a source of concern, since the effect is cumulative and it is important to avoid adding to their lifetime dose. This becomes particularly significant in the case of congenital heart disease, as the patients often need life-long monitoring and successive interventions. Alternative imaging techniques are needed in order to eliminate or limit X-ray exposure. This article demonstrates the feasibility of MR-guided cardiac catheterization using passive device visualization. The procedures are performed in a Philips XMR suite, where all or a substantial part of the catheterization procedure is performed with MR guidance, resulting in significant dose savings. (orig.)

  14. Cardiac catheterization and angiography. Third edition

    International Nuclear Information System (INIS)

    This book discusses the papers on cardiac catheterization and angiography. The topics covered are: historical perspective and present practice of cardiac catheterization; angiography principles and utilization of radiologic and cineangiographic equipment; complications, incidence and prevention of side effects of cardiac catheterization; techniques; blood flow measurement of heart; pressure measurement; diagnostic techniques of angiography; special catheter techniques; coronary angiography, temporary and permanent pacemakers, potential role of lasers in the cardiac catheterization and evaluation of cardiac function

  15. Percutaneous approach and transseptal catheterization

    International Nuclear Information System (INIS)

    In contrast, with the direct brachial technique, the percutaneous approach to left and right heart catheterizaiton involves achieving vascular access via needle puncture, obviating surgical isolation of the vessel during either the introduction or subsequent withdrawal of the cardiac catheter. With appropriate skill and knowledge of regional anatomy, the percutaneous technique can be adapted to catheter insertion from a variety of entry sites. Venous catheterization can be performed via the femoral, internal jugular, subclavian, or median antecubital vein, whereas arterial catheterization can be performed via the femoral, brachial, or axillary artery. At the termination of the procedure, the catheters and introducing sheaths are withdrawn, and bleeding from the puncture sites is controlled by the application of direct pressure

  16. Venous thrombosis after cardiac catheterization in infants

    International Nuclear Information System (INIS)

    Factors influencing the rate of post-catheterization venous thrombosis were studied in 180 infants below one year of age. The initial cardiac catheterization was performed either with cutdown technique or percutaneously. At repeat catheterization on the ipsilateral side presence or absence of thrombosis was noted. The overall thrombosis frequency was higher than previously reported, 15.6%. The rate increased with decreasing weight. An increased rate of thrombosis was also found with indwelling femoral vein catheter left in place for more than 24 hours, and infection. In 6 cases, thrombosis involved only the catheterized side and would have been missed by recatheterization from the contralateral side. It was noteworthy that 9 of the thromboses spared the catheterized vessel and engaged only the vena cava. Among factors not influencing thrombosis rate were age, type of cardiac malformation, cyanosis, early operation, catheterization time or balloon septostomy. Percutaneous or cutdown technique did not influence thrombosis rate. (orig.)

    Although the utility of diagnostic cardiac catheterization in the clinical setting has diminished over the last years, due to the emergence of noninvasive imaging modalities, such as echocardiography, magnetic resonance imaging and computed tomography, catheterization for diagnostic reasons still constitutes a valuable tool in certain parts in the workup of pediatric heart disease. As a result, awareness of the main aspects of diagnostic catheterization is of great importance for the clinical cardiologist. In this article, the main variables measured and the main actions performed during diagnostic cardiac catheterization in children are discussed. PMID:26926292

    Full Text Available Ultrasound (US examination of the bladder can precisely determine the bladder volume and is a useful tool in estimating the residual urine volume. Its application is consequently recommended as an alternative to catheterization for the determination of residual urine. Moreover it represents a simple, noninvasive method to predict the outcome of a voiding trial following acute urine retention based on intravesical prostatic protrusion and on the US pattern of the bladder content. In this article, the Authors review the implementation and results of a bladder US program developed for non-medical caregivers at one Emergency Department.

    By ultrasound scanning it was determined that respiratory movements made by chest of healthy and sick person are accompanied by respiratory chest rise of internal jugular veins. During the exhalation of an individual diameter of his veins increases and during the breath it decreases down to the complete disappearing if their lumen. Change of the diameter of internal jugular veins in different phases can influence significantly the results of vein puncture and cauterization in patients. The purpose of this research is development of the method increasing the efficiency and safety of cannulation of internal jugular veins by the ultrasound visualization. We suggested the method of catheterization of internal jugular veins by the ultrasound navigation during the execution of which the puncture of venous wall by puncture needle and the following conduction of J-guide is carried out at the moment of patient’s exhalation. This method decreases the risk of complications development during catheterization of internal jugular vein due to exclusion of perforating wound of vein and subjacent tissues and anatomical structures.

    Khatami, Mohammad Reza; Abbasi, Rozita; Sadigh, Gelareh

    2010-10-01

    Central vein catheterization is a routine and relatively safe procedure in critically ill patients. Complications with this procedure depend to the site of catheterization and the skill of the operator. In addition to the common complications with femoral vein catheterization there are some rare usually preventable side effects related to guide wire and catheter. In our patient who underwent femoral catheterization for acute hemodialysis, we report migration of guide wire through the systemic circulation from the femoral vein to the jugular vein. This is a very rare complication that is a human error and is totally preventable by doing the procedure by a skilled doctor and considering the standards described for central vein catheter insertion. PMID:20852377

  2. Malposition and complications following venous catheterization

    International Nuclear Information System (INIS)

    Malposition and complications following central venous catheterization largely depend on the site of venous approach. Malpositions are very common after subclavian vein catheterization, and even more common after left jugular vein catheterization. On the contrary, their incidence after right jugular puncture is very low. Among complications, pneumothorax is quate common after subclavian vein catheterization, and migration of the catheter towards the heart after right jugular puncture. Vascular damages may occur in any approach: their early detection on chest radiographs very much depends on a rigorous technique. Radiology plays an important role in the early detection of malposition and complications, which is greatly facilitated by a few ml of contrast medium injected through the catheter

  5. Transcutaneous transsplenic catheterization of the splenic vein

    International Nuclear Information System (INIS)

    The authors have developed a method for transcutaneous transsplenic catheterizaton of the portal vein basin and used this method in clinical studies. This method permits a higher quality of spot splenoportography, selective catheterization and embolization of the gastric veins in bleedings from varicose veins of the esophagus in the patients in whom catheterization of the portal vien basin via the transcutaneous transhepatic approach is impossible because of liver tumors of occulusive stenotic deformation of the portal vein

  6. Fluoroscopically guided ureteral catheterization : preliminary experience

    International Nuclear Information System (INIS)

    To evaluate the efficacy of fluoroscopically guided ureteral catheterization without cystoscopic assistance. We evaluated seven patients(male:female=2:5) who were candidates for percutaneous nephrostomy and noted the presence of ureteral strictures caused by metastasis from malignant tumors(n=5), tuberculosis(n=1) and previous ureterolithotomy(n=1). In six patients, retrograde catheterization of the ureter under cystoscopic guidance was failed. Ureter selection was performed with a guide wire and ureteral stent after bladder distension using contrast media which visualized the interureteric ridge. Retrograde catheterization of the ureter was successful in five patients and failed in two. Ureteral stent insertion was performed in three of the five patients, and removal of migrated ureteral stent and insertion of new ureteral stent was performed in two. The mean total procedure time was 35 minutes. Ureteral catheterization failed in two male patients, who underwent percutaneous nephrostomy. An old blood clot was seen in one patient during the procedure, but no complications ensued. Fluoroscopically guided ureteral catheterization without cystoscopic assistance is thought to be a useful procedure for the insertion of a ureteral stent in female patients

  7. Ultrasound-guided subclavian vein catheterization

    International Nuclear Information System (INIS)

    To assess the usefulness of the ultrasound-guided subclavian vein catheterization in difficult patients. We tried subclavian vein catheterization in 18 patients in which conventional blind technique failed(N=9): or was complicated by hemothorax or pneumothorax(N=3): or was prohibited by respirator care(N=4) and severe thoracic deformity(N=2). Initially, the patency of subclavian vein was evaluated with ultrasonography, and then, the puncture of the subclavian vein was performed under the guidance of ultrasonography. Under the fluoroscopy, the patency of the proximal subclavian vein and the superior vena cava was evaluated after contrast-media injection and a catheter was inserted into the subclavian vein and accurately positioned at the superior vena cava. Successful catheterization was performed in 17 patients. In the remaining one patient, we did not perform catheterization because of bilateral subclavian vein thrombosis detected during the procedure. There were no procedure-related complications. Ultrasound-guided subclavian vein catheterization is an easy and safe method even in difficult cases

  8. Cardiac catheterization in infants and children

    International Nuclear Information System (INIS)

    Cardiac catheterization in infants and children allows a unique opportunity to study physiologic effects of simple and complex lesions in a population with almost invariably normal coronary arteries. While morbidity from catherization is low and mortality is almost negligible in older infants and children, the risks are higher among infants under the age of 4 months, many of whom are seriously ill at the time of the study. In recent years there has been an increase in therapeutic procedures undertaken in the catheterization laboratory such as dilatation of stenotic valves and vessels. There has also been an increase in the use of such diagnostic techniques as electrophysiological studies and endomyocardial biopsies. Catheterization and these newer techniques, particularly in the young infant, should be undertaken only by physicians and technicians experienced in this field, using the best equipment available

  9. Iatrogenic intravascular pneumocephalus secondary to intravenous catheterization

    International Nuclear Information System (INIS)

    The presence of pneumocephalus without a history of intracranial or intrathecal procedures is a significant radiographic finding. Although pneumocephalus means a violation of the dural barrier or the presence of infection, intravascular pneumocephalus is different from intraparenchymal pneumocephalus and its benign nature must be known in the presence of intravenous catheterization. Herein, we present a case of iatrogenic intravascular pneumocephalus with CT findings. To our knowledge, there are only a few reported cases of iatrogenic intravascular pneumocephalus in the literature. Careful intravenous catheterization and diagnosis of the condition on imaging helps to prevent unnecessary treatment procedures. (orig.)

  15. Radiation exposure during cardiac catheterization procedures

    International Nuclear Information System (INIS)

    For some time there has been an increased interest in more information about radiation exposure during cardiac catheterization because of: relatively high doses to workers and patient; rapid increase of numbers of examinations; introduction of new procedure-types (e.g. Percutaneous Transluminal Coronary Angiography, PTCA) and introduction of new techniques (e.g. Digital Subtraction Angiography, DSA). This paper reports about a study on the exposure to medical personnel and patient in two major hospitals in the Netherlands. The Total number of cardiac catheterization procedures in both hospitals amounts to circa 3000 per year (approximately 10% of all cardiac procedures c.q. 20% of all PTCA procedures in the Netherlands). This study is related to 1300 cardiac examinations

    Full Text Available Cardiac catheterization for diagnostic and therapeutic purposes has been routinely used since last one year in College of Medical Sciences and Teaching Hospital, Bharatpur, Nepal. Because all cardiac catheterizations involve the insertion of cardiac catheters into the circulatory system, it should not be surprising that a variety of complications can ensue. These complications range from minor problems with no long-term sequelae to major problem even death. A total of 357 consecutive diagnostic and therapeutic cardiac catheterization performed in College of Medical Sciences and Teaching Hospital, Bharatpur between April 2011 to April 2012 were evaluated for their complications. Among them 220 (61.6% were coronary angiogram, 65 (18.2 % percutaneous transluminal coronary angioplasty (PTCA and stenting, 7 ( 1.9 % permanent pacemaker insertion, 65 (18.2% were others including temporary pacemaker insertion, peripheral angiography and carotid angiography. There were 3 deaths (0.84%. Two deaths occurred following coronary angiogram and 1 death following PTCA stenting. Vascular complications occurred in 5 (1.4% patients with groin haematoma in all.

    Cat, Bahar Gulcay; Guler, Sertac; Soyuduru, Murat; Guven, Ibrahim; Ramadan, Hayri

    2015-01-01

    Central venous catheters (CVCs) are often used for various purposes in the emergency departments (ED). The main uses of CVCs in the EDs are emergent hemodialysis, in situations where peripheral vein catheterization cannot be achieved, and continuous invasive hemodynamic monitoring. The complications related to CVC insertion are usually mechanical and observed in the near term after the procedure. Retained CVC guidewire after catheterization is a rare complication in the published reports and usually related with intra- or postoperative settings and jugular or subclavian vein. The present study reported a young female patient who underwent left femoral vein catheterization 6 months earlier in an intensive care unit of another hospital and was diagnosed with complete guidewire retention in the ED. To the best of the authors' knowledge, this is the first case in published reports with a diagnosis of retained CVC guidewire with retrograde migration into the femoral vein. Surprisingly, the patient developed no thrombotic or embolic complication during this 6-month period. PMID:26657235

In situations making urethral catheterization difficult, a guide wire is placed under direct vision. The modified Foley catheter is slid successfully over the guide wire from its distal end throughout the urethral passage into the bladder. Results: The modified Foley catheter was used successfully in our clinic in cases requiring difficult urethral catheterization. Conclusions: This easy and rapid modification of a Foley catheter may minimize the potential complications of blind catheter placement in standard catheterization.

  6. Polypoid cystitis in an adult without history of catheterization

    International Nuclear Information System (INIS)

    Polypoid cystitis is a benign exophytic mucosal lesion of the bladder. Differentiating it from papillary transitional cell carcinoma is difficult due to their similar characteristics. Although indwelling catheter is the main well-known cause of polypoid cystitis, some case reports unrelated to catheterization have been described. However, the radiological findings of polypoid cystitis have rarely been reported. We hereby describe polypoid cystitis in a 20-year-old man without a history of catheterization along with the computed tomographic findings.

    2008-08-01

    Full Text Available PURPOSE: To review and compare the different methods for difficult male urethral catheterization described in selected literature. MATERIALS AND METHODS: A PubMed search was done with the terms "difficult", "failed", or "complications" and "urethral catheterization", "transurethral catheterization", "Foley catheter", "urethral catheter" or "filiforms and followers". All articles addressing the issue of difficult adult male urethral catheterization were included. RESULTS: Six main approaches were identified on the 14 articles included for review: 1 Passage of either a Glidewire, guide wire or filiform under direct vision; 2 Blind passage of a filiform, guide wire, Glidewire or hydrophilic catheter; 3 "The Peel-away® sheath placed on a cystoscope/resectoscope technique"; 4 "The rigid ureteroscope placed inside the 22F Foley technique"; 5 Suprapubic catheterization; and 6 "The instillation of 60 cc of saline through the catheter as it is advanced technique". CONCLUSION: There is a paucity of prospective data comparing the benefits, risks, success rates and complications of the different approaches for difficult Foley catheter placement. Our suggested approach starts with the initial attempt at urethral catheterization with an 18F coude and a 12F silicone catheter. If these fail, using a flexible cystoscope or the blind Glidewire technique are reasonable alternatives. If dilatation of a stricture is necessary, ureteric dilatators or a urethral balloon dilatator are recommended.

  8. Economic evaluation of increasing population rates of cardiac catheterization

    Full Text Available Abstract Background Increasing population rates of cardiac catheterization can lead to the detection of more people with high risk coronary disease and opportunity for subsequent revascularization. However, such a strategy should only be undertaken if it is cost-effective. Methods Based on data from a cohort of patients undergoing cardiac catheterization, and efficacy data from clinical trials, we used a Markov model that considered 1 the yield of high-risk cases as the catheterization rate increases, 2 the long-term survival, quality of life and costs for patients with high risk disease, and 3 the impact of revascularization on survival, quality of life and costs. The cost per quality-adjusted life year was calculated overall, and by indication, age, and sex subgroups. Results Increasing the catheterization rate was associated with a cost per QALY of CAN$26,470. The cost per QALY was most attractive in females with Acute Coronary Syndromes (ACS ($20,320 per QALY gained, and for ACS patients over 75 years of age ($16,538 per QALY gained. However, there is significant model uncertainty associated with the efficacy of revascularization. Conclusion A strategy of increasing cardiac catheterization rates among eligible patients is associated with a cost per QALY similar to that of other funded interventions. However, there is significant model uncertainty. A decision to increase population rates of catheterization requires consideration of the accompanying opportunity costs, and careful thought towards the most appropriate strategy.

  9. Radiation exposure to the child during cardiac catheterization

    International Nuclear Information System (INIS)

    Few data are available regarding radiation exposure to children during cardiac catheterization. Using lithium fluoride thermoluminescent dosimeters, radiation exposure was measured during precatheterization chest roentgenography, fluoroscopy (hemodynamic assessment phase of catheterization) and cineangiography in 30 infants and children, ages 3 days to 21 years. Dosimeters were placed over the eyes, thyroid, anterior chest, posterior chest, anterior abdomen, posterior abdomen and gonads. Average absorbed chest doses were 24.5 mR during chest roentgenography, 5810 mR during catheterization fluoroscopy and 1592 mR during cineangiography. During the complete catheterization, average doses were 26 mR to the eyes, 431 mR to the thyroid area, 150 mR to the abdomen and 11 mR to the gonads. Radiation exposure during pediatric cardiac catheterization is low to the eyes and gonads but high to the chest and thyroid area. To decrease radiation dosage we suggest (1) low pulse-rate fluoroscopy; (2) substitution of contrast echocardiography for cineangiography; (3) large-plate abdominal/gonadal shielding; (4) a selective shield for thyroid area; (5) a very small field during catheter manipulation. Minimum radiation consistent with accurate diagnosis is optimal; however, erroneous or incomplete diagnosis is more dangerous than radiation-related hazards

    Full Text Available Central venous catheterization is an invasive procedure commonly preferred for hemodynamic monitorization, total parenteral nutrition, cardiac pacemaker implantation, long-term use of vasoactive or irritating agents and hemodialysis. We present a 19-year-old woman with acute renal failure scheduled for hemodialysis catheterization. A catheter guidewire extending from the right internal jugular vein to the right external iliac vein was detected in the chest X-ray, taken two hours following catheterization after occurrence of arrhythmia and hypotension. Catheteter guidewire was extracted noninvasively without any complications. Most common reasons for this complication are stated to be attention deficits, lack of experience, overtired staff, and inadequate supervision of trainees. In this paper, we discussed this complication’s causes and preventive methods. (Journal of the Turkish Society Intensive Care 2011; 9:64-7

  13. Bilateral catheterization of inferior petrosal sinous: Utility in Cushing syndrome

    International Nuclear Information System (INIS)

    The aim of this study is to present our experience on bilateral and simultaneous inferior petrous sinus catheterization, on those patients with ACTH -dependent Cushing's syndrome. We describe the procedure and our results. Material and Method: A retrospective study was held between January 2003 and September 2009, including nine patients (2 men, 7 women) presenting ACTH - dependent Cushing's syndrome. Simultaneous inferior petrosal sinus catheterization was performed in all of them, sampling basal ACTH and after CRH stimulation. ACTH levels gradient in different pituitary locations and peripheral blood levels was recorded. Diagnosis was suggested when inappropriate and maintained hypercortisolemia. High urinary free cortisol levels and no response to dexamethasone suppression were detected. Eight out of nine patients had a prior negative imaging test result. Results: Inferior petrosal sinus bilateral catheterization was successfully performed in all cases, with no evidence of further complications. The results showed definitive diagnosis in all cases. In four patients ACTH levels gradient was lateralized to the left, leading to a specific surgical approach. One patient presented pituitary ACTH - secreting adenoma. Two other patients showed ectopic ACTH production, one showed suprarenal adenoma secreting ACTH and other one showed response to pituitary stimulation without side lateralisation, presenting a histological diagnosis of pituitary hyperplasia. Conclusion: Petrosal sinus catheterization is shown to be an efficient procedure to manage Cushing's syndrome differential diagnosis and to obtain specific anatomical information.

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Inadvertent venous catheterizations occur in approximately 9% of lumbar epidural anesthetic procedures with catheter placement and, if not promptly recognized, can result in fatal consequences. The objective of this report is to describe a case of accidental catheterization of epidural venous plexus and its recording by computed tomography with contrast injection through the catheter. CASE REPORT: A female patient in her sixties, physical status II (ASA, underwent conventional cholecystectomy under balanced general anesthesia and an epidural with catheter for postoperative analgesia. During surgery, there was clinical suspicion of accidental catheterization of epidural venous plexus because of blood backflow through the catheter, confirmed by the administration of a test dose through the catheter. After the surgery, a CT scan was obtained after contrast injection through the catheter. Contrast was observed all the way from the skin to the azygos vein, passing through anterior and posterior epidural venous plexuses and intervertebral vein. CONCLUSION: It is possible to identify the actual placement of the epidural catheter, as well as to register an accidental catheterization of the epidural venous plexus, using computed tomography with contrast injection through the epidural catheter.

  16. Managing Inadvertent Arterial Catheterization During Central Venous Access Procedures

    International Nuclear Information System (INIS)

    Purpose: Approximately 200,000 central venous catheterizations are carried out annually in the National Health Service in the United Kingdom. Inadvertent arterial puncture occurs in up to 3.7%. Significant morbidity and death has been reported. We report on our experience in the endovascular treatment of this iatrogenic complication. Methods: Retrospective analysis was carried out of 9 cases referred for endovascular treatment of inadvertent arterial puncture during central venous catheterization over a 5 year period. Results: It was not possible to obtain accurate figures on the numbers of central venous catheterizations carried out during the time period. Five patients were referred with carotid or subclavian pseudoaneurysms and hemothorax following inadvertent arterial catheter insertion and subsequent removal. These patients all underwent percutaneous balloon tamponade and/or stent-graft insertion. More recently 4 patients were referred with the catheter still in situ and were successfully treated with a percutaneous closure device. Conclusion: If inadvertent arterial catheterization during central venous access procedures is recognized and catheters removed, sequelae can be treated percutaneously. However, once the complication is recognized it is better to leave the catheter in situ and seal the artery percutaneously with a closure device

    Full Text Available Urethral stone is a rare entity in clinical practice. Primary urethral stone happening directly in urethra is even rare, and it usually occurs as a result frequent urinary infection, urethral stricture and trauma.While the application of clear intermittant catheterization reliably protects bladder function, in long term use, it may cause various complications.In this case, we discussed giant urethral stone in a patient who has been acting clean intermittent catheterization regularly and without problem fort he last five years and who has had total loss of sensation in this lower extremity as a result of falling from height. Considering that the urethral calibration, in the patient acting clean intermittent catheterization is interesting, the giant urethra stone as much as examined such a case has not been presented in literature.In the patient acting clean intermittent catheterization and having loss of urethral sensation and with neurogenic bladder, we call attention to urethral pathologies the symptoms of which were seeing late

    Full Text Available Jai H Seth, Collette Haslam, Jalesh N Panicker Department of Uro-Neurology, University College London Institute of Neurology and the National Hospital for Neurology and Neurosurgery, London, UK Abstract: Patient performance of clean intermittent self-catheterization is a crucial component of the management of incomplete bladder emptying, which can arise from a variety of conditions. This allows patients to have more control over their bladder emptying, and avoids the inconveniences that come with an indwelling urethral catheter. There are, however, barriers that patients face when performing this task which may ultimately limit adherence. In this article, these barriers are discussed in more detail with potential solutions to counter them. Keywords: clean intermittent self-catheterization, catheters, barriers, compliance, adherence

    Lobar emphysema is an uncommon cause of respiratory distress in infancy. Congenital heart disease is seen in about 20% of the patients with infantile (congenital) lobar emphysema. We described six infants with lobar emphysema. In three of them a congenital heart disease was demonstrated by cardiac catheterization and cineangiography; two had a tetralogy of Fallot with right aortic arch and the third infant a ventricular septal defect. The pulmonary angiography showed stretching of the arteries with very poor filling of the peripheral arteries and a characteristic smaller pulmonary vein in the affected lobe. In all the six patients the pulmonary artery pressure was normal. All the patients underwent lobectomy with good results. We feel that a preoperative cardiac catheterization and cineangiography is of value in this very sick group of infants.

    Full Text Available Background: The aim of this study was to determine the most appropriate time for urinary catheter removal following a gynecological surgery.Methods: Critical appraisal of clinical trial articles were conducted. It was aimed to answer our clinical question whether 24-hour postoperative urinary catheter removal is superior compared to other durations in avoiding postoperative urinary retention (PUR and urinary tract infection (UTI. The search was conducted on the Cochrane Library® and PubMed® using keywords “postoperative urinary retention”, “postoperative catheterization” and “urinary retention AND catheterization”. Reference lists of relevant articles were searched for other possibly relevant trials.Results: Seven articles were available as full text, then appraisals of six prospective RCTs involving 846 women underwent hysterectomy and vaginal prolapse surgery were performed finding at the re-catheterization and UTI rate. Subjects in earlier-removal groups were 3 to 4 times more likely to have re-catheterization (OR = 3.10-4.0 compared to later-removal groups, while they who have it removed on 5th day were 14 times more likely to develop UTI compared with immediate group (OR = 14.786, 95% CI 3.187- 68.595.Conclusion: The 24-hour catheterization policy in hysterectomy and vaginal prolapse surgery remains most appropriate although associated with an increased risk of re-catheterization. The removal of catheter before 24 hour (6 or 12 hour could be considered to be used as one of interventions in further RCT(s to find out the best duration which would result in lowest incidence in both of UTI and  PUR.

    Blalock-Hanlon atrial septectomy (BH) is performed to increase systemic and pulmonary venous mixing at the atrial level. Failure of clinical improvement may be related to inadequate intraatrial communication. A simple catheterization technique employing a balloon catheter is used to assess the presence or absence of the limbus of the foramen ovale following BH, since persistence of the limbus of the fossa ovalis after BH is associated with significantly smaller percentage of communication (atrial communication area/total atrial area).

  8. Complications of cardiac catheterization: Incidence, causes, and prevention

    International Nuclear Information System (INIS)

    The Cooperative Study involved a small group of major medical centers at a time when the caseload involved primarily valvular heart disease; coronary angiography was a part of the catheterization procedure in only 27% of the patients in that report. In contrast, the Registry report from the Society for Cardiac Angiography, based on self-reporting from a mixture of academic and private laboratories, covered a time period when suspected or known coronary artery disease was the commonest indication for catheterization: 41,204 of the 53,581 patients (77%) were studied by coronary angiography and did not have valvular, congenital, or other types of coronary disease. Major complications (including death, myocardial infarction, stroke, serious arrhythmias, vascular injury) occurred in 1.82% of cases in the Registry report, less than the 3.4% serious complication rate in the Cooperative Study. While this difference may represent improvement in the safety of cardiac catheterization in the 14 years separating the two studies, it is worth noting that in the Registry report at least 28% of the patients studied had either minimal or no cardiac disease. Thus, laboratories where the percentage of normal or nearly normal studies is lower may expect to have a higher rate of death and other major complications than 1.8%

  9. Applications and complications of subclavian vein catheterization for hemodialysis

    International Nuclear Information System (INIS)

    Objective: To study the indications, complications and duration of 605 subclavian catheters inserted over a period of 4 years as venous access for the management of renal failure in local setup. Results: Among the patients who underwent subclavian vien catheterization, 75.2% patients were suffering from chronic renal failure and 24.7% patients were admitted for acute renal failure. Among chronic renal failure patients, 21.9% catheters had to be replaced due to various complications e.g. thrombosis, infection or kinking of the catheter. The subclavian catheters remained in place for a mean duration of 4 weeks. Early complications encountered were arterial puncture, inability to cannulate the innominate vein, hemo thorax, punctures of thoracic duct, hemo mediastinum, arrhythmias and pulmonary hematoma in 10.7%, 16.5%, 0.5%, 0.2%, 0.6% and 0.2% of patients respectively. Mortality attributed to the procedure occurred in 0.1 % cases. Delayed complications included early infection in 15% catheterizations while delayed infection occurred in 39 % cases. Conclusion: Percutaneous subclavian catheterization is valuable, relatively easy to learn and safe method with acceptable rate of complications for patients necessitating hemodialysis and no established permanent vascular access.

  10. Accurate measurement of oxygen consumption in children undergoing cardiac catheterization.

    2013-01-01

    Oxygen consumption (VO(2) ) is an important part of hemodynamics using the direct Fick principle in children undergoing cardiac catheterization. Accurate measurement of VO(2) is vital. Obviously, any error in the measurement of VO(2) will translate directly into an equivalent percentage under- or overestimation of blood flows and vascular resistances. It remains common practice to estimate VO(2) values from published predictive equations. Among these, the LaFarge equation is the most commonly used equation and gives the closest estimation with the least bias and limits of agreement. However, considerable errors are introduced by the LaFarge equation, particularly in children younger than 3 years of age. Respiratory mass spectrometry remains the "state-of-the-art" method, allowing highly sensitive, rapid and simultaneous measurement of multiple gas fractions. The AMIS 2000 quadrupole respiratory mass spectrometer system has been adapted to measure VO(2) in children under mechanical ventilation with pediatric ventilators during cardiac catheterization. The small sampling rate, fast response time and long tubes make the equipment a unique and powerful tool for bedside continuous measurement of VO(2) in cardiac catheterization for both clinical and research purposes.

  13. A new puncture needle (Seldinger technique) for easy antegrade catheterization of the superficial femoral artery

    International Nuclear Information System (INIS)

    Mainly for anatomical reasons a guide-wire or a catheter has a tendency to turn into the deep femoral artery during antegrade catheterization of the lower limb. To overcome this problem a curved puncture needle has been designed which allows positioning of the guide-wire in an anterior direction. Antegrade catheterization of the superficial femoral artery was achieved in 25 patients without lengthy manipulations or complications. With this technique the rate of complications at antegrade catheterization will probably be reduced. (orig.)

  16. Radiation induced chromosomal aberrations after cardiac catheterization and angiocardiography

    International Nuclear Information System (INIS)

    The relationship between the radiation doses and the chromosomal aberrations of peripheral lymphocytes was studied in patients under-going catheterization with or without angiocardiography. The radiation doses were estimated and chromosomal aberration analyses were carried out in 17 cases. They consisted of 10 males and 7 females at the age of 4 to 26 years with an average of 14 years. Doses in the chest and gonadal regions were measured with calibrated thermoluminescent dosimeters. Peripheral blood samples were taken immediately before and after the diagnostic procedure for chromosome analyses. Results showed that the average doses in the gonad region during cardiac catheterization with and without angiocardiography were 2.4 and 0.83 kC/kg respectively, while those in the chest region were as high as 0.93 and 0.54 kC/kg respectively. The chromosome aberration rate in both groups were significantly higher (2.75-3.33%) than the control value (0.22-0.75%) which was determined before X ray examination. No statistically significant difference of chromosome aberration yield was found between the two groups with and without angiocardiography

  17. Two cases of chronic radiodermatitis caused by cardiac catheterization

    International Nuclear Information System (INIS)

    Coronary angiography (CAG) and percutaneous transluminal coronary angioplasty (PTCA) associated with fluoroscopy and cineradiography deliver higher radiation doses than any other conventional methods and, as a result, expose patients to ionizing radiation. We herein report two cases of radiodermatitis caused by cardiac catheterization whose irradiation dose could be retrospectively calculated. One sixty-year-old female and one sixty eight-year-old female who had suffered from myocardial infarction and angina pectoris, respectively, developed erythematous plaques on the right submammary area and the lesions were initially diagnosed to be fixed drug eruptions. The lesions of submammary area gradually showed the findings of poikiloderma and finally demonstrated ulceration, however, we could not make an accurate diagnosis at that time, due to our lack of knowledge about these radiologic examinations. The cumulative irradiation dose of these cases was calculated to be 58.5 Gy and 45.5 Gy, respectively, and both cases were finally diagnosed to have chronic radiodermatitis as a result of cardiac catheterization.

  18. A study of exposure dose reduction in cineless cardiac catheterization

    International Nuclear Information System (INIS)

    In cardiac catheterization, in what extent the cineless procedure reduces the radiation exposure dose to patients and room scattering was examined in comparison with the ordinary procedure (cine- and digital-procedure). Apparatuses were Siemens BICOR HS/HICOR, Polydoros and Toshiba Super G/DFP2000A, KXO-80C/D. For measuring the exposure dose to patients, TLD devices (Kasei Optonics Ltd.) were inserted in the regions of lens, thyroid, petrosa, liver, genital organ, chest wall and back of the phantom (Kyoto Kagaku Ltd.), which was exposed according to the cine- or digital-procedure for cardiac catheterization at the routine angulation. For the dose to the operator, the phantom, placed at the operation site, with the devices was exposed similarly. Scattering radiation was measured with an ionizing chamber-survey meter ICS-311 (ALOKA Ltd.) and dosemeter NOMEX (Toyo Medics Ltd.). Cineless procedure was found to reduce the exposure dose to patients to 30-50% and to the operator to 50%, and the scattering radiation dose to 25%. (K.H.)

  19. Radiation Doses in Some Cardiac Catheterization and Angiography Procedures

    International Nuclear Information System (INIS)

    Interventional radiology involves diagnostic and therapeutic procedures that range from simple to complex. Patients can be subjected to varying radiation doses. The study aims to determine the variation in patient entrance doses of pediatric and adult patients who underwent selected cardiac catheterization and angiography procedures at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. It is also aimed to investigate the methods for optimizing radiation protection. A total of 761 pediatric patients and 114 adult patients for cardiac catheterization and 320 adults for angiography were included in the study. Results showed that pulmonary and PDA are high dose procedures yielding to an average effective dose of 10 and 8.2 mSv respectively. DAP values showed a good correlation with effective doses for diagnostic and COA dilatation with r2 equal to 0.81 and 0.70 respectively. PTCA procedure delivered a maximum skin dose that exceeded the threshold dose for skin erythemia with a value of 4.5 Gy. Percutaneous Transhepatic Choleangiography (PTC) and Transjugular Intrahepatic Portosystemic Shunts (TIPSS) delivered the maximum skin dose of 983 and 735 mGy. The study recommends that a review of the protocols and setting of image quality criteria for pediatric especially for age groups 0 and 1 and adult patients should be made in order that fluoroscopy time , peak kilovoltage and number of cine series be reduced.

  20. Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization

    Science.gov (United States)

    Wang, Chu

    Patients undergoing cardiac catheterization are potentially at risk of radiation-induced health effects from the interventional fluoroscopic X-ray imaging used throughout the clinical procedure. The amount of radiation exposure is highly dependent on the complexity of the procedure and the level of optimization in imaging parameters applied by the clinician. For cardiac catheterization, patient radiation dosimetry, for key organs as well as whole-body effective, is challenging due to the lack of fixed imaging protocols, unlike other common X-ray based imaging modalities. Pediatric patients are at a greater risk compared to adults due to their greater cellular radio-sensitivities as well as longer remaining life-expectancy following the radiation exposure. In terms of radiation dosimetry, they are often more challenging due to greater variation in body size, which often triggers a wider range of imaging parameters in modern imaging systems with automatic dose rate modulation. The overall objective of this dissertation was to develop a comprehensive method of radiation dose estimation for pediatric patients undergoing cardiac catheterization. In this dissertation, the research is divided into two main parts: the Physics Component and the Clinical Component. A proof-of-principle study focused on two patient age groups (Newborn and Five-year-old), one popular biplane imaging system, and the clinical practice of two pediatric cardiologists at one large academic medical center. The Physics Component includes experiments relevant to the physical measurement of patient organ dose using high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response variations in three-dimensional angular orientations. The results were to be used as angular dependence

    Background. Multiple sclerosis (MS) healthcare providers (HCP) have undergone considerable educational efforts regarding the importance of evaluating and treating pelvic floor disorders, specifically, urinary dysfunction. However, limited data are available to determine the impact of catheterization on patient quality of life (QoL). Objectives. To describe the use of urinary catheterization among MS patients and determine the differences between those who report positive versus negative impact of this treatment on QoL. Methods. Patients were queried as part of the 2010 North American Research Committee On Multiple Sclerosis survey; topics included 1) urinary/bladder, bowel, or sexual problems; 2) current urine leakage; 3) current catheter use; 4) catheterizing and QoL. Results. Respondents with current urine leakage were 5143 (54.7%), of which 1201 reported current catheter use (12.8%). The types of catheters (intermittent self-catheterization and Foley catheter (indwelling and suprapubic)) did not differ significantly. Of the current catheter users, 304 (25.35%) respondents reported catheterization negatively impacting QoL, 629 (52.4%) reported a positive impact on QoL, and 223 (18.6%) reported neutral QoL. Conclusions. A large proportion of catheterized MS patients report negative or positive changes in QoL associated with urinary catheterization. Urinary catheterization does not appear to have a universally negative impact on patient QoL. PMID:25006498

  2. Catheterization of the Hepatic Artery Via the Left Common Carotid Artery in Rats

    International Nuclear Information System (INIS)

    The commonly used approach for rat hepatic artery catheterization is via the gastroduodenal artery, which is ligated after the procedure. A new method of rat hepatic artery catheterization via the left common carotid artery (LCCA) is described. The LCCA is repaired after catheterization. The catheterization procedures included the following: (1) opening the rat's abdominal cavity and exposing the portion of abdominal aorta at the level of the celiac trunk; (2) separating and exposing the LCCA; inserting a microguidewire and microcatheter set into the LCCA via an incision; after placement into the descending aorta, the microguidewire and microcatheter are maneuvered into the hepatic artery under direct vision; (3) after transcatheter therapy, the catheter is withdrawn and the incision at the LCCA is repaired. This technique was employed on 60 male Sprague-Dawley rats with diethylnitrosamine-induced liver cancer, using a 3F microguidewire and microcatheter set. Selective hepatic artery catheterization was successfully performed in 57 rats. One rat died during the operation and five rats died within 7 days after the procedure. It is envisaged that as experience increases, the catheterization success rate will increase and the death rate will decrease. A new approach for selective hepatic artery catheterization via the LCCA in rats is introduced, which makes repeat catheterization of this artery possible and allows large embolization particles to be delivered by using a 3F catheter

  3. The present and future of interventional catheterization for congenital heart disease

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@Over the past decade, the focus of the pediatric catheterization laboratory has changed dramatically from its primary function of providing diagnosis to offering treatment.Since Rashkind first described the technique for atrial septostomy in the setting of complete transposition of the great arteries in 1966, therapeutic catheterization techniques have replaced conventional surgery, including both corrective and palliative surgeries, for many lesions. Interventional catheterization has become an important modality in the treatment of congenital heart disease. In addition, in the staged management of complex congenital heart disease, better outcomes have been acquired by combined surgical and interventional catheterization strategies. Although great advances have been made in the therapeutic catheterization for congenital heart disease in some Chinese medical centers, there is considerable difference in both clinical applications and basic researches between China and other developed countries. Thus, it is very important to expand this advanced technique aggressively but carefully.

  4. The classification of complex vessels and the catheterization technique in hepatic artery endovascular

    International Nuclear Information System (INIS)

    For interventional therapy of hepatic carcinoma, the anatomical pathway and the variation of complex vessels often cause difficulties in performing super-selective catheterization, or even result in catheterization failure. Understanding of the vascular variations and finding out the effective technique of catheterization can surely reduce the radiation exposure dose to both the operators and patients, and in the same time, can increase the successful rate of super-selective catheterization, which will undoubtedly improve the curative effect. More than 30 thousand times of interventional managements for hepatic carcinoma have been performed in our hospital, from which the author has selected some successful cases as well as some unsuccessful cases to make a technical analysis in order to sum up the experience of super-selective catheterization for clinical physicians' reference.

    Full Text Available This paper presents a cross-functional effort in a US community hospital for an overall process improvement in its Cardiac Catheterization Lab (CCL. One of the key system performance metrics identified was the patient turnaround time. The objective of this study was to identify the sources of delays in the system that lead to prolonged patient turnaround time using a structured lean approach. A set of qualitative recommendations were proposed and implemented. Quantification of some of these recommendations and certain additional ‘what-if’ scenarios were evaluated using Discrete Event Simulation (DES. The simulation results showed that significant reduction in patient turnaround time could be achieved if the proposed recommendations were implemented. This study demonstrated the benefits of adopting the lean philosophy in the continuous process improvement journey in the healthcare delivery arena.

    Near-infrared spectroscopy (NIRS) is a noninvasive method used to evaluate tissue oxygenation. We evaluated the relationship between cerebral and renal NIRS parameters during transcatheter intervention and adverse events in the catheterization room. Between January 1 and May 31, 2012, 123 of 163 pediatric patients undergoing cardiac catheterization were followed by NIRS. All were monitored by electrocardiography, noninvasive blood pressure measurement, pulse oxymetry, initial and final blood lactate level measurement. The number of interventional procedures was 73 (59%). During the procedures, 39 patients experienced a total of 41 adverse events: 18 (19.5%) had desaturation, 10 (8.1%) arrhythmia, three (2.4%) had respiratory difficulty, six (4.8%) had a situation calling for cardiopulmonary resuscitation, three (2.4%) had anemia necessitating transfusion, and one (0.8%) had a cyanotic spell. Cranial NIRS values worsened in 12 (9.8%) and renal measurements worsened in 13 (12.5%) patients. The sensitivity and specificity of a 9% impairment of cranial values were 90 and 61%, respectively, while the corresponding calculations for a 21% fall in renal measurements were 54% sensitivity and 90% specificity. When arrhythmia developed, NIRS values fell simultaneously, while the development of a desaturation problem was heralded by NIRS falling 10-15 s earlier than changes in pulse oxymetry; on improving saturation, NIRS returned to earlier values 10-15 s before pulse oxymetry readings. NIRS monitoring may provide an early warning with regard to complications likely to develop during a procedure. A fall of 9% in cranial NIRS values, or of 21% in renal measurements, should raise clinician awareness. PMID:24404951

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

  18. Percutaneous hepatic arterial catheterization for infusion chemotherapy in treatment of primary hepatoma

    International Nuclear Information System (INIS)

    Chemotherapy offers palliative treatment to patient with advanced nonresectable hepatoma. The usefulness of systemic chemotherapy is limited because of serious side reaction and low concentration of drug at tumor. But this problem may be overcome by intraarterial infusion. Nonsurgical percutaneous hepatic arterial catheterization was done in 21 patients with primary hepatoma, and infusion chemotherapy was done in 19 patients who were successful in catheterization. The results were as follows: 1. Selective catheterization of hepatic artery proper, common hepatic artery, and celiac artery were successful in 4, 9 and 4 patients respectively. The success rate of selective catheterization is 80.9% including celiac artery among 21 patients with hepatoma. 2. Simple catheterization method was applied in 14 patients, and catheter exchange and Loop methods were applied in 2 and 1 patient respectively. 3. Complication related to catheterization, such as infection and bleeding on punctured site, intimal injury and dislodgement of catheter were not serious. 4. Drugs were well tolerated without serious toxicity or complication. 5. 3 patients showed objective response and median survival time of treated patients is 2.5 months.

    The primary objective of this study was to determine the patient and staff dose during cardiac catheterization procedures in Ahmed Gasim Hospital, Khartoum Bahry. A survey of patient and staff exposure was performed covered 2 Cath Lab units from 2 manufacturers. The measurements involved 50 operations. The medical staff was monitored using TLD chips (LiF: Mg, Cu, P). The main operator who was closer to the patient and the x-ray tube, was monitored at six positions (forehead, neck chest - over the lead apron, waist - under the lead apron, leg, and hand), while the exposure to the assistant was measured at two positions (chest - over the lead apron, and hand), where the technologist and the circulator were monitored at one position (chest - over the lead apron). patient exposure was measured using the DAP meter. The main operator and the rest of the staff received 0.14, 0.01 mSv/y respectively. The estimated patient dose rate was found to be 125 mGy/min which considered higher than the recommended DRL for the continuous high mode fluoroscopy used in interventional radiology (100 mGy/min). The study concluded to the fact that the main operator received relatively high dose which is a direct result to the poor radiation protection in the department. (Author)

  20. Optimization of radiation protection in pediatric cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Cardiac catheterization is among the interventional radiology procedures considered to give high doses to adult and pediatric patients. However, almost every year, the number of pediatric patients undergoing these procedures tends to increase. The King Faisal Specialist Hospital and Research Centre (KFSH and RC) is a tertiary level medical center in Riyadh, Kingdom of Saudi Arabia with a 600 bed capacity. Diagnostic X ray procedures (radiography and fluoroscopy) average to about 150,000 annually. Pediatric cardiac catheterization procedures average to about 2,000 cases annually. Due to the limited published data on radiation doses to pediatric patients undergoing these procedures, a study was conducted to assess the doses in pediatric patient undergoing cardiac catheterization procedures and to determine the factors contributing to high doses. Patient and occupational doses during interventional procedures depend on procedure type, fluoroscopy time, number of images, equipment performance and training of the interventionist. KFSH and RC has four X ray rooms in its Cardiac Catheterization Laboratory. There is only one X ray room that is dedicated for pediatric procedure and it was selected for the study. This room is equipped with a Siemens Bicor + biplane X ray unit with HVL of 3.5 mm Al each for the two X ray tubes. The equipment geometry allows the system to have X ray beams in the vertical, horizontal and oblique directions. The system has a built-in DAP meter. Data on quality control tests and DAP calibration performed by the in-house biomedical engineer of Siemens was retrieved. The DAP calibration data supplied by the engineer were verified using a Diamentor M1 (PTW, Freiburg, Germany) DAP meter and following the NRPB protocol. Results of the quality control tests on the X ray machine generator were investigated. The dose area product values from records of pediatric patients in the age groups of 0 (neonates), 1, 5 and 10 years on four common procedures were

    The Multipurpose technique for coronary arteriography employs a single catheter. The benefits are a reduction in the cost of the procedure and a shorter procedural time by experienced operators. To enhance the performance of these catheters, a modification was made in the materials and tip design, and these modifications were clinically evaluated in a small study. Compared to the control group of patients (n = 41), patients catheterized with the Multipurpose-SM (n = 43) were shown to have a shorter procedural time as measured by a reduced fluoroscopy time (7.08 min vs. 9.52 min, P = .007). This difference is statistically significant at a 95% confidence level and resulted in less radiation exposure to the operator and cath lab staff. The procedural time was significantly reduced by fewer catheter exchanges (19% study vs. 46% control; P = .006), which were needed to successfully complete the procedure. The new Multipurpose-SM catheter also demonstrated enhanced flexibility for cannulating coronary arteries with superior or anterior takeoffs. This study concludes that the utilization of a modified Multipurpose-SM catheter is safe and effective in cannulating both the left and right coronary arteries, bypass grafts, and performing left ventriculography. The primary benefits of using this modified catheter are reduced fluoroscopy time and the need for fewer catheter exchanges. PMID:7834732

    Many recent innovations have been made in developing new antiplatelet and anticoagulant drugs in the last few years, with a total of nine new antithrombotic drugs approved by the Food and Drug Administration after the year 2000. This has revolutionized the medical therapy given to manage acute coronary syndrome and support cardiac catheterization. The concept of dual antiplatelet therapy has been emphasized, and clopidogrel has emerged as the most-popular second antiplatelet drug after aspirin. Newer P2Y12 inhibitors like prasugrel and ticagrelor have been extensively studied and compared to clopidogrel. The role of glycoprotein (Gp) IIb/IIIa inhibitors is being redefined. Other alternatives to unfractionated heparin have become available, of which enoxaparin and bivalirudin have been studied the most. Apart from these, many more drugs with novel therapeutic targets are being studied and are currently under development. In this review, current evidence on these drugs is presented and analyzed in a way that would facilitate decision making for the clinician. For this analysis, various high-impact clinical trials, pharmacological studies, meta-analyses, and reviews were accessed through the MEDLINE database. Adopting a unique interdisciplinary approach, an attempt has been made to integrate pharmacological and clinical evidence to better understand and appreciate the pros and cons of each of these classes of drugs.

    OBJECT Urgent ventriculostomy placement can be a lifesaving procedure in the setting of hydrocephalus or elevated intracranial pressure. While external ventricular drain (EVD) insertion is common, there remains a high rate of suboptimal drain placement. Here, the authors seek to demonstrate the feasibility of an ultrasound-based guidance system that can be inserted into an existing EVD catheter to provide a linear ultrasound trace that guides the user toward the ventricle. METHODS The ultrasound stylet was constructed as a thin metal tube, with dimensions equivalent to standard catheter stylets, bearing a single-element, ceramic ultrasound transducer at the tip. Ultrasound backscatter signals from the porcine ventricle were processed by custom electronics to offer real-time information about ventricular location relative to the catheter. Data collected from the prototype device were compared with reference measurements obtained using standard clinical ultrasound imaging. RESULTS A study of porcine ventricular catheterization using the experimental device yielded a high rate of successful catheter placement after a single pass (10 of 12 trials), despite the small size of pig ventricles and the lack of prior instruction on porcine ventricular architecture. A characteristic double-peak signal was identified, which originated from ultrasound reflections off of the near and far ventricular walls. Ventricular dimensions, as obtained from the width between peaks, were in agreement with standard ultrasound reference measurements (p measurement of the stylet distance to the ventricular wall (p < 0.05), which assisted in catheter guidance. CONCLUSIONS The authors have demonstrated the ability of the prototype ultrasound stylet to guide ventricular access in the porcine brain. The alternative design of the device makes it potentially easy to integrate into the standard workflow for bedside EVD placement. The availability of a fast, easy-to-use, inexpensive guidance system can

The concept of dual antiplatelet therapy has been emphasized, and clopidogrel has emerged as the most-popular second antiplatelet drug after aspirin. Newer P2Y12 inhibitors like prasugrel and ticagrelor have been extensively studied and compared to clopidogrel. The role of glycoprotein (Gp IIb/IIIa inhibitors is being redefined. Other alternatives to unfractionated heparin have become available, of which enoxaparin and bivalirudin have been studied the most. Apart from these, many more drugs with novel therapeutic targets are being studied and are currently under development. In this review, current evidence on these drugs is presented and analyzed in a way that would facilitate decision making for the clinician. For this analysis, various high-impact clinical trials, pharmacological studies, meta-analyses, and reviews were accessed through the MEDLINE database. Adopting a unique interdisciplinary approach, an attempt has been made to integrate pharmacological and clinical evidence to better understand and appreciate the pros and cons of each of these classes of drugs.

  6. Routine preoperative cardiac catheterization necessary before repair of secundum and sinus venosus atrial septal defects

    International Nuclear Information System (INIS)

    Between January 1976 and July 1983, 217 patients with atrial septal defect underwent surgical repair at Children's Hospital. Thirty with a primum atrial septal defect and 26 who underwent cardiac catheterization elsewhere before being seen were excluded from analysis. Of the 161 remaining patients, 52 (31%) underwent preoperative cardiac catheterization, 38 because the physical examination was considered atypical for a secundum atrial septal defect and 14 because of a preexisting routine indication. One hundred nine (69%) underwent surgery without catheterization, with the attending cardiologist relying on clinical examination alone in 5, additional technetium radionuclide angiocardiography in 5, M-mode echocardiography in 13 and two-dimensional echocardiography in 43; both M-mode echocardiography and radionuclide angiography were performed in 24 and two-dimensional echocardiography and radionuclide angiography in 19. Since 1976, there has been a trend toward a reduction in the use of catheterization and use of one rather than two noninvasive or semiinvasive techniques for the detection of atrial defects. Of the 52 patients who underwent catheterization, the correct anatomic diagnosis was made before catheterization in 47 (90%). Two patients with a sinus venosus defect and one each with a sinus venosus defect plus partial anomalous pulmonary venous connection, partial anomalous pulmonary venous connection without an atrial septal defect and a sinoseptal defect were missed. Of 109 patients without catheterization, a correct morphologic diagnosis was made before surgery in 92 (84%). Nine patients with a sinus venosus defect, three with sinus venous defect and partial anomolous pulmonary venous connection, four with partial anomalous pulmonary venous return without an atrial septal defect and one with a secundum defect were incorrectly diagnosed.(ABSTRACT TRUNCATED AT 250 WORDS)

    It has been known that visualization is a user-preferred and more meaningful interface of information systems. To reduce the anxiety and uncertainty of patients, we transformed the sophisticated process of cardiac catheterization into visualized information. The Microsoft Visio 2003 and Excel 2003 with the VBA automation tool were used to design a process flow of Cardiac Catheterization. The results show the technical feasibility and potentials helpful for patient to realize the nursing process of cardiac catheterization. PMID:19593031

    Introduction. The aim of this study was to examine the incidence and risk factors of catheterization-related CI in the contemporary era, using diffusion-weighted magnetic resonance imaging. Methods. We retrospectively analyzed consecutive 84 patients who underwent MRI (magnetic resonance imaging) after 2.81 ± 2.4 days (mean ± SD) of catheterization via aortic arch. We categorized the patients by the presence or absence of acute CI determined by diffusion-weighted MRI and analyzed the incidence and predictors. Results. Of 84 patients that underwent MRI after catheterization, acute CI was determined in 27 (32.1%) patients. In univariate analysis, dyslipidemia, age, coronary artery disease, antiplatelet agents, number of catheters used, urgent settings, and interventional procedures were significantly different. Multivariate analysis revealed dyslipidemia (odds ratio [OR], 4.46; 95% confidence interval [CI], 1.41–16.03; p = 0.01), higher age (OR, 1.09; 95% CI, 1.007–1.19; p = 0.03), and the number of catheters used (OR, 2.21; 95% CI, 1.21–4.36; p = 0.01) as independent predictors of the incidence of catheterization-related acute CI. Conclusions. Dyslipidemia, higher age, and number of catheters used were independent predictors for acute CI after catheterization. These findings imply that managing dyslipidemia and comprehensive planning to minimize the numbers of catheters are important. PMID:27127790

  9. Comparison of Ultrasonography-Guided Central Venous Catheterization Between Adult and Pediatric Populations

    International Nuclear Information System (INIS)

    The purpose of this study was to compare the technical success and complication rates of ultrasonography-guided central venous catheterization between adult and pediatric patients which have not been reported previously. In a 4-year period, 859 ultrasonography-guided central vein catheterizations in 688 adult patients and 247 catheterizations in 156 pediatric patients were retrospectively evaluated. Mean age was 56.3 years (range, 18 to 95 years) for adults and 3.3 years (range, 0.1 to 16.3 years) for children. The preferred catheterization site was internal jugular vein in 97% of adults and 85% of children. The technical success rate, mean number of punctures, and rate of single wall puncture were 99.4%, 1.04 (range, 1-3), and 83% for adults and 90.3%, 1.25 (range, 1-5), and 49% for children, respectively. All the differences were statistically significant (p 0.05). Major complications such as pneumothorax and hemothorax were not seen in any group. In conclusion, ultrasonography-guided central venous catheterization has a high technical success rate, lower puncture attempt rate, and higher single wall puncture rate in adults compared to children. Complication rates are comparable in the two groups

  10. Selective catheterization of the brachiocephalic arteries via the right brachial artery

    International Nuclear Information System (INIS)

    Selective intra-arterial digital subtraction angiography of the brachiocephalic arteries using the right brachial artery approach was successfully performed for 169 of 173 patients, 33 of whom were outpatients. Catheterization was unsuccessful for four patients; two of them elderly hypertensive men with tortuos brachial arteries, and two of them middle-aged obese women for whom arterial puncture could not be performed. 4-F modified Simmons type catheters were used in this study. Selective catheterizations of both common carotid arteries were successfully performed in all but one patient, a woman whose aberrant right subclavian artery prevented bilateral common carotid arterial catheterizations. Selective catheterizations of the right vertebral and left subclavian arteries, though relatively difficult, were successfully performed in 84.2% and 93.9% of patients, respectively. The mean examination time for a four-vessel study was 24.3 min. No major complications were encountered. Thus, transbrachial selective catheterization of the brachiocephalic arteries proved to be safe, useful, and relatively easy to perform. (orig.)

    Full Text Available Objective: to describe the knowledge and significance of cardiac catheterization from cardiac patients’ perspective. Methods: descriptive and qualitative study of patients undergoing cardiac catheterization. Five categories were identified through content analysis. Results: knowledge of patients on cardiac catheterization proved to be limited; the subject was surrounded by lack of knowledge. Cardiac catheterization means a treatment for unblocking coronary arteries and it is confused with therapeutic purposes. There were reports of symptoms related to heart disease such as fatigue and chest pain and related to the exams such as worry, anxiety, depression, fear and restlessness generated, mainly, by expectations of the unknown. The majority of the respondents proved to be satisfied with the results of the exam, due to the discovery and treatment of heart diseases. Conclusion: cardiac catheterization means treatment and clearance of coronary arteries and it is confused with therapeutic purposes. Feelings such as worry, anxiety, fear and restlessness are described when patients are subjected to examination, generated mainly by expectations of the unknown.

  12. Bilateral catheterization of the inferior petrosal sinuses in 23 cases of ACTh-dependent hypercoarisolism

    International Nuclear Information System (INIS)

    Our purpose is to assess the results of catheterization of the inferior petrosal sinuses, a measure that is included in the diagnostic protocol for ACTH-dependent hypercortisolism. We analyzed retrospectively the data obtained for 23 patients (20 women and 3 men) subjected to this procedure. The test was complete (catheterization both inferior petrosal sinuses) in 21 patients (91%). The sensitivity in differentiating between Cushing's disease (n=21) and ectopic ACTH syndrome (n=21) was 95.2% after administration of CRH, with a specificity of 100%, and the positive predictive value for the intra pituitary localization of the micro adenoma (confirmed by histological study in 19 cases) was 61%. Catheterization of the inferior petrosal sinuses shows an elevated sensitivity and specificity in the diagnosis of Cushing's disease, although the positive predictive value for determining the intrapituitary localization of the adenoma is low.

    Outpatient cardiac catheterization is frequently performed, but the optimal recovery time after sheath removal has not been defined. Left heart catheterization was performed via the femoral artery utilizing 6 French catheters on 323 outpatients. One hundred thirty-five patients were randomized to ambulate at a mean of 2.5 hr (group 1) after puncture site compression, whereas 188 patients were randomized to ambulate at a mean of 4.1 hr (group 2). Telephone follow-up occurred within 48 hr. A small hematoma (< 5 cm) occurred in 2 (1.6%) patients in group 1 and in 4 (2.4%) patients in group 2. These results indicate that it is safe to ambulate patients 2.5 hr following 6 French diagnostic heart catheterization. PMID:9286529

  14. Microguidewire looping technique for superselective catheterization of the acute angled artery

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of microguidewire looping technique in superselective catheterization of the acute angled artery. Methods: Manipulating the microguide wire into a U shaped loop and simultaneous withdrawal of the microguidewire and microcatheter was performed when the tip of the microguidewire simultaneous got into the target artery and following by slowly and simultaneously withdrawing the microguidewire and microcatheter until the tip of the microguidewire entering into the target artery for a certain length and finally pushed the microcatheter into the target artery slowly. Results: Eighteen out of 21 patients with acute angled target artery were successfully catheterized through this approach with technical success rate of 86%, without any complications. Conclusions: Microguidewire looping technique is a feasible method for superselective catheterization of the acute angled artery when the routine approach failed. (authors)

    Simonsen, L; Bülow, J; Madsen, J

    A technique for catheterization of a vein draining abdominal subcutaneous tissue and a microdialysis technique that allows measurements of intercellular water concentrations in adipose tissue in humans have recently been described. In the present study, we compare the two techniques during an oral...... glucose load. In addition a technique using microdialysis for measurement of tissue oxygen and carbon dioxide tensions is described. Microdialysis and vein catheterization were performed in the same region on the abdomen, and the subcutaneous adipose tissue blood flow was measured by the local 133Xe...... agreement between the concentrations obtained by the two techniques with respect to glucose and glycerol, whereas lactate concentrations are very different. With regard to substrate fluxes calculated by Fick's principle, the catheterization technique is probably the most reliable, considering the numerous...

  16. Arterial thrombotic occlusions following percutaneous catheterization in infants and children: local thrombolytic therapy with urokinase

    International Nuclear Information System (INIS)

    Six cases of right external iliac and common femoral arterial thrombotic occlusions following transfemoral cardiac catheterization were found among the 117 infants and children with congenital heart disease. Physical findings of arterial thrombosis were lower extremity coldness and absence of femoral pulse, which appeared just after cardiac catheterization. Transcatheter local intrathrombotic infusion of Urokinase were done with 50000 IU bolus doses and 40000-50000 IU/h running doses. All 6 cases showed complete thrombolysis and re-establishment of femoral circulation. Three cases developed bleeding from arterial puncture sites, and were subsequently controlled properly by compression. No other complication was found. Our results suggest that local thrombolytic therapy with Urokinase is effective treatment method without significant complication for the infants and children with fresh thrombotic occlusions following cardiac catheterization and angiography

  17. Coil Embolization Treatment in Pulmonary Artery Branch Rupture During Swan-Ganz Catheterization

    International Nuclear Information System (INIS)

    Rupture of the pulmonary artery or one of its branches during Swan-Ganz catheterization is a complication that is rare but remains fatal in almost 50% of cases. The risk factors and mechanisms involved in the pathogenesis of this accident have been widely reported. Management is twofold: resuscitation procedures and specific medical or even surgical treatment. We report a case of pulmonary artery rupture occurring during Swan-Ganz catheterization that was treated by coil embolization. This technique, which is quick and simple to use, would appear to be very promising. This is the first case of successful emergency treatment of pulmonary artery rupture using an endovascular technique

  18. Ultrasound-guided compression repair of pseudoaneurysms and arteriovenous fistulae after arterial catheterization

    International Nuclear Information System (INIS)

    For the treatment of arterial lesions occuring after catheterization, ultrasound-guided compression repair (UGCR) has recently been introduced. Using this technique, we repeatedly attempted treatment of these lesions and assessed their characteristics, as seen on US. We prospectively studied 21 patients who had suffered arterial injury (16 pseudoaneurysms and five arteriovenous fistulae) during arterial catheterization. Occlusion of one pseudoaneurysm (PA) occurred spontaneously. UGCR was attempted in 20 cases involving arterial injury, including two which had occurred five months earlier. In six lesions, multiple attempts were necessary. (author). 29 refs., 3 tabs., 2 figs

    Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children undergoing cardiac catheterization due to various heart diseases were selected and urine and blood samples were taken at 0 hr, 6 hr, 24 hr, and 48 hr after cardiac catheterization. Until 48 hr after cardiac catheterization, there was no significant increase in serum creatinine level in all patients. Unlike urine kidney injury molecule-1, IL-18 and neutrophil gelatinase-associated lipocalin, urine liver-type fatty acid-binding protein (L-FABP) level showed biphasic pattern and the significant difference in the levels of urine L-FABP between 24 and 48 hr. We suggest that urine L-FABP can be one of the useful biomarkers to detect subclinical AKI developed by the contrast before cardiac surgery. PMID:25120320

    The aims of the present study were to develop a device for vaginal and transcervical catheterization in domestic cats, and to study cervical patency during the various stages of the oestrous cycle. Seventeen queens submitted for routine spaying were included in the study. A vaginal catheter was designed from a urinary catheter for dogs, to fit into the ventral vaginal fornix, and a 3.5 French tomcat catheter was used as an inner transcervical catheter. Cervical patency was studied by infusing 0.5 ml Urografin into the cranial vagina and taking X-rays of the queens after 5 min. The Urografin did not enter the uterus, even in the oestrous queens. Transcervical catheterization was then attempted. The correct placement of the intrauterine catheter was confirmed by injecting green food colour mixed with penicillin G and observing the presence of stain in the uterine horns during surgery. Catheterization was successful in 13 of 17 queens: six of nine in interoestrus, three of three in oestrus, one of two in metoestrus and three of three in the postpartum period. Transcervical catheterization is a non-invasive technique that is likely to improve the success rate of assisted feline reproduction, and is potentially a useful non-surgical technique for diagnosis and therapy of uterine diseases.

  3. Three-dimensional MR angiography for planning of hepatic arterial catheterization

    International Nuclear Information System (INIS)

    The aim of this study is to assess the potential utility of gadolinium-enhanced three-dimensional MR angiography (3D MR angiography) for arterial catheterization of hepatic tumor. Thirty-five consecutive patients with suspected abdominal tumors underwent MR angiography with a gadolinium-enhanced 3D fast gradient echo sequence. Visualization of the vascular tree of visceral arteries, and their variations, the apparent length of common hepatic artery (CHA), and the tilt of celiac trunk were prospectively evaluated by 3D MR angiography. The results were compared with those obtained by the conventional angiography. In 27 patients with hepatic tumors, the prospective planning with 3D MR angiography was compared with the actual catheterization. Celiac trunk, CHA, and superior mesenteric artery (SMA) were visualized on 3D MR angiography in all 35 patients. There was a significant linear correlation of the length of CHA and the tilt of SMA as measured by 3D MR angiography and conventional angiography (r=0.75, r=0.64, respectively). The 3D MR angiography provided useful clinical information for planning of arterial catheterization in all 27 patients with hepatic tumors. Thus gadolinium-enhanced 3D MR angiography is considered to be of value for the planning of arterial catheterization of hepatic tumor. (author)

  4. Catheterization of cerebral arteries under real-time MR imaging guidance: an experimental study in pigs

    International Nuclear Information System (INIS)

    Objective: To investigate the feasibility of catheterization of cerebral arteries under the real-time MR imaging guidance in experimental pigs. Methods: Ten small-sized female pigs were selected for this study. Via the femoral access, percutaneous catheterization with a 3 F active MR-tracking microcatheter was performed under real-time MRI guidance and the microcatheter was separately placed into bilateral ascending pharyngeal arteries. After the procedure, all the pigs were sacrificed and sent for pathologic examination. Gross pathologic examination of aortic arches, brachio-cephalic arteries, carotid arteries and ascending pharyngeal arteries was performed to search for the perforation and dissection. Results: MR angiography revealed that in pigs the bilateral ascending pharyngeal arteries formed an arteriolar network at the cranial base, supplying blood flow to the brain. Catheterization of ascending pharyngeal arteries from the femoral artery access was successfully performed in all 10 pigs with the help of real-time MR imaging-guidance. A single procedure took about 4-12 minutes. Macroscopically, no evidence of vascular injury of aortic arches, brachio-cephalic arteries, carotid arteries and ascending pharyngeal arteries was found. Conclusion: Under real-time MRI guidance the catheterization of cerebral arteries can be correctly and quickly accomplished in experimental pigs. (authors)

    Full Text Available Percutaneous transhepatic portal catheterization was performed in 68 cases of liver diseases in the 2 year period from 1978 to 1980. The Chiba University method was modified. Portal vein catheterization was successful in 61 cases (90%. Selective splenic vein catheterization was successful in 55 of the 61 cases (90% and selective superior mesenteric vein catheterization in 59 cases (97%. The liver was punctured an average of 4.6 times in order to successfully insert the catheter into the main portal vein, and the number of punctures was less than 10 in 57 of the 61 cases (93%. The portal vein pressure was 310+/-67 mm H2O in idiopathic portal hypertension (8 cases, 290+/-83 in liver cirrhosis (33 cases, 193+/-71 in chronic hepatitis (7 cases and 166+/-50 in fatty liver (4 cases. Portal vein pressure rose from 205+/-75 to 380+/-55 mm H2O in 11 cases after forced Valsalva maneuver. No major complications were encountered.

  6. Radiation exposure of pediatric patients and physicians during cardiac catheterization and balloon pulmonary valvuloplasty

    International Nuclear Information System (INIS)

    Thermoluminescent dosimeters were applied to various areas of 61 pediatric patients and physicians to measure radiation doses during routine cardiac catheterization and during 4 cases of balloon pulmonary valvuloplasty. Radiation doses were measured during chest roentgenography, fluoroscopy and cineangiography. Average skin dose to the chest was 121 microGy during chest x-ray, 5,182 microGy during catheterization and 641 mGy during valvuloplasty. For the eyes, thyroid and gonads of the patients, the exposure during routine catheterization was equal to 0.4, 6 and 0.2 chest x-rays, respectively. Radiation dose of the operator was 3 microGy for the eyes and 6 miCroGy in the thyroid. About 56% of the operator's dose could be reduced by thyroid shields, and 80% by lead aprons. The assistant received only 1 microGy outside the thyroid shield. Therefore, the authors have concluded that the patients dose during routine catheterization is largely based on our experimental results, but the dose is acceptable based on the risk factor analysis. The skin dose to the right lateral chest of the patient during valvuloplasty is extremely high, perhaps as high as the equivalent of 1,000 chest x-rays. Besides the clinical benefits of valvuloplasty, the long-term radiation-related hazards to the patient should be carefully monitored

    Background Femoral artery thrombosis is one of the most common complications of catheterizations in infants and young children. This study was conducted to investigate the feasibility and effectiveness of thrombolytic therapy for femoral artery thrombosis after left cardiac catheterization in children.Methods Thrombolytic therapy with urokinase was carried out in children with femoral artery thrombosis after left cardiac catheterization. Each patient was given a bolus injection of heparin (100 U/kg). A bolus of urokinase (30 000-100 000 U) was injected intravenously, and then a continuous infusion of 10 000-50 000 U/h was administered. Transcatheter thrombolysis was performed once previous procedures failed.Results Eight patients (aged (3.1±2.3) years (8 months to 7 years), body weight (13.1±4.2) kg (7 to 20 kg)) presented lower limbs ischemia alter left cardiac catheterizations was performed. Seven patients accepted thrombolytic therapy with urokinase. In 5 patients, peripheral intravenous thrombolysis was successful with restoration of a normal pulse. In the other 3 cases, peripheral intravenous thrombolysis failed, followed by successful transcatheter thrombolysis. The average duration of therapy was (7.25±5.31) hours (1-17 hours). The average doses of heparin and urokinase were (1600±723) U (800-3000 U) and (268 571±177 240) U (50 000-500 000 U), respectively. There were no statistically significant differences in partial thromboplastin time before and during urokinase therapy ((40.6±22.3) to (49.9±39.2) seconds). However, the prothrombin time was significantly longer ((12.7±9.58) to (48.1±18.6) seconds, P<0.05). Patency of the target vessel was evaluated in all the patients for 2 weeks and no occlusion recurred.Conclusion Thrombolytic therapy with urokinase is a safe and useful modality in children with femoral artery thrombosis after left cardiac catheterization.

    Full Text Available Abstract Background There is variation in cardiac catheterization utilization across jurisdictions. Previous work from Alberta, Canada, showed no evidence of a plateau in the yield of high-risk disease at cardiac catheterization rates as high as 600 per 100,000 population suggesting that the optimal rate is higher. This work aims 1 To determine if a previously demonstrated linear relationship between the yield of high-risk coronary disease and cardiac catheterization rates persists with contemporary data and 2 to explore whether the linear relationship exists in other jurisdictions. Methods Detailed clinical information on all patients undergoing cardiac catheterization in 3 Canadian provinces was available through the Alberta Provincial Project for Outcomes Assessment in Coronary Heart (APPROACH disease and partner initiatives in British Columbia and Nova Scotia. Population rates of catheterization and high-risk coronary disease detection for each health region in these three provinces, and age-adjusted rates produced using direct standardization. A mixed effects regression analysis was performed to assess the relationship between catheterization rate and high-risk coronary disease detection. Results In the contemporary Alberta data, we found a linear relationship between the population catheterization rate and the high-risk yield. Although the yield was slightly less in time period 2 (2002-2006 than in time period 1(1995-2001, there was no statistical evidence of a plateau. The linear relationship between catheterization rate and high-risk yield was similarly demonstrated in British Columbia and Nova Scotia and appears to extend, without a plateau in yield, to rates over 800 procedures per 100,000 population. Conclusions Our study demonstrates a consistent finding, over time and across jurisdictions, of linearly increasing detection of high-risk CAD as population rates of cardiac catheterization increase. This internationally-relevant finding

    DEFF Research Database (Denmark)

    Simonsen, L; Bülow, J; Madsen, J

    A technique for catheterization of a vein draining abdominal subcutaneous tissue and a microdialysis technique that allows measurements of intercellular water concentrations in adipose tissue in humans have recently been described. In the present study, we compare the two techniques during an oral...... glucose load. In addition a technique using microdialysis for measurement of tissue oxygen and carbon dioxide tensions is described. Microdialysis and vein catheterization were performed in the same region on the abdomen, and the subcutaneous adipose tissue blood flow was measured by the local 133Xe...... washout method. The results show that subcutaneous adipose tissue gas tensions are on level with gas tensions measured in abdominal venous blood. Comparison of metabolite concentrations measured in the venous blood and venous blood concentrations calculated from microdialysis data shows that there is good...

    Full Text Available The bases and technical cares for the neuro-radiological study of the aorto-cervical and spinal vessels employing the retrograde catheterization according to Seldinger technic and with the Odman-Ledin catheters are reported. The authors recommend type II neuroleptanalgesia as anesthesical sedative and the use of percutaneous punction of the femoral artery or, by choice, of the axilar or humeral artery. For the selective catheterization by femoral via, they make previously an aortography, in order to know the anatomy of the supra-aortic vessels, with control through the image-inten-sifier or fluoroscopy. They employ manual injection for the study of the supra-aortic vessels and a Gidlung injector for the contrast of the ascending aorta. Complications are discussed.

    AIM: To assess the catheterization-associated complications during intraperitoneal chemotherapy (IPCT) for advanced gastric cancer.METHODS: From 1998 to 2002, 80 patients with advanced gastric cancer received a total of 320 courses of IPCT using a large bore central venous catheter and associated complications were analyzed.RESULTS: Catheterization-associated complications occurred in 11 of the 80 patients (13.8%), including abdominal pain caused by catheter in 2 cases (0.63%), insertion failure in 2 cases (0.63%), bowel perforation in 1 case (0.31%)and abdominal pain during chernotherapy in 6 cases (1.88%).No serious complications required surgical intervention.CONCLUSION: IPCT using central venous catheters can be performed safely and simply without severe associated complications.

  15. Radiologic fallopian tube catheterization for diagnosis and treatment of proximal tubal obstruction

    International Nuclear Information System (INIS)

    Seventy-five infertile women in whom proximal fallopian tube obstruction had been demonstrated by conventional hysterosalpingography were managed by means of fluoroscopic transcervical fallopian tube catheterization techniques. The procedure helped avoid surgery for diagnosis and/or treatment of proximal tubal obstruction in 71 women (95%). In 32 patients who had patent tube(s) following the procedure, 15 pregnancies have occurred, 14 intrauterine and one tubal (follow-up, 6 months). Fifteen patients had follow-up studies after recanalization, and 19 of 23 tubes remained patent (83%). Fluoroscopic fallopian tube catheterization improves diagnosis of fallopian tube disease and is a low-cost, nonsurgical treatment for infertility caused by proximal fallopian tube obstruction

  16. Possibilities of reducing the radiation dose to patients in the cardiac catheterization laboratory

    International Nuclear Information System (INIS)

    There are possible approaches to radiation dose reduction in cardiac catheterization, both for the operational modus of fluoroscopy and cinematography. An initial study in 15 patients treated with diagnostic cardiac catheterization or PTCA has shown that the cine-technique contributes at least half of the dose-area product accumulated during the entire examination. The radiation dose administered by the cinematographic technique per minute of diagnostic examination is approx. between 5 times and 13 times higher than the dose contributed by fluoroscopy. The paper discusses various possibilities of dose reduction. Studies performed by the authors have shown that additional 0.3 copper filters will reduce the dose to the skin to less than half of the usually applied skin dose. (orig.)

    2010-10-01

    Full Text Available Abstract Introduction Central venous access devices are widely used in hospital practice. Complications associated with their use are well described and reviewed. In this paper, we report a former complication that in turn created a new complication during a standardized procedure. Case presentation We report the case of an 81-year-old Caucasian woman requiring total parenteral nutrition due to a high-debt enterocutaneous fistula. In a previous right subclavian catheterization a fragmentation of the tip of the catheter, probably not recognized at the time, provoked an extrinsic compression of the vessel. Conclusion Fragmentation of a central venous catheter is a possible complication of catheterization and can be missed. Control of a catheter is imperative after its removal, even if not always practiced.

  19. The value of cardiac catheterization and cineangiography in infantile lobar emphysema

    International Nuclear Information System (INIS)

    Lobar emphysema is an uncommon cause of respiratory distress in infancy. Congenital heart disease is seen in about 20% of the patients with infantile (congenital) lobar emphysema. We described six infants with lobar emphysema. In three of them a congenital heart disease was demonstrated by cardiac catheterization and cineangiography; two had a tetralogy of Fallot with right aortic arch and the third infant a ventricular septal defect. The pulmonary angiography showed stretching of the arteries with very poor filling of the peripheral arteries and a characteristic smaller pulmonary vein in the affected lobe. In all the six patients the pulmonary artery pressure was normal. All the patients underwent lobectomy with good results. We feel that a preoperative cardiac catheterization and cineangiography is of value in this very sick group of infants. (orig.)

    The aim of this study was to determine whether the natural course of urethral stricture disease could be modified following urethrotomy by teaching patients intermittent self-catheterization. Preliminary results in 42 patients show that postoperative urine flow rates can be maintained if this method of 'low-friction' catheterization is adopted. The technique has been well received by an elderly group of patients and can be recommended for wider use.

  2. Is there possibility of radioinduced deterministic effect during procedures of cardiac catheterism in patients?

    International Nuclear Information System (INIS)

    In this work were presented 22 cases of radiation deterministic effect in patients submitted to catheterism procedures by means of X-fluoroscope. Evaluation of the results suggest that the most of patients receive potential skin entrance doses over 2 Gy and some of them may have received doses over 12 Gy. At these doses, radiation induced erythema, ulceration and necrosis are all possible complications if the same entrance skin surface is exposed for the duration of the procedure

  3. Thrombus Formation After Percutaneous Catheterization and Manual Compression of the Femoral Artery in Heparinized Sheep

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the angiographic and histopathologic changes in the superficial femoral artery (SFA) in heparinized sheep shortly after catheterization with an 8-Fr sheath and manual compression hemostasis either with standard manual compression (SMC) or with the use of a procoagulant chitosan-based HemCon Bandage. The evaluation was done in 38 SFAs of 19 heparinized (100 mg/kg) sheep. After a 5-min catheterization with an 8-Fr sheath, a 5-min compression was applied. Follow-up angiograms to evaluate hemostasis were done immediately after release of compression and then at 2.5-min intervals until no extravasation was present. Compression was reapplied between angiograms. Final angiograms were performed approximately 30 min after hemostasis and after 3 min of passive flexion and extension of sheep hind limbs. Sheep were then euthanized and SFA specimens with surrounding tissues excised for histopathologic evaluation. Both types of compression caused similar changes in the catheterized SFAs. Follow-up angiograms showed mild arterial narrowing in 14 SFAs and intraluminal clots in 9 SFAs. Histology revealed periarterial hematoma in all 38 specimens. Intraluminal thrombi consisting predominantly of platelets and fibrin were present in 32 SFAs. Their size varied from superficial elevations (8 arteries) to medium-sized, 1- to 2-mm, polypoid protrusions (15 arteries) to large polypoid clots, 3-4 mm long (9 arteries). In six SFAs, the arterial access sites were not included in the obtained specimens. In conclusion, hemostasis with manual compression is achieved in the acute phase by formation of a predominantly platelet-fibrin thrombus occluding the arterial wall access site and often extending significantly into the arterial lumen. The healing process of arterial access sites should be explored several days after catheterization.

    2014-06-01

    Purpose: Diagnosis and treatment of cardiovascular disease in the cardiac catheterization laboratory is often aided by a multitude of imaging technologies. The purpose of this work is to highlight the contributions to patient care offered by the various imaging systems used during cardiovascular interventional procedures. Methods: Imaging technologies used in the cardiac catheterization lab were characterized by their fundamental technology and by the clinical applications for which they are used. Whether the modality is external to the patient, intravascular, or intracavity was specified. Specific clinical procedures for which multiple modalities are routinely used will be highlighted. Results: X-ray imaging modalities include fluoroscopy/angiography and angiography CT. Ultrasound imaging is performed with external, trans-esophageal echocardiography (TEE), and intravascular (IVUS) transducers. Intravascular infrared optical coherence tomography (IVOCT) is used to assess vessel endothelium. Relatively large (>0.5 mm) anatomical structures are imaged with x-ray and ultrasound. IVUS and IVOCT provide high resolution images of vessel walls. Cardiac CT and MRI images are used to plan complex cardiovascular interventions. Advanced applications are used to spatially and temporally merge images from different technologies. Diagnosis and treatment of coronary artery disease frequently utilizes angiography and intra-vascular imaging, and treatment of complex structural heart conditions routinely includes use of multiple imaging modalities. Conclusion: There are several imaging modalities which are routinely used in the cardiac catheterization laboratory to diagnose and treat both coronary artery and structural heart disease. Multiple modalities are frequently used to enhance the quality and safety of procedures. The cardiac catheterization laboratory includes many opportunities for medical physicists to contribute substantially toward advancing patient care.

    Full Text Available Background It is believed that healthcare staff play an important role in minimizing complications related to urethral catheterization. The purpose of this study was to determine whether or not healthcare staff complied with the standards for urethral catheterization. Methods This study was conducted in Imam Reza teaching hospital, Tabriz, Iran, from July to September 2013. A total of 109 catheterized patients were selected randomly from surgical and medical wards and intensive care units (ICUs. A questionnaire was completed by healthcare staff for each patient to assess quality of care provided for catheter insertion, while catheter in situ, draining and changing catheter bags. Items of the questionnaire were obtained from guidelines for the prevention of infection. Data analysis was performed with SPSS 16. Results The mean age of the patients was 50.54 ± 22.13. Of the 109 patients, 56.88% were admitted to ICUs. The mean duration of catheter use was 15.86 days. Among the 25 patients who had a urinalysis test documented in their hospital records, 11 were positive for urinary tract infection (UTI. The lowest rate of hand-washing was reported before bag drainage (49.52%. The closed drainage catheter system was not available at all. Among the cases who had a daily genital area cleansing, in 27.63% cases, the patients or their family members performed the washing. In 66.35% of cases, multiple-use lubricant gel was applied; single-use gel was not available. The rate of documentation for bag change was 79%. Conclusion The majority of the guideline statements was adhered to; however, some essential issues, such as hand hygiene were neglected. And some patients were catheterized routinely without proper indication. Limiting catheter use to mandatory situations and encouraging compliance with guidelines are recommended.

  7. Direct measurement of a patient's entrance skin dose during pediatric cardiac catheterization

    International Nuclear Information System (INIS)

    Children with complex congenital heart diseases often require repeated cardiac catheterization; however, children are more radiosensitive than adults. Therefore, radiation-induced carcinogenesis is an important consideration for children who undergo those procedures. We measured entrance skin doses (ESDs) using radio-photoluminescence dosimeter (RPLD) chips during cardiac catheterization for 15 pediatric patients (median age, 1.92 years; males, n = 9; females, n = 6) with cardiac diseases. Four RPLD chips were placed on the patient's posterior and right side of the chest. Correlations between maximum ESD and dose-area products (DAP), total number of frames, total fluoroscopic time, number of cine runs, cumulative dose at the interventional reference point (IRP), body weight, chest thickness, and height were analyzed. The maximum ESD was 80 ± 59 (mean ± standard deviation) mGy. Maximum ESD closely correlated with both DAP (r = 0.78) and cumulative dose at the IRP (r = 0.82). Maximum ESD for coiling and ballooning tended to be higher than that for ablation, balloon atrial septostomy, and diagnostic procedures. In conclusion, we directly measured ESD using RPLD chips and found that maximum ESD could be estimated in real-time using angiographic parameters, such as DAP and cumulative dose at the IRP. Children requiring repeated catheterizations would be exposed to high radiation levels throughout their lives, although treatment influences radiation dose. Therefore, the radiation dose associated with individual cardiac catheterizations should be analyzed, and the effects of radiation throughout the lives of such patients should be followed. (author)

  10. [Acute urinary retention: a few simple rules for a successful catheterization].

    Science.gov (United States)

    Birkhäuser, Frédéric D; Studer, Urs E

    2015-01-01

    Acute urinary retention is a common emergency condition in elderly men. Transurethral and suprapubic catheterization are easy and safe procedures provided that a few simple rules are followed. Primarily, a transurethral catheter is placed if there is no urethral injury or stricture. Local anaesthesia of the urethra up to the sphincter region and a well-stretched penis warrant an atraumatic insertion of the catheter into the bladder. The use of a thick catheter with a round tip or of a catheter with a bended tip under rectal guidance facilitate the insertion of the catheter in difficult conditions. Alternatively, a suprapubic catheterization can be performed provided that no contraindication such as history or suspicion of transitional cell carcinoma is present. Optimal interventional conditions using ultrasound-guidance are mandatory in patients after abdominal surgery and with hemorrhagic diathesis in view of a safe and straight-forward placement of the suprapubic catheterization. In case of persistent bleeding after insertion of a suprapubic catheter, the suprapubic catheter should be replaced by one with a balloon blocked and kept under tension for several minutes.

    2016-04-01

    Intermittent catheterization is considered the standard of care in most neurologic patients with lower urinary tract disorders. However, in this context, genitourinary tract infection and urethral trauma represent specific challenges. Such conditions have been found to significantly deteriorate quality of life and complicate subsequent treatments. Only optimal prevention associated with appropriate treatment allows for the long-term continuation of such bladder management. Here, we discuss the diagnosis and therapeutic and preventive approaches associated with genitourinary tract infection and urethral trauma in this specific population. This "state-of-the-art" article results from a literature review (MEDLINE articles and scientific society guidelines) and the authors' experience. It was structured in a didactic way to facilitate comprehension and promote the implementation of advice and recommendations in daily practice. Genitourinary tract infection and urethral trauma associated with intermittent catheterization in neurologic patients should be managed with a global approach, including patient and caregiver education, optimal catheterization with hydrophilic-coated or pre-lubricated catheters and adequate use of antibiotic therapy.

    Full Text Available Background and Objectives: Most patients experience moderate to severe anxiety before cardiac catheterization. This study aimed to investigate the effect of Rosa aromatherapy on anxiety before cardiac catheterization. Methods: In this randomized controlled trial, 60 patients who met the inclusion criteria were conveniently sampled and randomly allocated to the experimental and control groups. Patients in the control group received routine care. In the experimental group, patients received routine care and Rosa aromatherapy for eighteen minutes. The level of anxiety was measured immediately before, and after the treatment. Results: In the stages before and after the study, there were no significant differences between the two groups in the terms of the mean scores of state and total anxiety. However, the mean score of trait anxiety in the experimental group was significantly lower than the control group. Furthermore, there was no significant difference between pre- and post-treatment in both groups. Conclusion: Most of the patients experience moderate to severe anxiety before cardiac catheterization. The findings of this study demonstrate that aromatherapy, as administered in this study, is not beneficial.

    Background Sex and neighborhood socioeconomic status (nSES) may independently affect the care and outcomes of acute coronary syndromes (ACS), partly through barriers in timely access to cardiac catheterization. We sought to determine whether sex modifies the association between nSES, and the receipt of cardiac catheterization and mortality following an ACS in a universal healthcare system. Methods and Results We studied 14,012 ACS patients admitted to cardiology services between April 18, 2004 and December 31, 2011 in Southern Alberta, Canada. We used multivariable logistic regression to compare the odds of cardiac catheterization within 2 and 30 days of admission and the odds of 30-day and 1-year mortality for men and women by quintile of neighborhood median household income. Significant relationships between nSES and the receipt of cardiac catheterization and mortality after ACS were detected for women but not men. When examined by nSES, each incremental decrease in neighborhood income quintile for women was associated with a 6% lower odds of receiving cardiac catheterization within 30 days (p=0.01) and a 14% higher odds of 30-day mortality (p=0.03). For men, each decrease in neighborhood income quintile was associated with a 2% lower odds of receiving catheterization within 30 days (p=0.10), and a 5% higher odds of 30-day mortality (p=0.36). Conclusions Associations between nSES and receipt of cardiac catheterization and 30-day mortality were noted for women but not men in a universal healthcare system. Care protocols designed to improve equity of access to care and outcomes are required, especially for low-income women. PMID:24895450

  14. Hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy for unresectable primary liver cancer

    International Nuclear Information System (INIS)

    Objective: To compare the effect of hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy and hepatic artery ligation (group A, 65 patients) with conventional fractionation radiation combined with hepatic artery catheterization chemotherapy and hepatic artery ligation (group B, 65 patients) for unresectable primary liver cancer. Methods: A total to 130 stage II primary liver patients confirmed by pathology and evaluated as unresectable by exploratory laparotomy were divided evenly into group A and group B by the sequence of exploration. The two groups were comparable in age, sex, tumor type and positive fetal protein (AFP). Group A patients were treated by hepatic artery chemotherapy (PDD, 10 mg/day) 6 day a week with hepatic artery ligation followed by hyperfractionation radiotherapy (250 cGy/f, bid) 3 days a week with the scheme alternated weekly. Group B patients were treated by conventional fractionation radiotherapy with the same scheme of chemotherapy as group A. The total dose of PDD and radiotherapy for both groups were 240 mg and 45 Gy. Results: The AFP level was reduced to half in 89.7% of patients in group A and 67.6% in group B. The 1-, 3- and 5-year survival rates were 90.8%, 63.1%, 23.1% for group A and 73.9%, 41.5%, 9.2% for group B, the difference was statistically significant (P 0.05). Conclusions: Hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy and hepatic artery ligation is an effective and reasonable therapeutic scheme for unresectable liver cancer. It can effectively relieve symptoms, reduce the tumor, increase second surgical resection rate and prolong the survival. At the same time, the operation is simple and relatively easy

    Background Sedatives and analgesics are often administered to achieve conscious sedation for diagnostic and therapeutic procedures. Appropriate concerns have been raised regarding post procedure delirium related to peri-procedural medication in the elderly. The objective of this study was to investigate the effect of premedication on new onset delirium and procedural care in elderly patients. Methods Patients≥70 years old and scheduled for elective cardiac catheterization were randomly assigned to receive either oral diphenhydramine and diaze-pam (25 mg/5 mg) or no premedication. All patients underwent a mini mental state exam and delirium assessment using confusion assess-ment method prior to the procedure and repeated at 4 h after the procedure and prior to discharge. Patients’ cooperation during the procedure and ease of post-procedure were measured using Visual Analog Scale (VAS). The degree of alertness was assessed immediately on arrival to the floor, and twice hourly afterwards using Observer’s Assessment of Alertness/Sedation Scale (OAA/S). Results A total of 93 patients were enrolled. The mean age was 77 years, and 47 patients received premedication prior to the procedure. None of the patients in either group developed delirium. Patients’ cooperation and the ease of procedure was greater and pain medication requirement less both during and after the procedure in the pre-medicated group (P < 0.05 for both). Nurses reported an improvement with patient management in the pre-medicated group (P=0.08). Conclusions In conclusion, premedication did not cause delirium in elderly patients undergoing cardiac catheterization. The reduced pain medication requirement, perceived procedural ease and post procedure management favors premedication in elderly patients undergoing cardiac catheterization.

  16. Does ultrasound-guided lidocaine injection improve local anaesthesia before femoral artery catheterization?

    International Nuclear Information System (INIS)

    Aim: To present the results of a prospective, randomized, single-centre study investigating local anaesthesia before percutaneous common femoral artery (CFA) puncture and catheterization with the use of ultrasound-guided injection of lidocaine versus standard infiltration by manual palpation. Materials and methods: Patients scheduled to undergo diagnostic or therapeutic transfemoral catheter-based procedures gave informed consent and were randomized in two groups. In the first arm local anaesthesia with lidocaine hydrochloride 1% was performed under ultrasound guidance (group U/S), while in the second arm the standard method of manual artery palpation was applied (group M). In both groups, subsequent CFA catheterization was achieved under ultrasound guidance. The primary study endpoint was peri-procedural pain level evaluated with a visual-analogue scale (VAS score 0-10). Results: Between January 2009 and 2010, 200 patients (161 men, mean age 63 ± 12 years) were equally assigned to each group without any significant differences in baseline demographics. Patients in group U/S experienced significantly less pain during CFA catheterization in comparison with group M with a difference of three points in mean VAS score reported (1.6 ± 1.6 versus 4.6 ± 1.9, p < 0.0001). In addition, significantly less volume of lidocaine was used in group U/S compared to group M (16 ± 2.7 versus 19 ± 0.8 ml, p < 0.001).Total vascular access time was similar in both groups (4.4 ± 1.3 versus 4.5 ± 1.3 min). Overall complications included two small groin haematomas in each group. Conclusion: Ultrasound-guided local anaesthesia of the CFA prior to percutaneous transcatheter procedures is safe and achieves superior levels of analgesia with minimal patient pain and discomfort compared to the standard method of manual palpation.

    Aim: To present the results of a prospective, randomized, single-centre study investigating local anaesthesia before percutaneous common femoral artery (CFA) puncture and catheterization with the use of ultrasound-guided injection of lidocaine versus standard infiltration by manual palpation. Materials and methods: Patients scheduled to undergo diagnostic or therapeutic transfemoral catheter-based procedures gave informed consent and were randomized in two groups. In the first arm local anaesthesia with lidocaine hydrochloride 1% was performed under ultrasound guidance (group U/S), while in the second arm the standard method of manual artery palpation was applied (group M). In both groups, subsequent CFA catheterization was achieved under ultrasound guidance. The primary study endpoint was peri-procedural pain level evaluated with a visual-analogue scale (VAS score 0-10). Results: Between January 2009 and 2010, 200 patients (161 men, mean age 63 {+-} 12 years) were equally assigned to each group without any significant differences in baseline demographics. Patients in group U/S experienced significantly less pain during CFA catheterization in comparison with group M with a difference of three points in mean VAS score reported (1.6 {+-} 1.6 versus 4.6 {+-} 1.9, p < 0.0001). In addition, significantly less volume of lidocaine was used in group U/S compared to group M (16 {+-} 2.7 versus 19 {+-} 0.8 ml, p < 0.001).Total vascular access time was similar in both groups (4.4 {+-} 1.3 versus 4.5 {+-} 1.3 min). Overall complications included two small groin haematomas in each group. Conclusion: Ultrasound-guided local anaesthesia of the CFA prior to percutaneous transcatheter procedures is safe and achieves superior levels of analgesia with minimal patient pain and discomfort compared to the standard method of manual palpation.

  18. Complete hemodynamic evaluation of patients with aortic regurgitation by outpatient right heart catheterization and digital subtraction angiography

    International Nuclear Information System (INIS)

    The aim of this study was to demonstrate that total hemodynamic evaluation of patients with aortic regurgitation can be performed on an outpatient basis by combining right heart catheterization with digital subtraction angiography (DSA). Thirteen patients with severe aortic regurgitation were catheterized as outpatients, without premedication. The pulmonary artery was entered percutaneously through the femoral vein. Cardiac output and stroke volume were measured by the indicator dilution method by injection into the inferior vena cava and sampling from the pulmonary artery. The regurgitant fraction was obtained by subtracting the indicator stroke volume from the angiographic left ventricular stroke volume. The following results are expressed as mean ± SD. Ejection fraction (%) = 54 ± 6; end diastolic volume index (ml) = 228 ± 40; end systolic volume index (ml) = 198 ± 51 and regurgitant fraction (%) = 59 ± 7 while the pulmonary wedge pressure (mmHg) = 10 ± 3. In 4 cases, comparison with recent catheterization data showed good agreement for all parameters (r = 0.90), except ejection fraction (r = 0.75). In conclusion, this simplified catheterization method using digital subtraction enables the procedure to be done on an outpatient basis. All essential hemodynamic data can be obtained by right heart catheterization. (author)

    Full Text Available Coronary malperfusion due to type A aortic dissection is a life-threatening condition where timely recognition and treatment are mandatory. A 77-year-old woman underwent an acute evolving type A aortic dissection mimicking acute myocardial infarction. Two pathophysiologic mechanisms are discussed: either thrombosis migrating from a previously treated giant aneurism of proximal left anterior descending or a local arterial complication due to left main stenting. Recognition of these occurrences in the catheterization laboratory is important to look immediately for surgery.

    Central venous catheterization is routinely required in a wide range of clinical situations such as hemodynamic monitoring, delivery of blood products and drugs, hemodialysis, total parental nutrition, and management of perioperative fluids. Pseudoaneurysms account for 4% of all innominate artery aneurysms. Clinical presentation may include airway and neurological compression, chest pain, mediastinal syndrome, upper limb ischemia, and hemodynamic instability. We report what we believe is the first documented case of a successful endovascular stent-graft repair of an innominate artery iatrogenic pseudoaneurysm. PMID:21193466

    Dexmedetomidine is an α-2 agonist with a sedative and cardiopulmonary profile that makes it an attractive anesthetic in pediatric cardiac patients. Cardiac transplant patients may suffer from acute cellular rejection of the cardiac conduction system and, therefore, are at an increased risk of the electrophysiological effect of dexmedetomidine. We present such a patient who had a cardiac arrest while receiving dexmedetomidine during cardiac catheterization. Because acute cellular rejection of the cardiac conduction system is difficult to diagnose, dexmedetomidine should be used with caution in pediatric heart transplant patients. PMID:26721807

    Full Text Available Abstract Introduction Conversion of multiple hepatic arteries into a single vascular supply is a very important technique for repeat hepatic arterial infusion chemotherapy using an implanted port catheter system. Catheterization of a replaced left hepatic artery arising from a left gastric artery using a percutaneous catheter technique is sometimes difficult, despite the recent development of advanced interventional techniques. Case presentation We present a case of a 70-year-old Japanese man with multiple hepatocellular carcinomas in whom the replaced left hepatic artery arising from the left gastric artery needed to be embolized. After several failed procedures, the replaced left hepatic artery was successfully catheterized and embolized with a microcatheter and microcoils via the right gastric artery through the anastomosis. Conclusion A replaced left hepatic artery arising from a left gastric artery can be catheterized via a right gastric artery by using the appropriate microcatheter and microguidewires, and multiple hepatic arteries can be converted into a single supply.

  4. X-ray diagnosis and treatment for severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease

    International Nuclear Information System (INIS)

    Objective: To study the radiological features of severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease so as to make early diagnosis and treatment. We also intend to find the mechanism of these complications. Methods: A total of 9 pediatric cases with severe respiratory complications during cardiac catheterizations were included in the study. The clinical manifestations, radiological features, and corresponding treatments were reviewed. Results: Most of the cases had severe hypoxia, with 6 cases presenting with bradycardia. Opacification of two lung fields was found in 7 cases, pulmonary edema in 1 case, and atelectasis of the upper right lung in 1 case. With intubation, oxygen inhalation and administration of certain drugs, all cases were saved except 1 case with pulmonary edema. Conclusion: Severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease are emergent and critical, and they often presented with various manifestations. Early diagnosis and correct treatment are the key to successful salvage. (authors)

    Full Text Available Bachground & aim: Pulse oximetry and cardiac catheterization are concerned in the treatment of children with congenital heart disease. Diagnosis of arterial oxygen saturation in patients with congenital heart disease (CHD can be used to assess and manage their effecacy. The purpose of this study was to compare pulse oximetry and cardiac catheterizations in treatment manage of children with congenital heart disease. Methods: In the present cross sectional study, 110 patients with cyanic and non syani heart disease were studied undergoing right and left heart catheterization by pulse oximetry of index finger and simultaneously, oxygen saturation was measured by cardiac catheterization. Data were analyzed with SPSS software by using Pearson correlation and linear regression. Results: A significant correlation was seen between arterial oxygen saturation measured by pulse oximetry and arterial oxygen saturation (p<0.0001 as well as heart rate, electrocardiogram and pulse oximetry (p<0.0001 respectively. Furthermore, the presence of cyanosis (p=0.001, digital clubbing of the fingers ((p=0.001, low oxygen saturation in the superior vena cava and right atrium (p=0.002 can reduce the accuracy of pulse oximetry for detection of arterial oxygen saturation. The mean right atrial pressure can effect on accuracy of pulse oximetry to detect heartbeat (p=0.034. Maximum sensitivity and specificity for detection of pulse oximetry oxygen saturation was 88 % and 88 heart rate per minute. Conclusion: Pulse oximetric is a useful tool for estimating the arterial oxygen saturation and heart rate in children with congenital heart disease (CHD and is a non-invasive method in comparison with cardiac catheterization.

    Full Text Available Abstract Background Significant bacteriuria (SBU and urinary tract infections (UTIs are common in patients with spina bifida and neuropathic detrusor sphincter dysfunction. Laboratory agar plated culture is the gold standard to establish SBU. It has the disadvantage of diagnostic and subsequent therapeutic delay. Leukocyte esterase tests (LETs and dip slides proved to be useful in the general populations to exclude SBU and UTI. The aim of this study was to evaluate the reliability of LET and dip slide in children with spina bifida without symptoms of UTI. The reliability in children with asymptomatic SBU was not studied before. Methods In one hundred and twelve children with spina bifida on clean intermittent catheterization LETs and dip slides were compared with laboratory cultures. Both tests and agar plated cultures were performed on catheterized urine samples. The hypothesis was that the home tests are as accurate as laboratory cultures. Results A SBU was found in 45 (40% of the 112 laboratory cultures. A negative LET excluded SBU (negative predictive value 96%, while a positive LET had a positive predictive value of 72%. The false positive rate was 28%. Dip slide determination of bacterial growth had no added value, other than serving as transport medium. Conclusions In spina bifida children, leukocyte esterase testing can be used to exclude significant bacteriuria at home, while dip slide tests have no added value to diagnose or exclude significant bacteriuria.

    Primary pancreatic hydatid cysts are rare and its percutaneous treatment and catheterization technique has, to the best of our knowledge, not been published in literature. A 33-year-old male patient who presented with abdominal pain was evaluated by ultrasonography (US) and computed tomography examinations. Both examinations revealed a cyst in the neck of the pancreas. After the administration of albendazole chemoprophylaxis, the patient underwent diagnostic puncture showing high pressure spring water which harbored the scoleces and was treated percutaneously by the catheterization technique. In this technique, first the cyst was punctured, the fluid content aspirated, the radiocontrast material injected to see possible fistulisation, and then re-aspirated. The 20% hypertonic saline solution was injected and re-aspiration was performed to the best of our abilities, followed by the insertion of a catheter for drainage of the remaining non-aspiratable fluid content. At follow-up examination, the cyst was not visible on US after 6 months. There was no evidence of cyst recurrence or dissemination after 18 months at serologic and imaging follow-up.

    The need to bypass to the brachial artery is rare. Over a five-year period, 16 patients had suffered iatrogenic post-catheterization injuries of the upper extremity. We have performed 16 bypasses, in 16 patients, mean age was 65 years (range 47-75), to the brachial artery originating from an artery proximal to the shoulder joint. In all cases, the axillary artery was the donor artery. All bypasses were created by using the cephalic vein with the in situ technique and distal anastomoses were made to a distance-free section of brachial artery. No operative mortality, neurological complications or major upper-extremity amputation was associated with the procedure. Life-long-conduit analysis showed 75% patency in the five-year period. After iatrogenic post-catheterization trauma of arterial system of upper extremity, bypasses from axillary to brachial artery with the cephalic vein with the in situ technique is a safe operation with satisfactory long-term patency.

    Introduction: Central venous catheter placement is an effective alternative vascular access for dialysis in patients with chronic renal failure. The purpose of this study was to evaluate the insertion of central venous catheters for hemodialysis using angiographic techniques in patients with previous multiple catheterizations in terms of efficacy of the procedure and early complications. Materials and methods: Between 2008 and 2010, the vascular access team of our hospital placed 409 central venous catheters in patients with chronic renal failure. The procedure was performed using the Seldinger blind technique. In 18 (4.4%) cases it was impossible to advance the guidewire, and so the patients were transported to the angiography suite. Results: Using the angiographic technique, the guidewire was advanced in order to position the central venous catheter. The latter was inserted into the subclavian vein in 12 (66.6%) cases, into the internal jugular vein in 4 (22.2%) and into the femoral vein in 2 (11.1%) cases. There was only one complicated case with severe arrhythmia in 1 (5.5%) patient. Conclusion: Our results suggest that insertion of central venous catheters using angiographic techniques in hemodialysis patients with previous multiple catheterizations is a safe and effective procedure with few complications and high success rates.

  12. Radiation exposure of patients from paediatric cardiac catheterizations. Part 2. Results of patient related measurements

    International Nuclear Information System (INIS)

    Age, entire exposure duration and dose-area products for pa and lat beam as well as the number of angiographies have been recorded for 2114 pediatric cardiac catheterizations within the time period 1982 to 1996. Furthermore, the average field dimensions and sizes at the patient entrance surface for pa and lat beams and the frequency distributions for dose-area product rates, the entire dose-area products and the effective doses, calculated by means of age class dependent conversion factors, are given for all patients. The effective doses for new-borns are higher by about a factor 2 (Q50=6.5 mSv compared to 3.0 mSv) compared to children of higher age class, despite of the quite smaller body dimensions and thus smaller dose-area product rates. Cancer risks by radiation exposure are significantly higher for new-borns than for elder children for the same effective dose. Although no age specific factor can be given it is possible to derive from literature data, that cardiac catheterizations cause radiation risks, which are larger at least by a factor 2 to 4 with decreasing age, especially for thyroid and breast cancer (the latter more for girls).

  13. Echocardiography to magnetic resonance image registration for use in image-guided cardiac catheterization procedures

    International Nuclear Information System (INIS)

    We present a robust method to register three-dimensional echocardiography (echo) images to magnetic resonance images (MRI) based on anatomical features, which is designed to be used in the registration pipeline for overlaying MRI-derived roadmaps onto two-dimensional live x-ray images during cardiac catheterization procedures. The features used in image registration are the endocardial surface of the left ventricle and the centre line of the descending aorta. The MR-derived left ventricle surface is generated using a fully automated algorithm, and the echo-derived left ventricle surface is produced using a semi-automatic segmentation method provided by the QLab software (Philips Healthcare) that it is routinely used in clinical practice. We test our method on data from six volunteers and four patients. We validated registration accuracy using two methods: the first calculated a root mean square distance error using expert identified anatomical landmarks, and the second method used catheters as landmarks in two clinical electrophysiology procedures. Results show a mean error of 4.1 mm, which is acceptable for our clinical application, and no failed registrations were observed. In addition, our algorithm works on clinical data, is fast and only requires a small amount of manual input, and so it is applicable for use during cardiac catheterization procedures.

  14. Diagnosis of total anomalous pulmonary venous return (TAPVR): Plain films, echographic, and cardiac catheterization correlation

    International Nuclear Information System (INIS)

    The ''typical'' radiographic features in infants with total anomalous pulmonary venous return (TAPVR) may not be apparent and this rare anomaly may be missed. The plain films of 30 patients with TAPVR confirmed at autopsy or on cardiac catheterization were retrospectively reviewed. There were 17 patients with supracardiac anomalous return, six with coronary sinus or right atrial return, seven with infradiaphragmatic return, and three patients with mixed types. Obstruction was noted in seven patients with supracardiac anomalous return and seven with infracardiac return. In five of 14 cases of obstruction, the chest radiograph did not suggest obstruction; on cardiac catheterization these patients all had evidence of increased pulmonary vascular resistance (PVR). Pulmonary venous obstruction, even when severe, may be masked by increased PVR, which may lead to decreased pulmonary arterial flow and enhanced right-to-left shunting through a patent ductus arteriosus or at the atrial level. An elevated PVR, particularly in the neonate, may help explain the variability of plain film findings in patients with TAPVR

  15. Factors affecting the radiation dose to the lens of the eye during cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Concern has been expressed about relatively high radiation doses to the lens of the eye received by the operator during cardiac catheterization studies. A study was undertaken to assess occupational doses received by cardiologists and to examine the factors that affect the individual's eye dose. Eighteen cardiologists working in five catheterization laboratories at three centres were included in the study. Their eye doses, workload and individual study details were monitored at each centre. Operating dose rates and scattered radiation were also measured for each unit to compare equipment performance. The study demonstrated that the relationships between the cardiologist's eye dose and factors such as the dose efficiency of the X-ray equipment, scattered dose rates, examination protocols and workload are complex and vary from centre to centre. Because of these variations general workload limits may be inaccurate and should only be used for general guidance when no direct measurements are available. Such limits should be verified by local measurements as soon as is practical. (Author)

  16. Effect of pulsed progressive fluoroscopy on reduction of radiation dose in the cardiac catheterization laboratory

    International Nuclear Information System (INIS)

    The increased application of therapeutic interventional cardiology procedures is associated with increased radiation exposure to physicians, patients and technical personnel. New advances in imaging techniques have the potential for reducing radiation exposure. A progressive scanning video system with a standard vascular phantom has been shown to decrease entrance radiation exposure. The effect of this system on reducing actual radiation exposure to physicians and technicians was assessed from 1984 through 1987. During this time, progressive fluoroscopy was added sequentially to all four adult catheterization laboratories; no changes in shielding procedures were made. During this time, the case load per physician increased by 63% and the number of percutaneous transluminal coronary angioplasty procedures (a high radiation procedure) increased by 244%. Despite these increases in both case load and higher radiation procedures, the average radiation exposure per physician declined by 37%. During the same time, the radiation exposure for technicians decreased by 35%. Pulsed progressive fluoroscopy is effective for reducing radiation exposure to catheterization laboratory physicians and technical staff

  17. Intra-tumorous embolization therapy through micro-catheterization for small carcinoma of the liver

    International Nuclear Information System (INIS)

    Objective: To study the value of the intra-tumorous embolization therapy using the skills of micro-catheterization for small carcinoma of the liver. Methods: 83 cases of embolization therapy through micro-catheter were performed in 26 patients who had single nodular hepatocellular carcinoma (23 patients) or liver metastasis (3 patients). 80 cases of the intra-tumorous embolization therapy using hot lipiodol (100 degree C) were performed in 26 patients. The protective embolization with micro-coil were done in 2 patients. One cases of the fistula embolization using absolute alcohol was done in one patient with small intra-tumorous A-V fistula. Results: The completely filled-full intra--tumorous embolization was obtained in all patients, although the negative finding on angiogram of celiac and superior mesenteric arteries occurred in 3 patients. The complete necrosis was confirmed in 2 patients followed by carcinoma resection. Within the follow-up 14 months to 55 months (average 35 months), 26 patients were all alive and there was no serious complication occurred. Conclusions: The completely filled-full intra-tumorous embolization for small carcinoma of the liver can be achieved by using the skills of micro-catheterization therapy. The satisfactory preliminary results seem to be comparable to that of the surgery. There is need for further study

    We simulated needle paths based on the central landmark used for central venous catheterization of the internal jugular vein. We obtained ultrasound images to quantify the landmark's accuracy (precision and bias) in 107 subjects placed in Trendelenburg position with their heads turned 30-35 degrees. We also determined the frequency of simulated carotid artery puncture. The simulated needle path missed the middle 80% of the lumen of the internal jugular vein in 34% of subjects (95% confidence interval [CI], 25% to 44%) and traversed the carotid artery in 26% of subjects (95% CI, 18% to 35%). Both events occurred in 20% of subjects (95% CI, 13%-29%). The landmark had a medial bias of 3.7 mm (95% CI, 2.7 to 4.8); it was more often (77 of 104 subjects) medial to the center of the right internal jugular vein (P yield frequent success on first needle pass without risk of carotid puncture because of its imprecision and bias. The measured bias should be considered when the central landmark is used for central venous catheterization. PMID:16632804

    2012-03-01

    Full Text Available Abstract Background A vaginal fistula is a devastating condition, affecting an estimated 2 million girls and women across Africa and Asia. There are numerous challenges associated with providing fistula repair services in developing countries, including limited availability of operating rooms, equipment, surgeons with specialized skills, and funding from local or international donors to support surgeries and subsequent post-operative care. Finding ways of providing services in a more efficient and cost-effective manner, without compromising surgical outcomes and the overall health of the patient, is paramount. Shortening the duration of urethral catheterization following fistula repair surgery would increase treatment capacity, lower costs of services, and potentially lower risk of healthcare-associated infections among fistula patients. There is a lack of empirical evidence supporting any particular length of time for urethral catheterization following fistula repair surgery. This study will examine whether short-term (7 day urethral catheterization is not worse by more than a minimal relevant difference to longer-term (14 day urethral catheterization in terms of incidence of fistula repair breakdown among women with simple fistula presenting at study sites for fistula repair service. Methods/Design This study is a facility-based, multicenter, non-inferiority randomized controlled trial (RCT comparing the new proposed short-term (7 day urethral catheterization to longer-term (14 day urethral catheterization in terms of predicting fistula repair breakdown. The primary outcome is fistula repair breakdown up to three months following fistula repair surgery as assessed by a urinary dye test. Secondary outcomes will include repair breakdown one week following catheter removal, intermittent catheterization due to urinary retention and the occurrence of septic or febrile episodes, prolonged hospitalization for medical reasons, catheter blockage, and

    Full Text Available Plasma soluble CD40 ligand (sCD40L is mainly generated by cleavage of CD40L from the surface of activated platelets, and therefore considered a platelet activation marker. Although the predictive value of sCD40L for ischemic events has been demonstrated in patients with acute coronary syndromes (ACS, studies on the association of sCD40L with cardiovascular outcomes in lower risk populations yielded heterogeneous results. We therefore sought to investigate factors influencing sCD40L levels, and the predictive value of sCD40L for long-term ischemic events in unselected, aspirin-treated patients undergoing cardiac catheterization. sCD40L was determined by a commercially available enzyme-linked immunosorbent assay in 682 consecutive patients undergoing cardiac catheterization. Two-year follow-up data were obtained from 562 patients. Dual antiplatelet therapy with aspirin and clopidogrel was associated with significantly lower levels of sCD40L and lower platelet surface expressions of P-selectin and activated GPIIb/IIIa compared to aspirin monotherapy (all p≤0.01. Hypertension was linked to lower plasma concentrations of sCD40L, whereas female sex, increasing high-sensitivity C-reactive protein, and hematocrit were associated with higher sCD40L concentrations (all p<0.05. sCD40L levels were similar in patients without and with the primary endpoint in the overall study population (p = 0.4. Likewise, sCD40L levels did not differ significantly between patients without and with the secondary endpoints (both p≥0.4. Similar results were obtained when only patients with angiographically-proven coronary artery disease (n = 459, stent implantation (n = 205 or ACS (n = 125 were analyzed. The adjustment for differences in patient characteristics by multivariate regression analyses did not change the results. ROC curve analyses did not reveal cut-off values for sCD40L for the prediction of the primary or secondary endpoints. In conclusion, plasma sCD40L

  1. A preliminary discussion of angiographic anatomy and variations of rabbit hepatic vessels and catheterization methods of hepatic artery

    International Nuclear Information System (INIS)

    Objective: To study the normal angiographic anatomy and variations of rabbit hepatic vessels, and explore the optimal method for hepatic artery catheterization. Methods: 30 rabbits were divided into two groups randomly. Modified surgical method and interventional method were used to catheterize hepatic artery respectively, and followed by angiography to demonstrate the normal anatomy and variations of rabbit celiac artery, hepatic artery and portal vein. Results: The route and distribution of rabbit celiac artery and hepatic artery were very different from human's. The commonly seen variation showed the differences in branching bifurcation of hepatic-gastric artery, with the incidence of 13.3%. The rates of successfully hepatic artery catheterization with surgical and interventional methods were 86.6%(13/15) and 80%(12/15) respectively (P>0.05). The surgical method will not be successful, whenever there's variation. Conclusion: The normal anatomy and variation of rabbit celiac artery and hepatic artery are quite different from human's. Both surgical and interventional catheterizations could be rather successful but possessing advantages and disadvantages of each its own. (authors)

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of superselective catheterization by using microcatheter in interventional chemoembolization for multiple hepatocarcinomas. Methods: A total of 68 patients with multiple hepatocarcinomas were enrolled in this study. The clinical data were retrospectively analyzed. Superselective catheterization by using a microcatheter was carried out in 34 cases (study group) and superselective catheterization by using a 4-5 F common catheter was performed in 34 cases (control group). The hepatic dysfunctions and the survival rate at 0.5, 1, 2 years were compared between the two groups. Results: The liver function of the patients in study group was much better than that of the patients in control group (P<0.05), and the survival time of the patients in study group was much longer than that of the patients in control group (P<0.05). Conclusion: For the treatment of multiple hepatocarcinomas, interventional chemoembolization by using microcatheter superselective catheterization technique is technically simple and clinically effective with high success rate and fewer complications.

    International Nuclear Information System (INIS)

    Objective: To evaluate the practicability and safety of the percutaneous transbrachial approach (TBA) for diagnostic coronary angiography and therapeutic percutaneous coronary interventions. Study Design: Quasi experimental study. Place and Duration of Study: The study was carried out in Armed Forces Institute of Cardiology- National Institute of Heart Diseases (AFIC-NIHD) from March 2009 to May 2011. Patients and Methods: We collected data of 100 consecutive patients who underwent coronary catheterization by the percutaneous transbrachial approach. Transbrachial catheterization was performed only if the radial access failed or radial pulse was feeble. Study endpoints included successful brachial artery catheterization, vascular and neurological complications at access site and procedure success rate. Results: Mean age of the patients was 54 years (range 33-79 yrs) and 65(65%) were males and 35 (35%) were females. The right brachial artery was used in all of the cases. Procedural success was achieved in 100% of the patients. Coronary angiography was performed in 70 patients and percutaneous coronary interventions were done in 30 cases. Out of these 30 cases, PCI to left coronary arteries (LAD and LCX) were performed in 19 patients while 11 patients had PCI to right coronary artery (RCA). No case of vascular complications such as major access site bleeding, vascular perforation, brachial artery occlusion causing forearm ischemia, compartment syndrome, vascular spasm or failure to catheterize coronary arteries requiring alternate vascular access were observed. Conclusion: Brachial artery is a safe and easily accessible approach for coronary angiography and percutaneous coronary interventions. (author)

    Full Text Available Introduction: Central venous catheterization (CVC can be an important component of the management of patients with severe sepsis and septic shock. CVC, however, is a time- and resource-intensive procedure associated with serious complications. The effects of the absence of shock or the presence of relative contraindications on undertaking central line placement in septic emergency department (ED patients eligible for early goal-directed therapy (EGDT have not been well described. We sought to determine the association of relative normotension (sustained systolic blood pressure >90 mmHg independent of or in response to an initial crystalloid resuscitation of 20 mL/kg, obesity (body mass index [BMI] ≥30, moderate thrombocytopenia (platelet count <50,000 per μL, and coagulopathy (international normalized ratio ≥2.0 with unattempted CVC in EGDT-eligible patients. Methods: This was a retrospective cohort study of 421 adults who met EGDT criteria in 5 community EDs over a period of 13 months. We compared patients with attempted thoracic (internal jugular or subclavian CVC with those who did not undergo an attempted thoracic line. We also compared patients with any attempted CVC (either thoracic or femoral with those who did not undergo any attempted central line. We used multivariate logistic regression analysis to calculate adjusted odd ratios (AORs. Results: In our study, 364 (86.5% patients underwent attempted thoracic CVC and 57 (13.5% did not. Relative normotension was significantly associated with unattempted thoracic CVC (AOR 2.6 95% confidence interval [CI], 1.6-4.3, as were moderate thrombocytopenia (AOR 3.9; 95% CI, 1.5-10.1 and coagulopathy (AOR 2.7; 95% CI, 1.3-5.6.

    The pulsatile flow of blood in a catheterized blood vessel is analyzed. The flow of blood in vessel is modeled as the flow of two immiscible fluids. The fluid in the core region is characterized as a non-Newtonian viscoelastic fluid satisfying the constitutive equation of an Oldroyd-B fluid. The fluid in the peripheral region is treated as a Newtonian fluid. The catheter inside the vessel is modeled as a rigid tube of very small radius. The resulting differential system for velocity in each region is computed numerically by finite-difference scheme and analytically by Laplace transform. A comparison of numerical solution with Laplace transform solution is carried out. Various physical quantities of interest through the computed velocity are also analyzed. PMID:27548476

    BACKGROUND: Pig islet xenotransplantation has the potential to overcome the shortage of donated human islets for islet cell transplantation in type 1 diabetes. Testing in non-human primate models is necessary before clinical application in humans. Intraportal islet transplantation in monkeys is usually performed by surgical infusion during laparotomy or laparoscopy. In this paper, we describe a new method of percutaneous transhepatic portal catheterization (PTPC) as an alternative to current methods of islet transplantation in rhesus monkeys. METHODS: We performed ultrasound-guided PTPC in five adult rhesus monkeys weighing 7-8 kg, with portal vein catheterization confirmed by digital subtraction angiography. We monitored for complications in the thoracic and abdominal cavity. To evaluate the safety of ultrasound-guided PTPC, we recorded the changes in portal pressure throughout the microbead transplantation procedure. RESULTS:  Ultrasound-guided PTPC and infusion of 16 000 microbeads/kg body weight into the portal vein was successful in all five monkeys. Differences in the hepatobiliary anatomy of rhesus monkeys compared to humans led to a higher initial complication rate. The first monkey died of abdominal hemorrhage 10 hours post-transplantation. The second suffered from a mild pneumothorax but recovered fully after taking only conservative measures. After gaining experience with the first two monkeys, we decreased both the hepatic puncture time and the number of puncture attempts required, with the remaining three monkeys experiencing no complications. Portal pressures initially increased proportional to the number of transplanted microbeads but returned to pre-infusion levels at 30 minutes post-transplantation. The changes in portal pressures occurring during the procedure were not significantly different. CONCLUSIONS: Ultrasound-guided PTPC is an effective, convenient, and minimally invasive method suitable for use in non-human primate models of

  14. Fluoroscopy time during cardiac catheterization procedures using the radial and femoral routes

    International Nuclear Information System (INIS)

    Background: Use of trans-radial route for cardiac catheterization is on the rise but is associated with increased radiation exposure to the operator. Our aim was to compare the radiation exposure, by taking fluoroscopy time (FT) as a surrogate of radiation exposure, to the operator with femoral and radial routes. Methods: This prospective observational study was carried out at Army Cardiac Center Lahore from lst Jan to 1st June 2013. Mean fluoroscopy times via trans-radia (TR) and trans-femoral (TF) routes were compared. Procedure time was considered as time from sheath insertion to the finish of the diagnostic and interventional procedure. Descriptive statistics were used to explain the data. Chi square test was applied to compare qualitative variables between them. Results: A total of 1,110 diagnostic and PCI cases were performed out of which there were 850 diagnostic CA and 260 PCI cases. The mean procedure time and mean fluoroscopy time for TF-CA was 15.5 ± 5.5 minutes and 4.3 ± 3.2 minutes respectively in the current study while for TR-CA was 6.6 ± 4.1. For TF-PCI, mean procedure time was 42.3 ± 16.7 minutes, mean fluoroscopy time was 11.6 ± 7.7 minutes and for TR-PCI it was 55.3 ± 19.2 and 15.4 ± 12.1. Conclusion: Radial route for cardiac catheterization procedures is associated with longer fluoroscopy time leading to increased radiation exposure to the operator along with an increased use of contrast.

  16. A New Technique for Superselective Catheterization of Arteries: Preshaping of a Micro-Guide Wire into a Shepherd's Hook Form

    International Nuclear Information System (INIS)

    We wanted to introduce a new technique for superselective catheterization of arteries with preshaping of a micro-guide wire into a shepherd's hook form, and this is useful for superselection of small arteries branching at an acute angle from a large parent artery for the treatment of tumors and hemorrhages. We developed a superselective catheterization technique by using preshaping of a micro-guide wire into a shepherd's hook form. We encountered six patients in our practice for whom we failed to catheterize the small tumor-feeding arteries that branched at an acute angle from wide parent arteries during chemoembolization of hepatocellular carcinoma; the parent arteries were the right inferior phrenic artery (n = 4) and the left gastric artery (n = 1) from the celiac axis with celiac stenosis due to compression by the median arcuate ligament and the proper hepatic artery from the gastroduodenal artery (n = 1) in a patient who had celiac axis occlusion with collateral circulation via the pancreaticoduodenal arcade from the superior mesenteric artery. In these consecutive six patients, we tested the usefulness of this new technique with employing preshaping of a micro-guide wire into a shepherd's hook form for superselective catheterization of targeted vessels. The target arteries were successfully catheterized and satisfactory transcatheter arterial chemoembolization was performed in all six patients. There were no significant complications such as arterial dissection. We developed a technique that is effective for superselection of vessels with preshaping of micro-guide wire into a shepherd's hook hook form, and we successfully applied it during chemoembolization of hepatocellular carcinoma. This technique can be useful for superselection of small arteries that branch from a large parent artery at acute angles for the treatment of tumors and hemorrhages

    Full Text Available Background: Although some investigations have shown higher rates of successful first attempt and fewer attempts by using ultrasound-guided Internal Jugular Vein (IJV catheterization, arterial puncture is still common.. Objectives: The present study aimed to investigate US-guided catheterization of the right IJV via medial-oblique technique and also compare this technique to short-axis technique in open-heart surgery patients.. Patients and Methods: In this randomized clinical trial, 80 patients referred to cardiac operating room of Namazi hospital, Shiraz, Iran from March to July 2014 were selected using census method. Block randomization with website was also done. Then, the patients were divided into two groups of 40, Short Axis Group (SAG and Medial-Oblique Group (M-OG. For short-axis technique, patient’s head was positioned at zero degree angulation with his trunk. For medial-oblique technique, on the other hand, patient’s head was tilted to left to 45 degrees between the head and trunk. Sex, age, Body Mass Index (BMI, access time, guidewire time, cannulation time, total attempts for catheterization, first, second, and third attempt success, arterial puncture, hematoma, bleeding, and catheter malposition were recorded. The overlap between the carotid artery and IJV in zero- and 45-degree angulation was estimated through ultrasound print. After all, Kolmogorov-Smirnov test was used to assess normal distribution of the data. Then, the data were analyzed through Student’s t-test, Mann-Whitney U test, and chi-square test. P < 0.05 was considered as statistically significant.. Results: The results showed no significant differences between the two groups regarding the duration of different catheterization steps (P = 0.376. In all the cases in both groups, accessing the vein was successful with three attempts or less. There were no clinical complications of catheterization in the two groups. The mean of overlap was 23.60 ± 33.47 in zero

  19. Evaluation of radiation doses and dose conversion coefficients for pediatric cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Pediatric cardiac catheterization covers both diagnostic and therapeutic procedures that range from simple to complex and can subject pediatric patients to varying radiation doses. There is limited information on radiation doses delivered by pediatric cardiac catheterization procedures and there is no recommended reference dose levels established yet. The study aims to determine the variation in patient radiation doses in terms of dose area product values and effective doses; determine factors that contribute to high doses to optimize protection; and determine the effective dose conversion coefficient. It is also aimed to provide data to help in the establishment of reference dose levels. A total of 761 pediatric patients belonging to age groups 0, 1, 5 and 10 years who undergo diagnostic and three selected therapeutic procedures at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia are included in the study. Therapeutic procedures include COA, PDA and pulmonary procedures. Fluoroscopy and cine radiography are used in all procedures. Patient demography (weight, age, gender and height), radiographic technique factors, fluoroscopy and cine time, frame rate, and dose area product values are taken from patients records. Results show that the kVp varies by ± 1 kVp between procedures and by ± 6 kVp between AP and oblique + lateral projection for all procedures. The mA for lateral and oblique is about 40-70% higher than for AP. Effective doses for each procedure are estimated from the DAP values. The mean DAP and effective dose per procedure are analyzed for correlation with patient equivalent cylindrical diameter, weight, fluoroscopy time and number of frames. Initial results show that age group 0 and 1 year old have the highest mean value for effective dose (11.3 and 13.8 mSv respectively) for pulmonary procedure. Pooling all ages for each procedure, the pulmonary and PDA procedures gave the highest mean values for effective dose (10 and 8.2 m

    Cardiac catheterization is important in the diagnosis and risk stratification of pulmonary hypertensive vascular disease (PHVD) in children. Acute vasoreactivity testing provides key information about management, prognosis, therapeutic strategies, and efficacy. Data obtained at cardiac catheterization continue to play an important role in determining the surgical options for children with congenital heart disease and clinical evidence of increased pulmonary vascular resistance. The Pediatric and Congenital Heart Disease Task Forces of the Pulmonary Vascular Research Institute met to develop a consensus statement regarding indications for, conduct of, acute vasoreactivity testing with, and pitfalls and risks of cardiac catheterization in children with PHVD. This document contains the essentials of those discussions to provide a rationale for the hemodynamic assessment by cardiac catheterization of children with PHVD. PMID:27076908

  1. DIAGNOSTIC CARDIAC CATHETERIZATION USING THE MEDRAD AVANTA FLUID MANAGEMENT SYSTEM AS COMPARED TO THE TRADITIONAL MANUAL INJECTION METHOD

    Energy Technology Data Exchange (ETDEWEB)

    Winniford, Michael D

    2013-02-08

    Nearly 4 million patient procedures performed annually in US cardiac catheterization laboratories utilize contrast media to achieve vessel opacification. The amount of contrast media used is variable and depends on the complexity of the procedure, the method of contrast delivery as well as the skill-level of the operator. Since the total amount of contrast used for each procedure can have both patient safety and economic implications, it is essential for cardiologists to have the ability to control contrast delivery such that optimal angiographic image quality is achieved using the least amount of contrast. Although the complication rate associated with cardiac catheterization remains low, the most common serious complication, contrast-induced nephropathy (CIN), is associated with poor prognosis and a high mortality rate. Numerous interventional strategies for preventing and reducing the severity of CIN have demonstrated varying degrees of clinical benefit, but none has been shown to reliably prevent this serious complication. To date, the most effective approach for reducing the risk of CIN is to properly hydrate the patient and to minimize the amount of contrast media administered. Automated injection systems are intended for use in virtually all cardiac catheterization procedures and have numerous features which can provide potential advantages over traditional methods. With automated injection technology the operator is able to control and precisely monitor contrast delivery. Additionally, the MEDRAD Avanta Fluid Management Injection System utilizes a sterile contrast reservoir which eliminates the need to discard unused contrast in individual opened containers following each procedure. Considering that an average of 50% of opened contrast media is wasted using manual injection methods, this savings can provide a substantial economic benefit. Automated systems also facilitate the use of smaller (5 French) catheter sizes. Precise flow control and the use of

    OBJECTIVE Anesthetic management for interventional cardiac procedures/cardiac catheterization in pediatric patients is challenging. Cardiac anomalies vary from simple to complex congenital cardiac anomalies, shunts may be present at multiple levels and patients may be profoundly cyanotic, may be with ventricular dysfunction. They usually require sedation and analgesia to maintain steady stable state. In adults, such type of procedures can be well managed with local anesthesia....

  8. Percutaneous transsplenic portal catheterization combined with TIPS for the treatment of portal vein thrombosis associated with cavernous transformation

    International Nuclear Information System (INIS)

    Objective: To evaluate the feasibility, safety and efficacy of percutaneous transsplenic portal catheterization combined with transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of portal vein thrombosis (PVT) associated with cavernous transformation. Methods: Percutaneous transsplenic portal catheterization was performed in 3 patients suffered from PVT with cavernous transformation in order to reopen the portal vein, then, TIPS was carried out to establish the portal shunt. A follow-up of 22-40 months period was conducted to observe therapeutic results, stent patency, hepatic function and complications. Results: The procedure was successfully completed in all three patients. One patient developed early symptoms of hepatic encephalopathy two times during the following 7 months, and the symptoms disappeared after medication was employed. In one patient the bilirubin was persistently increased in 6 months after the treatment, and there was no significant difference in the bilirubin level compared to that before the procedure. The remaining patient showed good recovery after the procedure. No complications occurred during the interventional management, and in a follow-up period of 22-40 months the shunt remained patency and no bleeding reoccurred. Conclusion: In treating the portal vein thrombosis associated with cavernous transformation, the choices of therapeutic methods are limited. Thus, as a safe and effective technique, percutaneous transsplenic portal catheterization combined with transjugular intrahepatic portosystemic shunt may be used clinically, although the procedure carries difficulties as well as challenges.

  9. Retrograde catheterization via politeal artery for the treatment of ipsilateral superficial femoral artery occlusive disease: its clinical application

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical effect and application of retrograde catheterization via politeal artery in treating ipsilateral superficial femoral artery occlusive diseases. Methods: During the period from Jan. 2008 to June 2011, 15 patients with superficial femoral artery occlusive diseases were collected. A total of 17 narrowed or obstructed superficial femoral arteries were detected, including right (n=10) and left (n=7) femoral arteries. The length of the diseased artery ranged from 9 to 18 cm, with a mean of (12.5±6.8) cm. Percutaneous angioplasty (PTA) through ipsilateral retrograde catheterization via politeal artery together with stent implantation was performed to reopen the narrowed or obstructed superficial femoral arteries. After the procedure all patients were followed up for 3-24 months. The clinical results were analyzed. Results: The therapeutic success rate was 100% (17/17). No serious complications occurred. After the treatment, the ischemic symptoms were markedly improved or even disappeared. In 89.47% of patients (17/19) the superficial femoral arteries remained patent during the follow-up period. The preoperative ankle brachial index (ABI) was 0.15-0.48 (mean 0.28), while the postoperative ABI was 0.69-1.05 (mean 0.88). The difference in ABI between pre-operation and post-operation was statistically significant (P<0.05). Conclusion: For the treatment of superficial femoral arterial occlusive diseases, PTA through ipsilateral retrograde catheterization via politeal artery together with stent implantation is a safe effective therapy.

    Full Text Available Abstract The severity index is a new echocardiographic measure that is thought to be an accurate indicator of aortic leaflet pathology in patients with AS. However, it has not been validated against cardiac catheterization or Doppler echocardiographic measures of AS severity nor has it been applied to patients with aortic sclerosis. The purposes of this study were to compare the severity index to invasive hemodynamics and Doppler echocardiography across the spectrum of calcific aortic valve disease, including aortic sclerosis and AS. 48 patients with aortic sclerosis and AS undergoing echocardiography and cardiac catheterization comprised the study population. The aortic valve leaflets were assessed for mobility (scale 1 to 6 and calcification (scale 1 to 4 and the severity index was calculated as the sum of the mobility and calcification scores according to the methods of Bahler et al. The severity index increased with increasing severity of aortic valve disease; the severity indices for patients with aortic sclerosis, mild to moderate AS and severe AS were 3.38 ± 1.06, 6.45 ± 2.16 and 8.38 ± 1.41, respectively. The aortic jet velocity by echocardiography and the square root of the maximum aortic valve gradient by cardiac catheterization correlated well with the severity index (r = 0.84, p

    Full Text Available Cardiac catheterization laboratories are experiencing phenomenal change, as their volume increases and cases become more complex. In the search for the perfect angiographic result, interventional cardiologists have explored numerous therapeutic complementary devices that are used in the cath labs to facilitate achieving this elusive prize. Unfortunately, these adjunctive interventional devices are lacking in the majority of cath labs all around developing countries including those in Middle East /North Africa region (MENA region. In fact, most of coronary interventions here became restricted to implantation of bare metal stents or drug-eluted stents with or without simple balloon predilatation or post-dilatation. The limited adoption of complementary devices reflects concerns of the high costs for these devices, un-suitability for their re-sterilization, having their own learning curve with compelling continuous need for high level of training.In this review, we will summarize the evidence base concerning most of the important therapeutic complementary cardio-vascular interventional devices and comment on challenges facing the more widespread adoption of their use in MENA region .Hopefully, this objective analysis would help fostering their further growth and penetration into the markets, making them part of daily practice

  12. Risk factors for acute urinary retention requiring temporary intermittent catheterization after prostate brachytherapy: a prospective study

    International Nuclear Information System (INIS)

    Purpose: We prospectively investigated prognostic factors for men undergoing transperineal radioactive seed implantation for prostate cancer at the University of Washington. Methods and Materials: Between February and April, 1998, 62 consecutive unselected patients were prospectively followed after brachytherapy for early-stage prostate adenocarcinoma. Pretreatment variables included age, American Urological Association (AUA) score, uroflowimetry, and prostate volume by ultrasound. Nonrandomized variables included hormonal therapy, seed type, and use of pelvic radiotherapy. Patients were contacted by phone at one week postoperatively and at one-month intervals thereafter. Follow-up continued until all patients provided the date of last catheterization. Results: Urinary retention rate at one week was 34% (21 of 63 patients). At one month, 29%; at three months, 18%; and at six months, 10%. Preoperative flow rate and post-void residual did not predict for retention (p=.48 and p=.58). Use of alpha blockers, hormonal therapy, type of seed (103Pd or 1251), or external beam radiotherapy had no impact on risk of retention at any followup point. Preimplant volume and AUA score predicted for retention on univariate analysis, but on multivariate analysis only postimplant volume remained significant (p=.02) for predicting retention risk and duration. Conclusion: Patients with large prostate size (>36 g) and higher AUA score (>10) appear to be at greater risk of risk of retention as well as duration of retention as defined in our study. Further investigation will be needed to clarify the risk of urinary retention for men undergoing brachytherapy

  13. Usefulness of echography for venous catheterism in patients with periodic hemic dialysis

    International Nuclear Information System (INIS)

    Background.Complications associated with central venous catheterization procedures are frequent.The aim of this study is to analyze the outcomes of echography for venous procedures in patients on periodic haemodialysis.Methods. A hundred and twenty-two (122) procedures were performed in 101 patients on periodic haemodialysis.Punctures were performed in the internal jugular vein (IJV) previous echographis assessment of the puncture site.Many procedures ()4) were guided by ecography.Results: sixty-six patients had normal IJV and 3 had both veins with thrombus.Thrombotic or small right IJV was seen in 27,7% patients while thrombotic, small or absent left IJV in 10%.Puncture procedures succeeded in 119 jugular veins.In 74,8% cases a guided puncture by echography was performed at the first attempt, while 4,2% at the second or third attempt.Punctures were performed after identifying IJV by echography in 21,0%.One complication related to punctures occurred the carotid artery was punctured in one case (0,8%).Conclusions: Abnormalities in IJV were frequent in the studied group of patients.Both preceded or guided punctures were successful, and minimized complications

    International Nuclear Information System (INIS)

    Objective: It's evaluation of fine needle puncture small guild wire insertion, followed by single step large tube catheterization in percutaneous transhepatic cholangic drainage. Methods: In total 37 cases of biliary tract obstruction were investigated, including 31 malignant and 6 benign. After PTC, a.018 guide wire was inserted to bile duct through the 22G chiba needle. The needle tract was dilated to exchange in a.035 guide wire which was then traced through the obstruction to duodenum. The needle tract was dilated and the obstruction was recanalized by a 8 mm balloon catheter. A 12F side holed drainage tube was then placed through the obstruction. Results: Technic success was obtained in 34 procedures, resulting in 28 inner and 6 extra drainage, in which 2 tubes were placed in 3 patients. Serious biliary hemorrhage occurred in 2 cases but was well control. A replacement was commended in 5 cases because of the migration or dislodgement of the drainage tubes. Conclusions: Fine needle puncture an small guild wire insertion avoid another liver puncture by cored needle, leading to a less invasive PTCD. Balloon dilation helps a fluent insertion of large drainage tube

  15. Increased chromosome damage in pediatric heart catheterization patients after diagnostic fluoroscopy and cineangiography

    International Nuclear Information System (INIS)

    Chromosome damage (CD) and sister chromatid exchange (SCE) levels were studied in lymphocytes from 30 pediatric heart catheterization patients receiving radiation during diagnostic fluoroscopy and cineangiography procedures. Forty-eight-hour CD and 72-hr SCE cultures were prepared from sequential samples taken from each patient: samples 1-3 via the catheter the same day (1) before exposure, (2) after fluoroscopy, and (3) after cineangiography; and sample 4 by venipuncture the next morning. Significant increases in CD (dicentrics, rings, and fragments), but not SCE, were observed. From a mean base level of 0.4% cells with CD, the CD levels increased 2-3-fold in samples 3 and 4 (p = .001). Rings only occurred in samples 3 and 4. While increased CD levels also correlated with increasing age, body surface area, and weight, partial correlations controlling for these factors clearly indicate that the CD effects are principally attributable to the radiological procedures (p = .001). Increased CD levels correlated with both the roentgen dose of cineangiography exposure (p = .002) and the volume of contrast medium (p = .000); however, partial correlations, controlling for either factor, indicate that the contrast medium was the principal factor (p = .006)

    Background Transradial approach catheterization is now widely used in coronary angiography and angioplasty.The ulnar artery,which is one of the two terminal branches of the brachial artery,may be a potential approach for cardiac catheterization.The aim of this study was to evaluate the safety and feasibility of a transulnar approach for coronary catheterization in non-selective patients.Methods A total of 535 consecutive patients were randomly assigned to transulnar approach (TUA) group (n=271) or transradial approach (TRA) group (n=264) upon arrival at the catheterization laboratory.Allen's test and inverse Allen's test were not routinely performed.Ultrasound-Doppler assessment of the forearm artery was performed before the procedure,two days after the procedure,and 30 days after the procedure.The primary endpoints of study were the rate of successful artery cannulation and the access-site related complications.The secondary endpoints included the number of needle punctures,total time for the procedure,and major adverse cardiac events (MACE).Results Successful puncture of the objective artery was obtained in 91.5% of the patients in the TUA group,and 95.1% of the patients in the TRA group (P >0.05).There was no significant difference in hematoma complications between the two groups (7.7% vs.4.2%,P=0.100).A motor abnormality of the hand was observed in one patient in the TUA group.There were no arteriovenous fistula or pseudoaneurysm observed in our study.Three (1.1%) patients in the TUA group and 8 (3.0%) patients in the TRA group had occlusion of the access artery (P=0.137),but none of the patients had symptoms or signs of hand ischemia.There were no significant differences in MACE between the two groups during follow-up.Conclusion The transulnar approach is an effective and safe technique for coronary catheterization in non-selective patients.

  17. Prognostic utility of the exercise thallium-201 test in ambulatory patients with chest pain: comparison with cardiac catheterization

    International Nuclear Information System (INIS)

    The goal of this study was to determine the prognostic utility of the exercise thallium-201 stress test in ambulatory patients with chest pain who were also referred for cardiac catheterization. Accordingly, 4 to 8 year (mean +/- 1SD, 4.6 +/- 2.6 years) follow-up data were obtained for all but one of 383 patients who underwent both exercise thallium-201 stress testing and cardiac catheterization from 1978 to 1981. Eighty-three patients had a revascularization procedure performed within 3 months of testing and were excluded from analysis. Of the remaining 299 patients, 210 had no events and 89 had events (41 deaths, nine nonfatal myocardial infarctions, and 39 revascularization procedures greater than or equal to 3 months after testing). When all clinical, exercise, thallium-201, and catheterization variables were analyzed by Cox regression analysis, the number of diseased vessels (when defined as greater than or equal to 50% luminal diameter narrowing) was the single most important predictor of future cardiac events (chi 2 = 38.1) followed by the number of segments demonstrating redistribution on delayed thallium-201 images (chi 2 = 16.3), except in the case of nonfatal myocardial infarction, for which redistribution was the most important predictor of future events. When coronary artery disease was defined as 70% or greater luminal diameter narrowing, the number of diseased vessels significantly (p less than .01) lost its power to predict events (chi 2 = 14.5). Other variables found to independently predict future events included change in heart rate from rest to exercise (chi 2 = 13.0), ST segment depression on exercise (chi 2 = 13.0), occurrence of ventricular arrhythmias on exercise (chi 2 = 5.9), and beta-blocker therapy (chi 2 = 4.3)

  18. Assessment of the x-ray dose to the patient in angiography and catheterization procedures in Israel

    International Nuclear Information System (INIS)

    Angiography and catheterization are medical procedures that involve high X-ray doses to the patient. This X-ray dose arises from the fluoroscopy, Cine and Digital Subtraction Angiography procedures used for interventional radiography. The main goal of the present work was to assess the average patient dose delivered by these procedures. For this purpose we carried out a survey m two major Israeli hospitals, using the integrated Dose Area Product meter which was part of the X-ray imaging equipment.We calibrated these Digital Subtraction Angiography instruments with our Digital Subtraction Angiography dosemeter.

    Occupational exposure to scattered radiation and protective equipment was assessed in 4 medical institutions in Kyushu, Japan. The areas where scattered radiation occurred, the scattered radiation dose in the operator's position, fluoroscopy time, the number of cinematography sessions, and annual number of patients were assessed, and the annual scattered radiation dose to the operator was estimated. Approximately 90% of scattered radiation was generated by the subject and the collimator. Measurement of scattered radiation during coronary arteriography yielded a dose of 255-1200 [{mu}Sv/hr.] during fluoroscopy and 3.8-26.7 [{mu}Sv/10 sec.] during radiography. The duration of fluoroscopy for ablation was much longer than during general examinations and PTCA, suggesting a possible contribution to occupational exposure. The data for the past 5 years show no marked change in total number of catheterizations, but the number of ablations has rapidly increased. Ablation requires specific skills, and thus it is frequently performed by only a few staff members, resulting in exposure being concentrated in a few specific persons. The estimated doses of scattered radiation to the eyes and thyroid gland, which are assumed to be the most highly exposed sites, were 116.2 [mSv/year] during fluoroscopy and 8.9 [mSv/year] during radiography, for a total of 125.1 [mSv/year]. This dose is very close to the maximum occupational exposure dose recommended by International Commission on Radiological Protection (ICRP), i.e., 150 [mSv/year]. A protective device that does not impose a burden on the operator or limit the functions of x-ray units was installed on top of the examining table as a measure to reduce the occupational dose. In an experiment using this device the scattered radiation dose during inguinal puncture decreased from 0.8 [mSv/hr.] to 0.02 [mSv/hr.], and the shielding rate was 2.5%. The dose was reduced 97.5%. The authors conclude that radiological personnel must make

    Considerable data indicates that patients NRMI-2) between June 1994 and April 1998 were identified. Patients were categorized into 4 age strata for purposes of analysis. A total of 61,232 cases met our inclusion criteria. Cardiac catheterization was performed during hospitalization in 78% of patients after an uncomplicated initial AMI. Age was inversely associated with receipt of cardiac catheterization: 85% of those or =70 years old. Regression analysis revealed that use of catheterization was 2.9 times greater (95% confidence intervals 2.7 to 3.2) in patients or =70 years old. Geographic location and payor status also strongly influenced utilization of this procedure. In conclusion, routine coronary angiography after uncomplicated AMI is extensively utilized in all age groups, particularly in those <50 years of age. The efficacy and cost effectiveness of this strategy in these patients has not yet been determined in clinical trials. PMID:11448404

  2. Entrance radiation doses during paediatric cardiac catheterizations performed for diagnosis or the treatment of congenital heart disease

    International Nuclear Information System (INIS)

    The purpose of this study was to estimate the radiation exposure of children, during cardiac catheterizations for the diagnosis or treatment of congenital heart disease. Radiation doses were estimated for 45 children aged from 1 d to 13 y old. Thermoluminescent dosemeters (TLDs) were used to estimate the posterior entrance dose (DP), the lateral entrance dose (DLAT), the thyroid dose and the gonads dose. A dose-area product (DAP) meter was also attached externally to the tube of the angiographic system and gave a direct value in mGy cm2 for each procedure. Posterior and lateral entrance dose values during cardiac catheterizations ranged from 1 to 197 mGy and from 1.1 to 250.3 mGy, respectively. Radiation exposure to the thyroid and the gonads ranged from 0.3 to 8.4 mGy to 0.1 and 0.7 mGy, respectively. Finally, the DAP meter values ranged between 360 and 33,200 mGy cm2. Radiation doses measured in this study are comparable with those reported to previous studies. Moreover, strong correlation was found between the DAP values and the entrance radiation dose measured with TLDs. (authors)

    In this paper, we proposed a novel master-slave robotic catheterization system with force feedback for VIS (Vascular Interventional Surgery). The force feedback to the operator on the master side is the key factor to improve the safety during VIS. The developed system used the MR (magneto rheological) fluid to realize force feedback, and it used the developed multidimensional monitoring interface to realize the visualization of force feedback, the developed multidimensional monitoring interface can monitor the motion information of the catheter and contact force between catheter tip or side wall and blood vessel wall, and the motion data of the catheter was collected and generated diagram for reference to surgeon. We have developed a force sensor array to detect the contact force between catheter tip or side wall and blood vessel wall. The force information was detected by the developed contact force sensor array when the catheter contacted with the blood vessel. The force feedback and multidimensional information monitoring interface evaluation experiments were done, the tracking characteristic evaluation experiments were also carried out, the experimental results indicated that the developed novel robotic catheterization system with force feedback and visualization of force feedback is effective for VIS, it can improve the safety during VIS.

    Full Text Available Background and Aims: Catheter-associated urinary tract infection (CAUTI is one of the most common health care acquired infection encountered in clinical practice. The present study was planned to assess the knowledge and attitude of health care providers regarding the indications for catheterization and methods of preventing CAUTI. Methods: A prospective questionnaire-based survey was done from March 2011 to August 2011. A structured questionnaire comprising of 41 items related to demographic details of the respondents, their knowledge regarding indications for catheterization and methods of preventing CAUTI was given to 54 doctors and 105 nurses. The response was evaluated for statistical correlation using a computer software. Results: The mean years of experience of the respondents in the health care setup was 6.8 years. Only 57% of the respondents could identify all the measures for prevention of CAUTI. The knowledge regarding the indication for catheterization though suboptimal was significantly better amongst the doctors as compared to nurses. Conclusion: The knowledge regarding indication and preventive measures was suboptimal in our study group. There is a tremendous scope of improvement in catheterization practices in our hospital and education induced intervention would be the most appropriate effort toward reducing the incidence of CAUTI.

Evidence of its routine practice in our low-resource setting is lacking, leading to increasing number of patients with a long-standing indwelling urinary catheter.Objective: To seek the opinion of patients already using indwelling catheters regarding the practice of self-catheterization.Patients and methods: Over a 4-month period, the opinion of every patient and patient’s relative that attended the regular urinary catheter clinic was sought using an intern-administered questionnaire. The data was analyzed using SPSS version 20.Results: A total of 108 patients completed the questionnaire. Age range was 16–100 years with a mean of 62.2±15.5 years. Only 30.5% of the patients had formal education beyond the primary level. The median cost for change of the indwelling catheter was 1,325 naira ($8.28 US with a range of 500–4,000 naira ($3.13–$25 USD. Analysis showed that: 70.8% of patients aged under 60 years/60.6% of those with formal education beyond primary level/61.9% of those wearing catheters for <3 months would give consent for training in self-catheterization. Higher cost of catheter change did not influence the decision to consider self-catheterization. Of the 59 patient relatives who completed the questionnaire, 63% of those younger than 50 years old and 69.2% of those with tertiary education would be willing to undertake training to administer self-catheterization.Conclusion: A select group of patients and accompanying relatives in our low-resource setting are willing to learn and practice self-catheterization.

    The unsteady flow characteristics of blood are analyzed through a catheterized stenotic artery with post-stenotic dilatation. A rigid tube with a pair of abnormal wall segments in close proximity to each other is employed to geometrically simulate the diseased artery. A micropolar fluid model is used to capture the rheological characteristics of the streaming blood in the annulus. The mild stenosis approximation is employed to derive the governing flow equation which is then solved using a robust finite difference method. Particular attention is paid to the effects of geometrical parameters of the arterial wall and rheological parameters of the blood on axial velocity, flow rate, resistance impedance and wall shear stress. The global behavior of blood is also analyzed through instantaneous pattern of streamlines. PMID:26541601

  10. The primary experimental study of self-made percutaneous catheterized thrombectomy device for acute massive pulmonary embolism

    International Nuclear Information System (INIS)

    Objective: To evaluate efficacy, feasibility and safety of the self-made percutaneous catheterized thrombectomy divice in animal model for thrombus removal. Methods: Seven dogs were selected, with acute massive pulmonary embolism animal models created by injecting thrombi into the pulmonary arterial trunk via percutaneous femoral vein approach. After half an hours the catheter sheath was inserted into the occluded pulmonary artery through right femoral vein in 5 dogs, left femoral vein in 1 dog and right internal jugular vein in another one. The procedure began to remove the thrombi with simultaneous recording the thrombectomy time and the blood volume drainage. Blood gass was tested before and after embolization together with those of thrombi removement, continuously monitored pulmonary arterial pressure and intermittently performed angiography. The mean time form vascular recanalization to euthanasia was 2 hours, and then the lung specimens were resected for histological examination. Results: One animal died of pulmonary arterial penetration during thrombi removal, but others were all alive by the end of the test. Mean time of removing thrombi was 2.4 minutes with mean volume blood drainage of 84 ml. Angiograms showed the approximately complete patency of the pulmonary arterial trunk after reopening of occlusion but still with remnont thrombi within distal branches and arterial pressure with blood gas returned to normal level. Pathology revealed the recanalization of pulmonary arterial trunk but with thromi still staying in the distal branches, and effusion around the arteries. Conclusions: The self-made percutaneous catheterized thrombectomy device is effective, feasible and comparatively safe in the treatment of acute massive pulmonary embolism in this primary test.

    Full Text Available Introduction: Nowadays, assessment of brain oxygen saturation, which is simply appliable and noninvasive method, can provide the anesthesia plans to be optimized according to the needs of the brain, which is the main target organ. Brain may be exposed to hypoxia due to supply-demand imbalance of oxygen not only in general anesthesia procedures but also in sedation practices. The aim of the study is to compare the effects of dexmedetomidine and propofol which are widely used agents for pediatric catheterization procedures on brain oxygen saturation using Fore-Sight. Material and Methods: A total of 44 patients undergoing diagnostic cardiac catheterization between 1 and 18 years old were included in the study. All patients, who were randomly divided into two groups, had ASA physical status I-II. In Group Propofol (Group P, n = 22,induction of sedation was made by midazolam (0.5 mg,iv + propofol (1m/kg,iv, and in Group Dexmedetomidine (Group D, n = 22, induction of sedation was made by midazolam (0.5 mg,iv +dexmedetomidine (1mcg/kg, iv. Throughout the sedation, cerebral tissue oxygen saturation (SctO 2 was recorded by Fore-Sight in addition to routine monitoring. Results: There were no statistically significant differences between the groups in terms of demographic data, hemodynamic data and sedation scores. On other hand, statistically significant decreases in cerebral tissue oxygen saturation were detected especially at 5th and 10th minutes, in Group D, while cerebral oxygenation level did not decrease in Group P. Though, statistically significant difference was determined between two groups in terms of cerebral oxygen saturation, the obtained data was not interpreted as cerebral desaturation. Conclusion: As a conclusion, there was a statistically significant but clinically insignificant decrease in cerebral tissue oxygen saturation in dexmedetomidine group compared to propofol group. Although it does not seem to be important in hemodynamic

  12. Transcatheter Thrombolysis with High-Dose Bolus Tissue Plasminogen Activator in Iatrogenic Arterial Occlusion after Femoral Arterial Catheterization

    International Nuclear Information System (INIS)

    Purpose: To assess the efficacy of percutaneous local thrombolysis with high-dose bolus recombinant tissue plasminogen activator (rt-PA) in patients with acute limb ischemia due to arterial thrombosis after cardiac catheterization.Methods: We treated eight patients (7 men; mean age 56 years) with thrombotic occlusion of both the common femoral artery (CFA) and external iliac artery (EIA) in six patients and of the CFA only in two patients. Two 5 mg boluses of rt-PA were injected into the proximal clot through a 5 Fr end-hole catheter and subsequently two additional boluses of 5 mg rt-PA were given through a catheter with multiple side-holes. In case of a significant amount of residual thrombus, a continuous infusion of 2.5 mg/hr of rt-PA was started.Results: Successful lysis was achieved in all patients. The mean duration of lysis was 2 hr 41 min. The mean total amount of rt-PA delivered was 23.16 mg. In four patients unmasked flow-limited dissections confined to the CFA were managed by prolonged balloon dilatation, while in the remaining four patients with extension of the dissection to the external iliac artery one or two Easy Wallstents were implanted. There was prompt relief of lower limb ischemic symptoms and signs in all patients. Two groin hematomas were conservatively treated.Clinical and color Doppler flow imaging follow-up with a mean duration of 15 months, showed no reappearance of ischemic symptoms or development of restenosis in any of the patients. One patient died 6 months after thrombolysis.Conclusions: Transcatheter thrombolysis with high-dose bolus rt-PA is a safe and effective treatment inpatients with iatrogenic arterial occlusion after femoral catheterization. Underlying dissections should be treated by prolonged balloon dilatation but stent implantation is often required

  13. Comparing study with two venous approaches of antegrade catheterization for thrombolysis in acute iliofemoral deep vein thrombosis

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical effectiveness of catheterization via the great saphenous vein for thrombolysis in acute iliofemoral deep vein thrombosis (IFVT). Methods: Patients with documented acute iliofemoral deep vein thrombosis were divided into two groups. Patients in group A received CDT with venous access through the ipsilateral great saphenous vein. The patients in group B received CDT via the ipsilateral popliteal vein. Clinical efficacy was evaluated by measuring the circumferences between the normal and affected limbs before and after treatment; the venous patency score, the rate of patency improvement based on venographic results; and the clinical results including the limbs edema reduction rate, the mean punctuation duration and complications; were all compared between the two groups. Results: The total effective rates between group A and group B showed no significant difference (95.2% vs 96%, P = 0.549); including the limbs edema reduction rates(86.6 ± 20.0% vs 85.7 ± 14.6%, P=0.868), likewise, the rates of venous patency improvement(57.9 ± 19.4% vs 57.7 ± 19.3%, P=0.968). The mean punctuation duration of group A was remarkable less than that of group B (7.3 minutes vs 16.7 minutes, P<0.05). The incidence of complications at the site of insertion in group A was lower than that in group B (P<0.05). Conclusions: The great saphenous vein is a new alternative access site for antegrade catheterization in catheter-directed thrombolysis for treatment of acute IFVT; more convenient and safe than popliteal venous approach.

    Objective To explore the influence of repeatedly PICC catheterized on catheter tip position. Methods We analyzed the catheter tip position of patients who located PICC in one level three class-A hospital in Beijing from May to October in 2014. A total of 381 effective medical records were collected and divided into having the history of catheterization group and having no history of catheterization group depending on patients whether catheterized before. The patients having the history catheterization were divided into ipsilateral catheter group(B1 group)and no ipsilateral catheter group(B0 group),the catheter tip position was compared. Results The best catheter tip position for patients having the history of catheterization was 30. 79% , which was lower than patients having no history group of 52. 66%(χ2 = 17. 565,P < 0. 01),and the patients of having catheterization history group had the incidence rate of shallow catheterization(47. 74% )higher than 35. 40% in the no catheterization history group(χ2 = 5. 817,P < 0. 05). The patients of having catheterization history group happened the incidence of catheter tip position acquired dystopia of venae subclavia higher than patients having no catheterization history group(P < 0. 05). The best catheter tip position had lower rate in the B1 group comparing with B0 group,but the patients acquired dystopia of venae subclavia in the B1 group was lower than the patients in the B0 group(P < 0. 05). Conclusions Multiple PICC catheterization reduces the accuracy of catheter tip position,and impacts the safety and reservation of PICC. We should minimize the non-planned extubation incidences. If patients require re-catheterizaiton,we should select the opposite limbs to catheterize without catheterizaiton contraindication to ensure the safe of PICC catheterization.%目的:探讨多次 PICC 置管对导管尖端位置的影响。方法对2014年5—10月北京市某三级甲等医院肿瘤科 PICC 置管患者的导管尖端

    Full Text Available Pulmonary arterial hypertension (PAH associated with systemic connective tissue diseases (SCTD is a poor prognostic manifestation of the latter that result in death if untreated. The invasive determination of hemodynamic parameters is prominent in diagnosing the disease and determining its treatment policy and prognosis.Objective: to analyze the results of catheterization in PAH-SCTD patients admitted to the V.A. Nasonova Research Institute of Rheumatology.Subjects and methods. The investigation included 59 patients admitted to the V.A. Nasonova Research Institute of Rheumatology from September 2009 to September 2014. PAH was diagnosed in accordance with the conventional guidelines. All the patients underwent right heart and pulmonary artery (PA catheterization at the diagnosis and over time during treatment.Results and discussion. All the patients included in the trial met the pre-capillary pulmonary hypertension (PH criteria: mean pulmonary artery pressure (MPAP ≥25 mm Hg; and PA wedge pressure (PAWP <15 mm Hg. The exclusion of other causes of PH (pulmonary fibrosis, left heart disease, and thromboembolism, as well as a high transpulmonary pressure gradient >15 mm Hg and pulmonary vascular resistance (PVR >3 Wood units could diagnose PAH in all our patients. There was a statistically highly significant association between pathological hemodynamic changes and functional class (FC. FC was found to be most closely correlated with right atrial pressure (RAP, cardiac output (CO, PVR, and cardiac index (CI. Among the most common manifestations of heart failure, only the presence of peripheral edemas was associated with worse hemodynamic parameters in PAH. It should be noted that out of two biomarkers (N-terminal pro-brain natriuretic peptide and uric acid, the former is largely related to the magnitude of changes in hemodynamic factors. The critical values of hemodynamic parameters were due to extreme edema – anasarca (RAP >17 mm Hg

    Accidental subclavian artery cannulation is an uncommon but potentially serious complication of central venous catheterization. Removal of a catheter inadvertently placed in the subclavian artery can lead to substantial bleeding, as achieving hemostasis in this area through manual compression presents considerable difficulty. Additionally, surgical treatment might be unsuitable for high-risk patients due to comorbidities. Here, we report a case of an inadvertently-inserted 11.5-French hemodialysis catheter in the subclavian artery during internal jugular venous catheterization. We performed percutaneous closure of the subclavian artery using three 6-French Perclose Proglide® devices with a balloon tamponade in the proximal part of the subclavian artery. Closure was completed without embolic neurological complications. PMID:27482271

  17. Radial Artery Coursing Behind the Biceps Brachii Tendon: Significance for the Transradial Catheterization and a Clinically Oriented Classification of the Radial Artery Variations

    International Nuclear Information System (INIS)

    In routine clinical practice the variations of the radial artery are the main reason for technical failure during transradial catheterization. If these variations are well documented, however, they do not represent a problem in the transradial approach. Therefore, we report here a rare case of the radial artery which is very strange but potentially valuable for the clinical practice: it arises at a right angle from the brachial artery and passes behind the biceps brachii tendon. Based on our findings and on an extensive literature review, we propose for the first time a clinically oriented classification of the variations of the radial artery. This classification is related to the catheterization success at the usual access site of the radial artery at the wrist.

    Paediatric cardiac catheterizations may result in the administration of substantial amounts of iodinated contrast media and ionizing radiation. The aim of this work was to investigate the effect of iodinated contrast media in combination with in vitro and in vivo X-ray radiation on lymphocyte DNA. Six concentrations of iodine (15, 17.5, 30, 35, 45, and 52.5 mg of iodine per mL blood) represented volumes of iodinated contrast media used in the clinical setting. Blood obtained from healthy volunteers was mixed with iodinated contrast media and exposed to radiation doses commonly used in paediatric cardiac catheterizations (0 mGy, 70 mGy, 140 mGy, 250 mGy and 450 mGy). Control samples contained no iodine. For in vivo experimentation, pre and post blood samples were collected from children undergoing cardiac catheterization, receiving iodine concentrations of up to 51 mg of iodine per mL blood and radiation doses of up to 400 mGy. Fluorescence microscopy was performed to assess γH2AX-foci induction, which corresponded to the number of DNA double-strand breaks. The presence of iodine in vitro resulted in significant increases of DNA double-strand breaks beyond that induced by radiation for ≥ 17.5 mg/mL iodine to blood. The in vivo effects of contrast media on children undergoing cardiac catheterization resulted in a 19% increase in DNA double-strand breaks in children receiving an average concentration of 19 mg/mL iodine to blood. A larger investigation is required to provide further information of the potential benefit of lowering the amount of iodinated contrast media received during X-ray radiation investigations.

  19. The establishment of implanted VX2 liver tumor model in rabbits and discussion on superselective left hepatic arterial catheterization with micro-catheter technique via femoral artery

    International Nuclear Information System (INIS)

    Objective: To establish the implanted VX2 liver tumor model in rabbits and to discuss the feasibility and technical features of superselective left hepatic arterial catheterization by using micro-catheter through the femoral artery catheter sheath. Methods: Forty New Zealand white rabbits were inoculated with fragments of VX2 tumor into the medial left lobe of liver by using a 16G lumbar puncture needle through laparotomy route. Two weeks later, all the rabbits were proved to be successfully inoculated with liver neoplasm on CT scanning. Then, the catheter sheath was inserted into one of the femoral arteries, which was followed by celiac artery angiography and left hepatic artery catheterization with a micro-catheter under DSA guidance in order to evaluate the main branches of celiac artery and the imaging manifestations of VX2 liver tumor. After that, some scheduled interventional experiments were carried out. Results: Imaging examination and histopathologic study showed that the successful rate of implanted rabbit VX2 liver tumor was 100% (40/40). And the successful rate of the catheter sheath inserted to femoral artery was 97.5% (39/40). The successful rate of celiac artery, gastro-hepatic artery, common hepatic artery, proper hepatic artery and left hepatic artery catheterizations was 100% (39/39), 100% (39/39), 100% (39/39), 94.9% (37/39) and 71.2% (28/39) respectively. Conclusion: To implant tumor tissue mass through laparotomy is a stable and reliable method to establish rabbit VX2 liver tumor model. The insertion of micro-catheter through rabbit femoral catheter sheath approach is a convenient and simple technique to be carried out for the left hepatic artery catheterization and it can efficiently solve the technical difficulties when performing the interventional treatment of the rabbit VX2 hepatic tumor via left hepatic artery approach.

    Background Isolated pulmonary valve stenosis (PS) makes up 6-9% of all congenital heart defects among children. The initial gold standard for diagnosis, follow-up of PS is by echocardiography. However, the most accurate diagnosis still remains to be measurement of the pressure gradient through transcatheterization. The purpose of this study is to compare the difference between the echocardiographic data to the cardiac catheterization data on the diagnosis, treatment, and follow-up in patients...

  1. Superiority of quantitative exercise thallium-201 variables in determining long-term prognosis in ambulatory patients with chest pain: a comparison with cardiac catheterization

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the prognostic utility of quantitative exercise thallium-201 imaging and compare it with that of cardiac catheterization in ambulatory patients. Accordingly, long-term (4 to 9 years) follow-up was obtained in 293 patients who underwent both tests for the evaluation of chest pain: 89 had undergone coronary artery bypass graft surgery within 3 months of testing and were excluded from analysis, 119 experienced no cardiac events and 91 had an event (death in 20, nonfatal myocardial infarction in 21 and coronary artery bypass operations performed greater than 3 months after cardiac catheterization in 50). When all variables were analyzed using Cox regression analysis, the quantitatively assessed lung/heart ratio of thallium-201 activity was the most important predictor of a future cardiac event (chi 2 = 40.21). Other significant predictors were the number of diseased vessels (chi 2 = 17.11), patient gender (chi 2 = 9.43) and change in heart rate from rest to exercise (chi 2 = 4.19). Whereas the number of diseased vessels was an important independent predictor of cardiac events, it did not add significantly to the overall ability of the exercise thallium-201 test to predict events. Furthermore, information obtained from thallium-201 imaging alone was marginally superior to that obtained from cardiac catheterization alone (p = 0.04) and significantly superior to that obtained from exercise testing alone (p = 0.02) in determining the occurrence of events. In addition, unlike the exercise thallium-201 test, which could predict the occurrence of all categories of events, catheterization data were not able to predict the occurrence of nonfatal myocardial infarction. The exclusion of bypass surgery and previous myocardial infarction did not alter the results

    To assess feasibility of proper hepatic artery catheterization using a 3D model obtained from preprocedural computed tomographic angiography (CTA), fused with real-time fluoroscopy, during transarterial chemoembolization of hepatocellular carcinoma. Twenty consecutive cirrhotic patients with hepatocellular carcinoma undergoing transarterial chemoembolization were prospectively enrolled onto the study. The early arterial phase axial images of the preprocedural CTA were postprocessed on an independent workstation connected to the angiographic system (Innova 4100; GE Healthcare, Milwaukee, WI), obtaining a 3D volume rendering image (VR) that included abdominal aorta, splanchnic arteries, and first and second lumbar vertebrae. The VR image was manually registered to the real-time X-ray fluoroscopy, with the lumbar spine used as the reference. The VR image was then used as guidance to selectively catheterize the proper hepatic artery. The procedure was considered successful when performed with no need for intraarterial contrast injections or angiographic acquisitions. The procedure was successful in 19 (95 %) of 20 patients. In one patient, celiac trunk angiography was required for the presence of a significant ostial stenosis that was underestimated at computed tomography. Time for image reconstruction and registration was <10 min in all cases. The use of preprocedural CTA model with fluoroscopy enables confident and direct catheterization of the proper hepatic artery with no need for preliminary celiac trunk angiography, thus reducing radiation exposure and contrast media administration.

    Objective: To evaluate feasibility administration of thymosin and Huangqi through the portal vein catheterization. And an assessment of the effects of the interventional therapy on the cellular immunity in the patients with chronic hepatitis B. Methods: Thymosin and Huangqi solution were given via portal vein catheterization in eight cases of chronic hepatitis B with hepatic carcinoma. The CD3, CD3+CD8+, CD3+CD4+, and NK cell level of peripheral blood were analyzed by flow cytometry pre- and post-operatively. Results: The level of CD3 was pre-operative 665.63 ± 434.80/μlvs post-operative 1326.50 ± 551.09/μl; CD3+CD8+ was 275.63 ± 205.78/μl vs 513.50 ± 231.00/μl; CD3+CD4+ was 515.88 ± 329.75 μl vs 981.75 ± 478.54/μl; and NK was 130.86 ± 176.58/μl vs 303.43 ± 190.90/μl, respectively. There were significance difference between pre-operative and post-operative data. Conclusion: The administration of thymosin and Huangqi via the portal vein catheterization is an effective and safe therapy to improve cellular immunity in patients with chronic hepatitis B, and potentially is a new treatment of chronic hepatitis B. Study of larger sample is expected. (authors)

    Full Text Available OBJECTIVE: To report the hemodynamic and functional responses obtained with clinical optimization guided by hemodynamic parameters in patients with severe and refractory heart failure. METHODS: Invasive hemodynamic monitoring using right heart catheterization aimed to reach low filling pressures and peripheral resistance. Frequent adjustments of intravenous diuretics and vasodilators were performed according to the hemodynamic measurements. RESULTS: We assessed 19 patients (age = 48±12 years and ejection fraction = 21±5% with severe heart failure. The intravenous use of diuretics and vasodilators reduced by 12 mm Hg (relative reduction of 43% pulmonary artery occlusion pressure (P<0.001, with a concomitant increment of 6 mL per beat in stroke volume (relative increment of 24%, P<0.001. We observed significant associations between pulmonary artery occlusion pressure and mean pulmonary artery pressure (r=0.76; P<0.001 and central venous pressure (r=0.63; P<0.001. After clinical optimization, improvement in functional class occurred (P< 0.001, with a tendency towards improvement in ejection fraction and no impairment to renal function. CONCLUSION: Optimization guided by hemodynamic parameters in patients with refractory heart failure provides a significant improvement in the hemodynamic profile with concomitant improvement in functional class. This study emphasizes that adjustments in blood volume result in imme-diate benefits for patients with severe heart failure.

    The use of checklists is recommended for the assessment of competency in central venous catheterization (CVC) insertion. To explore the use of a global rating scale in the assessment of CVC skills, this study seeks to compare its use with two checklists, within the context of a formative examination using simulation. Video-recorded performances of CVC insertion by 34 first-year medical residents were reviewed by two independent, trained evaluators. Each evaluator used three assessment tools: a ten-item checklist, a 21-item checklist, and a nine-item global rating scale. Exploratory principal component analysis of the global rating scale revealed two factors, accounting for 84.1% of the variance: technical ability and safety. The two checklist scores correlated positively with the weighted factor score on technical ability (0.49 [95% CI 0.17-0.71] for the 10-item checklist; 0.43 [95% CI 0.10-0.67] for the 21-item checklist) and negatively with the weighted factor score on safety (-0.17 [95% CI -0.48-0.18] for the 10-item checklist; -0.13 [95% CI -0.45-0.22] for the 21-item checklist). A checklist score of 80% on both checklists. All these candidates committed serious errors. In conclusion, the practice of universal adoption of checklists as the preferred method of assessment of procedural skills should be questioned. The inclusion of global rating scales should be considered. PMID:21877217

    The radial artery (RA) is a commonly used conduit for coronary artery bypass grafting, and recent studies have demonstrated that it provides superior long-term patency rates to the saphenous vein in most situations. In addition, the RA is also being used with increasing frequency as the access point for coronary angiography and percutaneous coronary interventions. However, there has been concern for many years that these transradial procedures may have a detrimental impact on the function of RA grafts used in coronary artery bypass grafting, and there is now comprehensive evidence that such interventions cause morphologic and functional damage to the artery in situ. Despite this, there remain remarkably few studies investigating the use of previously cannulated RAs as grafts in coronary artery bypass surgery, and there are no clear guidelines on the use of the RA in coronary artery bypass grafting after its catheterization. This article will review concisely the evidence that transradial procedures cause damage to the RA, and discuss the impact this could have on previously cannulated RAs used as coronary artery bypass grafting conduits. On the basis of the evidence assessed, we make a number of recommendations to both surgeons and cardiologists regarding use of the RA in cardiovascular procedures. PMID:27572880

    Full Text Available OBJECTIVE Anesthetic management for interventional cardiac procedures/cardiac catheterization in pediatric patients is challenging. Cardiac anomalies vary from simple to complex congenital cardiac anomalies, shunts may be present at multiple levels and patients may be profoundly cyanotic, may be with ventricular dysfunction. They usually require sedation and analgesia to maintain steady stable state. In adults, such type of procedures can be well managed with local anesthesia. METHODS Fifty patients were included in the study. They were randomly divided into two groups- Group A (n=25 patients received femoral N. block along with IV sedation and analgesia while group B (n=25 patients received only IV sedation and analgesia. Both groups were compared for hemodynamics, pain score and requirement of IV anesthetic agents and any complications if come up. RESULTS Group A patients required IV ketamine 3.24mg/kg (±0.31SD as compared to 5.58mg/kg (±1.6SD in group B, which suggests significantly reduced requirement of IV anesthetic agents in group where femoral nerve block has been given. Hemodynamic parameters remained stable and comparable (no statistically significant variation Pain score was less in group A patients than group B. CONCLUSION It has been observed that Group A patients required less dosages of IV anesthetic agents, with stable hemodynamics and less pain score and sedation score as compared to group B patients.

    Background Hemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension.Methods A prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours. Pulmonary artery systolic, diastolic and mean pressure (PASP, PADP and PAMP), cardiac output (CO), and pulmonary capillary wedge pressure (PCWP) were measured by both methods. A linear correlation and a Bland-Altman analysis were performed to compare the two groups of hemodynamic parameters.Results A good correlation was found between invasive and non-invasive measurements for PASP (r=0.96), PADP (r=0.85), PAMP (r=0.88), CO (r=0.82), and PCWP (r=0.81). Further agreement analysis done by the Bland-Altman method showed that bias and a 95% confidence interval for PASP, PADP, and CO were clinically acceptable while great discrepancies existed for PAMP and PCWP.Conclusions The non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.

    For wild and domestic felids, electroejaculation (EE) is the most common semen collection method. However, the equipment is expensive, there is a risk of urine contamination and animals usually show strong muscular contraction despite general anesthesia. Accordingly, we tested the feasibility of a different approach using urethral catheterization (UC) in seven African lions, previously described for domestic cats only. After general anesthesia with the α2-agonist medetomidine (which also stimulates semen release into the urethra) and ketamine, a transrectal ultrasound was performed to locate the prostate. A commercial dog urinary catheter (2.6 or 3.3 mm in diameter) was advanced approximately 30 cm into the urethra to allow semen collection into the lumen of the catheter by capillary forces. After retraction, sperm volumes between of 422.86 ± 296.07 μl yielded motility of 88.83 ± 13.27% (mean ± SD) with a mean sperm concentration of 1.94 × 10(9)/ml. Here we describe a simple, field friendly and effective method to attain highly concentrated semen samples with excellent motility in lions and potentially other wild felid species as an alternative to electroejaculation.

    We present a feasibility study on hybrid echocardiography (echo) and x-ray image guidance for cardiac catheterization procedures. A self-tracked, remotely operated robotic arm with haptic feedback was developed that attached to a standard x-ray table. This was used to safely manipulate a three-dimensional (3D) trans-thoracic echo probe during simultaneous x-ray fluoroscopy and echo acquisitions. By a combination of calibration and tracking of the echo and x-ray systems, it was possible to register the 3D echo images with the 2D x-ray images. Visualization of the combined data was achieved by either overlaying triangulated surfaces extracted from segmented echo data onto the x-ray images or by overlaying volume rendered 3D echo data. Furthermore, in order to overcome the limited field of view of the echo probe, it was possible to create extended field of view (EFOV) 3D echo images by co-registering multiple tracked echo data to generate larger roadmaps for procedure guidance. The registration method was validated using a cross-wire phantom and showed a 2D target registration error of 3.5 mm. The clinical feasibility of the method was demonstrated during two clinical cases for patients undergoing cardiac pacing studies. The EFOV technique was demonstrated using two healthy volunteers.

    One of the major complications of clean intermittent catheterization (CIC) is urinary tract infection (UTI). Recent reports showed that community-acquired UTIs caused by antimicrobial-resistant pathogens were gradually presenting in adults. However, there have been few reports about UTIs caused by antimicrobial-resistant bacteria in pediatric patients. Therefore, we retrospectively reviewed the medical charts of 45 children with CIC due to neurogenic bladder dysfunction from January 2010 to March 2013. Sixty-two episodes of cystitis occurred in 27 patients. Seventy bacterial strains were isolated from urine samples. The rate of Gram-negative bacteria was 84.3%. Six extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) strains were isolated from 4 patients. An ESBL-producing Proteus mirabilis strain and a methicillin-resistant Staphylococcus aureus strain were isolated from one patient each. Most of the pathogens of cystitis in the pediatric patients with CIC were Gram-negative bacilli, especially E. coli. We should be aware that ESBL producing E. coli as potential pathogens cause cystitis and regularly survey antimicrobial susceptibility to understand the resistant strains that develop. PMID:26194974

    Full Text Available Background: Catheterization of Internal Jugular Vein (IJV is commonly attempted to obtain central venous access for hemodynamic monitoring, long term administration of fluids, total parenteral nutrition and hemodialysis in critical care patients. The safe puncture of the IJV is achieved by using anatomical land marks on skin surface. Ultrasound guidance could be beneficial in placing central venous catheters by improving the success rate, reducing the number of needle passes, decreasing access time and decreasing complications. Material and Methods: Sixty critical care patients were selected for IJV cannulation either by land mark technique or by ultrasound guided technique in two groups of thirty each. Results: In our study there was 100% success rate for first attempt cannulation in USG technique and where as it was 83.3% in LMG technique. The mean access time in USG technique was 152.50 ± 63.90 sec as against 323.23 ± 146.19 sec in LMG group. Conclusion: Ultrasound guided technique improves the cannulation of the IJV with respect to safety, rapidity and comfort to the patient during the procedure.

  14. Suspension model for blood flow through a catheterized arterial stenosis with peripheral layer of plasma free from cells

    The present article describes the blood flow in a catheterized artery with radially symmetric and axially asymmetric stenosis. To understand the effects of red cell concentration, plasma layer thickness and catheter size simultaneously, blood is considered by a two-layered model comprising a core region of suspension of all the erythrocytes (particles) supposed to be a particle-fluid mixture and a peripheral zone of cell-free plasma. The analytical expressions for flow features, such as fluid phase and particle phase velocities, flow rate, wall shear stress and resistive force are obtained. It is witnessed that the presence of the catheter causes a substantial increase in the frictional forces on the walls of arterial stenosis and catheter, shear stress and flow resistance, in addition to that, have occurred due to the presence of red cells concentration (volume fraction density of the particles) and the absence of peripheral plasma layer near the wall of the stenosed artery. The introduction of an axially asymmetric nature of stenosis and plasma layer thickness causes significant reduction in flow resistance. One can notice that the two-phase fluid (suspension model) is more profound to the thickness of peripheral plasma layer and catheter than the single-phase fluid.

    Full Text Available PURPOSE: To determine adherence rate and variables associate with patients' adherence to Clean Intermittent Self Catheterization (CISC. MATERIALS AND METHODS: Patients refereed to CISC training program between July 2006 and May 2008, were prospectively evaluated with urodynamic, 3 days bladder diary (BD and WHOQoL-bref questionnaire. After training to perform CISC, patients were evaluated at 2 weeks, monthly for 6 months and at 12 months with clinical visits and BD. Patients were considered adherent if they were performing at least 80% of the initial recommendation. RESULTS: Sixty patients (50.4 ± 19.9 years old were trained to perform CISC (21 female and 39 male. Out of them, 30 (50% had neurogenic and 30 (50% had a non-neurogenic voiding dysfunction. The adherence rate at 6 and 12 months was 61.7%, 58%, respectively. Patients < 40 years old had adherence rate of 86%. Women and neurogenic patients had higher adherence rate than their counterparts (p = 0.024 and p = 0.016, respectively. In the WHOQoL-bref, patients that adhere to the program had a significant higher score on psychological and social relationships domains. There was not difference in pre and post training WHOQoL-bref scores. Educational background, marriage status, detrusor leak point pressure, Bladder Capacity, number of leakage episodes did not play a role on the adherence rate. CONCLUSION: Patients in CISC program present a reasonable adherence after one year. Women, neurogenic voiding dysfunction and patients under 40 years old were significantly more adherents. The psychological and social relationship status seems to positively interfere on adherence. CISC did not affect patient's QoL evaluated by WHOQoL-bref.

Si bien el grupo es pequeño es suficiente para mostrar que la punción repetida de la arteria radial es factible y permite una alta tasa de éxito de los procedimientos con una disminución ostensible de las complicaciones locales.The radial artery approach for percutaneous cardiac interventions has gained worldwide acceptance due to the similar results obtained by the femoral artery access. In this paper, we report our experience with repeated puncture of the radial artery. One hundred and eighty two radial artery access procedures were performed, in 17 interventions the puncture was repeated once or twice, with a total of 20 therapeutic catheterizations (9 coronary angiographies, 11 angioplasties. There was no therapeutic failure through the radial approach but, we successfully gained access in 88.2% (15/17 of the re-interventions cases. Although an experience with a low number of cases, we had a very high successful therapeutic rate, and also a remarkable lowering of local complications, this shows the feasibility and potential of this technique.

    Objective: To study the correlation of low-dose 64-row multi-detector computed tomography (MDCT) with echocardiography and cardiac catheterization angiography (CCA) in the assessment of pulmonary arterial anatomy in children with cyanotic congenital heart disease (CCHD). Materials and methods: This prospective study included 105 children (74 males, 31 females) with CCHD, in the age group of 2 months to 20 years, who underwent 64-row MDCT examination (low-dose CT protocol), echocardiography and CCA for the assessment of pulmonary arteries, including visualization, presence of confluence, stenosis and collaterals. Statistical analysis was performed using the non-parametric statistical analysis test to evaluate the concordance or discordance between echocardiography, MDCT and CCA. Results: 64-row MDCT detected significantly more main and branch pulmonary arteries, patent pulmonary confluences, and more cases of pulmonary artery stenosis. CCA detected more major aorto-pulmonary collaterals than MDCT, whereas echocardiography failed to identify these major aorto-pulmonary collaterals. The effective CT radiation dose to patients less than 2 years of age was in the range of 0.7–2.5 mSv, where as the dose in patients more than 2 years of age ranged from that of 2.1 to 4.2 mSv, which is much less than the radiation dose reported in cardiac catheterization angiography. Conclusion: In cases where cardiac MRI cannot be performed, or is not sufficiently informative, low-dose 64-row MDCT correlates well with CCA and can provide adequate information about pulmonary arterial anatomy in children with cyanotic congenital heart disease, and can replace invasive cardiac catheterization angiography with markedly reduced radiation dosage to the patient.

    Cardiac output during right-sided heart catheterization is an important variable for patient selection of advanced therapies (cardiac transplantation and left ventricular assist device implantation). The Fick method to determine cardiac output is commonly used and typically uses estimated oxygen consumption (VO2) from 1 of 3 published empirical formulas. However, these estimation equations have not been validated in patients with heart failure and reduced ejection fraction (HFrEF). The objectives of the present study were to determine the accuracy of 3 equations for estimating VO2 compared with direct measurement of VO2 and determine the extent clinically significant error occurred in calculating cardiac output of patients with HFrEF. Breath-by-breath measurements of VO2 from 44 patients who underwent cardiac catheterization (66% men; age, 65 ± 11 years, left ventricular ejection fraction, 22 ± 6%) were compared with the derived estimations of LaFarge and Miettinen, Dehmer et al, and Bergstra et al. Single-sample t tests found only the mean difference between the estimation of LaFarge and Miettinen and the measured VO2 to be nonsignificant (-10.3 ml/min ± 6.2 SE, p = 0.053). Bland-Altman plots demonstrated unacceptably large limits of agreement for all equations. The rate of ≥25% error in the equations by LaFarge and Miettinen, Dehmer et al, and Bergstra et al occurred in 11%, 23%, and 45% of patients, respectively. Misclassification of cardiac index derived from each equation for 2 clinically important classifications: cardiogenic shock-21%, 23%, and 32% and hypoperfusion-16%, 16%, and 25%; respectively. In conclusion, these findings do not support the use of these empiric formulas to estimate the VO2 at rest in patients with HFrEF who underwent right-sided heart catheterization. PMID:26443561

Urinary liver-type fatty acid binding protein (L-FABP increases along with tubular hypoxia and may be a detector of systemic circulation injury. The aim of this study was to evaluate the clinical usefulness of detecting increases in urinary L-FABP levels due to administration of CM, as a prognostic biomarker for cardiovascular disease in patients without occurrence of CM-induced nephropathy undergoing cardiac catheterization procedure (CCP. Methods: Retrospective longitudinal analyses of the relationship between urinary L-FABP levels and occurrence of cardiovascular events were performed (n=29. Urinary L-FABP was measured by ELISA before CCP, and at 6, 12, 24, and 48 hours after CCP. Results: Urinary L-FABP levels were significantly higher at 12 hours (P<0.05 and 24 hours (P<0.005 after CCP compared with before CCP, only in the patients with occurrence of cardiovascular events (n=17, but not in those without cardiovascular events (n=12. The parameter with the largest area under the curve (0.816 for predicting the occurrence of cardiovascular events was the change in urinary L-FABP at 24 hours after CCP. The difference in urinary L-FABP levels (ΔL-FABP ≥11.0 µg/g creatinine between before CCP and at 24 hours after CCP was a risk factor for the occurrence of cardiovascular events (hazard ratio, 4.93; 95% confidence interval, 1.27–19.13; P=0.021. Conclusion: Measurement of urinary L-FABP before CCP and at 24 hours after CCP in patients with mild to moderate renal dysfunction may be an important indicator for risk

    Full Text Available Medication errors are the most common cause of iatrogenic adverse events. They can lead to severe complications, including prolonged hospitalization, unnecessary diagnostic tests and treatments, and even death. Objective:We set to explore the impact of introducing standardized cath lab order forms on medication errors, quality of patient care and staff satisfaction. This was a single center observational study conducted in a tertiary cardiac center in Saudi Arabia. We enrolled a total of 100 consecutive patients who underwent diagnostic or interventional cardiac catheterization before or after the introduction of standardized order forms. The cohort was divided into two equal groups. We compared medication prescription errors (as defined by hospital formulary between the two groups. We also studies the impact of the standardized order forms on peri-procedural care including laboratory tests order completion, peri-procedural fluid and diabetes management, anticoagulant, diuretic and analgesia management. We have also employed a structured questionnaire to assess staff satisfaction with the use of these forms implementation of standardized order forms resulted in significant reduction of prescription errors from 32.0% to 0.0% (p = 0.025. There was also a significant improvement in patient care as indicated by improvement in the rates of completion of laboratory orders that improved from 76.0% to 96.0% after the implementation of order forms (p = 0.004, proper fluid management (100% vs. 86.0%, p = 0.023 and better peri-procedural diabetic management (see attached table. There was also improvement in the monitoring of the vascular access site (80% vs. 100%, p = 0.004 that resulted in reduction in access site related complications (6% vs. 0%. We administered a satisfaction questionnaire to 61 participants (nurses, physicians and pharmacists.

    The aim of this study was to evaluate the influence that different protocols of urethral catheterization after pharmacological induction (Ur.Ca.P.I.) may have on the semen quality of the domestic cat. The study has been divided into two experiments: one in which different dosages of medetomidine administrated are evaluated and the second one in which the timing of the catheterization after pharmacological induction is tested. In the first experiment, 18 cats were sedated with the recommended dosage of medetomidine (130 μg/kg i.m.) while the other 18 were sedated with a lower dose of the same drug (50 μg/kg i.m.). In the second experiment, three groups were implemented, each containing 25 subjects. In group 1, the semen collection was performed immediately once the pharmacological effect of the drug was reached; in group 2, the semen collection was performed three times every 5 min after the pharmacological effect was reached; finally, in group 3, Ur.Ca.P.I. was performed 20 min after the pharmacological effect was reached. All the different protocols permitted sperm collection, nevertheless the first experiment showed a better quality in terms of volume, concentration, total number of spermatozoa (p sedation with 130 μg/kg of medetomidine leads to a better quality sperm collection than 50 μg/kg does.

    Children diagnosed with congenital heart disease often undergo cardiac catheterization for their treatment, which involves the use of ionizing radiation and therefore a risk of radiation-induced cancer. The purpose of this study was to calculate the effective and equivalent organ doses (H{sub T}) in those children and estimate the risk of exposure-induced death. Fifty-three children were divided into three groups: atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). In all procedures, the exposure conditions and the dose-area product meters readings were recorded for each individual acquisition. Monte Carlo simulations were run using the PCXMC 2.0 code and mathematical phantoms simulating a child's anatomy. The H{sub T} values to all irradiated organs and the resulting E and risk of exposure-induced death values were calculated. The average dose-area product values were, respectively, 40 {+-} 12 Gy.cm{sup 2} for the ASD, 17.5 {+-} 0.7 Gy.cm{sup 2} for the VSD and 9.5 {+-} 1 Gy.cm{sup 2} for the PDA group. The average E values were 40 {+-} 12, 22 {+-} 2.5 and 17 {+-} 3.6 mSv for ASD, VSD and PDA groups, respectively. The respective estimated risk of exposure-induced death values per procedure were 0.109, 0.106 and 0.067%. Cardiac catheterizations in children involve a considerable risk for radiation-induced cancer that has to be further reduced. (orig.)

    To assess the incidence of and risk factors for acute adverse drug reactions (ADRs) (occurring within 1 h) following iopromide administration in cardiac catheterization in Chinese 'real-world' practice. Acute ADRs following iopromide administration during coronary angiography or percutaneous coronary intervention (PCI) have not been systematically evaluated in China. TRUST was a prospective, multicenter, observational study conducted at 63 centers in China. Patients received iopromide (300 or 370 mgI/mL) during coronary angiography or PCI (n = 17,513). Acute ADRs occurred in 66 patients (0.38%); ADRs were mild in 58 patients (0.33%) and severe in two patients (0.01%). Most acute ADRs manifested as allergy-like symptoms such as nausea/vomiting [39 patients (0.22%)] and/or rash [15 patients (0.09%)]. The rate of acute ADRs was lower among patients who received premedication (6/3349; 0.18 %) than those who did not (60/14,164; 0.42%; p = 0.0379), and among those who did receive pre-procedural hydration (10/7993; 0.13%) compared with those who did not (56/9520; 0.59%; p contrast media increased the risk of ADRs, while premedication with corticosteroids, pre-procedural hydration and contrast volume Contrast quality was rated as 'Excellent' in 99.1% of patients. The incidence of acute ADRs was very low with iopromide in cardiac catheterization in China. The risk of acute ADRs increased in patients contrast media. Premedication with corticosteroids and pre-procedural hydration may prevent acute ADRs in at-risk patients. PMID:26058857

  9. Quantification of aortic valve area at 256-slice computed tomography: Comparison with transesophageal echocardiography and cardiac catheterization in subjects with high-grade aortic valve stenosis prior to percutaneous valve replacement

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to compare planimetric aortic valve area (AVA) measurements from 256-slice CT to those derived from transesophageal echocardiography (TEE) and cardiac catheterization in high-risk subjects with known high-grade calcified aortic stenosis. Methods and materials: The study included 26 subjects (10 males, mean age: 79 ± 6; range, 61-88 years). All subjects were clinically referred for aortic valve imaging prior to percutaneous aortic valve replacement from April 2008 to March 2009. Two radiologists, blinded to the results of TEE and cardiac catheterization, independently selected the systolic cardiac phase of maximum aortic valve area and independently performed manual CT AVA planimetry for all subjects. Repeated AVA measurements were made to establish CT intra- and interobserver repeatability. In addition, the image quality of the aortic valve was rated by both observers. Aortic valve calcification was also quantified. Results: All 26 subjects had a high-grade aortic valve stenosis (systolic opening area 2) via CT-based planimetry, with a mean AVA of 0.62 ± 0.18. In four subjects, TEE planimetry was precluded due to severe aortic valve calcification, but CT-planimetry was successfully performed with a mean AVA of 0.46 ± 0.23 cm2. Mean aortic valve calcium mass score was 563.8 ± 526.2 mg. Aortic valve area by CT was not correlated with aortic valve calcium mass score. A bias and limits of agreement among CT and TEE, CT and cardiac catheterization, and TEE and cardiac catheterization were -0.07 [-0.37 to 0.24], 0.03 [-0.49 to 0.55], 0.12 [-0.39 to 0.63] cm2, respectively. Differences in AVA among CT and TEE or cardiac catheterization did not differ systematically over the range of measurements and were not correlated with aortic valve calcium mass score.

    Purpose: The purpose of this study was to compare planimetric aortic valve area (AVA) measurements from 256-slice CT to those derived from transesophageal echocardiography (TEE) and cardiac catheterization in high-risk subjects with known high-grade calcified aortic stenosis. Methods and materials: The study included 26 subjects (10 males, mean age: 79 {+-} 6; range, 61-88 years). All subjects were clinically referred for aortic valve imaging prior to percutaneous aortic valve replacement from April 2008 to March 2009. Two radiologists, blinded to the results of TEE and cardiac catheterization, independently selected the systolic cardiac phase of maximum aortic valve area and independently performed manual CT AVA planimetry for all subjects. Repeated AVA measurements were made to establish CT intra- and interobserver repeatability. In addition, the image quality of the aortic valve was rated by both observers. Aortic valve calcification was also quantified. Results: All 26 subjects had a high-grade aortic valve stenosis (systolic opening area <1.0 cm{sup 2}) via CT-based planimetry, with a mean AVA of 0.62 {+-} 0.18. In four subjects, TEE planimetry was precluded due to severe aortic valve calcification, but CT-planimetry was successfully performed with a mean AVA of 0.46 {+-} 0.23 cm{sup 2}. Mean aortic valve calcium mass score was 563.8 {+-} 526.2 mg. Aortic valve area by CT was not correlated with aortic valve calcium mass score. A bias and limits of agreement among CT and TEE, CT and cardiac catheterization, and TEE and cardiac catheterization were -0.07 [-0.37 to 0.24], 0.03 [-0.49 to 0.55], 0.12 [-0.39 to 0.63] cm{sup 2}, respectively. Differences in AVA among CT and TEE or cardiac catheterization did not differ systematically over the range of measurements and were not correlated with aortic valve calcium mass score.

  11. Evaluation of a simple radionuclide procedure for left-to-right cardiac shunt measurement - correlation with earpiece densitometry and cardiac catheterization

    International Nuclear Information System (INIS)

    Measurement of shunts from systemic to pulmonary circulation using a simple radionuclide technique has been introduced at our department. A good bolus of the Technetium-99m sodium pertechnetate at a dose of 200 μCi/kg body weight (minimal dose 2 mCi) was injected by way of a scalp vein needle connected to a three-way stopcock, thus permitting immediate flushing of the radioactive bolus dose with physiologic saline solution. An IGE-400A gamma camera with a low-energy, high-sensitivity parallel hole collimator was used. The data were stored for analysis on a Star computer at a rate of 4 frames/second for a 40-second period. Twenty-three patients (aged 3-33 years) underwent first pass radionuclide angiography and cardiac catheterization to estimate the degree of systemic-to-pulmonary shunting (QP/QS) ratio). In 15 of these patients, another non-invasive method, earpiece densitometry (EPD), was done to determine the size of the shunt qualitatively. Fifteen healthy volunteers submitted to first pass studies comprised our control group. Out of the 23 patients with shunts, 15 had simple intra-cardiac septal defects (atrial or ventricular) or patent ductus arteriosus, and 8 had valvular lesions plus shunts. Compared with the oximetry data, EPD resulted in misclassification of 5 out of 15 patients in that left-to-right shunts were interpreted as moderate in 4, i.e. QP/QS 2:1, when in fact they were smaller. The correlation coefficient value of the first pass method for simple defect is r=0.89 (A=0.41 and B=0.85), for combined lesions it is r=0.94 (A=0.1 and B=1.1). The mean value for QP:QS in 15 normal subjects is 1.06:1 (SD=± 0.05). We conclude that first pass radionuclide angiography is a non-invasive and reliable method for determining QP/QS ratios. Unlike cardiac catheterization, it can be performed rapidly on an out-patient basis. (orig./TRV)

    After childhood Kawasaki syndrome (KS) the coronary arteries undergo a lifelong dynamic pathological change, and follow-up coronary artery imaging is essential. At present, conventional coronary catheterization (CCC) and angiography is still regarded as the gold standard. Less-invasive methods such as multidetector CT angiography (MDCT-A) and MRI have been used sporadically. To compare the diagnostic quality of MDCT-A and MRI with that of CCC for coronary imaging in a group of patients with coronary artery pathology after childhood KS. A total of 16 patients (aged 5-27 years) underwent CCC and 16-row MDCT-A and 14 patients MRI (1.5 T). There was 100% agreement between MDCT-A and CCC in the detection of coronary aneurysms and stenoses. MDCT-A was superior for the visualization of calcified lesions. MRI and CCC showed 93% agreement for the detection of aneurysms. Visualization of coronary artery stenoses was difficult using MRI - one stenosis was missed. MDCT-A has excellent correlation with CCC regarding all changes affecting the coronary arteries in the follow-up of childhood KS. In comparison to MDCT-A and CCC, MRI is less precise in the detection of stenotic lesions. Due to its high image quality and ease of performance MDCT-A should be the primary diagnostic modality in patients following childhood KS. (orig.)

    Full Text Available Introduction: We aimed to develop a classification method to discriminate ventricular septal defect and atrial septal defect by using severalhemodynamic parameters.Patients and Methods: Forty three patients (30 atrial septal defect, 13 ventricular septal defect; 26 female, 17 male with documentedhemodynamic parameters via cardiac catheterization are included to study. Such parameters as blood pressure values of different areas,gender, age and Qp/Qs ratios are used for classification. Parameters, we used in classification are determined by divergence analysismethod. Those parameters are; i pulmonary artery diastolic pressure, ii Qp/Qs ratio, iii right atrium pressure, iv age, v pulmonary arterysystolic pressure, vi left ventricular sistolic pressure, vii aorta mean pressure, viii left ventricular diastolic pressure, ix aorta diastolicpressure, x aorta systolic pressure. Those parameters detected from our study population, are uploaded to multi-layered artificial neuralnetwork and the network was trained by genetic algorithm.Results: Trained cluster consists of 14 factors (7 atrial septal defect and 7 ventricular septal defect. Overall success ratio is 79.2%, andwith a proper instruction of artificial neural network this ratio increases up to 89%.Conclusion: Parameters, belonging to artificial neural network, which are needed to be detected by the investigator in classical methods,can easily be detected with the help of genetic algorithms. During the instruction of artificial neural network by genetic algorithms, boththe topology of network and factors of network can be determined. During the test stage, elements, not included in instruction cluster, areassumed as in test cluster, and as a result of this study, we observed that multi-layered artificial neural network can be instructed properly,and neural network is a successful method for aimed classification.

    One of the most treatable causes of lower back pain and associated sciatica is lumbar disc herniation (LDH), which is characterized by rupture of the hard outer wall (annulus fibrosis) in a lumbar intervertebral disc. In the current study, we aimed to: (1) develop and characterize a rat model of sciatica induced by LDH, while introducing a novel method of epidural catheterization; (2) use this model to evaluate the effect of osthole on pain due to LDH, and (3) gain insight into the mechanisms through which osthole affects sciatica induced by LDH. The results indicate that our newly developed rat model maintained mechanical allodynia for 28 days without reduction. Moreover, cyclooxygenase-2 (COX-2) and nitric oxide synthase (NOS) were overexpressed in the associated inflammatory response, which is consistent with clinical manifestations of the disease. We then used this model to study the effect and mechanisms through which osthole affected pain due to LDH. Our study suggests that osthole is capable of reversing hyperalgesia due to LDH, potentially through modulation of activity of COX-2 and NOS, two important proteins for the exacerbation of pain due to LDH. Finally, a molecular modeling simulation showed that osthole has unique binding capabilities to both NOS and COX-2. As the model-induced mechanical hyperalgesia response was consistent, and the position of the catheter tip and the extension/spreading of the drug in the epidural space were reliable, this study developed an improved model to study remedies for sciatic pain. Moreover, our studies demonstrate that osthole may be a feasible treatment for the reduction of pain due to hyperalgesia. PMID:23018204

    Background Primary percutaneous coronary intervention (PCI) has been clearly identified as the first therapeutic option for patients with acute ST-segment elevation myocardial infarction (STEMI). The importance of reducing door-to-balloon (D2B) time has gained increased recognition. This study aimed to assess the feasibility, safety and efficacy of the strategy of direct ambulance transportation of patients with acute STEMI to catheterization lab to receive primary PCI.Methods The study population included 141 consecutive patients with chest pain and ST-segment elevation who were admitted to the catheterization laboratory directly by the ambulance and underwent primary PCI (DIRECT group).Another 145 patients with STEMI randomly selected from the PCI database, were served as control group (conventional group); they were transported to catheterization laboratory from emergency room (ER). The primary endpoint of D2B time,and secondary endpoint of in-hospital and 30-day major adverse cardiac events (MACE, including death, non-fatal reinfarction, and target vessel revascularization) were compared.Results Baseline and procedural characteristics between the two groups were comparable, except more patients in the DIRECT group presented TIMI 0-1 flow in culprit vessel at initial angiogram (80.1% and 73.8%, P=0.04). Comparing to conventional group, the primary endpoint of D2B time was reduced ((54±18) minutes and (112±55) minutes, P <0.0001)and the percentage of patients with D2B <90 minutes was increased in the DIRECT group (96.9% and 27.0%, P<0.0001).The success rate of primary PCI with stent implantation with final Thrombolysis in Myocardial Infarction (TIMI) 3 flow was significantly higher in the DIRECT group (93.8% and 85.2%, P=0.03). Although no significant difference was found at 30-day MACE free survival rate between the two groups (95.0% and 89.0%, P=0.06), a trend in improving survival status in the DIRECT group was demonstrated by Kaplan-Meier analysis

    Background: Right ventricular function predicts outcome in patients with pulmonary hypertension (PH). Therefore accurate assessment of right ventricular function is essential to graduate severity, assess follow-up, and response to therapy. Purpose: To evaluate whether PH severity could be assessed using electrocardiography-gated CT (ECG-gated CT) functional parameters. A further objective was to evaluate cardiac output (CO) using two ECG-gated CT methods: the reference Simpson technique and the fully automatic technique generated by commercially available cardiac software. Material and Methods: Our institutional review board approved this study; patient consent was not required. Twenty-seven patients who had undergone ECG-gated CT and right heart catheterization (RHC) were included. Two independent observers measured pulmonary artery (PA) diameter, PA distensibility, aorta diameter, right ventricular cardiac output (CT-RVCO) and right ventricular ejection fraction (CT-RVEF) with automatic and Simpson techniques on ECG-gated CT. RHC-CO and mean pulmonary arterial pressure (mPAP) were measured on RHC. Relationship between ECG-gated CT and RHC measurements was tested with linear regression analysis. Results: Inter-observer agreement was good for all measurements (r > 0.7) except for CT-RVCO calculated with Simpson's technique (r = 0.63). Pulmonary artery (PA) distensibility was significantly correlated to mPAP (r = -0.426, P = 0.027). CT-RVEF was correlated with mPAP only when issued from Simpson technique (r = -0.417, P = 0.034). CT-RVEF was not significantly correlated to RHC-CO (P > 0.2). CT-RVCO measured with Simpson technique (r = 0.487, P = 0.010) and automatic segmentation (r = 0.549, P 0.005) correlated equally with RHC-CO. Conclusion: CT-RVEF and CT-RVCO measured on ECG-gated CT are significantly correlated, respectively, to mPAP and RHC-CO in this population with severe reduction of the right ventricular ejection fraction and could be useful for

    本文报告骶管麻醉在小儿先天性心脏病心导管和心血管造影术中的应用.骶管麻醉组44例,静脉麻醉12例.结果,骶管麻醉组并发症明显低于单纯静脉麻醉.骶管麻醉不仅有助于导管操作和造影时体位固定,且有利于代谢和血流动力的稳定.%This paper reports the use of caudal anaesthesia in cardiac catheterization and angiocardiaography on children with congenital heart diseases,and the comparison between it and the intravenous anaesthesia on the basis of their angiocardiographic data.In the group of caudal anaesthesia(44 cases),1-1.75% procaine and 0.1-0.15% dicaine solution with adrenaline(1ml /Kg body weight)were given.Intermittent increments of Valium or Ketamine was administered when necessary.Intravenous anaesthesia was applied to 12 cases(Group Ⅱ)with Ketamine and α-hydroxybutyrat or Valium.Results:43.18% of the patients in Group Ⅰ did not require increments of intravenous anaesthetics,but 13 cases Ketamine was given(dosage:0.85-0.49 mg/kg/hr).Ketamine was administered unexceptionally in GroupⅡ with a dosage of 1.61-0.84 mg/kg/hr.There was significant difference between the two groups in the dosage of Ketamie(p<0.02).The caudal anaesthsia group had a much lower occurrence of complications as compared with those who received intravenous anaesthesia alone.The authors considered that caudal anaesthesia is better than intravenous anaethsia in angiocardiography in pediatric cases,for it keeps the pateint well immobulized and makes catheter manipulation easier,and also provides a stable metabolic and haemodynamic condition.

    Purpose: To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients. Material and Methods: The study was performed prospectively in a randomized manner. The success and immediate complication rates of radiologically guided placement of central venous access catheters through the internal jugular vein (n = 40) were compared with those of the anatomical landmark method (n 40). The success of placement, the complications, the number of passes required, and whether a single or double-wall puncture occurred were also noted and compared. Results: The groups were comparable in age and sex. The indication for catheter placement was hemodialysis access in all patients. Catheter placement was successful in all patients in group 2 and unsuccessful in 1 (2.5%) patient in group 1. All catheters functioned adequately and immediately after the placement (0% initial failure rate) in group 2, but 3 catheters (7.5% initial failure rate) were non-functional just after placement in group 1. The total number of needle passes, double venous wall puncture, and complication rate were significantly lower in group 2. Conclusion: Percutaneous central venous catheterization via the internal jugular vein can be performed by interventional radiologists with better technical success rates and lower immediate complications. In conclusion, central venous catheterization for emergent dialysis should be performed under both real-time ultrasound and fluoroscopic guidance.

    Purpose: until now, no mechanical closure devices were available to achieve fast and secure hemostasis for vessel closure after catheterization of small arterial vessels. Material and methods: eighty patients were randomized to evaluate the effect on hemostasis by use of a chitosan pad (Chito-Seal, Abbott Vascular Devices, Galway/Ireland) in comparison to manual compression after diagnostic transbrachial arterial catheterization. Hemostasis after three minutes and one hour as well as local development of a hematoma after one and twenty-four hours were assessed. Results: the use of chitosan pads significantly decreased the bleeding time in the first three minutes after manual compression time (p < 0.01). Significant decrease in bleeding risk at three minutes by use of the chitosan closure pads was also found in subgroups of patients with hypertension (p < 0.001) or diabetes (p < 0.01) and also in patients under anticoagulation therapy (p < 0.01). In addition, long-term protection from bleeding complications such as the risk of hematoma was decreased by the use of chitosan closure pads one hour (p < 0.01) or twenty-four hours (p < 0.001) after catheter removal. Conclusion: the use of an intravascular anchor or suture system is not safely applicable in these vessels due to the small diameter of the brachial artery. Our results document a significant improvement in hemostasis by using chitosan pads in these cases. (orig.)

    Full Text Available Several protective measures have been described to prevent contrast-induced nephropathy (CIN. This study is aimed to evaluate the effect of a high dose of N-acetylcysteine (NAC plus hydration, a low dose of NAC plus ascorbic acid and hydration or hydration alone on the prevention of CIN in high-risk patients undergoing elective coronary artery intervention. We conducted a randomized, prospective, placebo-controlled trial of 105 high-risk patients undergoing elective cardiac catheterization. The patients were divided into three different groups: Group A (n = 30, NAC 1200 mg orally before angiography and 1200 mg orally twice daily for three doses along with good hydration; Group B (n = 30, NAC 600 mg before angiography and 600 mg orally twice daily for three doses plus ascorbic acid (3000 mg one dose before angiography and 2000 mg two doses after angiography and good hydration; and Group C (n = 45, hydration with 0.9% saline started just before contrast media injection and continued for 12 h at a rate 1.0 mL/kg/min after angiography or 0.5 mL/kg/h in cases with overt heart failure for 12 h. CIN was defined as an increase in serum creatinine of >25% of baseline or an absolute increase of 0.5 mg/dL above baseline after 48 h. The incidence of CIN was significantly lower in Group A (6.66% compared with Group B (16.66% or Group C (17.77%. The difference between Groups A and B and between Groups A and C was also highly significant (P = 0.001. In contrast, the difference between Groups B and C was not statistically significant (P = 0.37. Our study indicates that high doses of NAC plus hydration provide better protection against CIN than combination therapy of NAC and ascorbic acid plus hydration, or hydration alone.

    Radiodermatitis is a known complication in patients having undergone radiotherapy. It usually appears 2 to 5 years after irradiation. We are reporting on a case of radiodermatitis that occurred within months after coronary dilatation and stenting. It started with painful swelling, followed by a typical appearance on the skin surface. Histological finding confirmed the diagnosis. However, magnetic resonance imaging showed changes in the subcutaneous tissue extending into the ribs. A radical debridement was performed including removal of a partially necrotic 4th rib. The defect was closed with a latissimus dorsi transposition flap. Our findings are compared with the literature reports

    Increasingly, imaging administrators are gaining oversight for the cardiac cath lab as part of imaging services. Significant daily challenges include physician and staff demands, as well as patients who in many cases require higher acuity care. Along with strategic program driven responsibilities, the management role is complex. Critical elements that are the major impacts on cath lab management, as well as the overall success of a cardiac and vascular program, include program quality, patient safety, operational efficiency including inventory management, and customer service. It is critically important to have a well-qualified cath lab manager who acts as a leader by example, a mentor and motivator of the team, and an expert in the organization's processes and procedures. Such qualities will result in a streamlined cath lab with outstanding results. PMID:22720540

    Objective To establish rabbit model of embolic middle cerebral artery occlusion stroke with clots through selective transfemoral internal carotid catheterization(ICA), and evaluate the feasibility and stability of the technique. Methods A total of 30 New Zealand white rabbits were enrolled, either gender, with mean age of 14-month old and mean body weight of 4.1 kg, which were divided into control group(n=10) and experimental group(n = 20). Both groups received selective transfemoral ICA and angiography, with 1-5 clots injected in experimental group and only the contrast media injected in control group. Digital subtraction angiography (DSA) was performed to observe cerebral vascular obstruction, the modified Bederson scoring was used to observe neurologic impairment, CT perfusion was performed to observe cerebral blood perfusion, and diffusion weighted imaging (DWI) and 2, 3, 5 -triphenyltetrazolium chloride (TTC) staining were used to observe cerebral infarction. Results Seventeen (85 %) embolic rabbit stroke models in experimental group were successfully established, which manifested occlusion of middle cerebral arteries, neurologic deficits, abnormalities of perfusion, DWI and TTC staining. Three embolic rabbit stroke models were failed, because internal carotid arteries were occluded in 2 rabbits and recanalization occurred in occluded middle cerebral artery in 1 rabbit. No abnormality was observed in control animals. There was obvious difference in CT parameters between 2 groups. Conclusion It is demonstrated that the technique for establishing rabbit models of embolic middle cerebral arteries occlusion stroke with clots through selective transfemoral ICA is simple, micro invasive and reliable. Selection of appropriate clots and familiarity with the anatomy and variation of ICA could obviously improve the stability and reproducibility of focal cerebral ischemia model in rabbits.%目的 经股动脉途径行选择性颈内动脉插管建立兔大脑中动

    Full Text Available OBJECTIVE: to seek the best evidence available in the literature concerning the knowledge produced and related to the techniques of intermittent and indwelling urinary catheterization, so as to place the nursing care given to patients submitted to urinary catheterization on a scientific foundation and to prevent urinary tract infections. METHOD: the literature search was undertaken in the Pubmed and Cochrane databases for the development of the integrative review. The sample was of 34 articles. These were analyzed by two independent researchers using an instrument adapted for ascertaining the level of evidence and the grade of recommendation, in addition to the use of the Jadad scale. RESULTS: the evidence available related to the nursing care for patients submitted to urinary catheterization is: the infection rate in the urinary tract does not alter whether the perineum is cleaned with sterile water or not, or with the use of povidone-iodine solution or chlorhexidine; or using clean or sterile technique. The use of an intermittent catheter with clean technique results in low rates of complications or infections compared to the use of an indwelling catheter. The removal of the catheter in up to 24 hours after surgery and the use of an antimicrobial-impregnated or hydrophilic-coated catheter reduce urinary tract infection . CONCLUSIONS: there are controversies in relation to periurethral cleansing technique, the type of material the catheter is made of, and some procedures for the maintenance and removal of the catheter. This review's results represent an updating of the nurse's conducts and decision-making for the prevention of urinary tract infections in urinary catheterization.OBJETIVO: buscar las mejores evidencias disponibles en la literatura sobre el conocimiento producido y relacionado a la técnica de cateterismo urinario intermitente y de demora para apoyar científicamente el cuidado de enfermería prestado al paciente sometido al

    Prior validation studies have established that simultaneously measured catheter (cath) and Doppler mean pressure gradients (MPG) correlate closely in evaluation of aortic stenosis (AS). In clinical practice, however, cath and Doppler are rarely performed simultaneously; which may lead to discrepant results. Accordingly, our aim was to ascertain agreement between these methods and investigate factors associated with discrepant results. We reviewed findings in 100 consecutive evaluations for AS performed in 97 patients (mean age 72 +/- 10 yr) in which cath and Doppler were performed within 6 weeks. We recorded MPG, aortic valve area (AVA), cardiac output, and ejection fraction (EF) by both methods. Aortic root diameter, left ventricular end-diastolic dimension (LVIDd) and posterior wall thickness (PWT) were measured by echocardiography and gender, heart rate, and heart rhythm were also recorded. An MPG discrepancy was defined as an intrapatient difference > 10 mmHg. Mean pressure gradients by cath and Doppler were 36 +/- 22 mmHg and 37 +/- 20 mmHg, respectively (P = 0.73). Linear regression showed good correlation (r = 0.82) between the techniques. An MPG discrepancy was found in 36 (36%) of 100 evaluations; in 19 (53%) of 36 evaluations MPG by Doppler was higher than cath, and in 17 (47%) of 36, it was lower. In 33 evaluations, EF differed by >10% between techniques. Linear regression analyses revealed that EF difference between studies was a significant predictor of MPG discrepancy (P = 0.004). Women had significantly higher MPG than men by both cath and Doppler (43 +/- 25 mmHg versus 29 +/- 15 mmHg [P = 0.001]; 42 +/- 23 mmHg versus 32 +/- 15 mmHg [P = 0.014], respectively). Women exhibited discrepant results in 23 (47%) of 49 evaluations versus 13 (25%) of 51 evaluations in men (P = 0.037). After adjustment for women's higher MPG, there was no statistically significant difference in MPG discrepancy between genders (P = 0.22). No significant interactions between MPG and aortic root diameter, relative wall thickness (RWT), heart rate, heart rhythm, cardiac output, and time interval between studies were found. In clinical practice, significant discrepancies in MPG were common when cath and Doppler are performed nonsimultaneously. No systematic bias was observed and Doppler results were as likely yield lower as higher MPGs than cath. EF difference was a significant predictor of discrepant MPG. Aortic root diameter, relative wall thickness, heart rate, heart rhythm, cardiac output, presence or severity of coronary artery disease, and time interval between studies were not predictors of discrepant results.

  20. Improved radiation protection for physicians performing cardiac catheterization

    International Nuclear Information System (INIS)

    Physicians and their assistants performing diagnostic angiography must be concerned with the radiation exposure they receive. The introduction of hemiaxial projections for imaging has increased diagnostic accuracy but has also greatly increased the physicians' exposure to scattered radiation. This increase is especially critical for the eyes and thyroid of the physician who routinely performs these procedures. To reduce such exposure a ceiling-suspended shield (60 x 45 cm), made of 6.4 mm glass with a 19.5 kg/m2 (4 lb/ft2) lead equivalency, was developed. During procedures the shield is interposed between the physician and the region of the patient acting as the source of scattered radiation. The degree of radiation protection to the operator was assessed by measuring the distribution of scattered radiation in the vicinity of the operator with and without the shield. The effectiveness of the shield was determined in the 30 degrees right anterior oblique (RAO), 5 degrees left anterior oblique (LAO), 35 degrees LAO, and 50 degrees LAO-15 degrees cranial angulations. At critical heights such as the level of the eyes and thyroid, scattered radiation levels were reduced by 85% or greater in all angulations. Without interfering with the physician's ability to observe the patient or manipulate the catheter, this shield can significantly reduce the physician's exposure to radiation

    Full Text Available Aims and Objectives: The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. Materials and Methods: We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. Results: Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552. Conclusions: The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.

    Full Text Available OBJECTIVES: Evaluate the safety and effectiveness of a training program for performing ultrasound-guided internal jugular vein cannulation in critically ill patients. METHODS: Cohort prospective study, evaluating adult patients admitted in a teaching intensive care unit (ICU. Catheter placement was performed by an ICU medical resident. The patient's baseline characteristics, vessel's position and operator experience were the evaluated variables. The main outcomes were cannulation success rate and incidence of major complications. RESULTS: A total of 118 consecutive patients were enrolled between May 2008 and November 2009. The success rate of ultrasound guided catheter placement was 90% (106/118, 77% in the first attempt. Major complications occurred in 4% of the cases (n = 5 and were not associated with the analyzed variables. Inability to place the guide wire was the reason for 58% (7/12 of the failures. Operators with more than 15 previous ultrasound guided cannulations had an increased success rate (95% vs. 79%, p = 0.01 and increased failure was related to previous catheterization (26% vs. 7%, p = 0.02.

  13. Second Report. Dose reduction of occupational exposure during cardiac catheterization and angiography

    International Nuclear Information System (INIS)

    Since X-ray fluoroscopy in the IVR has tended to take longer than usual diagnosis, exposure of medical personnel to scattered X-rays has increased and become a problem. The authors report the results of a questionnaire survey to investigate the types of devices currently being used in medical facilities to protect against scattered X-ray exposure. Questionnaires were distributed to a total of 71 medical facilities, and replies were obtained from 57 (80%). Many facilities used ''ceiling-suspended types'', as commercially available devices, and ''examining-table fixed type'' and ''mobile type'' devices were described as self-manufactured devices in some facilities. The overall evaluation of protective devices yielded opinions such as ''time-consuming'', ''restricted imaging directions'' and expensive'', and the mobile-type devices were said to involve the problem of taking up a great deal of space in the fluoroscopy room. In regard to the problems or degree of satisfaction with the devices, 75% answered ''we have some problems'', but a reply of ''unsatisfactory'' was obtained from only one facility. The results of this survey show that popularization of protective devices and reduction of exposure depend on ''consideration of operator exposure'' and that it is important to increase awareness of exposure and the need for protective devices.

Currently, they are part of the standard medical care for oncohematologic patients. However, apart from mechanical and thrombotic complications, there are also complications associated with biofilm development inside the catheters. These biofilms increase the cost of medical assistance and extend hospitalization. The most frequently involved micro-organisms in these infections are gram-positive cocci. Many efforts have been made to understand biofilm formation within the lumen catheters, and to resolve catheter-related infection once it has been established. Apart from systemic antibiotic treatment, the use of local catheter treatment (ie, antibiotic lock technique is widely employed. Many different antimicrobial options have been tested, with different outcomes, in clinical and in in vitro assays. The stability of antibiotic concentration in the lock solution once instilled inside the catheter lumen remains unresolved. To prevent infection, it is mandatory to perform hand hygiene before catheter insertion and manipulation, and to disinfect catheter hubs, connectors, and injection ports before accessing the catheter. At present, there are still unresolved questions regarding the best antimicrobial agent for catheter-related bloodstream infection treatment and the duration of concentration stability of the antibiotic solution within the lumen of the port.

  15. Local homodynamic changes induced by radial artery catheterization with color doppler ultrasound

    International Nuclear Information System (INIS)

    Objective: To examine the possible local damaging effects of arterial monitoring catheters on arterial functioning in patients after elective surgery with color Doppler ultrasound. Methods: Thirty patients who underwent elective surgery with a radial artery catheter were examined. The 2-dimentional ultrasonography and the blood flow of each radial and ulnar artery were examined before the puncture, 30 minutes and 24-hour after removal. Artery diameter, peak velocity of blood flow and patency were examined. The blood flow velocity of ulnar artery/the blood flow velocity of radial artery ratio were compared. The non-affected arm was used as the control. Results: Artery monitoring catheters caused a remarkable functional arterial change in the affected arm. The blood flow velocity of ulnar artery/the blood flow velocity of radial artery ratio were increased 30 minutes and 24 hour after removal. There were no severe clinical complications. Conclusion: Radial artery blood flow can be observed clearly with color Doppler ultrasound. Aseries of data were measured and recorded. There is significant change in the hemodynamic function of the artery during certain period of time. (authors)

    1989-01-01

    Infusion thrombophlebitis is a common troublesome complication of intravenous therapy. This study compared peripheral intravenous Teflon and Vialon catheters. The incidence of phlebitis, bacterial adherence and mechanical resistance (distortion) were assessed on 170 catheters, 85 of each type. The Vialon catheter resulted in less phlebitis than the Teflon one (18 vs. 35; p less than 0.01). During the period 49 to 72 h after the insertion of the catheter, the risk of phlebitis in the Teflon group was twice that in the Vialon group. The study of bacterial adherence using a semi-quantitative culture method demonstrated that 9.0% of the catheters were infected with Staphylococcus epidermidis. There was no statistically significant difference between the two groups (5.7% Vialon group vs. 12.5% Teflon group). The Teflon catheters were much more distorted than vialon catheters: 1.7% vs. 55.7% in the macroscopic study; 1.75% vs. 8.2% in the microscopic study. As Vialon softens at body temperature, it would seem likely that it generates a lesser degree of endothelial injury, explaining the lower rate of phlebitis with Vialon catheters. PMID:2633660

    Functional capacity is a robust predictor of clinical outcomes, and stress testing is used in current practice paradigms to guide referral to invasive coronary angiography. However, invasive coronary angiography is driven by ongoing symptoms, as well as risk of adverse outcomes. The limitations of current functional testing-based paradigms might be avoided by using coronary computed tomographic angiography (CCTA) for exclusion of obstructive coronary artery disease. The growth of CCTA has been supported by comparative prognostic evidence with CCTA and functional testing, as well as radiation dose reduction. Use of CCTA for physiological evaluation of coronary lesion-specific ischemia may facilitate evaluation of moderate stenoses, designation of the culprit lesion, and prediction of benefit from revascularization. The potential of CCTA to serve as an effective gatekeeper to invasive coronary angiography will depend, in part, on the adoption of these new developments, as well as definition of the benefit of detecting high-risk plaque for guiding the management of selected patients.

    Full Text Available Background: Contrast-induced nephropathy (CIN represents an increasing healthcare burden and challenge especially in the scenario of increasing frequency of diagnostic imaging and interventional procedures. Frequency of CIN varies widely depending on the population. There is paucity of data regarding CIN in our population. The risk of CIN is elevated and is of clinical importance in patients with estimated glomerular filtration rate (GFR 60 ml/mt and GFR 30 – 60 ml/mt. Patients who developed CIN were followed up with serum creatinine measurement on the 5th day post procedure. Results: Among 850 patients enrolled for the study, 15 patients were lost for follow-up. Of the rest 835 patients, 535(64% were having GFR > 60ml /mt and 300 (36% having GFR of 30-60 ml/mt. The procedure was coronary angiography in 795(95% patients and percutaneous coronary intervention (PCI in 40 (5% patients. CIN occurred in 5 patients (0.59 %. 3 of 300 patients in the group with GFR 30 – 60 ml/mt and 2 of 535 patients in the group with GFR > 60ml/mt had CIN (1% vs 0.4% (p value 0.260 NS. Among the 500 hypertensives in the study population, 3 (0.6% developed CIN.

    This article reports a rare case of acute pyelonephritis secondary to left ureteral obstruction by a bladder catheter. The patient was 93years old man hospitalized in the hospital emergency department with a 39°C fever and pyuria from an indwelling catheter. Blood test found hyperleukocytosis, inflammatory syndrome and acute renal failure. Diagnosis was confirmed by non-contrast abdominal CT scan showing distal part of the catheter inside left ureteral orifice with ureterohydronephrosis. Treatment consisted in replacing the catheter by a three-way catheter for irrigation and parenteral antibiotics therapy. Clinico-biological evolution was successful and a urinary tract CT scan could be realized at day 9. The left upper urinary tract function was recovered. With a short review of the literature we propose to describe the different procedures to manage those obstructions. PMID:25288585

A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years. (author)

    Full Text Available Peripheral nerve blockade (PNB is superior to neuraxial anesthesia and/or opioid therapy for perioperative analgesia in total knee replacement (TKR. Evidence on the safety of PNB in patients with coagulopathy is lacking. We describe the first documented account of continuous femoral PNB for perioperative analgesia in a patient with Von Willebrand Disease (vWD. Given her history of opioid tolerance and after an informative discussion, a continuous femoral PNB was planned for in this 34-year-old female undergoing TKR. A Humate-P intravenous infusion was started and the patient was positioned supinely. Using sterile technique with ultrasound guidance, a Contiplex 18 Gauge Tuohy needle was advanced in plane through the fascia iliaca towards the femoral nerve. A nerve catheter was threaded through the needle and secured without complications. Postoperatively, a levobupivacaine femoral catheter infusion was maintained, and twice daily Humate-P intravenous infusions were administered for 48 hours; enoxaparin thromboprophylaxis was initiated thereafter. The patient was discharged uneventfully on postoperative day 4. Given documentation of delayed, unheralded bleeding from PNB in coagulopathic patients, we recommend individualized PNB in vWD patients. Multidisciplinary team involvement is required to guide factor supplementation and thromboprophylaxis, as is close follow-up to elicit signs of bleeding throughout the delayed postoperative period.

    Myeloid sarcoma (MS) is a rare extramedullary myeloid tumour. It has been reported in various sites, including lymph node, bone, skin, soft tissue, various organs and the CNS. It may precede or occur concurrently with acute myeloid leukemia. Urinary bladder involvement is extremely uncommon. We report a 70-year-old female who had MS of the urinary bladder, presented with frank and persistent hematuria associated with lower abdominal pain. She subsequently had tumour seeding in the abdominal skin via percutaneous suprapubic catheter. Tumours from both the urinary bladder and skin showed immature cells that were immunoreactive toward LCA (focal), MPO (strong), CD99 (weak) and CD117 (weak). Summary of cases in the literature is presented. The potential of its misdiagnosis and the useful markers for the diagnosis of MS are discussed. PMID:21874752

    Coronary angiogram is an imperative tool for diagnosis of coronary artery diseases, in which cine-angiography is a commonly used method. Although the angiography proceeds under radiation, the potential risk of radiation exposure for both the patients and the operators was seldom noticed. In this study, the absorbed radiation dose in stored-fluorography mode was compared with that in cine-angiography mode by using optically simulated luminescent dosimeters to realize their effects on radiation dose. Patients received coronary angiogram via radial artery approach were randomized into the stored-fluorography group (N=30) or the cine-angiography group (N=30). The excluded criteria were: 1. women at pregnancy or on breast feeding, 2. chronic kidney diseases with glomerular filtration rate less than 60 mL/min. During the coronary angiogram, absorbed dose of the patients and the operator radiation exposure was measured with optically simulated luminescent dosimeter (OSLD). The absorbed dose of the patients in the stored-fluorography group (3.13±0.25 mGy) was apparently lower than that in the cine-angiography group (65.57±5.37 mGy; Pstatistical difference (P<0.001) was also found between the stored-fluorography group (0.09163 μGy) and the cine-angiography (0.6519μGy). Compared with traditional cine-angiography mode, the stored-fluorography mode can apparently reduce radiation exposure of the patients and the operator in coronary angiogram.

  10. Optimizing radiation protection of the operator during cardiac catheterization by minimizing the effective dose

    International Nuclear Information System (INIS)

    Radiation exposure dosimetry for the personnel is based on measurements of phantom studies. To determine effective dose values for different X-ray equipment, TLD-measurements were performed using an Alderson Phantom in the patient position and a second phantom in the typical position of the personnel. Various types of protective clothing as well as fixed shields were considered in the calculations. Additional thyroid protection collars reduce the effective dose by a factor of 1.8-2.6. In the sense of effective dose X-ray protective clothing with 0.35 mm lead equivalent and an additional thyroid protection collar provide a better protection against radiation than an apron with 0.5 mm lead equivalent without collar. The doses of the unshielded organs (thyroid, parts of the active bone marrow) contribute significantly to the effective dose of the staff. Therefore an additional shielding of these organs reduces the effective dose more than an increase of the lead equivalency of the existing apron. We recommend face shields and thyroid protection collars as a necessary part of anti-X protection for cardiac catherization laboratories. (author)

    The design principles that drove the development of a new cardiovascular x-ray digital flat panel (DFP) detector system are presented, followed by assessments of imaging and dose performance achieved relative to other state of the art FPD systems. The new system (GE Innova 2100 IQ TM) incorporates a new detector with substantially improved DQE at fluoroscopic (73%@1μR) and record (79%@114uR) doses, an x-ray tube with higher continuous fluoro power (3.2kW), a collimator with a wide range of copper spectral filtration (up to 0.9mm), and an improved automatic x-ray exposure management system. The performance of this new system was compared to that of the previous generation GE product (Innova 2000) and to state-of-the art cardiac digital x-ray flat panel systems from two other major manufacturers. Performance was assessed with the industry standard Cardiac X-ray NEMA/SCA and I phantom, and a new moving coronary artery stent (MCAS) phantom, designed to simulate cardiac clinical imaging conditions, composed of an anthropomorphic chest section with stents moving in a manner simulating normal coronary arteries. The NEMA/SCA&I phantom results showed the Innova 2100 IQ to exceed or equal the Innova 2000 in all of the performance categories, while operating at 28% lower dose on average, and to exceed the other DFP systems in most of the performance categories. The MCAS phantom tests showed the Innova 2100 IQ to be significantly better (p << 0.05) than the Innova 2000, and significantly better than the other DFP systems in most cases at comparable or lower doses, thereby verifying excellent performance against design goals.

    We report a 12-year-old boy who presented with abdominal pain and who was found to have an aneurysm of the abdominal aorta (AAA). The patient was born from a quadruplet pregnancy induced by in vitro fertilization. Postnatal transient respiratory distress required assisted ventilation that had been monitored by two consecutive umbilical arterial catheters (UAC). AAA is a rare condition in childhood. Infection and/or trauma are known to be the most frequent causes. Most of the reported cases have occurred in children in whom a UAC had been placed during the neonatal period. In this patient the delay between UAC placement and diagnosis was considerable. At the time of this report the patient had remained well during a follow-up of 8 years after treatment. (orig.)

    The purpose of the study is to assess the impact of superselective neurotransmitter metabolic therapy in patients in a vegetative state. Superselective intraarterial infusion was conducted on 26 patients with relevant international criteria for the diagnosis of vegetative state. Comprehensive assessment of neurologic symptoms and severity of low metabolism on PET scan allowed to select the vascular pool, for the catheter installation. The catheter was placed either in the carotid or the vertebrobasilar pool. Infusion of neurotransmitter agents was conducted for 7 days continuously. Control of the level of metabolism of labeled glucose in the brain (PET) was performed within 2 weeks after arterial infusion. 14 out of 26 patients showed a positive trend of changes in energy metabolism of the brain. However, only 7 out of 14 patients showed further recovery of consciousness. The data confirms that the delivery path and a combination of medications play a definite role in the effectiveness of vegetative state therapy. PMID:21692220

    In this paper, we have discussed the influence of copper nanoparticles on a blood flow through composite stenosed artery with permeable walls. The nature of blood is discussed mathematically by considering it as viscous nanofluid. The study is carried out for a blood vessel under mild stenosis approximations and expressions of the temperature, velocity, resistance impedance to flow, wall shear stress and the pressure gradient is obtained by using corresponding boundary conditions. Results for the effects of permeability on blood flow through composite stenosis have been discussed graphically. The considered analysis also summarizes that the drug copper nanoparticles are efficient to reduce hemodynamics of stenosis and could be helpful to predict important uses for biomedical applications. Results indicate that nanoparticles are helpful as drug carriers to minimize the effects of resistance impedance to blood flow or coagulation factors due to stenosis. PMID:27393802

  3. A new design of a lead-acrylic shield for staff dose reduction in radial and femoral access coronary catheterization

    International Nuclear Information System (INIS)

    Today's standard radiation protection during coronary angiography and percutaneous coronary interventions is the combined use of lead acrylic shields and table-mounted lower body protection. Ambient dose measurements, however, have shown that these protection devices need improvement. Using an anthropomorphic physical phantom, various scenarios were investigated with respect to personnel exposure: (a) enlarging the shield (b) adding a flexible protective curtain to the bottom side of the shield, and (c) application of radioprotective patient drapes. For visualization of the dose reduction effect, Monte Carlo simulations were performed. The flexible curtain in contact with the patient's body reduces the ambient dose rate at the operator's position by up to (87.5 % ± 7.1) compared to the situation with the bare shield. The use of both the flexible curtain and the patient drape reduces the ambient dose rate by up to (90.8 % ± 7). Similar results were achieved for the assisting personnel when they were positioned next to the operator. In addition, the enlarged shield provides better protection of the head region of tall operators. Adding a flexible protective curtain to the bottom side of the shield can protect operators from high doses, especially for body parts which are not protected by lead aprons, e.g. head, and eye lenses. This may be important with respect to lower dose limits for eye lenses in future. The protective effect in real-life working conditions is still being evaluated in an ongoing clinical study.

  7. Pooled comparison of regadenoson versus adenosine for measuring fractional flow reserve and coronary flow in the catheterization laboratory

    International Nuclear Information System (INIS)

    Background: Adenosine is the gold standard for augmenting coronary flow during fractional flow reserve (FFR) testing of intermediate coronary stenoses. However, intravenous infusion is time-consuming and intracoronary injection is subject to variability. Regadenoson is a newer adenosine alternative administered as a single intravenous bolus during nuclear stress testing, but its efficacy and safety during FFR testing have been evaluated only in small, single-center studies. Methods: We pooled data from 5 academic hospitals, in which patients undergoing clinically-indicated FFR prospectively underwent comparison of intravenous adenosine infusion (140–175 mcg/kg/min) versus regadenoson bolus (400 mcg). Hemodynamics and symptoms with adenosine were recorded until maximal hyperemia occurred, and after returning to baseline hemodynamics, regadenoson was administered and monitoring was repeated. In a subset of patients with coronary flow data, average peak velocity (APV) at the distal flow sensor was recorded. Results: Of 149 patients enrolled, mean age was 59 ± 9 years, 76% were male, and 54% underwent testing of the left anterior descending artery. Mean adenosine-FFR and regadenoson-FFR were identical (0.82 ± 0.10) with excellent correlation of individual values (r = 0.96, p < 0.001) and no difference in patient-reported symptoms. Four patients (2.6%) had discrepancies between the 2 drugs for the clinical decision-making cutoff of FFR ≤ 0.80. Coronary flow responses to adenosine and regadenoson were similar (APV at maximal hyperemia 36 cm/s for both, p = 0.81). Conclusions: Regadenoson single-bolus administration has comparable FFR, symptoms, and coronary flow augmentation when compared with standard intravenous adenosine infusion. With its greater ease of administration, regadenoson may be a more “user-friendly” option for invasive ischemic testing

    Background/Purpose: Compared with trans-femoral percutaneous coronary intervention (TFI), trans-radial PCI (TRI) has a lower risk of bleeding, access site complications and hospital costs, and is preferred by patients. However, TRI accounts for a minority of PCIs in the US, and there is currently little research that explores why. Methods/Material: We conducted a national survey in February 2013 to assess perceptions of TRI vs. TFI, and barriers to TRI adoption and implementation among interventional cardiologists employed by the US Veterans Health Administration (VHA), and linked these data to site-level TRI annual rates for 2013. Results: We received 78 completed surveys (32% response rate). Respondents at sites that perform few or no TRIs identified increased radiation exposure as the greatest barrier while at sites that perform a high percentage of TRIs respondents identified the steep learning curve as the greatest barrier. Majorities of survey respondents at all sites rated TRI as superior on 5 of 7 criteria, including patient comfort and bleeding complications, but rated TFI as superior on procedure time and procedure success. Conclusions: Even interventional cardiologists at sites that perform few or any TRIs recognized the superiority of TRI for patient comfort and safety, but rated it inferior to TFI on procedure time and technical results. Interventional cardiologists at high-TRI labs rated TRI as equivalent on procedure time and technical results. Efforts to increase TRI adoption and implementation may be more successful if they emphasize that procedure times and technical results depend on achieving proficiency. - Highlights: • Sites with few TRIs identified increased radiation exposure as the greatest barrier. • Sites with many TRIs identified the steep learning curve as the greatest barrier. • TFI was rated superior on procedure time and procedure success. • TRI was rated superior on all other criteria.

    The hierarchical interaction between electrical signals of the brain and heart is not fully understood. We hypothesized that the complexity of cardiac electrical activity can be used to predict changes in encephalic electricity after stress. Most methods for analyzing the interaction between the heart rate variability (HRV) and electroencephalography (EEG) require a computation-intensive mathematical model. To overcome these limitations and increase the predictive accuracy of human relaxing states, we developed a method to test our hypothesis. In addition to routine linear analysis, multiscale entropy and detrended fluctuation analysis of the HRV were used to quantify nonstationary and nonlinear dynamic changes in the heart rate time series. Short-time Fourier transform was applied to quantify the power of EEG. The clinical, HRV, and EEG parameters of postcatheterization EEG alpha waves were analyzed using change-score analysis and generalized additive models. In conclusion, the complexity of cardiac electrical signals can be used to predict EEG changes after stress.

Efforts to increase TRI adoption and implementation may be more successful if they emphasize that procedure times and technical results depend on achieving proficiency. - Highlights: • Sites with few TRIs identified increased radiation exposure as the greatest barrier. • Sites with many TRIs identified the steep learning curve as the greatest barrier. • TFI was rated superior on procedure time and procedure success. • TRI was rated superior on all other criteria

    Background: Adenosine is the gold standard for augmenting coronary flow during fractional flow reserve (FFR) testing of intermediate coronary stenoses. However, intravenous infusion is time-consuming and intracoronary injection is subject to variability. Regadenoson is a newer adenosine alternative administered as a single intravenous bolus during nuclear stress testing, but its efficacy and safety during FFR testing have been evaluated only in small, single-center studies. Methods: We pooled data from 5 academic hospitals, in which patients undergoing clinically-indicated FFR prospectively underwent comparison of intravenous adenosine infusion (140–175 mcg/kg/min) versus regadenoson bolus (400 mcg). Hemodynamics and symptoms with adenosine were recorded until maximal hyperemia occurred, and after returning to baseline hemodynamics, regadenoson was administered and monitoring was repeated. In a subset of patients with coronary flow data, average peak velocity (APV) at the distal flow sensor was recorded. Results: Of 149 patients enrolled, mean age was 59 ± 9 years, 76% were male, and 54% underwent testing of the left anterior descending artery. Mean adenosine-FFR and regadenoson-FFR were identical (0.82 ± 0.10) with excellent correlation of individual values (r = 0.96, p < 0.001) and no difference in patient-reported symptoms. Four patients (2.6%) had discrepancies between the 2 drugs for the clinical decision-making cutoff of FFR ≤ 0.80. Coronary flow responses to adenosine and regadenoson were similar (APV at maximal hyperemia 36 cm/s for both, p = 0.81). Conclusions: Regadenoson single-bolus administration has comparable FFR, symptoms, and coronary flow augmentation when compared with standard intravenous adenosine infusion. With its greater ease of administration, regadenoson may be a more “user-friendly” option for invasive ischemic testing.

  14. Clinical assessment of cardiac performance in chronic lung diseases by using RI multi-gated cardiac pool scan and pulmonary artery catheterization

    International Nuclear Information System (INIS)

    To evaluate biventricular function at rest and hypoxic load in patients with chronic lung diseases, we examined radionuclide angiography in 6 normal controls, 19 patients with chronic obstructive lung diseases (COLD), 14 patients with restrictive lung diseases (RLD), using ECG-gated cardiac blood pool scans, and 7 patients (3 COLD, 4 RLD) were examined by the pulmonary artery catheter. After suitable background correction, left and right ventricular ejection fractions (LVEF and RVEF) were calulated by the formula : RVEF or LVEF = (end-diastole counts- end-systole counts)/end-diastole counts. Cardiac performance was measured at rest and after 20 minutes low oxygen (15 %) load. The results were as follows: 1) RVEF (%) at rest in the RLD group (46.6 ± 8.3 %) was less than that in the control group, and the COLD group (48.7 ± 8.7 %, 48.4 ± 12.4 %). 2) The responses to hypoxia in the COLD group and the RLD group showed absolute increases in RVEF of 8.7 ± 14.1 % and 7.4 ± 8.9 %, and also, mean pulmonary pressure (MPAP), cardiac index (CI) and pulmonary vascular resistance were increased significantly. These results suggest that in patients with chronic lung diseases, RV functions are after-hypoxic load-dependent and multiple cardiac pool image would be of value in the estimation of cardiac performance.

    The management of refractory cardiac arrest during invasive coronary procedures has substantial logistical challenges and is typically associated with disappointing outcomes. We describe the case of a young woman with recalcitrant ventricular fibrillation due to acute anterior ST-elevation myocardial infarction caused by occlusion of her proximal left anterior descending artery. Survival without neurological deficit or organ failure was achieved following primary percutaneous reperfusion and a total of 52 min of intra-procedural chest compression support, made possible by the use of an automated chest compression device.

    In this paper there has been analysed the diagnostic value of the parameters of the diastolic function (Peak Filling Rate, PFR and Time to Peak Filling Rate, TPFR) which are not to be covered by invasive methods. To this examination we applied a recently discovered nuclearmedical method: we used the Nuclear Stethoscope and with it were able to investigate not only the systolic function (Ejection Fraction) but also the diastolic function (PFR, TPFR). In addition to this we undertook a floating catheter during exercise for the critical examination of the left ventricle. The examined patients consisted of 28 patients, suffering from Coronary Heart Disease, the majority of them after myocardial infarction. In patients suffering from CHD there may be found relations between the nuclearmedical parameters of the diastolic function and the pulmonary capillary wedge pressure as far as in all patients who showed a functional disturbance with the aids of invasive methods this could also be proved non-invasively.

    We report on 6 women with continuous urinary incontinence as a late complication of an indwelling urethral catheter for neurogenic bladder. Pressure necrosis by the balloon resulted in progressive destruction of the entire urethra, with subsequent incontinence despite the catheter. Surgical attempts at bladder neck closure to correct the incontinence generally have been unsuccessful. Instead of supravesical urinary diversion, we performed transvaginal closure of the bladder neck and percutaneous placement of a permanent suprapubic tube cystostomy. All 6 patients remained dry after closure and none has shown upper urinary tract deterioration at followup for as long as 5 years. PMID:4040980

    The purpose of this study was to evaluate the dose received by health professionals in the hemodynamic sector of a university hospital in Sao Paulo city. A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years. (author)

    In order to confirm the relation between stent struts and the jailed side branch (SB), the actual wire re-crossing position and the optimal wire re-crossing position during a bifurcation stenting, we developed the instant stent-accentuated three-dimensional optical coherence tomography (iSA 3D-OCT) system based on a novel algorithm. Stent struts in two-dimensional optical coherence tomography (2D-OCT) are represented as high-intensity line segments or spots in low-intensity background. Stent struts disappear and a vessel image is created by the mean filter followed by the minimum filter. A strut image is created by subtracting a vessel image from an original image, and accentuated. By adding a vessel image to a strut image, iSA 2D-OCT is created. It took only 3 s to accentuate stent struts of 100 frames by ImageJ with its macro program. By the iSA 3D-OCT system which consists of the console of OCT, the USB selector, USB cables, the USB flash drive, the computer, and three freeware programs, it took about 65 s from an export of the image data to an observation of iSA 3D-OCT semi-automatically. During a bifurcation stenting procedure, we could confirm the relation between stent struts and the jailed SB, the actual wire re-crossing position and the optimal wire re-crossing position. Using the iSA 3D-OCT system, a detailed process during a bifurcation PCI can be observed in very short waiting time, about 65 s. It is expected to improve the outcome of a complicated bifurcation PCI by the iSA 3D-OCT system. PMID:23355032

  4. Clinically Significant Contrast Induced Acute Kidney Injury after Non-Emergent Cardiac Catheterization - Risk Factors and Impact on Length of Hospital Stay

    International Nuclear Information System (INIS)

    Objective: To evaluate the frequency and risk factors associated with clinically significant contrast-induced nephropathy (CIN) in patients undergoing non-emergent coronary angiography. Study Design: Descriptive study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, from January 2005 to December 2007. Methodology: Case records of patients who underwent coronary angiography with a serum creatinine of >= 1.5 mg/dl at the time of procedure were evaluated. Clinically significant contrast induced nephropathy (CSCIN) was defined as either doubling of serum creatinine from baseline value within a week following the procedure or need for emergency hemodialysis after the procedure. Results: One hundred and sixteen patients met the inclusion criteria. Mean age was 64.0 +- 11.5 years, 72% were males. Overall prevalence of CIN was 17% (rise of serum creatinine by A= 0.5 mg/dl) while that of clinically significant CIN (CSCIN) was 9.5% (11 patients). Patients with CSCIN had significantly lower left ventricular ejection fraction (p = 0.03, OR: 0.24; 95% CI = 0.06 A= 0.91) and higher prevalence of cerebrovascular disease (p < 0.001, OR: 14.66; 95% CI = 3.30 - 65.08). Mean baseline serum creatinine was significantly higher, 3.0 +- 1.5 vs. 2.0 +- 1.1 mg/dl (p = 0.03, OR: 1.47; 95% CI = 1.03 - 2.11) whereas mean GFR estimated by Cockcroft-Gault formula was significantly lower at 25 +- 7.4 vs. 41.0 +- 14.6 ml/minute (p = 0.001, OR = 0.89, 95% CI = 0.84 A= 0.95) at the time of procedure in patients with CSCIN. Mean length of hospital stay was significantly higher in this group compared to those without CIN, 9.0 +- 5.1 vs. 3.0 +- 3.2 days (p = 0.001, OR = 1.31, 95% CI = 1.12 - 1.54). Multivariate analysis revealed low GFR (p = 0.001, OR = 0.88; 95% CI = 0.82 - 0.95) and low ejection fraction (p = 0.03, OR = 0.20; 95% CI = 0.04 - 0.91) to be independent factors associated with CSCIN. No significant differences were noted between the two groups in patients with hypertension, diabetes and heart failure. Conclusion: CSCIN is a significant concern in high risk groups despite prophylaxis. Patients with lower EF, cerebrovascular disease and low GFR at the time of procedure are more likely to have CIN.

    A hybrid X-ray and magnetic resonance imaging system (XMR) has been proposed as an interventional guidance for cardiovascular catheterisation procedure. However, very few hospitals can benefit from the XMR system because of its limited availability. In this paper we describe a new guidance strategy for cardiovascular catheterisation procedure. In our technique, intra-operative patient position is estimated by using a chest surface reconstructed from a photogrammetry system. The chest surface is then registered with the same surface derived from pre-procedure magnetic resonance (MR) images. The catheterisation procedure can therefore be guided by a roadmap derived from the MR images. Patients were required to hold the breath at end expiration during MRI acquisition. The surface matching accuracy is improved by using a robust trimmed iterative closest point (ICP) matching algorithm, which is especially designed for incomplete surface matching. Compared to the XMR system, the proposed guidance strategy is low cost and easy to set up. Experimental data were acquired from 6 volunteers and 1 patient. The patient data were collected during an electrophysiology procedure. In 6 out of 7 subjects, the experimental results show our method is accurate in term of reciprocal residual error (range from 1.66m to 3.75mm) and constant (closed-loop TREs range from 1.49mm to 3.55mm). For one subject, trimmed ICP failed to find the optimal transform matrix (residual = 4.89, TRE = 9.32) due to the poor quality of the photogrammetry-reconstructed surface. More studies are being carried on in clinical trials.

    Although a transradial approach (TRA) is considered feasible in many clinical situations, no data are available in patients undergoing orthotopic heart transplantation (OHT). Our goal was to randomly compare TRA versus a transfemoral approach (TFA) in this clinical setting. This single-center, prospective, randomized trial was conducted from January to November 2006, and all OHT patients scheduled for a control coronary angiography were randomized to receive TRA or TFA. The primary endpoint was the amount of contrast used during the procedure. The participating interventional cardiologists were intermediate-volume radial operators, and this was their initial experience of TRA in OHT patients. The analysis was performed according to the intention-to-treat principle. Overall, 49 patients (mean age, 55 ± 13 years; 74% male) were included in the trial: 26 patients were assigned to TRA, and 23 were assigned to TFA. A higher amount of contrast (147 mL [range, 113-175 mL] vs 105 mL [range, 86-127 mL]; P = .009), a longer fluoroscopy time (9.2 minutes [range, 6-12 minutes] vs 3.5 minutes [range, 3-5 minutes]; P < .001), a trend toward increased number of catheters used for left ostium cannulation, and a higher crossover rate (19% vs 0%; P = .03) were associated with TRA compared with TFA. Furthermore, patients treated with TRA exhibit a shorter hospital stay (6 [range 4-8]) compared with the other group (26 [range 24-28]) (P < .001). There were no significant differences between the 2 groups regarding total procedural time, and no vascular complications were reported in either group. For these operators with their first experience of TRA in OHT patients, TFA seemed to be more efficient. PMID:25498035

    Full Text Available OBJETIVO: Determinar a prevalência de estenose da artéria renal (EAR em pacientes submetidos a cineangiocoronariografia. MÉTODOS: Estudo prospectivo, considerando 1.656 cinean-giocoronariografias seguidas de aortografia, entre janeiro/2002 e fevereiro/2004, de pacientes encaminhados à cineangiocoronariografia diagnóstica com história ou não de hipertensão arterial sistêmica (HAS. RESULTADOS: Dos 1.656 pacientes, a idade média foi de 61,6 ± 11,8 anos, 53,8% eram do sexo masculino, 10,2% eram diabéticos, 63,8% apresentavam coronariopatia obstrutiva. A presença de EAR maior que 50% foi observada em 228 (13,8% pacientes, e em 25 (1,5% destes, ocorreu bilateralmente. A coronariopatia obstrutiva foi definida como estenose que causa redução do lúmen do vaso em 50% ou mais, em um, dois ou três vasos principais, denominados uniarterial, biarterial ou triarterial, respectivamente.A quantificação era realizada através da análise visual da angiografia. Comparando os grupos com e sem EAR > 50%, observou-se diferença estatisticamente significativa quanto a gênero, idade, ocorrência de diabete melito, PA e função ventricular esquerda. Não houve diferença significativa, no entanto, quanto à ocorrência de obstrução coronariana > 50%. Quando, porém, a EAR considerada é > 70%, observa-se diferença significativa quanto a PA, associação à obstrução coronariana > 50% e à disfunção ventricular esquerda, maiores no grupo com EAR. CONCLUSÃO: A prevalência de EAR neste estudo foi comparável àquela das grandes casuísticas da literatura e, em razão de sua importância pela associação com HAS e doença renal terminal (DRT e suas seqüelas, devemos estar atentos para seu diagnóstico angiográfico.OBJECTIVE: To determine the prevalence of renal artery stenosis (RAS in patients who have undergone cineangiocoronariography. METHODS: Prospective study of cineangiocoronariography and aortography examinations conducted between January 2002 and February 2004 on 1,656 hypertensive and normotensive patients who underwent the examinations to confirm the diagnosis of obstructive coronary artery disease or valve disease. RESULTS: The average age of the 1,656 patients was 61.6 ± 11.8 years. Eight hundred and ninety-one (53.8% were male, 169 (10.2% were diabetic and 1,054 (63.8% presented obstructive coronary artery disease. Renal stenosis greater than 50% was observed in 228 (13.8% patients, and 25 (1.5% had bilateral stenosis. Obstructive coronary artery disease was defined as stenosis greater than or equal to 50% of the vessel lumen, in one, two or three main arteries, classified as single, double or triple vessels, respectively. Quantification was conducted using visual analysis of the angiography. Comparison of the groups with and without renal artery obstruction > 50%, revealed significant statistical differences in relation to gender, age, diabetes mellitus, blood pressure and left ventricular function. However, no statistical difference was noted in relation to the occurrence of coronary artery obstructions > 50%. Nevertheless, renal artery obstructions > 70%, revealed significant differences in relation to blood pressure, coronary artery obstructions > 50% and left ventricular function, which were all higher in the renal artery obstruction group. CONCLUSION: The prevalence of RAS found in our study was comparable to that reported by major medical literature case studies. RAS is associated with systemic hypertension (SH, end-stage renal disease (ESRD and its sequelae, emphasizing how important it is that we are aware of possible candidates for angiographic diagnosis of this disease.

Methods 427 cases of detaining ure-thral catheter children from July 2009 to July 2011 in Children' s Hospital of Soochow University were collected, urine culture was done in the day before drawing tube,bacteriological culture was performed among any positive,drug sensitive test was conducted to the separated pathogen by Kir-Bauer AGAR diffusion method. Results Among 427 cases of detaining urethra) catheter urine samples of children,53 slrains( 12.4% ) of pathogenic bacteria were separated ,with gram-positive bacteria 31 cases,gram-negative bacteria 20 cases, candida albicans in 2 cases. Gram-positive cocci were highly resistant to rifampin( >77.8% ) ,and had a certain resistance to aminoglycosides, but were sensitive to the linezolid and vancomycin. Enterocoecus faecalis' s resistance to penicillin and levofloxacin were significantly lower than Enterococcus faecium.but almost all of them were resistant to dalfopris-lin. All of the Enterococcus faecium were resistant to penicillin,also had a very high resistance to levofloxacin( >87.5% ). Cram-negative bacteria had a high drug-resistant rate to 1 -3 generations and penicillins (about 75% ) ,were lowly resistant to imipen-em,amikaein, piperacillin-tazobactam, and cefoxitin( <30%). Conclusion Gram-positive enterocoecua and escherichia coli were primarily in urinary catheter related urinary tract infections,and showed multiple resistance;to different pathogens,sensitive drugs were quite different. Drug resistance should be tested before treatment.%目的 了解留置尿管相关性尿路感染(CAUTIU)的细菌谱及其对常用抗菌药物的耐药性,为临床合理使用抗菌药物提供参考.方法 收集苏州大学附属儿童医院小儿泌尿外科2009年7月-2011年7月住院期间留置导尿管患儿427例,在拔管前一天做尿培养,阳性者再行细菌学培养,分离的病原菌以Kir by-Bauer琼脂扩散法行药敏试验.结果 留置导尿管患儿427例尿液标本分离的病原菌53株(12.4%),其中革兰阳性细菌31例,革兰阴性细菌20例,白色念珠菌2例.革兰阳性球菌对利福平耐药率较高(>77.8%),对氨基糖苷类也有一定耐药,但对利奈唑胺和万古霉素都敏感.粪肠球菌对青霉素美及左氧氟沙星的耐药性显著低于屎肠球菌,而对达福普汀几乎全部耐药.屎肠球菌对青霉素全部耐药,对左氧氟沙星也有相当高的耐药性(>87.5%).革兰阴性杆菌对青霉素类及1~3代头孢菌素的耐药率均较高(75%左右),时亚胺培南、阿米卡星、哌拉西林他唑巴坦及头孢西丁的耐药率较低(<30%).结论 留置尿管相关性尿路感染以革兰阳性肠球菌及大肠埃希菌为主,出现多重耐药,不同病原菌敏感药物存在较大差异,建议用药前进行药物敏感试验,抗生素应交叉使用,必要时联合应用.

    Detrusor-external sphincter dyssynergia (DSD) is a debilitating problem in patients with spinal cord injury. DSD carries a high risk of complications, and even life expectancy can be affected. Management of this condition includes the use of antimuscarinic agents in combination with intermittent catheterization, indwelling urethral catheterization, suprapubic catheterization, and a variety of surgical options, depending on patient and physician preference. This paper will review the current literature and data on minimally invasive and endoscopic management of DSD. PMID:26826587

    1980-11-27

    Approximately 10 per cent of patients referred for coronary arteriography because of chest pain have angiographically normal coronary arteries and no other heart disease. We examined the functional status of 57 patients who had undergone catheterization (23 men and 34 women), all of whom were told that their hearts were normal, that their pain was noncardiac, and that no limitation on activity was necessary. At a mean follow-up time of 16 +/- 7.7 months, 27 of the 57 patients (47 per cent) still described their activity as limited by chest pain (before catheterization, 42 of 57 or 74 per cent); 29 of 57 (51 per cent) were unable to work (before catheterization, 36 of 57 or 63 per cent); and 25 of 57 (44 per cent) still believed that they had heart disease (before catheterization, 45 of 57 or 79 per cent). Use of medical facilities was significantly reduced after catheterization (P comunication and rehabilitation. PMID:7421961

    was a prospective observational study involving 1,062 elective fast-track THAs or TKAs, which were performed in 4 orthopedics departments between April and November 2013. Primary outcome was the incidence of POUR, defined by postoperative catheterization. Age, sex, anesthetic technique, type of...... increased the risk of POUR (OR = 1.5, 95% CI: 1.02-2.3; p = 0.04) whereas age, sex, and type of arthroplasty did not. Median IPSS was 6 in non-catheterized males and 8 in catheterized males (p = 0.02), but it was 6 in the females in both groups (p = 0.4). INTERPRETATION: The incidence of POUR in fast......-track THA and TKA was 40%, with spinal anesthesia and increased IPSS in males as predictive factors. The large variation in perioperative bladder management and in bladder volumes evacuated by catheterization calls for randomized studies to define evidence-based principles for treatment of POUR in the...

    Although uncommon, mycotic aneurysms in infants can be lethal because of the high risk of rapid expansion and rupture. Most catheter-associated mycotic aneurysms reported in the first year of life develop following umbilical artery catheterizations. We describe the sonographic detection of an early stage mycotic aneurysm in a 4-month-old following femoral artery catheterization complicated by methicillin-resistant Staphylococcus aureus (MRSA) septicemia. We also describe the sonographic and radiographic progression of this mycotic aneurysm before surgery. (orig.)

Pheochromocytoma rarely needs venous catheterization and blood sampling, since arteriography is almost always capable to visualize it. Scintigraphy alone is generally accurate enough to distinguish between bilateral hyperplasia and tumors in Cushing's and adrenogenital syndromes (100% of personal observations); only a tumoral situation benefits by venous catheterization. Blood samples and venography must be preceded by scintigraphy in Conn's syndrome

  1. From arteritis to mycotic aneurysm: visualization of the progression of mycotic aneurysm development following femoral arterial line insertion in an infant

    International Nuclear Information System (INIS)

    Although uncommon, mycotic aneurysms in infants can be lethal because of the high risk of rapid expansion and rupture. Most catheter-associated mycotic aneurysms reported in the first year of life develop following umbilical artery catheterizations. We describe the sonographic detection of an early stage mycotic aneurysm in a 4-month-old following femoral artery catheterization complicated by methicillin-resistant Staphylococcus aureus (MRSA) septicemia. We also describe the sonographic and radiographic progression of this mycotic aneurysm before surgery. (orig.)

    2016-08-01

    : Postoperative urinary retention (POUR) is the inability to void when the bladder is full after surgery. It is a common complication in postoperative patients, especially in patients undergoing spinal surgery. At our institution, patients who were discharged from the postanesthesia care unit (PACU) to the inpatient surgical unit typically had bladder distention and a bladder volume of more than 450 mL. In an effort to address this situation, an interprofessional group of advanced practice RNs and physicians formed a team, reviewed the existing literature, examined the PACU nursing practice guideline for evaluating and managing POUR, and devised a quality improvement (QI) project to raise the PACU nursing staff's awareness of the potential for POUR among postoperative patients and to develop an updated nursing practice algorithm for the evaluation and management of POUR in spinal surgery patients. A description of the QI process, including the revised algorithm and pre- and postintervention results, is reported here. In the preintervention group (n = 42), 19 indwelling urinary catheterizations were documented in patient records; no use of intermittent catheterization was documented. In the postintervention group (n = 43), seven indwelling urinary catheterizations were documented in patient records; the use of intermittent catheterization was documented in 11. As a result of our intervention, we decreased the number of indwelling urinary catheters inserted in the PACU, and supported the PACU nursing staff in more frequent and appropriate use of intermittent catheterization in patients undergoing spinal surgery.

    Full Text Available Introduction: Percutaneous subclavian vein catheterization is one of the most common invasive procedures performed in cardiac surgery. The aim of this study was to compare left and right subclavian vein catheter placement via the infraclavicular approach in patients who undergo coronary artery bypass graft (CABG surgery.Methods: This prospective, randomized clinical trial was performed in193 patients. The technique applied for cannulation was infraclavicular approach for both the right and the left sides. Subclavian vein of other side was attempted only when catheterization at initial side was unsuccessful at two attempts. The success and complication rates were compared for the two sides.Results: On193 patients, catheterization attempts were performed. 177 catheterizations (91.7% were successful during the first attempt, 105 (92.1% on the right side and 72 (91.1% on the left side. There was no significant difference between success rate and side of catheterization. Malposition of the catheter tip on the right side (9.6% was significantly more than the left side (0% (P= 0.003. The differences in other complications on two sides were statistically insignificant.Conclusion: Compared with the right side, insertion of the cannula on the left side resulted in fewer catheter tip misplacements. Incidence of cannulation failure and other complications were similar on both sides.

    The virulence of a urease-negative mutant of uropathogenic Proteus mirabilis and its wild-type parent strain was assessed by using a CBA mouse model of catheterized urinary tract infection. Overall, catheterized mice were significantly more susceptible than uncatheterized mice to infection by wild-type P. mirabilis. At a high inoculum, the urease-negative mutant successfully colonized bladders of catheterized mice but did not cause urolithiasis and was still severely attenuated in its ability to ascend to kidneys. Using confocal laser scanning microscopy and scanning electron microscopy, we demonstrated the presence of P. mirabilis within the urease-induced stone matrix. Alizarin red S staining was used to detect calcium-containing deposits in bladder and kidney tissues of P. mirabilis-infected mice. PMID:11748205

  5. Use of first-pass radionuclide angiography for evaluating left-sided heart regurgitation

    International Nuclear Information System (INIS)

    The first-pass radionuclide technique can be used to evaluate valvular regurgitation. Sixty-three patients were studied with cardiac catheterization and first-pass radionuclide angiography. The degree of regurgitation by cardiac catheterization was evaluated by using a ranking scale of 0-4, where 4 is severe regurgitation. The results were as follows: for nine patients, rank = 0, and percentage of regurgitation (mean +- SD) = 3.6 +- 5; for five patients, rank = 1 and percentage regurgitation = 15.8 +- 3; for 13 patients, rank = 2 and percentage regurgitation = 28.5 +- 14; for 16 patients, rank = 3 and percentage regurgitation = 41.5 +- 10; and for 19 patients, rank = 4 and percentage regurgitation 54.9 +- 13. A correlation coefficient of .90 between cardiac catheterization and the first-pass technique was calculated. The authors conclude that first-pass radionuclide angiography can quantitate valvular regurgitation and accurately differentiate between no, minimal, moderate, and severe valvular regurgitation

    Full Text Available Abstract Introduction Male urethral diverticula are rare. Patients with paraplegia may present with acquired diverticula as a result of prolonged catheterization. Diverticula may be asymptomatic or lead to lower urinary tract symptoms. Rarely, the diverticulum may initially present as a scrotal mass. Case presentation We report the case of a male 45-year-old Arab with paraplegia who presented with a mass in the peno-scrotal junction. He had in his medical history iterative prolonged urethral catheterizations associated with urine leakage through the urethral meatus upon applying compression. Diagnosis confirmation of urethral diverticula is obtained by retrograde urethrography. The patient underwent a diverticulectomy with urethroplasty. Conclusion Male acquired urethral diverticula can be found in patients who have a spinal cord injury because of prolonged urethral catheterization. Clinical presentations are different and sometimes can be misleading. Retrograde urethrography is the key to diagnosis and open surgery is the treatment of reference.

  8. Persistent elevation of neutrophil/lymphocyte ratio associated with new onset atrial fibrillation following percutaneous coronary intervention for acute st segment elevation myocardial infarction

    International Nuclear Information System (INIS)

    Increasing evidence suggests that inflammation plays an important role in initiation and maintaining of atrial fibrillation (AF). The Neutrophil to Lymphocyte (N/L) Ratio is an easily derived and readily available parameter that has emerged as marker of inflammation with predictive and prognostic value. We investigated the association between N/L ratio and incidence of atrial fibrillation in patients undergoing cardiac catheterization for acute ST-segment elevation myocardial infarction (STEMI). Methods: This cross sectional descriptive study was carried out at New York Hospital Queens. We retrospectively analysed clinical, hematologic and angiographic data of 290 patients who underwent coronary angiography with stent placement for acute ST-segment elevation myocardial infarction between 2008-2011. Results: Study cohort of 290 patients had mean age 63.3 ± 13.0 years consisting of 81.4% male. The N/L ratio was measured at time points: <6 hours pre-catheterization, <12, 48 and 96 hours post catheterization. Patients who developed AF (n=40, 13.8%), had higher post catheterization N/L ratios at 48 hours (median 5.23 vs 3.00, p=0.05) and 96 hours (median 4.67 vs 3.56, p=0.03), with no differences in the immediate pre and post procedural measurements, <6 hours pre catheterization (median 2.49 vs 2.82, p=0.467) and <12 hours post catheterization (median 5.93 vs 5.03, p=0.741) respectively. Conclusion: In conclusion, these findings support an inflammatory aetiology contributing to new onset AF following percutaneous coronary intervention for acute STEMI. Further studies are warranted to elucidate these findings. (author)

    Coronary allograft vasculopathy (CAV) is the leading cause of graft failure in pediatric heart transplant recipients, also adding to mortality in this patient population. Coronary angiography is routinely performed to screen for CAV, with conventional single-plane or bi-plane angiography being utilized. Dual-axis rotational coronary angiography (RA) has been described, mostly in the adult population, and may offer reduction in radiation dose and contrast volume. Experience with this in the pediatric population is limited. This study describes a single-institution experience with RA for screening for CAV in pediatric patients. The catheterization database at our institution was used to identify pediatric heart transplant recipients having undergone RA to screen for CAV. Procedural data including radiation dose, fluoroscopy time, contrast volume, and procedure time were collected for each catheterization. The number of instances in which RA was not successful, ECG changes were present, and CAV was detected were also collected for each catheterization. A total of 97 patients underwent 345 catheterizations utilizing RA. Median radiation dose-area product per kilogram was found to be 341.7 (mGy cm(2)/kg), total air kerma was 126.8 (mGy), procedure time was 69 min, fluoroscopy time was 9.9 min, and contrast volume was 13 ml. A total of 17 (2 %) coronary artery injections out of 690 could not be successfully imaged using RA. A total of 14 patients had CAV noted at any point, 10 of whom had progressive CAV. Electrocardiographic changes were documented in a total of 10 (3 %) RA catheterizations. Procedural characteristics did not differ between serial catheterizations. RA is safe and feasible for CAV screening in pediatric heart transplant recipients while offering coronary imaging in multiple planes compared to conventional angiography. PMID:26846123

    We measured the area exposure product and fluoroscopic time during pediatric diagnostic and interventional catheterization in 1156 infants, children, and adolescents with congenital heart diseases between June 1994 and September 1996. The area exposure product and fluoroscopic time were 4865±4560 gGycm2 and 47±29 min, respectively during diagnostic catheterization. These values were significantly (p2 and 74±40 min, respectively). We have not experienced any acute or late side effects of X-ray in our patients up to three years of follow-up. However, further follow up is required to evaluate the long term side effect of irradiation. (author)

    Intra-arterial infusion of chemotherapy into the ophthalmic artery for treatment of retinoblastoma has been realized after catheterization of the internal carotid and temporary balloon occlusion beyond the orifice of the ophthalmic artery, or more recently after superselective canulation of the ophthalmic artery by a microcatheter. The superselective catheterization of the ophthalmic artery could be cumbersome because of the implantation of the ostium on the carotid siphon or because of the tortuosity of the carotid siphon. We report our experience of using a retrograde approach through the posterior communicating artery that allows a more direct angle of access to the origin of the ophthalmic artery. (orig.)

A clinical case of HS following common carotid artery transposition and catheterization in a horse is described. The animal presented head and neck sweating with focal skin temperature elevation, facial paralysis and ptosis. Most clinical signs were transient and persisted for two hours following percutaneous catheter removal. Recurrence of clinical signs was observed at subsequent catheterizations. Ptosis endured for 10 months as a consequence of the first catheter placement which demonstrates the importance of careful manipulation of the anatomical structures of the neck when performing any surgical manipulation in this area.

    Directory of Open Access Journals (Sweden)

    Konstantinos Stamatiou

    2014-01-01

    Full Text Available Urethral stricture is a common condition that can lead to serious complications such as urinary infections and renal insufficiency secondary to urinary retention. Treatment options include catheterization, urethroplasty, endoscopic internal urethrotomy, and dilation. Optical internal urethrotomy offers faster recovery, minimal scarring, and less risk of infection, although recurrence is possible. However, technical difficulties associated with poor visualization of the stenosis or of the urethral lumen may increase procedural time and substantially increase the failure rates of internal urethrotomy. In this report we describe a technique for urethral catheterization via a suprapubic, percutaneous approach through the urinary bladder in order to facilitate endoscopic internal urethrotomy.

    Continent urinary diversions are gaining wide acceptance as alternatives to the ideal conduit following cystectomy. Clean intermittent catheterization of the pouch at regular intervals obviates the inconvenience of an external stomal appliance. A variety of surgical techniques have been described for continent pouches. These use the small bowel alone or a combination of the cecum and the terminal ileum. The optimum pouch protects upper tracts by preventing reflux, provides urinary continence, and has sufficient capacity to require infrequent catheterization. Simplified construction techniques for the common pouches are graphically presented, and methods are suggested for identification and study of continent diversions

    Insulin secretion was investigated in acutely anaesthetized and chronically catheterized sows and their fetuses during late gestation. In the conscious animals, the mean fetal concentration of plasma insulin was 8.4 +/- 1.5 microunits/ml which was significantly less than the corresponding maternal value of 33.9 +/- 6.5 microunits/ml (n = 12, P less than 0.01). The plasma concentrations of insulin and glucose in the new-born piglets from these litters were not significantly different from the values observed in utero. The plasma concentration of insulin in the anaesthetized fetuses was significantly less than that in the chronically catheterized piglets over the same range of glucose levels. In the chronically catheterized animals, both fetal and maternal levels of insulin rose with increasing concentrations of plasma glucose while under acute conditions there was no correlation between the endogenous concentrations of insulin and glucose in either the fetuses or their mothers. Infusion of exogenous glucose (0.5 g as a 50% solution in 0.9% NaCl) stimulated the release of insulin in all the chronically catheterized fetuses studied but rarely increased the concentration of insulin in the anaesthetized fetusus. The present findings show that anaesthesia and surgery depress pancreatic beta cell function in the pig, particularly in the fetus. PMID:7043523

    Acute urinary retention secondary to vasculitic penile swelling in children is extremely rare. Henoch-Schönlein purpura is a self-limiting IgA-mediated cutaneous vasculitis, which can cause soft tissue edema. Acute urinary retention requires urgent intervention to prevent obstructive uropathy. Suprapubic catheterization provides an effective management strategy in the emergency setting. PMID:27014447

    PurposeCystic echinococcosis (CE) in the spleen is a rare disease even in endemic regions. The aim of this study was to examine the efficacy of percutaneous treatment for splenic CE.Materials and MethodsTwelve patients (four men, eight women) with splenic CE were included in this study. For percutaneous treatment, CE1 and CE3A splenic hydatid cysts were treated with either the PAIR (puncture, aspiration, injection, respiration) technique or the catheterization technique.ResultsEight of the hydatid cysts were treated with the PAIR technique and four were treated with catheterization. The volume of all cysts decreased significantly during the follow-up period. No complication occurred in seven of 12 patients. Abscess developed in four patients. Two patients underwent splenectomy due to cavity infection developed after percutaneous treatment, while the spleen was preserved in 10 of 12 patients. Total hospital stay was between 1 and 18 days. Hospital stay was longer and the rate of infection was higher in the catheterization group. Follow-up period was 5–117 months (mean, 44.8 months), with no recurrence observed.ConclusionThe advantages of the percutaneous treatment are its minimal invasive nature, short hospitalization duration, and its ability to preserve splenic tissue and function. As the catheterization technique is associated with higher abscess risk, we suggest that the PAIR procedure should be the first percutaneous treatment option for splenic CE.

  15. MRI in postoperative assessment of univentricular heart disease: correlation with echocardiography and angiography

    International Nuclear Information System (INIS)

    Purpose: To determine the value of MRI in the postoperativ evaluation of a singular ventricle compared to echocardiography and cardiac catheterization. Materials and methods: Thirty-one patients (range: 6 months to 30 years) with a functional single ventricle following palliative corrective operations. Five patients had a Blalock-Taussig-Shunt, 8 patients a Glenn-Anastomosis and 18 a cavopulmonary shunt (6 with classic Fontan-Circulation, 12 with modified cavopulmonary anastomosis). The results in terms of postoperative morphologic changes were compared to percutaneous echocardiography (31/31) and cardiac catheterization (6/31). Results: Echocardiography, which was performed on all patients, could not visualize the entire length of the tunnel, the Glenn-Anastomosis or the central pulmonary arteries in 70% of the patients due to an inadequate acoustic window. MRI was able to show the entire tunnel in 11/12 patients and the central pulmonary arteries in 30/31 patients. The exact anatomy was seen in all 6 patients undergoing cardiac catheterization. Concusion: MRI is useful in the postoperative evaluation of a functionally single ventricle. It is superior to echocardiography. Cardiac catheterization should be reserved for patients with inconclusive MRI findings. (orig.)

    Splenic arteriovenous fistula is a rare but curable cause of portal hypertension. This report describes a patient with such a disorder, presenting with bleeding esophageal varices and ascites. It emphasises the importance of performing selective catheterization of the celiac and superior mesenteric artery in all patients with signs of portal hypertension without evidence of chronic liver disease. Etiopathology and management are discussed.
