11/141. Iatrogenic left ventricular-right atrial fistula following mitral valve replacement and tricuspid annuloplasty: diagnosis by transthoracic and transesophageal echocardiography.Acquired left ventricle-to-right atrium communications are a known complication of valvular heart surgery. Previous reports have described the clinical features and diagnosis using cardiac catheterization. We report two cases of acquired left ventricle-to-right atrium fistula following mitral valve replacement. Particular emphasis is placed on the diagnosis using transthoracic and transesophageal echocardiography, obviating the need for cardiac catheterization before repair.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
12/141. Vaginal pedicled flap for closure of vesicovaginal fistula.A 22-year-old woman presented with chronic urinary tract infections and was found to have an ectopic ureter. Repair involved ligation of the distal ectopic ureter via a vaginal approach. She developed an iatrogenic vesicovaginal fistula which was repaired with a vaginal pedicled flap.- - - - - - - - - - ranking = 1.0017692378924keywords = fistula, urinary (Clic here for more details about this article) |
13/141. vertebral artery pseudoaneurysm complicating posterior C1-2 transarticular screw fixation: case report.BACKGROUND: vertebral artery injury during posterior C1-2 transarticular screw fixation occurs in approximately 3% of patients and may remain asymptomatic or result in arteriovenous fistulae, occlusion, narrowing, or dissection of the vertebral artery, and lead to transient ischemic attacks, stroke, or death. CASE DESCRIPTION: This is the first report of a pseudoaneurysm resulting from damage to the vertebral artery during the procedure. This 31-year-old male underwent posterior C1-2 transarticular screw fixation for unstable os odontoideum. Injury to the left vertebral artery occurred while the hole for the left screw was being drilled. Temporary control of bleeding with local pressure was followed by immediate postoperative angiography that revealed a left vertebral artery pseudoaneurysm. Although the patient remained asymptomatic, therapeutic anticoagulation was instituted 6 hours postoperatively. Increasing size of the pseudoaneurysm was noted on routine follow-up angiography 4 weeks later. Endovascular occlusion of the pseudoaneurysm and left vertebral artery, with preservation of vertebrobasilar flow through the right vertebral artery, was accomplished without neurological consequence. CONCLUSIONS: vertebral artery pseudoaneurysm complicating posterior C1-2 transarticular screw fixation may be effectively treated with endovascular approaches.- - - - - - - - - - ranking = 0.2keywords = fistula (Clic here for more details about this article) |
14/141. Percutaneous repair of an iatrogenic laceration of the left bile duct with a covered stent.The presence of biliary leaks after liver resections is not an unusual problem, especially after extended hepatectomies. The usual treatment of choice for biliary duct injuries is to decompress the biliary system with draining catheters. Persistent biliary fistulas are nevertheless a challenging problem when endoscopic or percutaneous approaches fail to achieve occlusion of the bile leakage. The authors report a bile duct injury after a right lobe hepatectomy treated percutaneously with placement of a covered stent. After 6 months, the patient was tube-free and without any episode of cholangitis or bile duct dilation. Longer follow-up will clarify the future role of this kind of device in biliary system lacerations.- - - - - - - - - - ranking = 0.2keywords = fistula (Clic here for more details about this article) |
15/141. An iatrogenic coronary arteriovenous fistula causing a steal phenomenon: an intracoronary Doppler study.We present the case of a 67-year-old man in whom a guidewire broke at rotablation of the right coronary artery, creating an iatrogenic aneurysmal arteriovenous fistula to the coronary sinus. Successful Doppler wire-guided fistula occlusion by percutaneous coil embolization lead to normalization of coronary blood flow and relief of the patient's symptoms. myocardial ischemia in this patient may have been due to a steal phenomenon caused by coronary artery fistulae, as suggested by blood flow velocity data obtained before and after fistula occlusion.- - - - - - - - - - ranking = 1.6keywords = fistula (Clic here for more details about this article) |
16/141. Endovascular stent-graft treatment of an iatrogenic vertebral arteriovenous fistula.We present a high-flow vertebral arteriovenous fistula caused by percutaneous catheterisation of the internal jugular vein. Endovascular transarterial treatment with a self-expanding covered stent was used to close the fistula successfully with preservation of the parent artery.- - - - - - - - - - ranking = 1.2keywords = fistula (Clic here for more details about this article) |
17/141. A rare complication of laparoscopic surgery: iatrogenic arteriovenous fistula with high-output cardiac failure.SUMMARY: The authors report a 19-year-old man with cardiomegaly and high-output cardiac failure resulting from a hemodynamically significant arteriovenous fistula that was diagnosed 18 months after laparoscopic surgery for an inguinal hernia. The diagnosis was established on clinical examination and by ultrasonography and was confirmed by cardiac catheterization and angiography. The fistula was closed surgically by direct venous suture and reconstruction of the iliac artery with a polytetrafluoroethylene patch. The surgical repair achieved complete closure of the fistula with rapid normalization of cardiac size and function within 8 days.- - - - - - - - - - ranking = 1.4keywords = fistula (Clic here for more details about this article) |
18/141. Ileal conduit perforation-iatrogenic injury and conservative management.The ileal conduit was popularized by Bricker in the 1950s. Since then, surveillance of the upper urinary tract has been accomplished with intravenous urography, ultrasonography, or loopography. Loopography is used as an imaging modality at our institution because of its safety and avoidance of intravenous contrast. We report the first case of an iatrogenic rupture of an ileal conduit during loopography.- - - - - - - - - - ranking = 0.0017692378923762keywords = urinary (Clic here for more details about this article) |
19/141. Conservative treatment of iatrogenic urinary fistulas: the value of cyanoacrylic glue.Once previously attempted conservative maneuvers have failed, iatrogenic persistent urinary fistulas usually require difficult repeated operations. We describe 3 patients in whom cyanoacrylic glue was used to repair endoscopically persistent urinary fistulas occurring after major pelvic surgery. At a mean follow-up of 21 months, all patients were free of urinary leakage and had no evidence of recurrent urinary fistulas. This approach may represent a safe and effective way to repair postoperative urinary fistulas.- - - - - - - - - - ranking = 1.6159231410314keywords = fistula, urinary (Clic here for more details about this article) |
20/141. Closure of an iatrogenic aortocoronary arteriovenous fistula: transcatheter balloon embolization following failed coil embolization and salvage of coils that migrated into the coronary venous system.We report a 50-year-old patient with successful percutaneous closure of a large inadvertent surgical aortocoronary arteriovenous fistula (shunt flow: 1.8 L/min). With initial embolization of multiple coils, no lasting occlusion of the large fistula could be achieved. Above that, two coils migrated into the coronary venous system. Following rescue of the migrated coils through a retrograde coronary sinus approach, the fistula was occluded using a detachable balloon. Follow-up angiograms confirmed successful closure of the fistula. In contrast to coil embolization, use of a detachable balloon seems to be the appropriate technique for percutaneous closure of such fistulas.- - - - - - - - - - ranking = 1.8keywords = fistula (Clic here for more details about this article) |
