Postnephrectomy pseudoaneurysm with arteriovenous fistula

Sonography detected a paraaortic pulsatile tubular mass in a patient 10 years after "stump" nephrectomy, which was subsequently confirmed as a renal artery-renal vein fistula by computed tomography, angiography, and laparotomy.     

Traumatic basilar pseudoaneurysm with a basilar-cavernous arteriovenous fistula

A traumatic pseudoaneurysm of the basilar artery with a basilar-cavernous sinus arteriovenous fistula was diagnosed in a 12-year-old girl using CT, MRI and angiography. It was successfully treated by coil embolisation. We speculate on the mode of formation of this rare traumatic lesion. Received: 4 July 2000 Accepted: 20 September 2000 Published online:     

Postnephrectomy arteriovenous fistula of the renal pedicle treated with detachable balloons: A case report

A case of postnephrectomy arteriovenous fistula of the right renal pedicle is reported here. The diagnosis was confirmed by angiography, and successful treatment was achieved using detachable balloon.     

Traumatic inferior gluteal artery pseudoaneurysm and arteriovenous fistula managed with emergency transcatheter embolization

We present a case of blunt trauma to the buttock resulting in an inferior gluteal artery pseudoaneurysm and arteriovenous fistula. The characteristic diagnostic features on CT angiography and digital subtraction angiography (DSA), along with the emergency percutaneous management of this traumatic vascular injury, are described. A review of the literature demonstrates inferior gluteal artery pseudoaneurysm is a rare condition, while successful treatment with glue embolization is previously unreported.     

Endovascular repair of a large post-traumatic calf pseudoaneurysm and arteriovenous fistula

Endovascular techniques are being increasingly used as the definitive method of repair for various traumatic vascular injuries. This case report describes the use of transcatheter embolization and direct percutaneous thrombin injection used in the definitive treatment of a lower extremity posttraumatic pseudoaneurysm and arteriovenous fistula.

Liver abscess associated with hepatic artery pseudoaneurysm with arteriovenous fistula: imaging and interventional management

Hepatic artery pseudoaneurysm is an infrequently encountered entity that is usually seen secondary to trauma or surgical procedures. The clinical presentation is often due to complications such as massive intrahepatic or intraperitoneal bleeding as a result of rupture of the pseudoaneurysm into the biliary tree or peritoneal cavity, respectively. Hepatic artery pseudoaneurysm, associated with a liver abscess, has very rarely been described in the literature. We present the imaging features of a case of liver abscess associated with a hepatic artery pseudoaneurysm and complicated by rupture and formation of an arteriovenous fistula. The case was successfully managed by percutaneous endovascular embolization. The association between a hepatic artery pseudoaneurysm and a liver abscess must not be overlooked, bearing in mind the potentially fatal associated complications which can be averted or treated by timely intervention.     

Balloon-assisted,ultrasound-guided percutaneous real-time thrombin injection,for the arteriovenous fistula pseudoaneurysm treatment

A pseudoaneurysm or false aneurysm is the consequence of a persistent blood leak caused generally by iatrogenic rupture of a vessel wall. The blood leak creates a new cavity delimited by surrounding tissues and allows blood flow to remain in continuity between this cavity and the vessel. In hemodialysis fistula, pseudoaneurysm generally results from repeated puncturing of the vein at the same site, leading to a bulging anatomical defect in the vein. Over the past few years, interventional radiological treatment has evolved and taken the place of surgery, with different kinds of percutaneous and endovascular treatment methods in pseudoaneurysm management. We reported a case report of successful treatment of arteriovenous fistula pseudoaneurysm with no-measurable neck. We performed ultrasound-guided percutaneous direct thrombin injection while an inflated balloon transiently obstructed flow out of the pseudoaneurysm, in order prevent non-target embolization.     

股静脉置管行血液透析致动静脉瘘合并假性动脉瘤的护理

慢性肾功能衰竭的患者在开始血液透析前,常行股静脉置管建立临时通路,同时准备永久性的血管通路。股静脉置管不仅可以减少患者反复穿刺所带来的痛苦,还可以为血液透析提供较好的血流量,并等待永久性血管通路的建立。     

Percutaneous thrombin injection of a femoral artery pseudoaneurysm with simultaneous venous balloon occlusion of a communicating arteriovenous fistula

An 82-year-old woman developed acute occlusion of her right coronary artery. She underwent percutaneous coronary stent placement and aortic balloon pump installation. In the postprocedural period, she developed a common femoral artery pseudoaneurysm (PSA) that communicated with the common femoral vein via an arteriovenous fistula (AVF). After unsuccessful ultrasound-guided compression, ultrasound-guided thrombin injection of the PSA was performed, with simultaneous balloon occlusion of the common femoral vein at the level of the AVF. There was complete thrombosis of the PSA and AVF.     

硬脑膜动静脉瘘

硬脑膜动静脉瘘(dural arteriovenous fistula,DAVF)是指动静脉交通在硬脑膜及其附属物大脑镰和小脑幕的一类血管性疾病,也称为硬脑膜动静脉畸形(DAVM).该病约占颅内血管畸形的10%～15%.     

Posterior cranial fossa arteriovenous fistula with presenting as caroticocavernous fistula

We report cases of posterior cranial fossa arteriovenous fistula (AVF) with presenting with exophthalmos, chemosis and tinnitus in 26- and 66-year-old men. The final diagnoses was vertebral artery AVF and AVF of the marginal sinus, respectively. The dominant venous drainage was the cause of the unusual presentation: both drained from the jugular bulb or marginal sinus, via the inferior petrosal and cavernous sinuses and superior ophthalmic vein. We used endovascular techniques, with coils and liquid adhesives to occlude the fistulae, with resolution of the symptoms and signs. Received: 9 December 1999 Accepted: 27 March 2000     

Rendu-Osler-Weber syndrome presenting with pulmonary arteriovenous fistula

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

Lumbar artery pseudoaneurysm and arteriovenous fistula as a complication of laparoscopic splenectomy: treatment by transcatheter embolization

Iatrogenic injury of a lumbar artery is very rare and mostly causes retroperitoneal hemorrhage. We report a case of a lumbar artery pseudoaneurysm and a concomitant arteriovenous fistula complicating laparoscopic splenectomy and provoking renal colic-like flank pain due to mass effect on the left ureter. Definitive treatment of both vascular lesions was obtained after percutaneous transcatheter embolization of several lumbar arteries. Control computed tomography scan 3 months after embolization showed almost complete resorption of the retroperitoneal hematoma.     

Iatrogenic femoral arteriovenous fistula

Twelve iatrogenic femoral arteriovenous fistulas are reported, 11 of which arose from the superficial or deep femoral arteries. All but two occurred in association with cardiac angiographic procedures. It appears that the femoral crease was used as a landmark to establish the cutaneous entry point for vascular puncture and resulted in an excessively distal puncture site. The femoral crease is an unreliable landmark in many patients. This complication may be minimized by using physical examination to identify the level of the inguinal ligament or fluoroscopy to localize the distal half of the femoral head.
