METHODS:We report an unusual case of hemoperitoneum caused by rupture of cystic artery pseudoaneurysm,and also outline the approach to its management through surgical and radiological methods. RESULTS:In our patient,the pseudoanurysm was initially treated with percutaneous thrombin injection.However this method of treatment failed after initial success.The pseudoanurysm was finally obliterated successfully using microcoil embolization. CONCLUSIONS:The mainstay of treatment of cystic artery pseudoaneurysm is cholecystectomy and ligation of the aneurysm.Recent publications showed success in using microcoil embolisation.In this case we also outline the use of percutaneous thrombin injection as a definitive treatment method and discuss its success or failure as a new method of treatment.展开更多

We report on a case of a 33-year-old woman with a combined arteriovenous fistula (AVF) and venous popliteal aneurysm that developed 6 months after arthroscopic anterior cruciate ligament reconstruction. At clinical exam the patient presented with left popliteal and calf pain, a tender pulsatile mass posterior to her left knee, popliteal bruit and a thrill at the popliteal fossa. CT scan showed an AVF arising from the left popliteal artery. An aneurysm was seen to fill at the same time as the popliteal vein. Findings at open surgical revision included AVF between the tibioperoneal trunk and the popliteal vein and a venous popliteal aneurysm at the level of the arteriovenous communication. The aneurysm and fistula were repaired. The patient had an uneventful follow up with complete recovery. We also report an endovascular treatment of a iatrogenic arterio-venous fistula.展开更多
