Endovascular stent graft repair of iatrogenic popliteal artery injuries--a report of 2 cases.

Popliteal artery injury during total knee replacement (TKR) is rare. We report 2 cases of post-TKR popliteal artery occlusions treated endovascularly with Viabahn stent grafts. Long-term duplex follow-up and secondary re-intervention may be necessary.

The diagnosis and endovascular management of superior mesenteric artery (SMA) branch pseudoaneurysms after appendicectomy.

Pseudoaneurysms arising from the visceral arteries are rare. We present 2 patients who developed pseudoaneurysms arising from branches of the superior mesenteric artery (SMA) following laparoscopic appendicectomy. Both cases were successfully treated by endovascular embolization.

Initial experience with a new fenestrated stent graft.

Objectives: The Anaconda fenestrated stent graft (Vascutek, Inchinnan, United Kingdom) is a new device that can easily be repositioned during deployment. This study evaluated its feasibility for treating abdominal aortic aneurysms with inadequate infrarenal sealing zones.

Methods: Patients undergoing stent graft placement at two institutions in the United Kingdom were recruited.

Endovascular management of delayed complete graft thrombosis after endovascular aneurysm repair.

Graft thrombosis rates after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms vary widely in published series. When thrombosis does occur, it usually involves a single limb and occurs within 3 months of stent-graft insertion. If the entire endoprosthesis is thrombosed, treatment may be challenging because femoro-femoral crossover graft insertion is not an option and a greater volume of thrombus is present, thus making thrombolysis more difficult.

Endovascular repair of a primary iliac-cecal fistula presenting with gastrointestinal hemorrhage.

We report a case of an arterio-enteric fistula between an external iliac artery aneurysm and otherwise healthy cecum, presenting with torrential hemorrhage per rectum in an 85-year-old patient. Whilst fistulization to the aorta and common iliac arteries has been reported, to our knowledge no previous cases of primary fistulization between an external iliac aneurysm and normal cecum have been. Successful endovascular exclusion of the aneurysm was undertaken with a Wallgraft covered stent and the patient remains well at 1 year.

Endovascular repair of a pseudoaneurysm of the abdominal aorta secondary to translumbar aortography.

This report describes an incidental finding of a pseudoaneurysm of the abdominal aorta on a computed tomography (CT) renal angiogram during investigation of chronic renal failure in a 73-year-old man. The patient had undergone a translumbar aortogram 20 years previously. An increase in the size of the aneurysm by 7 mm over 6 months prompted treatment and the aneurysm underwent successful endovascular repair with a custom-made stent-graft.
