    Abstract:
    PURPOSE: To retrospectively review our experience with visceral artery aneurysms (VAAs) treated with percutaneous coil embolization techniques. METHODS: Patient records were retrospectively reviewed between 1988 and 1998 for VAA cases treated with catheter-based techniques. Nine patients (5 women; mean age 64 +/- 11 years) with 12 (8 false and 4 true) VAAs were identified. The majority (67%) of these patients presented with symptoms of aneurysm rupture. The etiology of the aneurysm was iatrogenic in 4, pancreatitis in 4, and idiopathic in 4. Ten cases involved the hepatic artery; the other 2 aneurysmal arteries were the middle colic and the gastroduodenal. Selective and superselective catheter techniques were used to obtain access to the VAA. A variety of microcoils were delivered to entirely fill saccular aneurysms, whereas fusiform aneurysms were thrombosed by occluding the inflow and outflow vessels. RESULTS: Aneurysm exclusion was achieved in 9 (75%) of the 12 cases. The 3 technical failures resulted from the inability to cannulate the aneurysm neck. Coil embolization of the neck of the aneurysm sac did not result in occlusion of the native vessel, with a single exception. No procedure-related complications or deaths were noted. All patients remained symptom free during a mean follow-up of 46.0 +/- 29.6 months. CONCLUSIONS: Percutaneous transcatheter coil embolotherapy is an effective alternative to open surgery for the management of VAAs. This therapy may decrease the morbidity and mortality associated with an open surgical procedure in patients with ruptured aneurysms and pseudoaneurysms, selectively thrombosing the aneurysm while preserving flow in the native vessel.
