Abstract

PURPOSE: To assess efficacy of transcatheter embolization of periprosthetic leaks from aortic stentgrafts. MATERIALS AND METHODS: Eight patients with a long-standing (3-13 months) perigraft leak after stent graft implantation underwent transcatheter embolization. Leakage was demonstrated at helical computed tomography (CT). Angiography was performed for evaluation of outflow vessels and transcatheter embolization. All patients underwent helical CT follow-up after the procedure and every 3 months. RESULTS: Embolization was successful in seven patients and resulted in aneurysmal sac thrombosis. A second procedure was necessary in one patient to complete occlusion of the aneurysm. No further aneurysmal growth was detected during 4-9 months follow-up. Right leg paresis was observed in one patient immediately after the procedure, but symptoms disappeared completely after 8 days. Another patient had a minor sensory deficit in the region of the right crural nerve. CONCLUSION: Transcatheter embolization of perigraft leaks appears to be an effective technique to achieve aneurysmal thrombosis.
