PURPOSE: To assess efficacy of transcatheter embolization of periprost
hetic leaks from aortic stentgrafts. MATERIALS AND METHODS: Eight pati
ents with a long-standing (3-13 months) perigraft leak after stentgraf
t implantation underwent transcatheter embolization. Leakage was demon
strated 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 necessar
y in one patient to complete occlusion of the aneurysm. No further ane
urysmal growth was detected during 4-9 months follow-up. Right leg par
esis was observed in one patient immediately after the procedure, but
symptoms disappeared completely after 8 days. Another patient had a mi
nor sensory deficit in the region of the right crural nerve. CONCLUSIO
N: Transcatheter embolization of perigraft leaks appears to be an effe
ctive technique to achieve aneurysmal thrombosis.
