Abstract

PURPOSE: To investigate the clinical features and treatment results of the iliac artery aneurysms (IAAs). METHOD: From June 1996 to December 2005, 28 patients (mean age, 64.3+/-14.4 year, all male) underwent open surgical (n=24) or endovascular (n=4) treatment for 41 IAAs at Samsung Medical Center and Kyung-Pook National University Hospital. The medical records and arteriographic findings were retrospectively reviewed. RESULT: The mean diameter of IAAs was 4.1 cm, 71% of patients were symptomatic and the most common etiology of aneurysm was nonspecific (89%) followed by Behcet's vasculitis in 3 patients (11%). IAAs were located at the common iliac in 20 (71.4%), the internal iliac in 4 (14.3%), and the external iliac artery in 2 patients (7.2%). On the arteriograms, IAAs were classified into 2 categories: the isolated IAAs (category I, n=18) and IAAs coexistent with small AAAs (Category II, n=10). After treatments, 2 operative mortalities occurred in ruptured IAA patients. Upon retrospective review of the arteriograms and clinical features, 5 patients (18%) can be candidates for isolated iliac stent graft while 13 patients (46%) for aortic stent graft. CONCLUSION: The IAAs often presented with symptoms due to aneurysm rupture or surrounding organ compression. By classifying IAAs according to their location and clinical features, less than 20% of IAAs can be candidates for iliac stent graft.
