Use of extraperitoneal iliac artery endarterectomy in the endovascular era.
Although iliac artery (IA) endarterectomy has largely been replaced by bypass and endovascular options, open endarterectomy continues to play an important role in selected patterns of occlusive disease. The objective of this report is to present a contemporary clinical series of patients having undergone IA endarterectomy. Specifically, we define patterns of disease amenable to open endarterectomy and provide an updated technical note of this procedure. A retrospective study on 23 patients with IA occlusions unsuitable for radiologic intervention (TransAtlantic Inter-Societal Consensus [TASC] C and D lesions) underwent extraperitoneal IA endarterectomy. Twenty-five primary IA endarterectomies were performed. Of these, five required more extensive endarterectomy, three of the distal aorta and two of the contralateral IA. Sixteen of the 25 endarterectomies required common femoral artery endarterectomy and 6 required iliofemoral bypass. The average follow-up was 26 months. Procedure-related mortality occurred in one patient (4.3%). Within 4 months, one patient underwent an aortofemoral bypass and two patients required major amputation. Primary patency rates were 96% at 3 months and 88% at 1, 2, and 3 years. This series shows that in selected patterns of aortoiliac occlusive disease, endarterectomy remains an important alternative to consider.
