Abstract

Although endovascular therapy (EVT) has been widely used for iliac lesions due to acceptable patency with stenting, EVT has not been established as primary treatment for aortic occlusion, partly because of uncertainty regarding long-term results. The purpose of this study was to investigate outcomes following EVT with stenting for chronic aortic occlusion. This study was a single-center retrospective analysis of a prospectively maintained database. Between September 2005 and May 2012, twenty-four lesions from 25 patients with a clinical diagnosis of chronic aortic occlusion (mean age, 71 years; 80 % male) were treated with EVT with stenting. Kaplan-Meier estimators were used to determine the patency rates according to Society for Vascular Surgery criteria. In results, lesion type was Trans Atlantic Inter-Society Consensus D in all patients. Mean lesion length was 145 mm. Initial success rate and procedural complication rate were 96 % (24/25) and 8 % (2/25), respectively. At 36 months, primary and secondary patency rates were 76 and 94 %, respectively. Restenosis was observed in 5 patients, all of whom underwent reintervention (four successful, one failure and intensity of medical treatment). EVT can be safely done in patients with chronic aortic occlusion. Procedural morbidity and mid-term durability were comparable to those of bypass surgery up to 3 years.
