Long - Term Results of Iliac Intervention

avorable results have been obtained with endovascular treatment (EVT) for iliac artery lesions, compared with lesions of the femoral artery, even in the follow-up period.1–5 The therapeutic strategy for peripheral arterial disease (PAD) is generally selected according to the lesion type based on the morphological stratification of the TransAtlantic Inter-Society Consensus (TASC-I).6 In 2007, this classification was revised to define new lesion types and the adaptive range of lesions indicated for EVT was expanded in the Inter-Society Consensus for the Management of Peripheral Arterial Disease (TASC-II) classification for the aortoiliac artery and femoropopliteal artery. 7 There have been few reports on the long-term patency of treatment of Type C and Type D lesions as defined in the TASC-I guidelines, including occlusion lesions over a wide range, and there are no detailed reports of follow-up evaluation of EVT performed for lesions based on the TASC-II classification. Therefore, in this study, we analyzed the initial and long-term results and factors associated with restenosis after EVT for iliac artery lesions categorized by the TASC-II classification.
