BackgroundThe endovascular approach has been widely used for aortoiliac occlusive disease (AIOD), especially for aortic bifurcation and iliac artery Trans-Atlantic Inter-Society Consensus II (TASC-II) A and B lesions. However, the outcomes of self-expanding covered stents (SECSs) for extensive aortoiliac lesion remain unclear. This study aimed to assess the short-term patency of kissing covered stents for the revascularization of aortoiliac TASC-II C and D diseases.MethodsThirty-three patients with TASC-II C and D lesions of AIOD were treated with kissing covered stents. All patients were reviewed under a standard institutional review board protocol. Demographic variables, lesion location and characteristics, stenting configuration, and patency were analyzed.ResultsThirty-one male and 2 female patients with a mean age of 65.1 ± 10.7 years underwent aortoiliac bifurcation reconstruction with kissing SECSs. Eight patients had TASC-II C lesions, and 25 patients had TASC-II D lesions. Among them, 8 patients had total infrarenal aortoiliac occlusion, of which 5 had juxtarenal aortoiliac lesions. The mean lesion length was 11.6 ± 2.1 cm. Mean diameters of aorta and common iliac artery were 18.3 ± 2.1 and 10.7 ± 1.5 mm, respectively. Among them, the abutting stent configuration was used in 11 patients with short or focal ostial lesions, whereas the crossing stent configuration was used in 22 patients with longer lesions extending into the distal aorta. The mean follow-up was 24.5 ± 7.8 months, the follow-up rate was 93.9% (31 of 33), and 29 patients had follow-up longer than 12 months. Primary patency rate at 12 months was 96.5%, and secondary patency rate was 100%.ConclusionsThe use of kissing SECSs for the revascularization of extensive AIOD is safe and effective. The short-term primary patency rates of endovascular treatment of TASC-II C and D lesions were favorable.Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.
