Comparison of results between kissing stent and aortic bifurcated bypass in aortoiliac occlusive disease.

Abstract

OBJECTIVE\nKissing stent (KS) technique has been used as an alternative to aortic bifurcated bypass surgery (ABBS) for aortoiliac occlusive disease (AIOD). We aimed to compare the results of ABBS and KS in AIOD.\n\n\nMETHODS\nMedical records of patients treated with ABBS and KS between March 2011 and December 2016 in a single center were retrospectively analyzed. The patients characteristics and clinical outcomes were evaluated.\n\n\nRESULTS\nPatients who underwent ABBS had a more common history of smoking (P\xa0=\xa00.04) and lower body mass index (P\xa0=\xa00.02). A significant difference was observed between the two groups in terms of the TransAtlantic Inter-Society Consensus II classification (P\xa0<\xa00.01). A significant difference was observed between the two groups of improvement in postoperative mean ankle-brachial indexes (ABI) (ABBS: 0.57\xa0±\xa00.24 vs KS: 0.41\xa0±\xa00.18, P\xa0=\xa00.01). A significant difference was observed between the combined treatments of the two groups (P\xa0<\xa00.01). Primary patency rates of the ABBS and KS groups at 1, 2, and 3 years were 90.1% and 100%, 82.6% and 90.6%, and 82.6% and 90.6%, respectively (P\xa0=\xa00.637). Primary assisted patency rates of the ABBS and KS groups at 1, 2, and 3 years were 90.1% and 100%, 82.6% and 95.7%, and 82.6% and 95.7%, respectively (P\xa0=\xa00.110). Secondary patency rates of the ABBS and KS groups at 1, 2, and 3 years were 93.8% and 100%, 93.8% and 95.7%, and 93.8% and 95.7%, respectively (P\xa0=\xa00.512).\n\n\nCONCLUSION\nABBS in AIOD remains an important revascularization option whenever endovascular treatment is not feasible.
