Abstract:
Objective To report the preliminary results of drug eluting stents (DES) in infrapopliteal bifurcation lesions after failed angioplasty.Methods From April 2011 to December 2013, 21 patients with critical limb ischemia and infrapopliteal atherosclerotic disease underwent DES placement in tibial bifurcation using 4 techniques: balloon and stent (single stent), T-shape double-stent, Crush double-stent and Culotte double-stent.Clinical and angiographic end points included: Amputation-free survival, target lesion revascularization (TLR)-free survival, target vessel revascularization (TVR)-free survival.Angiographic primary and secondary patency of DES, 2-vessel primary patency (2VPP), and 1-vessel primary patency (1VPP).Results Technical success was achieved in all patients (100％) without major intraoperative complications.ABI increased from 0.23 ± 0.07 to 0.67 ± 0.24 (P ＜ 0.05) after 1 week.The mean follow-up intervals were 23 ± 7 months;amputation-free survival, TLR-free survival and TVR-free survival were 100％, 90.5％ and 79.1％, respectively, at 1 year.8 patients underwent angiography reevaluation.The angiographic primary and secondary patency of DES were 62.5％, 87.5％, respectively.The primary patency of 2VVP and 1VVP were 28.6％, 57.1％, respectively at 1 year.Conclusions Bifurcation stenting techniques utilized in coronary arteries can be used in the infrapopliteal arteries.Although provisional stenting in the origin of tibial bifurcation cannot inhibit restenosis in distal lesions treated with balloon angioplasty, clinical outcomes and limb salvage rates are acceptable for these techniques.
