Objective To evaluate the efficacy and safety of endovascular implantation of bare-metal stent (BMS) and endovascular implantation of drug-eluting stent (DES) in treatment of infrapopliteal arterial occlusive disease by using Meta-analysis. Methods Randomized controlled trial about endovascular implantation of BMS and endovascular implantation of DES in treatment of infrapopliteal arterial occlusive disease were searched in domestic and international databases, literature screening in accordance with inclusion criteria and exclusion criteria was taken firstly, and then quality assessment was performed. Comparison of 1-year restenosis rate, 1-year patency rate, incidence of limb salvage, mortality, and 1-year target lesion revascularization rate after operation between BMS group and DES group were performed by using RevMan 5.2 software for Meta-analysis. Results Six literatures included 572 cases who suffered from infrapopliteal arterial occlusive disease were included at all, including 302 cases in DES group and 270 cases in BMS group. The results of Meta-analysis showed that, compared with BMS group, 1-year patency rate after operation in DES group was higher (OR=1.64, 95% CI:1.35-1.98, P < 0.000 1), but 1-year restenosis rate (OR=0.19, 95% CI:0.12-0.30, P < 0.000 1) and 1-year target lesion revascularization rate after operation (OR=0.09, 95% CI:0.02-0.32, P=0.000 2) were both lower. There were no significance difference between the BMS group and DES group on incidence of postoperative limb salvage (OR=1.29, 95% CI:0.58-2.86, P=0.530 0) and postoperative mortality (OR=0.98, 95% CI:0.58-1.65, P=0.940 0). Conclusions Compared with endovascular implantation of BMS, endovascular implantation of DES can increase the 1-year patency rate and reduce 1-year restenosis rate or 1-year target lesion revascularization rate after operation for infrapopliteal arterial occlusive disease.
