ABSTRACT
BACKGROUND:To explore the methods for secondary limb revascularization after endovascular repair is one of the most urgent research topics. OBJECTIVE:To investigate the biological mechanism about the transplantation of autologous peripheral blood stem cel s to lead and perfect the effect of ischemic tissue for secondary revascularization. METHODS:Forty-two patients with critical low limb ischemia were selected and treated with endovascular repair as first revascularization and transplantation of autologous peripheral blood stem cel s as secondary revascularization. The secondary revascularization was carried out at 3 months after the first blood flow remodeling. The patients receiving secondary revascularization were fol owed for 4 years. RESULTS AND CONCLUSION:After transplantation of autologous peripheral blood stem cel s, the patients complained that the rest pain of the lower leg was relieved obviously and intermittent claudication distance was significantly lengthened. Limb salvage rate was 100%. Skin temperature index was 1.6±0.3, transcutaneous oxygen pressure was (5.00±1.26) kPa, ankle-brachium index was 0.9±0.2, photoplethysmograpy index was 0.8±0.1, saturation of blood oxygen was (79.4±20.4)%, and digital subtraction angiography score was (1.3±0.2) points. After transplantation, local blood flow indicators of the low limbs were positively correlated to local symptom indicators of the limbs (0.6
