摘　　要：目的回顾性分析股腘动脉TASCII C、D型病变支架治疗通畅率及再狭窄影响因素。方法纳入在我院行股腘动脉支架术治疗的TASCII C、D型病变患者178例。通过彩色多普勒超声（CDU）观察支架术后血流动力学变化特征,统计术后3、6、12、24个月的支架通畅率,分析支架术后再狭窄影响因素。结果本研究入组患者178例（420枚支架）,平均支架总长度（24.93±10.83）cm。随访时间3~24个月,术后3、6、12、24个月的总体通畅率分别为92.9%、69.6%、39.2%和28.1%,TASCII D型患者各期通畅率均低于TASCII C型患者。Cox多因素回归分析证实,支架总长度、流出道情况是支架术后再狭窄的独立危险因素。结论股腘动脉TASCII C、D型病变支架治疗短期疗效好,但远期通畅率较低,支架长度与流出道是影响远期通畅率的独立危险因素。CDU定期随访对评价疗效,评估再狭窄具有重要的临床价值。Objective To retrospectively analyze the femoropopliteal artery TASCII C and D lesions stenting treatment effectiveness, patency and in-stent restenosis （ISR） related influencing factors. Methods We studied the patient suffered from femoropopliteal artery TASCII C and D lesions received stent, underwent preoperative evaluation and regular follow-up by color duplex ultrasound （CDU）. Hemodynamic changes and patency were observed after stenting. Results The patency at 3, 6, 12, 24 months post-procedure were 92.9%,69.6%,39.2%,28.1%, respec7 tively. TASCII D was associated with lower patency compared with TASCII C in each period. Cox regression analysis indicated that the cumulative stent length, runoff were significant risk factors for ISR in TASC II C and D lesions. Conclusions Cumulative stent length and runoff were significant risk factors for ISR. CDU is a reliable method for monitoring patients with femoropopliteal stenting.
