股腘动脉支架断裂与支架内再狭窄相关性分析

摘要

目的 探讨股腘动脉硬化闭塞性病变接受支架植入患者术后发生支架内再狭窄(ISR)与支架断裂的相关性.方法 回顾性随访分析2012年3月至2016年3月采用股浅动脉及近段腘动脉支架一期植入术治疗股腘动脉硬化闭塞性病变患者97例(107条患肢).通过彩色多普勒超声、X线平片、增强CT及DSA造影等检查采集影像学资料,采用Kaplan-Meier生存分析等统计分析相关资料.结果 随访期内71例患者(72条患肢)发生ISR,发生率为67.3％(72/107).支架断裂组、未断裂组ISR发生率分别为84.2％(32/38)、58.0％(40/69),差异有显著统计学意义(P=0.01).结论 股腘动脉支架植入后支架断裂是导致ISR的重要危险因素之一.%Objective To investigate the correlation between femoral popliteal artery stent fracture and in-stent restenosis (ISR) in patients with arteriosclerosis obliterans of superficial femoral artery and proximal popliteal artery after receiving stent implantation.Methods The clinical data of a total of 97 consecutive patients with arteriosclerosis obliterans of superficial femoral artery and proximal popliteal artery (107 diseased limbs in total),who were treated with primary stent implantation during the period from March 2012 to March 2016,were retrospectively analyzed.The imaging materials,including Doppler ultrasonography,plain radiography,contrast-enhanced CT scan,DSA,etc.were collected,and Kaplan-Meier survival analysis and other statistical analysis methods were used to analyze the related data.Results During the follow-up period,71 patients (72 limbs in total) developed ISR and the incidence of ISR was 67.3％ (72/107).The incidences of ISR in the stent-fracture group and non-fracture group were 84.2％ (32/38) and 58.0％ (40/69) respectively,the difference between the two groups was statistically significant (P=0.01).Conclusion After stent implantation of femoral popliteal artery,fracture of stent is one of the important risk factors for the occurrence of ISR.
