介入治疗股浅动脉硬化闭塞19例分析

目的 探讨股浅动脉硬化闭塞介入治疗的方法和疗效.方法 回顾性分析2005年1月至2008年8月介入治疗的19例(22条下肢)股浅动脉硬化闭塞症患者的临床资料.其中Fontaine Ⅱb期(中、重度间歇跛行)6条,Ⅲ期(静息痛)8条,Ⅳ期(组织缺损)8条(其中足部溃疡6条,足趾坏疽2条).股浅动脉病变的平均长度8.8 cm(5.0～13 cm).病变TASC分型B型4条,C型17条,D型1条.通过彩色血管超声和(或)动脉造影观察病变段动脉术前、术后的影像学改变分析支架通畅率,分析术前、术后临床症状的改善情况,以临床改善率和保肢率来评价临床疗效.结果 17条肢体浅动脉开通(手术成功率77.3%),其中单纯FTA 11例,PTA加支架成形6例,共置入自膨式镍钛合金支架8枚.2例中转旁路手术,3例放弃手术.17条肢体平均随访12.5个月(3～33个月).1例术后1个月死于心心肌梗塞;4条肢体术后3～6个月再闭塞.17条肢体介入手术后1年一期通畅率为76.4%. 结论介入治疗股浅动脉硬化闭寨症有较满意的近期和中期疗效.

Interventional therapy for atherosclerotic occlusive disease of the superficial femoral artery

Objective To explore the methods and mid-term results of interventional therapy for atherosclerotic occlusive disease of the superficial femoral artery(SFA).Methods From January 2005 to August 2008,Nineteen cases with 22 diseased lower limbs were admitted.According to Fontaine stage system,there were 6 stage Ⅱb limbs(moderate to severe intermittent claudication),8 stage Ⅲ limbs(rest pain),and 8 stage Ⅳ limbs(6 with ulcer and 2 with gangrene).The mean lesion length was 8.8 cm(5～13 cm).On the basis of the TransAtlantic Inter-Society Consensus(TASC)femoropopliteal classification,the lesions were classified as type B in 4 limbs,type C in 17,and D in 1.Follow up examinations with color duplex ultrasound and/or arteriography were carried out to determine the patency.The improvement of clinical symptoms after operation was analyzed.Results 17 limbs were revascularization successfully,2 limbs were turned to bypass operation,3 limbs were judged untreatable.The technical success rate is 77.3%,and the clinical improvement of symptoms was achieved in 100% of the 17 limbs on which the procedure was successful.The 17 limbs were followed up for a mean of 12.5 months(range 3-33 months).One patient died of cardia infarction one month postoperatively.SFA occlusion happened in 4 limbs.At one year postoperatively,the patency rate was 75%(13/17)after primary operation.Conclusions Primary endovascular treatment of SFA occlusion diseases is a safe,minimally invasive,and effective method.
