经皮血管成形术治疗髂动脉闭塞性病变的技术探讨及疗效评价

目的：探讨经皮血管成形术治疗髂动脉闭塞性病变的技术要点和疗效评价方法。方法：13例髂动脉完全闭塞的患者在我院接受介入治疗,根据髂动脉闭塞的位置、长度和闭塞血管流出道的情况,分别采用顺行开通法、逆行开通法及双向开通法进行治疗。回顾性分析不同闭塞情况下的技术要点,使用踝肱指数和Fontaine分期对介入治疗前后的临床疗效进行评价。结果：13例患者中12例成功开通闭塞的髂动脉,技术成功率为92.3%（12/13）,总并发症率为23.1%（3/13）,采用顺行开通法、逆行开通法、和双向开通法的例数分别为8例、4例和1例。与术前比较,术后患者踝肱指数明显升高（t=5.344,P=0.000）,Fontaine分期显著降低（U=33.5,P=0.019）。结论：经皮血管成形术治疗髂动脉闭塞性病变技术成功率高,创伤小,临床疗效显著,踝肱指数和Fontaine分期可作为评价疗效的客观指标。

Technical exploration and efficacy assessment of percutaneous transluminal angioplasty for iliac arterial obstructive disease

Objective:To explore the technical key points and efficacy assessment methods of percutaneous transluminal angioplasty(PTA) for iliac arterial obstructive disease(IAOD).Methods:13 patients with IAOD underwent PTA treatment in our institution.According to the location,length and outflow tract of diseased iliac artery,antegrade recanalization,retrograde recanalization and bidirectional recanalization were respectively used for treatment of IAOD.The technical key points in different situation were analyzed ret...
