JAHA:紫杉醇洗脱球囊在血管再狭窄患者中同样具有更好的疗效

2017-07-26 MedSci MedSci原创

目前来说,相比于传统的球囊血管成形术(BA),紫杉醇洗脱的球囊(PEB)血管成形术在治疗浅表股动脉病变(SFA)上具有明显的优势,但是对于PEB和BA治疗血管内支架置入术后再狭窄的效果如何尚未阐明。近日,在国际心血管权威杂志JAHA上发表了一篇旨在评估比较PEB和BA治疗支架置入术后再狭窄效果的随机临床研究。本研究将有症状的支架置入术后再狭窄的患者随机分成PEB治疗组和BA治疗组,主要终点事件是6

目前来说,相比于传统的球囊血管成形术(BA),紫杉醇洗脱的球囊(PEB)血管成形术在治疗浅表股动脉病变(SFA)上具有明显的优势,但是对于PEB和BA治疗血管内支架置入术后再狭窄的效果如何尚未阐明。近日,在国际心血管权威杂志JAHA上发表了一篇旨在评估比较PEB和BA治疗支架置入术后再狭窄效果的随机临床研究。

本研究将有症状的支架置入术后再狭窄的患者随机分成PEB治疗组和BA治疗组,主要终点事件是6~8个月随访血管造影中的动脉狭窄的百分比,次要终点事件是随机过程中出现的二次再狭窄发生率和靶病变血运重建、靶血管血栓形成、同侧截肢、受累肢体搭桥手术和24个月随访时间内的全因死亡率。最终共纳入了70例研究对象,36例被分入PEB治疗组,34例被分入BA治疗组。患者的平均病变血管长度是139±67 mm,约三分之一被完全阻塞。相比于对照组的血管造影,血管的狭窄比例(44±33% vs 65±33%, P=0.01)和再狭窄发生率(30% vs 59%, P=0.03)在PEB治疗组和BA治疗组均有明显的降低。在长达24个月的随访后,相比于BA治疗组,PEB治疗组的靶血管血运重建率要显着降低(19% vs 50%, P=0.007),而其他终点事件无显着差异。

研究结果表明,相比于传统球囊血管成形术,紫杉醇洗脱球囊血管成形术具有更好的血管造影随访结果和临床疗效。
