To assess the safety and efficacy of secondary procedures in iliac artery stents.
Thirty-four patients (36 limbs) underwent one or more interventional procedures in iliac artery stents to treat restenosis (n = 30) or occlusion (n = 6). All patients were followed up by means of clinical and angiographic examination. Primary and secondary patency were assessed with angiography, duplex ultrasound, or both. Primary patency was determined after one interventional procedure, and secondary patency was determined at the end of the study (mean +/- standard deviation, 20.1 months +/- 17.5; range, 1-58 months).
Immediate angiographic success was achieved in all cases. Four complications were observed. The primary and secondary cumulative patency rates were 77.5% +/- 7.6 and 94% +/- 4.1 at 6 months, 73% +/- 8.4 and 89.3% +/- 6 at 12 months, and 51.4% +/- 10.9 and 78.8% +/- 8.8 at 2 years. At the end of the study, 80% of the arteries were still nominally patent.
Restenosis and chronic occlusion in iliac artery stents can be treated with percutaneous interventional procedures; however, stenosis can still recur.
评估髂动脉支架二次手术的安全性和有效性。
34例患者(36条肢体)接受了一项或多项髂动脉支架介入手术,以治疗再狭窄(n = 30)或闭塞(n = 6)。所有患者均通过临床和血管造影检查进行随访。通过血管造影、双功超声或两者评估初次通畅率和二次通畅率。初次通畅率在一次介入手术后确定,二次通畅率在研究结束时确定(平均±标准差,20.1个月±17.5;范围,1 - 58个月)。
所有病例均立即取得血管造影成功。观察到4例并发症。6个月时初次和二次累积通畅率分别为77.5%±7.6和94%±4.1,12个月时为73%±8.4和89.3%±6,2年时为51.4%±10.9和78.8%±8.8。在研究结束时,80%的动脉仍名义上保持通畅。
髂动脉支架的再狭窄和慢性闭塞可以通过经皮介入手术治疗;然而,狭窄仍可能复发。
