Sixteen symptomatic iliac artery stenoses and three occlusions in 16 patients were treated by the percutaneous implantation of Wallstent endoprostheses (Medinvent SA, Lausanne, Switzerland). The endoprosthesis consists of stainless steel monofilaments braided into a self-expanding cylinder. The indications for placement were restenosis after angioplasty (10 cases), failed arterial dilations (eight cases), and restenosis after endarterectomy (one case). The prostheses used had a mean diameter of 8 mm (range, 6-10 mm) and were placed in the external iliac (14 cases) and common iliac (five cases) arteries. The 16 stenoses were greater than 80%, and the three occlusions were longer than 7 cm. Mean length of the lesions treated was 7 cm (range, 4-14 cm). Three of the arteries thrombosed after treatment, one 2 days later and two in the month after implantation of the stent. On clinical and angiographic follow-up (mean, 16 months; range, 1-24 months) no symptoms or stenoses reappeared in the remaining 16 cases. Our experience in these cases suggests that implantation of a Wallstent endovascular prosthesis is a valuable technique for the treatment of external and common iliac artery stenoses.
16例患者的16处有症状的髂动脉狭窄和3处闭塞病变，通过经皮植入Wallstent血管内支架（瑞士洛桑Medinvent SA公司）进行治疗。该血管内支架由编织成自膨式圆筒的不锈钢单丝构成。植入指征为血管成形术后再狭窄（10例）、动脉扩张失败（8例）和动脉内膜切除术后再狭窄（1例）。所用支架的平均直径为8mm（范围6 - 10mm），分别植入于髂外动脉（14例）和髂总动脉（5例）。16处狭窄均大于80%，3处闭塞均长于7cm。所治疗病变的平均长度为7cm（范围4 - 14cm）。治疗后3条动脉发生血栓形成，1条在2天后，2条在支架植入后1个月内。在临床和血管造影随访（平均16个月；范围1 - 24个月）中，其余16例未再出现症状或狭窄。我们在这些病例中的经验表明，植入Wallstent血管内支架是治疗髂外动脉和髂总动脉狭窄的一种有价值的技术。
