Obstruction or stenosis of the iliac artery was treated by placement of a self-expandable stent in 91 patients. A total of 100 lesions was treated. All patients had had poor results of balloon angioplasty including residual stenosis, iliac occlusion, and dissection. The stent used in all cases was a self-expandable stainless steel endoprosthesis mounted on a 7- or 9-French catheter and covered by an invaginated tubular rolling membrane. The diameter of the expanded stent varied from 7 to 12 mm. A total of 129 stents was placed. Technical success was 97%. Thromboses occurred immediately after placement in two patients and within the first month in six; these were mainly due to residual obstruction. Eighty-two (93%) of 88 patients with a follow-up longer than 3 months had no recurrent symptoms. Restenosis caused by intimal hyperplasia inside the stent occurred in 10 patients; these required repeated intervention in only four cases. In the remaining six patients, no further complications occurred. Our results show that self-expanding endoprostheses are of value for improving the results of inadequate percutaneous transluminal angioplasty.
91例患者通过植入自膨式支架治疗髂动脉阻塞或狭窄。共治疗100处病变。所有患者球囊血管成形术效果不佳，包括残余狭窄、髂动脉闭塞和夹层形成。所有病例使用的支架均为安装在7或9法国导管上的自膨式不锈钢内支架，并覆盖有内翻管状滚动膜。扩张后支架直径为7至12毫米。共植入129枚支架。技术成功率为97%。2例患者在植入后立即发生血栓形成，6例在第一个月内发生；这些主要是由于残余阻塞所致。88例随访超过3个月的患者中，82例（93%）无复发症状。10例患者发生支架内内膜增生导致的再狭窄；其中仅4例需要再次干预。其余6例患者未出现进一步并发症。我们的结果表明，自膨式内支架对于改善经皮腔内血管成形术效果不佳的情况具有价值。
