球囊扩张腔内支架用于治疗传统球囊血管成形术无效的髂动脉狭窄或闭塞。共进行了171例手术，其中48例有截肢风险。重度跛行36例，中度间歇性跛行70例。在最近的随访检查中(平均6个月；范围1-24个月)，137名患者显示出临床益处，其中113名患者已变得没有症状。11名患者最初没有显示出任何益处，6名患者最初有所改善，但后来出现了新的血管症状。发生并发症18例。在三名患者中，并发症与该设备直接相关。两个闭塞成功再通，球囊穿孔后的血管壁间造影剂收集进展顺利。其余患者分别为腹股沟血肿6例，远端栓塞4例，渗出2例，一过性肾功能衰竭1例，穿刺点假性动脉瘤1例，内膜下夹层1例。所有支架在最新的随访检查中都保持开放，没有移位或动脉瘤形成的证据。
Balloon-expandable intraluminal stents were used to treat iliac artery stenoses or occlusions that failed to respond to conventional balloon angioplasty. One hundred seventy-one procedures were performed in 154 patients, of whom 48 had a limb at risk for amputation. Thirty-six had severe and 70 had moderate intermittent claudication. At the latest follow-up examination (average, 6 months; range, 1-24 months), 137 patients demonstrated clinical benefit, 113 of whom had become asymptomatic. Eleven patients showed no initial benefit, and six improved initially but later developed new vascular symptoms. Complications occurred in 18 patients. In three patients, complications were directly related to the device. Two occlusions were successfully recanalized, and an intramural collection of contrast material secondary to balloon perforation evolved favorably. The remaining patients had groin hematoma (n = 6), distal embolization (n = 4), extravasation (n = 2), transient renal failure (n = 1), pseudoaneurysm at the puncture site (n = 1), or subintimal dissection (n = 1). All stents have remained patent to the latest follow-up examination without evidence of migration or aneurysm formation.
