Ten patients with symptomatic iliac artery stenosis underwent percutaneous insertion of balloon-expandable intravascular stents. A total of 12 stents were inserted in the common iliac (7 patients) and external iliac (3 patients) arteries. The indications for placement were unsuccessful angioplasty (5 cases), to improve inflow prior to a subsequent distal bypass graft (3 cases) and localized iliac disease in patients deemed unfit for aorto-femoral by-pass surgery (2 cases). Of the 10 patients, five had rest pain and five had severe intermittent claudication at distances varying from 25 to 75 yards, prior to the procedure. Ankle-Arm Doppler systolic pressure indices increased from a mean of 0.61 to 0.91 post procedure. Eight of the 10 patients are asymptomatic at follow-up, average 12 months (range 8-18 months). One patient died from an unrelated cause and the other patient remains symptomatic due to distal disease (Table 1). Our experience suggests that percutaneous insertion of balloon-expandable intravascular stents is a valuable technique for treatment of external and common iliac stenosis.
10例有症状的髂动脉狭窄患者接受了球囊扩张式血管内支架的经皮置入术。共在7例患者的髂总动脉和3例患者的髂外动脉置入了12枚支架。置入支架的指征包括血管成形术失败（5例）、在后续远端旁路移植术前改善血流（3例）以及被认为不适合进行主-股动脉旁路手术的患者的局限性髂动脉疾病（2例）。10例患者中，5例术前有静息痛，5例有严重间歇性跛行，行走距离在25至75码不等。术后踝臂多普勒收缩压指数从平均0.61升至0.91。10例患者中有8例在平均12个月（范围8 - 18个月）的随访中无症状。1例患者死于无关原因，另1例患者因远端疾病仍有症状（表1）。我们的经验表明，球囊扩张式血管内支架的经皮置入术是治疗髂外动脉和髂总动脉狭窄的一项有价值的技术。
