Self-expandable stents of the Wallstent type were used in 26 iliac and 15 femoropopliteal artery lesions of 31 patients to treat stenoses or occlusions. The indications were confined to complex lesions, including residual stenoses and dissections after percutaneous procedures or previous surgery in the iliac artery lesions, and long-segment (mean, 13.5 cm) occlusions with inadequate response to percutaneous recanalization in the femoropopliteal artery lesions. In the iliac artery group, after stent placement, 96% of the lesions were patent at a mean follow-up of 16 months (range, 6-30 months). In the femoropopliteal artery group, of 11 patients available for follow-up, only six had patent stents at 7-26 months (mean, 20 months). Four of these six patients required one to three secondary interventions. Self-expanding endoprostheses are of great value in complex iliac artery lesions where simple balloon dilation is insufficient. Stent placement for long femoral artery lesions should be performed with utmost reserve, and the extent of stent placement should be as short as possible.
31例患者的26处髂动脉病变和15处股腘动脉病变使用了Wallstent型自膨式支架来治疗狭窄或闭塞。适应证仅限于复杂病变，包括髂动脉病变经皮操作或既往手术后的残余狭窄和夹层，以及股腘动脉病变中对经皮再通反应不佳的长段（平均13.5 cm）闭塞。在髂动脉组，支架置入后，平均随访16个月（范围6 - 30个月）时，96%的病变保持通畅。在股腘动脉组，11例可进行随访的患者中，仅6例在7 - 26个月（平均20个月）时支架保持通畅。这6例患者中有4例需要进行1至3次二次干预。自膨式腔内假体在单纯球囊扩张不足的复杂髂动脉病变中具有很大价值。对于长段股动脉病变，应极其谨慎地进行支架置入，且支架置入范围应尽可能短。
