To evaluate Strecker stent implantation in iliac arteries.
Sixty-four iliac arteries with Strecker stents were prospectively studied. Stents were placed for dissection (n = 31), total occlusion (n = 28), unsatisfactory results (n = 3) or restenosis (n = 1) after percutaneous transluminal angioplasty, and a calcified atherosclerotic lesion that bulged into the lumen (n = 1).
Stent placement was successful in 63 arteries (98%). The overall complication rate was 12% (n = 8). During follow-up, three patients died. The stent was compromised in 18 cases because of hyperplasia (n = 10) or occlusion (n = 8). The primary patency rate was 84% at 1 year and 69% at 2 years; the secondary patency rate was 90% at 1 year and 81% at 2 years. Initial dissection (P = .046), a length of 60 mm or less for the stent region (P = .007), and total covering of the abnormal segment with the stent (P = .03) were significant predictive factors for good, long-term results.
Use of the Strecker endoprosthesis appears useful but not ideal. Determination of predictive factors for long-term success may help identify indications for its use.
评估施特雷克支架在髂动脉中的植入情况。
对64条植入施特雷克支架的髂动脉进行前瞻性研究。植入支架的原因包括经皮腔内血管成形术后夹层形成（n = 31）、完全闭塞（n = 28）、效果不佳（n = 3）或再狭窄（n = 1），以及向管腔内突出的钙化动脉粥样硬化病变（n = 1）。
63条动脉（98%）成功植入支架。总体并发症发生率为12%（n = 8）。随访期间，3例患者死亡。18例出现支架相关问题，原因是增生（n = 10）或闭塞（n = 8）。1年时的初级通畅率为84%，2年时为69%；1年时的次级通畅率为90%，2年时为81%。初始夹层形成（P = .046）、支架区域长度为60 mm或更短（P = .007）以及支架完全覆盖异常节段（P = .03）是良好长期效果的显著预测因素。
施特雷克腔内假体的应用似乎有用但并不理想。确定长期成功的预测因素可能有助于明确其使用指征。
