STRECKER STENT IMPLANTATION IN ILIAC ARTERIES - PATENCY AND PREDICTIVE FACTORS FOR LONG-TERM SUCCESS

PURPOSE: To evaluate Strecker stent implantation in iliac arteries. MA TERIALS AND METHODS: Sixty-four iliac arteries with Strecker stents we re 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). RESULTS: St ent placement was successful in 63 arteries (98%). The overall complic ation 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 th e 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. CONCLUSION: Use of the Strecker endoprosthesis app ears useful but not ideal. Determination of predictive factors for lon g-term success may help identify indications for its use.
