Purpose. The purpose of this study was to evaluate the technical and mid-term results of primary stent placement for chronic total occlusions (CTO) of the iliac artery, in comparison to stent placement for iliac artery stenosis. Methods. A retrospective study was carried out on 114 consecutive limbs with 24 CTOs and 90 stenoses of the iliac artery that underwent primary stent placement. Primary, assisted primary patency, and limb salvage rates were determined in accordance with the Society for Vascular Surgery guidelines. Results. Angiographic and intravascular ultrasonographic success was achieved in all 114 limbs (100%). Three major complications, including 1 distal embolism and 2 arterial ruptures, occurred in the CTO group. The 2-year primary patency rate in the CTO group was as high as that observed in the stenosis group (91% vs 89%). There were also no signifi cant differences in the assisted primary patency, limb salvage, and survival rates between the two groups. Conclusions. Our results indicate that primary stent placement is a safe and effective treatment for iliac CTOs. However, major complications, including distal embolization and iliac artery rupture, remain a signifi - cant problem, and caution should therefore be exercised when performing this technique for iliac CTOs.
