BACKGROUND: We evaluated whether vessel diameters measured by preprocedural computed tomography angiography (CTA) affects the immediate and late outcomes of endovascular therapy for iliac artery diseases.Methods and Results:A total of 254 patients who underwent endovascular treatment for iliac artery diseases were retrospectively evaluated. Minimum vessel diameters were measured on preprocedural CTA images at target lesions, common iliac arteries, and external iliac arteries (EIA). Predictors of immediate and late procedural outcomes were analyzed. Procedural failure or vessel-specific complications occurred in 29 patients (11%): wire passage failure (n=10), rupture (n=8), and distal embolization (n=11). Target lesion revascularization (TLR) was required in 6.0% at 2 years. Independent predictors of procedural failure or vessel-specific complications were small minimum vessel diameter of the target lesion (odds ratio [OR]=0.68, P=0.008) or EIA (OR=0.67, P=0.008), and chronic total occlusions (OR=3.78, P=0.036). Small minimum EIA diameter (hazard ratio [HR]=0.66, P=0.017) and chronic total occlusions (HR=4.45, P=0.024) were independent predictors of TLR in patients with technical success.

CONCLUSIONS: Small vessel diameter of the target lesion or EIA was an independent predictor of procedural failure or vessel-specific complications. Small vessel diameter, particularly of the EIA, was also associated with increased TLR after successful endovascular therapy for iliac artery lesions.
