TASC C\/D lesions were present in 72% and iliac complete occlusion in 30%. Mean lesion length was 6.9\u2009\u00b1\u20092.4\u00a0cm; 30% had moderate\/severe EIA calcifications; and the mean iliac tortuosity index was 1.17\u2009\u00b1\u20090.13. Technical success was 100%. There was one perioperative death (1.4%) and procedural complication rate was 6.5%.
