title: Outcomes of endovascular treatment for TASC C and D aorto-iliac lesions.
abstract: OBJECTIVE
  The aim of this study was to evaluate the technical success rates, primary patency, and complications for TASC C and D aorto-iliac lesions treated by endovascular procedures. Additionally, the influence of the access site and the clinical outcomes were analyzed.
  
  
  METHODS
  Between 2008 and 2014, data from 39 patients with 45 chronic iliac artery stenosis and/or occlusion who were treated with endovascular treatment were retrospectively reviewed.
  
  
  RESULTS
  The procedure time was longer for TASC D lesions than for TASC C lesions (163 ± 82 min vs. 105 ± 34 min; p = 0.002), where there was the more common use of brachial and femoral approach simultaneously. There were two perioperative deaths associated with TASC D lesions caused by one iliac artery rupture and one postoperative hospital-acquired pneumonia. The total perioperative complication rate was higher in the TASC D lesions than in TASC C lesions [five (18.5%) vs. zero; p = 0.073]. The corresponding 2-year primary patency rates were 94.9% in TASC C lesions and 88.4% in TASC D lesions. The simultaneous brachial and femoral approach took the longest procedure time (226 ± 157 min).
  
  
  CONCLUSIONS
  This study demonstrated that the outcomes of endovascular treatment for TASC C and D aorto-iliac lesions were acceptable, with better technical success in TASC C lesions than in TASC D lesions. Furthermore, the 2-year patency rate for both TASC C and TASC D lesions was acceptable. Additionally, brachial access was useful for complex anatomy, but the failure rate was high.
