title: [Endovascular angioplasty for the treatment of long iliac artery chronic total occlusions].
abstract: OBJECTIVE
  To evaluate the effectiveness, safety and feasibility of endovascular angioplasty in treating long iliac artery chronic total occlusions (CTO).
  
  
  METHODS
  The clinical data from a consecutive series of patients with long (> 5 cm) iliac artery CTO who treated by endovascular angioplasty from January 2006 to December 2010 was retrospectively analyzed. There were 139 patients (157 limbs) with long iliac artery CTO treated by endovascular angioplasty in this study [male 93 and female 46, mean age (77 ± 10) years]. According to TASC II classification, there were 18 patients in type B, 89 patients in type C and 32 patients in type D. Recanalization of the occluded lesions was attempted with the left brachial and/or femoral access.
  
  
  RESULTS
  The ankle brachial index increased from 0.42 ± 0.19 before treatment to 0.81 ± 0.26 after treatment. The rate of technical success was 96.2% (151/157) and the patency rate of iliac artery was 94.1% (111/118) during the follow-up. Significant restenosis or reocclusion was found in 7 iliac lesions and there were no major interventional complications, such as iliac artery rupture, stent displacement, pseudoaneurysms, and arteriovenous fistula.
  
  
  CONCLUSIONS
  Endovascular angioplasty is an effective, safe and feasible method in treating long iliac CTO with high patency rate. Combined left brachial and femoral access can increase the technical success rate significantly.
