title: The Results of Self-Expandable Kissing Stents in Aortic Bifurcation.
abstract: OBJECTIVE
  Kissing stent reconstruction is a widely used technique for the management of aortoiliac occlusive disease involving the aortic bifurcation or proximal common iliac arteries. The purpose of this study was to evaluate the results of self-expandable kissing stents in the aortic bifurcation.
  
  
  METHODS
  We reviewed medical records of the patients treated with a kissing stent retrospectively from January 2007 to December 2012. The primary and secondary patencies were determined with Kaplan-Meier analysis, and Cox regression was used to determine the factors associated with patency.
  
  
  RESULTS
  A total of 21 patients were included, and all were male (median age 53±15 years, range 48-78 years). Major symptoms were claudication (n=16, 61.9%), rest pain (n=5, 23.8%) and gangrene (n=5, 23.8%). Tans-Atlantic Inter-Society Consensus for the Management of Peripheral Arterial Disease (TASC) II classification was A 2 (9.5%), B 5 (23.8%), C 7 (33.3%) and D 8 (38%). The mean follow-up was 40.7 months. Major complication occurred in only one case which consisted of distal limb ischemia by emboli. Six patients developed symptomatic restenosis or occlusion. There was no major amputation, but minor amputation occurred in 3 patients. There were 2 mortalities not associated with the procedure (lung cancer and intracranial hemorrhage). Primary patency was 89.6% at 1 year, 74.7% at 3 years and 64.0% at 5 years. Secondary patency was 94.1% at 1 year, 88.2% at 3 years and 68.6% at 5 years. No risk factors for restenosis or occlusion were identified.
  
  
  CONCLUSIONS
  Self-expandable kissing stents can be used successfully with comparable patency for endovascular treatment of symptomatic atherosclerotic occlusive lesions in the aortic bifurcation area.
