title: Role of surgical treatment for peripheral arterial disease in endovascular era.
abstract: OBJECTIVE
  The purpose of this study is to review the roll changes of surgical treatment for peripheral artery disease in endovascular era.
  
  
  METHODS
  One hundred and twelve surgically treated cases of peripheral artery disease at a single institution during the period from 2006 to 2011 were studied retrospectively. The cases were divided into two groups of different time periods, one before 2009 (surgical period group) and the other from 2009 onward (endovascular period group). We analyzed the type and location of surgery as well as clinical characteristics of patients and treatment results.
  
  
  RESULTS
  Fifty-three cases were for the surgical period group and 59 cases for the endovascular group. No difference in the demographic characteristics and the distribution of major atherosclerosis risk factors was found between the two groups. Additionally, the technical and functional success rate was similar in both groups. However, it is found that there were more acute cases in the endovascular period group than in the surgical period group. The number of cases in need of suprainguinal or below knee exposure was similar in both groups. In hybrid cases, suprainguinal or below knee exposures were more frequently needed during the former period than the latter period.
  
  
  CONCLUSIONS
  The role of surgical treatment is currently in the process of changing. Surgical treatment seems to be a complementary alternative to endovascular treatment for chronic limb ischemia. However, it still seems to play a major role for acute limb ischemia.
