title: [Endoscopic Saphenous Vein Harvesting versus Open Vein Harvesting Techniques].
abstract: OBJECTIVE
  To investigate whether endoscopic saphenous vein harvesting (EVH )reduces leg wound morbidity and improves rehabilitation of lower extremity as compared to open vein harvesting (OVH) in patients with coronary artery disease.
  
  
  METHODS
  The clinical data of 333 patients who underwent isolated coronary artery bypass graft surgery (CABG) between January 2007 and December 2011 were retrospectively analyzed.These patients were divided into EVH group (n=210) and OVH group (n=123). Parameters including age,sex,with/without diabetes mellitus,leg wound complications rate,postoperative hospital stay,hospitalization expense,and vein graft patency were analyzed.
  
  
  RESULTS
  The age,sex,with/without diabetes mellitus were not significantly different between two groups (P>0.05). However,the incidences of leg wound complications, poor wound healing, wound infections, wound pain,wound numbness, and edema of lower extremity were significantly lower in the EVH group than the OVH group (P<0.05). The ecchymoma and deep vein thrombosis incidences were not significantly different between these two groups (P>0.05). The postoperative hospital stay showed no significant difference (P>0.05), while the hospitalization expense was significantly higher in the EVH group than in the OVH group (P<0.05). There was no statistical difference of vein graft patency (P>0.05).
  
  
  CONCLUSIONS
  The EVH system is a safe and effective alternative to OVH because it can markedly reduce postoperative leg wound morbidity and the EVH vein graft has good patency.
