title: Endoscopic conduit harvesting and conventional conduit harvesting for coronary artery bypass graft surgery.
abstract: Conventional conduit harvesting used for coronary artery bypass graft for many decades but there has been some wound complication problem. Endoscopic conduit harvesting is a minimal invasive surgery for reduced wounds complication. The authors aimed to compare the result between two techniques.
  
  
  METHODS
  Prospective enroll of 100 patients for elective coronary artery bypass graft surgery. Divided in 2 groups. The first groups was a convention conduit harvesting (C groups) and the second groups was endoscopic conduit harvesting (E groups). The endoscopic conduit harvesting performed using the Maquet Vasoview system under CO2 inflation assisted.
  
  
  RESULTS
  Endoscopic conduit harvesting was successful 94%. Harvest time C group 32.4 mins E group 48.9 mins, ET CO2 C group 40.3, E group 50.9, Wounds infection C group 6% E group O, wounds echymosis C group 6% E group 44%.
  
  
  CONCLUSIONS
  Endoscopic conduit harvesting showed better results with conventional conduit harvesting in wounds with serious complications but they need more harvest time and risk of CO2 embolism. However a long term graft patency needs more investigation.
