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.
Material and Method: 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 0, wounds echymosis C group 6% E group 44%.
Conclusion : 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.
