Abstract:
ObjectiveTo summarize the one-year follow-up clinical result of patients undergoing Endoscopic vein harvest (EVH) technology to collect greater saphenous vein( GSV )in coronary artery bypass operation (CABG),and to assess the related factors influencing the outcome.Methods248 patients underwent off-pump coronary artery bypass grafting (OPCAG) from May 2009 to May 2010.Among these patients,136 patients with coronary artery disease received EVH technology to gain GSV,and 112 patients received conventional open vein harvesting (OVH).Then 71 EVH (group 1 ) patients and 64 OVH ( group 2 ) patients had one-year follow-up analysis.We compared and evaluated the data of two groups about operation information,lower limb wound complication,bridge blood vessels patency rate,and psychologic status.ResultsThe date of wound surface size,wound healing and appearance,wound infection rate,the second debridement rate and the overall lower limb wound complication rate show that EVH was better than OVH.After one-year follow-up,we contrasted the patency rate of bridge blood vessels between two groups.The patency rate of arterial bridge blood vessels was 96.8％ ( venous bridge blood vessels was 85.7％ )in group of EVH when we followed up 63 patients;while the patency rate of arterial bridge blood vessels was 94.9％ ( venous bridge blood vessels was 86.4％ ) in group of OVH that we followed up 59 patients.We compared the outcome between two groups,and found that there were no statistical significance in angina recurrence rate,patency rate of venous graft and patency rate of arterial graft.But the psychologic status was different,the EVH group was better than OVH group.ConclusionCompared to OVH,EVH technique has more advantages.Through taking a more secure method in the collection process of the bridging vein material,EVH group also maintained a satisfactory one-year graft patency rate.
