ABSTRACT

Objective To evaluate the early and mid-term efficacy of endoscopic vein harvesting(EVH) undergoing coronary artery bypass grafting(CABG) in patients over 70 years old.Methods Patients' data of CABG were analyzed retrospectively in General Hospital of Shenyang Military Region from June 2011 to January 2013.400 patients were enrolled in the study according to the inclusion criteria.All patients were divided into two groups by the method of harvesting great saphenous vein (GSV)EVH group (n =200) and open vein harvesting(OVH) group(n =200).Each group was divided into two subgroupsgroup A(age≥70 years old) and group B (age ＜ 70 years old).The number of the group A was 85 in the EVH group and 79 in the OVH group.The number of the group B was 115 in the EVH group and 121 in the OVH group.The intraoperative findings,the quality of GSV and postoperative pain were evaluated,patients were followed up regularly after discharge.Results The postoperative complications occurred in the EVH group such as numbness and edema of lower limb in group A reduced greatly compared with group B(P ＜ 0.05).However,in the OVH group,there were no great difference in group A and group B(P ＞ 0.05) besides the postoperative pain (P ＜ 0.05).Conclusion The early and mid-term efficacy of EVH undergoing CABG is satisfied,especially in the patients over 70 years old.
