Leg Wound Complications: A Comparison Between Endoscopic and Open Saphenous Vein Harvesting Techniques.

Abstract

The most common conduit for coronary artery bypass graft (CABG) surgery is saphenous vein graft (SVG). There are two techniques for SVG harvesting: open and endoscopic. Our aim is to evaluate clinical results of endoscopic versus open SVG harvesting. Nowadays, endoscopic vein harvesting (EVH) has become prevalent because of reduced complications with more patient satisfaction. We designed and performed a prospective randomized cohort study of patients undergoing CABG to compare the results of open versus endoscopic harvesting technique. Patients who underwent elective CABG at our hospitals were divided into two groups, during the period of January 2019 to March 2021. The EVH group (50 patients) underwent endoscopic technique compared with the open vein harvesting (OVH) group (50 patients) that was underwent open surgical incision for great saphenous vein (GSV) harvesting. The two groups demographically were similar and received identical management. Leg wound was evaluated at discharge, two weeks, and four weeks for evidence of any complications. Early outcomes were recorded, including infection, gaped wound and surgical re-suture, degree of pain, level of cosmetic satisfaction, and early mobilization. In the EVH group, harvesting time increased, and incision closure time decreased in comparison with OVH. The hospital stay was 5.5 ± 2.4 days in the EVH group versus 9.5 ± 2.7 days in the OVH group. Leg wound complications were significantly reduced in the EVH group in comparison with the OVH group. Endoscopic vein harvesting technique reduced leg wound complications. Conveniently, patients also were cosmetically satisfied.
