Abstract:Objective To evaluate the early clinical effect of the application of endoscopy in coronary artery bypass grafting to obtain the great saphenous vein.Methods A total of 262 patients with great saphenous vein obtained by endoscopy in Nanjing Drum Tower Hospital were used to observe the operation status and incidence of postoperative incision complications from June 2019 to October 2023.Results The time to obtain the great saphenous vein was (39.1±9.2) min, and the length was (30.8±7.6) cm. There was no obvious damage to the wall of the great saphenous vein after removal. Subcutaneous ecchymosis occurred in 13 patients, and it could be absorbed and healed by itself after an average of about 10 days. The pain of the leg incision was not obvious, and there was no incision infection, dehiscence or fat liquefaction.Conclusion Obtaining the great saphenous vein through endoscopy with little trauma can bring good early clinical results and improve patient satisfaction and quality of life.
