Abstract:
We report the preoperative evaluation of saphenous vein (SV) graft using plain computed tomography (CT) for endoscopic saphenous vein harvesting (EVH). We made three-dimensional (3D) images of SV by using plain CT images. EVH was performed in 33 patients from July 2019 to September 2020. The mean age of the patients was 69±23 years, and 25 patients were men. The success rate of EVH was 93.9%. Hospital mortality was 0%. Postoperative wound complications was 0%. The early patency was 98.2% (55/56). 3D images of SV by plain CT are very important information for EVH because of surgical procedure in a closed space. Early patency is good and mid and long term patency of EVH may be improved due to safety and gentle technique by CT information.
