BACKGROUND - The no-touch saphenous vein harvesting is considered to be an ideal procedure for the quality of vein, whereas endoscopic vein harvesting is considered to be ideal for decreasing wound complications. We developed a new technique of endoscopic vein harvesting with perivascular tissue preservation and reported that saphenous vein has histological feature like no-touch saphenous vein.
METHODS - This procedure was achieved by dissecting the immediate anterior and posterior perivascular connective tissues of a saphenous vein followed by cutting approximately 1 cm laterally from the saphenous vein with the use of a harvester (MAQUET Getinge Group, Getinge AB, Göteborg, Sweden). For the prevention of graft twisting, a skin marker was used to make marking on anterior surface of saphenous vein.
RESULTS - 31 SVGs of 16 cases (June, 2021-Nov, 2022) were harvested with NT-EVH. The average harvesting time was 55±13 min. The graft patency was 100 %(26/26) and no wound complications were occurred.
CONCLUSIONS - No-touch EVH has great advantages for prevention of wound complications. Further investigations about long term graft patency are needed.
