A New Valvulotome and Its Technique in Angioscopically Assisted Valvulotomy for In Situ Saphenous Vein Bypass / 日本心臓血管外科学会雑誌

ABSTRACT

We encountered a case of femoro-popliteal bypass using the <i>in situ</i> saphenous vein bypass procedure employing a new valvulotome and technique of angioscopically assisted valvulotomy. The new combined angioscope and valvulotome system for the <i>in situ</i> saphenous vein bypass grafting is safe and effective for resection of valve leaflets and to avoid valvulotome-induced injury in comparison with blind retrograde valvulotomy, and allows minimal skin incision through identification of venous tributaries by angioscopic guidance. Further detailed clinical observation may be needed for the evaluation of the long-term benefits of this maneuver.
