[A new technique to prepare non-reversed autovein graft].

Non-reversed autovein graft was prepared by using a long saphenous vein. Disposable enema-syringe was used for vein graft to be turned inside out easily, and venous valves were resected out completely. After these procedure, a graft was put with syringe again, and turned outside in with same maneurver. Then, a non-reversed autovein graft without valves was prepared. We believe this is an excellent method to prepare non-reversed valveless autovein graft to be used as bypass grafting for cardiovascular surgery.
