大隐静脉旁路术
saphenous vein bypass operation
即“主动脉-冠状动脉大隐静脉旁路术”,俗称“搭桥术”。1967年Garrett用大隐静脉施行左前降支分流移植术后,逐步应用于治疗顽固性心绞痛、急性心肌梗死、严重室性心律失常及导管球囊扩张术后复发狭窄的病例。手术分3个步骤进行:于单侧或双侧大腿或小腿采取大隐静脉约25cm供单根吻合;另一手术组取胸正中切口,显露主动脉根部及梗死的冠状动脉;在体外循环下作冠状动脉大隐静脉吻合术,将取下的大隐静脉倒转与冠状动脉梗死的远端作端-侧吻合;恢复心搏动后,再将大隐静脉另一端与升主动前壁作端-侧吻合,注意避免大隐静脉扭曲。移植大隐静脉,取材方便,长度不受限制,口径够大,操作较方便。但静脉壁薄,承受动脉血后,会造成血管内膜增生,管腔狭窄,影响长期通畅率。术后5年通畅率为70%~80%,10年通畅率仅30%~35%。手术死亡率在5%以内。
