In situ saphenous vein bypass is a technique of lower-extremity revascularization that is gaining popularity as an alternative to the reversed saphenous vein graft. In the latter, the saphenous vein is removed from its bed and reversed before arterial anastomosis. The former uses the vein in situ after the venous valves are made incompetent and the perforators are ligated. Only the proximal and distal ends of the vein are mobilized for anastomosis. The radiologist assists in the management of these patients by performing preoperative venography, intraoperative arteriography, and postoperative arteriography when required. Techniques of these procedures, along with normal and abnormal findings, are discussed.
原位大隐静脉搭桥术是一种下肢血管重建技术，作为逆行大隐静脉移植的替代方法正逐渐受到欢迎。在逆行大隐静脉移植术中，大隐静脉从其床部取出并翻转后进行动脉吻合。而原位大隐静脉搭桥术是在使静脉瓣膜功能不全并结扎穿支静脉后，原位使用该静脉。仅游离静脉的近端和远端用于吻合。放射科医生通过在必要时进行术前静脉造影、术中动脉造影和术后动脉造影来协助管理这些患者。本文将讨论这些操作技术以及正常和异常表现。
