It is thought that free muscle flaps may remain dependent on their original pedicle for more than 1-year postoperation, particularly in the lower extremity of patients with peripheral vascular disease. We present the first case report of bilateral lower extremity salvage with a single rectus abdominis myocutaneous free flap by transecting the main pedicle. The pedicle of the free flap, going to the contralateral extremity, was safely divided at 6-weeks postoperation. A tourniquet was used to compress the pedicle at the division point to assess viability of the flap distal to the point of occlusion prior to transection of the flap.
一般认为,游离肌皮瓣在术后1年以上可能仍依赖其原蒂部供血,特别是在患有周围血管疾病患者的下肢。我们首次报告了通过横断主蒂,使用单一腹直肌肌皮游离瓣挽救双侧下肢的病例。游离瓣的蒂部在术后6周安全地向对侧肢体进行了离断。在离断皮瓣之前,使用止血带在离断点压迫蒂部,以评估皮瓣在闭塞点远端的存活能力。
