The free fibular osteocutaneous flap is a commonly used donor for reconstruction of mandibular defects. Vascular abnormalities and leg trauma are relative contraindications to the use of a fibular free flap. Peroneal arteria magna (PAM) is one such vascular abnormality that may preclude the use of the graft due to the high risk of lower-limb ischemia. Lower-limb angiography is the standard for assessing the lower-limb vascular anatomy; however, the indications remain controversial. Although balloon occlusion has been used to assess the vascular supply in distal bypass surgery, there have no reported cases of balloon occlusion to assess the viability of the distal extremity with PAM. Intraoperative assessment of vascular anatomy with an aborted harvest can lead to significant morbidity and cost. Balloon occlusion provides a relatively safe and minimally invasive technique for assessment of potential lower-limb ischemia in patients with PAM.
游离腓骨骨皮瓣是下颌骨缺损重建的常用供区。腓动脉异常和腿部创伤是游离腓骨皮瓣使用的相对禁忌证。巨腓动脉（PAM）是一种血管异常，由于下肢缺血风险较高，可能会导致移植物无法使用。下肢血管造影是评估下肢血管解剖结构的标准方法；然而，适应证仍存在争议。尽管球囊阻塞已用于评估远端旁路手术中的血管供应，但尚无报道使用球囊阻塞评估 PAM 患者远端肢体的存活情况。术中放弃采集来评估血管解剖结构可能会导致严重的发病率和成本。球囊阻塞为评估 PAM 患者潜在下肢缺血提供了一种相对安全和微创的技术。
