The pectoralis major musculocutaneous (PMMC) flap is a versatile and commonly used technique for reconstruction of the head and neck in patients at high risk in free tissue transfer procedures. In this report, a "supercharged" PMMC flap, in which the lateral thoracic artery was cut, preserved, and anastomosed to the cervical vessels, was developed to stabilize blood flow.
The supercharged PMMC flap was introduced in a patient who was at high risk for partial necrosis of the flap and underwent surgery for reconstruction of the tongue. Intraoperative perfusion monitoring using laser-assisted indocyanine green angiography (ICGA) was also performed to verify the status of blood flow in the flap.
ICGA monitoring of blood flow in the flap revealed instability. Subsequently, a supercharged PMMC flap was applied, which prevented partial necrosis of the flap.
Combined with ICGA, a supercharged PMMC flap contributed to successful reconstruction in a patient at high risk for necrosis of the flap region.
胸大肌肌皮瓣（PMMC）是一种多功能且常用的技术，用于在游离组织移植手术中对高风险患者进行头颈部重建。在本报告中，开发了一种“增压”PMMC瓣，即切断、保留胸外侧动脉并将其与颈部血管吻合，以稳定血流。
在一名皮瓣部分坏死风险高且接受舌重建手术的患者中引入了增压PMMC瓣。还使用激光辅助吲哚菁绿血管造影（ICGA）进行术中灌注监测，以验证皮瓣中的血流状况。
ICGA对皮瓣血流的监测显示血流不稳定。随后应用了增压PMMC瓣，从而防止了皮瓣部分坏死。
结合ICGA，增压PMMC瓣有助于在皮瓣区域坏死风险高的患者中成功进行重建。
