Internal mammary artery (IMA)-based pedicled perforator flaps can be used to reconstruct defects of the neck and anterior chest wall. Pre-expansion causes a possible delay phenomenon, improves flap survival, and decreases donor site morbidity. It also increases the area that can be covered. Pre-expanding can allow for perforator flaps that require a shorter arc of rotation. The pre-expanded internal mammary artery perforator (IMAP) flap is an excellent option for patients who have undergone multiple failed reconstructions and require large amounts of soft tissue while lacking other donor sites.
基于胸廓内动脉（IMA）的带蒂穿支皮瓣可用于修复颈部和前胸壁缺损。预扩张会引发可能的延迟现象，提高皮瓣存活率，并降低供区并发症。它还能增加可覆盖的面积。预扩张可使需要较短旋转弧的穿支皮瓣成为可能。对于经历多次重建失败且需要大量软组织而又缺乏其他供区的患者，预扩张的胸廓内动脉穿支（IMAP）皮瓣是一个极佳的选择。
