The rectus abdominis flap offers a number of advantages over other flaps used in head and neck reconstruction. The flap can be harvested by a separate team and can be tailored to include skin, muscle, and fat. In addition, the available vascular pedicle is long and its large caliber provides an appropriate size match with recipient neck vessels. Central to reconstructive success is defining an arterial and venous pedicle that provides balanced perfusion to all components of the flap. Anomalous vascular anatomy presents principal challenges in reestablishing free flap perfusion. We present a case of double, right deep inferior epigastric arteries encountered during vertical rectus abdominis myocutaneous flap reconstruction of the tongue and floor of the mouth and discuss the clinical outcomes of this reconstruction.
与用于头颈部重建的其他皮瓣相比，腹直肌皮瓣具有许多优势。该皮瓣可由另一组人员进行切取，并且可以根据需要进行调整，包括皮肤、肌肉和脂肪。此外，其可用的血管蒂较长，管径较大，与受区颈部血管的大小匹配度适宜。重建成功的关键在于确定一条能为皮瓣所有成分提供均衡灌注的动静脉蒂。血管解剖结构异常给游离皮瓣灌注的重建带来了主要挑战。我们报告了一例在舌和口底垂直腹直肌肌皮瓣重建过程中遇到双支右侧腹壁下深动脉的病例，并讨论了该重建的临床结果。
