The rectus abdominus free flap was first described by Brown et al. in 1975. Since then, this myocutaneous flap has been used in the reconstruction of many areas of the body and the head and neck. Arterial supply of the flap is from the deep inferior epigastric artery, a branch of the external iliac artery, with drainage by two venae comitantes that combine into a single deep inferior epigastric vein draining into the external iliac vein. The vascular anatomy is extremely consistent and reliable. The pedicle consists of a large caliber vessel with significant length. Although the rectus abdominus free flap has been less utilized due to increased popularity of other myocutaneous flaps such as the anterolateral thigh free flap, there are various benefits and uses.
