The main flaps derived from the abdominal wall are described, indicating the following points for each one: vascular anatomy, the cutaneous and/or muscle territory of the flap, the arc of rotation, the main applications and finally comments concerning certain specific anatomical or technical points. Rectus abdominis flaps are by far the most frequently used in routine clinical practice for mammary reconstruction and cover of the thorax, abdomen or groin areas. Groin flaps are also frequently used, either as pedicled flaps to cover defects of the upper extremity or abdomen, or as free flaps, especially for mandibular reconstructions.
