Peculiar indications for the pedicled or free rectus abdominis flap in reconstructive surgery. A review of our experience.
Among all known flaps, the rectus abdominis muscle flap possesses an unique diversity in flap designs due to the special vascular supply of the abdominal wall. The axial vascularization of the rectus abdominis muscle gives ofF several musculocutaneous perforators, which are mainly located in the periumbilical region. Abdominal wall skin perfusion is guaranteed by spoke-wheel like vessels arising from these perforators. Subsequently several designs (muscle, myocutaneous and myosubcutaneous) are possible, by varying the included tissue and the position of the skin island. We described 7 cases where the rectus abdominis muscle was used as a muscle or myocutaneous flap for reconstruction of large defects. In most cases a pedicled transfer was necessary, possible and sufficient to reconstruct the difficult defects in various body regions. Great amounts of well perfused tissue can be transferred with still possible primary closure of the donor site. Due to its rich perfusion and constancy of vascular pattern, it represents an excellent and safe pedicled reconstructive procedure for large defects of the thorax, the abdomen, the forearm or the hip and pelvis where free tissue transfers are impossible or contraindicated. No other local transposition would have achieved this goal, due to the lack of volume and mobility. Moreover the flap is ideal for reconstruction of contour deficiencies due to the abundance of fat, as for example in breast or buttock reconstruction. However the flap is not the first choice for traumatic and infected wounds where fat tissue is not desired.
