The anatomy of several free flap donor sites.

The vascular anatomy of the supplying vessels to the iliofemoral, the deltopectoral, the axillary, and the thoracoabdominal regions has been investigated in detail in fresh cadavers. Other donor sites were also examined. The anatomical relationship of the supplying vessels is discussed-and the design, conversion, and utilization of these skin areas as donor sites for free flap transfer are detailed. The iliofemoral region is suggested as the best donor site for most free flap procedures.
