Abstract
BACKGROUND: The free gracilis perforator flap is a fascioadipocutaneous flap on the medial thigh, based on perforators of the main pedicle of the gracilis myocutaneous flap. METHODS: An anatomical study was performed using 43 cadaver dissections. The vascular anatomy of the gracilis perforator flap with regard to myocutaneous and septocutaneous perforators was assessed. Clinical application was demonstrated in 14 cases. RESULTS: Musculocutaneous perforators of the gracilis muscle pedicle were present in all dissections and were 0.5 mm or more in 93 percent. Septocutaneous perforators were found in 84 percent of the dissections, and perforators of 0.5 mm or more were found in 63 percent. Most musculocutaneous perforators were found in the anterior quarter of the muscle where the pedicle enters the gracilis muscle. A constant intramuscular anastomosis between the main and second vascular pedicles of the gracilis was demonstrated that allowed design of an extended gracilis perforator flap. CONCLUSIONS: Successful clinical application in 14 cases confirmed vascular reliability. The gracilis perforator flap is a pliable, thin flap from the medial thigh that can be as large as 18 x 15 cm. The donor site is inconspicuous, and a functional gracilis muscle is preserved. By including a constant intramuscular anastomosis, it is possible to extend the territory of the free flap distally up to a length of 27 cm. Indications include reconstruction of cutaneous defects such as unstable scars or contractures. The medial thigh adipose tissue correlates well with the body mass index and thus can be used for breast reconstruction as a second choice if an abdominal perforator flap is not available.
