Abstract:

Objective To ascertain blood supply distribution of the sartorius perforators,including myocutaneous branches and direct cutaneous perforator, and provide anatomic basis for clinical application of sartorius perforator flap. Methods Twelve fresh unfixed corpses with red latex injection were dissected layer by layer. The distribution characteristics of dominant arteries of sartorius and the number of perforators were observed and analyzed.   Results   There were generally 7~12 perforating branches in sartorius muscle, from femoral artery, lateral femoral circumflex artery or descending genicular artery. The middle and inferior parts of sartorius received 3-4 myocutaneous perforators and 2-3 intermuscular space perforators originated from femoral artery, with the average external diameter of (1.7±0.6)mm, and the pedicle length of  (2.8±1.2)cm. The perforators from the same origin were common. Conclusions Considering that perforating branches appeared in the lower part of sartorius muscle are abundant and constant, which is more feasible to design flap for tissue defect repair.
