PURPOSE: To evaluate the application of the medial sural artery perforator flap (MSAPF) aided by preoperative ultrasonic perforator localization for postsurgical @entity1697 . MATERIALS AND METHODS: From November 2013 to August 2014, 25 @entity1 with @entity1697 underwent postsurgical reconstruction after @entity1697 resection using MSAPFs. To explore and locate the perforators, preoperative vascular ultrasound localization was used to find the MSAPs. The number and location of the perforators, length of the vascular pedicle, and thickness of the MSAPF were measured. Thirty-eight @entity1 who underwent reconstruction with a @entity4542 ( @entity4542 ) and 21 @entity1 who underwent reconstruction with an anterolateral thigh flap (ALTF) were selected for comparison. RESULTS: The number of MSAPs ranged from 1 to 4, and 52 perforators were found accurately using preoperative ultrasonic localization (92.86%). The distance from the perforator to the popliteal crease ranged from 6.2 to 17.1  cm (10.70    2.31  cm); the distance from the perforator to the midline of the back of the @entity291 ranged from 0.1 to 3.5  cm (1.83    0.81  cm); and the pedicle length ranged from 6.8 to 12.5  cm (10.14    1.51  cm). Compared with the @entity4542 , and ALTF, the thickness, @entity86 , and function of the MSAPF were similar to those of the @entity4542 but better than those of the ALTF. In appearance and function of the donor site, the MSAPF was similar to the ALTF, but better than the @entity4542 . CONCLUSION: The MSAPF is a good alternative for postsurgical @entity1697 because of its anatomic structural stability, suitable thickness, minimal donor-site scar, and ideal functional recovery after surgery. Preoperative vascular ultrasonic localization is a feasible and advantageous method for preoperative mapping of the MSAP because of its high accuracy.
