ABSTRACT
Objective@#To explore the feasibility of preoperative designing for anterolateral femoral flap using three longitudinal and five transversal strategy.@*Methods@#From September 2015 to January 2017, 71 patients (73 pieces) were treated using anterolateral thigh flap in the Affiliated Hospital of Zunyi Medical University. There were 48 males and 23 females, with the age of (36±18) years. The three longitudinal and five transversal designing was performed before operation. Portable Doppler ultrasound was used to detect the piercing-out position (P point) of perforators in Ⅰ, Ⅱ, Ⅲ, Ⅳ areas. The diameter, direction and length (lower subcutaneous segment of perforators) of perforators after leaving piercing-out position were observed during the operation. The piercing-in positions on superficial fascia and the dermis were observed.@*Results@#The data of 71 adults (73 legs) were evaluated. Before and during the operation, all the perforations were found in Ⅰ, Ⅱ, Ⅲ and Ⅳ areas. The number of perforators in region Ⅰ was 1.32±0.33, with the diameter of perforator at the piercing-out position was (0.79±0.13) mm. The length of subfascial segment of perforators was (1.54±0.97) cm, and the direction was oblique superolateral. The number of perforators in Ⅱ region was 1.21±0.53, with the diameter of perforator at the piercing-out position was (0.63±0.13) mm. The length of subfascial segment of perforators was (2.25±0.54) cm, and the direction was oblique inferoanterior. The distance form piercing-in position to line L was (0.84±0.42) cm. The number of perforators in the Ⅲ area was 2.22±0.49, with the diameter of perforators at the piercing-out position was (0.53±0.12) mm. The length of subfascial segment of perforator was (1.96±0.44) cm, and the direction was oblique inferoanterior. The distance between piercing-in positions to line L was (0.74±0.51) cm. The number of perforators in region Ⅳ was 1.41±0.72, with the length of subfascial segment of perforators was (1.22±0.45) cm and the direction was oblique inferolateral. There were 27 cases with oblique perforators, accounting for 37% of the total number of thighs.@*Conclusions@#This three longitudinal and five transversal designing is helpful to detect the expenditure point in the anterolateral femoral region, and is assistant to skin flap designing.
