The oblique branch of lateral circumflex femoral artery: alternative vascular pedicle for pedicled anterolateral thigh flaps / 中华整形外科杂志

ABSTRACT

Objective@#To explore the feasibility and technical points of soft tissue defect reconstruction using the pedicled anterolateral thigh flap based on perforating vessels from the lateral circumflex femoral artery oblique branch.@*Methods@#Between November 2009 and April 2019, 27 pedicled anterolateral thigh flaps were performed to repair the wound of trunk and lower extremity, based on perforating vessels from the lateral circumflex femoral artery oblique branch. 16 flaps were proximally based and 11 were distally based.@*Results@#The proximally based flap ranged from 15 cm×8 cm to 32 cm×12 cm. The mean length of the pedicle was 8.2 cm. The distally based flap ranged from 9 cm×7 cm to 24 cm×8 cm. The mean length of the pedicle was 18.6 cm. All flaps survived after surgery. Venous congestion occurred in one flap and relieved in five days.@*Conclusions@#With oblique branch as the pedicle, the vascular dissection was easy and donor site morbidity was minimized while harvesting the proximally based anterolateral thigh flaps; long pedicle could be obtained, and the reconstructive sphere was extended when using the distally based anterolateral thigh flaps.
