The correlation of the perforators and the accessory saphenous vein in a profunda femoris artery perforator flap for additional venous anastomosis: A cadaveric study and clinical application.

Anatomical study confirmed that the accessory saphenous vein did exist in all specimens and it could be included in the PAP flap with sufficient length and relatively large diameter. Although further clinical investigation will be required to confirm its efficacy, a PAP flap including the accessory saphenous vein may decrease the chances of flap congestion.
