The superficial external pudendal artery (SEPA) axial-pattern flap.
An axial-pattern flap based on the superficial external pudendal vessels is described. Its anatomy has been studied in 12 cadavers and the flap has been used clinically in 6 patients. The flap is very mobile and can be rotated through almost 180 degrees on either side. Immobilisation is less troublesome when the flap is used on the hand. A bilateral SEPA flap is also described.
