ANATOMIC STUDY OF THE EXTERNAL PUDENAL VESSELS TO THE ANTERIOR SCROTAL REGION

The aim of this study uas omv of the external pudendal vessels as they supply the anterior scrotal region, Twenty cadavers were dissected an d a catheter was used to inject India ink into the external pudendal a rteries. The entire anterior scrotal region was dyed in all these case s, in one case, the dye extended beyond the scrotal raphe, staining th e opposite scrotum. The skin of the region proximal to the penis on th e same side was also stained; in ten cadavers, in 11 the skin of the s uperior-medial homolateral thigh displayed dye, The external pudendal artery was a single vessel in 55% of cases, double in 30% and with a c ommon trunk with the superficial inferior epigastric artery in 15%. Th e external pudendal vein as single in 45% and double in 55%. The arter ial diameter ranged from 1.55 to 2.90 mm for the single artery, 1.9 to 3.00 mm for the double artery, and 3.50 to 4.00 mm for the common tru nk. The diameter both of the single and the double vein ranged from 1. 56 to 3.70 mm, The pedicle length from the femoral vessels to the scro tal region ranged from 7.2 to 9.5 cm. The diameter, the length of the pedicle vessels, and their constant the anterior scrotal region may be used as a donor site for a microsurgical flap.
