RESUMEN
This study was performed to measure the distance of perforating point for superficial and deep external pudendal arteries from pubic tubercle and anterior superior iliac spine, patterns of arterial distribution, and external diameter. Fifty three thighs from 27 Korean cadavers (13 males / 14 females), clinically normal and without deformity, were dissected and standard points were determined as follows: point of pubic tubercle (A) and point of anterior superior iliac spine (B). The obtained results were as follows: 1. The external pudendal artery branched from femoral artery was distributed in the medial thigh. Superficial external pudendal artery is located above the saphenous opening and Deep external pudendal artery is located below the saphenous opening. 2. The saphenous opening were 4.7+/-1.2 cm apart from point A and 10.1+/-1.3 cm from B. 3. The superficial external pudendal artery were 5.2+/-1.2 cm apart from A and 8.9+/-2.1 cm from B. 4. The deep external pudendal artery were 4.7+/-1.1 cm apart from A and 10.8+/-1.3 cm from B. Consequently, the patterns of distribution of superficial and deep external pudendal arteries, obtained in this study, will provide useful anatomical backgrounds for the external pudendal flap surgery in korean.
