The aim of this work was to specify the number of the external pudendal arteries and describe its origin as well as its relationship with the arch of the great saphenous vein. We dissected the external pudendal artery 72 times in 36 cadaveric subjects (29 men and 7 women) in the anatomy laboratory of the Faculty of Medicine and Odontostomatology in Bamako. There was a single external pudendal artery in 40 cases (55.56%). Two external pudendal arteries existed in 30 cases (41.67%). In 2 cases, three external pudendal arteries were present. The most common origins of the external pudendal artery were the common and superficial femoral arteries. In 1 case, the external pudendal artery originated from the quadricipital artery. The most common relationship of the external pudendal artery with the arch of the great saphenous vein was the sub-crossing of the latter by the single external pudendal artery. This report was noted in 32 cases (44.44%). In 7 cases (9.72%), the single external pudendal artery passed in front of the great saphenous vein and behind the lateral accessory saphenous vein. Most often there is only one EPA. When there are two EPA, they can be born in isolation or through a common core. The EPA contracts variable and close relationships with the butt of the GSV. Since lesions of the EPA can lead to sexual impotence, its origin and these relationships with the buttocks of GSV must be known by surgeons to avoid damaging it during surgical treatment of varicose veins of the pelvic limb.
CFA = Common femoral artery
EPA = External pudendal artery
GSV = Great saphenous vein
SFA = Superficial femoral artery
