VARIATIONS OF THE PUBIC VASCULAR ANASTOMOSES IN BLACK SOUTH-AFRICANS

Variations of the arterial and venous pubic anastomoses (APA, VPA) wer e studied. Forty-four percent of the APA were replaced by an obturator artery arising from the inferior epigastric and 25% by an obturator a rtery arising from the external iliac. Seven percent of the VPA were r eplaced by a single obturator vein, 37% by the superior companion of a double obturator vein, and 2% by a double obturator vein. Black South African subjects exhibit a higher incidence of variations of the pubi c anastomoses than North American, European and Japanese populations.
