Abstract:
:The frequency with which the gonadal arteries follow a recurrent course, upwards and arching over the renal veins before descending to the gonads, is recorded for the South African Negro. The gonadal arteries follow such a course on the left side in 17, 2% and on the right side in 22% of cases. This incidence for arched left sided arteries is comparable to that recorded in other studies, but the frequency for arched right sided arteries in the South African Negro appears to be higher. Recognition of arching gonadal arteries is of importance to the vascular surgeon and urologist.
