The arterial circulation of the left suprarenal gland

Abstract

The findings in a study of the general circulation of the suprarenal glands in 25 cases, and particularly of the left glands in 50 cases, are presented. The vessels arose from three pedicles: superior, middle and inferior. The inferior pedicle was the most irregular, with a frequent contribution from the gonadal artery to the inferior part of the gland; this artery should not be regarded as merely an accessory vessel. On the left side an inconstant posterior pedicle, separate from the others, was found in 26% of cases. Two forms of gonadal artery supplying the gland (8%) are described, an upper origin type at the renal artery level and an aberrant type.
