Irrigación de las cápsulas adrenales en humanos

the adrenal glands also known as suprarenal glands, are two small structures located on the suprahiliar border of the kidney. they belong to the endocrine system. the anatomical books describe for them a classic vascular pattern, nevertheless they really have important variations in origin and branching pattern. in this work we employed human fetuses, carefully dissected, vinyl perfused. the sample was constituted by 66 adrenal glands. after a very careful observation of the serie we found that the classic pattern was seen in 15.30 % of the sample. superior suprarenal artery was localized at the abdominal aorta in 46.15 %, the medial artery was arising from aorta in 53.85.%, and the inferior suprarenal artery was also found taking origin at abdominal aorta,on its own in 61.54 % , and in 12.31 % together with the renal artery. we also notice that the vascular approach to right adrenal gland is different from that for the left gland in 56.25 %.
