Theinferior suprarenal artery is a paired artery that supplies theadrenal gland. It usually originates at the trunk of therenal artery before its terminal division, but with many common variations. It supplies theadrenal glandparenchyma, theureter, and the surrounding cellular tissue and muscles.
The inferior suprarenal artery usually originates at the trunk of therenal artery.[1][2] This is usually on its superior surface before its terminal division.[1] It enters theparenchyma of theadrenal gland.[1]
Variations in the interior suprarenal artery are common.[1][3] It usually originates from therenal artery before its final divisions, but may also originate as a final division or after the final divisions.[1] More rarely, it may originate directly from theaorta.[1] It may give off a small branch to thekidney.[1]
There may be two or three inferior suprarenal arteries in some people.[1] Its diameter changes significantly with age.[4]
The inferior suprarenal artery supplies theadrenal gland (suprarenal gland).[1] They also supply theureter and some surrounding tissue andskeletal muscle.[citation needed]
The inferior suprarenal artery may be affected by ananeurysm.[5] It may be assessed usingDoppler ultrasound.[6]
The inferior suprarenal artery may also be known as the inferior adrenal artery.[6]
