Multiple variations in the paired arteries of the abdominal aorta

Abstract

Variations in the origin of arteries in the abdomen are very common. The arteries that show frequent variations include the celiac trunk, renal arteries, and gonadal arteries. We observed multiple variations in a 45-year-old male cadaver. The variations found on the left side were: one accessory renal artery, two testicular arteries, and middle suprarenal and inferior phrenic arteries that branched from the celiac trunk. On the right side, the inferior phrenic and middle suprarenal arteries arose from the right renal artery.

Abdominal Aorta and Its Branches: Morphometry - Variations In Autopsy Cases

“…Median sacral artery (MSA) is a small branch that arises from the posterior aspect of the aorta a little above its bifurcation (1,3). Variations in AA and its branches are frequently observed and they occur due to embryological developmental changes (4)(5)(6). For example IPA and CT may originate from AA as a single common trunk or a fifth pair of LA may occasionally arise from the MSA (1).…”

“…Variations of GA should be noted while performing surgical and radiological procedures on kidneys (4). IPA is the most common source of extrahepatic collateral blood supply for hepatocellular carcinoma (HCC) and frequently supplies HCCs located in the bare area of the liver.…”

Variant anatomy of the celiac trunk –review of literature with a case report

“…bifurcation 10,11,13-18,21-23 , quadrifurcation 6,10,13,[15][16][17]19,20,22,[24][25][26] , pentafurcation 5,9,10,13,15,20,25,[27][28][29][30][31][32] , hexafurcation 13 , heptafurcation 33 and even absence 4,8,13,14,[16][17][18] of the trunk. Generally additional branches other than the normal branches are referred to as collaterals 5, 21, 27, 29, 32, 33 .…”

“…Generally additional branches other than the normal branches are referred to as collaterals 5, 21, 27, 29, 32, 33 . Reported collaterals of the CT include the inferior phrenic, aberrant right hepatic, gastroduodenal, middle colic, dorsal pancreatic, left superior suprarenal, left middle suprarenal, duodenal or ileal arteries 5,6,9,10,13,15,16,19,20,[24][25][26][27][28][29][30][31][32][33] . Presence of additional arteries may provide collateral circulation which may be important during liver transplant, laparoscopic surgeries, and radiological abdominal interventions in day to day clinical practice 29 .…”

Arterias Renales Múltiples

“…La literatura es rica en presentaciones de casos con más de una arteria renal por lado (Bulic et al, 1996;Loukas et al, 2005;Tanyeli et al, 2006;Deepthinath, 2006, entre otros).…”
