|The renal arteries arise from the aorta: ||MpLaterally
From the lateral aspect. The right renal artery is usually anterolateral, the left renal usually posterolateral.|
|Because of the location of the IVC, the left renal vein: ||Crosses anterior to the aorta inferior to the left renal artery.
The AO is left of ML, while the IVC is RT. The left side of the abd must have venous flow across the AO. The FT RV is ant to the AO, usually just inf to the level of the RA.|
|In a cross section of the AO and surrounding regions, the vein that is visualized superficial to the AO and the origins of the R&L renal arteries and deep to the SMA is the: ||The left renal vein
The left renal vein travels anterior to the AO to reach across to the IVC|
|The superior mesenteric artery typically originates from the: ||Aorta between the celiac trunk and the renal arteries.
The SMA may originate from the celiac trunk.|
|The SVC is formed by the junction of the ||Right and left brachiocephalic veins.
Also called the right and left innominate veins. The brachiocephalic vein turns into the subclavian vein at the junction of the IJV.|
|The portal vein is formed by the junction of the: ||Superior mesenteric and splenic veins.
The inferior mesenteric vein joins with the splenic vein, which in turn joins with the superior mesenteric vein to become the portal vein.|
|A useful landmark for locating the renal arteries is the: ||Superior mesenteric artery
The renal artery origins lie just distal to the origin of the SMA from the aorta. The left renal vein, which passes across to the IVC under the prox SMA and lies ant and a bit dist to the RA's, can also be a landmark.|
|The splenic, common hepatic, and left gastric arteries arise from this abdominal artery: ||Celiac trunk
The celiac is the first major branch of the abdominal aorta. It divides into the common hepatic, splenic, and left gastric arteries.|
|The most common anatomic variation of the renal arteries is: ||Multiple renal arteries.|
|Which artery supplies the small intestine, right colon, and transverse colon? ||SMA
The SMA is second major branch of abd AO. Arises 1 cn below origin of Celiac trunk. Major branches of the SMA include the inf. pancreaticoduodenal art., jejunal and ileal branches, ileocolic, rt colic and middle colic arteries.|
|What organs do the Inf. Mesenteric Artery feed? ||The IMA feeds the left third of the trv colon, the sigmoid colon, and part of the rectum. IMA is usually much smaller thant the SMA.|
|Where does the IMA arise? ||The IMA arises on the left ventral aspect of the abd AO a few centimeters before the AO bif.|
|What are the major branches of the IMA? ||Its major branches include the left colic artery, sigmoid branches and superior rectal artery.|
|Another name for the hypogastric artery is: ||Internal iliac artery.|
|Which artery is the left branch of the celiac trunk? ||Splenic artery|
|What is the name of the tiny intra-renal branches that arise from the interlobar arteries at right angles and course above the renal pyramids? ||Arcuate arteries.
The arcuate arteries arise at right angles from the interlobar arteries and course on top of the renal pyramids. Within the renal cortex, the arcuate arteries give rise to the radially oriented interlobular arteries.|
|Describe the renal vasculature from renal artery to interlobar arteries. ||The main renal artery divides at the hilum of the kidney into segmental renal arteries. These in turn give rise to the interlobar arteries, which course alongside the renal pyramids|
