1. ascending & decending aorta
2. celiac artery: splenic artery, common hepatic artery, left gastric artery
3. superior mesenteric artery
4. right & left renal arteries
5. inferior mesenteric artery
6. right & left common iliacs
7. right & left internal iliacs

1. lies slightly to the left of the midline
2. can be viewed in trans & long approaches
3. tapers from the diaphragm to the iliac bifurcation
4. supplies the lower circulatory system
5. measures: men/2.3 & women/1.9

1. can be viewed in trans
2. aka celiac axis/celiac trunk
3. has a low resistance Doppler signal
4. 1st branch of the aorta

1. SPLENIC - spleen, pancreas, stomach
2. CHA - liver
3. LT. GASTRIC - stomach

If the celiac artery occludes, collaterization occurs thru?

If the celiac artery is occluded what happens to the splenic & CHA flow?

The pancreaticoduodental arterial arcade.

It may appear with normal flow.

1. torutuous in the distal segment
2. courses along posterosuperior margin of the pancreas body & tail
3. terminates by the splitting into lots of branches in the hilum of the spleen
4. the distal portion of the splenic artery can be viewed thru the spleen from a left lateral approach
5. flow is usually turbulent because of tortuosity

1. gives rise to the gastroduodenal artery seen at the anterosuperior border of the pancreas
2. beyond the gastroduodenal the CHA becomes the proper hepatic artery
3. enters liver and bifurcates into the right & left hepatic arteries

1. 2nd branch of the aorta
2. lies just below the celiac artery
3. parallel to aorta

1. the hepatic arteries
2. the portal veins (80%)

1. jejunal & ileal arteries
2. middle colic artery
3. right colic artery
4. ileocolic artery

1. jejunum
2. ileum
3. cecum
4. ascending colon/small intestine
5. transverse colon/1st part of the large intestine
6. portions of the duodenum & pancreatic head

1. supply the kidney
2. branch off the lateral aspect of the aorta, below SMA
3. right renal is usually higher & appears to branch off 1st
4. courses behind the IVC to the right kidney
5. both renals are behind the renal veins

Where does the right renal artery arise?

Where does the left renal artery arise?

1. anterolateral from the aorta, passes posterior to the IVC
2. posterolateral from the aorta, follows to the renal hilum

Almost 1/3 of the kidneys are supplied by??

Can you have duplicate or accessory renal arteries?

If so, where do they enter the kidney?

1. two or more arteries arising from the aorta
2. yes
3. they enter the kidney thru the hilum or the pole of the kidney

The origin of the renal arteries are best view in what approach?

Which renal can be followed to the kidney?

What instructions should we give the patient prior to study?

in the tranverse midline approach

the right

fasting and toperform test in the a.m. for less gas formation

Which renal artery if more difficult to see?

And is better seen in what position?

left renal artery

from a more posterolateral position

What position do you scan large & obese patients?

This ultrasound image is sometimes called?

flank- left lateral decubius position

the "banana peel" view

What type of Doppler signals do the renal arteries have?

Why?

What type of Doppler signals are throughout the entire renal vessels?

low resistence

because of low vascular resistence in the renal beds

low resistence
