What do the inferior phrenic arteries supply?
The inferior phrenic arteries (IPAs) are paired branches of the abdominal aorta/celiac trunk supplying the diaphragm. Their importance lies with the fact that the right inferior phrenic artery is the most common extrahepatic arterial supply of a hepatocellular carcinoma.
What does inferior phrenic artery come off?
Function. The inferior phrenic arteries supply the diaphragm. Each of the smaller vessels give off superior suprarenal branches to the suprarenal gland of its own side. The spleen and the liver also receive a few twigs from the left and right vessels respectively.
Where does the inferior phrenic artery go?
The left inferior phrenic artery passes behind the esophagus and then along the left margin of the esophageal hiatus. Both arteries reach the posterior margin of the central tendon of the diaphragm, where they split into their respective ascending (medial) and descending (lateral) branches.
What does the superior phrenic artery do?
The superior phrenic arteries mainly supply the diaphragm, but also participate in providing the suprarenal glands.
Where does inferior suprarenal arteries come from?
The inferior suprarenal arteries usually (variations are common ) originate at the trunk of the renal artery before its terminal division, and usually present substantially different diameters corresponding to the age variable.
What is the most common origin of the inferior phrenic arteries?
aorta
The inferior phrenic arteries usually originate from the aorta or celiac artery, and less frequently from the renal, hepatic or left gastric arteries.
Where does the right inferior phrenic vein drain?
diaphragm
The Inferior Phrenic Veins drain the diaphragm and follow the course of the inferior phrenic arteries. The right ends in the inferior vena cava.
What supplies superior phrenic artery?
Superior phrenic artery
| Origin | Thoracic aorta |
|---|---|
| Supply | Posterior aspect of the superior surface of the diaphragm |
What does the word suprarenal mean in medical terms?
adrenal

What does suprarenal artery supply?
The superior adrenal (suprarenal) arteries are a group of arteries that together form one of the three adrenal arteries that supply the adrenal gland. There are usually numerous small arteries arising from the inferior phrenic artery.
What is inferior phrenic artery?
What does the inferior phrenic vein do?
The Inferior Phrenic Veins drain the diaphragm and follow the course of the inferior phrenic arteries. The right ends in the inferior vena cava.
Where does the inferior phrenic artery come from?
Inferior phrenic artery (Arteria phrenica inferior) The inferior phrenic artery is a paired vessel that arises from the abdominal aorta. The left and right inferior phrenic arteries emerge immediately below the diaphragm, being the first set of paired branches of the abdominal aorta.
Where does the right phrenic pass behind the inferior vena cava?
The right phrenic passes behind the inferior vena cava, and along the right side of the foramen which transmits that vein. Near the back part of the central tendon each vessel divides into a medial and a lateral branch. The medial branch curves forward, and anastomoses with its fellow of the opposite side,…
Where does the left phrenic artery pass behind the esophagus?
The left phrenic passes behind the esophagus, and runs forward on the left side of the esophageal hiatus. The right phrenic passes behind the inferior vena cava, and along the right side of the foramen which transmits that vein. Near the back part of the central tendon each vessel divides into a medial and a lateral branch.
