What does the left inferior phrenic artery supply?

What does the left inferior phrenic artery supply?

The inferior phrenic artery (IPA) is the most common source of extra-hepatic collateral blood supply for hepatocellular carcinoma (HCC) and frequently supplies HCCs located in the bare area of the liver.

Where is the inferior phrenic artery?

The inferior phrenic arteries usually arise between T12 and L2 vertebrae. They may arise separately from the front of the aorta, immediately above the celiac artery, or by a common trunk, which may spring either from the aorta or from the celiac artery.

What organs are supplied by the inferior phrenic arteries?

Inferior phrenic arteries (IPA) are double arteries which give off small branches to the diaphragm, liver, adrenal glands, esophagus, stomach, inferior vena cava, and retroperitoneum.

What does the inferior phrenic artery supply blood to?

the diaphragm
The inferior phrenic arteries are small vessels that may have various sites of origin. The purpose of these two arteries is to deliver blood to the diaphragm.

What is the most common origin of the inferior phrenic arteries?

The inferior phrenic arteries usually originate from the aorta or celiac artery, and less frequently from the renal, hepatic or left gastric arteries.

Where is the superior phrenic artery located?

The superior phrenic artery is a small paired artery that arises from the anterior aspect of the lower part of the thoracic aorta, just before it passes through the aortic hiatus of the diaphragm. The superior phrenic artery supplies the posterior part of the superior surface of the diaphragm.

Where does the left inferior phrenic artery come from?

The left inferior phrenic artery most commonly arises from the aorta. However, in a smaller number of cases it can be seen arising from the celiac trunk. The right artery has a higher degree of variation; it typically arises from either the aorta or the celiac trunk, but can also stem from the renal artery.

Where does the superior phrenic artery supply blood to?

The superior phrenic artery is a small paired artery that arises from the anterior aspect of the lower part of the thoracic aorta, just before it passes through the aortic hiatus of the diaphragm. The superior phrenic artery supplies the posterior part of the superior surface of the diaphragm.

Where does the left subclavian artery supply blood to?

The Left Subclavian Artery Ends at the outer border of the first rib where it becomes the axillary artery, which supplies blood to the axillary (armpit area) region of the body.

Where does the aorta pass through the diaphragm?

The aortic hiatus is one of the three major apertures through the diaphragm and lies at the level of T12. Strictly speaking, it is not a real aperture in the diaphragm, but an osseoaponeurotic opening between it and the vertebral column.

What does phrenic mean?

of or relating to the diaphragm
Definition of phrenic 1 : of or relating to the diaphragm. 2 : of or relating to the mind.

What does the superior phrenic artery supply?

What artery runs with the phrenic nerve?

The phrenic nerve is accompanied by the pericardiophrenic artery and superior phrenic vein throughout its course. The nerve, artery, and vein originate at the neck root and descend, parallel, along the lateral aspects of the pericardial sac, ultimately terminating at the superior aspect of the diaphragm.

What is the treatment for left left subclavian artery stenosis?

Symptomatic subclavian artery occlusive disease should be treated with endovascular stenting and angioplasty as first line management. If it is not successful then open surgery should be considered. Bypassing the carotid to the subclavian or to the axillary artery are both good treatment modalities.

What is left subclavian artery stenosis?

In subclavian stenosis, the artery is simply narrowed, leading to decreased blood flow beyond the area of blockage. When the subclavian blockage is severe, or if the artery is completely blocked, a condition called ‘subclavian steal’ can occur (Figure 4).

At which level does aorta perforate the diaphragm?

The aortic hiatus is one of the three major apertures through the diaphragm and lies at the level of T12.

Where does the left phrenic nerve pierce the diaphragm?

Left Phrenic Nerve Descends anterior to the left lung root. Crosses the aortic arch and bypasses the vagus nerve. Courses along the pericardium of the left ventricle. Pierces and innervates the inferior surface of the diaphragm.
