collateral artery

These collateral arteries carry blood which has already be oxygenated by the lungs, so are of little use in helping the body to get oxygen.

It anastomoses with the middle collateral artery.

In front of the medial epicondyle it anastomoses with the superior and Inferior ulnar collateral arteries.

Anconeus is supplied by the middle collateral artery from the profunda brachii artery.

The inferior ulnar collateral artery (anastomotica magna artery) arises about 5 cm.

Major aortopulmonary collateral arteries come from the systemic circulation, because of this they will often have higher pressure than normal found in the lungs leading to pulmonary hypertension.

The medial collateral artery (also known as the middle collateral artery) is a branch of deep brachial artery.

This type of microangiography uses monochromatic synchrotron radiation and a high-definition video system to provide an image of small collateral arteries with a diameter less than 100 m.

Major aortopulmonary collateral arteries (or MAPCAs) are arteries that develop to supply blood to the lungs when native pulmonary circulation is underdeveloped.

The radial collateral artery (another term for the anterior descending branch of the profunda brachii artery) is a branch of the deep brachial artery.

It is perforated by the ulnar nerve, the superior ulnar collateral artery, and the posterior branch of the inferior ulnar collateral artery.

Major aortopulmonary collateral arteries (MAPCAs) develop early in embryonic life but regress as the normal pulmonary arteries (vessels that will supply deoxygenated blood to the lungs) develop.

Cerebral collateral circulation Blood flow to the brain is maintained via a network of collateral arteries that anastomose in the circle of Willis, which lies at the base of the brain.

The attractiveness of protein therapy is that large amounts of the therapeutic agent can be injected into the ischemic area of interest, to pharmacologically start the process of blood vessel growth and collateral arteries formation.

The superior ulnar collateral artery (inferior profunda artery), of small size, arises from the brachial a little below the middle of the arm; it frequently springs from the upper part of the a. profunda brachii.

This can lead to hypoxic cell death (infarction) and amplify the original damage from the ischemia; however, the penumbra area may remain viable for several hours after an ischemic event due to the collateral arteries that supply the penumbral zone.
