What is the marginal artery?
Background. The marginal artery of Drummond (MA) is an anatomically variable blood vessel that forms a major anastomotic network between the superior and inferior mesenteric arteries. It vascularizes the transverse and descending colons and is a major contributor to the collateral circulation of left-colic structures.
What is marginal vein?
The marginal vein, an abnormal superficial vein of the lateral lower limb, is a remnant of primitive embryonic vessels that have failed to regress. According to the extent, topography and sites of connection with the deep veins, five types have been distinguished by Weber.
What may occur if there was a blockage to a coronary artery?
When one or more of the coronary arteries suddenly becomes completely blocked, a heart attack (injury to the heart muscle) may occur. If the blockage occurs more slowly, the heart muscle may develop small collateral blood vessels (or detours) for other coronary arteries to reroute the blood flow, and angina occurs.
Why is it called the marginal artery?
The marginal artery of Drummond is named after British pathologist and anatomist Sir David Drummond (1852–1932) who found that even though the three main colic arteries were surgically tied off, contrast medium injected into the ileocolic artery still passed to the sigmoidal branches 4,5.
