Its function is to serve as a communicating arcade between the superior and inferior mesenteric arterial territories, providing collateral blood flow to the colon and helping maintain perfusion when one mesenteric artery may be compromised.
What conditions may affect the marginal artery of Drummond?
Mesenteric ischemia and occlusive vascular disease may be associated with disruption of this arcade, and its integrity is a critical consideration during surgical procedures such as aortic surgery or colonic resection.
