From the Guidelines
The marginal artery of Drummond originates as an anastomotic vessel connecting branches of the superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) along the inner border of the colon. This important collateral pathway forms when the marginal branches of the right, middle, and left colic arteries join together to create a continuous arterial arcade that runs parallel to the mesenteric border of the large intestine. The artery was named after Sir David Drummond, a British physician who described it in the early 20th century. This vascular connection is clinically significant because it provides alternative blood flow to the colon when either the SMA or IMA becomes occluded or compromised, as noted in the context of mesenteric ischemia etiologies and pathophysiology 1. Key aspects of its formation and function include:
- The marginal branches of the colic arteries joining to form a continuous arcade
- The artery's role in providing collateral circulation to the colon
- Its clinical significance in maintaining intestinal viability during vascular occlusive events or surgical procedures involving major mesenteric vessels. The marginal artery of Drummond is particularly important at the splenic flexure, where it forms a critical anastomosis known as the "point of Griffiths" between the SMA and IMA territories, highlighting its crucial role in intestinal blood supply 1.
From the Research
Origin of the Marginal Artery of Drummond
The marginal artery of Drummond is a critical blood vessel that plays a significant role in the collateral circulation between the superior mesenteric artery and the inferior mesenteric artery. The origin of this artery is closely related to the inferior mesenteric artery.
- The marginal artery of Drummond originates from the inferior mesenteric artery, which is one of the three main arteries that supply blood to the intestines 2, 3, 4, 5.
- It is an important anastomotic channel that connects the superior mesenteric artery and the inferior mesenteric artery, providing a collateral blood supply to the colon 2, 4.
- The marginal artery of Drummond is also known as the "wandering artery of Drummond" due to its variable course and anastomoses with other arteries 3.
- The artery is a vital structure that helps to maintain blood flow to the colon in cases of occlusion or stenosis of the superior mesenteric artery or inferior mesenteric artery 2, 4, 5.
Clinical Significance
The marginal artery of Drummond has significant clinical implications, particularly in the management of mesenteric ischemia and colorectal surgery.
- The artery's presence and patency can affect the outcome of surgical procedures, such as resections and anastomoses 4.
- The marginal artery of Drummond can also be a source of bleeding, as seen in cases of aneurysm rupture 6.
- Evaluation of the marginal artery of Drummond and its anastomoses is essential in preoperative planning to minimize the risk of complications and ensure optimal outcomes 4.
