Interventions of the Mesenteric Arterial Circulation

The arteries of the mesenteric arterial circulation form an intricate system of vessels supplying the gastrointestinal tract (from the lower esophagus to the proximal rectum), the liver, spleen, and pancreas. These arteries are known for exhibiting significant inter-territorial collateralization with a rich network of anastomotic vessels. These arteries can be affected by a wide range of disorders in which endovascular management can play a significant role. Thrombolysis with recanalization using balloon angioplasty or stent placement can be used in the management of mesenteric arterial ischemia. Similarly, a few causes of acute as well as chronic gastrointestinal bleeding can also be effectively managed by endovascular embolization using a variety of agents depending on the anatomy and technical feasibility.
