Mesenteric ischemia occurs when any of the mesenteric arteries, which supply blood to the intestines, are constricted. Because cells require blood for oxygen and nutrients, a lack of blood can cause cells to die. This is called ischemia. Ischemia in the small intestine interferes with digestion and can cause severe abdominal pain.
Mesenteric Ischemia: What You Need to Know
Arteries are quite often narrowed or blocked due to atherosclerosis, when fat, cholesterol and other deposits collect on the inside of the artery walls.
Other causes may include low blood pressure, celiac compression syndrome, coagulation disorders and blockage of arteries in the intestine.
Your doctor's goal is to surgically remove or bypass the blockage and allow blood to flow to the intestinal tissues.
