Chronic Mesenteric Ischemia

Chronic Mesenteric Ischemia is a condition that affects the blood vessels supplying the intestines, mainly the arteries that bring oxygen-rich blood to the digestive system. It occurs when these arteries become narrowed or blocked, usually due to atherosclerosis, which reduces blood flow. This decreased blood supply can cause abdominal pain, especially after eating, because the intestines need more blood to digest food. People with this condition may experience weight loss and fear of eating due to pain. The main health impact is poor digestion and nutrient absorption, which can lead to serious complications if untreated.

Chronic Mesenteric Ischemia is a syndrome characterized by insufficient blood flow through the mesenteric arteries to meet the metabolic demands of the intestines, typically caused by atherosclerotic stenosis or occlusion of two or more major vessels (celiac artery, superior mesenteric artery, inferior mesenteric artery). This results in postprandial abdominal pain, often described as dull and crampy, leading to food aversion and weight loss. The condition reflects a state of chronic intestinal hypoperfusion, which can progress to bowel infarction if untreated. It is most common in elderly patients with cardiovascular risk factors such as smoking, hypertension, and hyperlipidemia. Diagnosis is clinically significant because it requires timely intervention to prevent ischemic bowel complications.
