What's Behind Mesenteric Venous Thrombosis?
Published: Jul 05, 2024
Mesenteric venous thrombosis is a condition where a blood clot forms in the veins that drain blood from the intestines. It can cause a sudden decrease in blood flow to the intestines, leading to serious complications.
What is Mesenteric Venous Thrombosis?
Mesenteric venous thrombosis occurs when a clot forms in the veins responsible for draining blood from the intestines. This condition can lead to reduced blood flow, causing the intestines to suffer from a lack of oxygen and nutrients. If untreated, it might result in severe bowel damage or infarction. The condition can present itself suddenly or develop over time, and it affects the small intestine more often than the colon.
Common Risk Factors
Several factors can increase the risk of developing mesenteric venous thrombosis. These include inflammatory conditions like pancreatitis or inflammatory bowel disease and certain inherited blood disorders that make the blood more prone to clotting. Other risks include abdominal surgery, obesity surgery, and even certain infections like COVID-19. Older age and a history of blood clots also contribute to higher risk.
Symptoms to Watch For
Symptoms of mesenteric venous thrombosis can range from mild to severe. Initially, one might experience dull abdominal pain, nausea, and vomiting. Over time, if the condition worsens, symptoms may include more intense pain, abdominal swelling, and even signs of intestinal blockage. In chronic cases, symptoms might be less obvious, leading to complications like portal hypertension.
