What causes mesenteric arterial thrombosis?

Atheroslerosis: Serious often lethal condition if early diagnosis and intervention is not done, most common cause is atherosclerosis, slow flow state will also causes it, as ICU patients in shock due to various conditions.

3 major factors: Condition of the artery (caliber, plaque, injury, inflammation...) viscosity of the blood (hydration, tobacco, blood element derangement...) and the force of the blood flow (stasis, poor heart functions...) are the main factors leading to mesentary arterial thrombosis. It can happen in association to an embolic event.

Rupture plaque: Typically an atherosclerotic plaque/ hardening in the mesenteric artery that cracks/rupture causing acute clot or thrombosis inside the artery. Usually occurs in chronic smokers, sometimes with diabetics , hypertensive or high cholesterol patients. Unfortunately, mortality in these cases is very high / at least 50% because of associated severe and extensive bowel ischemia and gangrene.
