How does superior mesenteric artery embolism occur?

Superior mesenteric artery embolism is mainly related to factors such as superior mesenteric artery atherosclerosis, cardiac embolus detachment and malignant tumors.

1. Superior mesenteric artery

atherosclerosis is lipid accumulation, fibrous tissue hyperplasia and calcinosis in the inner wall of the artery. Atherosclerosis plaques can block the superior mesenteric artery and cause superior mesenteric artery embolism.

2. Cardiac embolus detachment.

Visceral diseases such as atrial fibrillation and endocarditis may lead to thrombosis in the heart. Thrombus detachment enters the superior mesenteric artery with blood flow and causes superior mesenteric artery embolism.

3. Malignant tumors

can cause blood to be in a hypercoagulable state, causing thrombosis in the superior mesenteric artery. Thrombus detachment can cause superior mesenteric artery embolism.
