**3.1 Acute mesenteric ischemia**

The most common symptom of AMI associated with arterial thromboembolic disease is the sudden onset of abdominal pain. Lack of collateral flow to the visceral organs leads to a more dramatic presentation in AMI, with severe, rapid clinical deterioration. Nausea, vomiting, diarrhea, emptying symptoms, and abdominal distention can also occur. Patients with NOMI or MVT typically present with a slower clinical course. Frequently, patients with NOMI are critically ill, hospitalized, intubated patients who experience a sudden deterioration in their clinical condition.
