Overview
Abdominal angina is an unusual cause of intermittent abdominal pain. Arterial vascular insufficiency is the cause of abdominal angina.The term angina is used because the pain develops only after eating, due to diminshed arterial supply that's needed to meet the increased demands to support digestion [1]. It's due to reduced mesenteric blood flow, reduced oxygen content of red blood cells distributed via the mesenteric arterial circulation, or mesenteric venous stasis, any of which can lead to tissue hypoxia and ischemic injury[1]
Pathophysiology
- The pathophysiology is similar to that seen in angina pectoris and intermittent claudication.
- Abdominal angina occurs due to narrowing of the mesenteric vessels that causes decreased blood flow.[2]
- Atherosclerotic vascular disease at ostia of the mesenteric vessels is the most common cause of abdominal angina . Superior mesenteric artery occlusion is often found in patients presenting symptomatic occlusive mesenteric ischemia. Patients with abdominal angina are unable to increase flow in the mesenteric vessels in response to eating that's why they develop postprandial pain.[2]
