Mesenteric ischemia refers to a significant reduction or complete blockage of blood flow to the intestinal tract, resulting in inadequate oxygen delivery to bowel tissues. This condition presents in two major forms: acute mesenteric ischemia, which is commonly triggered by embolic or thrombotic events, and chronic mesenteric ischemia, more often associated with progressive atherosclerotic narrowing of the mesenteric arteries. Clinically, patients may experience intense abdominal pain—often out of proportion to physical findings—accompanied by nausea and vomiting. In chronic cases, symptoms such as postprandial abdominal pain and unintended weight loss are characteristic, largely due to fear of eating and subsequent discomfort.

Timely recognition of mesenteric ischemia is imperative, as delays may lead to bowel infarction and potentially fatal outcomes. Diagnostic evaluation generally involves advanced imaging modalities, including CT angiography, MR angiography, and duplex ultrasonography, all of which enable visualization of blood flow and identification of vascular obstructions. Therapeutic interventions range from endovascular procedures (such as angioplasty and stenting) and surgical revascularization to supportive medical management, tailored to disease severity and underlying etiology. Ultimately, early detection and prompt management are essential for restoring intestinal perfusion, minimizing complications, and improving overall patient prognosis.
