Gastrointestinal - Ischemic Bowel Disease
In this episode, we review ischemic bowel disease, a life-threatening condition caused by insufficient blood flow to the intestines. We break down the spectrum of disease—including ischemic colitis, acute mesenteric ischemia, and chronic mesenteric ischemia—and discuss key risk factors such as vascular disease and atrial fibrillation. The episode highlights the classic presentation of severe abdominal pain out of proportion to exam, the critical role of CT angiography, and the need for emergent surgical consultation.
