Ischemic colitis (also spelled ischaemic colitis) is a medical condition in which inflammation and injury of the large intestine result from inadequate blood supply . Although uncommon in the general population, ischemic colitis occurs with greater frequency in the elderly, and is the most common form of bowel ischemia .
Watershed area is the medical term referring to regions of the body, [1] that receive dual blood supply from the most distal branches of two large arteries, such as the splenic flexure of the large intestine. The term refers metaphorically to a geological watershed, or drainage divide, which separates adjacent drainage basins. For example, the ...
Although uncommon in the general population, ischemic colitis occurs with greater frequency in the elderly, and is the most common form of bowel ischemia. [ 43 ] [ 44 ] [ 45 ] Causes of the reduced blood flow can include changes in the systemic circulation (e.g. low blood pressure ), or local factors such as constriction of blood vessels or a ...
Ischemic colitis is kind of like a stroke or heart attack that affects your gut instead of the brain or heart, explains Arun Swaminath, MD, director of the Inflammatory Bowel Disease Program at ...
The splenic flexure is a watershed region as it receives dual blood supply from the terminal branches of the superior mesenteric artery and the inferior mesenteric artery, thus making it prone to ischemic damage in cases of low blood pressure because it does not have its own primary source of blood.
Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis. [4] Bowel obstruction is most often caused by intestinal adhesions, which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis, hepatitis, and inflammatory bowel disease.
One study found that the medication tulisokibart may help people with moderate to severe ulcerative colitis achieve clinical remission. Ulcerative colitis is a chronic condition characterized by ...
Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
