Intestinal ischemia is a medical condition in which injury to the large or small intestine occurs due to not enough blood supply. [2] It can come on suddenly, known as acute intestinal ischemia, or gradually, known as chronic intestinal ischemia. [1]
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.
Chronic mesenteric ischemia requires surgical revascularization and treatment like stents, transaortic endarterectomy, or bypassing the arteries. Abdominal angina often has a one-year delay between symptoms and treatment, leading to complications like malnutrition or bowel infarction. Abdominal angina is more prevalent in females with a 3:1 ...
SMA syndrome is also known as Wilkie's syndrome, cast syndrome, mesenteric root syndrome, chronic duodenal ileus and intermittent arterio-mesenteric occlusion. [3] It is distinct from nutcracker syndrome, which is the entrapment of the left renal vein between the AA and the SMA, although it is possible to be diagnosed with both conditions. [4]
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 ...
About 20% of patients with acute ischemic colitis may develop a long-term complication known as chronic ischemic colitis. [8] Symptoms can include recurrent infections, bloody diarrhea, weight loss, and chronic abdominal pain. Chronic ischemic colitis is often treated with surgical removal of the chronically diseased portion of the bowel.
Reasons for resection of the bowel included: ulcerative colitis, Crohn's disease, injury, enteritis radiotherapy, mesenteric arterial infarction, and micro-vascular of unknown process. Five of the ...
Ischemia (loss of blood flow) to the affected portion of intestine. Depending on the location of the volvulus, symptoms may vary. For example, in patients with cecal volvulus, the predominant symptoms may be those of small bowel obstruction (nausea, vomiting and lack of stool or flatus), because the obstructing point is close to the ileocecal ...
