Intestinal ischemia and infarction?
by

1 Answer

Answer :

DefinitionIntestinal ischemia and infarction is damage to (ischemia) or death of (infarction) part of the intestine due to a decrease in its blood supply.Alternative NamesIntestinal necrosis; Ischemic bowel; Dead bowel; Dead gutCauses, incidence, and risk factorsThere are several possible causes of intestinal ischemia and infarction.Hernia: If the intestine moves into the wrong place or becomes tangled, this can lead to intestinal ischemia.Adhesions: The intestine may become trapped in scar tissue from past surgery (adhesions). This can lead to ischemia if left untreated.Embolus: A blood clot from the heart or main blood vessels may travel through the bloodstream and block one of the arteries supplying the intestine. Patients with previous heart attacks or with arrhythmias, such as atrial
