What is Ischaemic colitis?

Ischemic colitis occurs when blood flow to part of the large intestine is temporarily reduced. This segment of the large intestine is called the colon. This reduced blood flow may be caused by narrowing of the blood vessels supplying the colon. It also may be due to reduced blood flow caused by low blood pressure.


How is ischemic colitis treated?

Antibiotics, to prevent infections. Intravenous fluids, if you are dehydrated. Treatment for any underlying medical condition, such as congestive heart failure or an irregular heartbeat. Avoiding medications that constrict your blood vessels, such as migraine drugs, hormone medications and some heart drugs.

The thickened bowel wall is sometimes associated with the target sign, alternating layers of high and low attenuation within the thickened bowel wall, which results from submucosal edema or hemorrhage.

Can severe constipation cause ischemic colitis?

Constipation has also been identified as a risk factor for the development of ischemic colitis. This is believed to be due to increased intraluminal pressures causing compression of the blood vessels and resultant decreased mucosal vessel flow.
