Angiodysplasia of the colon

Alternative names:

intestinal arteriovenous malformations

Treatment:

During arteriography, procedures used to control bleeding may be cautery, laser treatment, or blocking the affected vessel in other ways. If massive bleeding occurs, the affected portion of the colon may need surgical resection (partial excision).

Expectations (prognosis):

The probable outcome is usually good with treatment

Complications:

• severe loss of blood from the gastrointestinal tract
• anemia

Calling your health care provider:

Call your health provider if rectal bleeding or tarry stools occur.
