Angiodysplasia of the colon

Definition

Alternative Names

Vascular ectasia of the colon; Colonic arteriovenous malformation

Causes

Symptoms

Exams and Tests

Tests that may be done to diagnose this condition include:

  • Angiography (only useful if there is active bleeding into the colon)
  • Complete blood count (CBC) to check for anemia
  • Colonoscopy
  • Stool test for occult (hidden) blood (a positive test result suggests bleeding from the colon)

Treatment

It is important to determine what is causing the bleeding in the colon and how fast blood is being lost. You may need to be admitted to a hospital. Fluids may be given through a vein, and blood products may be required.

Other treatment may be needed once the source of bleeding is found. Most patients stop bleeding on their own without any treatment.

If treatment is needed, it may involve:

  • Angiography to help block the blood vessel that is bleeding or to deliver medicine to help cause the blood vessels to tighten to stop the bleeding
  • Burning (cauterizing) the site of the bleed with heat or a laser using a colonoscope

Outlook (Prognosis)

Patients who have bleeding related to this condition despite having had colonoscopy, angiography, or surgery are likely to have more bleeding in the future.

The outlook remains good if the bleeding is controlled.

Possible Complications

  • Anemia
  • Death from excessive blood loss
  • Side effects from treatment
  • Severe loss of blood from the GI tract

When to Contact a Medical Professional

Call your health provider if rectal bleeding occurs.

Prevention

There is no known prevention.
