What is a surgical bypass for visceral ischemic syndrome?

A surgical bypass reroutes blood flow around a blocked blood vessel by creating a new pathway for blood flow using a graft.

Why is this procedure performed? Why do I need this procedure?

The goal of treatment is to re-direct the blood flow in the artery to bypass a blockage. You may need this procedure if your arteries become too narrowed or blocked from plaque inside the artery walls. If arteries are blocked, blood cannot get through to nourish the tissues of the bowel or gastrointestinal system (intestines).

Acute mesenteric ischemia is a life-threatening condition. In contrast, chronic mesenteric ischemia is characteristically associated with abdominal pain after meals. The onset of pain is usually gradual and progressive. Eventually, this situation results in substantial weight loss and a marked alteration in dietary intake.

Each patient is evaluated, and treatment will be individualized for the patient's circumstances.

Where is the procedure performed and who performs this procedure?

This procedure is performed in the hospital surgical suite by a vascular surgeon.

What are the risks and potential complications of the procedure?

Your doctor will discuss the specific risks and potential benefits of the recommended procedure with you.

Bypass surgery usually has no complications, but there may be a risk of injury to the blood vessel. Another possible complication is the development of a hernia at the site of incision. In addition, the return of normal bowel function may be slow, and patients may not be able to eat for several days following the surgery. Your vascular surgeon will discuss the important risks and benefits with you.

Special precautions are taken to decrease these risks, and there may be other possible risks. When you meet with your doctor, please ask questions to make sure you understand the risks of the procedure and why the procedure is recommended.
