What is mesenteric artery angioplasty and stenting?

Patients with mesenteric ischemia typically have blockages in many of the vessels in their superior mesenteric artery and the celiac axis.
To clear these blockages, an interventional radiologist makes a small incision in the arm to insert a catheter via the brachial artery. Using image guidance, the catheter is guided down the chest into the abdominal aorta. A wire is passed through each blockage and then a covered stent mounted on a balloon to open the vessels may be placed.
The access can also be via the femoral artery in the groin, but that is not always the easiest route due to the sharp angles required to navigate the catheter.

Why would you need mesenteric artery angioplasty and stenting?

Mesenteric artery angioplasty and stenting may be used to bypass the fatty deposits that build up in the arteries that feed the intestines. This decreased blood flow to the intestines is chronic mesentery ischemia. Treatment of symptomatic chronic mesentery ischemia is necessary to prevent acute mesenteric ischemia, which may cause bowel infarction and death. Asymptomatic disease does not constitute an indication for treatment, although prophylactic treatment may be necessary in cases of planned abdominal surgery because of probable loss of collateral blood vessels during surgery.

Risks Involved

Our ability to use imaging guidance and cutting-edge technology minimizes patient risk. Prior to your procedure, your physician will discuss any potential risks with you.

Conditions to let us know about

Let your doctor know if you currently are pregnant or breast feeding, feeling ill, have a fever, or are taking any blood thinners.

Insurance coverage

Mesenteric artery angioplasty and stenting is covered by most private insurance providers as well as Medicare. We will seek authorization from your insurance company prior to your procedure.

Preparing for your procedure

If you are on blood thinners your doctor will instruct you if you need to stop these medications prior to the procedure. If your procedure requires sedation, then you will need a responsible adult to give you a ride home.

Recovering from your procedure

You may possibly receive mild to moderate sedation during your procedure. You will stay in the recovery area until you are ready for discharge. You will be given written post procedure discharge instructions that will advise you about return to normal physical activity. If you have any questions after your procedure, please call the RIA Interventional Suite at 720-493-3406.
