Endovascular Cryoplasty


  • Endovascular cryoplasty, also known as cryoplasty (CRY-o-plah-stee), is a type of balloon angioplasty (AN-g-o-plah-stee) procedure. It is used to treat peripheral vascular disease (PVD). Cryoplasty is therapy that uses pressure and cold to open blocked or narrowed arteries. Arteries are blood vessels that carry blood with oxygen from your heart to another part of the body. They can become clogged by plaques that decrease blood flow in the artery. Plaques are fat, cholesterol, or tissues that get stuck in the inner wall of the artery. Cryoplasty is often used to open clogged arteries in the legs. Decreased blood flow may cause severe leg pain and trouble walking that can affect your quality of life.
  • With cryoplasty, a small balloon-tipped catheter is put into a large blood vessel in the groin. The groin is the area where your abdomen (stomach) meets your upper leg. The catheter is passed down into the area of the clogged area of the artery. The artery is opened and cooled using a high pressure balloon filled with nitrous oxide (laughing gas). Cryoplasty may be done after caregivers strip and cut the plaque first. It may also be followed by stenting. Stenting is a procedure that places small tubes in the area where the blockage was removed to keep the artery open. Having cryoplasty may improve the blood flow in your leg to relieve your symptoms and avoid further problems.



  • Keep a current list of your medicines: Include the amounts, and when, how, and why you take them. Take the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency. Throw away old medicine lists. Use vitamins, herbs, or food supplements only as directed.
  • Take your medicine as directed: Call your primary healthcare provider if you think your medicine is not working as expected. Tell him about any medicine allergies, and if you want to quit taking or change your medicine.

Follow-up visit information:

Keep all appointments. You may need to return for tests to check your blood flow. You may also need to have your wound checked. Write down any questions you may have. This way you will remember to ask these questions during your next visit.


Exercise makes the heart stronger, lowers blood pressure, and helps keep you healthy. Begin to exercise slowly and do more as you get stronger. Talk with your primary healthcare provider before you start an exercise program.
