The ClosureFast Procedure

Using Radiofrequency ablation to treat your vein disease

The ClosureFast Procedure is also known as radiofrequency ablation. This procedure has been used to treat over 2 million patients in over 100 countries! It is a well established and time proven procedure. It has a long standing proven outcome and rapid recovery. Also, it is covered by most insurance plans!

The ClosureFast is an in-office procedure that typically takes about 30 minutes. The procedure requires only local anesthesia. Patients go home after the procedure is completed and can often return to work the same day. It uses radiofrequency energy to close the diseased vein and reroute blood flow to the healthy veins in the leg. 

ClosureFast Procedure

What can I expect from the ClosureFast Procedure?


You will see one of our vein specialists at CVVS for a consultation. An ultrasound will identify which veins require treatment. A Board Certified Vascular Surgeon will determine if you are a candidate for the ClosureFast procedure. Your surgeon will discuss every detail about the procedure and will answer all questions you may have.

On the day of the procedure, you will be asked to wear loose clothing for your arrival to the office. You are able to eat and drink as you wish prior to the procedure.


  • At Coastal Vein and Vascular Specialists, we have a dedicated private room just for vein procedures.
  • After you remove your pants, you will be covered in a sheet and placed on a comfortable stretcher. Our CVVS Certified Medical Assistant will help you get situated. Your leg will be prepped with a sterile solution and placed on top of a sterile drape.
  • A CVVS Board Certified Vascular Surgeon will use an ultrasound to identify the affected vein in your leg that will need the procedure. You will receive a very small injection with local anesthetic to the access area of the vein.
  • Once the area is numb, your doctor will insert the catheter (small tube) into the vein. You may feel slight pressure in the area, but you will experience no pain or significant discomfort.
  • The surgeon will use the ultrasound to guide placing local anesthetic along the entire course of the diseased vein that requires treatment. Next, the radiofrequency catheter will be placed along the vein and activated. This catheter will deliver energy to the vein, causing it to shrink and the vein is closed. The surgeon will use the ultrasound to confirm the vein has been closed.
  • After treatment, the catheter will be removed and a band-aid will be placed at the insertion point. We will ask you to bring a thigh-high compression stocking which will be placed on your leg immediately after the procedure. We ask that this compression stocking be worn all day, every day for 7 days.


  • You will be taken to the recovery area to rest.
  • Your CVVS surgeon will recommend appropriate follow-up care.
  • You can resume your normal daily activities immediately, however we do ask that you refrain from any strenuous activity for 1 week.
