What is VenaSealTM?

The VenaSealTM procedure uses nonthermal treatment to close refluxing or diseased veins.  The system delivers a small amount of medical adhesive to “glue” the vein closed.  The adhesive permanently seals the vein closed and blood will reroute to normal healthy veins.  The procedure takes around 45 minutes to perform.  It is done under local anesthesia (lidocaine) which is injected at the IV insertion site.  No additional anesthesia is needed for the procedure. 

Why is VenaSealTM used?

The VenaSealTM procedure is used to treat patients with varicose veins and/or symptomatic venous insufficiency.

Some symptoms of venous reflux include:

Superficial varicose veins or spider veins

Cramping or aching of the legs


Night cramps or restless leg

Heaviness or fatigue of the legs


Skin discoloration

Open ulcers or nonhealing wounds

What to expect during and after the procedure

A small injection of local anesthesia will be injected at the IV site.  No additional anesthesia is required.  Patients may experience a “pulling” or “tugging” sensation during the procedure but should experience minimal to no additional discomfort.  If desired a prescription of Xanax, a mild oral sedative, can be given to you prior to the date of your procedure.  It will be your responsibility to fill the prescription at the pharmacy and bring the medication with you to your procedure.  We recommend that the medication be taken 20-30 minutes prior to your procedure.  (Xanax medication information sheet link).  If you decide to take the medication for your procedure it is our policy that you have a trusted adult accompany you to the procedure and remain with you for 4-6 hours after the procedure. 

Usually one diseased vein is treated at a time.  A compression wrap may be placed after the procedure if needed.  No post treatment compression stockings are required but may help with some of the inflammation and swelling.  It is recommended to take Benadryl 25mg at bedtime, Pepcid 20mg daily, and ibuprofen 800mg three times daily for 3 days following the procedure to prevent phlebitis (inflammation of the vein in response to the treatment).   Further information will be given to you by your healthcare provider and in your preoperative instructions regarding this recommendation. You can return to normal activity after the procedure.  We advise that you walk at least 30 minutes per day for 2-3 days following the procedure.  This will help to prevent stasis of blood in the veins that can lead to blood clots.   Post procedure ultrasound will be performed within 1-2 weeks to ensure good closure of treated vein and no deep vein complications.
