In nonthermal ablation techniques, chemicals are used to cause a damaged vein to collapse and disappear.
Your doctor may recommend a procedure in which a chemical foam, called Varithena®, is injected into the vein.
For this procedure, the vein specialist administers a local anesthetic and then inserts a catheter into the leg. Using ultrasound images to guide the catheter, the doctor injects a small amount of the foam through the catheter into the vein.
This causes the affected leg vein to collapse. Blood is then redirected to healthy veins.
This procedure takes less than an hour. You can go home the same day and resume your usual activities. Your doctor may recommend avoiding heavy exercise for up to one week after the procedure.
Mechanico-chemical ablation, also called ClariVein®, typically requires fewer injections of local anesthesia than thermal procedures.
In this procedure, the vein specialist uses ultrasound to guide a catheter into the affected vein. Next, a liquid chemical is delivered to the vein while a small, rotating metal wire helps to destroy the vein. Blood is rerouted to healthy veins.
This procedure takes less time than other minimally invasive procedures, and you can go home the same day.
A medical adhesive may be used to close a damaged vein, sealing it shut, in a procedure that is also called VenaSeal®.
Your NYU Langone vein specialist inserts a catheter and then uses ultrasound guidance to advance the catheter. The doctor then delivers several precisely measured injections of the medical adhesive into the vein and presses on the vein using his or her hand. This helps the vein walls adhere, closing them off. Blood is rerouted to healthy veins nearby.
The procedure takes less than an hour, and you can go home the same day.
