The leg being treated will be cleaned, sterilized, and covered with a surgical drape. Your physician will numb the area where the catheter will enter into the abnormal vein and use the ultrasound transducer or wand to study the vein and track its path. A very small skin incision is made at the site.
Using ultrasound guidance, a catheter or vascular access sheath is inserted through the skin and positioned within the abnormal vein. This catheter will then close the bad vein and then the catheter itself is removed from the body. No foreign objects are left inside the body.
A small bandage is used to cover the small skin opening and the leg is wrapped with a compression wrap. No stitches are needed.
