Your physician may choose either laser treatment (EVLT) or radiofrequency energy (VNUS closure) to perform the ablation procedure. A vein ablation is a minimally invasive procedure for superficial venous reflux, in which a thin catheter is inserted into the vein through a small opening and heat is used to collapse and seal the vein shut.
Since valves cannot be repaired, the only alternative is to re-route blood flow through healthy veins. Traditionally, this has been done by surgically removing (stripping or ligating) the troublesome vein. These procedures provide a less invasive alternative to stripping or ligation by simply closing off the problem vein instead. Once the diseased vein is closed, other healthy veins take over the transport of blood from the legs back to the heart.
With the EVLT or VNUS closure procedures there is no need for formal surgery. Instead, the vein remains in place and is closed using a special catheter inserted through a small puncture. This virtually eliminates the bruising and pain often associated with surgery. In addition, surgery for the vein is usually performed in an operating room under general anesthesia, while ablation treatments are performed in an outpatient setting using local anesthesia.
Vein ablation using the laser or the radiofrequency technology both take approximately 30 minutes to an hour, though patients normally spend 60-90 minutes at the medical facility due to normal pre- and post-treatment protocols.
