VNUS Closure Procedure in Visalia, CA
VNUS ablation uses thermal energy to effectively close down varicose veins. When applied to the inside of a varicose vein, thermal energy causes the walls of the vein to collapse. The elimination of a major vessel causes blood to resume flow through nearby healthy veins, which helps to restore healthy circulation in the leg.
The VNUS Closure procedure is performed using a catheter-based device that is outfitted with a heating element and connected to a radiofrequency (RF) generator. Prior to activating the heating element, the saphenous compartment, which surrounds the vein, is filled with a liquid referred to as tumescent anesthesia. Tumescent anesthesia acts as a heat sink to protect surrounding tissue from excessive temperatures during treatment, and also numbs the area to minimize any pain or discomfort during the procedure.

The catheter is inserted into the leg through a single puncture
Tumescent anesthesia is injected into the saphenous compartment
Radiofrequency or laser energy is applied to the heating element
Vein wall collapses from heat-induced collagen denaturation
