Radiofrequency Ablation Endovenous Therapy in Knoxville, TN
Endovenous Radiofrequency Ablation (RFA) is a minimally invasive procedure for varicose veins in which a vein specialist inserts a tiny catheter through a small incision below the knee. Guided by ultrasound imaging, the diseased vein is treated with a short burst of radiofrequency energy, causing the vessel to shrink around the catheter. The physician withdraws the catheter, treating each segment until the entire length of the diseased vein has been sealed. After the vein is sealed shut, blood then re-routes to healthy veins.
This procedure is performed in-office and is covered by most health insurance plans.

Endovenous Laser Therapy in Knoxville, TN

Endovenous Laser Therapy (EVLT) is a non-invasive treatment for larger veins. Laser energy delivered through a small puncture in the leg is used to treat the diseased vein. Guided by ultrasound, a tiny optic fiber laser is inserted through a needle into the varicose vein. The laser heats and closes the vein, allowing blood to be naturally re-routed to other healthy veins. EVLT is often performed in conjunction with sclerotherapy to treat the smaller veins.Â
There is no surgery or hospitalization, and only a local anesthetic is applied. The procedure is performed in the office in about an hour. Normally, patients resume regular activity within a day. Most insurance plans and Medicare cover Endovenous Laser Therapy.
