Endovenous thermal ablation

Endovenous thermal ablation


During endovenous thermal ablation, the surgeon inserts a very thin tube, or catheter, into the enlarged vein. Heat is applied through the tip of the catheter. When the catheter is withdrawn, the heat causes the vein to collapse and the blood to reroute through healthier veins. Catheter-assisted methods can use radiofrequency waves or lasers to close the main vein.
