Endovenous laser treatment

During endovenous laser treatment, a laser fiber produces endoluminal heat that destroys the vascular endothelium.

A Seldinger technique with endovenous laser treatment,  is used to advance a long catheter along the entire length of the truncal varicosity (usually the GSV) to be ablated.

A bare laser fiber is passed through the catheter until the end protrudes from the tip of the catheter by approximately 2 cm, and the laser fiber tip is positioned at the SFJ just distal to the subterminal valve.

The position is confirmed by ultrasound and by use of the laser guide light.

During laser vein treatment, under ultrasound guidance, tumescent solution with a local anesthetic is injected around the entire length of the vessel, separating it from its fascial sheath. This serves to insulate the heat from damaging adjacent structures, including nerves and skin, as well as pain control, which is one of the major advantages of the endovenous laser treatment.

Firm pressure is applied to collapse the vein around the laser fiber, and the laser is fired generating heat, leading to intraluminal steam bubbles and irreversible endothelial damage and thrombosis.

The fiber and catheter are withdrawn approximately 2 mm, and the laser is fired again. This process is repeated along the entire course of the vessel.

Endovenous laser treatment is one of the best techniques to treat varicose veins.
