Endovenous Ablation Definition

Taken literally, endovenous ablation is the removal of a vein from within. ‘Endo’ means internal or inside, ‘venous’ refers to a vein, and ablation is to ‘remove’.

In the instance of veins, it is no longer necessary to physically remove a vein from the leg (vein stripping) to improve symptoms or the condition of chronic venous insufficiency. Technology exists in which the vein can be treated or ablated utilizing different forms of ablation.


Endovenous Vein Ablation Techniques

The three endovenous techniques which are currently used are; chemical closure (sclerotherapy), thermal closure (endovenous radiofrequency ablation or endovenous laser vein ablation), and the newest method is adhesive closure VenaSeal, a non tumescent non thermal vein closure. All three techniques close the veins off by accessing them with needle puncture and damaging the vein from the inside. By inflicting damage to the inside of the vein with either sclerosant, heat energy or adhesive, the veins are permanently closed and over time the body breaks this tissue down and carries it away.

The most common technique associated with the term endovenous ablation is the thermal technique. While inside the vein with either radiofrequency or laser energy, the vein is closed utilizing the thermal or heat energy delivered by the device. This technique requires an initial venous consultation and duplex ultrasound. It is also the technique recognized by most insurance companies and is indicated for treatment of symptomatic venous insufficiency in patients who have failed conservative therapy such as compression stocking use.
