Types of Endovenous Ablation Procedures for Varicose Veins

Blood vessels flowing through a vein

Endovenous ablation therapy is the most modern type of treatment for diseases affecting peripheral veins. It is a minimally invasive procedure typically used for varicose vein treatment. It involves inserting a needle directly into damaged veins to ablate clots.

One reason varicose veins patients delay seeking help is misinformation on the treatment options. Leg swelling and pain are the primary symptoms that drive most St. George residents to seek help. This is according to Heart of Dixie Vein Center. Fortunately, endovenous ablation has changed the face of varicose vein treatment for even those whose problem is late diagnoses. That said, below are some kinds of endovenous ablation procedures available to you.

Endovenous Laser Treatment

This is a minimally invasive, non-surgical procedure. It is typically a substitute to great saphenous vein stripping. After applying local anesthesia, the specialist inserts a laser fiber into the diseased vein. Laser pulses are then passed onto the vein, causing it to collapse. Endovenous laser treatment is 98% effective, and the procedure takes around 30 minutes.

Endovenous Radiofrequency Ablation

This is also a minimally invasive procedure used for great saphenous vein treatment. The phlebologist applies local anesthesia to the knee. They then insert a radiofrequency catheter with 350–500 kHz of current into the diseased vein. This catheter carries radiofrequency waves to the damaged vein wall and causes it to collapse and seal shut. The process is less painful than laser treatment and has a 96% success rate.


Experts also refer to this as ultrasound-guided sclerotherapy. Specialists inject a foam or liquid sclerosant directly into damaged veins with the guidance of an ultrasound machine. It is a highly effective and safe treatment option for damaged veins with a diameter of less than 3mm. Specialists commonly use this in the treatment of reticular veins and spider veins.

There are many advantages of endovenous ablation over other procedures to treat varicose veins. The treatment has a higher success rate, faster recovery and leaves no scars. There is also no need for hospitalization after the procedure, and there is a lower risk of blood clot formation.
