Endovenous Laser Ablation (EVLA): State-of-the-art therapy for Varicose Veins

Endovenous Laser Ablation (EVLA): State-of-the-art therapy for Varicose Veins

In a human body, the Veins are considered as the ‘highways’. They serve to carry blood pumped by the heart along a network of ‘roads’ consisting of arteries and veins and carry oxygen to all parts of the body. Natural body movement helps pump blood back to the heart, which pumps it out again in a continuous cycle.

Veins have valves that open and close to make sure blood is always flowing in the correct direction. Varicose veins are dysfunctional veins and can cause leakages which causes the  legs to be clogged with toxins and deoxygenated blood. In a varicose vein, blood flows backward and stays in the vein. This causes the vein to expand, stretch, and become twisted, which prevents it from circulating blood effectively. 

A procedure called Endovenous laser ablation therapy (EVLT) can treat Varicose veins without surgery. It is a minimally invasive procedure that makes use of catheters, lasers, and ultrasound to treat varicose veins. In this procedure the abnormal veins are heated by laser and destroyed.

Nervous about what to expect during EVLT? The procedure is detailed here for your better awareness if this is considered as an option for treatment of your varicose veins.  

EVLT Procedure

A simple ultrasound scan can detect the veins that need treatment and appropriate markings are made. Small amount of local anesthetic is injected into the skin over the vein and a needle is inserted into it. A wire is then passed through the needle and up the vein. Ultrasound is used to see inside the patient and the doctor guides a catheter through the vein. 

Laser fiber is then passed through the catheter, with its tip at the highest point to be heated. Local anesthesia is then injected through needle pricks. For a few minutes laser is fired up and dragged down. The damaged veins thus collapse and get sealed. The dead tissues will gradually get absorbed by the body. 

The blood thus gets diverted to numerous stronger, healthier veins. Laser and catheter are removed and the needle punctures are neatly dressed. Compression stockings are recommended for a few weeks during the recovery process to aid circulation. This helps to minimize the amount of bruising or swelling that can occur after the procedure. An ultrasound may be performed during the follow-up to ensure no clots have formed in the treated veins.

Complete procedure takes about 30 minutes for each leg. Doctors generally prescribe anti-inflammatory drugs which can relieve mild pain that can be felt after the procedure.

Getting rid of damaged veins improves the circulation as the healthy veins now do a much better job, without being disturbed by the leaking varicose veins. Patients experience improved general well-being as legs start feeling lighter and the associated heaviness, aching and cramping are normally reduced.
