Modern Methods of Intravascular Ablation

A Review of Endovascular Ablation Methods for the Treatment of Varicose Veins of the Lower Extremities

Varicose veins of the lower extremities are a common health problem that affects many people around the world. Modern medicine offers a variety of treatment methods for this condition, including minimally invasive endovascular ablation techniques. In this article, we will examine the most important ablation methods used to treat varicose veins.

What are varicose veins?

Varicose veins are enlarged, twisted veins that most commonly appear on the legs. They develop as a result of venous valve insufficiency, which leads to blood pooling and increased pressure in the veins. Symptoms of varicose veins may include pain, swelling, a feeling of heaviness in the legs, and skin changes. In more advanced stages of the disease, ulcers and tissue necrosis may also occur.

Intravascular Ablation Methods

1. Laser Ablation (EVLA) Laser ablation involves inserting a fiber optic cable into the affected vein and then exposing it to laser light. The high temperature causes the vein to close, leading to its gradual disappearance. This procedure is effective and minimally invasive, and patients quickly return to their normal activities.
2. Radiofrequency Ablation (RFITT) This method uses radiofrequency waves to heat and seal off incompetent veins. Similar to laser ablation, the procedure is minimally invasive and performed under local anesthesia. RFITT is highly effective and involves a short recovery time. Additionally, it allows for a lower treatment temperature and prevents tissue overheating thanks to biofeedback.
3. Sclerotherapy Sclerotherapy involves injecting a special sclerosing agent into a vein, which causes it to close. This method is particularly effective in treating smaller varicose veins and telangiectasias. Sclerotherapy can be used as a complement to thermal ablation methods and can be assisted by vascular illuminators.

Advantages of endovascular ablation methods

Endovascular ablation techniques offer many advantages over traditional surgical methods. They are less invasive, which means a lower risk of complications, a shorter recovery time, and better cosmetic results. In addition, most procedures can be performed on an outpatient basis, which increases patient comfort.

Summary

Endovascular ablation is a modern and effective method for treating varicose veins in the lower extremities. Thanks to a variety of techniques, such as laser ablation, radiofrequency ablation, sclerotherapy, and steam ablation, treatment can be tailored to the patient’s individual needs. It is advisable to consult a specialist to choose the most appropriate treatment method.
