New treatment options for leg varicose veins

Guest, ,

Varicose veins can be a troublesome problem for both men and women. We invited the vascular surgical specialist Dr. Rodrigo Bono Fukushima to discuss new treatments,

There are several treatment options for varicose veins in the legs. The choice of the best treatment will depend on various factors, such as the location of the varicosities, the patient’s age, the evolution of the disease, and the complexity of the patient’s disease.

The best treatment is very individual. What is best for one person will be different for another. Further, it is not uncommon to require more than one treatment. Therefore, before any treatment, it is important to have a detailed evaluation by a vascular specialist.

Techniques have evolved in recent years, enabling patients to reduce recovery time with better long-term results. Here are some options.

Laser for varicose veins

The advent of the laser in vascular surgery was a milestone. It benefits patients who require treatment for micro and larger veins, and for patients who have varicose veins at different stages.

CLaCS – Cryo-Laser and Cryo-Sclerotherapy

Transdermal laser is another important advance in the techniques of sclerotherapy for the treatment of micro varicose veins and telangiectasias (“spider veins”). The CLaCS technique (Cryo-Laser and Cryo-Sclerotherapy) joins the 1064nm Nd-Yag laser with liquid sclerotherapy using hypertonic glucose.

The technique consists of the application of a transdermal laser with injection of a 75% glucose in the same session. Throughout the procedure, the skin is cooled to -32oC. The procedure is performed using an augmented reality device, which enlarges the visualization of the vessels and allows for more precise treatment.

The laser emits a collimated light, at a specific wavelength that targets the varicosities, yet with minimal interaction with the skin. Thus it is possible to treat the veins without injury to the skin.

A 75% glucose solution is injected into the same vessels treated by the laser. The goal is to add a second injury, which augments the result. The association of these two techniques potentiates their effect, allowing for treatment of larger caliber veins, with faster and more lasting results.

Advantages of CLaCS

— Safety

— Fewer number of sessions

— More rapid treatment

— In some cases, it replaces conventional surgery

— Can walk right after surgery

— No limitations for physical activities

— Greater precision using augmented reality

Surgical treatment with Intravenous Laser

Another option is surgical treatment, and the techniques have evolved over the years. Currently, the procedure is performed using minimally invasive techniques, making it safer with faster recovery.

The intravenous laser consists of an optical fiber that emits heat at its end. It is introduced into the saphenous vein at the ankle by an ultrasound guided puncture. The fiber is guided to the groin area without the need for cuts. Then a thermocoagulation of the entire saphenous segment is performed, causing its closure and later reabsorption.

Advantages of Intravenous Laser surgery

— Quick return to activities (usually 2 to 3 days post-procedure)

— Minor operative trauma

— Less pain and less bruising

— Better post-procedure course

— Excellent effectiveness

— Lower incidence of complications

— Lower severity of complications

If you have varicose veins, know that these are only some of the treatment possibilities. Find a vascular specialist and learn which treatment is best for you.
