CLaCS - innovative treatment of varicose veins

The name CLaCS stands for Cryolaser and Cryosclerotherapy and means a combination of laser and sclerotherapy treatments using vascular imaging in “augmented reality” using the Vein Viewer device. The method was developed and put into practice by renowned vein specialist Dr. Kasuo Miyake (Sao Paulo, Brazil). The entire treatment is performed while the skin is constantly cooled by cold air at temperatures as low as -30 degrees C. The CLaCS method is based on a combination of two methods: laser capillary closure and sclerotherapy. The procedure is performed by vascular surgeons, i.e. doctors specialising in the diagnosis and treatment of venous diseases.

Thin veins directly under the skin on the legs plague people as often as varicose veins, also called spider veins.  They are usually not visible, but over time they usually rise to the surface, swell and become slightly inflamed. These veins are purple, dark blue or red in colour.  I tis better to seek solution for their removal rather than underestimating them. Varicose veins are the first stage of chronic venous disease. Do not allow more serious symptoms of varicose veins to develop.

In Blumental Clinic, we use the state-of-the-art CLaCS method, combining the QUANTA light C EVO cryolaser with the Zimmer Cryo 6 high cooling rate cooling device. The procedure is performed with the help of the state-of-the-art VeinViewer Vision2 infrared camera.

Don't hesitate to find out what treatment or procedure is best for you

In the first stage of the procedure, the doctor “X-rays” a specific area on the leg using the Vein Viewer device, which locates all the blood vessels present in that area at a depth of 2-8 mm. Thanks to this, the specialist is able to plan exactly the area to be worked on, i.e. which veins he wants to close and in what way. The treatment starts by closing the shallowest areas with the laser. The entire procedure is performed using a cold air cooling device without anaesthesia. The laser can remove spider veins / reticular veins up to 4 mm in diameter. The procedure usually takes 20 to 30 minutes, depending on the extent and number of pulses. Then the next phase of treatment begins, which involves closing the blood vessels located slightly deeper under the skin using sclerotherapy, constantly cooling the skin. Cooling the skin throughout the treatment is extremely important, it reduces pain during the procedure, creating a larger treatment area and protecting the skin from burning. No creams can be used after the procedure. Sometimes the doctor puts a special dressing on the injection site – a gauze pad rolled into a ball, sealed with a wide patch. The interval between sessions should be 4-6 weeks. Usually there is no need to wear bandages or compression stockings.

This happens after the treatment

  • Can walk immediately after surgery
  • With the CLaCS method, airplane flight is not contraindicated
  • There is no need to wear compression stockings after the treatments, which are compulsory in classical sclerotherapy.

The biggest advantage of this method is the fact that it also hits the deeper vein under the skin surface, which “nourishes” the spider veins and thus eliminates the causes of the formation of “spider veins” and not just the spider veins themselves, which prevents recurrence – so the spider veins do not form again.

Reticular veins are the first signs of vein disease, and it is better to address them before they darken, swell and bulge to the surface.
The procedure is performed without anaesthesia. Throughout the procedure, the treatment site is cooled by a special cold air device, which numbs and protects the site.
