CLaCS (Cryo-Laser and Cryo-Sclerotherapy) is a treatment for leg vein lesions by combining transdermal laser effect and injection sclerotherapy, all under skin cooling (Cryo - cold air blown onto the skin at -20C). [1] [2] [3] The laser causes a selective photothermolysis damaging the vein wall. The vein's lumen gets smaller.
Sclerotherapy has been used in the treatment of spider veins and occasionally varicose veins for over 150 years. Like varicose vein surgery, sclerotherapy techniques have evolved during that time. Modern techniques including ultrasonographic guidance and foam sclerotherapy are the latest developments in this evolution.
Local anaesthetic endovenous surgery using the thermoablation (endovenous laser ablation or radiofrequency), perforator closure (TRLOP) and foam sclerotherapy showed an 85% success rate of healing, with no recurrence of healed ulcers at an average of 3.1 years, and a clinical improvement in 98% in a selected group of venous leg ulcers. [48]
A study of 516 treated veins over 69 months by Elmore and Lackey reported a success rate of 98.1%. [ 6 ] Endovenous thermal ablation (EVTA) by radiofrequency or laser is a safe and effective treatment of refluxing great saphenous veins [ 7 ] (GSVs) and has replaced traditional high ligation and stripping in official recommendations of various ...
Sclerotherapy is often used for telangiectasias (spider veins) and varicose veins that persist or recur after vein stripping. [43] [44] Sclerotherapy can also be performed using foamed sclerosants under ultrasound guidance to treat larger varicose veins, including the great saphenous and small saphenous veins. [45] [46]
Such treatment may allow normal blood flow to resume. It is a non-surgical medical procedure and is not nearly as invasive as debulking. Ultrasound guided foam sclerotherapy is the state of the art new treatment which could potentially close many large vascular malformations. [16] [17] Compression therapies are finding more use as of the last ...
Varicose veins and reticular veins are often treated before treating telangiectasia, although treatment of these larger veins in advance of sclerotherapy for telangiectasia may not guarantee better results. [18] [19] [20] Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open
Sclerotherapy involves the injection of a sclerosing agent, such as phenol, into the hemorrhoid. This causes the vein walls to collapse and the hemorrhoids to shrivel up. The success rate four years after treatment is about 70%. [1]
