Sclerotherapy is one method for the treatment of spider veins, varicose veins (which are also often treated with surgery, radiofrequency, and laser ablation), and venous malformations. In ultrasound -guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection.
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 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]
The phlebectomy hook is inserted through an incision and the varicose veins is hooked, extracted, and subsequently fixed with a clamp (e.g. Mosquito clamp). Next the vein is pulled out by turning or "wenching" the exteriorized part of the vein and moving the clamps as the vein is pulled out further.
Ultrasound is applied using a transducer or applicator that is in direct contact with the patient's skin. Gel is used on all surfaces of the head to reduce friction and assist transmission of the ultrasonic waves. Therapeutic ultrasound in physical therapy is alternating compression and rarefaction of sound waves with a frequency of 0.7 to 3.3 ...
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
