Sclerotherapy is an invasive technique where a chemical solution is injected into the veins and capillaries of the affected blood vessels. The solution injected is a sclerosing agent that irritates the walls of the veins, which then causes the veins to collapse. Once collapsed, the injected veins scar and are resorbed by the body, leaving behind little to no evidence of the varicose vein. Blood circulation that had previously flowed through the vein is rerouted to healthier veins.
One of the cons of sclerotherapy is the discomfort of the procedure that has been likened to the sensation of multiple pinpricks or mosquito bites. To alleviate this discomfort, Dr. Pittman uses a type of sclerotherapy called “cryo-sclerotherapy” where the skin is cooled and numbed at the injection site during the sclerotherapy treatment.
“With cryosclerotherapy, the skin is chilled with cold blasts of frigid air to numb the skin which is applied to the injection sites before inserting the sclerosing agent into the affected veins.
“It’s painless—you barely feel anything; most of the time you do not feel anything” states, Dr. Pittman.
