Before the procedure:
You may be required to complete an ultrasound imaging exam of the affected area. The exam is an integral part in assessing the diseased vein and planning the procedure and is virtually painless.
During the procedure:
Sclerotherapy is an outpatient procedure which requires no anesthesia. A fine needle is used to gently insert the specialized solution into the diseased vein. The solution, usually in liquid form, works by irritating the lining of the vein, causing it to swell shut and block the flow of blood. On occasion a foam version of the solution may be used, particularly when a larger vein is involved. Foam tends to cover more surface area than liquid. Some solutions contain a local anesthetic called lidocaine to aid with mild discomfort. The number of injections depends on the amount and size of veins being treated.
After the procedure:
You will be asked to wear compression socks or stockings to maintain compression on the treated veins. Your post-treatment care will be tailored to your needs. Unless otherwise stated you can return to normal activity immediately after the procedure. Limited sun exposure is recommended shortly after treatment, the inflammation caused by the injections combined with sun exposure can lead to dark spots on your skin. The treated vein(s) will become scar tissue and eventually disappear.
