Sclerotherapy is typically used to treat spider veins
or small varicose veins.* During this procedure,
a solution is injected into the vein using tiny needles.
This solution (sclerosant) causes damage to the inside of the vein,
which causes the vein to close. In time, the vein is absorbed into the body.
The procedure usually takes place in our comfortable Vein Center facility using a local anesthetic. Using a series of tiny injections, a saline solution or other solution is injected into the vein. Or, in some cases, a tiny catheter may be inserted into the vein to allow the use of a foam sclerosant – if a catheter and foam are used, they will be guided by the use of duplex ultrasound. Some patients experience a feeling of minor burning and discomfort during the procedure. Repeat injections may be necessary to achieve the desired results. Depending on the size and number of veins being treated, the procedure is usually completed in 5 to 30 minutes. Before leaving the office, patients put on medical-grade compression stockings or elastic bandages as directed by their physician. Most patients are able to walk immediately after the procedure, but should refrain from strenuous exercise for approximately one week after treatment.
