Sclerotherapy Vein Treatment


This non-invasive, outpatient procedure uses a mild chemical solution, called a sclerosant, to treat spider veins and varicose veins. In some cases, ultrasound may be used to guide the injection. 

Injecting the Sclerosant

After the area is cleansed and sterilized, the physician inserts a needle into the target vein and injects the sclerosant. In cases of spider veins, the physician may treat the feeder vein, which supplies blood to the visible branches.

Vein Collapse

The sclerosant irritates the wall of the blood vessel, causing it to restrict and collapse. The flow of blood will be redirected to other healthy veins in the area. The physician may make multiple injections along the target vein to complete the treatment. Over time, the body will absorb the collapsed vein.

End of Procedure

The leg is bandaged tightly for several hours to help keep the treated vein closed. Patients will be able to return to normal activities immediately after the procedure. Compression hose may need to be worn for several days after the procedure.
