A typical sclerotherapy session is relatively quick, lasting only about 15 to 45 minutes. You will be asked to lie down on the examination table and the skin over your spider veins will be cleaned with an antiseptic solution. Using one hand to stretch the skin taut, your doctor or nurse will begin injecting the sclerosing agent into the affected veins with a tiny needle. Bright, indirect light and magnification help ensure that the process is completed with maximum precision.
Approximately one injection is administered for every inch of spider vein – anywhere from five to 40 injections per treatment session. A cotton ball and compression tape is applied to each area of the leg as it is finished.. In addition, tight-fitting support hose may be prescribed to guard against blood clots and to promote healing. The support hose can be removed after 72 hours.
You should be aware that your treated veins will look worse before they begin to look better. Two or more sessions are usually required to achieve optimal results.
