Superficial leg veins, also known as spider veins, telangiectasias, or starburst blemishes are small, dilated surface veins that can be pink, red, or purple and appear as lines or clusters mostly on lower extremities.
If you are considering a sclerotherapy as a treatment to improve the appearance of unwanted spider veins, learn how this minimally invasive techniques can improve their appearance.
Dysfunction of the valves within veins contributes to appearance of spider veins, and several factors may play a prominent role in their development and progression. These factors include heredity, pregnancy, hormone replacement therapy, oral contraceptives, obesity, and trauma. Although exercise, weight loss, and support hose may limit the number of new vessels, it will not fully prevent their development.
Performed on an outpatient basis, sclerotherapy involves the injection of a sclerosing solution, (such as hypertonic saline, glycerin or Sotradecol, Asclera) into the abnormal dilated vessels. This causes the lining of the vessels to swell and the lumen to close. In many cases, the veins can be completely eliminated.
Most people experience mild discomfort for about 15 to 30 seconds, similar to a mosquito bite. The injected veins completely disappear for a few minutes as blood is pushed out by the solution, but they reappear when the blood flow returns. Since many vessels are interconnected, one injection may eradicate several dozen vessels at once by washing over the cells lining the inner wall of the vessel, causing them to shrink. The veins will slowly disappear following the injection.
Veins will fade over six to eight weeks after treatment. Smaller vessels may disappear completely and large vessels may decrease in size and/or completely disappear.
Serious side effects from this procedure are extremely rare; however, some temporary side effects may occur.
Pressure gauze bandages may be placed over the treated vein and remain overnight after treatment. You should avoid contact sports, aerobics, and use of leg weights during this treatment. A 30-minute, moderately paced walk may be substituted for your regular workout. Thereafter, compression support hose must be worn continuously (except to shower) for five days after treatment. Medium-weight compression support hose are recommended for daytime wear during the one to two weeks following treatment; either Jobst sheer support pantyhose or Sigvaris Delilah pantyhose. Both are nonprescription, fitted by height and weight and available in several colors.
