- During the sclerotherapy procedure, a health-care professional injects chemicals into smaller veins, which damage the inner lining and produce a clot. As the clot is reabsorbed, the vessel is permanently obliterated.
- The choice of the chemical sclerosing agent and its physical form depend on the size of the vessel to be treated.
- Treatment of the correct vessels can improve the symptoms of venous insufficiency.
- Small superficial vessels are often destroyed for cosmetic reasons.
What is sclerotherapy?
Sclerotherapy is a medical procedure whereby a chemical, the sclerosant, is injected into a vein to entirely obliterate it. The sclerosant damages the innermost lining of the vessel, resulting in a clot that blocks the blood circulation in the vein beyond. Veins carry unoxygenated blood from the peripheral tissues back to the heart. Since the blood pressure in the veins is low, the blood is pumped by forward by contractions of the heart. To prevent back-flow, most veins have valves that only allow blood only to flow in the direction of the heart. When these valves become incompetent, veins become enlarged and bulging (varicose). Smaller veins that feed these varicose veins can also become enlarged and appear as red or blue spider veins in the skin. Varicose veins can lead to a chronic swelling condition of the leg called venous insufficiency. Venous insufficiency predisposes a person to blood clots and skin ulceration. Even more frequently, damaged veins are manifested as unsightly spider veins. The destruction of these types of veins can be desirable both medically and cosmetically.

Is sclerotherapy safe?
All medical procedures have risks that should be considered carefully prior to embarking on a particular treatment. Since sclerotherapy is frequently used to treat cosmetic problems, untoward and dangerous side effects are fully explained to the patient.
Does sclerotherapy hurt?
Because this procedure requires injections through the skin, it is not a painless procedure. Certain chemicals that are injected (sclerosants) are more likely to cause pain than others. If the sclerosant is deposited outside the vein inadvertently, this is often more painful.
Is sclerotherapy an effective treatment for varicose veins and spider veins?
Sclerotherapy is an effective technique to obliterate or collapse veins. Other techniques include surgical removal of the offending vein, endovenous laser destruction (fiberoptic-transmitted laser light) and, for very small vessels, percutanous laser light or intense pulsed-light exposure are also effective.
Who is a good candidate for sclerotherapy?
Those with venous insufficiency who have disease that is poorly controlled with compression stockings and who are not obese are ideal candidates for sclerotherapy. To determine if sclerotherapy obliteration is likely to be of benefit, the site of the defective vein is identified as well as the venous drainage pattern. Healthy people who complain of unsightly superficial veins of small caliber (4 mm or less) are also candidates for sclerotherapy.
How do people prepare for the sclerotherapy procedure?
Patients are screened using special ultrasound techniques to determine the site of venous disease prior to treatment. In situations where there is only a small area of spider veins, this is rarely done.
How are sclerotherapy injections administered?
There are now two FDA-approved sclerosants available, sodium tetradecyl sulfate (a detergent) and polidocanol (Asclera). For small veins, hypertonic saline is occasionally used. Depending on the size of the vein to be treated, the sclerosant may be administered as foam. A needle of the appropriate caliber is inserted into the vessel to be treated, and the chemical is injected.
What is the recovery time for sclerotherapy?
This is an outpatient procedure and the patient leaves the office on the same day of treatment.
What aftercare is needed following a sclerotherapy procedure?
Patients should wear compression dressings for one to three weeks after treatment. A follow-up visit within two weeks to enable the evacuation of blood clots in larger veins can improve the prognosis and the appearance.
What are the benefits of sclerotherapy?
For patients with venous insufficiency, treatment can be beneficial by improving venous blood flow and limiting chronic swelling. For those with cosmetic complaints, their appearance can be improved.
What are risks, side effects, and complications of sclerotherapy?
Sclerotherapy risks, side effects, and complications include hyperpigmentation, temporary swelling, capillary dilation (telangiectatic matting), pain from the injection, localized hives, tape compression blister, tape compression folliculitis, and recurrence, vasovagal reflex, localized hair growth (hirsutism), skin death (cutaneous necrosis), allergic reaction, superficial thrombophlebitis, arterial injection, pulmonary embolism, deep vein thrombosis, nerve damage, and migraine headaches.
Does insurance cover the cost of sclerotherapy?
Although insurance companies differ in their coverage and preapproval is always helpful, the treatment of venous insufficiency is usually covered. The treatment of cosmetic problems including spider veins is rarely covered.

AllergyAn allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Birthmarks and Other Skin Pigmentation ProblemsBirthmarks and other abnormal skin pigmentation is caused by the body's inability to produce enough melanin. Abnormal skin pigmentation can cause conditions such as vitiligo, pigmentation loss, melasma, albinism, port wine stains, macular stains and hemangioma.
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include
- high blood pressure and cholesterol,
- smoking, and
- family history.
Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Deep Vein Thrombosis
Deep vein thrombosis (DVT) is a blood clot in the deep veins, and can be caused by broken bones, trauma to a limb, immobility, medications, smoking, cancer, genetic predisposition, and cancer. Symptoms of a deep vein thrombosis in a leg are
- warmth, and
Treatment for DVT include medications and surgery.
FolliculitisFolliculitis is a skin condition that causes small red bumps to form around the hair follicles. Skin bacteria such as Staphylococcus and Pseudomonas may infect the follicles. Treatment involves over-the-counter bacterial washes, topical antibiotics, and/or topical steroids.
HivesHives, also called urticaria, is a raised, itchy area of skin that is usually a sign of an allergic reaction. The allergy may be to food or medications, but usually the cause of the allergy (the allergen) is unknown.
ItchItching can be a common problem. Itches can be localized or generalized. There are many causes of itching to include: infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.
Pulmonary EmbolismA pulmonary embolism (PE) occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery in the lung where it blocks the artery and damages the lung. The most common symptoms of a pulmonary embolism are shortness of breath, chest pain, and a rapid heart rate. Causes of pulmonary embolism include prolonged immobilization, certain medications, smoking, cancer, pregnancy, and surgery. Promt medical attention should be sought if you think you or someome you know has a pulmonary embolus.

- heart valve irregularities,
- carotid artery disease,
- heart disease,

Varicose VeinsVaricose vein: A dilated (widened) tortuous (twisting) vein, usually involving a superficial vein in the leg, often associated with incompetency of the valves in the vein. These visible and bulging veins are often associated with symptoms such as tired, heavy, or aching limbs. Spider veins are a group of widened veins that can be seen through the surface of the skin.
