Sclerotherapy – used to treat varicose veins – it is a medical procedure

Sclerotherapy is a medical procedure used to treat varicose veins and spider veins. A drug is injected into the vessels, which causes them to narrow. It is suitable for most children and young adults with vascular or lymphatic malformations. In adults, sclerotherapy is often used to treat varicose veins.

Varicose veins differ in many ways from varicose veins. Varicose veins are larger – usually over a quarter of an inch in diameter, darker in color, and tend to dilate. Varicose veins also cause pain more often and are associated with more serious venous disorders.

The exact origin of the disorder is unknown, but reports have shown that heredity, pregnancy, hormonal changes, weight gain, or leg injuries can affect the appearance of spider veins. Spider veins occur in both men and women, but more often in women. Female hormones can play a role in their development. Puberty, oral contraceptives, pregnancy, or hormone replacement therapy may help. They can also occur after an injury or by wearing tight belts or stockings with elastic bands. Varicose veins are mainly due to genetic susceptibility.

During sclerotherapy, the doctor injects a solution into unsightly veins with a fine needle. This solution causes the blood in the veins to lose color. The veins stop appearing purple, red, or blue.

Sclerotherapy is performed by the doctor. In most cases, a sterile 23% sodium chloride solution mixed with lignocaine (a local anesthetic) and heparin is injected directly into the blood vessel using a very fine needle into a very fine needle. A lignocaine-free solution is available for people who are allergic to lignocaine. The number of varicose veins injected in a single session depends on the size and location of the veins and the patient’s general health.

A substance is injected which narrows the vessels in the malformation. The doctor uses the ultrasound to insert a needle into the defect, then injects a substance that shows up on an x-ray. This should show the size of the malformation and whether the blood vessels are connecting to large veins. The doctor can then inject the substance to narrow the vessels. This leads to the formation of blood clots and scar tissue in the malformation, which ultimately leads to gradual narrowing.

You may experience mild discomfort and cramps for 1 to 2 minutes when injecting larger varicose veins. The sclerotherapy itself takes about 30 to 45 minutes.

The real benefit of sclerotherapy is that it doesn’t interrupt your lifestyle much, is virtually painless, is extremely safe, has few complications, and can be done outside of the hospital without wasting time at work or during social or sports activities. Most treatments last 2 to 3 weeks.

We can expect a good result with an 80% to 90% improvement in the cosmetic aspect of the leg.


The risks of sclerotherapy include:

  1. The color of the skin changes along the treated vein. This is the most common side effect of sclerotherapy. It may take 6 to 12 months for the discoloration to disappear. In some people, this can be permanent.
  2. Recurrent varicose veins.
  3. Itching, bruising, pain and blistering when the veins have been treated.
  4. Scarring due to ulcers or death of tissue around the treated vein (skin or fatty necrosis) when sclerosant is injected outside a vein or sclerosant escapes through the wall of the vein. a weakened vein.
  5. A mild or severe (anaphylactic) reaction to sclera. (Severe reactions are very rare, but can be life threatening.)
  6. Blood clots or damage to the deep venous system
    The cost of sclerotherapy varies depending on the region, the doctor and the number of treatments needed. For more information on the cost of your sclerotherapy, please consult a doctor.
