Sclerotherapy (SKLER-o-ther-a-pee) is the most common treatment for both spider veins and varicose veins. A doctor uses a needle to inject an FDA-approved liquid chemical into the damaged vein. The chemical causes the vein walls to swell, stick together, and seal shut. This stops the flow of blood. The vein shrinks over time and is eventually absorbed. In a few weeks, the vein fades away.This outpatient treatment is performed by interventional radiologists at our Vein Center located in our Cary, NC office. Contact us today to schedule a vein consultation.

Post Treatment Info

Sclerotherapy does not require anesthesia. You can return to work and resume normal activity immediately after treatment.While some veins will resolve with just one treatment, others will require additional treatments to go completely away. Your doctor may recommend that you wear gradient compression stockings after sclerotherapy to help with healing and decrease swelling.

Possible Side Effects

While sclerotherapy is considered very effective when done correctly, possible side effects include:

  • Stinging, red and raised patches of skin, or bruises where the injection was made. These usually go away shortly after treatment.
  • Spots, brown lines, or groups of fine red blood vessels around the treated vein. These also usually go away shortly after treatment.
  • Lumps of blood trapped in the vein may cause inflammation. This is not dangerous and can be relieved by applying heat and taking aspirin. Your doctor can drain the trapped blood with a small pinprick at a follow-up

Ultrasound-Guided Sclerotherapy

This type of sclerotherapy, sometimes called echo-sclerotherapy, uses ultrasound imaging to guide the needle. This approach can be useful when treating veins that aren’t visible on the skin’s surface. It may be used after other endovenous techniques if the varicose veins return.This procedure can also be done in our Vein Center in Cary, NC.
