In most cases, small varicose and spider veins tend to be unattractive cosmetic issues that can be easily treated with sclerotherapy. The procedure is minimally invasive and effective. A solution is injected into the veins, causing the walls of the blood vessels to collapse and seal, and blood flow is rerouted to healthier veins.

Diagnosis and Treatment

First, patients undergo a physical exam, provide their medical history, and have a Leg evaluation. Next, an ultrasound may be ordered to rule out underlying issues. If the ultrasound is performed, the interventional radiologist will evaluate the results. The last step is discussing treatment options.

Sclerotherapy is performed on an outpatient basis, taking about 30 to 40 minutes to complete. It often requires multiple treatments depending on the type, number, and size of veins treated.

There are two types of sclerotherapy, and both procedures use the same sclerosing agent. The difference is:

  • Sclerotherapy – is good for treating spider or small varicose veins.
  • Foam sclerotherapy – is effective for treating veins that are longer and larger, in the sclerosing solution is mixed with air until it is a similar to the consistency of shaving cream.

It is important for patients to understand, this procedure does not provide instant, but gradual results. Depending on the number of treatments required, it may take between two to three months for veins to show improvement. They need time to recover after the treatment.


Patients need to wear a compression hose following the procedure, but can resume normal daily activities immediately.
