What Are the Latest Advances in Sclerotherapy for Treating Varicose and Spider Veins?

Sclerotherapy in New London, MN - Bloom Medspa

Varicose and spider veins are common venous disorders affecting millions worldwide, often causing discomfort and aesthetic concerns. Traditional treatments, while effective, have seen significant advancements in recent years.

Sclerotherapy, a minimally invasive procedure, has been at the forefront of these developments. This article will explore the latest advances in sclerotherapy, highlighting how these innovations improve patient outcomes and expand treatment options. Whether you’re considering sclerotherapy for the first time or are looking for updated information, this guide will provide a comprehensive overview.

What is Sclerotherapy?

Sclerotherapy is a medical procedure used to eliminate varicose and spider veins. It involves injecting a solution called a sclerosant directly into the affected veins. The sclerosant irritates the lining of the blood vessel, causing it to collapse and eventually be reabsorbed by the body. This process redirects blood flow to healthier veins and results in the disappearance of the treated veins over time.

Sclerotherapy has been used for over a century, with significant advancements in technique and materials over the years. Initially, the procedure was limited by less effective sclerosants and a need for imaging guidance. However, continuous research and technological improvements have made modern sclerotherapy a highly effective and safe treatment for varicose and spider veins.

Latest Advances in Sclerotherapy

Improved Sclerosants

One of the most notable advancements in sclerotherapy is the development of more effective and safer sclerosants. Traditional sclerosants, such as hypertonic saline, were often associated with pain and side effects. Today, newer agents like polidocanol and sodium tetradecyl sulfate (STS) are widely used. These sclerosants are less painful upon injection and have a lower risk of complications, making the procedure more comfortable and safer for patients.

Polidocanol and Sodium Tetradecyl Sulfate (STS)

Polidocanol and STS are now considered the gold standards in sclerotherapy. Polidocanol, in particular, has gained popularity due to its anesthetic properties, which reduce discomfort during the injection. Both agents are highly effective at inducing vein sclerosis and have a favorable safety profile.

Foam Sclerotherapy

Foam sclerotherapy is another significant advancement that has revolutionized the treatment of larger varicose veins. Unlike traditional liquid sclerosants, foam sclerosants are created by mixing the sclerosant with air or gas, forming a foam. This foam displaces blood within the vein, allowing for greater contact between the sclerosant and the vein wall. As a result, foam sclerotherapy can treat larger veins more effectively with fewer injections.

Benefits of Foam Sclerotherapy:

  • Increased Efficacy: The foam’s ability to displace blood enhances the sclerosant’s action, leading to better treatment outcomes.
  • Reduced Dosage: Because the foam covers more surface area, a smaller amount of sclerosant is needed, reducing the risk of side effects.
  • Improved Visualization: Foam is more visible under ultrasound, allowing for more precise injections and better monitoring of the treatment process.

Ultrasound-Guided Sclerotherapy

The integration of ultrasound technology into sclerotherapy has been a game-changer, particularly for treating deeper and larger varicose veins that are not visible on the surface. Ultrasound-guided sclerotherapy allows physicians to visualize veins in real time, ensuring accurate placement of the sclerosant.

Advantages of Ultrasound Guidance:

  • Precision: Real-time imaging allows for precise injection of the sclerosant into the targeted vein, improving efficacy and reducing the risk of complications.
  • Accessibility: Ultrasound guidance makes it possible to treat previously difficult veins, expanding the range of treatable veins.
  • Safety: Enhanced visualization minimizes the risk of injecting the sclerosant into surrounding tissues or healthy veins.


Cryo-sclerotherapy combines traditional sclerotherapy with cryotherapy, where the treatment area is cooled before, during, and after the injection. This method has shown promise in reducing pain and improving patient comfort during the procedure.

Benefits of Cryo-Sclerotherapy:

  • Pain Reduction: The cooling effect numbs the treatment area, significantly reducing the pain associated with the injection.
  • Improved Patient Experience: Enhanced comfort can make the procedure more tolerable, particularly for patients with a low pain threshold.

Why Choose Sclerotherapy?

Sclerotherapy remains one of the most effective and versatile varicose and spider veins treatments. Its minimally invasive nature and the latest technological advancements make it an attractive option for many patients.

Minimally Invasive

Sclerotherapy is a minimally invasive procedure that does not require anesthesia or significant downtime. Patients can resume their normal activities shortly after treatment, making it a convenient option for busy people.

High Success Rates

With advancements like improved sclerosants, foam sclerotherapy, and ultrasound guidance, sclerotherapy boasts high success rates and excellent patient outcomes. Most patients experience significant improvement in the appearance and symptoms of varicose and spider veins.


Compared to surgical options, sclerotherapy is relatively cost-effective. The procedure is quick, and the need for multiple sessions is reduced with the latest advancements, further lowering overall treatment costs.
