Treatment of vein disease used to be complex, with surgery once being the only option. The development of advanced minimally invasive techniques has dramatically changed the way vein conditions are treated. Today, managing vein disease is faster, safer, and simpler than ever before. Office-based procedures guided by ultrasound have been shown to deliver excellent results for patients.
Sclerotherapy is a procedure that involves injecting a medication, known as a sclerosant, into an unhealthy vein. The sclerosant gently damages the vein wall, causing it to stick together and eventually close. As a result, blood flow is redirected to healthier veins, improving overall circulation.
This treatment is commonly used for spider veins and varicose veins. Sclerotherapy is an effective option for both small spider veins and larger varicose veins.
During sclerotherapy, the affected leg is elevated to empty the vein. The vein doctor then injects a sclerosant into the varicose or spider veins using a very fine needle. Only FDA-approved sclerosants are used. After the injection, compression stockings are applied to prevent blood from pooling in the treated vein when standing.
The sclerosant damages the inner lining of the vein, causing it to collapse and close. Over time, the vein is replaced by scar tissue and gradually fades from view.
The procedure is typically performed in a clinic or doctor’s office and takes about 10 to 30 minutes, depending on the number and size of veins treated. Patients are usually advised to wear medical-grade compression stockings for several days after treatment.
Sclerotherapy generally requires only one injection per vein and is considered minimally painful. A mild cramping or burning sensation may be felt at the injection site. Depending on the severity of the condition, multiple sessions may be needed.
Superficial veins are treated under direct visualization, while deeper veins may require ultrasound guidance to ensure accurate delivery of the medication.
The main benefit of sclerotherapy is that it does not require surgery, extensive preparation, or a long recovery period. The procedure is performed in-office and typically does not require anesthesia. Another advantage is that it can be completed in 30 minutes or less. Most patients can return to their normal daily activities immediately after treatment, with no downtime needed.
However, no treatment is perfect, and sclerotherapy is not suitable for everyone. One limitation is that it may not be effective for all patients. It is most commonly used for smaller varicose veins and spider veins. In cases of larger varicose veins, it may need to be combined with other treatments such as radiofrequency ablation or VenaSeal to achieve optimal results.
There are two types of sclerotherapy: liquid sclerotherapy and foam sclerotherapy. Treatment is customized for each patient based on vein size, treatment goals, and the extent of vein disease.
Liquid sclerotherapy is typically used for very small spider veins, where a liquid medication is injected directly into the vein.
Foam sclerotherapy, on the other hand, is preferred for larger varicose veins. It involves mixing a small amount of liquid medication with air to create a foam-like substance. The bubbles allow the medication to spread over a larger surface area, making it more effective for treating larger veins.
