Foam Sclerotherapy Treatment

The doctors at Vaughn Vein Clinic also use foam sclerotherapy to treat varicose veins, sometimes in addition to EVLT. It is performed without sedation in a doctor’s office and has a minimal recovery time.

While foam sclerotherapy and EVLT are both used to treat varicose veins and other venous disorders or diseases, the technique involved is very different. Like EVLT, foam sclerotherapy incites an inflammatory reaction within the vein. However, foam sclerotherapy involves the doctor injecting the vein with a foam substance (a mix of a chemical and a gas) that the causes the vein to scar inside and constrict (preventing blood flow) so that it eventually disappears. Foam sclerotherapy is different than more traditional liquid sclerotherapy used to treat smaller veins, such as spider veins. Because the sclerosant is thicker, it does not mix with blood but displaces it.

Sclerotherapy treatment for varicose veins has been used for over 150 years. Due to medical complications and high rates of side effects with the drugs used at the time, the practice was largely abandoned by the early 1900’s due to improvements in surgical techniques. Ligation and stripping became the treatment of choice until continued work on perfecting foam sclerosants was met with ultrasound technology in the 1980’s and the evolution of EVLT.

Side effects of foam sclerotherapy may include allergic reaction to the sclerosant, swelling, itching and skin pigment changes in the treated area. Sclerotherapy is also used to treat spider veins but a different type of sclerosant is used.

Many people suffer from both small and medium-large varicose veins and will require both EVLT and sclerotherapy treatments. Luckily these procedures are both minimally invasive and do not take long to perform, often making them easy to pair up into one trip to the doctor.


Vein Disorders

Varicose veins are a result of pressurization of small veins located below the skin. The cause of this pressurization is incompetent valves within veins themselves. This does not allow the normal antegrade (forward) flow...
