Venous Sclerotherapy Procedures

Venous sclerotherapy is a safe, minimally invasive medical procedure used to treat spider veins and small varicose veins by injecting a special chemical solution into the affected blood vessel to close it off.
How Do Venous Sclerotherapy Procedures Work?
Sclerosant Injection
A doctor uses a tiny needle to inject a liquid or foam medicine (called a sclerosant) right into the bad vein.
Veinous Irritation
This medicine irritates the inside lining of the vein and makes it swell shut.
Blood Flow Redirection
Blood stops flowing through that useless vein and moves to healthier veins nearby.
Absorbtion
Over a few weeks or months, your body safely absorbs the closed vein and it fades away.
What are Venous Sclerotherapy Procedures For?
Spider Veins
Fades tiny, visible red, blue, or purple sunburst patterns on the surface of the skin (most commonly on the legs) for cosmetic improvement.
Varicose Veins
Collapses enlarged, twisted superficial veins to relieve physical discomfort like aching, swelling, burning, cramping, and heaviness in the legs.
Blood Flow Improvement
Redirects blood circulation from damaged, pooling vessels into healthier, deep-pathway veins
What are the Benefits of Venous Sclerotherapy Procedures
Procedural advantages
Minimally invasive: It's an in-office procedure with no need for anesthesia. Vein Heart and Vascular
No pain during the procedure: You shouldn't feel any pain during the procedure, though you may notice a burning sensation or mild itching for a few minutes afterward. Vein Heart and Vascular
No surgical removal needed: This procedure can effectively get rid of most varicose veins and nearly all spider veins without surgically removing the veins. Mass General Brigham
Quick recovery: You can resume regular activities soon after the procedure. Mass General Brigham
Office-based setting: Sclerotherapy offers substantial therapeutic benefits with a low complication rate and can frequently be performed in an office-based setting. NCBI
Cosmetic benefits
Reduces vein appearance: It's used to improve the cosmetic appearance of spider veins and treat small varicose veins in the legs. RadiologyInfo
High success rate: Each treatment session typically results in elimination of 50 to 80 percent of the injected veins. RadiologyInfo
Improves confidence and quality of life: Injection sclerotherapy provides notable cosmetic improvement by reducing the appearance of unsightly veins, enhancing patients' confidence and quality of life. NCBI
Symptom relief
Eases discomfort: It relieves symptoms associated with spider and varicose veins, including aching, burning, swelling, and night cramps. RadiologyInfo
Improves vascular health: It alleviates symptoms associated with venous insufficiency, such as pain, swelling, and discomfort, leading to improved overall vascular health. NCBI
Reroutes blood flow: It shrinks varicose veins until they disappear, and blood reroutes to healthier veins. Medical News Today
Clinical standing
First-line treatment: Sclerotherapy is a first-line treatment for varicose veins, which can be a sign of chronic venous insufficiency. It's the primary treatment for small varicose veins in the legs. Medical News TodayRadiologyInfo
Best for smaller veins: Sclerotherapy may be less effective on larger, bulging varicose veins, in which case a doctor might recommend an alternative like endovenous laser therapy. Mass General Brigham
Improved outcomes with foam: Foam sclerotherapy, in particular, is recognized for its improved outcomes compared to liquid sclerotherapy, though it may not match the long-term success rates of thermal ablation methods for thicker-walled veins. nih
Aftercare
Compression support: You'll typically leave with a compression bandage or compression sock, which helps promote blood flow and reduces swelling and pain, often worn for up to a week. Mass General Brigham
