Also known as Mechanochemical Ablation (MOCA), ClariVein is a minimally invasive treatment for chronic venous insufficiency and varicose veins. Unlike laser or radiofrequency ablation, ClariVein does not rely on heat to close unhealthy veins. Instead, it combines a rotating catheter with a specialized sclerosant medication to gently seal the vein from the inside.
The rotating wire creates controlled mechanical injury to the vein wall while the medication causes the vein to collapse and close. Blood is then naturally redirected through healthier veins, improving circulation and relieving symptoms such as leg heaviness, swelling, aching, and varicose veins. ClariVein may be recommended for selected patients based on ultrasound findings and their individual treatment needs. Treatment costs vary depending on your condition and insurance coverage.
After numbing the skin with local anesthesia, a ClariVein catheter is inserted through a tiny skin opening and guided into the unhealthy vein using ultrasound imaging. Once activated, the rotating tip gently irritates the vein wall while simultaneously delivering a sclerosant medication, causing the vein to seal shut and redirect blood to healthy veins with functioning valves.
The procedure is performed in our office and usually takes 10 to 30 minutes, depending on the size and number of veins being treated. Following treatment, your vein specialist will recommend wearing medical-grade compression stockings for several days to support healing and improve circulation. Most patients experience very little discomfort during the procedure and can return to normal daily activities immediately, with little to no recovery time.
ClariVein is performed through a single catheter insertion without the use of thermal energy, laser treatment, or medical glue, making it a comfortable option for many patients. The procedure is minimally invasive, typically takes 30–45 minutes, requires only local anesthesia, and is performed entirely in the office.
Most patients return to normal activities the same day with little or no downtime. While ClariVein offers many advantages, every patient is different. Our specialists carefully evaluate your vein condition and may recommend ClariVein alone or in combination with treatments such as radiofrequency ablation or VenaSeal to achieve the best long-term results.
