Sclerotherapy works by using a special sclerosing solution, which is injected directly into the affected veins. This solution, often a saline or a detergent-like agent, irritates the inner lining of the targeted veins.
After the injection, the irritation causes the vein walls to become inflamed, leading to a response from the body that initiates the healing process. This inflammation prompts the vein to collapse and seal shut, effectively closing off the blood flow within that vein.
As a result, the body begins to reabsorb the now-closed vein over time, a process that can take several weeks to months. The treated vein gradually fades from view, becoming less noticeable as the surrounding tissue heals.
Additionally, because blood is redirected to healthier veins, the overall circulation in the area can improve, alleviating any symptoms associated with varicose veins, such as discomfort and swelling. This method is highly effective, and many patients experience significant improvement in both the appearance and symptoms of their veins after treatment.
