Saphenous vein ablation for the minimally invasive treatment of varicose veins

Saphenous foam ablation, also known as ultrasound-guided foam sclerotherapy, is a minimally invasive treatment for varicose veins. The procedure involves injecting a specialized medicated foam into the diseased saphenous vein, causing it to spasm, collapse, and seal closed. By closing the faulty vein, blood is redirected to healthier veins, improving circulation and reducing symptoms.

Using ultrasound imaging, Dr. Vrabec carefully identifies the affected vein and precisely guides the needle to ensure accurate placement of the foam. The treatment solution begins as a liquid sclerosant that is mixed with air or carbon dioxide to create a dense foam. This foam is more effective than a liquid alone because it fills the entire vein cavity and displaces blood, allowing direct contact with the vein wall rather than becoming diluted.

Once injected, the foam irritates the inner lining of the vein, causing immediate contraction (vasospasm) and triggering the vein walls to adhere to each other. Over time, the sealed vein turns into fibrous tissue and is gradually absorbed by the body. As the treated vein closes, blood flow naturally reroutes to healthy, deeper veins, restoring more efficient circulation and reducing the appearance and discomfort of varicose veins.
