Ultrasound Guided Sclerotherapy

Ultrasound Guided Sclerotherapy

Ultrasound-Guided Sclerotherapy (UGS) involves injecting a sclerosing agent, usually a liquid or foam, directly into the affected veins under ultrasound guidance. The sclerosing agent irritates the inner lining of the vein, causing it to collapse and eventually be reabsorbed by the body. Over time, the treated vein fades away, and blood is rerouted to healthier veins.

• Foam sclerosant is injected into the refluxing small to medium varicose veins.
  
• The lining of the vein is damaged; causing inflammation, scarring and is eventually absorbed.
• Ultrasound is used to find a suitable site of injection of the foam liquid sclerosant.
• The column of foam from the sclerosant displaces the blood and injures the lining of the vein.
  
• The damage of the endothelium leads to spasm of the vein and initiates the body’s wound healing response of inflammation, resulting in subsequent complete obliteration of the vein.
