Sclerotherapy is a minimally invasive, image-guided treatment that involves injecting a liquid medication into a vascular malformation to shrink and close it.

What conditions does sclerotherapy treat?

Sclerotherapy is most commonly used to treat vascular malformations (venous, lymphatic and arteriovenous). These are abnormal blood vessels or fluid-filled channels that can appear anywhere in the body and cause pain, swelling or other symptoms.

How does it work?

Sclerotherapy shrinks and closes vascular malformations by injecting them with a medication called a sclerosant. The sclerosant irritates the inside of the malformation, making it swell and close over time. Repeat procedures may be needed to close the malformation completely.
