Arteriovenous Malformation (AVM)
Beginning in the late 1980's, surgical intervention for arteriovenous malformation, or AVMs, was facilitated by embolization using substances such as polyvinyl alcohol. As with brain tumors, this decreased the amount of bleeding seen at the time of surgery. However, since AVM's carry a particularly large amount of high pressure blood flow, the risk of blood loss can be prohibitive, rendering many large lesions inoperable. At CNI, Dr. Yakes has pioneered a new type of treatment that infuses the AVM with absolute ethyl alcohol. This has resulted in immediate sclerosis of the embolized vessels. In lesions in which he has been able to obtain a complete radiographic obliteration of the lesion, he has experienced at 69% cure rate. This type of treatment has not been duplicated elsewhere. Dr. Yakes has been invited to many destinations around the globe to educate others about this technique. Learn more.
