Hi edward40,
I'm sorry to hear about your dad. The brain surgeon will be able to explain and show you exactly what artery the vascular surgeon is referring to and can then discuss treatment options. Here is some information on the Blood Supply of the Brain & Spinal Cord that you may find informative.
Best Regards,
Karen McPartland, RD
