My friend (and client), Jeremy, recently came out of brain surgery for a cerebral arteriovenous malformation (AVM).

He’s now sporting a pretty wicked scar from the event and was kind enough to share it with us.

An AVM is an abnormal connection between the arteries and veins in the brain.

The most frequently observed problems related to an AVM are headaches and seizures, but at least 15% of the population at detection have no symptoms at all.

Jeremy had no idea he had an AVM until a seizure whilst on holiday.

Other common symptoms are a pulsing noise in the head, progressive weakness, numbness, vision changes, as well as debilitating, excruciating pain. In serious cases, the blood vessels rupture and there is bleeding within the brain.
