Cerebral Arteriovenous Malformation (CAVM)

A cerebral arteriovenous malformation (cerebral AVM, CAVM, cAVM) is an abnormal connection between the arteries and veins in the brain—specifically, an arteriovenous malformation in the cerebrum.

The most frequently observed problems, related to an AVM, are headaches and seizures, backaches, neckaches and eventual nausea, as the coagulated blood makes its way down to be dissolved in the individual's spinal fluid. It is supposed that 15% of the population, at detection, have no symptoms at all. Other common symptoms are a pulsing noise in the head, progressive weakness and numbness and vision changes as well as debilitating, excruciating pain.
