ARTERIOVENOUS MALFORMATIONS AVM Incidence Since only 12% of AVMs cause symptoms, the incidence of AVM in the United States is not fully known. The incidence is thought to be around 1 per 100,000, equaling 300,000 cases. As technology advances and early detection increases, these numbers may rise.

Th e prevalence is calculated 0.2-0.5%/100.000 although lower numbers are discussed (0.01%) Men are slightly more aff ected than women (1.4:1) [1]. Most patients present with the neurological sequelae of intracranial haemorrhage caused by the AVM (50%), which is a major cause of intracerebral bleeding in younger adults. In 25% patients present with epileptic seizures and in 25% with other sympt...
