Arteriovenous Malformations

An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins of the brain. This is a condition that is usually present from birth and may cause headache, seizure, or bleeding into the brain (hemorrhage). The treatment of AVMs can include surgery, radiosurgery, or embolization.

Hemorrhagic Stroke

A hemorrhagic stroke is the accumulation of blood anywhere within the skull vault.

Intracranial Aneurysm

An aneurysm represents a weak spot in the wall of an artery which results in a "focal bulge" or widening of the artery. In the brain, these aneurysms have a 2-4% annual risk of rupture which can result in "subarachnoid hemorrhage", or bleeding in the space around the brain.

Ischemic Stroke

An ischemic stroke (cerebral infarction) occurs when a blood vessel that supplies a part of the brain becomes blocked. This loss of blood supply results in the death of brain tissue in that area. Cerebral infarctions vary in their severity with one third of the cases resulting in death.
