Neurovascular Conditions

The following are a few of the conditions that can be treated by the new procedures at the Providence Neurovascular Institute:


A stroke is the sudden interruption of blood flow or hemorrhage of a blood vessel in the brain. Symptoms include sudden numbness and/or weakness on one side, sudden confusion or trouble speaking, vision problems, dizziness, loss of balance and/or coordination, and sudden severe headache pain. One of every 18 deaths is the result of a stroke, a death every 40 seconds. Approximately 795,000 Americans suffer a new or recurrent stroke each year.

Cerebral Aneurysms

Cerebral aneurysms are caused by the ballooning out of an artery in the brain. Ten out of every 100,000 persons will have an aneurysm rupture, leading to bleeding in the brain that can lead to stroke, coma or death. Aneurysms may have no symptoms until they rupture, and can occur at any age, although they are more common in adults, and in women more than men.

Cerebral Vasospasm

Vasospasm is a constriction of the blood vessels in the brain common following bleeding from a cerebral aneurysm that may lead to stroke or death.

Arterial Malformations (AVMs) and Dural Fistulas

AVMs and dural fistulas are abnormal connections between arteries and veins. Symptoms can occur at any age and include headache, decreased sensation in any part of the body, muscle weakness, seizures and vision changes. They may also result in devastating or life-threatening brain bleeding. Of the 300,000 Americans who have AVMs, only 12 percent will have symptoms.

Cerebral, Carotid or Vertebral Stenosis

A stenosis is the narrowing of an artery from the build-up of deposits that block blood flow in the brain, causing a stroke or temporary neurological deficit.


Tumors are caused by abnormal, rapid cell growth. When tumors occur in the brain, symptoms can include headaches, seizures, vomiting, nausea, vision or hearing problems, behavioral changes and motor problems.
