Brain Aneurysm and Hemorrhage

The team of cerebrovascular doctors at Mischer Neuroscience Institute provides coordinated care for patients with aneurysms, carotid occlusive disease, arteriovenous malformations and other intracranial vascular malformations.

Cutting-edge endovascular suites feature the latest technology for treating both stroke and aneurysm, including the Siemens Artis™ zee biplane system. Procedures include angioplasty, stenting and embolization. Radiosurgery is also available for vascular malformations.

Neurosurgeons affiliated with MNI are highly skilled in treatment options including resection, clot retrieval, hemicraniectomy for severe strokes, microvascular clipping of aneurysms, endovascular embolization, extracranial-intracranial bypass and carotid endarterectomy.

Also available is a new type of endovascular flow-diverting stent, called a pipeline embolization device, that reconstructs the lumen of the aneurysm’s parent artery in areas that are difficult to reach surgically, as an alternative to clipping or endovascular coiling.

Physicians at Mischer Neuroscience Institute are among the best in the nation. Our arteriovenous malformation outcomes are continually better than national benchmarks, and we are dedicated to providing the highest level of care to each of our patients.

Brain Aneurysm Prevalence

It is estimated that one in every 50 people in the United States suffers from an unruptured brain aneurysm, while an average of 30,000 people suffering from a rupture annually. Ruptured brain aneurysms are fatal in about 40 percent of cases. Of those who survive, about 66 percent suffer some permanent neurological deficit.

Genetic Factors and Risk

Even though most brain aneurysms cause no symptoms and may only be discovered during tests for another, usually unrelated condition, researchers have discovered genetic factors that could help doctors identify people who are at the greatest risk for developing a brain aneurysm.

Some studies show that first-degree relatives of people who suffered aneurysmal hemorrhage are more likely to have aneurysms themselves. These studies also reported that such immediate family members were four times more likely to have aneurysms than the general population.
