The team of cerebrovascular doctors at Mischer Neuroscience Institute provides coordinated care for patients with aneurysms, carotid occlusive disease, arteriovenous malformations (AVMs) 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 – an advanced imaging tool that is designed for mapping structural heart diseases. Procedures include angioplasty, stenting and embolization. Radiosurgery is also available for vascular malformations.

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, with an average of 30,000 people suffering from a rupture annually. Ruptured brain aneurysms are fatal in about 40% of cases. Of those who survive, about 66% 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.

Brain Aneurysm Treatment

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

Endovascular Care

Through a collaborative effort between the Memorial Hermann Mischer Neuroscience Institute at the Texas Medical Center and McGovern Medical School at UTHealth, Mischer Neuroscience Associates (MNA) extends its endovascular expertise and capabilities to several key suburban locations, including Memorial Hermann Memorial City Medical Center, Memorial Hermann The Woodlands Medical Center, and Memorial Hermann Southwest Hospital.

Endovascular Services Close to Home

At each of the three new locations, MNA provides care for patients under treatment for cerebrovascular disorders, offering referring physicians access to diagnostic angiography and endovascular services in the Greater Houston area. Through MNA’s affiliation with the Mischer Neuroscience Institute, more acute patients can be transferred to Memorial Hermann-Texas Medical Center for complex care.

This partnership between campuses provides referring physicians with access to the full spectrum of endovascular services, from diagnostic angiography to endovascular surgery for complex conditions of the brain, including aneurysms, stroke, arteriovenous malformations, and subarachnoid and intracranial hemorrhage. The result is a multicenter, coordinated endovascular program focused on getting the right patients to the right hospital, depending on their needs, as well as specialized services close to home.
