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 Hospital, 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.
