This recently expanded program focuses on the entire spectrum of neurovascular diseases- (1) prevention and reduction of risk factors, (2) acute intervention with thrombolysis, endovascular therapy, and neurovascular surgery, (3) neurocritical care, and (4) rehabilitation. On the frontline of clinical research, the program is conducting trials of new drugs to prevent brain injury during stroke and prevent recurrent stroke. The Stroke Center maintains a skilled team of stroke neurologists, 24/7, who are available to respond to emergencies and administer thrombolytic drugs (rTPA) according to the most advanced protocols. State-of-the-art imaging is on site, including CT, MRI, MR angiography, CT perfusion/angiography, neurovascular ultrasound, and PET. The most advanced endovascular devices are used, including the MERCI (Concentric, Inc.) mechanical clot extractor, and coil and glue embolization for brain aneurysms and arteriovenous malformations (AVMs). The Division collaborates with neurosurgery, interventional neuroradiology, emergency medicine, and rehabilitation medicine in providing treatments for all types of neurovascular disorders, including carotid and vertebral artery stenosis, brain aneurysms and AVMs, brain hemorrhage, and transient ischemic attacks (TIAs).
