Stroke, Neurointervention and Critical Care

This division is a subspecialty field of medicine that combines highly specialized skills from the disciplines of Neurology, Neurosurgery, and Neuroradiology to offer minimally invasive therapies for disorders of the brain and spine. The team here at Froedtert and The Medical College of Wisconsin in Milwaukee serves patients with brain aneurysms, arteriovenous malformations (AVM), dural arteriovenous fistulas (dAVF), carotid stenosis, stroke, and other disorders of the blood vessels of the brain and spine. Modern stroke care requires that physicians with special expertise make rapid determinations of a patient's status and of the optimal management. Treatment options vary from routine admission for observation and work-up to immediate intracranial thrombolysis. Our Division is fortunate to have several fellowship trained Neurologists specializing in stroke and both Neurointensive and Neurointerventional care, who can provide state-of-the-art treatments. The clinical expertise assembled in the Department of Neurology had resulted in JCAHO certification of Froedtert Hospital as the first Primary Stroke Center in Wisconsin in 2004.

  Our Team

The Division of Neurointervention at Froedtert Hospital and the Medical College of Wisconsin is home to four neurointerventionalists with training in Neurology, Neurocritical Care, Vascular Neurology, and Endovascular Surgical Neuroradiology. The group provides consultation, evaluation, and follow-up for patients with a broad range of neurovascular conditions including those amenable to minimally invasive image-guided and catheter-based therapies. Located in Wisconsin’s largest academic health center, The Milwaukee Regional Medical Center, the Division of Neurointervention has become a leading referral center for neurovascular care in the Midwest. Extensive participation in landmark national clinical trials has positioned the Division of Neurointervention at the forefront of emerging therapies that are advancing the field.

  Clinical Trials

Clinical research is essential to advancing healthcare by defining efficacy in treatments and discovering safer and more cost-effective methods of delivering care to patients. The members of the Division of Neurointervention at Froedtert and the Medical College of Wisconsin share this vision and strive to be leaders in clinical trials. The Division of Neurointervention has participated in design and enrollment in numerous national clinical trials evaluating neuroendovascular therapies and devices and has been a top enrollment center in several multi-center randomized trials.

Current enrolling trials include:

The THERAPY Trial: The Randomized, Concurrent Controlled Trial to Assess the Penumbra System’s Safety and Effectiveness in the Treatment of Acute Stroke: Keywords: Stroke, Intervention

Penumbra Separator 3D US 510k Trial: Keywords: Stroke, Intervention

ACE: An Aneurysm Coiling Efficiency Study of the Penumbra Coil 400 System: Keywords: Aneurysm, Coiling, Intervention

DIAS-4: A randomized, double-blind, parallel-group placebo-controlled phase III study to evaluate the efficacy and safety of desmoteplase in subjects with acute ischemic stroke: Keywords: Stroke, Intervention
