Our Leading-edge Treatments

We are consistently among the first to use leading-edge neurovascular treatments and technologies that include the following:

Brain aneurysm coil treatment: If it is determined during an angiogram that coils are necessary, neurointerventional radiologists deploy multiple coils in the affected area until progressive occlusion is achieved. The minimally invasive treatment can also be used after a rupture.

Advancements in aneurysm clipping: Riverside Neuroscience Institute physicians use Integrated Neurovascular Fluorescence in aneurysm clipping. The technique allows the surgeon to view neurovascular blood flow, while still looking through the operative microscope, and immediately assess whether clipping of the aneurysm is complete or incomplete.

Onyx® liquid embolism: Riverside Neuroscience Institute uses Onyx HD-500 in the treatment of a complex aneurysm. This minimally invasive treatment was granted a Humanitarian Device Exemption by the FDA. RNI's Neurovascular Center also uses Onyx 18 and Onyx 34, which are FDA approved for the treatment of vascular malformations.

Our Leading-edge Neurovascular Stroke Treatments

Our neurointerventional radiologists play a critical role in the care and treatment of stroke patients, using a variety of leading-edge treatments that include:

MERCI Clot Retriever: The MERCI is a corkscrew-like coil the neurointerventional radiologist uses to remove an ischemic stroke clot, oftentimes instantly reversing the course of a stroke.

Aspiration: The Penumbra Stroke System uses aspiration and catheterization techniques to rapidly restore blood flow in the brain and limit damage caused by stroke. Our physicians were among the first in the nation to test the Penumbra Stroke System and have seen it help patients completely recover from a devastating stroke.

Stents: Our highly trained physicians use the Wingspan™ Stent System and the Gateway™ PTA Balloon Catheter to open narrowed arteries deep in the brain, resulting in a dramatically lower risk for stroke. In addition, we use the following, all of which were granted Humanitarian Device Exemption status by the FDA:

  • Wingspan HDE Safety Study
  • Neuroform3™ Microdelivery Stent System
  • CORDIS ENTERPRISE™ Vascular Reconstruction Device and Delivery System

tPA (Tissue Plasminogen Activator): Typically, tPA can be administered intravenously within four-and-a-half hours of a stroke's onset. Riverside Neuroscience Institute physicians have developed new techniques extending the tPA treatment window to seven hours. The new technique delivers tPA superselectively to the clot via a microcatheter. This avoids or minimizes a more life-threatening stroke.

Superselective IA injection of vasodilators: Our Neuroscience Institute physicians superselectively inject vasodilators intra-arterially to manage cerebral vasospasm.

Our neurovascular team of experts provides an integrated, well coordinated continuum of care that is unsurpassed in the region.

We provide regional and national leadership in this field of advancing new technology and excellence in patient care services for you and your family.
