Neurological disorders can be complex in nature – but fortunately, their treatment doesn’t have to be. The Valley Hospital’s neurointerventional team offers simplified and effective solutions for these intricate conditions. 

Using minimally invasive techniques and advanced technologies, our neurointerventional specialists offer sophisticated care that can return patients to healthy, active lives sooner. 

The Valley Approach to Neurointerventional Care

At The Valley Hospital, neurointerventional procedures are performed in an advanced neurointerventional suite. For many patients, an interventional procedure can replace extensive neurosurgery, resulting in a shorter hospital stay, quicker recovery time, reduced pain and less risk of complications. Patients continue to receive attentive care after their procedure in Valley’s dedicated Neuro Intensive Care Unit.

Our neurointerventional specialists also recognize that no progress happens without research. In an effort to constantly improve their treatment of patients, they participate in national and international clinical trials for the treatment of acute stroke.

  • Moya moya disease
  • Stroke

Neurointerventional Procedures


A cerebral angiogram is a diagnostic procedure used to detect neurological conditions before neurointerventional treatment is performed.


An embolization is a nonsurgical procedure performed to prevent abnormal blood flow to blood vessels or aneurysms. Embolizations can keep aneurysms from bursting, block blood flow to a tumor, and restore normal blood flow. Some types of embolizations can treat aneurysms that were once considered inoperable, offering truly lifesaving care. 

Types of embolization procedures include:

  • Coil embolization
  • Pipeline embolization
  • Onyx liquid embolization
  • Tumor embolization
  • Epistaxis embolization

Stroke Procedures

Neurointerventional devices and minimally invasive procedures used to treat strokes at Valley include:

  • Solitaire device – Used to restore blood flow to the brain in patients who have an acute ischemic stroke by mechanically removing blood clots from the brain. Valley was one of the first hospitals in the nation to use this technology.
  • Trevo® Pro Retrieval System – Used to quickly restore blood flow in patients experiencing an ischemic stroke through the use of a microscopic balloon-guide catheter and fluoroscopic imaging.
  • Penumbra suction device
  • Mechanical thrombectomy – Used to remove large blood clots by sending a wire-caged device, called a silent retriever, to the site of the blocked blood vessel in the brain, where a stent opens and grabs the clot. This procedure can be done within six hours of acute stroke symptoms. 


Stenting, also known as angioplasty, is a minimally invasive non-surgical technique used to open narrowed or blocked blood vessels of the brain. A tiny mesh wire tube, called a stent, is placed to help open the blocked vessel, which restores blood flow through the carotid or vertebral arteries, and ultimately reduces or removes the risk of stroke. Stenting can be performed to treat intracranial stenosis or atherosclerosis, extracranial atherosclerosis, and carotid artery disease.

Biplane Angiography System

Valley’s biplane angiography system, housed within a hybrid operating room, is used to diagnose neurological abnormalities by producing highly detailed, three-dimensional views of blood vessels leading to the brain and deep within the brain. It is also used to treat these abnormalities using minimally invasive techniques. 

Valley’s biplane system also produces images simultaneously from two regions of the patient’s head, from front to back and from side to side. This reduces the amount of contrast material required, improves visualization for diagnostic and therapeutic procedures, and shortens the time it takes to complete a neurological angiogram.

If an open procedure becomes necessary, the hybrid operating suite can be easily transformed for open neurosurgical procedures without moving patients and scheduling additional surgery.
