Interventional Neuroradiology

Interventional neuroradiology (INR) is a subspecialty of radiology that deals with the minimally invasive treatment of brain and spinal cord conditions through an endovascular approach.  Utilizing sophisticated imaging technology (such as x-rays, ultrasounds, MRIs and CT scanning), physicians thread catheters through the groin into blood vessels in the spinal column or brain to deliver treatment.  These procedures are often preferred over surgery because they do not require a large incision, often pose less risk and have faster recovery times. 

Because your recovery is our top priority, our interventional neuroradiologists work closely with our neurosurgeons and other specialists to determine whether endovascular intervention, surgery or other medical treatment is the best option for your individual diagnosis.

Diseases and conditions that can be treated through INR include:

  • Brain aneurysms
  • Brain arteriovenous malformations (AVMs)
  • Carotid-cavernous fistulae
  • Dural arteriovenous fistulae
  • Extracranial (brachiocephalic) atherosclerosis
  • Extracranial (head and neck) and paraspinal vascular malformations
  • Vertebral body compression fractures
  • Head and neck tumors
  • Intracranial atherosclerosis
  • Juvenile nasopharyngeal tumor
  • Meningiomas
  • Nosebleeds
  • Paragangliomas
  • Stroke
  • Spinal vascular malformations
  • Traumatic vascular lesions
  • Vasospasm
  • Vertebral body tumors

Procedures performed by an interventional neuroradiologist include:

  • Drug infusion – for the treatment of spasms and vasculitis
  • Endovascular coiling - minimally invasive treatment of aneurysms that produces better patient outcomes with the latest embolization products and techniques
  • Percutaneous transluminal angioplasty – (in the head, neck or spine) to improve blood flow, make the artery smoother and decrease the chance of stroke
  • Stent placement – (in the head, neck or spine) to improve blood flow, make the artery smoother and decrease the chance of stroke           
  • Thrombectomy – removal of blood clots for the treatment of stroke.  State-of-the-art devices utilized include:
    • Penumbra System® – allows for rapid clot extraction and revascularization of the blood vessel
    • Merci Retrieval System® - used to remove or break up blood clots
