Neurointerventional Surgery
What is Neurointerventional Surgery?
Neurointerventional Surgery, Interventional Neuroradiology, or Endovascular Neurosurgery, is a subspecialty combining minimally invasive techniques in Radiology and Neurosurgery to treat vascular conditions of the central nervous system — the brain, spinal cord, head and neck. Our experienced Neurointerventional Surgeons are certified by the American Board of Radiology and considered international experts in the field. They have performed thousands of minimally invasive procedures and collaborate to provide excellent patient care.
We are Northern Virginia’s leaders in Neurointerventional Surgery, offering new therapies and technologies to treat even the most complex cases. Our goal is to provide you with exceptional service and the most advanced, evidence-based medical care available – delivered in a welcoming, friendly environment.
