Interventional neuroradiology

Interventional neuroradiology (also known as endovascular neurosurgery or neurointerventional surgery) is a medical specialty that uses minimally invasive, image-guided techniques to diagnose and treat diseases of the central nervous system, head, neck, and spine. The field is a subspecialty of radiology, neurology, and neurosurgery.

History

Interventional neuroradiology originated in the 1960s with the introduction of angiography, a technique for imaging blood vessels. The field has since expanded to include a wide range of procedures, including embolization, stenting, and thrombolysis.

Procedures

Interventional neuroradiologists perform a variety of procedures, including:

• Angiography: This diagnostic procedure uses X-rays and a special dye to see inside the blood vessels.
• Embolization: This treatment procedure involves blocking a blood vessel to prevent blood flow to a certain area of the body.
• Stenting: This procedure involves placing a small, metal mesh tube inside a blood vessel to prevent it from closing.
• Thrombolysis: This treatment procedure involves dissolving blood clots.

Training and Certification

Training in interventional neuroradiology typically involves a fellowship following completion of a residency in neurology, neurosurgery, or radiology. Certification is offered by several professional organizations, including the American Board of Radiology and the American Board of Neurological Surgery.
