Interventional neuroradiology is a subspecialty of interventional radiology which involves using medical imaging tests in diagnosing and treating diseases of the central nervous system, head, neck and spine.

Interventional neuroradiologists use cutting edge imaging and guidance techniques to guide catheters (very fine plastic tubes) and other tiny instruments around the arteries and veins in the head, neck or spine to treat conditions such as strokes or aneurysms.

Treatment is minimally invasive and avoids the need for traditional surgery. This lowers the risk to patients, shortens the time spent in hospital and reduces recovery time.

Interventional neuroradiology is used to treat:

  • Head, neck and spinal tumours through embolization (injecting medical grade ‘glue’, special tiny coils or sand-like particles into the blood vessels of a tumour)
  • Intracranial brain aneurysms

Essentially, interventional neuroradiology therapies are accomplished through microcatheters inserted in the groin area and, under X-ray guidance, threaded through the blood vessels leading into the brain.

Interventional neuroradiologists currently employ minimally invasive procedures to accomplish a wide variety of treatments including: stroke treatment by delivering clot-busting drugs directly to the site of the blockage; aneurysm therapy by inserting platinum coils into the aneurysm bulge to prevent clotting and rupture; and spinal treatments by injecting cement into a fractured vertebra in order to reinforce the bone.
