Endovascular Brain Surgery (Neurointervention)

Endovascular brain surgery, or neurointervention, is a minimally invasive procedure that uses catheters inserted into a blood vessel, typically in the groin or wrist, to diagnose and treat conditions in the brain and spine.

Endovascular brain surgery is a highly specialised areas of neurosurgery dedicated to treating conditions of the blood vessels in the brain and spinal cord.

Endovascular surgery is a minimally invasive procedure that differs to traditional ‘open’ brain surgery in the following way.

  • Vascular (open) neurosurgery involves performing delicate microsurgical procedures through a craniotomy to directly access and repair abnormal blood vessels, such as clipping an aneurysm or removing an arteriovenous malformation.
  • Endovascular neurosurgery, by contrast, uses minimally invasive catheter-based techniques, where fine instruments are guided through the arteries to treat vascular problems from within, such as coiling aneurysms or placing stents.


Together, these two approaches provide comprehensive surgical options for managing complex cerebrovascular disorders.

Instead of opening the skull to perform surgery, endovascular neurosurgeons access the brain’s blood vessels through a small puncture in the groin or wrist, navigating catheters and micro-instruments through the vascular system under X-ray guidance.

Conditions treated:

Endovascular techniques are particularly useful in treating:

  • Brain aneurysms
  • Arteriovenous malformations (AVMs)
  • Dural fistulas
  • Carotid stenosis
  • Stroke


Endovascular techniques are particularly valuable in treating brain aneurysms, arteriovenous malformations (AVMs) and dural fistulas. For conditions like aneurysms, endovascular “coiling” has transformed outcomes worldwide, often replacing the need for more invasive open surgery.

Benefits of endovascular brain surgery include:

  • No need for large incisions or craniotomy
  • Faster recovery and shorter hospital stays
  • Reduced risk of infection and surgical complications
  • Ability to treat otherwise inaccessible lesions
  • Precision targeting of vascular abnormalities

Why Choose A/Prof Peter Mews?

Minimally invasive neurosurgery is not suitable for every patient or every condition, but when appropriate, it can make a profound difference to outcomes and recovery. These techniques combine the latest technology with meticulous surgical expertise – offering patients safer, more efficient treatment options.

A/Prof Mews is among a very small number of Australian neurosurgeons dual-trained in both endovascular and open cerebrovascular surgery. This rare expertise allows him to select the safest and most effective approach for each patient, placing him at the forefront of modern neurosurgical practice in Australia.
