Neurovascular Surgery at Macquarie Neurosurgery in Sydney

Expertise in rare and intricate neurological procedures

The  neurovascular surgical team at Macquarie Neurosurgery is internationally renowned for the treatment of brain aneurysms, brain and spine vascular malformations and disorders of the brain that require bypass surgery. 

The surgeons manage a high volume of patients and perform more than 200 neurovascular surgical procedures annually.

With specific expertise in rare neurovascular conditions, the neurosurgeons operate within state-of-the-art facilities using cutting-edge surgical equipment.

Patients who are cared for by Macquarie Neurosurgery’s medical team receive a comprehensive, multi-disciplinary care approach - as well as ongoing treatment and support following their surgery.  

The neurovascular surgical team are committed to the mission of demonstrable excellence, being at the forefront of knowledge and educating the next generation of neurovascular surgeons.

Neurovascular surgical procedures

Neurovascular surgery is intricate surgery. It can take many hours, depending on the type of procedure required. 

The accomplished neurovascular surgeons at Macquarie Neurosurgery treat a range of neurological conditions, including:

  • Aneurysms of the brain

  • Vascular malformations of the brain and spine

  • Vascular stenosis or blockage

  • Stroke prevention surgery or bypass surgery

All neurovascular surgical procedures are performed using miniaturised instruments and a microscope. This is known as microsurgery.

While the surgeons apply similar skillsets to each procedure, the approach and decision-making about every single case is personalised. This is just one of the ways the team works together to ensure the best possible patient outcomes.

Personalised decision-making

When it comes to making decisions about your surgery, your team of neurosurgeons and health professionals will consider your case as a whole. 

This includes assessing your scans and X-rays in great detail, and identifying the pros and cons of treating your condition with a surgical procedure or intervention (as not every aneurism needs to be treated, for example). 

The neurovascular surgeons at Macquarie Neurosurgery will work with you to determine the best course of action for your unique circumstances.


Multi-disciplinary team approach

If your condition does need an intervention, your surgical team will collaborate with other relevant medical specialists and allied health professionals to determine the best course of action for you.

Your case will be discussed in great detail and your team will recommend the optimal modality for your treatment - which can include surgery, Gamma Knife treatment or endovascular treatment.

Patient-centred consultations

If you require any type of neurosurgery, it’s important that your surgeon thoroughly explains your condition, discusses the potential treatment options and reviews any questions you may have. 

The surgeons at Macquarie Neurosurgery have an excellent reputation for this. They know how serious and anxiety-provoking neurosurgery can be for you - and they understand that putting your life and brain function in the hands of somebody you have only recently met is daunting. They will dedicate as much time as possible to addressing your concerns. 

Skilled in subspecialty surgery

Certain surgical procedures that Macquarie Neurosurgery’s medical team perform aren’t available in other departments around the country. 

Patients from interstate and overseas often visit the practice because the surgeons are able to treat rare and complex neurological conditions.

State-of-the-art tools

The neurosurgeons at Macquarie Neurosurgery operate using the most up-to-date tools in the country. They also have access to certain pieces of equipment that many other hospitals don’t have, including:

  • ICG angiography - ICG is used to acquire an angiogram of the choroid. The choroid is the layer of blood vessels and connective tissue between the sclera (white of the eye) and retina which supplies nutrients to the inner parts of the eye. ICG angiography allows surgeons to perform an angiogram during surgery, check on the progress of the surgery and then make ‘real-time’ decisions - as opposed to taking an angiogram back to the theatre and re-operating on the patient if necessary. 

  • Australia’s first Gamma Knife - Macquarie Neurosurgery utilise the first Gamma Knife machine in Australia. Gamma Knife is considered the best radiation technique to treat AVMs (arteriovenous malformations) when surgery is not indicated.


Expertise in treating intracranial aneurysms 

Members of the Macquarie Neurosurgery team have treated more than 6,000 aneurysms by surgery. Treatment is available by microsurgery (including clipping and bypass) and endovascular treatment (blocking the aneurysms by coils or stents delivered from a tube inserted in the artery).

As there is great variation of complexities in aneurysms and surgical best practices, our multidisciplinary team approach ensures that the treatment recommended is personalised.  

If an aneurysm is discovered after it has burst, leading to a bleed in or around the brain (subarachnoid haemorrhage), our well-developed protocols and integrated team approach ensures quick care for seriously ill patients.

If surgery or endovascular treatment is not necessary, our surgeons will monitor aneurysm growth and provide recommendations on modifying risk factors to avoid rupture.

Expertise in treating Arteriovenous Malformations (AVM) of the brain 

AVM of the brain, or tangle of fragile arteries and veins resembling a small ball of string, is responsible for bleeding into the brain. Approximately 200 Australians are diagnosed with this condition each year.

The Macquarie Neurosurgery team has treated more brain AVMs than any other Australian group. 

With three modes of treatment available, including microsurgery, radiosurgery (by Gamma Knife) and embolisation (blocking the vessels of the AVM by glue delivered from a tube inserted in the artery), the options for treatment are as comprehensive as anywhere in the world.  

Our experts contribute significantly to the current debate amongst the world’s leading neurosurgeons on the best way to manage brain AVMs. We also partake in research that looks to future new ways of preventing brain AVMs from bleeding.

Expertise in bypass surgery 

Brain bypass surgery is sometimes necessary to treat conditions that reduce the blood flow to the brain (eg  Moyamoya – see below).

It may also be necessary if blood vessels need to be replaced in the management of aneurysms or tumours of the skull base.  Because of the varied indications for bypass surgery, there are different types of bypass that might need to be performed. These bypass types are divided into high flow bypass techniques and augmentation bypass techniques.

Bypass surgery is rarely needed and performed. However, our experts have performed over 400 bypass surgeries and have published their results in leading journals.

Expertise in treating Moyamoya disease

Moyamoya - which means ‘puff of smoke’ in Japanese - is a rare, progressive disease characterised by blocked arteries at the base of the brain.

In patients who have this condition, bypass surgery is generally indicated in order to provide additional blood flow to the brain.

Macquarie Neurosurgery’s neurosurgical team have a high level of skill and experience in the treatment of children and adults with Moyamoya disease. Members of the surgical team have trained at Stanford, which is considered the world’s foremost authority on this uncommon disease. The surgeons have looked after more than 50 patients with Moyamoya disease, making them some of the country’s leading specialists trained in this condition.

Constant learning

Neurosurgeons at Macquarie Neurosurgery focus not only on excellent clinical care but also on educating future neurosurgeons. 

They regularly participate in neurosurgical research and are committed to transferring the leading procedures and innovations to all patients. 

Macquarie Neurosurgery’s alliance with Macquarie University & Macquarie University Hospital allows for the advancement of all areas of neurosurgery.
