We are dedicated to ensuring patients and families have their questions answered and their concerns addressed. Aneurysms and vascular diseases of the brain can be confronting, and it is natural to have a lot of questions. When you come to Sydney AVM, you will get the most up-to-date information about your condition, the risks you may face, the treatment options, and our assurance to support you into the future whether you choose to have treatment or watch and wait.

In some cases, treatments can have more risk than watching and waiting, and here at Sydney AVM we hold it as our ethical and moral responsibility to ensure that we do the best by you and your family. At Sydney AVM, you can be sure that we have your best interests in mind.

Initial consultations are 30 minutes long – this allows us to have a detailed assessment and discussion in a relaxed and comfortable setting. Consultations are comprehensive where I will take patients through their MRI or CT scans in detail in real time on the screen and explain clearly what their condition is, the risks they face from their condition, and how I would treat their condition. At the end of the consultation, patients and families will have a clear understanding of their condition and the proposed treatment approach.

We encourage our patients to have their family or close loved ones involved in the consultation process. This helps address all concerns, ensure that all questions are answered, and we can address questions on family screening (e.g. should my siblings or children get MRIs?).

At Sydney AVM we have a strong model of care where we undertake individual risk assessments for patients with aneurysms and AVMs. We compare the risks you face from your disease with the risks associated with different treatment options.

Our practice staff are integral to Sydney AVM and provide a great level of support and information for our patients regarding the administration and financial aspects of patient care.

Our team are trained to answer questions regarding informed financial consent, out of pocket costs and what you are entitled to receive back from your health fund for any given procedure, as well as questions about the hospital stay and admission processes. They liaise closely with all patients to ensure that the process from consultation booking, to hospital admission and follow up is streamlined.

We work closely with Dr Ngaroma Steele, an outstanding and caring anaesthetist who has extensive experience in neuro-anaesthesia and interventional neuroradiology procedures. Dr Steele has a great ability to help patients and families feel comfortable and relaxed about the anaesthesia process and she is a huge asset to our team. Dr Bhatia had the pleasure of first working with Roma as interns at St Vincent’s Hospital many years ago, and this long history allows us to communicate effectively about your care before, during, and after your procedure.

In our practice we use cutting-edge minimally invasive techniques, going through the blood vessels to reach the brain. For our procedures, we make an incision less than half a centimetre across to get access to the vessels of the thigh or wrist. Using these small access points, we use thin flexible plastic tubes (catheters) to reach the brain vessels. Once in position, we can treat the aneurysm or malformation using the latest devices including thin platinum coils, stents, and liquid agents that can occlude malformations in a slow and controlled ‘lava’ technique. We use angiography, where we can see the blood vessels by injecting dye into them whilst we take x-rays, to guide my procedures to ensure we are always in the right place. Dr Bhatia has also trained in the use of robots for endovascular treatments and was involved in the first robot-assisted brain aneurysm treatments in the world during his fellowship in Canada.

We are equally comfortable using the wrist artery and the thigh artery for access, and in 2019 Dr Bhatia designed and completed a world-first randomized controlled trial using the wrist artery for brain angiography. Where it is safe to do so, using the wrist artery allows you a quicker recovery, lower risk of bleeding, and allows you to sit up straight away after your procedure.

Dr Bhatia has extensively studied, published, and taught on the anatomy of the brain, face, and spine (neuroanatomy), including a PhD from the Department of Anatomy at University of Sydney. This advanced knowledge of anatomy allows him to target your treatment down to the finest detail.

After completing medical school at the University of Adelaide in 2006, Dr Bhatia moved to Sydney for internship and resident years at St Vincent’s Hospital. Following this he undertook two years of neurosurgical experience, a Master of Surgery at the University of Sydney, and then completed five years of radiology training at St Vincent’s Hospital (FRANZCR). During his radiology training he also undertook a PhD in advanced neuroimaging and neuroanatomy at the University of Sydney.

Following radiology training Dr Bhatia completed three years of additional fellowship training in interventional radiology (IR), interventional neuroradiology (INR), and paediatric INR. This included two years across Royal Prince Alfred and Royal North Shore Hospitals, following which his training and skills in INR were formally recognized by the Conjoint Committee for recognition of training in Interventional Neuroradiology (CCINR) in 2018.

For your own assurance, you can find Dr Bhatia’s name on the CCINR register: www.ccinr.org.au/register

In 2019, Dr Bhatia undertook an additional capstone fellowship experience at the prestigious Toronto Western Hospital and the Hospital for Sick Children in Toronto, Canada. In Toronto he was trained by world renowned leaders in the field of INR - Professor Timo Krings and Professor Vitor Mendes Pereira, both trained in Paris by a founding father of INR – Pierre Lasjaunias. During his time in Toronto, Dr Bhatia gained additional skills in the most advanced treatments in the field of INR including embolization of arterio-venous malformations (AVMs), complex dural arterio-venous fistulae (dAVFs), and the most modern techniques for the treatment of brain aneurysms using flow diverters, stent-assisted coiling, and robot-assistance. During this time Dr Bhatia also designed and ran a world first randomized trial using the wrist artery for brain angiography – a technique that is more comfortable for patients and allows them to sit up during recovery.

Whilst in Toronto, Dr Bhatia was also extensively trained in performing INR procedures for children at the world famous Hospital for Sick Children, including embolization of vein of Galen malformations, facial vascular malformations, intra-arterial chemotherapy for retinoblastoma, and treatment for the youngest child to ever undergo stenting for idiopathic intracranial hypertension. He was also involved in the first brain angiograms for children in Canada using the wrist artery.

At the St Vincent’s Health campus in Sydney, Dr Bhatia works across the public and private hospitals, providing diagnostic and interventional neuroradiology services of the highest standard. Through Sydney AVM, he provides the most thorough and modern clinical service for the assessment, family screening, and treatment of brain aneurysms, by using risk assessment scoring systems, modern vessel wall imaging techniques, and the latest in endovascular technology. He provides these same cutting-edge tools for the management of brain AVMs, dural fistulae, and vascular malformations of the head and neck.

Dr Bhatia currently undertakes the highly specialized Vein of Galen Malformation (VoGM) embolization procedures in infants at Children’s Hospital Westmead alongside his colleague Dr David Lord and provides INR services for the treatment of paediatric stroke and complex vascular malformations in children. He has published the most up to date article on outcomes and complications of VoGM embolization (from the Toronto cohort) in the prestigious JAMA Neurology and the largest systematic review of thrombectomy in paediatric stroke in Journal of Neurosurgery: Pediatrics.

Dr Bhatia has published over 20 peer-reviewed articles and book chapters, is a reviewer for Clinical Neuroradiology, Interventional Neuroradiology, and European Journal of Radiology, sits on the RANZCR Reference Group for IR/INR, and is a Clinical Senior Lecturer with University of Sydney, UNSW, and Macquarie University.

When you or your child has a condition affecting the blood vessels of the brain, you want to see someone who has been trained by the best, who uses the latest technology, and who gives you advice in a caring environment where your concerns are addressed. When you see Dr Bhatia, not only will you receive the benefits of 20 years of medical training, you can rest assured that he will manage and follow-up your condition well into the future and provide screening for your family members when it its appropriate.

With a PhD in neuroanatomy, Dr Bhatia has a highly detailed roadmap in his mind of every corner of the brain and its blood vessels – this is knowledge he will use to ensure your treatment is performed with millimetric precision. Dr Bhatia is the only INR practitioner in Australia with a PhD in neuroanatomy – so you know you will benefit from the highest level of knowledge when you come to Sydney Aneurysm.

Dr Bhatia is the only INR practitioner in NSW to have undertaken dedicated paediatric INR training in a world-leading paediatric hospital – the Hospital for Sick Children in Toronto. When its your child, you want someone who uses the most gentle techniques, understands the differences between child and adult vascular conditions, and knows how to discuss these complex conditions with children and their families. If Dr Bhatia undertakes a procedure for your child at the Children’s Hospital at Westmead, you will have the full benefit of the specialized medical, intensive care, nursing, and allied health staff at the largest children’s hospital in NSW. Unlike other INR services that only provide a ‘drop-in’ presence or admit children to adult wards, Dr Bhatia works regular days at the Children’s Hospital at Westmead because he believes that children deserve a doctor who they can rely on and who will address their needs and concerns.

Ethics & Certification

Interventional neuroradiology (INR) is a highly specialized branch of medicine where we use image-guidance (ultrasound, x-ray, angiography) to help us treat vascular diseases of the brain, face, neck, and spine. Most often, this involves guiding small tubes through the artery of the thigh or wrist to reach the brain vessels. INR practitioners have initially trained in radiology (reading imaging studies) and then trained in using imaging to perform complex treatments. Whilst a neurosurgeon can perform an open surgery for your brain by removing a flap of bone, INR can treat the same aneurysm or AVM from a very small nick in the skin over the thigh or wrist. Some neurosurgeons and neurologists also perform INR procedures, but a radiology trained INR practitioner has years of experience in reading imaging studies and using image guidance to perform procedures such that it has become second nature to them.

After completing at least 5 years of training in radiology, neurosurgery, or neurology, an INR practitioner must complete a minimum of two years further training in INR fellowships and meet a stringent set of criteria outlining the number of cases performed as primary operator under supervision. Once these stringent criteria are met, in Australia and New Zealand they are then recognized by the Conjoint Committee for recognition of training in Interventional Neuroradiology (CCINR).

Dr Bhatia was officially recognized on the CCINR register in 2018.


In addition, after being recognized by the CCINR, Dr Bhatia undertook a further year of highly specialized fellowship training in Toronto, Canada so he become fully skilled in the treatment of brain and spinal cord AVMs, dural fistulae, complex aneurysms, and paediatric INR procedures. Because of Australia’s smaller population and the historic tendency for neurosurgeons in Australia to perform open operations on brain AVMs, getting sufficient experience in these conditions was not feasible without going overseas – so Dr Bhatia went to a world leading centre to train in these procedures.

At Sydney AVM, we hold it as our ethical duty to make sure patients and their families have their questions and concerns addressed, that they have all the information they need before considering treatment, and that they are treated in a caring and comfortable environment. Our initial consultations are 30 minutes in length to ensure there is time to ask and answer questions, so patients and families feel comfortable and relaxed.

We encourage you to have your family and loved ones with you during the consultation to support you and ask questions. We also hold it as our ethical responsibility that patients are followed up in the long-term, using annual imaging to ensure their condition is under control and are treated to the highest standard.

For the treatment of children, Dr Bhatia maintains regular days at the Children’s Hospital at Westmead to ensure patients get consistent, high-level care in a dedicated children’s hospital by doctors specifically trained in paediatric procedures. He is the only INR practitioner in Australia to undertake regular planned sessions every week at a children’s hospital.

We believe that children and their families deserve better than a ‘drop-in’ service by an adult INR practitioner or treatment by practitioners who are not trained in the needs and complexities of babies and children. We also believe children and their families deserve care and recovery after their procedures in a hospital dedicated to children and we oppose the idea of transferring children to the unfamiliar environment of an adult hospital.

Ask your INR practitioner if they received dedicated training at an international children’s hospital before you place your child in their hands.
