Consultant Interventional Neuroradiologist (INR) – Atkinson Morley Neurosciences Centre at St George’s Hospital in London.

Clinical interests

Dr Madigan specialises in the diagnosis and treatment of blood vessel disorders of the brain and spine. This includes aneurysms, arteriovenous malformations (AVM), dural arteriovenous fistulae (dAVF), vasospasm following subarachnoid haemorrhage and acute ischaemic stroke (mechanical thrombectomy).

He has experience in all aspects of adult diagnostic and interventional neuroradiology, but specific diagnostic interests include neurovascular disease and dementia.

Professional profile

Dr Madigan undertook his undergraduate training at the University of Otago, New Zealand. He attained a BSc in Chemistry in 1996 before training in medicine and qualifying with an MBChB in 2001. He moved to London in 2003 where he trained in clinical radiology at St George’s Hospital, gaining Fellowship of the Royal College of Radiologists in 2007. Between 2008 and 2010 he undertook a fellowship in diagnostic neuroradiology and neurointervention at the National Hospital for Neurology and Neurosurgery, Queen Square. In 2010 he was appointed as a Consultant diagnostic and interventional neuroradiologist (INR) at the Atkinson Morley Neurosciences Centre at St George’s Hospital.. He is also an Honorary Senior Lecturer at St George’s University of London Medical School, working in the Stroke and Dementia Research Centre.

What is Interventional Neuroadiology?

Interventional neuroradiologists work closely with vascular neurosurgeons, neurologists and stroke physicians to help diagnose and treat blood vessel problems in the brain, neck and spine. INRs now delivery the treatments for many of the conditions previously treated by open brain surgery, using non-invasive keyhole techniques and advanced imaging. When open surgery is required, we help the neurosurgical team with identification and visualisation of the blood vessel problem in question. This multi-disciplinary team based approach, combining different skill sets from each specialty, leads to better outcomes for patients.
