Professor Diederik Bulters

Mr Bulters is a neurosurgeon with a sub-specialty interest in vascular neurosurgery.

 Training and education

  • MBChB and intercalated BSc in pharmacology, concentrating on neurophysiology, University of Edinburgh

  • Basic surgical training, University of Edinburgh

  • Specialist neurosurgical training, Wessex

  • Fellowship in neurovascular surgery, Cambridge


Mr Bulters is a consultant neurosurgeon specialising in neurovascular neurosurgery (treating conditions of the blood vessels in the brain and spine).

After completing his fellowship in Cambridge, he worked as a consultant neurosurgeon at Addenbrooke’s Hospital before moving back to Southampton. He has extensive experience in complex surgery for:

  • aneurysms (swelling in a blood vessel caused by weakness in the blood vessel wall)
  • arteriovenous malformations (groups of blood vessels that form abnormally)
  • dural arteriovenous fistulas (abnormal connections between an artery and a vein in part of the brain and spine called the dura mater).

Mr Bulters also provides all services for cerebral bypass (an operation to reroute blood around a damaged artery, preventing a stroke) in the south.

Key achievements

  • President of the British Neurovascular Group
  • Member of the Society of British Neurological Surgeons, European Association of Neurosurgical Societies and the Congress of Neurological Surgeons
  • Teaches and lectures on a wide range of courses nationally and internationally
  • Society of British Neurological Surgeons Research Committee member and associate editor of the British Journal of Neurosurgery


Mr Bulters has an active research interest in vascular neurosurgery. Hs group’s two main themes relate improving risk prediction and treatment for patients with vascular lesions (cerebral aneurysms, arteriovenous malformations and dural AV fistulae), and reducing the injury to the brain from blood to improve outcomes from intracranial and subarachnoid haemorrhage.

He holds grants from the NIHR, EPSRC, Innovate UK, MRC, European Union, Royal College of Surgeons of Edinburgh, Wessex Medical Research and Smile for Wessex and has been the chief and principal investigator for a large portfolio of randomised trials examining new ways to improve outcomes for patients with aneurysms and intracranial haemorrhage, utilising new drug interventions, cell therapies and surgical techniques.

He is Professor of Neurosurgery at the University of Southampton, collaborating with groups in the translation of laboratory studies into clinical intervention. This work is focussed on the biochemical effects of haemorrhage on the brain, and how these may be manipulated and ameliorated. This has led to a number of exciting putative interventions undergoing human clinical trials.
