London Neurosurgery Partnership

Keyoumars underwent dual postgraduate training in surgery and medicine, obtaining Membership of the Royal College of Physicians (MRCP) in 1997 and the Fellowships of the Royal College of Surgeons of England and Glasgow (FRCS) in 1998. Thereafter, he underwent higher specialist training in general neurosurgery in London being awarded the Fellowship of the Royal College of Surgeons in Neurosurgery (FRCS SN) in 2002. His sub-specialist training in stereotactic and functional neurosurgery included a fellowship in France with Prof. Benabid, generaly considered as the founder of the modern deep brain stimulation surgery, which led to a MD degree. He was appointed as a consultant neurosurgeon at King’s College Hospital in January 2007. He is also a Reader at King’s College London.

In addition to his expertise in degenerative spine disease, which includes the management of back and neck pain, arm pain and sciatica together with peripheral nerve disorders such as carpal tunnel syndrome, Mr Ashkan’s main interests are neuromodulation surgery and brain tumours. This includes deep brain stimulation, spinal cord stimulation and occipital nerve stimulation for movement disorders, pain and headaches and image guided, minimally invasive and stereotactic surgery for brain tumours including awake craniotomies, Gamma and Cyberknife radiosurgery.

Mr Tolias has been a consultant Neurosurgeon at King’s College Hospital since September 2005.

He has a PhD in Biological Sciences from the University of Warwick and extensive research experience in traumatic brain injury.

Mr Tolias has vast Neurovascular experience and currently has the largest series of aneurysm surgeries in the UK (NNAP 2017).

He specialises in surgery of cerebral aneurysms, arteriovenous malformations, cavernomas and dural fistulas and rare conditions like Moya Moya.

He is one of the few surgeons in the UK who routinely performs cerebral vascular bypasses. He also performed the first ELANA bypass in the UK.

Mr Tolias has pioneered the use of bypass techniques in the management of cerebral vasculopathies.

He is trained in Gamma Knife and Cyberknife and routinely utilises innovative neuromonitoring technologies in the surgery of complex vascular lesions like arteriovenous malformations.

He is one of the few Neurosurgeons nationally who regularly undertakes surgical extirpation of arteriovenous malformations when indicated.

His outcomes are part of national databases and remain among the best in his peer group (NNAP 2017).

Alongside his subspecialty interest Mr Tolias has an active spinal practice dealing with problems of the cervical and lumbar spine. These can include sciatica, brachalgia, radiculopathies and pain management through both injections and radiofrequency ablation as well as surgical interventions.

Mr Tolias is the director of the first and only Royal College of Surgeons of England accredited National Neurovascular Surgical Fellowship based at King’s College Hospital.

He has over 60 papers in peer reviewed journals and more than 150 presentations at conferences. He regularly lectures in the UK and worldwide on topics including complex arteriovenous malformations, aneurysms, Gamma Knife and Cyberknife as well as degenerative spine conditions.
