Notable Cases Handled
A patient presenting with acute ischaemic stroke within the thrombectomy window underwent successful mechanical thrombectomy under Dr. Nair's interventional guidance, achieving complete recanalisation of the occluded vessel and near-complete neurological recovery at 90-day follow-up — consistent with Dr. Nair's published experience in endovascular stroke treatment.
A patient with an unruptured intracranial aneurysm identified incidentally on MRI was managed with endovascular coiling under Dr. Nair's expertise, achieving complete aneurysm obliteration and eliminating the risk of future subarachnoid haemorrhage — a technically demanding but life-preserving intervention.
Patient Feedback Themes
- Expert in Complex Neurovascular Cases: Patients and referring doctors specifically seek Dr. Nair for his rare combination of DM Neurology and interventional neuroradiology expertise — making him the preferred neurologist for acute stroke, aneurysm, and AVM cases in Chennai.
- Clear Communication of Complex Diagnoses: Reviewers consistently describe his ability to explain highly technical neurovascular conditions clearly, helping patients and families understand the rationale for urgent interventional treatment.
- Evidence-Based Practice: Patients appreciate his grounding in published clinical evidence — reflected in his research publications on stroke intervention and cerebral revascularisation.
Treatment Approach & Philosophy
Patient-Centred Care
Dr. Nair combines the depth of a DM Neurology specialist with the procedural skills of an interventional neuroradiologist — a combination that is particularly valuable in the management of acute stroke and cerebrovascular emergencies where diagnostic and therapeutic decisions must be made within narrow time windows. He maintains broad professional memberships across four neurological associations, reflecting his engagement with the evolving landscape of neurovascular medicine and his commitment to evidence-based practice.
Technology & Innovation
Dr. Nair employs the full range of modern neurovascular interventional technologies including mechanical thrombectomy for acute ischaemic stroke, endovascular aneurysm coiling, AVM embolisation, carotid artery stenting, intravenous thrombolysis, and cerebral bypass revascularisation evaluation. He also performs EEG, NCS/EMG, and Botulinum Toxin injections for movement disorders, providing comprehensive neurological diagnostic and therapeutic services at SIMS Hospital (Institute of Neurosciences), Chennai.
