Best Neurosurgeons for Brain Aneurysms in Chennai, India

A brain aneurysm is an abnormal balloon-like bulge that forms in the wall of a blood vessel in or around the brain, arising where the vessel wall has become weakened. If the aneurysm ruptures, it releases blood into the space surrounding the brain, a medical emergency requiring immediate attention.

Unruptured aneurysms are often completely silent, though larger ones may press on nearby structures and cause headaches, vision changes, drooping eyelid, or facial pain. A ruptured aneurysm typically causes a sudden, severe 'thunderclap' headache — often described as the worst headache of one's life — sometimes accompanied by nausea, stiff neck, sensitivity to light, or loss of consciousness. Experiencing any of these symptoms does not confirm the presence or rupture of an aneurysm, and a formal clinical assessment with appropriate imaging is required to establish what is happening.

Diagnosis typically begins with a detailed medical and family history, followed by neurological examination and brain imaging — most commonly CT angiography (CTA) or magnetic resonance angiography (MRA) for initial detection. If a rupture is suspected, a CT scan of the brain is usually the first step, with lumbar puncture considered if the scan result is inconclusive. For treatment planning, conventional digital subtraction angiography (DSA) is often performed to provide precise detail about the aneurysm's size, neck geometry, and relationship to surrounding vessels; aneurysms may also be informally graded by size (small: under 7 mm, medium: 7–12 mm, large: 13–24 mm, giant: 25 mm or more) and by the Hunt and Hess or World Federation of Neurosurgical Societies (WFNS) scale when a rupture has occurred.

Management is highly individualised and depends on factors including the aneurysm's size and morphology, its location, whether it has ruptured, the patient's age, overall health, and the findings of detailed imaging. For unruptured aneurysms deemed low-risk, active surveillance with periodic imaging may be the recommended approach rather than immediate intervention. When treatment is indicated, the two principal procedural options available in our directory are microsurgical clipping — in which a neurosurgeon places a small metal clip across the aneurysm's neck via open craniotomy — and endovascular coiling, in which a neurointerventional specialist threads platinum coils through a catheter to pack the aneurysm from within; the choice between them depends on individual anatomy and a multidisciplinary team assessment.

For aneurysms that are small, unruptured, and carry a low estimated rupture risk, a conservative approach of regular imaging surveillance combined with aggressive management of modifiable risk factors — controlling blood pressure, stopping smoking, and avoiding stimulants — can be a clinically appropriate strategy. This pathway requires close, ongoing follow-up and is only suitable for carefully selected patients as determined by a specialist; it is not a substitute for treatment when intervention is recommended. There is no meaningful medication that shrinks or seals an aneurysm, so non-surgical management focuses entirely on risk reduction and monitoring.

Brain Aneurysm Clipping may be considered when conservative or medical options have not achieved enough improvement, or when the severity of the condition warrants it. The decision depends on clinical assessment, expected benefits and individual risks.

Brain aneurysms are typically evaluated and managed by a cerebrovascular neurosurgeon (for microsurgical treatment) and/or an interventional neuroradiologist or endovascular neurosurgeon (for catheter-based coiling and flow-diversion procedures). In centres with the appropriate infrastructure, these specialists work within a multidisciplinary cerebrovascular team that may also include neurointensivists and rehabilitation specialists.

When selecting a provider for a brain aneurysm, it is worth comparing the surgeon's or neurointerventionalist's documented case volume and experience with aneurysms of a similar size and location to yours, as well as the hospital's access to both microsurgical and endovascular capabilities, neurointensive care, and structured long-term follow-up imaging protocols.
