Neurovascular Conditions and Diseases Treated
Understanding Neurovascular Conditions
Neurovascular conditions affect the delicate blood vessels of the brain and spinal cord. They can disrupt blood flow, weaken vessel walls, or create abnormal connections, placing patients at risk of serious complications such as ischaemia or haemorrhage.
Because these conditions are often complex and potentially life-threatening, accurate diagnosis and timely treatment are essential. Mr Kailaya-Vasan is a consultant neurosurgeon with specialist expertise in neurovascular surgery. He offers advanced care for patients with rare and high-risk vascular disorders.
If you don’t see your specific diagnosis here, please reach out to Mr Kailaya-Vasan’s team directly. He frequently treats rare and complex cases, and his expertise may still apply to your situation.
Specialist Neurovascular Services
-
Arteriovenous Malformations
AVMs are abnormal tangles of arteries and veins in the brain or spine. They may cause headaches, seizures, or bleeding. Treatment options include embolisation, radiosurgery, or microsurgery depending on size and location.
-
Brain Aneurysms
A brain aneurysm is a bulge in a weakened artery wall. While many are silent, a rupture can cause life-threatening bleeding. Early diagnosis and treatment, such as clipping or coiling, can prevent complications.
-
Cavernomas
Cavernomas are clusters of fragile blood vessels that can leak limited amounts of blood. Symptoms may include seizures or neurological changes. Some require only monitoring, while others may be removed surgically.
-
Dural Arteriovenous Fistulae
A dAVF is an abnormal link between arteries and veins in the dura (the brain’s outer covering). They can cause headaches, tinnitus, or neurological symptoms. Endovascular embolisation or surgery may be recommended
-
Headaches
Headaches are one of the most common neurological symptoms, ranging from mild tension pain to severe, persistent pain linked to vascular or structural causes. Diagnosis and treatment focus on identifying the underlying trigger through specialist assessment and imaging.
-
Intracerebral Haematoma
An intracerebral haematoma is bleeding inside the brain, often due to high blood pressure, trauma, or a vascular abnormality affecting parts of the brain. It can cause sudden neurological symptoms and may require emergency surgery.
-
Intracranial Vascular Disease
This includes narrowing or blockages in the brain’s arteries, which increases the risk of stroke or transient ischaemic attacks (TIAs). Treatment may involve medication, lifestyle changes, or surgical bypass in selected cases.
-
Moyamoya
Moyamoya disease is a rare cerebrovascular disorder caused by narrowing of the internal carotid arteries, which reduces blood flow to the brain. It can lead to recurrent strokes, transient ischaemic attacks (TIAs), or headaches, and is sometimes treated with surgical bypass to restore circulation.
-
Subarachnoid Haemorrhage
A subarachnoid haemorrhage is bleeding around the brain, usually from a ruptured aneurysm. Symptoms include a sudden severe headache, nausea, or collapse. Urgent treatment is vital to secure the aneurysm and prevent re-bleeding.
Why Specialist Care Matters
Neurovascular conditions require highly specialised expertise. Early recognition, accurate diagnosis, and tailored treatment significantly improve outcomes.
Mr Kailaya-Vasan is widely recognised for his skill in managing complex neurological conditions, offering patients domestically and internationally access to advanced techniques within leading private hospitals in London and the Southeast.
If you or a loved one has been diagnosed with a neurovascular condition, early specialist review can make a vital difference
