Main Disorders

  • Brain Aneurysm

  • AVM

  • Ischemic Stroke (Brain Attack)

  • Carotid Artery Disease

  • DAVF

Two images for Brain Aneurysm

Brain Aneurysm

A brain aneurysm is a bulge or ballooning in the blood vessel of the brain which may leak or rupture, causing bleeding into the brain which is called subarachnoid hemorrhage.

The brain aneurysms result from a combination of hemodynamic stresses and acquired degenerative changes within the arterial wall. There are some predisposing factors for aneurysms like Adult polycystic kidney disease or marfan’s syndrome.

Brain arterio-venous malformation (avm)

Brain Arterio-Venous Malformation (AVM)

An AVM is a tangle of abnormal and poorly formed blood vessels in the brain connecting arteries and veins directly. AVMs can occur anywhere in the body but are most common in the brain and spine. Brain AVMs, which although rare, are of special concern because of the damage they can cause if they rupture.

Ischemic Stroke

Ischemic Stroke (Brain Attack)

A stroke occurs when blood supply to a part of the brain is reduced or completely stopped. Ischaemic stroke is the most common type of stroke and it caused by narrowing or blockage of blood vessels by fatty deposits, blood clots or other debris.

Carotid Artery Disease

Carotid Artery Disease

Carotid artery disease occurs when fatty deposits deposit on the wall of the arteries leading to narrowing of the carotid arteries that supply blood to the brain leading to increased chances of stroke. This usually develops slowly and the first sign may be a transient ischaemic attack in which the blood supply to the brain is temporarily disrupted.

Dural arteriovenous fistula (DAVF) and Transverse Sinus

Dural Arteriovenous Fistula (DAVF)

They are abnormal connections between an artery and a vein in the dura mater, which is the tough covering over the brain and spinal cord. They tend to occur later in life and most of them occur due to blockage or narrowing of the brain’s venous sinuses which drain the circulated blood back from the brain to the heart.

What is Interventional Neuroradiology?

Interventional neuroradiology is a subspecialty of interventional radiology which involves using medical imaging tests in diagnosing and treating diseases of the central nervous system, head, neck and spine.

Interventional neuroradiologists use cutting edge imaging and guidance techniques to guide catheters (very fine plastic tubes) and other tiny instruments around the arteries and veins in the head, neck or spine to treat conditions such as strokes or aneurysms.
