A cerebral aneurysm is known by many names like brain aneurysm and intracranial aneurysm. Aneurysm in the brain is defined as dilations (widening) that occur at weak sites in the walls of the blood vessels of the brain.
A cerebral aneurysm is known by many names such as brain aneurysm and intracranial aneurysm. Aneurysm in the brain is defined as dilations (widening) that occur at weak sites in the arterial circulation or say, walls of the blood vessels of the brain. It is often identified as ballooning or bulging of the blood vessels.
The majority of brain aneurysms are silent and are only diagnosed by chance during neuroimaging or autopsy.
The condition often leads to expansion, thinning and rupturing of the blood vessels, known as subarachnoid haemorrhage. The haemorrhage results in haemorrhagic stroke or bleeding inside the brain, which is associated with a high risk of morbidity and mortality.
According to the recent news reports, the Chinese President Xi Jinping has a 'cerebral aneurysm' and was hospitalised in 2021 due to his declining condition.
Here's all about a cerebral aneurysm in detail. Take a look.
There are three types of cerebral aneurysm:
1. Saccular aneurysm: It is one of the common forms of cerebral aneurysm and is characterised as a round sac filled with blood and attached to the main artery.
2. Fusiform aneurysm: It is characterised as a ballon or a bulge from all sides of the artery.
3. Mycotic aneurysm: It resembles a fleshy fungus as it occurs mainly as a result of infection.
When the walls of the arteries in the brain become thin and fragile, cerebral aneurysms occur. The weakening may occur at any age and due to multiple factors. Some of the factors that may lead to the development of the condition are:
Some of the symptoms of a cerebral aneurysm (unruptured) may include:
Symptoms due to rupture of the aneurysm may include:
Not all brain aneurysms result in haemorrhagic stroke. Some of the factors that may lead to rupture of the aneurysm are:
Some of the complications of a cerebral aneurysm may include:
In most cases, unruptured brain aneurysms are diagnosed incidentally during neuroimaging. Some of these methods are:
Some of the treatment methods for cerebral aneurysms may include:
A cerebral aneurysm is a life-threatening condition; around 25 per cent of people who has a ruptured brain aneurysm do not survive the first 24 hours, and another 25 per cent dies from complications within six months. Subarachnoid haemorrhage can cause lasting neurological damage in certain people. This makes early diagnosis and treatment of a brain aneurysm important to improve the chances of a full recovery.
