What is brain aneurysm?

4 May 2021

It is a bulge in the brain blood vessels, which when bursting causes a subarachnoid hemorrhage, which is known as a hemorrhagic stroke, constituting a life-threatening medical emergency that must be treated immediately.

When there is no aneurysm rupture, often there are no symptoms or complications and they are usually detected by chance when performing studies for other conditions, establishing preventive treatment to avoid subsequent rupture.

There is no specific cause for the appearance of a brain aneurysm, but a series of potential risks have been identified for developing it, such as:

High blood pressure.
Family history.
Alcoholism.
Drug addiction.
Being of old age.
Being a woman.
Smoking.

Potential birth risks:

Hereditary conditions that weaken the vascular system.
Polycystic kidney disease.
Aortic narrowing.
Cerebral arteriovenous malformations.

Signs and symptoms Brain aneurysm

Ruptured aneurysm:

Intense and sudden migraine.
Droopy eyelids.
Fainting.
Mental disorder.
Nausea and vomiting.
Numb neck.
Blurred vision.
Photosensitivity.
Seizures.

Unruptured aneurysm:

Pupil dilation.
Eye pain in the upper inner part.
Visual problems.
Tingling or stiffness on one side of the face.

When a brain aneurysm ruptures, the hemorrhage damages cells and raises the pressure in the brain, which can cause fainting or be fatal.

Diagnosis and treatment Brain aneurysm

When experiencing the symptoms of a ruptured aneurysm, doctors in the Emergency Room will focus on the location of the injury and the identification of the cause through various studies such as:

MRI.
Brain angiography.
Computed tomography.
Lumbar puncture to obtain cerebrospinal fluid.

Once the aneurysm has been identified, the indicated surgical procedures are:

Surgical stapling to stop bleeding.
Endovascular embolization with a wire that seals the aneurysm through an arterial catheter.
Blood flow diverters.
