General facts about Brain Aneurysm survival rate

Aneurism of the brain is a swelling or a little balloon being created on a blood vessel inside the brain which often reminds of a grape fruit. It can leak or expand further, causing bleeding inside the brain. Commonly, brain aneurisms are happening in the space between brain and the thin tissue which is covering it. This type of brain stroke is called subarachnoid hemorrhage. Rupture of the aneurism can quickly become fatal and it needs instant medical assistance.

Still, most of brain aneurysm never ruptures which means that these don’t cause any health issues and aren’t traced with symptoms. Such aneurysms are usually diagnosed during testing for some other diseases. Treatment of the aneurysm while it is still intact can help in some cases, preventing the rupture in the future.


A sudden, strong headache is the key symptom of a ruptured aneurysm. This headache is usually described as the worst possible headache you can experience. Vomiting and loss of conscience are also common symptoms of a ruptured aneurysm.

In a case where the aneurysm is leaking, they can also excrete small amounts of blood. This kind of leak will probably cause only sudden and strong headaches. More severe rupture happens always after leaking of the aneurysm.

Solid aneurysm causes no symptoms whatsoever, especially if it’s small in diameter. However, a large solid aneurysm may apply pressure on the surrounding brain tissue and nerves which can cause pain above and behind the eye, expanded iris, and relaxed eyelids.

When should you visit your doctor?

A ruptured aneurysm requires emergency medical assistance. About 30% of ruptured aneurysm cases have fatal consequences. It’s important to ask for medical assistance in a case where you experience strong and long lasting headaches. If you are living with someone who is complaining about sudden strong headaches, call medical assistance as soon as possible as you may just save one life.

Causes of brain aneurysm

Brain aneurysms are developed as a result of thinning and degeneration of the arteries. Aneurysms are commonly formed when arteries spread apart since these parts of the arteries are considered to be the weakest. Despite the fact that aneurysms can occur anywhere in the brain, these are most commonly found on arteries entering the brain.

Treatment of brain aneurysm

In order to improve the brain aneurysm survival rate, proper treatment methods have been developed. You can solve the aneurysm surgically or with other types of treatment such as medicaments. Surgery is an effective but very risky method of brain aneurysm treatment. Embolization is less invasive of a procedure and it can be much more reliable in the beginning, but it also carries increased risks of future bleeding, so additional procedures might need to be taken. Your neurosurgeon will have recommendations for you based on the size of the aneurysm, your overall health state and some other important factors.

Generally, there is a high rate of brain aneurysm survival, but it’s important to get it discovered as early as possible since this vastly improves your chances for survival.
