The survival rate for a brain aneurysm depends on various factors, including the size and location of the aneurysm, the individual’s overall health, age, and the promptness of medical intervention. A brain aneurysm is a weakened, bulging area in the wall of an artery in the brain. If it ruptures, it can lead to a potentially life-threatening condition called subarachnoid hemorrhage (SAH), which is bleeding into the space around the brain.

1. Ruptured Aneurysms: The survival rate for a ruptured brain aneurysm can be lower, especially if not treated promptly. About 10% to 15% of people with a ruptured aneurysm die before reaching the hospital, and up to 40% may not survive the first 24 hours after the rupture. However, with quick medical intervention, the chances of survival increase.
2. Unruptured Aneurysms: The survival rate for unruptured brain aneurysms is higher, as long as the aneurysm is detected and managed in time. Many people with unruptured aneurysms can live their lives without experiencing any symptoms or complications.

Advancements in medical imaging, surgical techniques, and endovascular procedures have significantly improved the management and outcomes of brain aneurysms. For example, coiling (endovascular embolization) and clipping are common procedures used to treat aneurysms and prevent rupture.

It’s important to consult with a medical professional to get the most up-to-date and accurate information about survival rates for brain aneurysms, as well as the available treatment options. If you or someone you know is concerned about a brain aneurysm, seeking medical attention promptly is crucial.
