For patients that we see in clinic with cerebral aneurysms, we have to have a long discussion to determine whether or not it requires any treatment at all. Depending on multiple factors such as how large the aneurysm is, where in the brain the aneurysm is located, it's not that uncommon that I'll see a patient in their 80's with a new diagnosis of an aneurysm, and those individuals the lifetime risk is exceedingly small. It isn't the best decision to go ahead, and pursue treatment for that. This is a team decision and relies on the patient, and myself coming up with the best strategy going forward. We do need to consider all sorts of factors like what impact on their lifestyle is, what their concerns about needing additional treatments in the future. Once they've had that aneurysm treated, oftentimes they'll talk about a giant weight being lifted off their shoulder or now they can look at the future in a much better light.
