[|Human|] Is it better to have a non-invasive surgery for a brain aneurysm or is it better to have the surgery that is more invasive going in through the skull. Do both surgeries have the same risk. My brother-in-law is being prepared to undergo the non-invasive surgery and I have been reading about both and was wondering which is less risky. His aneurysm is on the main artery and deep into his brain.
[|AI|]  I read your question and I understand your concern. Brain aneurysms are very delicate malformations whose choice of treatment depends on many factors like location, form, size, characteristics of blood flow etc. Every aneurysm has its own architectural characteristics and the decision is made individually based on those parameters, it is judged by specialized neurosurgeons in that area. It also depends in the center your brother-in-law is being treated and their experience and level expertise for different treatment techniques, not all surgeons and neurointerventionist are the same when it comes to such specialized procedures. Generally speaking, both techniques have their advocates, perhaps noninvasive techniques are less risky in the short run, but surgical ones offer more long term assurance. But as I said it's an individual decision for each patient and aneurysm, to be taken by your doctors based on brain imaging info. I hope things work out for the best.
