What are the available treatment options for brain aneurysms at Queen Square?

So conventionally aneurysms are treated with a surgical clipping procedure. It's quite an invasive procedure. It's fairly well-established, and it's traditionally been the way of treating aneurysms. More recently, since a very large published international study, the ISAT study, there's good evidence to show that endovascular treatment of aneurysms, particularly in the acute setting, is, on the whole, more favourable. It's very well-tolerated by the majority of patients, and the technology's moved on. So there's other adjunctive devices one can use to treat endovascularly aneurysms as well.
