So, in a year, they do another CT angiogram to determine if it's growing. And if it is, they want to consider doing a minimally invasive surgery called Coil Embolization, in which they will snake a catheter into my leg and into my blood vessels and then, through that, insert a small coil into the aneurysm. Blood clots will form around the coil, preventing blood from flowing into the aneurysm and therefore releasing the pressure on it.
I'm hoping the aneurysm just stays nice and small. I don't want to have something foreign snaked into my brain through my leg. That sounds horrible. And apparently something like 7% of the procedures require additional surgery or treatment. Not great.
But it could be worse, so I'm pretty happy about the news.
