Hello, Amy...and welcome, it is great you can ask questions...we can only suggest what to ask your neurospecialist... and/or for a second opinion...you may elect to do both...Get your med records to better understand the terminology of the artery / lobe, etc...to help your research and questions to ask the neuro.
1. No way to predict...likely vary in time depending on the aneurysm location, our overall health and of our arteries; if any accident bouncing the inside of our head; i.e. MVA, fall, etc. that may initiate/generate growth.
2. I believe symptoms are related and start even earlier which are not addressed/considered to be unusual... when the lighter headaches/pressure begins...and, mini-memory lapses...which I call blank-outs vs black-out and, more..
3. What did your md suggest you watch for? My personal opinion is that it varies, too; i.e. location of the aneurysm, and potential rupture location, volume of a leak...Ask your neuro if the angio images display the most weakend area that may likely become the leak/rupture site. Because I had ruptured, there was no question about its location in my natural aneurysm.
4. Do you mean the symptoms, i.e. headache, etc...after treatment; or if the aneurysm may diminish on its own... The daughter of friends was in a diff hospital than me, was diagnosed w/aneurysm...hers did disappear before treatment. She was told to reduce her exercise and a few more things...When we have our NY greetings, I will ask status and if she has had follow-up to assure no re-growth/development.
After treatment, many of us have continued symptoms, some decline, are intermittent, and some can expand for various reasons by location, its size, the quality of treatment...
It is more than delightful to read from others when they share their remarkable results.
5. If I remember correctly, stats show apx 20% of us have more than one. I know of one local peer who had three all diagosed w/the diagnosis of the one that had ruptured.
6. If/when you are not comfortable w/answers from your current provider...get a second opinion.
Do secure your records for the terminology to help you research, share w/us, and, definitely to ask your neuro questions. You can also secure a CD of your angiogram. Do ask your neuro of hisexperience, i.e. average annual treatment; how many years of experience, and whatever else comes to mind...
The BAF has (if I remember correctly), a draft image of the circle of Willis which is the connector source of our cerebral arteries... Once you have the name of the artery, it can be fairly reasonable to research.
Also look at the groups in the BAF site to see if one is near you for local input as well.
You are blessed to have a supportive hubby and an early diagnosis...
Please keep us informed...plan a wonderful, happy New Year for your best decisions.
