Hey, sounds like me... 7 mm unruptured aneurysm a year ago. Please be calm and trust the process. I will say that is the most important thing. I was as terrified as you. I read tons and consulted 3 other neurosurgeons before the procedure. Angiogram process is safe and relatively fast. Mine came out ok, but I required a stent due to the size of the aneurysm, which was done later. Everything resulted ok, I am now due for an MRI, this week. The fear is there again, but I must remain calm because anxiety affected me markedly, sadly resulting in other health issues. You will be fine, your aneurysms are small and this is just a diagnostic test. God bless.
