Hello and thanks for using HCM.
I have read your question and understand your concerns.
A ruptured
brain aneurysm should be treated by surgery ( clipping) or by endovascular embolisation (coiling), because re-bleeding could be catastrophic.
If the aneurysm is closed by these measures there is no risk of re-bleeding.
Since there was infection (
Pseudomonas right?), first there is need to treat it by using antibiotics according to antibogram culture results.
If your mother is allergic to penicillin, she could not use it or other penicillin related antibiotics.
The treatment of the aneurysm should be done after the infection is treated successfully and confirmed by blood tests.
Till then, control of blood pressure between normal ranges is necessary to avoid re-bleeding.
Hope you found the answer helpful.
Greetings.
