Immediate Management of Aneurysm

Critical First Steps

The American Heart Association recommends immediate neurosurgical consultation and transfer to a comprehensive stroke center with neurosurgical expertise for patients with a diagnosed aneurysm presenting with concerning symptoms that may represent subarachnoid hemorrhage or impending rupture 1
Determine immediately whether this is an intracranial (cerebral) aneurysm or another type, as management differs dramatically 1, 2
Review the ER imaging reports to identify the exact aneurysm location and size 2
Review the ER imaging reports to identify whether there is evidence of subarachnoid hemorrhage (SAH) on CT 1
Review the ER imaging reports to identify whether the aneurysm is ruptured or unruptured 1, 2

Maintain systolic BP <160 mmHg to prevent rebleeding in patients with unsecured aneurysm 3, 4
Avoid hypotension with MAP ≥65 mmHg to prevent cerebral ischemia 4
Use short-acting, titratable IV agents like nicardipine (preferred) or clevidipine for blood pressure management 3, 4
Avoid rapid BP fluctuations >70 mmHg in 1 hour, which increase rebleeding risk 3

Start nimodipine 60 mg every 4 hours orally or via enteral tube immediately if patient presented within 96 hours and has adequate BP 2
Continue nimodipine for 14-21 days 2

Coordinate with receiving facility for continuous arterial line BP monitoring and frequent neurological examinations to detect deterioration 3
Maintain systolic BP <160 mmHg but avoid hypotension <110 mmHg during transfer 4
Maintain euvolemia with crystalloid infusions during transfer 4
Communicate directly with accepting neurosurgeon before transfer 1
Send all imaging with the patient 1
Ensure IV access and continuous monitoring during transport 3
Document baseline neurological examination 3
