Severe aortic stenosis and subarachnoid hemorrhage: Anesthetic management of lethal combination

Area of Science:

• Neurology
• Cardiology
• Interventional Radiology

Background:

• Subarachnoid hemorrhage (SAH) is a critical neurological condition with high mortality rates.
• Comorbidities significantly worsen SAH outcomes, posing management challenges.
• Severe aortic stenosis (AS) is a critical comorbidity that complicates SAH management.

Observation:

• A patient with known severe aortic stenosis (AS) presented with aneurysmal subarachnoid hemorrhage (SAH).
• The patient was scheduled for neurovascular intervention, requiring careful consideration of AS-related risks.
• Management decisions were guided by the need to balance neurological intervention with cardiovascular stability.

Findings:

• Successful neurovascular intervention was performed despite the complexities introduced by severe AS.
• The patient experienced a favorable outcome, demonstrating the feasibility of managing complex SAH cases with comorbidities.
• Careful pre-procedural assessment and meticulous planning were crucial for achieving a positive result.

Implications:

• This case highlights the importance of multidisciplinary assessment in managing SAH patients with severe AS.
• It suggests that neurovascular interventions can be safely performed in select patients with severe AS and aneurysmal SAH.
• Effective management strategies can mitigate risks and improve outcomes for patients with combined critical conditions.
