Vasospasm in Pediatric Subarachnoid Hemorrhage

Area of Science:

• Neurology
• Pediatric Critical Care
• Neurosurgery

Background:

• Cerebral vasospasm (CV) is a severe complication of subarachnoid hemorrhage (SAH).
• CV is less common in children than adults but can be devastating.
• Pathophysiology involves molecular and inflammatory phenomena, with protective factors like collateral circulation in children.

Purpose of the Study:

• To review current literature on cerebral vasospasm in children following subarachnoid hemorrhage.
• To outline the presentation, diagnosis, and management of pediatric CV.

Main Methods:

• Literature review of cerebral vasospasm in pediatric subarachnoid hemorrhage.
• Analysis of diagnostic imaging techniques.
• Review of current management strategies.

Main Results:

• Pediatric CV may be asymptomatic or present with altered neurologic status.
• Diagnosis confirmed by imaging showing >50% arterial caliber reduction.
• Management includes supportive care, calcium channel blockers, and neurointerventions.

Conclusions:

• Cerebral vasospasm in children post-SAH requires prompt diagnosis and management.
• While less common, pediatric CV necessitates specific consideration.
• Long-term outcomes for children experiencing CV are generally favorable.
