Reversible Cerebral Vasoconstriction Syndrome: Recognition and Treatment

Area of Science:

• Neurology
• Vascular Neurology

Background:

• Reversible cerebral vasoconstriction syndrome (RCVS) is a rare neurological disorder.
• It presents with thunderclap headaches and reversible cerebral artery narrowing.
• RCVS is linked to various triggers like medications, drugs, and postpartum state.

Purpose of the Study:

• To review the clinical features, pathophysiology, differential diagnoses, and management of RCVS.
• To emphasize the importance of early recognition and current treatment recommendations for RCVS.

Main Methods:

• Literature review of over 500 published RCVS cases.
• Analysis of associated conditions, complications, and treatment outcomes.

Main Results:

• RCVS is associated with hemorrhagic or ischemic brain lesions in 33-50% of cases.
• Posterior reversible encephalopathy syndrome (PRES) often co-occurs with RCVS.
• Calcium channel blockers may reduce headache intensity but not vasoconstriction; glucocorticoids are contraindicated.

Conclusions:

• RCVS is typically benign and self-limited, but can lead to permanent deficits or death.
• Supportive management, including removal of triggers, is the cornerstone of RCVS treatment.
• Early diagnosis and appropriate management are crucial for improving patient outcomes in RCVS.
