[Reversible cerebral vasoconstriction syndrome]

Reversible cerebral vasoconstriction syndrome (RCVS) is increasingly recognized. The condition is characterized by multifocal vasoconstriction lesions in cerebral arteries. Headache is the central symptom, with an acute onset and paroxysmal occurrence. Some of the patients develop intracranial hemorrhage, ischemic disturbance of the cerebral circulation, hypertensive encephalopathy (PRES) or epileptic seizures as complications. The disease is most common in middle-aged women. Most patients have an underlying predisposing factor, most commonly vasoactive medications, drugs or puerperium. There is no evidence-based practice.
