Reversibles zerebrales Vasokonstriktionssyndrom

Reversible cerebral vasoconstriction syndrome (RCVS) is a complex and etiologically diverse neurovascular disorder that typically presents with severe thunderclap headaches (TCH) as the primary symptom, accompanied by reversible vasoconstriction of the cerebral arteries. The clinical course may include focal neurological deficits or epileptic seizures. There are two types: idiopathic RCVS and secondary RCVS, the latter triggered by various substances, medical interventions, or diseases. In clinical practice, various medical specialists may initially encounter this condition, underscoring the importance of accurate recognition and diagnosis of RCVS. The clinical course often appears monophasic and self-limiting, with recurrences reported in only 1.7% of cases annually. Complications such as cerebral hemorrhages and cerebral ischemia can lead to death in 5–10% of cases. This article utilizes a case study to explore RCVS, its complications, and the diagnostic procedures involved.
