Primary angiitis of the central nervous system and reversible cerebral vasoconstriction syndrome: analysis of the National Inpatient Sample

ConclusionsWe performed an analysis of the NIS to better understand RCVS and PACNS hospitalizations. Severe neurologic events including CVA and SAH were elevated in both, but SAH and related hemiplegia/hemiparesis were extremely common among RCVS hospitalizations. In-hospital mortality was elevated in PACNS but not RCVS. This information can be used to help clinicians better understand, distinguish, and diagnose these conditions.Key Points•Despite clear description of RCVS and PACNS in the medical literature, there remains a scarcity of national population-based studies comparing these two entities against the general adult inpatient population.•This study aims to fill knowledge gaps in this area.•Here, we compare the clinical features and outcomes of RCVS and PACNS hospitalizations against the general adult inpatient population.
