INTRODUCTION: Primary angiitis of the central nervous system (PACNS) and reversible cerebral vasoconstriction syndrome (RCVS) are two rare syndromes that affect the cerebral vasculature. Both conditions have been shown to cause severe neurologic complications. Distinguishing these two conditions in clinical practice is often challenging. Here, we compare the clinical features and outcomes of RCVS and PACNS hospitalizations against the general adult inpatient population.
MATERIALS AND METHODS: We conducted a retrospective review of hospitalizations with a diagnosis of PACNS or RCVS from 2016 to 2018 in the National Inpatient Sample (NIS) database. Multivariate analysis was performed to calculate adjusted odds ratios (ORadj) for hospital outcomes.
RESULTS: In the NIS, 3305 hospitalizations had a diagnosis of RCVS and 6035 hospitalizations had a diagnosis of PACNS. RCVS hospitalizations had a significantly greater association with cerebral aneurysms (ORadj 23.80), hemiplegia/hemiparesis following subarachnoid hemorrhage (SAH) (ORadj 324.09), ischemic stroke (ORadj 7.59), and nontraumatic SAH (ORadj 253.61). PACNS hospitalizations had a significantly greater association with hemiplegia/hemiparesis following cerebrovascular accident (CVA) (ORadj 6.16), ischemic stroke (ORadj 11.55), nontraumatic SAH (ORadj 7.29), seizure (ORadj 2.49), and in-hospital mortality (ORadj 2.85).
CONCLUSIONS: We 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.
