Abstract

Intracranial hemorrhage (ICH) is the most common neurologic complication of reversible cerebral vasoconstriction syndrome (RCVS). In this study, we compared hemorrhagic and non-hemorrhagic RCVS with an aim to evaluate the risk factors and short-term clinical outcomes of hemorrhagic lesions. We used the Nationwide Readmissions Database 2016–2017 to identify all hospitalizations due to RCVS. Predictors and clinical outcomes of ICH were analyzed using logistic regression analysis. Among the total 1834 hospitalizations for RCVS during the study period (mean ± SD age:48.4 ± 15.6 years, female:75.8%), 768 (41.9%) had occurrence of ICH. Patients with ICH were more likely to be female (OR:2.72, 95% CI:1.86–3.97), have a history of hypertension (OR:1.63, 95% CI:1.20–2.22) and cocaine use (OR:3.11, 95% CI:1.49–6.51), and were less likely to have a history of diabetes (OR:0.52, 95% CI:0.32–0.84) and heart failure (OR:0.34, 95% CI:0.14–0.84). Hemorrhagic RCVS was associated with higher odds of cerebral edema (OR:10.71, 95% CI:5.75–19.97), new onset seizure (OR:2.24, 95% CI:1.08–4.61), respiratory failure (OR:2.40, 95% CI:1.37–4.22) and gastrostomy tube placement (OR:3.20, 95% CI:1.07–9.58). Patients with hemorrhagic lesions also had longer length of hospital stay (mean difference 5.5 days), higher hospital charges (mean difference $105,547), and a lower likelihood of discharge to home (OR:0.61, 95% CI:0.43–0.86). There was, however, no significant difference in the in-hospital mortality. ICH affects nearly 42% of patients with RCVS and is associated with increased rate of other neurologic complications and adverse discharge disposition, thus putting into question the prevailing conception that RCVS is generally a benign disorder with a self-limiting clinical course. •Nearly 42% of patients with RCVS have intracranial hemorrhage.•Female sex and history of cocaine use are associated with intracranial hemorrhage in RCVS.•Patients with hemorrhagic RCVS have worse clinical and functional outcomes.
