Introduction: Cerebral venous sinus thrombosis (CVST) represents an important cause of both ischemic and hemorrhagic strokes in young people. While recent guidelines recommend management in a stroke unit, the impact of Neurocritical care in this condition has not been studied. We aimed to assess whether the introduction of a Neurocritical Care program influenced clinical outcomes in CVST patients.
Methods: We retrospectively reviewed electronic medical records of adult patients admitted to Yale New Haven Hospital’s Neuroscience ICU (NICU) between 2010 and 2017 with a diagnosis of CVST. Demographics, vascular risk factors, comorbidities, length of stay and discharge modified Rankin scale (mRS) were collected. Patients were excluded for transfer after 24 hours of initial presentation. We compared two time periods, before (epoch 1, 2010-2012) and after (epoch 2, 2013-2017) the introduction of continuous staffing of CVST cases by neurointensivists in the NICU. Univariable and multivariable logistic regression were utilized to model the odds of poor outcome (dichotomized mRS 0-2 vs 3-6).
Results: Fifty-three patients with CVST met the inclusion criteria during the study period (mean age 39 (+/- 17) years, 51 % female). 20 patients were identified for Epoch 1 and 33 patients for Epoch 2. Overall, 40 patients (76%) had a good (mRS 0-2) outcome. For epochs 1 and 2, good outcomes were observed in 12 (60%) and 28 (85%) patients, respectively (p=0.04). In both univariable and multivariable regression analysis (adjusted for age and sex), admission during epoch 2 was associated with a significantly reduced odds of a poor outcome (OR 0.27, CI 0.07 - 0.98; p =0.048) and (OR 0.27, CI 0.07- 1; p=0.05), respectively.
Conclusions: In this small, single-center cohort of patients with CVST, most patients experienced a good outcome. The institution of continuous neurointensivist coverage was independently associated with better outcomes. Further validation in prospective, multicenter cohort studies is needed.
