Clinico-epidemiological profile & outcome of patients presenting with cerebral venous thrombosis to emergency department.

Objectives: To better understand the clinical and radiological characteristics of Cerebral Venous Thrombosis (CVT), we conducted a study focusing on the assessment of neurological outcomes and factors associated with poor prognosis in patients with CVT.
Methods: This prospective, observational study took place over two years (July 2020 to June 2022) in a tertiary care teaching hospital in South India, encompassing adults aged 18 years and over. Key data points included demographic information, symptomatology, physical and neurological examinations, neuroimaging findings, hospital interventions, and neurological outcomes at discharge and at a six-week telephonic follow-up.
Results: A total of 140 patients with CVT, median age 34 years, were studied. 61.4 % were males. The most common symptoms and signs were headaches (70.7 %) and papilledema (60.7 %). Hemorrhagic infarct was the most prevalent finding on the non-contrast computed tomography (NCCT) of the brain, involving 39.4 % of patients. The most commonly affected sinus was the superior sagittal sinus. Risk factors most often observed were alcoholism (45 %), smoking (21.4 %), anemia (27.1 %), oral contraceptive pill usage (12.1 %), and hypertension (12.1 %). Deep vein thrombosis or pulmonary embolism was present in 5 % of the patients. The mean hospital stay was 13.9 days, with 6.4 % of patients requiring endotracheal intubation at presentation and 22.9 % during their stay. The observed in-hospital mortality rate was 17.9 %, increasing to 22.4 % at the six-week follow-up. Morbidity (mRS 3-5) was 24.3 % at discharge, decreasing to 8.2 % at six-week follow-up. Favorable outcomes were reported in 57.9 % of cases at discharge, rising to 69.4 % at six weeks.
Conclusions: Our study underscores the importance of recognizing cardinal symptoms and diverse risk factors of CVT, including alcoholism and anemia. Majority of CVT occurrences were observed in males aged 18-29. Critical determinants of heightened morbidity and mortality were identified, including lower GCS scores and the necessity for advanced interventions. Notably, majority of patients presented favorable neurological outcomes at six-week follow-up.
