| Summary: | Background & Objectives: The literature on cerebral venous thrombosis (CVT) in South East Asia is limited. The objectives were to evaluate the clinical profile, predisposing factors and clinical outcome of the CVT patients in Malaysia. Methods: We conducted a retrospective descriptive study of the CVT patients admitted to the neurology ward. The clinical presentation, predisposing factors, radiological findings, treatment and prognostic characteristics were evaluated from the charts. Clinical outcome on discharge and six months was measured by Modified Rankin Scale (mRS) scores. Poor outcome and good outcome was defined as Modified Rankin Scale (mRS) scores of 3-6 and 0-2 respectively. Results: Forty nine CVT patients who presented between 2007 and 2017 were recruited. The mean age was 43.51 +/- 16.52. The patients consisted of 39 Malaysians (13 Indians, 12 Malays, 12 Chinese, one Iban, one Eurasian descent), and ten non-Malaysians. Thirty (61.2%) patients were women. The most common presenting complaint was headache (75.5%). Six percent had multiple risk factors, whereas 51% had idiopathic CVT. The most common predisposing factors were oral contraceptive pill use (18.4%), followed by infection (12.2%), especially central nervous system (CNS) infection (6.1%); 11.8% had prothrombotic disorder. The most common location for CVT was superior sagittal sinus (83.7%). On neuroimaging, 77.6% had parenchymal lesions, 53.1% had venous infarcts and 38.8% had intracerebral haemorrhage, one patient had CVT complicated by rare venous collateral channels. Poor outcome on discharge and at six months was 38.8% and 33.3% respectively. On univariate analysis, female gender (p=(1.002), seizures (p=0.037) and cerebral oedema (p=0.018) were associated with poor functional outcome. On binary logistic regression, female gender (OR=14.50, 95% CI 2.10-99.94, p=0.003) and seizures (OR=6.54, 95% CI 1.33-32.07, p=0.017) were associated with poor outcome.Conclusion: The CVT patients in this study had a higher proportion of CNS infections. Poor outcome was independently associated with female gender and seizures. |
