- Abstract
Introduction: Cerebral venous thrombosis (CVT) is an uncommon and clinically heterogeneous cerebrovascular particularly in children, only a few published case series focused in the pediatric population., Patients and Methods: Retrospective single-center observational and analytical study of consecutive pediatric patients admitted in a level II Portuguese hospital with a confirmed diagnosis of CVT, from 2003 to 2021. Clinical presentation, neuroimaging findings, prothrombotic factors, treatment strategies, outcome and recanalization were documented., Results: Twelve children were included (58% female). Mean age was 7.3 years. The most frequent symptoms were vomiting, headache and behavioral alterations. Infection was the triggering factor in 50% of the cases. The diagnosis of CVT was made based on imaging evidence of thrombosis through magnetic imaging resonance (MRI) with venography and/or computed tomography (CT) with venography. In 67% of cases there were multiples sinuses involved; the transverse sinus was the most affected, followed by the sigmoid sinus. In 83% of cases anticoagulant therapy was initiated with low molecular weight heparin (LMWH) and associated prothrombotic factors were investigated, with no major prothrombotic factors identified. No deaths occurred, but 30% had long-term neurological sequelae. One patient recurred 18 years later., Conclusion: The results of this study are consistent with data from other published studies. MRI is the preferred imaging method for diagnosis in children by avoiding ionizing radiation and allowing identification of subjacent causes. Anticoagulation with LMWH is recommended and important to reduce mortality and sequelae. Infectious diseases are the most common trigger for CVT and can also be the cause for high morbidity and poor outcomes., (Copyright © 2022 Sociedad Española de Neurología.
