[Neonatal cerebral thrombosis and deficit of factor V leiden].
Background Cerebral venous thrombosis is an inusual disease in neonatal age. Increasing reports of this disorder had described since magnetic resonance angiography is used. Case report Newborn of apropriate seze for gestational age was delivered at 35 weeks of gestation. Refered a severe hipoxic-isquemic disease with multisistemic afectation. The second day of life presented disseminated intravascular coagulation with pulmonary bleeding. The third day, the infant developed seizures that required treatment with diazepam in continuous perfussion. MR angiography visualized superior sagital and transvers sinus thrombosis. Coagulation study detected factor V Leiden. Comments Frecuently venous cerebral thrombosis is presenting with lethargy and seizures. The most common vessels involved are sagital and transvers sinus. It is described in association with exogenous risk factors that increasing blood hyperviscosity and additional inhered coagulation dissorders such as defects on antihrombina III, protein C and S and activate protein C resistance. The last defect has a hight prevalence in subjects with trombosis events.
