ABSTRACT
AIM: Intracerebral hemorrhage (ICH) is one of the most severe complications of thrombolysis. Symptomatic ICHs are associated with adverse outcomes. It has been reported that symptomatic ICHs most commonly occur within the first few hours after the initiation of intravenous thrombolysis. Our aim here was to determine the risk factors for early ICH (within 12 h) after thrombolysis. METHODS: We analyzed patients with acute ischemic stroke who received intravenous alteplase at two hospitals affiliated to Wenzhou Medical University between March 2008 and November 2017. The ICH diagnosis time was defined as the time from the intravenous administration of alteplase to the first detection of hemorrhage on computed tomography. Demographic data, medical history, clinical features, and laboratory examination results were collected. Univariate analysis followed by multivariable logistic regression analysis was performed to determine the predictors of early ICH (within 12 h) after thrombolysis. RESULTS: Among 197 patients, early ICH (within 12 h) after thrombolysis occurred in 13 patients (6.6%). In the univariate analysis, patients with early ICHs were significantly correlated with prior stroke (P=0.04). After adjusting for potential confounders in the multivariate analysis, prior stroke (odds ratio [OR]: 5.752, 95% confidence interval [CI]: 1.487-22.248; P=0.011) and atrial fibrillation (OR: 5.428, 95% CI: 1.427-20.640; P=0.013) were associated with early ICH. CONCLUSIONS: Prior stroke and atrial fibrillation are independent risk factors for early ICHs (within 12 h) after intravenous thrombolysis with alteplase.

RESUMEN La encefalitis por herpes virus simple es la causa más común de encefalitis esporádica letal en el mundo. Una complicación poco usual es la hemorragia intracerebral. Se describe el caso de un preescolar de tres años que ingresa con cuadro clínico de encefalitis aguda, con hallazgos de hemorragia intracerebral temprana en región occipital y estudio en líquido cefalorraquídeo positivo para herpes virus tipo 1, que recibe tratamiento con aciclovir; sin embargo, cursa con evolución tórpida, incremento de hemorragias intracerebrales y desenlace fatal.
ABSTRACT Herpes simplex encephalitis is the most common cause of sporadic lethal encephalitis in the world. Intracerebral hemorrhage is an uncommon complication. The case of a 3-year-old preschooler who was admitted with acute encephalitis clinical picture is described. The patient presents findings of early in tracerebral hemorrhage in the occipital region and a positive cerebrospinal fluid study for herpes virus type 1, which is treated with acyclovir; however, it presents a torpid evolution, increased intracerebral hemorrhages and fatal outcome.
