RESUMO

OBJECTIVE: The objective of this study was to determine if there are differences between the presentation patterns of hemorrhagic stroke (HS) associated to COVID-19. METHODS: It was performed a systematic search based on PRISMA guidelines of the cases reported in PUBMED of HS associated to SARS-CoV-2 infection and we added to this sample cases from our own hospital cohort. Patients in the database were separated by groups according to presentation symptoms: if they debuted with neurological symptoms or debuted with pulmonary symptoms. RESULTS: Seventy cases were included in the study. Patients that debuted with pulmonary symptoms accounted for 68.6% of the cases with an interval between the development of symptoms and the presentation of HS of 15.6 days. We found that the use of anticoagulants during hospitalization, multifocal image pattern, and the elevation of D-dimer, Ferritin, and lactate dehydrogenase levels were significantly associated with the group of pulmonary presentation, whereas the presence of hypertension during hospitalization, and a lower hemoglobin level was associated with the group of neurologic symptoms. CONCLUSION: Although HS associated with COVID-19 is a clinical entity with increasing evidence, it is necessary to establish that there are two forms of presentation with their own characteristics.


OBJETIVO: determinar si existen diferencias entre los patrones de presentación de hemorragia intracraneal asociada a COVID-19. PACIENTES Y MÉTODOS: Se realizó una búsqueda sistemática basada en la guía PRISMA de los casos reportados en PUBMED de hemorragia intracraneal asociados a infección por SARS-CoV-2 y se agregaron a esta muestra casos de nuestra propia cohorte hospitalaria. RESULTADOS: se incluyeron 70 casos. Los pacientes que debutaron con síntomas pulmonares representaron el 68.6% de los casos con un intervalo entre el desarrollo de los síntomas y la presentación de la hemorragia intracraneal de 15.6 días. Encontramos que el uso de anticoagulantes durante la hospitalización, el patrón de imagen multifocal y la elevación de los niveles de dímero D, ferritina y deshidrogenasa láctica se asociaron significativamente con el grupo de presentación pulmonar, mientras que la presencia de hipertensión durante la hospitalización, y un nivel de hemoglobina más bajo se asoció con el grupo que debutó con síntomas neurológicos. CONCLUSIÓN: si bien la hemorragia intracraneal asociada a COVID-19 es una entidad clínica con evidencia creciente, es necesario establecer que existen dos formas de presentación con características propias.

RESUMO

INTRODUCCIÓN: en la actual pandemia de COVID-19, existe evidencia creciente que ha identificado el neurotropismo del virus SARS-CoV-2 y sus complicaciones neurológicas, incluida la enfermedad cerebrovascular isquémica y escasamente hemorragia cerebral (HC). OBJETIVO: describir las características clínicas, radiológicas, de laboratorio y pronósticas de los pacientes con HC asociada al SARS-CoV-2. MÉTODOS: se incluyeron pacientes consecutivos con prueba de PCR confirmatoria para infección por SARS-CoV-2 y HC. RESULTADOS: en un período de 90 días, en un centro de referencia COVID-19 en México, de 1108 pacientes con infección por SARS-CoV-2, se encontraron 4 pacientes (0.36%) con HC. Tenían una edad de 71(±12.2) años, 2 eran mujeres. Se encontró que dos tenían factores de riesgo cardiovascular previos. En dos casos se encontró el origen en el núcleo dentado mientras que los otros dos correspondieron al tálamo. Tres de los cuatro pacientes murieron. Postulamos que el descontrol hipertensivo, coagulopatía, trombocitopenia y la respuesta inmune inducida por el virus SARS-CoV-2 podrían desencadenar HC en un paciente con riesgo previo. CONCLUSIONES: la HC se asocia a la infección por SARS-CoV-2 con mal pronóstico cuando se presenta. Los equipos de neurocirugía deben estar preparados para el tratamiento oportuno de estos pacientes. INTRODUCTION: In the current COVID-19 pandemic, there is a growing body of evidence that has identified the neurotropism of the SARS-CoV-2 virus and its neurological complications, including cerebrovascular disease, focusing mainly in ischemic and scarcely about hemorrhagic stroke (HS). OBJECTIVE: The objective of the study was to describe clinical, radiological, laboratory tests, and prognostic characteristics of patients with SARS-CoV-2 associated HS. METHODS: Consecutive patients with a confirmatory PCR test for SARS-CoV-2 infection and a HS demonstrated by head CT were included in the study. RESULTS: Over a period of 90 days, in a COVID-19 reference center in Mexico, out of a total of 1108 patients with SARS-CoV-2 infection, it found 4 patients (0.36%) who meet criteria. They had an age of 71 (±12.2) years, 2 were women. It was found that two had prior cardiovascular risk factors. Two of the HS originated in the dentate nucleus while the other two corresponded to the thalamus. Three of the four patients died. We suggest that catastrophic uncontrolled blood pressure, coagulopathy, thrombocytopenia, and immune response induced by SARS-CoV-2 could in a specific patient trigger HS. CONCLUSIONS: HS is associated to SARS-CoV-2 infection with poor prognosis when it presented. Neurosurgery teams should prepare for the timely and appropriate treatment of this patients.
