Abstract
OBJECTIVE: The present study seeks to overcome the lack of data on Covid-19 associated intracranial hemorrhage (ICH) in Brazil. METHODS: This is a retrospective, single-center case series of consecutive patients. It is a subanalysis of a larger study still in progress, which covers all neurological manifestations that occurred in patients admitted between March 1st, 2020 and June 1st, 2022, with active SARS-CoV-2 infection confirmed by polymerase chain reaction test. All patients with non-traumatic ICH were included. RESULTS: A total of 1675 patients were evaluated: 917 (54.75 %) had one or more neurological symptoms and 19 had non-traumatic ICH, comprising an incidence of 1.13 %. All patients had one or more risk factors for ICH. The presence of neurological manifestations before the ICH and ICU admission showed a statistically significant relationship with the occurrence of ICH (X(2) = 6.734, p = 0.0095; OR = 4.47; CI = 1.3-15.4; and FET = 9.13; p = <0.001; OR = 9.15; CI = 3.27-25.5 respectively). CONCLUSION: Our findings were largely congruent with the world literature. We believe that the assessment of risk factors can accurately predict the subgroup of patients at increased risk of ICH, but further studies are needed to confirm these hypotheses.
