RESUMEN
The Covid-19 pandemic caused by the Sars-Cov-2 virus created challenges and stimulated development of new forms of treatment in many different areas of medicine. Studies have described the clinical characteristics of patients and their outcomes, including disorders affecting the coagulation system, in which patients infected by the virus enter a hypercoagulable and proinflammatory state that mimics vasculitis. The objective of this study was to describe the clinical status and the treatment administered to three patients who developed acute arterial occlusion after Covid-19 infection. The management adopted in these cases enabled the patients to recover without sequelae. The low incidence and scarcity of published reports make it difficult to establish universally accepted treatment criteria and options for cases of ischemia in patients infected with the novel coronavirus, whether presenting early or late.
RESUMEN
Resumo A pandemia causada pela doença do coronavírus 2019 (covid-19) estabeleceu desafios e estimulou o desenvolvimento de diferentes formas terapêuticas em várias áreas médicas. Estudos descreveram características clínicas e desfechos de pacientes, incluindo desordens do sistema de coagulação, em que os pacientes infectados pelo vírus apresentam um estado de hipercoagulabilidade e pró-inflamatório que mimetiza uma vasculite. O objetivo deste trabalho foi descrever o quadro clínico e a terapia empregada em uma série de três pacientes que evoluíram com quadro de oclusão arterial aguda no período pós-infecção por covid-19. O manejo aplicado nesses casos permitiu que os pacientes evoluíssem sem sequelas. A baixa incidência e a pobreza em relatos descritos tornam difícil o estabelecimento de critérios e opções terapêuticas universalmente aceitos nos casos de isquemia, seja precoce ou tardia, dos pacientes infectados pelo novo coronavírus.
