Abstract
SARS-CoV-2 causes a hypercoagulable state that predisposes patients to thromboembolic events. We report two adolescents with sickle cell disease who developed pulmonary embolism during an acute chest syndrome episode associated with a possible SARS-CoV-2 infection. Both sickle cell disease and SARS-CoV-2 infection predispose to thromboembolic disease. Thromboprophylaxis with low molecular weight heparin should be considered in adolescent with acute chest syndrome, related or not to COVID-19 disease.
