Infection by SARS-Cov-2 is mainly characterized by fever and respiratory symptoms, with dyspnea and lung infiltrates in more severe cases[1,2]. Many patients also present a procoagulant state, which is biochemically detected by increased D-dimer levels and is related to complications and a worse prognosis[1]. Accordingly, some authors have suggested that pulmonary embolism (PE) is more common in patients with COVID-19 than in the uninfected population[3–7]. A recent meta-analysis of 66 studies that included 23,117 COVID patients that had been hospitalized reported a PE prevalence rate of 7.8% (95% confidence interval [CI]=6.2–9.4)[8].
