Pulmonary thromboembolism in mild and asymptomatic COVID-19 cases. A clinical conundrum in post-COVID era

Abstract

We present a case series of patients with pulmonary embolism of unknown etiology who did not have any risk factors. According to the findings, the most likely cause of the pulmonary embolism was undiagnosed, asymptomatic, or mild Corona Virus disease-2019 (COVID-19) infections in the recent past. In the current post-pandemic era, where there has been a surge of sudden unexplained deaths and pulmonary embolism cases, this case series emphasizes the importance of pulmonary embolism evaluation in patients seeking medical care for dyspnea. Physicians should be aware of the possibility of pulmonary embolism as a late complication in patients with mild, asymptomatic, or undiagnosed COVID-19 infection.
