Pulmonary thromboembolism in COVID-19: Evaluating the role of D-dimer and computed tomography pulmonary angiography results

COVID-19 patients have a strong propensity to develop thrombosis and their respiratory symptoms often prompt clinicians to assess for the presence of a pulmonary thromboembolism (PTE) [1,2]. Prior research estimates that approximately 20% to 30% of patients with COVID-19 have a PTE demonstrated by computed tomography pulmonary angiography (CTPA) [3,4]. Some clinical decision rules such as the Pulmonary Embolism Rule-Out Criteria (PERC) and Wells' Criteria are used to assess a patient's risk of PTE.
