Pulmonary arterial thrombosis

In an autopsy study of 11 COVID-19 patients in Austria, “the most striking and unexpected finding was the obstruction of pulmonary arteries by thrombotic material present at both the macroscopic and microscopic level in all cases,” researchers report in the Annals of Internal Medicine. These thromboses were frequently associated with pulmonary infarction and bronchopneumonia. Of note, 10 of the 11 patients had received prophylactic anticoagulation (although venous thromboembolism had not been suspected in any of them).
