ABSTRACT
As the COVID-19 pandemic continues, its novel complications are being increasingly recognized, and new mechanisms of the disease are being unraveled. Aortic free-floating thrombus is exceptionally rare, and prompt diagnosis is vital to alleviate its detrimental end organ effects. We present a patient who was previously discharged owing to COVID-19 pneumonia, admitted with acute onset of lower limb pain, and was diagnosed with aortic free-floating thrombus ended up with embolic events. Clinicians should be aware of COVID-19-related thromboembolic complications, and close monitoring of patients with risk factors is vital for a timely and accurate diagnosis and management.

The goal of the present work was to examine associations between COVID-19 pneumonia severity and pulmonary artery diameter. A total of 101 patients with COVID-19 were included in this retrospective observational study. The patients were divided into three groups based on the CT images: 41 patients with mild pneumonia, group 2 had 39 patients with moderate pneumonia, and group 3 had 21 patients with severe pneumonia. Furthermore, the diameter of the main pulmonary artery was calculated as well as ascending aorta, right and left pulmonary artery diameters. Laboratory analysis results were also compared. Analyses show an increased main pulmonary artery diameter is associated with poorer prognosis for patients with COVID-19 pneumonia. Further studies are needed into the mechanisms between severe hypoxemia, increased inflammation, and vascular resistance and higher numbers of thromboembolic events.
