ABSTRACT
Objectives: The aim of our study was to assess the frequency distribution of relevant and incidental vascular events in a retrospective cohort of 42 COVID-19 patients. Methods: All patients were studied by whole-body CT angiography.Twenty-three out of 42 patients were admitted to the intensive care unit (ICU). Results: Relevant vascular events were recorded in the 71.4% of the whole study population. Pulmonary embolism was the most frequent one both in ICU and no-ICU cases (56.5% vs10.5%, p=0.002). Ischemic infarction of other organs was affecting with an increasing prevalence the gut, the spleen, the liver, the brain and the kidney, with a simultaneous ischemic occurrence in some cases. Multi-focal venous thrombosis was also represented especially in ICU patients (p=0.005). Among incidental findings, splanchnic vessels little-size aneurysms were reported in the 40% of the whole population, with relative frequencies similarly distributed in ICU and no-ICU patients.Conclusions: Vascular involvement is not negligible in COVID-19 and should be carefully investigated as may significantly affect disease behavior and prognosis.
