ABSTRACT
CLINICAL ISSUE: Clinically, COVID-19 (coronavirus disease 2019) is increasingly seen as a systemic disease associated with multiorgan involvement through a hypercoagulatory condition in the sense of vasculopathy. STANDARD TREATMENT: Treatment with antiplatelet drugs or heparins appears to be indicated. The current evidence, at least for acetylsalicylic acid (ASA), is lacking. DIAGNOSTIC WORK-UP: Corresponding to the significant proportion of primarily microstructural vascular changes, the radiological diagnosis showed not only macrovascular pathologies, but also diffuse perfusion disorders. PERFORMANCE: Regional hypoperfusion in the lungs can be detected with and without pulmonary arterial embolism. Similar findings can be found in almost all organ systems. PRACTICAL RECOMMENDATIONS: A therapeutic intervention using low molecular weight heparins in hospitalized patients in situation-adapted dosage is indicated and is discussed in detail. In the detection of micro- and macrovascular thrombosis in the context of COVID-19, extended radiological diagnostics play a central role and are the basis of adapted therapy and secondary prevention.
