Concomitant renal and splenic infarction as a complication of COVID-19: a case report and literature review.

The prothrombotic state contributes to diverse and devastating prognoses of severe COVID-19. We describe a unique COVID-19 case with concomitant splenic and renal infarcts. Based on this, clinicians should have a low threshold to suspect a diagnosis of deep vein thrombosis/pulmonary embolism (DVT/PE), especially in the abdominal visceral region if a patient comes in several days after a COVID-19 diagnosis with abdominal pain. Whether or not empiric full dose anticoagulation is needed in patients without definite diagnosis of thromboembolism is still controversial. Further studies need to be done; meanwhile, we advocate the use of regular dose thromboprophylaxis in all hospitalized patients and therapeutic anticoagulation only when there is a confirmed diagnosis of thromboembolism.
