A rare but mortal condition: case series of three COVID-19 patients with spontaneous rectus sheath hematoma

Coronavirus disease 2019 (COVID-19) could emerge not only as viral pneumonia but also as a cardiovascular disease. Thromboprophylaxis has been recommended by the current guidelines, especially COVID-19 patients who are hospitalized. On the other hand, these drugs might cause serious bleeding complications. Hereby, we aimed to report three cases with spontaneous rectus sheath hematoma (RSH) developed after being administered thromboprophylaxis for severe COVID-19 pneumonia. In this case series, we draw attention to the rare, but mortal complication of the COVID-19 thromboprophylaxis regimen.
