Abstract
BACKGROUND

Hospitalized and severely ill coronavirus disease 2019 (COVID-19) patients necessitate prophylactic or therapeutic anticoagulation to minimize the risk of thrombosis at different sites. Life-threatening bleeding complications include spontaneous iliopsoas hematoma, peritoneal bleeding, and extra-abdominal manifestations such as intracranial hemorrhage.

CASE SUMMARY

Bleeding in the abdominal wall results in less severe complications than seen with iliopsoas hematoma or peritoneal bleeding. In our case series of 9 patients, we present retroperitoneal and abdominal bleeding complications following anticoagulation in hospitalized COVID-19 patients with severe acute respiratory syndrome coronavirus 2 pneumonia. Contrast-enhanced computed tomography (CE-CT) is the best imaging modality for assessing hematoma secondary to anticoagulation and determines the therapeutic approach, whether interventional, surgical, or conservative management.

CONCLUSION

We present the role of CE-CT for rapid and precise localization of the bleeding site and prognostic counseling. Finally, we provide a brief review of the literature.

Core Tip: Hospitalized patients with coronavirus disease 2019 (COVID-19) possess a higher risk for both hypercoagulable state and thrombotic complications due to an imbalance in platelet production and destruction and coagulation system disorders that accompany the pathophysiology of this disease. In line with this, the indication of performing contrast-enhanced multidetector computed tomography may help to identify active hemorrhage as a complication of anticoagulant therapy in hospitalized patients with COVID-19 pneumonia. In addition, pre-contrast scans may define the size and the precise location of suspected hematoma, especially when ultrasound findings are inconclusive.
