Spontaneous retroperitoneal hematoma: a rare bleeding occurrence in COVID-19.

ABSTRACT

Emerging evidence suggest that COVID-19 is associated with hypercoagulability, predisposing patients to increase risk of thromboembolism. Anticoagulation is not without its risks of bleeding and decision to initiate anticoagulation should be carefully considered with close monitoring. Spontaneous retroperitoneal hematoma is a rare complication, and there are only a few documented reports implicating anticoagulant or antiplatelet agents as a potential cause. We report a 57-year-old gentleman with COVID-19 pneumonia who developed hypotension on Day 10 of illness while on prophylactic anticoagulation. Computed tomography scan of abdomen revealed a large right retroperitoneal and psoas muscle hematoma and he underwent surgical exploration to evacuate the hematoma. His condition improved and was discharged well. Although prophylactic anticoagulation may reduce thrombotic complications in severely ill COVID-19 patients, a high index of suspicion for rare bleeding complications should be maintained if patients become hemodynamically unstable. Early diagnosis and appropriate intervention may improve outcome and prevent mortality.
