Abstract
BackgroundRetroperitoneal and rectus sheath hematomas can occur spontaneously. There is a lack of research about the disease progression, optimal treatment strategies and the need for surgical intervention. Our study investigated their outcomes and management. Study designAdult patients admitted during a one-year period with non-traumatic retroperitoneal or rectus sheath hematomas were retrospectively identified. Biographical, hospital-course, and outcome data were extracted. Results99 patients were included; median age was 73-years (IQR 61–80). 88 patients were on an anticoagulant or antiplatelet agent. Warfarin and intravenous heparin being the most commonly utilized agents (42% and 36.4%, respectively). All 99 patients were diagnosed by CT scan. 79 patients received some sort of blood product (79.8% PRBC, 43.4% FFP, 17% platelets), and 26 patients were in hemorrhagic shock. 17 patients underwent angiography and/or angioembolization. Neither anticoagulation in general nor any specific agent was associated with the need for blood product transfusion or angiography. 13 patients died but none were attributable to the hematoma. ConclusionBoth hematomas are usually self-limiting and rarely require surgical intervention. A subset may require angioembolization.
