Background: Retroperitoneal hemorrhage is a rare and severe complication in patients undergoing extracorporeal membrane oxygenation (ECMO). Retroperitoneal hematoma after the operation of multiple ECMO in a single center at the same time is extremely rare. The causes and treatment options can provide clinical experience and bring some inspiration.Case presentation: Three cases of retroperitoneal hemorrhage patients with Corona Virus Disease-19 (COVID-19) are introduced; they had respiratory failure and were treated with veno-venous ECMO or veno-arterial-venous ECMO. Retroperitoneal hemorrhage occurred during ECMO treatment. Among the three cases, 2 cases were found due to abdominal pain, and 1 case was found because of a decrease in ECMO circuit flow rate and hemoglobin level. 2 cases were treated with transcatheter arterial embolization, and 1 case was treated conservatively. The hemorrhage in each of the 3 cases did not deteriorate. Through early diagnosis and treatment, satisfactory treatment results were achieved for these 3 patients.Conclusions: During the period of ECMO treatment, there is a low incidence of retroperitoneal hematoma, yet it comes with a high risk. This is due to anticoagulant use and some local mechanical injuries. If a decline in blood flow velocity and hemoglobin is detected, retroperitoneal hematoma should be taken into consideration, and early aggressive therapy should be started. |
