Successful laparotomy for intra-abdominal hypertension following veno-venous extracorporeal membrane oxygenation after severe thoracoabdominal trauma: a case report

Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) is often used as a life-saving therapy for lung injuries; however, it presents challenges, including bleeding risks and potential reductions in ECMO flow. This case report details the intricate management of a 16-year-old boy who suffered severe thoracoabdominal trauma following a nine-floor fall. The patient sustained severe lung injury and damage to multiple solid organs, including liver lacerations, and was placed on VV-ECMO. When initiating ECMO, it is crucial to carefully consider anticoagulation to avoid potential bleeding complications. Therefore, despite the usual risks associated with ECMO, such as bleeding and reduced flow rates, anticoagulation was withheld due to the risk of hemorrhage from the liver injury. While on ECMO support, the patient experienced a sudden decrease in flow and blood pressure, suggesting an increase in intra-abdominal pressure. An immediate decompressive laparotomy revealed a significant hemoperitoneum, primarily caused by oozing from the liver laceration. The prompt recognition of abdominal distension and the timely decision to proceed with surgery without further imaging were key to the successful treatment. Postoperatively, the patient showed good recovery, with gradual weaning from ECMO, extubation, and eventual discharge. In conclusion, this case highlights the importance of ongoing monitoring for patients with complex trauma who are on ECMO. External factors, including elevated intra-abdominal pressure, can impair ECMO performance. Meticulous management and a multidisciplinary approach are essential in these intricate cases, which involve the nonsurgical treatment of solid organ damage accompanied by severe lung injury.
