Abstract:

To summarize the nursing experience associated with managing a patient diagnosed with type II Abernethy malformation complicated with pulmonary hypertension，who underwent liver transplantation followed by veno-arterial extracorporeal membrane oxygenation（VA-ECMO）. Based on the pathological and physiological characteristics of pulmonary hypertension following liver transplantation，analgesia and sedation was adopted to protect the organs. The targeted medications in conjunction with ECMO was used to reduce pulmonary artery pressure and improve right heart function. Monitoring oxygenation during ECMO operation along with anticoagulation management and prevention of complications such as lower limb ischemia，individualized fluid therapy to avoid new liver reperfusion syndrome were also implemented. Through meticulous nursing care and multidisciplinary collaboration，the patient successfully recovered and was discharged.
