Abstract
This is a 61-year-old man with end-stage liver disease who experienced cardiac arrest secondary to a massive pulmonary embolus and intracardiac thrombus during cannulation for veno-venous extracorporeal membrane oxygenation (ECMO) in preparation for orthotopic liver transplantation (OLT). Surgery was aborted and the patient was taken back to the intensive care unit in cardiogenic shock on multiple vasopressors. The patient was unresponsive to heparin bolus and too high risk for systemic thrombolytics or embolectomy. He was ultimately treated with 12 mg total of alteplase through his pulmonary artery catheter over 3 hours. He had subsequent resolution of his cardiogenic shock and proceeded with successful liver transplantation 5 days after his initial event without any bleeding complications. Low-dose thrombolytic therapy in the setting of absolute contraindications to thrombolysis allowed for recovery of cardiac function and, ultimately redo OLT in a patient with otherwise little hope of survival.
