Survival after Cardiac Arrest Secondary to Massive Pulmonary Embolism

Abstract

Introduction . It is estimated that the diagnosis of pulmonary embolism (PE) is missed in as many as 84% of all cases of PE. Cardiac arrest following PE is generally associated with poor outcomes. Case Report . A 43-year-old man presented to the Emergency Department (ED) in cardiac arrest. Swelling of his right lower limb was noted on arrival. Point of care ultrasound was performed during ongoing cardiopulmonary resuscitation (CPR) and showed a thrombus in the right iliofemoral vein as well as dilatation of the right ventricle. Fibrinolytic therapy was initiated immediately and a return of spontaneous circulation (ROSC) was achieved 30 minutes later. The diagnosis of PE was finally confirmed on computed tomography pulmonary angiography once haemodynamic stability was achieved. The patient was thereafter transferred to the intensive care unit for postresuscitation care and further management. Several days later, he was discharged home neurologically intact and fully recovered. Discussion . Since outcomes after cardiac arrest following PE are generally dismal, available and potentially life-saving interventions to restore pulmonary circulation should be rapidly implemented when PE is the likely cause of cardiac arrest.
