Multiple Systemic Embolization Associated with Chest Compression in a Patient with Cardiac Arrest.

Abstract

The patient was an 80-year-old woman with chronic atrial fibrillation, chronic heart failure, cerebellar infarction, hyperlipidemia, and hypertension, who suddenly collapsed while playing gateball outdoors. The doctor at a nearby clinic doctor found her in a state of cardiopulmonary arrest and started basic life support. Twelve minutes after discovery, spontaneous circulation returned. On arrival, she was in a deep coma state with atrial fibrillation-related tachycardia. A physical examination revealed pulseless right radial and left popliteal arteries with cyanosis. Whole-body-enhanced computed tomography and head magnetic resonance imaging demonstrated multiple ischemic organs. Taken together, it was considered that a massive-free thrombus from the left atrium, which was caused by atrial fibrillation, had first obstructed the left ventricular outflow tract, resulting in cardiac arrest. Then, the thrombus had been scattered throughout the body by chest compression. Her condition was judged to be irreversible and she died on day 3. This is the first reported case of multiple systemic embolization associated with chest compression in a patient with cardiac arrest. This unique case adds one more cause to the list of the documented etiologies of complications caused by chest compression.
