ABSTRACT

El neumopericardio se define por la presencia de aire en la cavidad pericárdica. Puede provocar taponamiento cardíaco. Presentamos el caso de un varón de 21 años, que tras sufrir un accidente de moto, ingresa consciente, inquieto, con trabajo respiratorio marcado, taquipneico y saturación periférica de oxígeno del 88%. Presenta un gran enfisema subcutáneo torácico, especialmente en hemitórax derecho que se extiende al flanco abdominal. La auscultación respiratoria muestra una disminución marcada del murmullo vesicular en hemitórax derecho. Se procede a la intubación orotraqueal inmediata y canalización de una vía central y administración de cristaloides. Se realiza ecografía abdominal y toracocentesis. Se realiza una radiografía de tórax portátil que muestran hemotórax y contusión pulmonar multilobular, así como una imagen de Neumopericardio. El paciente fallece a los 15 minutos del ingreso. La necropsia demostró la presencia de rotura de aorta torácica, y se mantuvo una duda razonable respecto a la causa inmediata de la muerte, taponamiento cardíaco secundario al neumopericardio o shock hipovolémico hemorrágico (AU)


Pneumopericardium is defined as the presence of air within the pericardial sac; it may be the cause of cardiac tamponnade. We here report the case of a 21-year-old male who, after suffering a motorcycle accident, was admitted to hospital conscious but anxious, with marked dyspnoea and tachypnoea and with a peripheral oxygen saturation level of 88%. The clinical examination disclosed marked thoracic subcutaneous emphysema mainly on the right haemithorax and extending to the side of the abdomen. On auscultation there was a marked diminution of the vesicular murmur in the right haemithorax. Orotracheal intubation was performed immediately and a central venous access catheter was inserted with crystalloid administration. An abdominal ultrasound scan and thoracocentesis were performed. The plain chest film (portable apparatus) disclosed haemothorax and multilobar lung contusion and an image highly suggestive of pneumopericardium. The patient died 15 minutes after admission. The Forensic Pathology examination (the report was received later) demonstrated rupture of the thoracic aorta and posed reasonable doubts as to the immediate cause of death: cardiac tamponnade secondary to the pneumopericardium or haemorrhagic hypovolaemic shock (AU)
