摘要
Introduction Esophageal perforation(EP)is a rare but potentially lethal clinical condition with a mortality rate as high as 20%[1].The most common causes of EP are iatrogenic,spontaneous,and foreign body ingestion[2].EP is often accompanied by serious complications such as hemorrhagic pericardial effusion,mediastinal abscesses,and sepsis[3].Management is multidisciplinary and involves emergency physicians,thoracic surgeons,otaorhinolaryngologists,gastroenterologists,anesthesiologists,and radiologists[1].We herein report a case of pneumomediastinum caused by EP and discuss the effect of percutaneous ultrasound(US)-guided drainage through the retropharyngeal space.
