Central venous catheters are commonly used in the management of critically ill patients. This case report described a rare but potentially fatal complication of central venous catheter use. A 52-year-old man underwent mechanical aortic valve replacement for infective endocarditis. On day 8 postoperatively he accidentally removed his catheter and collapsed with symptoms and signs suggestive of a cerebral air embolism. A transthoracic echocardiogram showed air bubbles in both the right and left ventricles of the heart confirming the presence of a paradoxical air embolism.
中心静脉导管常用于危重症患者的治疗。本病例报告描述了中心静脉导管使用过程中一种罕见但可能致命的并发症。一名52岁男性因感染性心内膜炎接受了机械主动脉瓣置换术。术后第8天，他意外拔除了导管，随后出现症状并体征提示脑空气栓塞，进而晕倒。经胸超声心动图显示心脏左右心室均有气泡，证实存在反常空气栓塞。
