奇闻|牛!牛英格兰,还真把肺给咳出来,您信吗?
其实不是肺,文献说是支气管血栓铸型,硬生生的被咳出来了!?
您信吗?不管您信不信,反正我不太信。
那天,ROOT_C_K兄发表《心衰咳出支气管树样血栓》的帖子心衰咳出支气管树样血栓
我读后不信,以为是假的。
多谢图图版主教导,告知我这是文献中的。
我一直以为那张图片应该是尸解标本的支气管铸型,活人怎么可能咳出这么大的东西,不应该窒息憋死的么?
未曾想,这个事据说是真的,而且还发表在New England Journal ofMedicine (NEJM),不愧是牛英格兰,牛!
原图如下:
原文如下:
A 36-year-old man was admitted to the intensive care unit with an acute exacerbation of chronic heart failure. His medical history included heart failure with an ejection fraction of 20%, bioprosthetic aortic-valve replacement for bicuspid aortic stenosis, endovascular stenting of an aortic aneurysm, and placement of a permanent pacemaker for complete heart block. An Impella ventricular assist device was placed for management of acute heart failure, and a continuous heparin infusion was initiated for systemic anticoagulation. During the next week, the patient had episodes of small-volume hemoptysis, increasing respiratory distress, and increasing use of supplemental oxygen (up to 20 liters delivered through a high-flow nasal cannula). During anextreme bout of coughing, the patient spontaneously expectorated an intact castof the right bronchial tree. The right bronchial tree consists of three segmental branches in the upper lobe (blue arrows), two segmental branches in the middle lobe (white arrows), and five segmental branches in the lower lobe(black arrows). The patient’s trachea was subsequently intubated, and flexible bronchoscopy revealed a small amount of blood in the basilar branches of theright lower lobe. The patient was extubated 2 days later and had no further episodes of hemoptysis. One week after extubation, he died from complicationsof heart failure (volume overload and poor cardiac output) despite placement ofthe ventricular assist device.
译文如下:
患者男性,36岁,因慢性心力衰竭急性发作收住ICU。
既往病史包括慢性心衰(LVEF=20%)、二叶式主动脉狭窄生物瓣置换术后、主动脉瘤腔内隔绝术后,及AVB Ⅲ度永久起搏器植入术后。
使用左室辅助装置Impella纠正急性心衰,并持续静脉输注肝素用于全身抗凝。
在接下来的一周里,患者间歇出现少量咯血,呼吸困难逐渐加重,给氧量增加(高流量鼻导管吸氧高达20升/min)。
在一次剧烈咳嗽时,病人自行咳出了完整的右支气管树血栓铸型。
右支气管树由上叶3个肺段支气管(蓝色箭头)、中叶2个肺段支气管(白色箭头)和下叶5个肺段支气管(黑色箭头)组成。
随后为病人行气管插管,可弯曲支气管镜显示右肺下叶基底段支气管内有少量血液。
病人在2天后拔除气管插管,未再出现咯血。
尽管使用了左室辅助装置,拔管一周后,该患仍死于心衰并发症(容量超负荷和心输出量不足)。

不由得想起《九品芝麻官》,痨鬼娶亲时,就站在周星驰背后剧烈咳嗽,一不留神真的咳出一团不知道是肝还是肺的东西,好不恶心。
看到那张图片,完全不相信,怎么会这么完整,经过图图兄提醒才知道这是NEJM几天前发表的case,去围观,果真有。
再复习一下,右肺支气管树解剖知识:
