A 54-year-old woman who underwent chest tube placement after a lung biopsy was found on the first postoperative day to have ipsilateral ptosis and miosis, suggesting a Horner syndrome. A chest CT scan showed that the tip of the chest tube was apposed to the stellate ganglion. Repositioning of the chest tube later on the first postoperative day led to complete reversal of the Horner syndrome within 24 hours. We propose that the Horner syndrome arose as a result of pressure on the stellate ganglion, which interrupted neural conduction but did not sever the sympathetic pathway ("neurapraxia"). Whether prompt repositioning of the chest tube was critical in reversing the Horner syndrome is uncertain.
一名54岁女性在肺活检后接受了胸管置入，术后第一天发现同侧上睑下垂和瞳孔缩小，提示霍纳综合征。胸部CT扫描显示胸管尖端靠近星状神经节。术后第一天晚些时候重新放置胸管，导致霍纳综合征在24小时内完全逆转。我们认为霍纳综合征是由于星状神经节受压所致，这中断了神经传导，但未切断交感神经通路（“神经失用症”）。胸管的及时重新放置对于逆转霍纳综合征是否至关重要尚不确定。
