《急诊每日一题》提示脑动脉瘤的完全动眼神经麻痹2022年1月
Question 问题:
A patient with a complete CN III palsy with pupil involvement has an aneurysm until proven otherwise. If the CTA is normal, the standard is to transfer to a hospital with interventional radiology for angiogram. What are the ocular findings on exam?
累及瞳孔的完全动眼神经麻痹患者一定要按动脉瘤处理。如果CT动脉造影正常,标准方案是将患者转到可以做血管造影的介入放射科医院。体检时眼部体征是什么?
Answer 答案:
Ptosis is present; eye position is “down and out”; The pupil is larger than the contralateral pupil, and may be fixed.
眼睑下垂;眼球位置为向下和向外;患侧瞳孔比对侧大,并且无对光反应。
