Abstract: Elongated styloid process is the main anatomical abnormality leading to carotid dissection, and the patient with ischemic stroke caused by carotid dissection associated with elongated styloid process was reported here. The patient had a long-standing history of frequent head down and head lift work and CTA with three-dimensional reconstruction showed bilateral elongated styloid processes. Left internal carotid artery dissection due to long-term mechanical injury was the underlying cause of this ischemic stroke, and arterial dissection was repaired well after stenting in the left internal carotid artery. Adequate attention should be paid to ischemic stroke associated with styloid process syndrome to reduce the risk of recurrent stroke. 

Key words: Ischemic stroke; Internal carotid artery dissection; Styloid process syndrome; Elongated styloid process  

摘要： 茎突过长是导致颈动脉夹层的主要解剖学异常，本文报道1例茎突过长相关颈动脉夹层导致缺血性卒中患者的诊治过程。该患者有长期的频繁低头和抬头工作史，CTA三维重建证实存在双侧茎突过长，长期机械性损伤导致左侧颈内动脉夹层，是本次缺血性卒中发生的根本原因，经左侧颈内动脉支架置入术后动脉夹层修复良好。茎突综合征相关的缺血性卒中应该引起临床医师足够的重视，以降低卒中再发风险。
