The authors describe a child presenting with Horner's syndrome after the repeated application of birthing forceps to the head and neck during vaginal delivery. Magnetic resonance imaging and angiography confirmed that the proximal right internal carotid artery (ICA) showed injury caused by dissection. Carotid duplex and transcranial ultrasonography provided supporting evidence of distal right ICA occlusion with the development of intracranial collaterals. The authors interpret these findings to indicate that the child suffered a traumatic dissection of the distal right ICA to mimic "congenital" Horner's syndrome (CHS). In a review of English medical literature published since 1972, the authors found 70 cases of CHS, none of which was attributed to carotid dissection. This case demonstrates that carotid dissection is an underreported cause of CHS.
作者描述了一名儿童，在阴道分娩过程中头部和颈部反复使用产钳后出现霍纳综合征。磁共振成像和血管造影证实，右侧颈内动脉（ICA）近端显示有夹层引起的损伤。颈动脉双功超声和经颅超声检查提供了右侧ICA远端闭塞并伴有颅内侧支循环形成的支持性证据。作者解释这些发现表明，该儿童右侧ICA远端发生创伤性夹层，从而模拟了“先天性”霍纳综合征（CHS）。在回顾1972年以来发表的英文医学文献时，作者发现了70例CHS病例，其中无一例归因于颈动脉夹层。该病例表明，颈动脉夹层是CHS一个未被充分报道的病因。
