Two hundred and fifty-four patients who underwent carotid angiography for common neurological and neurosurgical disorders were reviewed. The incidence and angiographic features of loops, coils, kinks and atheroma are analysed. Loops are common (34%), coils and kinks are not uncommon (7 and 6.6% respectively). The aetiology of these conditions and their clinical importance are discussed. Loops and coils have a developmental basis and do not by themselves cause cerebrovascular ischaemic attacks or influence the patchy development or atheroma. Kinks are acquired and are frequently seen in association with loops but their cause has not been established.
对254例因常见神经科和神经外科疾病接受颈动脉血管造影的患者进行了回顾性研究。分析了血管袢、盘曲、扭结和动脉粥样硬化的发生率及血管造影特征。血管袢很常见（34%），盘曲和扭结也并不少见（分别为7%和6.6%）。讨论了这些情况的病因及其临床重要性。血管袢和盘曲有发育基础，本身不会引起脑血管缺血性发作，也不影响斑块形成或动脉粥样硬化。扭结是后天形成的，常与血管袢同时出现，但其病因尚未明确。
