ABSTRACT
Objective To investigate the clinical manifestations, angiographic features and clinical significance of kinking of extracranial internal carotid artery (ICA). Methods The clinical and radiological data of 21 patients with kinking of extracranial ICA were retrospectively reviewed in our hospital from April 2003 to July 2007. Fisher exact test was performed. Results Of the 21 patients, 7 hod no clinical symptoms, the other 14 showed manifestations of cerebral iachemia with varying degree. One of the characteristic clinical manifestations that neck rotation or specific positions of head and neck might induce the occurrence of clinical symptoms was found in 5 cases. The whole-brain coverage DSA accurately showed the location of kinking of extracranial ICA and the degree of vascular stenosis. In patients with α < 66%, 80% > α≥ 66% and α≥ 80%, clinical symptoms were found in 3 out of 5,7 out of 10 and 4 out of 6 patients, respectively. Fisher exact test revealed that the positive rates of clinical symptoms in three groups had no significant difference (P > 0. 05). Conclusion Kinking of extracranial ICA is a frequent vascular morphologic variation, and it is also a kind of potential disease. The whole-brain coverage DSA is a relatively reliable method to detect this variation.
