Abstract
The impact of migraines as a risk factor for cervicocerebral artery dissection was retrospectively investigated in patients who had a cervicocerebral artery dissection. We first evaluated the patients’ medical records and history of migraine and then calculated the proportion of patients with migraine as well as the relevant vascular risk factors. The prevalence of migraine with respect to the location of the cervicocerebral artery dissection was also identified. Sixty-two patients (37 men, 25 women) had both a cerebral artery dissection and a record of migraine. Among them, 93.5% presented with an isolated headache, and 6.5% presented with a related stroke. Regarding the locations of the artery dissection, 56 (90.3%) were in the intracranial vertebral artery (VA), three (4.8%) were in the internal carotid artery, and one case each (1.6%) was in an anterior cerebral artery, basilar artery (BA), and both the VA and BA. Among the patients with VA dissection, 42 (73.7%) presented with migraines. Among the four patients with dissection of an artery of anterior circulation, only one (25%) had a migraine history. The frequency of migraines tended to be higher in the patients with VA dissection compared to those with a dissection of arteries of anterior circulation. These data suggest that (i) migraine is a potent risk factor for cerebral artery dissection, especially intracranial VA dissection, and (ii) the intracranial VA may be more susceptible to dissection compared to arteries of anterior circulation.
