Is vertebral artery hypoplasia more frequent inmigraine patients?

The role of vertebral artery hypoplasia in migraine was not extensively studied. Migraine with aura has a higher incidence of vertebral artery hypoplasia. Since migraine with aura is a heritable condition, we evaluated 30 families with at least one member diagnosed with hypoplastic vertebral artery. Vertebral artery hypoplasia (VAH) was defined as < 2 mm in diameter. Vertebral arteries of 97 members of 30 families were examined with CDFI (Color Doppler Flow Imaging). Hypoplasia of vertebral arteries was found in 41 patients (14 men and 26 women). Right vertebral artery hypoplasia was present in 25 patients, left in 14 patients and bilateral hypoplasia was found in 2 patients. Migraine and vertebral artery hypoplasia was present in 8 patients (in 6 families ; 7 women, 1 man) whereas migraine without vertebral artery hypoplasia was present in 13 patients (in 9 families). The prevalence of migraine in studied group was 13, 4%. In the patients with VAH group the prevalence of migraine was 19, 5% (8 out of 41 patients). Aura was present in 5 out of 8 patients with both migraine and VAH. Our preliminary results show that VAH has a higher incidence in migraine with aura.
