Sažetak
The purpose of this study was to determine the role of vertebral artery (VA) hyoplasia in the pathogenesis of migraine. We studied the extracranial part of VA in 59 migraine patients (17 with and 42 without aura) using color Doppler. In migraine with aura, 29 percent of patients had hypoplastic VA, and in migraine without aura 7 percent. In migraine with aura, mean diameter of the right VA was 2.7 +/- 0.7 mm, and of the left 3.3 +/- 0.7 mm; in migraine without aura mean diameter was 3.1 +/-0.5 mm on the right, and 3.3 +/-0.6 on the left. In migraine with aura, mean mean systolic blood flow velocity was 55 +/-16 cm/s on the right, 60+/-17 cm/s on the left, in migraine without aura 57+/-18 cm/s on the right, 57+/-18 on the left. We observed higher frequency of hypoplastic VA in migraine with aura, suggesting that hypoplasia of VA may be an additional factor which can lead to hyoperfusion in the posterior circulation during the aura phase.
