Background: Data on the difference between migraine and intracranial arterial stenosis (ICAS) based on transcranial Doppler (TCD) findings are limited. This study aimed to investigate the differences in the features of TCD abnormality between migraine and ICAS.
Methods: Forty-one migraine patients with normal angiography and 35 ICAS patients were retrospectively recruited and assigned to two respective groups. The TCD variables from the arteries with Doppler abnormality were compared between the two groups using an independent t-test or chi-square test.
Results: For all analyzed intracranial arteries, turbulent flow was more frequent in the ICAS group. The prevalence of side-to-side difference >30% was significantly higher in the middle cerebral artery (MCA) and vertebral artery (VA) of ICAS patients. Focal increase in mean flow velocity (mFV) was more frequently observed in the MCA of ICAS patients. The mFV was markedly increased with a wide range of distribution in the MCA, VA, and basilar artery of ICAS patients. Meanwhile, the mFV in migraine patients was only modestly increased. The absence of turbulence flow had a sensitivity of 92.5% and a specificity of 88.9%, while mFV <120 cm/s had a sensitivity of 74.5% and a specificity of 100% to diagnose migraine.
Conclusion: Turbulent flow with a marked elevation, focal variation, and asymmetry of mFV favor the diagnosis of ICAS, while the relatively uniform and modest increase in mFV favor the diagnosis of migraine.
