Evaluation of blood flow velocity in unilateral headache using transcranial doppler [TCD] ultrasonography

ABSTRACT

This study aimed to evaluate blood flow velocity [FV] and pulsatility index in patients with unilateral headache. Sixty-six patients were examined during headache-free period, three patients during attack of migraine and fourteen as control healthy volunteers who were migraine - free individuals and without cerebrovascular diseases. Mean flow velocity and pulsatility index was measured in the middle cerebral artery using transcranial Doppler. The sixty-six patients were divided into three subgroups as followed; 34 patients as non-dominant sided headache, 27 patients as dominant-sided headache and 5-patients with definite brain lesions. The FV mean of patients with definite brain lesion significantly increased on comparison with the control group, the non-dominant sided headache and the dominant sided headache. There was no significant difference between FV mean of the side of headache and the other side [non-painful side] in patients with dominant sided headache
