Transcranial Doppler sonography (TCD) was performed in a case of migraine with aura during the different phases of the attack. In the prodromic period our patient showed a slight central deficit of the seventh right cranial nerve and hypesthesia in her right arm. TCD indicated a remarkable decrease of the mean flow velocity (MFV) of the left middle cerebral artery (MCA). During the headache phase and when the signs and symptoms subsided, TCD showed an increase in MFV of both middle cerebral arteries with normal symmetry. An electroencephalogram (EEG) demonstrated a left temporal disorder. A month later a cranial CT scan, an EEG, and TCD were normal. In our opinion all these findings suggest a focal reduction in cerebral blood flow in the prodromic phase.
对一名有先兆偏头痛患者在发作的不同阶段进行了经颅多普勒超声检查（TCD）。在前驱期，我们的患者表现出右侧第七颅神经轻度中枢性缺损以及右臂感觉减退。TCD显示左侧大脑中动脉（MCA）平均血流速度（MFV）显著降低。在头痛期以及体征和症状消退时，TCD显示双侧大脑中动脉MFV增加且对称性正常。脑电图（EEG）显示左侧颞叶异常。一个月后，头颅CT扫描、EEG和TCD均正常。我们认为所有这些发现提示在前驱期脑血流量有局灶性减少。
