Colour Doppler ultrasound allows simultaneous B scan and Doppler imaging and can be employed to determine the velocity of blood flow in the vasculature of the eye and orbit. We describe a case of cranial arteritis (giant cell arteritis) in which serial velocimetry recordings were obtained. At one stage in the disease process no blood flow was detectable in the orbit despite previously reliable recordings. This coincided with a deterioration of the clinical state of the patient as signified by recurrent anterior ischaemic optic neuropathy despite controlled symptomatology and erythrocyte sedimentation rate by prednisolone therapy. Subsequent increase in the immunosuppressive therapy was accompanied by a return of blood flow in the orbit. Colour Doppler ultrasound may prove to be a useful examination technique in the diagnosis and management of cranial arteritis.
彩色多普勒超声可同时进行B超扫描和多普勒成像，可用于测定眼部和眼眶血管系统中的血流速度。我们描述了一例颅动脉炎（巨细胞动脉炎）病例，在此病例中进行了连续的血流速度测量记录。在疾病过程的某一阶段，尽管之前记录可靠，但眼眶中未检测到血流。这与患者临床状态的恶化同时出现，尽管通过泼尼松龙治疗症状得到控制且红细胞沉降率正常，但仍反复出现前部缺血性视神经病变。随后免疫抑制治疗的增加伴随着眼眶血流的恢复。彩色多普勒超声可能被证明是颅动脉炎诊断和管理中的一种有用检查技术。
