A criticism of duplex scanning of the carotid vessels is that the study is limited to evaluation of the carotid bifurcations, whereas with other vascular imaging studies the vertebral vessels can also be seen. We have prospectively collected data on our ability to evaluate the vertebral vessels on all patients who are sent for carotid evaluations. We have scanned 677 patients and have identified flow in one or both vertebral arteries in nearly 90% of these patients. Therefore, we urge that evaluation of vertebral vessels be made a routine part of the standard carotid duplex ultrasound examination.
对颈动脉双功扫描的一项批评意见是，该检查仅限于评估颈动脉分叉处，而其他血管成像检查还能看到椎动脉。我们前瞻性地收集了所有接受颈动脉评估患者的椎动脉评估能力数据。我们扫描了677例患者，在近90%的这些患者中发现了一侧或双侧椎动脉内有血流信号。因此，我们敦促将椎动脉评估作为标准颈动脉双功超声检查的常规部分。
