BACKGROUND
Transcranial Doppler ultrasound (TCD) has been used as a confirmatory test for the diagnosis of brain death (BD), but may be inaccurate in patients with a skull defect or extraventricular drain (EVD).
METHODS AND RESULTS
We report three cases of patients with a skull defect or EVD in whom TCD supported a diagnosis of BD but in which the clinical examination later refuted the diagnosis.
CONCLUSION
We caution against the use of TCD to confirm the diagnosis of BD in the presence of a skull defect or EVD.
背景
经颅多普勒超声（TCD）已被用作脑死亡（BD）诊断的确认性检查，但在有颅骨缺损或脑室外引流（EVD）的患者中可能不准确。
方法与结果
我们报告了3例有颅骨缺损或EVD的患者，TCD支持BD的诊断，但后来临床检查推翻了该诊断。
结论
我们提醒，在存在颅骨缺损或EVD的情况下，不要使用TCD来确认BD的诊断。
