A 66-year-old woman had an asymptomatic bruit over the right carotid bifurcation. Carotid Doppler and real-time ultrasound studies demonstrated an isolated 50 to 75% stenosis of the right external carotid artery. We devised a simple maneuver to determine which artery, internal or external carotid, caused the bruit.
一名66岁女性右侧颈动脉分叉处有无症状杂音。颈动脉多普勒和实时超声检查显示右侧颈外动脉有孤立的50%至75%狭窄。我们设计了一种简单的手法来确定是哪条动脉，即颈内动脉还是颈外动脉，导致了该杂音。
