During a 9-month period the carotid arteries of 2420 consecutive patients were investigated by conventional Doppler and duplex ultrasonography as well as by colour-coded duplex sonography. Of 186 internal carotid arteries showing a diameter reduction at the bifurcation level of 95% or more by conventional techniques, 131 underwent X-ray angiography which revealed a subtotal stenosis in 25 and an occlusion in 106 cases. Using a total of ten criteria for describing the colour-coded duplex findings, the "distal colour filling", a combination of three single criteria, could be found in all subtotal stenoses and none of the occlusions. "Distal colour filling" was diagnosed if a colour signal was present for a length of at least 1.5 cm directly behind an assumed stenosis comprising the whole area between the vessel walls. Our results suggest that non-invasive colour-coded duplex sonography is superior to conventional Doppler and duplex techniques and comparable to invasive X-ray angiography in differentiating extracranial subtotal carotid artery stenoses from occlusions.
在9个月的时间里，对2420例连续患者的颈动脉进行了传统多普勒和双功超声检查以及彩色编码双功超声检查。在186条通过传统技术显示在分叉处直径缩小95%或更多的颈内动脉中，131条接受了X线血管造影，其中25例显示次全狭窄，106例显示闭塞。使用总共十条标准来描述彩色编码双功超声检查结果，“远端彩色充盈”（由三个单一标准组合而成）在所有次全狭窄中均可发现，而在所有闭塞中均未发现。如果在假定狭窄（包括血管壁之间的整个区域）后方至少1.5厘米的长度内存在彩色信号，则诊断为“远端彩色充盈”。我们的结果表明，在区分颅外颈总动脉次全狭窄与闭塞方面，非侵入性彩色编码双功超声检查优于传统多普勒和双功技术，且与侵入性X线血管造影相当。
