The blood flows in the common, internal, and external carotid arteries were determined as a percentage of the cardiac output by video dilution technique in 20 normal subjects during routine angiography. Nine women and 11 men, ages 19-63 years, displayed a mean flow in the common carotid of 8.5% (SD +/- 0.9%; n = 40); internal carotid, 5.3% (SD +/- 1.0%; n = 24); and external carotid, 3.2% (SD +/- 0.4%; n = 24). Relative flow is calculated by a modification of the Stewart-Hamilton principle. The technique is fast, simple, highly accurate, and avoids the errors connected with previous videodensitometric mean transit time techniques. The method can be used in routine angiography without prolonging the catheterization procedure or adding to the patient's risk or cost.
在常规血管造影期间，采用视频稀释技术对20名正常受试者的颈总动脉、颈内动脉和颈外动脉血流进行测定，结果以心输出量的百分比表示。9名女性和11名男性，年龄19 - 63岁，颈总动脉平均血流量为8.5%（标准差±0.9%；n = 40）；颈内动脉为5.3%（标准差±1.0%；n = 24）；颈外动脉为3.2%（标准差±0.4%；n = 24）。相对血流量通过对斯图尔特 - 汉密尔顿原理进行修正来计算。该技术快速、简单、高度准确，并且避免了与先前视频密度测定平均通过时间技术相关的误差。该方法可用于常规血管造影，而不会延长导管插入术过程，也不会增加患者的风险或费用。
