The correlation between the increase in velocity of blood flow in both the internal carotid and vertebral arteries during a carotid compression and the cerebrovascular resistance (CVR) was investigated in 11 patients with chronic ischemic cerebrovascular disease and 4 without organic brain lesions. The velocity of blood flow was measured by an ultrasonic Doppler flowmeter. CVR was calculated from cerebral blood flow and arterial blood pressure. There was no correlation between the increased velocity of blood flow in the internal carotid and vertebral arteries and CVR. The increased velocity of blood flow in patients with low CVR was, however, significantly higher than that of patients with high CVR. The investigation of cross-circulation by ultrasonic Doppler flowmetry is a useful non-invasive method for the detection of changes in cerebral vascular resistance.
对11例慢性缺血性脑血管病患者和4例无器质性脑损伤患者，研究了颈动脉压迫时颈内动脉和椎动脉血流速度增加与脑血管阻力（CVR）之间的相关性。采用超声多普勒流量计测量血流速度。根据脑血流量和动脉血压计算CVR。颈内动脉和椎动脉血流速度增加与CVR之间无相关性。然而，CVR低的患者血流速度增加明显高于CVR高的患者。用超声多普勒血流仪研究交叉循环是检测脑血管阻力变化的一种有用的非侵入性方法。
