We studied the value of Pourcelot's index of resistance in the anterior cerebral arteries (RI-ACA) and basilar artery (RI-BA) in 69 measurements of term infants on days 1, 5, 10, 15, 20, 30 and 60. The mean value of RI-ACA (0.723 +/- 0.038, +/- SD) was significantly lower than that of RI-BA (0.750 +/- 0.041) (p less than 0.001). RI-ACA values were higher than RI-BAs in only five measurements (7.2%). The values of RI-ACA and RI-BA decreased from the first day to the fifth day of life. They increased continuously and showed their highest values on the day 15. After the 15th day, they decreased mildly again. The values of RI ratio (= RI-ACA/RI-BA) were stable (0.96-0.97).
我们对69例足月儿在出生第1天、第5天、第10天、第15天、第20天、第30天和第60天进行了大脑前动脉（RI-ACA）和基底动脉（RI-BA）的普尔塞洛特阻力指数测量研究。RI-ACA的平均值（0.723±0.038，±标准差）显著低于RI-BA的平均值（0.750±0.041）（p<0.001）。仅在5次测量（7.2%）中RI-ACA值高于RI-BA值。RI-ACA和RI-BA的值在出生后第1天到第5天下降。它们持续上升，并在第15天达到最高值。在第15天之后，它们又再次轻微下降。RI比值（=RI-ACA/RI-BA）稳定（0.96 - 0.97）。
