摘　　要：用彩超对６３例妊娠和１２例非妊娠妇女肾内小动脉（Ｉｎｒａ）和脐动脉（Ｕａ）内径、平均血流速度，分别进行检测，并计算出它们的血流量（ＢＦＶ）。结果：（１）孕妇Ｉｎｒａ内径和ＢＦＶ较非孕妇内径宽、血流量多；正常妊娠组内径和ＢＦＶ较妊高征组内径宽、血流量多；妊高征组ＢＦＶ与尿蛋白量呈负相关；（２）Ｕａ内径和ＢＦＶ，在正常妊娠组和妊高征组，分别呈正相关；在重度妊高征时，新生儿出生体重与ＢＦＶｕａ呈正相关；（３）ＢＦＶｉｎｒａ／ＢＦＶｕａ值，在重度妊高征该值上升。说明用彩超检测ＢＦＶｉｎｒａ和ＢＦＶｕａ及它们间比值变化，对高危妊娠预后及预测围产儿结局有一定价值。Seventyfive women were diveded into four groups: (1) Normotensive pregnant women (N=25). (2) Patients with pregnancy-induced-hypertension (PIN, N=32). (3) chronic hypertensive pregnant women (N=6). and (4 ) Nonpregnant women (N=12). Vessel diameter, mean blood flow velocity of intrarenal small artery in all women and umbilical artery were measured with pulse and color Doppler ultrasound in the third trimester of all pregnant women. Blood flow volume (BFV) was calculated. Results showed: (1) the difference of mean vessel diameter and mean BFV in intrarenal small artery (BFV inra) was significant in normotensive pregnant women and nonpregnant women and the same findings were found in normotensive pregnant women and PIH patients. BFV was negatively correlated to the amount of proteinuria. (2) mean vessel diameter of the umbilical artery (BFV ua) was positively correlated to the mean BFV in normal group and mild and modorate PIH group. Neonatal birth-weight and BFV showed significant positive correlation in the severe PLH group. (3 ) BFV inra/BFV ua ratio was risen severe PIH. Our findings may be valuable in the evaluation of prognosis in women with high-risk pregnancy and in the anticipation of outcome in perinatal child.
