【摘要】：目的探讨胎儿心功能不全的超声诊断依据和可行性。方法应用彩色多普勒超声对心功能不全组和对照组心脏收缩功能指标和子宫-胎盘循环-胎儿循环血流参数进行对比分析。结果对照组胎儿左、右心室短轴缩短率(Fs)、射血分数(EF)比较差异无统计学意义(P0.05);心功能不全组胎儿右室Fs及EF均低于左室,差异有统计学意义(P0.05)。心功能不全组心胸面积比增大、异常脐静脉搏动征、三尖瓣反流、脐动脉(UA)及大脑中动脉(MCA)搏动指数(PI)、阻力指数(RI)、收缩期/舒张期血流速度比(S/D)与对照组比较差异有统计学意义(P0.05);下腔静脉逆向血流速度增加及静脉导管a波反向,两组比较差异无统计学意义(P0.05)。结论心功能不全的胎儿右室Fs及EF均低于左室,心胸面积比增大、三尖瓣反流、异常脐静脉搏动征、UA阻力增大、MCA阻力减小是胎儿心功能不全的可靠依据。
[Abstract]:Objective to investigate the ultrasonic diagnostic basis and feasibility of fetal cardiac insufficiency. Methods the indexes of cardiac systolic function and the blood flow parameters of uterine placenta circulation and fetal circulation in patients with cardiac insufficiency and control group were analyzed by color Doppler ultrasound. Results in the control group, there was no significant difference in the shortening rate of left and right ventricular short axis (FsN) and ejection fraction (EFF), but in the group of cardiac insufficiency, the FS and EF of the right ventricle were lower than those of the left ventricle, and the difference was statistically significant (P 0.05). In patients with cardiac insufficiency, cardiothoracic area ratio increased, abnormal umbilical vein pulsatile sign, tricuspid regurgitation, The pulsatile index (Pi), resistance index (RI), systolic / diastolic velocity ratio (S / D) of umbilical artery (UAA) and middle cerebral artery (MCA) were significantly different from those of the control group (P 0.05), the reverse flow velocity of inferior vena cava was increased and the a wave of the catheter was reversed. There was no significant difference between the two groups (P 0.05). Conclusion the FS and EF of fetal right ventricle with cardiac insufficiency are lower than that of left ventricle, the ratio of heart to chest area increases, tricuspid regurgitation and UA resistance of abnormal umbilical vein pulsatility increase. The decrease of MCA resistance is the reliable basis for fetal cardiac insufficiency.
