【摘要】：目的:超声检测不同孕期的重型α-地中海贫血胎儿(重型α-地贫)的右心室舒张末期和收缩末期面积之差与舒张末期面积之比(RVFAC),研究重型α-地贫胎儿与正常胎儿右心室RVFAC的改变关系。方法:研究组:通过回顾性分析经我院确诊为不同孕期的70例重型α-地贫所测之RVFAC数据;对照组:分析同孕期(70例)正常胎儿RVFAC数据。分析重型α-地贫胎儿与正常胎儿RVFAC改变关系并进行对照分析。结果:所有重型α-地贫RVFAC随着孕龄的增加而递减。重型α-地贫组胎儿RVFAC低于对照组胎儿,差异有统计学意义(P0.05)。结论:重型α-地中海贫血胎儿RVFAC可作为评估重型α-地贫胎儿一项重要指标。彩色多普勒超声对重型α-地中海贫血胎儿RVFAC的研究对提高重型α-地贫胎儿的检出率有一定的意义。
[Abstract]:Objective: to study the ratio of right ventricular end-diastolic and end-systolic area to end-diastolic area of severe 伪 -thalassemia fetus (severe 伪 -thalassemia) in different pregnancy and to study the relationship between severe 伪 -thalassemia fetus and normal fetus. Methods: the RVFAC data of 70 cases of severe 伪 -thalassemia diagnosed in our hospital during different pregnancy were analyzed retrospectively. Control group: the RVFAC data of 70 normal fetuses with the same pregnancy were analyzed. The changes of RVFAC in severe 伪 -thalassemia fetus and normal fetus were analyzed and compared. Results: all severe 伪 -thalassemia RVFAC decreased with the increase of gestational age. The RVFAC of 伪 -thalassemia group was lower than that of control group. Conclusion: fetal RVFAC of severe 伪 -thalassemia can be used as an important index for the evaluation of severe 伪 -thalassemia fetus. The study of Color Doppler Ultrasound on Fetal RVFAC of severe 伪 -thalassemia can improve the level of severe 伪 -thalassemia Fetal RVFAC. The detection rate of thalassemia fetus has certain significance.
