ABSTRACT
Objective To study the clinical significance of the method of three perpendicular planes plus special planes in diagnosing fetal cleft lip /palate by prenatal ultrasound .Methods The approach of three perpendicular planes and special planes were used in diagnosing 110 cases of cleft lip/palate.The sonogram features in each section were analyzed and the outcomes were recorded during follow-up.Results On prenatal ultrsound ,110 cases were examined with three perpendicular planes method .The coronary section could be displayed at 100%cases (110 cases), sagittal section 76.4%cases (84 cases),transverse section 96.4%cases (106 cases) and parasagittal section 25.5%cases (28 cases).With special planes method,74 cases were examined .The section through pyriform aperture could be displayed in 47 cases,in 45 cases on the section through the lower lip/lower jaw/submandibular triangle ,and in 16 cases on the section through the cheek.Combining the three perpendicular planes and special planes methods ,94.5%(104/110) cases could be diagnosed definitely.Six cases (5.5%,6/110) were missed because of fetal position or oligoamnios . Conclusions The method of three perpendicular planes plus special planes is effective in prenatal ultrasound diagnosing cleft lip/palate,which is of great help in improving prenatal diagnostic accuracy of fetal cleft lip/palate.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the perinatal management and outcome of different types of fetal arrhythmia.</p><p><b>METHODS</b>A retrospective analysis was conducted among the fetuses with arrhythmia identified by M-mode and pulsed Doppler echocardiography in a single institution between October 2003 and December 2010.</p><p><b>RESULTS</b>A total of 130 fetuses were found to have fetal arrhythmia. The most common arrhythmia during pregnancy was extrasystole (n=59), followed by bradycardia (n=23), tachycardia (n=16), atrial flutter (AF, n=3), atrioventricular block (AVB, n=12) and other arrhythmia (n=17). The overall incidence of cardiac anomalies (commonly fetal bradycardia) was 9.2% in these cases. The prognosis of arrhythmia differed significantly between cases of different classifications. The type of fetal arrhythmia (P=0.024), presence of congenital heart defect (CHD, P=0.000) and fetal hydrops (P=0.008) were significant risk factors associated with termination of pregnancy.</p><p><b>CONCLUSION</b>Fetal arrhythmias without CHD or hydrops under close monitoring often have good clinical outcome, while fetal bradycardia is associated with a high mortality rate. CHD and the presence of fetal hydrops are significant risk factors for pregnancy termination.</p>

<p><b>OBJECTIVE</b>To study the value of prenatal ultrasound in the diagnosis of fetal malformations.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 993 cases of neonates and induced babies with malformations who were labored in our hospital from January 1999 to October 2006.</p><p><b>RESULTS</b>The incidence rate of fetal malformation was 22.5 per thousand in our study group. The detection rate of prenatal ultrasound was 79.02% (1 062/1 344), among which the detection rate of the severe malformations (87.58%, 860/982) were significantly higher than that of the minor malformations (55.80%, 202/362) (P < 0.005). The false negative rate was high for the extremity malformations (39.46%) and facial malformations (31.91%), especially the acrosclerodermas, simple cleft palates, and ear deformities.</p><p><b>CONCLUSION</b>Prenatal ultrasound is sensitive for fetal severe malformations, while the detection rate is low for fetal minor malformations.</p>
