ABSTRACT
Objective To explore the correlation between the cardiovascular ultrasound results and pathological findings of heterotaxia syndrome ,analyze the cause of the difference ,and improve the prenatal cardiovascular diagnostic accuracy of heterotaxia syndrome by ultrasound . Methods According to fetal autopsy or vessel casting , the ultrasound results of 37 fetuses with heterotaxia syndrome were retrospectively analyzed . The cardiovascular misinterpretations of ultrasound were summarized in the venous-atrialsegment,atrial-ventricular segment andventricular-arterial segment.Results ①Thirty fetuses underwent autopsy and seven fetuses vessel casting were included ,there were 10 fetuses with left atrial isomerism and 27 fetuses with right atrial isomerism .Only one left isomerism was misdiagnosed and the diagnostic accuracy of atrial isomerism by ultrasound was 97 .3％ . ② Thirty-seven fetuses with heterotaxia syndrome included 206 cardiovascular malformations . Twenty-seven misinterpretations of ultrasound were found and the rate of cardiovascular misinterpretations was 13 .1％ . ③ The cardiovascular misinterpretations of left atrial isomerism involved 1 secondary atrial septal defect in the atrial-ventricular segment and 1 aortic atresia ,2 anomalous position of arterial duct in the ventricular-arterial segment . ④The cardiovascular misinterpretations of right atrial isomerism in the venous-atrial segment included 4 common pulmonary vein atresia , 3 anomalous hepatic venous connection , 3 total abnormal pulmonary venous drainage , 2 persistent left superior vena cava and 2 abnormal inferior cava venous drainage . The cardiovascular misinterpretations of right atrial isomerism in the atrial-ventricular segment contained 2 secondary atrial septal defect ,1 unroofed coronary sinus and 1 partial atrioventricular septal defect . The cardiovascular misinterpretations of right atrial isomerism in the ventricular-arterial segment involved 3 double-outlet right ventricle ,1 truncus arteriosus and 1 anomalous position of arterial duct . Conclusions The correspondence between ultrasound results and pathological findings about cardiovascular malformations of heterotaxia syndrome is high . The most common cardiovascular misinterpretations of left atrial isomerism involve the ventricular-arterial segment . And the most common cardiovascular misinterpretations of right atrial isomerism involve the venous-atrial segment .
ABSTRACT
Objective To analyze the echocardiographic findings , associated anomalies and chromosomal characteristics in fetuses with pulmonary atresia with ventricular septal defect ( PA/VSD ) . Methods T he echocardiographic data and follow‐up materials were retrospectively reviewed in 30 256 fetuses from December 2012 to M arch 2018 in the consultation center of fetal heart disease in maternal‐fetal medicine in Anzhen hospital . Of all the fetuses ,59 cases ( 0 .19% ) had PA/VSD . T he echocardiographic findings ,associated anomalies and chromosomal characteristics were retrospectively analyzed in all the 59 fetuses with PA/VSD . Based on w hether the presence of the native pulmonary arteries and the major aortopulmonary collateral arteries ( M APCAs) or not ,the PA‐VSD was classified into type A ,type B ,and type C . Results A large ventricular defect was demonstrated in five‐chamber view with 61 .7% of the mean ratio of the aortic overriding . O ther fetal echocardiographic features of all the 59 fetuses with PA/VSD included :the right aortic arch ( n ＝19 ) ,reversal flow in the ductus arteriosus ( n ＝40 ) ,M APCAs ( n ＝24) . T he classification of the PA/VSD included :type A ( n ＝35) ,type B ( n ＝5) and type C ( n ＝19) . Associated anomalies :persistent left superior vena cava ( n ＝ 13 ) ,anomalous pulmonary vein connection ( n＝5 ) ,complete atrioventricular septal defect ( n ＝ 5 ) ; single umbilical artery ( n ＝ 3 ) ,right atrial isomerism ( n ＝3) . Of all the 30 cases performed chromosomal test ,3 cases had aneuploidy and 7 cases had microdeletion of chromosome . Conclusions The fetal echocardiographic findings of the PA/VSD are characteristic . For prenatal diagnosis of PA/VSD ,the type of PA/VSD should be defined and chromosomal test should be performed ,w hich can be helpful for prenatal consulting .
ABSTRACT
Objective To explore effect of vidarabine monophosphate combined with astragalus injection on serum cardiac troponin I ( cTnI), interleukin 1β(IL-1β), interleukin-10 (IL-10) and tumor necrosis factor-α(TNF-α) in children with hand-foot-and-mouth disease.Methods 60 cases with hand-foot-and-mouth disease from March 2013 to March 2015 in the hospital were selected and divided into two groups treated by different therapy, 30 cases in each group.The control group received conventional treatment + ribavirin injection, and experimental group received vidarabine monophosphate combined with astragalus injection on the basis of conventional treatment, one time per day.All patients were treated for a course of 7 days.The serum cTnI,IL-1β,IL-10 and TNF-αlevels were compared before and after treatment.Results After treatment, the serum cTnI, IL-1β, IL-10 and TNF-αlevels in two groups decreased than those of pre-treatment (P<0.05), the above indicators of experimental group were lower than those of control group (P<0.05).Conclusion The combination of vidarabine monophosphate and astragalus injection could significantly decrease serum cTnI, IL-1β, IL-10 and TNF-αlevels in children with hand-foot-and-mouth disease.
