Abstract:
Objective To investigate the relation between anormalities of fetal abdominal great vessels and heterotaxy, the clinical significance of screening fetal heterotaxy by the abnormalities of fetal abdominal great vessels. Methods 6532 fetuses from our hospital were scanned and the fetuses with abdominal great vessels abnormalities were included. Parameters of fetal growth, abdominal great vessels and anatomical survey were detected. Results Forty-five cases (0.7%) of fetal abdominal great vessels abnormalities were detected prenatally. Forty-two cases were confirmed postnatally, including 35 cases of heterotaxy syndrome and 7 cases of situs inversus totalis and 3 cases missed. The incidences of the abnormal fetus,heterotaxy syndrome and situs inversus totalis of the fetuses with abnormal abdominal great vessels were higher than that of the fetuses with normal abdominal great vessels, the differences were statistically significant( P＜ 0.001). The incidence of both type Ⅰ and type Ⅱ of the heterotaxy syndrome were significantly higher than that of type Ⅳ (P＜0.001). There was a high incidence of left isomerism in abnormal type Ⅰ and of right isomerism in abnormal type Ⅱ , the differences were statistically significant (P＜ 0.001). Conclusions Abnormal great vessels abnormalities have strong relations to heterotaxy and situs inversus which can be used as effective and simple indicator in screening heterotaxy syndrome.
