Ultrasonography of hydramnion complicated by fetal malformation during pregnancy

Objective：To evaluate the type features and influencing factors of hydramnion complicated by fetal malforma- tion during pregnancy. Methods.. Ultrasound imaging features of 63 fetuses diagnosed of hydramnion accompanied by fetal malformation during conventional ultrasound examinations were retrospectively analyzed. All fetal malformations were classified and analyzed. Results：Of these 63 cases of hydramnion complicated by fetal malformation, 16 cases were com- bined with fetal malformation in central nervous system （25.4 %）, 9 with fetal malformation in multi-structure （14.3 % ）, 9 with fetal malformation in urinary system （14.3%）, 7 with fetal malformation in digestive system （11.1%）, 7 with fe- tal malformation in thorax （11.1%）, 5 with fetal malformation in masillofacial region （7.9 % ）, 3 with fetal malformation in skeleton （4.8%）, 3 with fetal hydrops （7.9%）, 2 with fetal teratoma in sacrococcygeal region （3.2%）, 1 with twin- to-twin transfusion syndrome （1.6%）, and 1 with single umbilical artery （1.6%）. Conclusion： Ultrasound examination is accurate and reliable in diagnosis of hydramnion accompanied by fetal malformation. The common kinds of fetal malforma- tion are central nervous system malformation, ulti-structure malformation, urinary system malformation, digestive system malformation, and thoracic malformation.
