| Objective To investigate prenatal sonographic features of 12 conjoined twins. Methods A retrospective analysis was made in 12 conjoined twins diagnosed with prenatal ultrasonography. All the cases were confirmed by following-up or autopsy. Results In 12 conjoined twins, 10 were symmetry conjoined twins, including 5 thorax-omphalopagus, 3 cephalopagus, 1 parapagus and 1 pyopagus; the other 2 cases were asymmetry conjoined twins-parasitus. Seven cases were female and 2 were male, the rest 3 remained unclear of sexuality. Eight cases had abnormal number umbilical vessels. The ultrasonographic characteristics were similar in thorax-omphalopagus, but various in cephalopagus and special in 2 parasitus. Conclusion Prenatal ultrasonography can provide important information for diagnosis of conjoined twins.Ultrasonographic characteristics of different conjoined twins are useful to improve the diagnosis level. |
