Ultrasonographic prenatal diagnosis of conjoined thoracopagus twins: a case report.

A case of prenatal diagnosed thoracopagus conjoined twins is presented. In thoracopagus twins the cardiovascular system mainly determines the options for separation and survival. Therefore prenatal investigation of this organ system is indispensable. Ultrasound level-2 examination predicted the impossibility of separation and fully matched the autopsy findings. In conclusion, ultrasound examination appears to be an important tool to enable planning of the optimal delivery approach.
