초록 close

단일 융모막성 쌍태 임신에서 생길 수 있는 유일한 합병 증의 초음파 소견을 조사하고 이를 부검 및 병리소견과 비 교하였다. 쌍태아 동맥 관류 역전 연쇄 (twin reversed arterial perfusion sequence), 쌍태아 색전 증후군 (twin embolization syndrome), 결합 쌍태아 (conjoined twin), 제대 꼬임 (twin cord entanglement) 등이 관찰되었다. 이들 합병증을 잘 이해하여 산전 진단의 정확도를 높이고, 태아의 예후를 예측하는데 도움이 될 것으로 사료된다.


We reviewed the sonographic features of rare complications with monochorionic twins and we correlated these features with the pathologic findings. The complications, including the twin reversed arterial perfusion sequence, the twin embolization syndrome, the conjoined twins and umbilical cord entanglement. A better understanding of these complications can aid making an accurate prenatal diagnosis and predicting the fetal outcome.
