Twin-Reversed Arterial Perfusion Sequence/Syndrome (TRAP): An Insight into the Ultrasonographic Features for Prenatal Diagnosis and Review of Literature

摘要

We present two case reports of twin reversed arterial perfusion sequence- a rare type of twin-twin transfusion syndrome wherein there is abnormal development of one fetus which derives its blood supply from the normal fetus.
