twin reversed arterial perfusion (trap) sequence; characteristic gray-scale and doppler ultrasonography findings
twin reversed arterial perfusion (trap) sequence is a syndrome with poor prognosis, seen only in monochorionic monozygotic twin pregnancies. the incidence is one in 35.000 births and one in 100 monozygotic twin pregnancies. it is characterized with a recipient fetus exhibiting lethal anomalies including acardia and a pump fetus. mortality is usually due to heart failure or premature labor cause...

متن کاملTwin Reversed Arterial Perfusion (trap) Sequence: Biology and Management
In the usual setting, blood from the placenta enters the fetal circulation through the umbilical veins and exits via the umbilical artery. Very rarely (1% of MC twins or 1:35,000 births), retrograde or reversed arterial perfusion takes place, from the placenta through the umbilical artery of one of the twins, and the twin with the reversed flow receives all of its blood supply from a normal co-...

We present a particular case of TRAP (twin reversed arterial perfusion) syndrome, which has a very rarely association of the simultaneous existence of a rudimentary malformed heart and brain, and also other malformations like abdominal wall abnormality, absent bladder with present kidneys, and absence of the lungs, which appear only in a few cases on the receptor twin from this sequence, malfor...
