Twin 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-...
متن کاملTwin Reversed Arterial Perfusion Sequence / Sequence Acephalus Acardiac Fetus
Twin reverse arterial perfusion (TRAP) sequence occurs only in a setting of a monochorionic gestation and complicates approximately 1% of monochorionic twin gestation. In the TRAP sequence the acardiac / acephalic twin receives all of its blood supply from the normal “pump” twin.
متن کاملDiagnostic dilemma in twin-reversed arterial perfusion sequence.
The twin-reversed arterial perfusion (TRAP) sequence is a rare complication of twin pregnancies. The anatomically normal twin is termed the pump twin; the recipient twin is malformed and is known as acardiac twin. It functions as a parasite to the pump twin and receives retrograde blood flow of poorly oxygenated blood from the pump twin via the abdominal aorta, resulting in a wide spectrum of m...
متن کاملThe TRAP (twin reversed arterial perfusion) sequence - case presentation.
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...
