Twin reversed arterial perfusion - Wikipedia
Illustration of TRAPS pregnancy. On the left, the acardiac twin. The pump twin is on the right. Selective termination of the acardiac twin can reduce the risk of death of the pump twin.. Twin reversed arterial perfusion sequence, also called TRAP sequence, TRAPS, or acardiac twinning, is a rare complication of monochorionic twin …
Twin Reversed Arterial Perfusion (TRAP) - Johns Hopkins Medicine
The twin supplying the blood is known as the "pump twin" and develops normally in the womb. However, the increased pumping of the heart puts this twin at risk for cardiac failure. The other twin — known as the "acardiac twin" — lacks a heart or has one that is not fully formed.
TRAP Sequence or Acardiac Twin
What is TRAP sequence or acardiac twin? Twin reversed arterial perfusion (TRAP) sequence or acardiac twinning is a very rare problem, occurring in approximately 1% of monochorionic twins (MC, twins sharing one placenta). One twin is usually structurally completely normal.
双胎反向动脉灌注(TRAP)序列征 - UpToDate
引言. 双胎反向动脉灌注 (twin reversed arterial perfusion, TRAP)序列征是多胎妊娠中的单绒毛膜双胎所特有的一种罕见妊娠并发症，表现为其中一胎心脏缺如或残留无功能心脏 (“无心胎”)，完全依靠另一胎 (“泵血胎”)通过异常的动脉-动脉吻合进行逆向灌注。. 无心胎 ...
Parasitic twin - Wikipedia
The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure, much like a fetus in fetu, except the acardiac twin is outside the autosite's body.
Twin Reversed Arterial Perfusion Sequence - Fetal Health Foundation
The diagnosis of acardiac twins or TRAP sequence is suggested by the presence of a monochorionic (single placenta) twin pregnancy in which one twin (the pump twin) appears structurally normal (no ultrasound findings consistent with birth defects), while the other twin (the acardiac/TRAP twin) has multiple profound birth defects (as listed in ...
TRAP (Twin Reversed Arterial Perfusion) Sequence
Twin Reversed Arterial Perfusion (TRAP) sequence, also referred to as acardia, is a rare structural and physiologic complication of monochorionic (MC) twin gestation. It is defined as a MC (single placenta) pregnancy with one structurally normal fetus and one fetus that is acardiac or has a rudimentary heart with a reversed flow direction in ...

Twin reversed arterial perfusion - Wikiwand
Twin reversed arterial perfusion sequence, also called TRAP sequence, TRAPS, or acardiac twinning, is a rare complication of monochorionic twin pregnancies. [1] It is a severe variant of twin-to-twin transfusion syndrome (TTTS). [2]
