Twin Reversed Arterial Perfusion Sequence / Sequence Acephalus Acardiac Fetus
نویسندگان
چکیده
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 کاملA case of TRAP sequence with immense acardiac twin.
Twin-reversed arterial perfusion sequence is a rare complication of monochorionic twin pregnancy in which an anomalous acardiac fetus is hemodynamically dependent on its structurally normal "pump" twin. Early diagnosis is essential for improving perinatal prognosis for the normal twin. In this case report we present a case of TRAP sequence with immense acardiac twin with favorable outcome, emph...
متن کاملTRAP 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 [2] (MC, twins sharing one placenta). One twin is usually structurally completely normal. The other is an abnormal mass of tissue, consisting usually of legs and a lower body, but no upper body, head or heart. Because of the absent heart, the term ?a...
