Abstract
We are reporting a case of twin reversed arterial perfusion (TRAP) sequence occurring in a dichorionic triamniotic triplet pregnancy with successful percutaneous prenatal treatment and excellent neonatal outcome. TRAP sequence was diagnosed at 11 weeks in a spontaneous dichorionic‐triamniotic triplet. Sonographic assessment showed persistent arterial flow and development of hydrops in the acardiac twin. Percutaneous cord interstitial laser coagulation was performed, and the co‐twin subsequently developed growth restriction. The 9‐month‐old twins have a normal developmental course. This report confirms that fetal intervention is indicated in cases of TRAP sequence in which the acardiac twin presents a significant enlargement on follow‐up sonographic examinations. © 2009 Wiley Periodicals, Inc.
