Objective: The study aims to evaluate the efficacy of radiofrequency ablation (RFA) with an internally cooled electrode for twin reversed arterial perfusion (TRAP) sequence. Methods: From April 2008 through December 2014, we retrospectively reviewed all patients who underwent RFA with an internally cooled electrode for TRAP sequence at 3 tertiary referral centers in Japan. Results: Twenty-five monochorionic diamniotic twin pregnancies underwent RFA with an internally cooled electrode for TRAP sequence at 16-27 weeks of gestation. In all cases, umbilical cord blood flow cessation in the acardiac twin was confirmed by ultrasonography with color Doppler. There were 2 cases of procedure-related complications: 1 case of unintentional septostomy and 1 case of anemia in a pump twin. Fetal demise of the pump twin occurred in 3 (12%) cases. Twenty-two (88%) of 25 pump twins were delivered alive. The median gestational age at delivery was 36 + 3 weeks (range 25 + 2-40 + 5 weeks). There were 14 cases (64%) of premature deliveries before 37 weeks and 5 (23%) before 32 weeks. Conclusion: RFA with an internally cooled electrode is a feasible and effective procedure for the treatment of TRAP sequence.

We report a case of a twin-reversed arterial perfusion (TRAP) sequence complication in monochorionic triplets, in which both normal fetuses were directly connected to the umbilical cord of the acardiac fetus, thus both acting as a pump twin. Doppler ultrasound showed a significant waveform pattern with two superposed systolic waveforms in the same vessel. After birth, placental findings confirmed the existence of two direct pump twins. The Doppler pattern described here may be of help to distinguish the existence of two pump twins in a triplet monochorionic pregnancy with TRAP.

AbstractRadiofrequency ablation (RFA) has become widely accepted as first-line management for twin reversed arterial perfusion (TRAP) sequence. Most RFA procedures have been performed using RFA needles of 14–17 gauge (G) focusing on an acardiac mass at an average age of 21 weeks of gestation (17–24 weeks). In this case report, we describe treatment of TRAP sequence using RFA with a 20 G needle focusing a feeding artery on the placental surface at gestational age of 11+6.

Abstract 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, emphasizing the importance of ultrasound imaging, follow-up and timing of delivery in this complicated pregnancy.

AbstractTRAP (Twin Reversed Arterial Perfusion) sequence is a rare malformation that occurs in monozygotic twin pregnancies. Twin weight ratio in our case was 76% (body weight of pump twin was 1800 g, acardiac twin 1370 g), but in spite of that the pump twin had a mild clinical picture with premature birth, fetal hydrops (mild pleural effusion; hypoproteinemia; on the 3rd day of life the baby was without edema and the level of his serum proteins were in referral ranges) and mild myocardial hypertrophy of left ventricle (echocardiography performed on the 28th day of life was normal).

Introduction: Twin-reversed arterial perfusion sequence is a rare complication of monochorionic pregnancies that is characterized by the presence of an acardiac mass perfused by an apparently normal pump twin. The risk of death to the pump twin has led to a range of therapeutic interventions aimed at separating their vascular connection. We report a novel application of microwave ablation for vessel coagulation in the treatment of twin-reversed arterial perfusion sequence. Material and Methods: Microwave ablation has been adopted by surgical subspecialties as a superior energy source for vessel and tissue ablation as it creates heat without a circuit and has less thermal spread. We describe the use of a 2.45-GHz microwave system using a 1.8-mm antenna to coagulate the intra-abdominal portion of umbilical vessels of the acardiac mass. Results: We report 6 cases of twin-reversed arterial perfusion sequence treated by microwave ablation. All patients were treated with microwave ablation with successful coagulation of intra-abdominal umbilical cord vessels of the acardiac mass with cessation of flow. Discussion: Microwave ablation is an excellent energy source for vessel coagulation due to its thermal properties and can be used effectively in the treatment of twin-reversed arterial perfusion sequence.
