Twin reversed arterial perfusion sequence (TRAP sequence) is a condition thatoccurs only in identical twins that share a placenta (monochorionic), in which one twin lackinga functioning cardiac system “acardiac monster” receives blood from the normally developingtwin called the “pump twin”. This places an enormous demand on the heart putting the pumptwin at risk for cardiac failure. Left untreated, the pump twin will die in 50 percent to 75 percentof cases. Here we present the case report of a 20 years old G2P1at 32 weeks POG with amonochorionic twin pregnancy. One of the twins was “acardiac acephalous” and the other a“pump twin” with mild hydrocephalous.

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.

Abstract Background Twin reversed arterial perfusion sequence (TRAP) is a very rare congenital anomaly. We present sonographic findings of TRAP sequence in the case of a multiparous woman with a monochorionic monoamniotic twin pregnancy who was referred to our unit for blood sugar control. Case presentation The patient had a history of co-twin demise at 13 weeks of gestation without appropriate fetal surveillance afterwards. We found a monochorionic placentation with a normal appearing pump twin, an abnormal appearing co-twin without obvious cardiac activity and reversed arterial flow toward instead of away from the anomalous acardiac fetus. Therefore, the sonographic diagnosis of TRAP sequence was confirmed. Conclusions We recommend considering the potential rare complications of monochorionic twin pregnancy which necessitates proper surveillance and intervention to monitor suitable growth of pump twin.

Twin Reversed Arterial Perfusion

Twin-Reversed Arterial Perfusion(TRAP) sequence or Acardia twin refers to a unique complication of mono-chorionic twin pregnancy in which a twin with an absent or rudimentary non functioning heart (acardiac twin) is perfused by its co-twin (pumping twin) through a large artery to artery placental shunt, often accompanied by a vein to vein shunt. Here we discussed about a clinical case of TRAP sequence came in established preterm labour and its management.

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.

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.

Twin Reversed Arterial Perfusion

Introduction:This study highlights a very rare case which was related to abnormal monochorionic twinning status. Case Report: This case (a 28 year old pregnant woman) came at this institute for ultrasonographic evaluation of herpregnancy status. Her ultrasonographic results were consistent with acardiac-acephalus twinning condition (which isalso known as, twin reversed arterial perfusion or TRAP sequence). Discussion: This monochorionic twin pregnancy isa severe form of twin-to-twin transfusion syndrome (TTTS) and severe TTTS has mortality rate of about 60–100%. Conclusion: This case is very rare showing prevalence of about 1/35,000 overall pregnancies and accounting 1.0% ofthe monochorionic twin pregnancies. Medicine Today 2020 Vol.32(2): 143-144
