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

TRAP syndrome is a rare complication of monochorionic twin pregnancy. It is characterized by the association of an acardiac twin with a healthy twin. The acardiac twin is a parasite who put the healthy twin at high risk of cardiac failure. We report a case in a 25-year-old Malagasy woman, primigravida, who had a consultation at gestational week 31 for significant dyspnea and a threat of premature delivery. Ultrasound scans discovered an acute polyhydramnios, fetus with anasarca and low cardiac activity, and a para-fetal mass. She gives birth to a male newborn and an acardiac twin without head an upper body. The first twin died short time after birth.

AbstractTwin reversed arterial perfusion (TRAP) syndrome is a rare but severe complication of monozygotic monochorionic twin pregnancies. The outcome is invariably fatal for the abnormal twins and for 50-75% of the normal co-twins. The prenatal diagnosis of the TRAP always has to be presumed in a multiple pregnancy within which a twin pair grows whenever cardiac activity can not be proved echographically. We present discuss – based upon literature research – pathogenic mechanisms, pathologic-anatomic, echographic diagnosis and management of these high-risk pregnancies.

Monochorionic-triamniotic triplet pregnancy with twin reversed arterial perfusion (TRAP) sequence is one of the rare complications of multiple pregnancy and has been reported by only a few. Here, we report a case of monochorionic-triamniotic triplet pregnancy with TRAP sequence successfully treated with radiofrequency ablation, which did not develop polyhydramnios and heart failure although the estimated weight of the acardiac fetus increased twice as much as that of the direct pump fetus. Interestingly, the anastomosed blood vessels between the direct and indirect pump fetuses comprised a parallel circuit, which provided blood flow to the acardiac fetus. We hypothesized that the burden on the pump fetus in monochorionic pregnancy with TRAP sequence would be different between triplet and twin pregnancies.
