Twin Reversed Arterial Perfusion

We received a malformed Messinese Black goat foetus for examination. The foetus was part of a triple gestation, from which two male kids presented no morphological abnormalities and underwent regular slaughtering. X-ray examination and necropsy were performed. On the basis of gross and radiological findings the malformation was classified as acardius acephalus. In human medicine, acardius is a rare and severe abnormality reported as a unique complication of monozygotic twin pregnancies, and is known as twin-reversed arterial perfusion (TRAP).

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).

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.

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

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.

AbstractTwin reversed arterial perfusion (TRAP) sequence is a rare but severe condition that affects monochorionic (MC) multifetal pregnancies. In twin pregnancies, it is characterized by a normally developed twin and another twin with missing heart function (acardiac twin or TRAP twin). A variety of risks and complications may affect the normal twin. Management of such pregnancies can be either expectant or interventional. We report four cases of TRAP sequence treated in our institutions and supply an overview on currently existing literature. This case series demonstrates the heterogeneity in manifestations and clinical course of patients affected by this condition. Furthermore, it includes an acardius amorphous of considerable size delivered at 35.6 weeks of gestation.

Twin reversed arterial perfusion (TRAP) sequence is a rare and severe complication specific to monochorionic twin pregnancies, involving the presence of an acardiac twin and a structurally normal co-twin (pump twin). We report on the case of a33-year-old female with a biamniotic monochorionic twin pregnancy complicated with TRAP sequence and polyhydramnios. The patient underwent fetoscopic termination of the acardiac twin and at 34 gestational weeks (GW) was readmitted with aretroplacental hematoma. The patient gave birth through caesarean section to a living female fetus, weighing 1480 g. To the best of our knowledge, this is the first case reporting a twin pregnancy with TRAP sequence complicated with retroplacental hematoma.

Ultrasound Surveillance

Ultrasound has revolutionised the management of multiple pregnancies and their complications. Increasing frequency of twin pregnancies mandates familiarity of all clinicians with the relevant pathologies and evidence-based surveillance and management protocols for their care. In this review, we summarise the latest evidence relating to ultrasound surveillance of twin pregnancies including first trimester assessment and screening, growth surveillance and the detection and management of the complications of monochorionic pregnancies including twin-to-twin-transfusion syndrome, selective fetal growth restriction, twin reversed arterial perfusion sequence and conjoined twinning.
