“…5 In human medicine, the nonamorphous twin is commonly referred to as the pump twin because it provides vascular perfusion to the acardiac twin through a process called twin-reversed arterial perfusion. In this process, deoxygenated blood from the pump twin does not return directly to the dam through the placenta; instead, that blood perfuses the acardiac twin through placental arterial anastamoses before returning to the maternal circulation.…”

HistoryA 4-year-old Holstein cow from the Washington State University dairy was artificially inseminated 2 times during her second lactation. Pregnancy was diagnosed via transrectal palpation and confirmed with ultrasonography 33 days after the second artificial insemination. One fetus with an apparently normal heartbeat was detected during ultrasonography. The pregnancy was confirmed at 75 and 185 days of gestation via transrectal palpation, and the cow calved after a gestation of 291 days. A clinically normal healthy calf was born, which was followed by the expulsion of a separate mass of hair-covered fetal tissues (Figure 1). The fetal tissues were submitted to the Theriogenology Service at Washington State University for evaluation.The mass measured approximately 30 X 20 X 15 cm (12 X 8 X 6 inches) and weighed 4.41 kg (9.7 lb). It was ovoid in shape, and approximately 80% of its surface was covered in black and white hair. It was asymmetric with a suggestive cranial-caudal orientation, and there were anatomic structures similar to a tail and anus at the caudal end. A 10-cm-diameter fluid-filled cystic structure was evident on the ventral aspect, near the location at which fetal membranes exited the mass. All fetal membranes were not submitted for examination. Figure 1-Photograph of a hair-covered fetal mass that was expelled after the birth of a healthy Holstein calf. There is a cystic dilatation in the ventral aspect of the fetus and a placental attachment projecting caudally. Bar = 30 cm.

“…The prognosis of isolated D-TGA is promising with appropriate management. Analyzing of these cases (3,(28)(29)(30)(31)(32)(33)(34)(35)(36)(37) gave insight to us on the intervention of D-TGA cases.…”

Background: Dextro-transposition of the great arteries (D-TGA) is a rare congenital heart disease, as it affects only 0.02-0.05% of live births. It is the second most common cyanotic heart disease following Tetralogy of Fallot. It has a male predominance. Fetal echocardiography is an optimal method for prenatal diagnosis of fetal D-TGA. In twin pregnancies, fetal D-TGA in one twin is very rare, especially in monochorionic-diamniotic twin pregnancies. Herein, we report a case of D-TGA in one twin in two dichorionic-diamniotic twin pregnancies and one monochorionic-diamniotic twin pregnancy from January 2018 to June 2021.Case Description: One twin with D-TGA was diagnosed by fetal echocardiography in the second trimester, and the co-twin was normal in all three cases. A multidisciplinary team provided extensive counseling regarding the D-TGA twin and the co-twin, and adequate perinatal management was provided.In cases 1, 2, and 3, the mothers underwent cesarean sections at 37 weeks + 2 days, 34 weeks + 5 days, and 36 weeks + 1 day, respectively. In case 1, which involved a female D-TGA neonate with birth weight 2,410 g, an emergent atrial septostomy was performed at 20 h after birth, and the neonate underwent atrial switch operation (ASO) 24 days after birth. In case 2, involving a male D-TGA neonate with a birth weight of 2,380 g, ASO was performed 24 days after birth. In case 3, involving a female D-TGA neonate with birth weight 2,240 g, ASO was performed 19 days after birth and delayed sternal closure was performed 4 days later. All six infants showed normal development during follow-up. Conclusions:Early antenatal diagnosis of D-TGA in one fetus of a twin pregnancy is significantly important. A multidisciplinary team should carry individual evaluation and integrated management of the D-TGA twin and co-twin during the pregnancy and perinatal period. After birth, delayed ductus arteriosus closure in the D-TGA twins should be performed when necessary and individualized timings for arterial switch operation should be considered.

“…Acardia can occur in an unusual setting with cyclopia and aprosencephaly in a twin fetus because of TRAP [5]. A variety of abnormalities could indeed be very broad to note also that an acardiac, anencephalic twin harbored a serious cardiac type defect, which was a transposition of great arteries [15]. The cardiac development could be impaired at a very varied stage, ranging from a complete lack of the heart through hypoplastic cor triloculare to a malposition of a relatively well-developed heart [16].…”

Acardiac fetuses are consequences of twin reversed arterial perfusion (TRAP). Here the authors present a case of 40-year-old gravida IX who gave birth to a healthy, 2,900 g female child by a cesarean section. Additionally amorphic 1,020 g maldeveloped fetus was removed. There was a diamnion monochorionic type of twin placenta with incorrect single umbilical arteries (SUA) both in umbilical cord of healthy fetus and in atrophic second umbilical cord. A malformed fetus developed a rather well formed lower leg with four digital foot and oval shape amorphous body mass with omphalocele and eventration of the intestines. X-ray picture showed well visible metatarsal and femur bone and anatomically undefined bones cluster in the central part. A cavity of fetal body contained intestines -the only one well-formed organ, nests of heterotopic pilosebaceous residues, remnants of adrenal glands, well-formed ganglia, and nests of neural tissue covered by neuroepithelium.
