“…It has been reported that in conjoined thoracopagus twins, the hearts were of great significance (Cywes et al, 1997) and cardiac abnormalities were seen in almost any type of fusion (Ambar et al, 2010), and (Mazaheri et al, 2014) stated that thoracopagus twins mostly present cardiac anomalies with about 90% cases of shared pericardium. In this study, the two hearts are of unequal sizes, with F1 having larger heart than F2, but each in a separate pericardium.…”

This report describes a case of thoraco-omphalopygopagus type of conjoined twins in one-humped camel (Camelus dromedarius) in Maiduguri, Nigeria. The conjoined camel fetuses were observed during postmortem at the Maiduguri Metropolitan Abattoir. Necropsy and radiography were carried out. There was thoracolumbar scoliosis in both fetuses, common thoracic and abdominal cavities separated by a diaphragm, fully developed but separate body features such as head, neck, limbs and tail. The heart, respiratory system and spleen were also separate but the fetuses shared a single large liver. Each fetus had separate gastrointestinal tract from mouth to cranial two third of jejunum that fused to form single caudal one third of jejunum and extended to the rectum. There were four ureters connected to a single bladder.There were bilateral kidneys and testicles located in the abdomen of each fetus. The findings of this report may assist to surgically resolve such cases when delivered alive for the survival of the twins or one of them. To the best of our knowledge, this is the first report of thoraco-omphalopygopagus twin in one-humped camel.

Fetal Echocardiographic Characteristics of Fused Heart in Thoracopagus Conjoined Twins

Echocardiography

Conjoined twins (CT) are rare with possible serious malformations in which soft tissue, bone, or some organs are joined in utero. The extent of cardiac fusion and intracardiac anatomy of CT determine the viability, natural history, and outcome of potential surgical intervention. Early prenatal diagnosis and assessment may provide a window of opportunity to counsel the family for their informed decision on the pregnancy and to plan for prenatal and perinatal care. In this report, we describe a case of thoracopagus twins diagnosed by fetal echocardiography at 23-week gestation. The 2 hearts fused at the atrial and ventricular levels. The outcome and review of literature on fetal echocardiographic characteristics of this malformation are discussed.

“…The literature highlights patients with anencephaly, shared gastrointestinal tract organs, and, particularly, cardiac abnormalities. 12 Andrews et al 13 , 14 classified the cardiac defects of conjoined twins into four groups: the presence of two hearts and two pericardia (group A); the presence of two hearts and one pericardium (group B); the presence of one heart, with fused atria and separated ventricles (group C); and the presence of cardiac fused atria and ventricles (group D). 13 , 14 …”

Dicephalus dipus dibrachius twins: report of an autopsy case

Dicephalus dipus dibrachius twins are a rare form of conjoined twins. An autopsy of conjoined dicephalus twins is reported. The diagnosis was performed during the pregnancy and the family received a judicial authorization for termination of pregnancy. The preterm newborn progressed to cardiac arrest and died following a court order to terminate the pregnancy. The conceptus presented two arms, two legs, a trunk, two heads, and a single umbilical cord. The two spinal columns presented vertebral fusion in the sacral region. The heart exhibited complex malformations. The external genitalia were female; and cytogenetic analysis confirmed female sex (46, XX). This analysis also corroborated the etiopathogenic hypotheses described for this abnormality, which proposes failures in embryonic formation rather than specific chromosomal alterations. Current identification of cases by ultrasound permits medical management and multidisciplinary action with the family, enabling the legal termination of pregnancy.
