In our case it is Ventral union of thoracopagus
with single heart.
XO = Xipho-omphalopagus; TO = Thoracopagus
; M = Male; F = Female;
Although conjoined twins, especially thoracopagus
type, are known to present several cardiac anomalies, a shared single four-chambered heart with triple-outlet left ventricle is a rare condition.
twins are conjoined twins united at the thorax, facing each other, often with partly fused or compromised hearts.
Chang and Eng Bunker were thoracopagus
twins born in Siam in 1811.
The earliest reported separation of thoracopagus
twins occurred in 1900 at the age of 12; one twin died and the other survived (Hoyle, 1990).
We strongly suggest that the lack of developmental stimulation caused by severe pulmonary dependency expected in thoracopagus
conjoined twins ought to be included in any consideration of bringing such babies to term, or once born, in providing them with respiratory support.
Conjoint twin baby delivered by CS was of thoracopagus
En terminos generales, los dos casos descritos corresponden a gemelos simetricos unidos (Monocephalus dipygus), clasificando el primero de ellos como Monocephalus thoracopagus
tetrabrachius tetrapus, por presentar fusion de cabeza y torax, asi como cuatro miembros anteriores y cuatro posteriores.
30-40%), abdomen (omphalopagus 25-30%), pyopagus (10-20%), pelvis (ischiopagus 20%), face (cephalopagus), skull (craniopagus 2-16%), back (rachipagus).
(8) Craniopagus and thoracopagus
separation is a tedious affair because they may share vital structures, while ischiopagus and pyopagus can be separated surgically and have good outcome.
with E/O fusion of the adjacent limbs, Single cardia, lung fields of the foetus on right side appears to be hyper inflated.
