THORACOOMPHALOPAGUS ET HAERNIA UMBILICALIS -CONJOINED TWINS IN SIMMENTAL CATTLE

Complete conjoined twins (duplicitas completa) are conjoined twins whose spinas are totally separated. Approximately half are stillborn, and a smaller fraction of pairs born alive have abnormalities incompatible with life. The case under report was a thoracoomphalopagus conjoined twins which had been delivered by caesarean operation on a Simmental cow. Conjoined twins whose vertebral columns were totally separated and two thoracic cavities were merged into one "thorax". In the shared thoracic cavity two hearts in its own pericardium were found. There were a lungs well developed. Twins were died before delivery. The diaphragms were separated thoracal and abdominal cavities. Each of twins had own heart, lungs, liver, spleen, stomach, guts, kidneys. There was umbillical haernia in both of twins. The pedigree of the affected animal showed neither inbreeding nor any other affected animal in relationship. A wide range of different chemicals and environmental factors are suspected or are known to be teratogenic agents in humans and in animals, for example: drugs, radiation, some infections or some environmental chemicals such as polychlorinated biphenyls, dioxin, organic mercury, etc. This cow wasn´t treated with any drugs or medication during or before pregnancy. Most of exploatation fields of natural gas in Croatia are very closed to this farm. The process of getting natural gas from underground has the potential of being environmentally destructive because it contains some dangerous substances (mercury) and small amounts of radioactive elements, so it could cause harmful effects on population living near. Redundant use of different pesticide in agricuture and forestry, also could be harmful for animals and humans. Cause of malformation in this case is unknown.
