A parasitic twin (also known as an asymmetrical or unequal conjoined twin) is the result of the processes that produce vanishing twins and conjoined twins, and may represent a continuum between the two. Parasitic twins occur when a twin embryo begins developing in utero, but the pair does not fully separate, and one embryo maintains dominant development at the expense of the other. Unlike conjoined twins, one ceases development during gestation and is vestigial to a mostly fully formed, otherwise healthy individual twin. The undeveloped twin is defined as parasitic, rather than conjoined, because it is incompletely formed or wholly dependent on the body functions of the complete fetus. The independent twin is called the autosite.Surgery was necessary for the infant to survive but the bill was too high for this couple to handle; a total of 10,000 yuan or $1,500 in the US. The couple looked for financial aid and donations from the government and others. They finally found enough money and the surgery went on its way. It was a success. The parasitic twin was taken out of the little girl's body and she now lives on a normal life.

Does this happen often? or is it rare ?
ReplyDeleteNot really. Usually parasitic twin will either vanish with no trace or have the little dead fetus remnants on the living baby when the mother gives birth. This happened once before in China in 2005.
