What are Siamese twins?
Siamese twins, also known as connected twins, are the same twins, which did not completely separate during the early embryonic development. In most cases, identical twins consist of a single fertilized egg, which during pregnancy will soon be divided into two separate embryos. Siamese twins appear when the eggs do not completely divide, resulting in two infants that are connected together. This occurrence is relatively rare, with only one in 200,000 live births.
The prognosis for Siamese twins depends on several factors. First, most of the connected twins share the placenta and amniotic bag during the development of the fetus. In some cases, one twin may receive more nutrition than the other or the placenta may not be able to provide sufficient support for two infants at a time. This can also occur in fully separate identical twins. For this reason, between 40 and 60 percent of all connected twins will arrive.

Both children can only have one heart or liver with each other, which means that the only organ must support both infants at the same time. This can lead to a huge burden on both children when they grow because the organs are not made to support two growing children at the same time. Many times one or both children die during the first few years of life.
In some cases, the twins may be separated if the parts of the body they share are not associated with any main veins or arteries and if they do not share any main organs. Operations are often risky and in many cases both twins do not survive. The decision to separate Siamese twins is important, especially if one twins are endangered than the other.
