Seeing the picture of the baby with two heads, is your first reaction a charade or fear? Most people are staring at the grotesque look of two heads while completely ignoring the deadly truth about the connection between the back bones. This rare conjunctural malformation is not a simple "replicating paste" and the way in which the spinal column is integrated with the thorax directly determines the boundaries of the operation. You think it's just an extra head? It's a mistake to actually let a surgeon sweat on the operating table, the anatomical knot hidden under a shared vein. If this critical structure is not understood, any attempt at separation is tantamount to a direct death sentence. Do you dare to look at the bloody medical game behind this picture?
