Their circulation is connected, the dead twin is going to give the live twin septicaemia. If a person has a gangrenous limb, we can amputate it. But what to do if the whole of your conjoined twin is gangrenous?

Given this, they can live for a few hours, but once one twin is dead, death for the other becomes imminent and inevitable.
