The only medical issue that I'm aware of that absolutely requires the premature ending of a pregnancy before the child can survive being birthed is a tubal pregnancy.
In every other medical situation, the child can be brought to some level of viability if not fully to term, and it is better and safer for the health of the mother as well as the child to deliver a live baby under the supervision of a medical team that is committed to the care of both patients.
Also, most D&Cs are done after a pregnancy has already terminated, whether through a miscarriage or a live birth.
