There's an interesting medicolegal issue arising out of TX, a pregnant women who suffered a pulmonary embolism in November and died (when she was 14 weeks pregnant).
However, the body has been kept on life-support all this time (against her and her husband's wishes), due to an ambiguous TX state law (TEX HS. CODE ANN. §166.049) which actually blocks the ability of the patient and family to decide:
A person may not withdraw or withhold life-sustaining treatment under this subchapter from a pregnant patient.
Here's an article discussing the situation:
And here's the emergency motion for expedited relief, filed on behalf of the family just yesterday, requesting an order to disconnect her from life support by arguing the TX law was misinterpreted by the hospital; the motion points out the women is no longer a "pregnant patient", but a "pregnant dead body", and hence the law doesn't apply:

The situation raises some interesting medico-ethical issues of when a patient's right to decide what happens to their body after death is overriden by the interests of the State to take that right away (in this case, forcing the dead body to serve as an incubator, despite the likelihood of the fetus of having experienced some due to anoxia and against the wishes of the dead woman and her family).
