[Stark Industries PR gives a small statement Tuesday night notifying the public that Tony Stark will remain in CCU despite a previously positive timeline. The (extremely vague) report is that surgeons encountered unexpected complications that prevented the procedure from completing as planned. Investors are reassured that Mr. Stark left the company in good hands and various projects are proceeding according to his direct guidelines (which is crap, but nobody needs to know that).
Tony's friends are informed more directly that while the procedure successfully removed about 80% of the shrapnel, smaller pieces still remain. Deactivating the magnet in his chest was required for the procedure, which also required controlled cardiac arrest, and after six hours they didn't feel it was safe to continue removing the pieces.
More procedures are planned when he is stronger, in the next couple weeks.
Tony's in and out of consciousness for the next twelve hours, and will be awake (though hardly on his feet) in the morning. No visitors are allowed.]
