(sighs) mm. which is harder to see. it's more common to find a bleed or an infarct. you were looking for the wrong thing. nice job. could you take it out, like now? run a pipeline stent and restore the blood flow to the basilar? i mean, could that wake him up? it could. it could also kill him. does the family want to take that risk? but, um, you--you said that yesterday. you said it-- it was our last chance. this is... a long shot. oh. well, what does dr. hunt say? dr. hunt is in surgery, and paul is my patient. and it's your decision. (people speaking indistinctly) nancy, every second counts now. (crying) well, if there's a chance that... okay. okay.
