Missed this one in UW this morning and am a little confused. Description was of a watershed infarct, and question asked for the cause. They listed "hypoxic ischemia" or something very similar as the correct answer. I chose "carotid atherosclerosis". I understand their explanation that global ischemia leads to the pale infarct described in the watershed zone, but according to RR Path that can be caused by carotid atherosclerosis or thrombosis of a carotid atherosclerotic plaque. It seems like both of these answers are equally true - different ways of saying the same thing. Was this just a bad question, or did I miss something here? Anyone else remember this question... did I miss an important clue or something in the stem?
