Prediction of worsening consciousness from edema after hemispheric infarction.
We sought to develop a risk profile that would predict worsening consciousness from edema after hemispheric infarction. Charts were reviewed correlating initial computed tomography scan, neurologic examination, demographic features, and ischemic mechanism with worsening consciousness from massive edema after hemispheric infarction. An edema risk profile composed of two of three clinical factors (gaze preference, hemiplegia, or hemineglect) and evidence of acute cortical infarction on initial computed tomography scan highly correlated with the later development of worsening consciousness from edema. The edema risk profile correlated with worsening consciousness from edema after hemispheric infarction. The profile requires prospective verification before use for family counseling, for anticipatory care, and for randomizing patients in acute stroke trials aimed at controlling the formation and sequelae of edema after ischemic stroke.
