Survey on 50 large hemispheric cerebral Infarction patients, the authors saw that: The patient was hospitalized in the first 24 hours accounted for 58 percent. The second day accounted for 34 percent. Disorder of consciousness accounted for 76 percent. The proportion of patients with damage to the left hemisphere dominant 62 percent compared to 38 percent on the right. Signs of the eyes looking to the hemisphere lesions occupy 74 percent of patients and there are about 26 percent of the large hemispheric cerebral infarction patients presented malignant brain edema. On the brain computerized tomography image, the authors found that: the rate of stenosis, occlusion in the middle cerebral artery (MCA) was 52 percent in the M1 segment
24 percent in M2 segment
22 percent in C4 segment of the carotid artery. The factors related to severe disability of large hemisphere cerebral infarction patients were the cardiovascular disease (OR = 6.1)
disorder of conscious onset (OR = 5.5) the first signs of eye rotation looked to the lesions hemisphere and occlusion in C4 segment of the carotid artery (with OR = 9.1).
