Case 9. Female, 14 years, left EDAS. One day after the operation, her right limb clonus and she was conscious. She was found to have cerebral infarction after the operation. A, B DSA showed occlusion of bilateral internal carotid arteries and formation of smoke-like vessels before operation. C Preoperative MRI revealed chronic cerebral infarction lesions in bilateral centrum semiovale and left frontal cortex. D–G Preoperative CTP (D CBF is roughly the same on both sides; E CBV is roughly the same on both sides; F MTT bilateral frontal lobe slows down; G Tmax bilateral frontal lobe slows down). H One day after operation, a high signal intensity of the left frontal lobe can be seen on the DWI sequence, and acute cerebral infarction is considered. I Postoperative VEEG showed that F7, T3, and T5 (left posterior temporal and frontal lobe) were visible Ɵ wave low amplitude slow wave activity (arrow)
