患者男性,27岁,患有MELAS(线粒体、脑肌病、乳酸酸中毒和卒中样发作)综合征,于6d前出现典型的卒中样发作:右半身轻瘫、偏盲。TCD显示所有颅内动脉,收缩-舒张期血流速度明显增加,搏动指数很低(双侧0.5),在重呼吸试验(rebreathing test)时无明显改变,再者~(133)Xe二维局部脑血流(脑显影32c.Novo)测定(初斜率指数单位),左半球为85.5,右半球90.7(20
The patient, a 27-year-old man with MELAS (mitochondrial, encephalomyelitis, lactic acidosis and stroke-like syndrome), developed typical stroke-like episodes by 6 days: right hemiparesis, hemianopia. TCD showed all intracranial arteries, systolic-diastolic flow velocity was significantly increased, pulsatility index was low (bilateral 0.5), no significant change in the rebreathing test (rebreathing test), and ~ (133) Xe two-dimensional local Cerebral blood flow (brain development 32c.Novo) determination (initial slope index unit), left hemisphere 85.5, right hemisphere 90.7 (20
