目的 :了解CO中毒后迟发性脑病 (DEACMP)的影像学、电生理及临床特点。方法 :对 184例DEACMP患者的假愈期、急性期、恢复期的临床表现和头部CT、MRI、EEG、BAEP、TCD、rCBF、智能等进行对比分析。结果 :CT异常率 91 3 % ,MRI异常率 97% ,EEG、TCD、BAEP均为 10 0 %异常 ,智力测验 10 0 %异常。结论 :影像学改变轻于临床表现 ,电生理改变与临床一致 ,EEG在假愈期有意义 ,脑血流检测能真实反映病情 ,智能恢复较慢 ,对判断患者真正痊愈有价值。及时、长期坚持治疗和锻炼有助于患者的恢复。
Objective: To understand the imaging, electrophysiology and clinical features of delayed encephalopathy (COAC) after CO poisoning. Methods: The clinical manifestations, head CT, MRI, EEG, BAEP, TCD, rCBF and intelligence in 184 patients with DEACMP were compared. Results: CT abnormality rate was 91.3%, MRI abnormality rate was 97%, EEG, TCD and BAEP were all 100% abnormal and intelligence test was 100% abnormal. Conclusion: The change of imaging is lighter than that of clinical manifestation. The change of electrophysiological and clinic is consistent. The EEG is of significance in the false period, the cerebral blood flow test can truly reflect the condition, and the intelligent recovery is slow. It is valuable to judge the real recovery of the patient. Timely, long-term adherence to treatment and exercise will help patients recover.
