目的探讨可逆性缺血性脑功能缺损(RIND)的临床及影像学特征。方法回顾性分析5例RIND患者的临床及影像学资料。结果 5例患者血压均正常,糖尿病1例,高脂血症2例。症状表现为肢体活动障碍者3例,动眼神经麻痹1例,昏迷1例。灌注成像(PWI)发现缺血责任病灶3例,磁共振T1、T2未发现责任病灶,弥散加权成像(DWI)未见有异常信号。结论部分RIND患者脑组织可能未发生水肿及梗死;RIND危险因素及发病机制可能同短暂性脑缺血发作及其他类型脑血栓形成存在一定差异。
Objective To investigate the clinical and imaging features of reversible ischemic brain dysfunction (RIND). Methods The clinical and imaging data of 5 patients with RIND were retrospectively analyzed. Results All 5 patients had normal blood pressure, 1 diabetes and 2 hyperlipidemia. Symptoms showed limb movement disorders in 3 cases, oculomotor nerve paralysis in 1 case, coma in 1 case. Perfusion imaging (PWI) found three cases of ischemic responsibility lesions, T1, T2 did not find a responsible lesion, there was no abnormal signal in DWI. Conclusion Some edema and infarction may not occur in brain tissue of patients with RIND. The risk factors and pathogenesis of RIND may be different from those of transient ischemic attack and other types of cerebral thrombosis.
