短暂性脑缺血(TIA)是脑梗塞最明显的先驱症状,比较少见的是短暂性神经缺损症状(DNT)可能先于脑实质出血(HIP)。本研究对平均年龄为61.6±16.3岁的23例病人采用标准化表格详细填写既往史、临床症状、神经放射学的表现和两个月时的演进方式,HIP经放射学和尸体解剖确诊,并排除外伤及出血性梗塞。DNT的诊断标准为HIP之前出现局灶性的神经系统缺损,在24小时内经或未治疗后消失。结果238例病人中有17例(占7.1％)在HIP之前出现一次或几次DNT,有一例病人出现6次不同部位的DNT,HIP和DNT的间隔期为1月到5年,11例DNT的临床表现被确诊,其中50％为纯偏身运动障碍;30％为合并或不合并运动缺损的言浯功能障碍;40％病例DNT出现在HIP缺损
Transient cerebral ischemia (TIA) is the most obvious precursor to cerebral infarction. Less often, transient neurological deficit (DNT) may precede cerebral parenchymal hemorrhage (HIP). In this study, 23 patients with an average age of 61.6 ± 16.3 years were asked to fill in the past history, clinical symptoms, neuroradiology and evolution at two months in a standardized form. HIP was diagnosed by radiology and autopsy and exclusion Trauma and hemorrhagic infarction. The diagnostic criteria for DNT were focal neurological deficits prior to HIP, which disappeared with or without treatment within 24 hours. RESULTS: Seventeen of 238 patients (7.1%) had one or more DNTs before HIP. One patient had six DNTs at different sites. The interval between HIP and DNT ranged from 1 to 5 years and 11 patients with DNT Of the clinical manifestations were diagnosed, of which 50% of pure partial body dyskinesia; 30% with or without motor impairment of speech and 浯 dysfunction; 40% cases of DNT in HIP defects
