摘要
目的：观察脑CT及脑电地形图(BEAM)在急性进展性脑梗死(APCI)变化特点,为临床早期诊断和治疗提供客观依据。方法：对103例发病2.5～24小时、急性脑梗死患者进行前瞻性研究,其中APCI患者32例,分析脑CT和BEAM早期变化特点,并与71例非进展性脑梗死进行对比。结果：脑CT：103例患者,70例脑CT出现异常(68.0％)。进展组32例患者,27例(84.4％)出现脑梗死早期表现,明显高于非进展组(43例,60.6％),病情进展至高峰时,脑CT显示,16例(50％)出现梗死体积增大,5例(15.6％)有出血性梗死,3例(9.4％)有新部位的梗死,8例(25％)梗死体积无明显变化。BEAM检查：两组患者异常率为91.4％。进展组患者病变区δ频带平均功率值高于非进展组,并且异常部位波及范围较大。结论：脑CT和BEAM可作为早期诊断APCI的预测指标。导致病情进展的直接原因可能与梗死体积增大、出血性脑梗死和再梗死有关。
Objective： To observe brain computed tomography （CT） and brain electrical activity mapping （BEAM） early features in acute progressive cerebral infarction （APCI） in order to provide important objective basis for early clinical diagnosis and treatment. Methods： one hundred three patients with acute cerebral ixffarction were studied prospectively after 2.5 - 24 hours onset. Thirty - two patients with APCI were analyzed in early features of brain CT and BEAM and compared with that of 71 patients without APCI. Results： In 103 patients, seventy patients （68%） were abnormal in CT after cerebral infarction onset. The positive rate （27/32, 84.4% ） of brain CT in APCI group was higher than that of no - APCI group （43/71, 60.6% ）. When the clinical symptoms were most serious, there were 16 patients （50%） with infarction enlarged, 5 patients with hemorrhagic infarction, 3 patients with new infarcted and B patients without significant change in APCI group. The positive rate of BEAM in two groups was 91.4% and higher than that of brain CT. The δ mean power in APCI group was higher than that of no - APCI. Conclusions： Brain CT and BEAM may be predictors of early diagnosis in APCI. The direct causes of progressive cerebral infarction may be releted to infarction volume enlarged, hemorrhagic infarction and reinfarction.
