脑CT在急性进展性脑梗死中的应用价值

目的:探讨脑CT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早期变化特点,并与71例非进展性脑梗死进行对比。结果:103例患者,70例脑CT出现异常(68．0％),其中进展组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％)。进展组患者病情进展至高峰时,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。结论:脑CT可作为早期诊断APCI的预测指标,导致神经功能恶化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。

The Study of Brain Computed Tomography in Acute Progressive Cerebral Infarction

Objective:To explore brain computed tomography(CT) early features in acute progressive cerebral infarc- tion (APCI) in order to provide important objective basis for clinical diagnosis and treatment.Methods:one hundred three patients with acute cerebral infarction were studied prospectively after 3.5～24 hours onset.Thirty—two APCI patients were analyzed in early features of brain CT and compared with that of 71 no—APCI patients.Results:In 103 patients, seventy patients (68%) indicated abnormal in conventional 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%).There were 16 patients (50%) with infarction volume enlarged,5 patients with hemorrhagic infarction,3 patients with new artery infarcted and 8 patients no significant change when the clinical symptoms were most serious in APCI group Conclusions:The early fea- ture of brain CT may be diagnosis predictor in APCI.The direct causes of progressive cerebral infarction are infarction volume enlarged,hemorrhagic infarction and re—infarction.
