螺旋CT对大面积脑梗死的诊断与鉴别诊断

目的探讨大面积脑梗死的螺旋CT诊断与鉴别诊断。方法回顾性分析45例大面积脑梗死患者完整资料,其中27例大面积脑梗死是脑血管栓塞引起,12例是其它部位栓子脱落引起,6例是由于外伤性血管损伤引起。45列患者均在临床症状出现后2 h²4 d内行头颅CT平扫,经积极治疗后均行头颅CT复查。结果 45例患者均在脑实质内出现大片状低密度影,累及脑灰白质。结论螺旋CT能准确诊断大面积脑梗死,特别是外伤后出现的大面积脑梗死时,为该病的治疗提供有价值的数据和资料支持,避免医疗引纷的发生。

APPLICATION OF SPIRAL CT SCANING IN MASSIVE CEREBRAL INFARCTION DIAGNOSIS AND DIFFERENTIAL DIAGNOSIS

Objective To explore diagnosis and differential diagnosis of massive cerebral infarction in spiral CT scaning. Methods 45 cases with massive cerebral infarction CT imaging manifestations and diagnosis were retrospectively analyzed. 27 cases were caused by brain vascular embolization, 12 cases were caused by the embolus detachment from other parts, 6 cases were caused by traumatic vascular injury. 45 cases with massive cerebral infarction after the clincal symptoms appeared 2 h - 24 d were examined by spiral CT scaning, and after treatment 45 cases were examind by spiral CT scaning again. Results 45 patients all appeared hypodense in the brain parenchyma involving on cerebral gray matter. Conclusion Spiral CT scaning can accurately diagnose massive cerebral infarction, especially in massive cerebral infarction occurred after trauma, it provide valuable data and information support the treament of disease, to avoid the occurrence of medical tangle.
