【摘要】 目的:分析颅脑损伤首次CT检查与临床不符的表现和原因,探讨其临床应用价值。方法:通过对首次CT检查阴性而临床症状较重及首次CT检查后又出现新的临床症状的37例颅脑损伤患者的临床资料进行回顾性分析总结。结果:37例复查CT出现阳性表现有迟发性血肿15例、脑挫裂伤9例、弥漫性脑肿胀8例、外伤性脑梗死3例、脑干损伤2例,可由不同原因引起。结论:首次CT检查与临床不符因素包括扫描时机、机器原因、医师诊断水平、病灶不典型等;对首次CT检查阴性而临床症状较重患者,伤后3天内是病情最易发生变化时期,应及时复查C T;对首次CT检查后又出现新的临床症状,应立即复查CT了解病情。更多还原

【Abstract】 Objective:To analyse the cause and manifestation of negative findings on the first CT images compared to serious clinical symptoms in patients with traumatic craniocerebral injury and to discuss the clinical value.Methods:The clinical data of 37 traumatic craniocerebral injury patients without the positive findings on the first CT images with serious clinical symptoms and the new clinical symptoms appeared after the first CT were analysed retrospectively.Results:Compared with the first CT images of patients with serious clinical symptoms in patients,the repeated CT scans revealed delayed intracranial hematomas in 15 cases,cerebral contusion in 9 cases,diffuse cerebral swelling in 8 cases,traumatic cerebral infarcation in 3 cases and brain stem injury in 2 cases,which inight be attributable to different causes.Conclusion:The cause of the first CT images inconsistent with clinical symptoms include scanning time,machinery equipment,the diagnostic skills of the doctors,and atypical focus.The repeated CT scans is very important for the patients of negative findings on the first CT images compared to serious clinical symptoms becuse the disease process often dramaticly changes in three days;in order to know the disease process,the repeated CT scans must be done immediately for the patients with the new clinical symptoms after the first CT.更多还原
