Objective To explore the application value of spiral CT angiography in etiological diagnosis of spontaneous intracranial hematoma before surgery.Methods 48 patients with spontaneous intracranial hematoma following surgical indication assessed by CT scan were ascertained etiological diagnosis performed by CT angiography before surgery.Results The causes of intracranial hematoma were cerebral aneurysm(2 patients),arteriocenous malformation (5 patients),hypertension(40 patients),and no image in one patient performed by CT angiography.Conclusion CT angiography has important value in etiological diagnosis of spontaneous intracranial hematoma before surgery.

目的探讨螺旋CT脑血管造影(CTA)在颅脑损伤致脑疝术后早期评估脑循环状况中的应用价值。方法28例颅脑损伤导致脑疝患者于手术后6h内行CT平扫,平扫后立即行CTA检查24h后再次行CT平扫,并对两次CT平扫与CTA结果进行对照分析。结果26例患者术后6h内CT平扫显示手术区血肿均已清除,未见缺血性脑梗死改变。10例患者CTA示大动脉显影明显异常,手术24h后CT平扫示7例患者发生脑梗死。结论CTA对了解脑疝术后早期的脑循环状况,指导临床早期治疗和进行预后判断有重要参考价值。
