双源CTA与DSA诊断颅内动脉瘤的对比分析

目的对比分析双源CT血管成像(CTA)及DSA对颅内动脉瘤的检测效果,评估双源CTA对颅内动脉瘤的诊断价值。方法 2015年6月至2016年6月收治自发性蛛网膜下腔出血40例,均在入院1周内完善头部双源CTA及DSA检查。结果双源CTA及DSA均检出动脉瘤44个,两种方法显示动脉瘤部位一致,两种检查方法显示动脉瘤大小无统计学差异(P0.05)。DSA显示微小动脉瘤5个,接近颅底部位的颈内动脉C3~C5段动脉瘤4个;双源CTA对颈内动脉C3~C5段动脉瘤的检出率为100%,对微小动脉瘤的检出率为100%。结论双源CTA检查快捷、简单、准确,为颅内动脉瘤的一种快速检查方法。

Clinical diagnosis of intracranial aneurysms:DSA vs. dual source CTA

Objective To explore the value of dual source CT angiography (CTA) to the diagnosis of intracranial aneurysms. Methods DSA and dual source CTA were performed in 40 patients with subarachnoid hemorrhage (SAH), respectively. The number, size, location and morphology of the intracranial aneurysms detected by both the methods were analyzed. The detection rates of internal the aneurysms lacerum segment (C3), the cavernous segment (C4) and the clinoidal segment (C5) were compared between both the methods. Results A total of 44 aneurysms were detected by dual source CTA and DSA in 40 patients with SAH, respectively. The intracranial aneurysms, intracranial microaneurysms and internal carotid artery C3~C5 segments aneurysms detection rates of DSA and dual source CTA were both 100%. The sizes of long axes, short axes and necks of aneurysms detected by dual source CTA were insignificantly different from those detected by DSA (P>0.05). Conclusions Dual source CTA is a fast, simple, accurate and practical method to diagnose intracranial aneurysms, and dual source CTA examination, to a certain extent, can replace the DSA examination in the patients with intracranial aneurysms.
