颅内动脉瘤诊断中3D-CTA的应用价值

The Value of Application of 3D-CTA in the Diagnosis of Intracranial Aneurysms

目的颅内动脉瘤诊断中3D-CTA的应用价值。方法采用回顾性方法分析我院2015年1月-2018年6月收治的50例蛛网膜下腔出血疑似颅内动脉瘤患者的临床资料,所有患者均给予3D-CTA、2D-DSA及3D-DSA检查,分析颅内动脉瘤的影像学表现及3D-CTA应用价值。结果50例蛛网膜下腔出血中经过手术或栓塞治疗确诊有53处颅内动脉瘤,3D-CTA、3D-DSA的检出率(98.11%、100.00%)、灵敏度(97.07%、97.89%)及特异度(88.68%、88.89%)均高于2D-DSA(86.84%、91.23%、80.45%),其差异有统计学意义(P<0.05),但3D-CTA、3D-DSA两者比较,差异无统计学意义(P>0.05)。结论3D-CTA诊断颅内动脉瘤的效果优于2D-DSA,可作为临床诊断颅内动脉瘤的首选方法,但结合3D-DSA可为临床诊治获取更多有用信息。

Objective To discuss the value of 3D-CTA in the diagnosis of intracranial aneurysms. Methods The clinical data of 50 patients with suspected intracranial aneurysms with subarachnoid hemorrhage admitted to our hospital from January 2015 to June 2018 were analyzed retrospectively.All patients were examined by 3D-CTA, 2D-DSA and 3D-DSA. The imaging manifestations of intracranial aneurysms and the value of 3D-CTA were analyzed. Results In 50 cases of subarachnoid hemorrhage, 53 intracranial aneurysms were diagnosed by operation or embolization. The detection rates of 3D-CTA and 3D-DSA(98.11%, 100.00%), sensitivity(97.07%, 97.89%) and specificity(88.68%, 88.89%) were higher than those of 2D-DSA(86.84%, 91.23%, 80.45%). The difference was statistically significant(P < 0.05). However, there was no significant difference between 3D-CTA and 3D-DSA(P > 0.05). Conclusion 3D-CTA applied on intracranial aneurysm is better than 2D-DSA which could be used as the first choice for clinical diagnosis of intracranial aneurysms, but it could get more information on diagnosis combined with 3D-DSA.
