三维数字减影血管造影在脑血管病诊断中的应用

目的:探讨三维数字减影血管造影(DSA)在脑血管疾病诊断中的应用价值。方法:应用GE Innova3100平板数字减影机对42例脑血管病变患者行三维和二维DSA成像检查。对比分析应用二维数字减影血管造影患者的资料和应用三维数字减影血管造影患者的资料和结果。方法:应用二维数字血管造影发现动脉瘤19例,动静脉畸形3例;运用三维数字血管造影(3D-DSA)发现动脉瘤23例,3例动静脉畸形。结论:三维数字血管造影可以从多方位观察颅内血管的结构,可以提供更清晰的参考图像角度,能够发现微小的和被正常血管隐藏的动脉瘤,减少漏诊率,三维数字血管造影优于二维数字减影血管造影。

Application of Three Dimensional Digital Subtraction Angiography in the Diagnosis of Cerebral Vascular Diseases

Objective: To investigate the value of utilizing 3D digital subtraction angiography(DSA) in the diagnosis of cerebral vascular disease (CVD). Methods: Forty-two patients with CVD underwent 2D-DSA and 3D-DSA examination by using GE Innova 3100 flat panel plate DSA machine, and the information and results of patients using 2D-DSA were compared with those using 3D-DSA. Results: Nineteen patients with intracranial aneurysm and three patients with arteriovenous malformation were found by using 2D-DSA. While 23 patients with intracranial aneurysm and 3 patients with arteriovenous malformation were found by using 3D-DSA. Conclusion: 3D-DSA could observe cerebral vascular from multi-direction, provide more clear angle of reference images and could find small and hidden aneurysms by normal vascular, moreover, it could reduce the rate of misdiagnosis.
