3D-CTA与3D-DSA在急性破裂性颅内动脉瘤诊断中的价值

The Value of 3D-CTA and 3D-DSA in the Diagnosis of Acute Ruptured Intracranial Aneurysms

目的分析三维C T血管造影(Three-Dimensional Computed Tomography Angiography,3D-CTA)与三维数字减影血管造影(Three-Dimensional Digital subtraction angiography,3DDSA)在急性破裂性颅内动脉瘤诊断中的价值。方法选取我院收治的90例疑似急性破裂性颅内动脉瘤患者纳入研究,均行3D-CTA与3D-DSA检查,以手术病理为"金标准",比较3D-CTA与3D-DSA检查准确性。结果 3D-CTA诊断急性破裂性颅内动脉瘤灵敏度为91.46%(75/82),特异度87.50%(7/8),准确性91.11%(82/90);3 D-D S A诊断急性破裂性颅内动脉瘤灵敏度为9 8. 7 8%(8 1/8 2),特异度100.00%(8/8),准确性98.89%(89/90),Kappa值均>0.4;3D-DSA检查方式灵敏度与准确性均明显高于3D-CTA检查方式(P<0.05)。结论相较于3D-CTA,3D-DSA诊断急性破裂性颅内动脉瘤具有较高准确性,可为患者临床诊治提供可靠参考依据。

Objective To analyze the value of three-dimensional computed tomography angiography(3 D-CTA)and three-dimensional digital subtraction angiography(3 DDSA)in the diagnosis of acute ruptured intracranial aneurysms.Methods A total of 90 patients with suspected acute ruptured intracranial aneurysms were enrolled into the study.All of them were examined by 3 D-CTA and 3 D-DSA.With surgical pathology as the golden standard,the accuracy was compared between 3 D-CTA and 3 D-DSA.Results The sensitivity,specificity and accuracy of 3 D-CTA in the diagnosis of acute ruptured intracranial aneurysms were 91.46%(75/82),87.50%(7/8)and 91.11%(82/90),respectively,while those of 3 D-DSA were 98.78%(81/82),100.00%(8/8)and 98.89%(89/90),respectively.The Kappa values were larger than 0.4.The sensitivity and accuracy of 3 D-DSA were obviously higher than those of 3 D-CTA(P<0.05).Conclusion Compared with 3 D-CTA,3 D-DSA is of high accuracy in the diagnosis of acute ruptured intracranial aneurysms,and it can provide a reliable reference for clinical diagnosis and treatment.
