摘要
目的分析三维数字减影血管造影术(3D-DSA)和三维CT血管造影(3D-CTA)对颅内动脉瘤的诊断价值。方法选择2016年5月至2018年4月在本院接受手术治疗的疑似颅内动脉瘤患者94例为研究对象,均接受3D-DSA及3D-CTA检查,以3D-DSA检查结果为金标准,分析检查结果。结果 94例疑似颅内动脉瘤患者经3D-DSA明确诊断者92例,颅内动脉瘤107个,其中单发者80例,双发者10例,多发者2例;直径<3 mm的颅内动脉瘤病灶31个、3～5 mm的47个、>5 mm的29个。3D-CTA检出颅内动脉瘤患者86例(93.48%),检出颅内动脉瘤病灶99个(92.52%)。A、B组经3D-CTA检查颅内动脉瘤患者例数及病灶数量与3D-DSA检查的符合率均显著高于C组,差异具有统计学意义(P<0.05)。甲组经3D-CTA检查颅内动脉瘤患者例数及病灶数量与3D-DSA检查的符合率显著低于乙、丙组,差异具有统计学意义(P<0.05)。结论3D-CTA对颅内动脉瘤的检查结果与3D-DSA检查的相符率较高,有助于为临床提供图像清晰、准确率较高的诊断依据。
Objective To analyze the diagnostic value of three-dimensional digital subtraction angiography(3D-DSA)and three-dimensional CT angiography(3D-CTA) in intracranial aneurysms. Methods From May 2016 to April 2018, 94 patients with suspected intracranial aneurysms who underwent surgical treatment in our hospital were selected as the study objects. All patients underwent 3D-DSA and 3D-CTA examinations, the results of 3D-DSA were taken as the gold standard and the examination results were analyzed. Results Of the 94 patients with suspected intracranial aneurysms, 92 cases were diagnosed by 3D-DSA and with 107 intracranial aneurysms, including 80 with single lesions, 10 with double lesions, and 2 with multiple lesions;31 lesions of intracranial aneurysms with diameter <3 mm, 47 lesions with diameter of3 ~5 mm and 29 lesions with diameter >5 mm. 3D-CTA detected 86 cases of intracranial aneurysms(93.48%) and 99 lesions of intracranial aneurysms(92.52%). The coincidence rate of the number of patients and lesions of intracranial aneurysms examined by 3D-CTA and 3D-DSA in the group A and B were significantly higher than those in the group C,and the differences were statistically significant(P<0.05). The coincidence rate of the number of patients and lesions of intracranial aneurysms examined by 3D-CTA and 3D-DSA in the group one were significantly higher than those in the group two and three, and the differences were statistically significant(P<0.05). Conclusion The coincidence rate between the results of 3D-CTA and 3D-DSA for intracranial aneurysms is higher, which is helpful to provide the diagnostic basis of clear image and higher accuracy for clinic.
