摘要
目的 :MSCTA(多层螺旋CT血管造影)在颅内动脉瘤诊断中的应用价值分析。方法 :选取在本院就诊的动脉瘤蛛网膜下腔出血的患者37例,术前均行MSCTA和DSA(数字减影血管造影)检查。比较MSCTA和DSA诊断颅内动脉瘤的准确性的差异;比较MSCTA和DSA显示颅内动脉瘤类型的差异;以及MSCTA和DSA显示大脑中动脉瘤对比。结果 :术中发现45个颅内动脉瘤,其中MSCTA检查发现41个颅内动脉瘤,准确率为91.11%;DSA检查发现38个颅内动脉瘤,准确率为84.44%;两种检查方法发现颅内动脉瘤的准确率的差异无统计学意义。MSCTA检查4例颅内动脉瘤未显示,其中颈内动脉瘤2例,大脑后动脉瘤1例,后交通动脉瘤1例;DSA检查7例颅内动脉瘤未显示,其中颈内动脉瘤3例,大脑前动脉瘤1例,大脑中动脉瘤1例,前交通动脉瘤2例。DSA检查不能明确诊断左前交通动脉处造影剂充盈为动脉瘤,MSCTA检查可较清楚的显示前交通处动脉瘤,说明MSCTA检查对DSA检查有很好的补充作用。结论 :虽然MSCTA检查在发现颅内动脉瘤的准确率方面与DSA检查无显著差异,但对DSA检查有很好的补充作用。
Objective Application value of MSCTA in the diagnosis of intracranial aneurysms. Methods 37 patients with subarachnoid hemorrhage in our hospital were selected and underwent MSCTA and DSA examination before operation. Com-parison of the accuracy of MSCTA and DSA in the diagnosis of intracranial aneurysms; Comparison of MSCTA and DSA showed differences in the types of intracranial aneurysms; And the comparison of MSCTA and DSA in the middle cerebral artery aneu-rysm. Results 45 of intracranial aneurysms were found in the operation, 41 intracranial aneurysms was found by MSCTA, and the accuracy was 91.11%; 38 of intracranial aneurysms was found by DSA, and the accuracy was 84.44%; There was no sig-nificant difference in the accuracy of the two methods .4 cases of intracranial aneurysms did not show by MSCTA examination, 2 cases of internal carotid artery aneurysm, 1 cases of cerebral aneurysm, 1 cases of posterior communicating artery aneurysm; 7 cases of intracranial aneurysms did not show by DSA examination, 3 cases of internal carotid artery aneurysm, 1 cases of an-terior cerebral artery aneurysm, 1 cases of middle cerebral artery aneurysm, 2 cases of anterior communicating artery aneurysm. DSA examination can’t be a clear diagnosis of left anterior communicating artery angiography agent filling for aneurysm, MSC-TA examination can clearly show the former Department of communications artery aneurysm, MSCTA check for DSA inspection has a very good complementary role. Conclusion Although there was no significant difference in the accuracy of MSCTA and DSA in the diagnosis of intracranial aneurysm, DSA had a very good complementary effect on DSA.
