旋转DSA在脑动脉瘤诊断中的价值

Diagnostic value of R-DSA for intracranial aneurysm

目的评价旋转DSA对脑动脉瘤的诊断价值。方法回顾性总结37例脑动脉瘤的旋转DSA影像表现,分析脑动脉瘤的位置、大小、形态、数目及检查方法。结果检出脑动脉瘤单发34例,多发3例。37例中查出脑动脉瘤39个,其中,后交通动脉瘤20个,前交通动脉瘤13个,颈内动脉瘤2个,其他部位4个;小型7个,中型18个,大型13个,巨型1个;囊状28个,梭状11个。结论旋转DSA能准确诊断脑动脉瘤。

Objective To evaluate the diagnostic value of rotary digital subtraction angiography （R-DSA）for intracranial aneurysms. Methods DSA imaging data of 37 patients with clinically suspected intracranial aneuryam, which included the location, size, shape and number of the lesions of aneurysm and the examination method were retrospectively summarized and analyzed. Results Among 37cases, 34 cases（91% ）were single aneurysms and 3 cases （9 % ）were multiple aneurysms. Among 39 aneurysms of 37 cases, 20 located in posterior communicating arteries, 13 in anterior communicating arteries, 2 in internal carotid arteries and 4 in other locations. For the size of the aneurysm（in diameter）, there were 7 small （ 〈0.5 cm）,18 middle （ 0.5-1.0cm ）, 13 large （1.1 -2.5cm）,and 1 giant （〉 2.5 cm） in 39 aneurysms. For the shape of the aneurysms, 28 were cystiform and 11 were fusiform. Conclusion R-DSA can accurately diagnose intracranial aneurysm.
