旋转DSA技术在脑动脉瘤诊断中的应用

目的:对78例蛛网膜下腔出血(SAH)的患者行脑血管DSA(digital subtraction angiography)造影,并对常规和旋转DSA的影像表现进行比较分析.方法:常规经右股动脉采用Seldinger技术穿刺插管至两侧颈内动脉、一侧椎动脉行全脑血管造影.每根行正位、侧位,再加旋转DSA造影.根据DSA的影像表现对脑动脉瘤的大小、分布、形态、瘤颈、有无血栓、破口及血流情况等进行分析.结果:64例脑动脉瘤患者常规正侧位造影显示动脉瘤者51例的55枚动脉瘤,检出率为76.4%(55/72);通过旋转DSA造影检出增加了13例的17枚动脉瘤,检出率提高了23.6%(17/72).结论:DSA造影是诊断脑动脉瘤的标准方法,而三维旋转DSA技术为多角度观察提供了方便,有效排除了血管成角、重叠等因素的干扰,可清晰显示脑动脉瘤的大小、形态、瘤颈、有无血栓、破口及血流等情况,特别是提高了小动脉瘤及复杂动脉瘤的检出率,对脑血管病变的诊断和治疗具有很大的应用价值.

Application of Rotational DSA Technology in Diagnosing Cerebral Aneurysm

Objective:78 cases of subarachnoid hemorrhage(SAH) were performed cerebrovascular DSA inspection,and compared the imaging features of rotational DSA and conventional DSA.Methods:Puncture the right femoral artery using routine Seldinger method and endhole catheter into both sides of the internal carotid and one side of the vertebral artery for cerebrovascular DSA inspection.Each arteries were performed adem position DSA and rotation DSA inspection.According to the imaging features of DSA,we analyse cerebral ...
