摘　　要：目的评价旋转DSA在颅内动脉瘤血管造影诊断中的应用价值。方法回顾了45例分别施行过常规 DSA和旋转DSA的脑动脉瘤患者的血管造影图像,其中男29例,女16例,年龄8-67岁,平均42．6岁。常规DSA 为正位及侧位影像,旋转DSA 360°旋转采集图像。结果旋转DSA对45例脑动脉瘤患者均能做出正确诊断,且均能在适当的角度,清晰显示瘤体颈部的结构,开口大小和方向,准确的把血管弯折与动脉瘤鉴别开来。常规DSA 检查发现40例动脉瘤。其中15/40动脉瘤的载瘤动脉与周围血管关系不清,19/40动脉瘤的颈部显示不清。结论旋转DSA对颅内动脉瘤病变显示极佳,可更清晰地显示动脉瘤瘤体、瘤颈形态及载瘤动脉关系,为临床治疗提供更为准确的参考价值。Objective： To evaluate the value of rotational DSA in the diagnosis of intracranial aneurysms. Methods： Reviews of conventional DSA and rotational DSA were performed in 45 patients of intracranial aneurysms respectively, including 29 men and 16 women, the age ranging from 8 to 67 years, with the mean at 42.6. Results： In the 45 patients 40 aneurysms were found by conventional DSA and theoother five were only by the rotational DSA. Furthermore, conventional DSA examination could not clarify the relationships of 15 （15/40） aneurysms with their parentarteries and the vascular branch anatomy, and the aneurysmal neck could not be clarified in 19 （19/40） patients. However, shape of the aneurysms and visibility of the aneurismal neck could be clarified by the use of RDSA, and meanwhile, vascular anatomy could be indentified by the rotational DSA. Conclusion： R DSA is effective and useful in intracanial aneurysms. Fine structures such as aneurismal neck and connected artery can be clearly shown by RDSA, and more clear information is provided for treatment.
