摘　　要：目的评价旋转DSA及血管三维重建技术在颅内动脉瘤诊断中的价值。方法40例蛛网膜下腔出血患者应用传统DSA,旋转DSA及血管三维重建进行检查,对比不同方法对动脉瘤病变的显示情况。结果40例患者均确诊为颅内动脉瘤,共45个动脉瘤。常规正侧位DSA能显示存在动脉瘤病变,但仅极少数病例能明确显示瘤颈和载瘤动脉的关系。旋转DSA显示动脉瘤结构的能力较常规DSA明显提高。所有血管三维重建的图像都清晰显示了颅内动脉瘤瘤体、瘤颈形态及载瘤动脉关系。结论旋转DSA及血管三维重建技术对颅内动脉瘤病变结构显示极佳,尤其是三维重建技术,明显有助于提高对颅内动脉瘤的诊断和介入治疗。Objective To evaluate the value of rotational digital subtraction angiography （RDSA） and three dimensional（ 3 D） reconstruction technique in diagnosing intracranial aneurysms. Methods Forty patients with subarachnoid hemorrhage underwent conventional DSA, RDSA and angiographic 3D reconstruction. Effectiveness of each technique in showing the aneurysm structure was compared. Results All patients were diagnosed as intracranial aneurysms via angiography. Fine structures such as.aneurismal neck and connected artery were difficult to identify on conventional DSA, whereas these details were shown clearly by RDSA and 3 D arterial reconstruction. Conclusion RDSA and 3D reconstruction techniques, especially the latter, are effective and useful in diagnosing and interventional therapy intracranial aneurysms.
