| 目的 评价旋转DSA及血管三维重建技术在颅内动脉瘤血管造影诊断中的应用意义。方法 8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 所有患者均确诊为颅内动脉瘤。常规正侧位DSA能显示存在动脉瘤病变或可疑存在动脉瘤,仅极少数病例能明确显示瘤颈形态(2/8)和载瘤动脉与瘤体的关系(1/8)。旋转DSA显示病变复杂结构的能力较常规DSA明显提高。8例血管三维重建处理的图像都清晰显示了脑动脉瘤瘤体、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,明显有助于提高对脑血管病变的诊断和治疗水平。 |

| Objective To evaluate the efficiency of rotational digital subtraction angiography (RDSA) and three dimensional (3D) reconstruction technique in cerebral angiography for intracranial aneurysms.Methods Eight cases of subarachnoid hemorrhage underwent conventional DSA, RDSA and angiographic 3D reconstruction. Effectiveness of each technique to show the aneurysm structure was compared.Results All patients were diagnosed as intracranial aneurysms via angiographic examination. Fine structures such as aneurismal neck and connected artery were difficult to identify on conventional DSA, whereas these details were shown marvelously clear by RDSA and 3D arterial reconstruction.Conclusion RDSA and 3D arterial reconstruction techniques are effective and useful in cerebral angiography, especially in diagnosing intracranial aneurysms. |
