旋转DSA三维重建成像与常规DSA成像在动脉瘤瘤颈大小测量中的比较

The comparison of aneurysmal necks measured on three dimensional reconstruction images of rotational DSA and those of traditional DSA

目的探讨旋转DSA三维重建成像(3DDSA)在动脉瘤瘤颈大小测量中的价值,并与常规DSA(2DDSA)进行比较,为动脉瘤的栓塞提供更加丰富更加准确的信息。方法对在2DDSA检查中发现的14例动脉瘤的瘤颈进行常规测量,又分别将进行旋转血管造影和3DDSA成像后对动脉瘤的瘤颈进行测量。结果3DDSA与2DDSA在动脉瘤瘤颈的测量上存在一定的差异,3DDSA比较2DDSA在动脉瘤瘤颈的显示上有更多的角度显示的更加清晰,测量数据更加丰富。结论3DDSA比2DDSA能够显示动脉瘤更多的瘤颈,尤其是动脉瘤的最大颈,对介入手术具有重要的参考意义。

Objective To evaluate the value of three dimensional reconstruction images of rotational DSA on measuring aneurysmal necks and make a comparison with traditional DSA so as to provide more abundant and accurate informations for the enbolization of aneurysm. Methods A comparison was made between the measurement of aneurismal necks from 14 cases with traditional DSA examination and a measurement made on three dimensional reconstruction images of the same patient. Results There was a difference shown in the measurment of the aneurysmal necks between three dimensional reconstruction images of rotational DSA and those of traditional DSA, outcoming with more angles and data on three dimensional reconstruction images. Conclusions There are more angles of aneurysmal neck can be shown on rotational 3D DSA especially for the demonstration of the largest aneurysmal neck with a directional value for the intervention. （J Intervent Radiol, 2006, 15： 259-260）
