【关键词】  常规DSA;旋转DSA;血管成像;颅内动脉瘤
[摘要] 目的:探讨旋转数字减影血管造影(RDSA)在颅内动脉瘤成像中的应用。方法:对疑有颅内动脉瘤的43例患者首先进行常规DSA检查,对其中27例进行RDSA检查,研究RDSA的技术参数及应用价值。结果:43例中,16例常规DSA能清楚显示,其余27例在常规DSA基础上加RDSA,动脉瘤的形态、位置及毗邻关系得到清楚显示。结论:常规DSA是诊断颅内动脉瘤的必要检查方法,RDSA是常规DSA的重要补充,对颅内动脉瘤的成像、治疗及复查有重要的价值。

Method of Study of Rotational DSA in Intracranial Aneurysms
Abstract:Objective To explore the application of rotational DSA(RDSA)inintracranial Conventional DSA were performed in 43 patients with suspected intracranial aneurysms,27 cases examined by rotational DSA,the technical parameter and application value were In the 43 cases,16 cases were clearly displayed by conventional DSA,the rest (27cases)by conventional DSA and rotational DSA,the appearance、location、adjacency relationship were displayed Rotational DSA is important supplement of conventional DSA and it have important value of image、therapy and check to intracranial aneurysms.
Key words:Conventional DSA;Rotational DSA;Angiography;Intracranial aneurysms
近年来,数字减影血管造影(DSA)技术作为诊断颅内动脉瘤最真接、最可靠的方法广泛应用于临床,为克服常规DSA影像中动脉瘤与周围血管重叠的问题,人们采用了旋转DSA(RDSA),能更清楚的显示颅内动脉瘤及其毗邻关系,是常规DSA的重要补充。
1 材料与方法
一般资料搜集本院2004年1月至2006年3月经CT和(或)腰穿证实为蛛网膜下腔出血,临床疑为颅内动脉瘤的病例43例,男24例,女19例,年龄29岁~72岁,。对所有43例患者首先进行常规DSA检查,对其中27例进行RDSA检查。
设备及成像方法使用西门子AXIOMArtis dTA大平板DSA系统
