摘　　要：目的观察侧面视角最佳计算方法(optimunmethodforprofileangleofsinght,Compas)技术对颅内动脉瘤的显示效果。方法搜集31例经CT扫描诊断为蛛网膜下腔出血的患者进行脑血管常规正、侧位造影和Campus技术采集后进行图像分析,比较Compas成像和常规正、侧位造影在显示动脉瘤方面的效果。结果通过Compas成像诊断为颅内动脉瘤23例,血管扭曲8例,23例动脉瘤均经手术证实。23例动脉瘤中5例正、侧位可显示动脉瘤颈部及载瘤动脉,18例正侧位造影血管边缘显示不规则,二者差异有统计学意义(χ2=14·93,P<0·05)。结论Compas可立体、直观完整地显示脑动脉瘤的病理解剖关系,对指导介入治疗、手术方式的选择、治疗效果的观察具有重要价值。Objective To evaluate the value of Compas technique( computed optimun method for profile angle of singht,Compas) in displaying intracranial aneurysms. Methods DSA images of 31 cases of subarachnoid hemorrhage diagnosed by CT were studied. The DSA images in routine A-P and Lateral projections were compared with the images obtained by Compas technique in the same equipment. Results 23 of 31 were diagnosed as intracranial aneurysms by Compas and confirmed by operation, while only 5 were diagnosed definitely with routine A-P & Lateral projections. The other 18 studies were discovered as blurred margin of the artery but indefinite for the diagnosis of aneurysms. There is a statistical difference between the two methods. χ~2=14.93,P<0.05. Eight of the 31 cases were distortion of the artery. Conclusion Compas can clearly display the shape and contour of intracranial aneurysms, which is very important for planning of therapy such as embolization or surgery, as well as follow-up after treatment.
