摘　　要：目的:通过影像学分析,探讨64排CT、CTA及DSA在颈动脉体瘤诊治中的作用。方法:自1998年以来我科收治的13例颈动脉体瘤患者,8例行DSA检查确诊,5例经64排CT及CTA检查确诊。9例在术前行DSA颈动脉及脑血管造影,观察并分析大脑动脉环及大脑侧支循环建立情况,6例在术前进行肿瘤滋养血管栓塞。结果:64排CT、CTA及DSA图像均显示颈动脉体瘤的特征性表现。64排CTA重建图像清晰,可直观、立体、多角度的显示肿瘤与颈内、外动脉的关系。而在球囊阻断患侧颈动脉,以观察颅内血管侧枝循环建立情况及栓塞肿瘤滋养血管方面DSA起着不可代替的作用。结论:64排CT、CTA及DSA诊治颈动脉体瘤具有重要的临床价值,可根据不同目的,选择不同的影像学检查方法。Objective： To evaluate the role of 64 - MSCT, CTA and DSA in the diagnosis of carotid body tumor. Methods： 13 patients with carotid body tumors were collected between January 1998 and December 2007, of whom 8 cases were checked by DSA, and 5 cases were checked by 64 - MSCT and CTA. The information of the Willis circle and cerebral collateral circulation of 9 cases were evaluated by DSA and the tumor′s feeding arterial vessels of 6 cases were embolized before operation. Results： 64 -MSCT, CTA and DSA all showed the common radiological features of carotid body tumors. The images performed by 64 - MSCTA were clear, direct and multi - angle on reflecting the relationship between tumor and carotid artery, while DSA was useful in temporary balloon occlusion of internal carotid artery and tumor′s feeding vessels embolization. Conclusion： 64 -MSCT, CTA and DSA all play an important role on the diagnosis of carotid body tumor, and different techniques are carried out according to the purpose.
