目的探讨颈动脉体瘤的数字减影血管造影（ＤＳＡ）诊断、鉴别诊断及制订治疗方案的价值。方法总结１１例经手术病理证实的颈动脉体瘤，研究ＤＳＡ表现，并与其它颈部肿块病变进行对照。结果ＤＳＡ能清楚显示颈动脉体瘤血管及与相邻血管的关系。颈总动脉分叉开大呈握球状，枕动脉近段向前上推压移位，咽升动脉肿瘤中心供血具有特征性。恶变者有明显的恶性肿瘤ＤＳＡ特征。结论颈动脉体瘤的ＤＳＡ特征明显，影像直观，血管关系明确，对诊断与鉴别诊断及制订治疗方案有不可替代的作用。
Objective To investigate the value of digital subtraction angiography (DSA) in the diagnosis, differential diagnosis and treatment of carotid body tumor. Methods 11 cases of carotid body tumor confirmed by surgery and pathology were studied, and the manifestations of DSA were studied and compared with those of other cervical masses. Results DSA can clearly show the relationship between carotid body tumor vessels and adjacent blood vessels. The common carotid bifurcation was grasped globular, the proximal segment of the occipital artery pushed upward and downward, and the blood supply to the pharyngeal ascending aorta tumor center was characteristic. Malignant tumors have obvious characteristics of DSA. Conclusion The carotid body tumor has obvious DSA features, visual images and clear blood vessels relationship, which plays an irreplaceable role in diagnosis and differential diagnosis and treatment planning.
