摘要
目的 加深对颈动脉体瘤DSA表现特点的认识，探讨其诊断与介入治疗价值。方法 由两名有经验的放射学医师按双盲法对12例动脉体瘤的DSA造影资料进行回顾性分析，然后共同讨论并达成一致意见。结果 DSA均能明确诊断。所有患者均见颈动脉分叉角度增大，颈内、外动脉移位；大部分瘤体以颈外动脉供血为主，血供较丰富；6例患者瘤体包绕颈动脉者可见局部血管受侵。2例患者栓塞后造影见肿瘤染色范围缩小，且术中出血明显减少。结论 DSA是颈动脉体瘤的诊断和术前评估的有效手段。术前栓塞有利于减少术中出血。
Objective: To make a further understanding of the DSA features of the carotid body tumor (CBT) and to explore the clinical value of DSA diagnosis and interventional treatment for CBT. Methods: Twelve cases of CBT with DSA data were analyzed retrospectively. The DSA appearances in all of the patients were observed dynamically in a double blind manner by two experienced radiologists together and a consensus interpretation formed. Results: DSA could establish definitive diagnosis in all cases. The DSA features of the CBT were: the increase of bifurcation angles of internal and external carotid arteries in all cases; the CBT supplied by external carotid arteries in most cases and the significant increase of tumor vessels in bifurcation; invasion of internal or external carotid arteries in 6 cases. The tumor staining disappeared mostly after the supplying arteris were embolized in 2 cases, and the bleeding during the operation reduced significantly. Conclusion: The DSA is useful in the diagnosis of the CBT and for therapeutic planning. The pre-operation embolization of the CBT contributes to reduce the bleeding during operation.
