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。rrrrrrrrn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。rrrrrrrrn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；rrrrrrrrn6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。rrrrrrrrn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 deepen the understanding of the features of DSA in carotid body tumor and to discuss its value of diagnosis and interventional therapy. Methods Two experienced radiologists performed a retrospective analysis of 12 cases of aneurysms of DSA by double-blind method and then discussed together And reach a consensus. r r r r r r r r n Results DSA can confirm the diagnosis. In all patients, the bifurcation angle of the carotid artery increased and the internal and external carotid artery translocated. Most of the tumors were mainly from the external carotid artery and the blood supply was richer. r r n6 cases of patients surrounded by carotid artery visible local vascular invasion. In 2 patients, the range of tumor staining after embolization was narrowed, and the intraoperative bleeding was significantly reduced. Conclusions DSA is an effective method for the diagnosis and preoperative evaluation of carotid body tumors. Preoperative embolization helps to reduce intraoperative bleeding.
