目的:探讨颈动脉体瘤的超声声像学特点,提高其超声诊断准确率。方法:回顾性分析7例颈动脉体瘤患者的超声声像图资料,并与CT检查结果对照分析。结果:颈动脉体瘤超声表现为颈动脉分叉处实性低回声团块,颈内外动脉分叉角度可出现不同程度增大,瘤内血液供应丰富,可见动脉血流信号。CT表现为软组织肿块,密度均匀,增强表现为均匀性强化。结论:超声有助于颈动脉体瘤的诊断,且可明确瘤内血液供应与周围血管的关系,指导手术方案的制订、手术入路的选择。
Objective: To investigate the ultrasonographic features of carotid body tumor and improve the diagnostic accuracy of ultrasonic diagnosis. Methods: The echocardiographic data of 7 patients with carotid body tumor were retrospectively analyzed and compared with CT examination results. Results: Carotid body tumor showed low echo mass in the bifurcation of carotid artery. The bifurcation angle of internal carotid artery and internal carotid artery increased with different degrees. The blood supply of tumor was rich, and the arterial blood flow signal was visible. CT showed soft tissue mass, uniform density, enhance the performance of enhanced uniformity. Conclusion: Ultrasound is helpful for the diagnosis of carotid body tumor, and it can make clear the relationship between the blood supply of the tumor and the surrounding blood vessels, guide the development of the surgical plan and the choice of surgical approach.
