颈动脉体瘤少见,临床常易误诊。本文应用彩色多普勒超声技术诊断6例颈动脉体瘤,均经病理证实,现报道如下。 资料与方法 本组6例中男4例,应用美国HP77020AC型彩超仪观察患侧颈动脉分叉处二维结构,确定瘤体与动脉之间的关系,观察彩色血流显示情况,并在其引导下测定颈动脉分支和瘤体内血循环状况。 结果 从二维结构看,6例颈动脉体瘤均位于颈动脉分歧部(图1),表面光滑,边界清晰,内部多表现为中强点状回声,夹杂着管状及小片状液性暗区 Carotid body tumors are rare and often misdiagnosed in clinical practice. In this paper, color Doppler ultrasonography was used to diagnose 6 cases of carotid body tumors, all of which were confirmed by pathology and are reported as follows. Materials and Methods In this group of 6 males and 4 males, the two-dimensional structure of the ipsilateral carotid bifurcation was observed with a US-based HP77020 AC colorimeter, the relationship between the tumor and the artery was determined, and the color flow display was observed. Under the guidance of the determination of carotid artery branch and tumor blood circulation. Results From the two-dimensional structure, 6 cases of carotid body tumors are located in the different parts of the carotid artery (Figure 1), the surface is smooth, the boundary is clear, the internal manifestation of multiple strong point echoes, mixed with tubular and small liquid droplets Area
