目的分析颈动脉血栓超声特点及其与动脉硬化斑块的鉴别诊断。方法颈部动脉超声检查的患者41417例,颈动脉血栓患者行CT或MRI检查,并超声随访。结果41417例中,检出血栓870例,检出率2.10%。其中血栓呈无回声2例,低回声393例,等回声195例,混合回声280例。附壁血栓9例,血栓性闭塞或近闭塞42例,颈动脉硬化斑块合并血栓性闭塞或近闭塞819例。颈动脉血栓和血栓合并斑块的男性患者均较女性患者少,附壁血栓组和血栓性闭塞组的患者年龄较血栓合并斑块组小,差异均有统计学意义(P<0.01)。结论超声检查可以用于颈动脉血栓的诊断,并与颈动脉硬化斑块鉴别,为临床的诊治提供依据。
Objective To analyze the characteristics of carotid artery thrombosis and its differential diagnosis with atherosclerotic plaque. Methods 41,417 patients with carotid artery ultrasonography were examined. The patients with carotid artery thrombosis were examined by CT or MRI and followed up by ultrasound. Results 41417 cases, 870 cases of thrombus detected, the detection rate of 2.10%. Among them, thrombus showed no echo in 2 cases, hypoechoic in 393 cases, equivalent echoes in 195 cases, mixed echoes in 280 cases. 9 cases of mural thrombus, 42 cases of thrombotic occlusion or occlusion, 819 cases of carotid atherosclerotic plaques with thrombotic occlusion or occlusion. The number of male patients with carotid artery thrombosis and thrombus with plaque was less than that of female patients. The age of patients in the group of mural thrombus and thrombus occlusion was smaller than that of the thrombotic plaque group (P <0.01). Conclusion Ultrasound can be used for the diagnosis of carotid artery thrombosis, and carotid atherosclerotic plaque identification, provide the basis for clinical diagnosis and treatment.
