目的探讨二维彩超对血栓闭塞性脉管炎疾病临床价值，以期提高临床诊断水平。方法选取2010年4月~2013年4月76例血栓闭塞性脉管炎疾病患者为研究对象，均予二维彩超进行诊断，以CT血管成像作为金标准，观察二维彩超诊断符合率，并进行进行ROC曲线比较。结果二维彩超在动脉硬化或闭塞和CT血管成像诊断符合率为100%，二维彩超在动脉栓塞、血栓闭塞性脉管炎上和CT血管成像诊断符合率上比较差异无统计学意义(>0.05)。对二维彩超诊断血栓闭塞性脉管炎疾病进行ROC曲线比较，以血管内-中膜增厚正确率最高，为91.1%，其次是动脉血管“闪烁样”信号消失或减弱，为89.3%，血流速度增高正确率为86.8%，血管阻力增高正确率为88.4%，四者之间在正确率上比较差异无统计学意义(>0.05)。结论二维彩超是血栓闭塞性脉管炎疾病首选辅助检查方法，价值接近血管造影，是一种敏感、准确、方便的诊断方法。“,”Objective To investigate the clinical value of the two-dimensional ultrasound Buerger disease, in order to improve the clinical diagnosis. Methods April 2010 April 2013 76 patients with Buerger disease patients for the study, diagnosis herein are the two-dimensional ultrasound to CT angiography as the gold standard, to observe the two-dimensional ultrasound diagnosis rate, , and car ying out ROC curve comparison. Results The two-dimensional ultrasound in arteriosclerosis or occlusion and CT angiography diagnosis was 100%, two-dimensional ultrasound was no significant dif erence in the arterial embolism, Buerger on CT angiography and diagnostic accuracy ( >0.05). Two-dimensional ultrasound diagnostic Buerger disease ROC curve comparing to intravascular-right medial thickening highest rate of 91.1%, fol owed by arterial “flashes like” signal disappeared or weakened, 89.3% blood flow velocity increased 86.8% accuracy rate, vascular resistance increased accuracy was 88.4%, in the correct rate dif erence was not statistical y significant ( >0.05) between the four. Conclusion Two-dimensional ultrasound is Buerger disease prefer ed secondary screening method, the value of close to angiography is a sensitive, accurate and convenient diagnostic method.
