目的:探讨彩色多普勒超声诊断锁骨下动脉盗血综合征的价值及诊断方法。方法:对40例锁骨下动脉盗血综合征患者利用彩色多普勒超声仪进行诊断,并观察这些部位的超声表现以及血液动力学变化情况,并和DSA的诊断结果进行比较。结果:这40例患者都是动脉粥样硬化原因引起的病症。利用彩色多普勒超声仪,来诊断40例锁骨下动脉盗血综合征患者,其中33例患者锁骨下动脉起始部位狭窄,2名患者无名动脉狭窄,而Ⅰ级盗血患者一共有13例,Ⅱ级盗血患者有17例,Ⅲ级盗血患者10例。和DSA结果相比,准确率达到了98%左右。结论:临床上在诊断锁骨下动脉盗血综合征时,可以利用彩色多普勒超声仪进行诊断,该诊断方法是一种有效的诊断方法,能够有效的分析、评价锁骨下动脉盗血综合征患者的血液动力学变化情况。
Objective: To investigate the value and diagnosis of color Doppler ultrasound in the diagnosis of subclavian steal syndrome. Methods: Forty cases of subclavian steal syndrome were diagnosed by color Doppler sonography. The sonographic findings and hemodynamic changes were observed and compared with those of DSA. Results: All 40 patients were caused by atherosclerosis. Forty cases of subclavian steal syndrome were diagnosed by color Doppler sonography. Thirty-three patients had a stenosis of the subclavian artery and two had unnamed arterial stenosis. Thirteen patients , 17 cases of grade Ⅱ steal patients, 10 cases of grade Ⅲ steal patients. Compared with the DSA results, the accuracy rate reached about 98%. Conclusion: Clinic diagnosis of subclavian steal syndrome can be diagnosed by color Doppler ultrasound, which is an effective diagnostic method to effectively analyze and evaluate subclavian steal syndrome Hemodynamic changes in patients.
