彩色多普勒超声在诊断锁骨下动脉窃血综合征中的应用价值

Color Doppler Ultrasound in the Diagnosis of Subclavian Steal Syndrome

目的分析多普勒超声诊断对锁骨下动脉窃血症的应用价值。方法通过总结35例临床患者多普勒超声影像学检查结果,对部分难以确诊患者使用CT、核磁共振等仪器进行确诊比较,以讨论彩色多普勒超声诊断在锁骨下动脉窃血症的运用价值。结果经诊断,患者右侧病变和左侧病变患者分别有11例和24例。狭窄情况为:轻度狭窄3例,中度狭窄15例,重度狭窄10例,动脉闭塞2例,无名动脉狭窄2例。有24例患者确诊为动脉粥样硬化,5例患者为多发性大动脉炎,2例患者为医源性左锁骨下动脉口狭窄,1例患者为外伤性右锁骨下动脉椎动脉开口近心侧损伤血肿压迫至狭窄。另外有3例患者在超声诊断中,超声诊断难以确诊,通过其他方法确诊。结论多普勒彩色超声技术对锁骨下动脉窃血症具有较高的诊断价值,值得临床推广应用。

Objective To analyze the application value of color Doppler ultrasound in the diagnosis of subclavian steal syndrome. Methods Doppler ultrasound imaging results of 35 patients were summarized, As for patients who were difficult to diagnose, CT and nuclear magnetic resonance instrument were used, in order to evaluate the value of color Doppler ultrasound in the diagnosis of subclavian steal syndrome. Results 11 patients were diagnosed with lesion at the right side and 24 patients were at the left side. 3 cases were diagnosed as mild stenosis, 15 cases as moderate stenosis, 10 cases as severe stenosis, 2 cases as arterial occlusion, and 2 cases as innominate artery stenosis. 24 patients were diagnosed as atherosclerosis, 5 patients with Takayasu arteritis, 2 patients with iatrogenic left subclavian artery stenosis, one patient with proximal injury hematoma compression stenosis of vertebral artery injury of right subclavian. The other 3 patients were difficult to diagnose with ultrasound and confirmed by other methods. Conclusions Color Doppler ultrasound is worthy of clinical application, as it＇s effective in the diagnosis of subclavian steal syndrome.
