| 目的 分析比较27例锁骨下动脉盗血综合征(SSS)患者锁骨下动脉、椎动脉和桡动脉的血流动力学、频谱特点,以及狭窄程度与盗血的关系等。方法 27例患者均经临床检查、超声诊断以及相关检查确诊。彩色多普勒超声常规显示颈动脉、椎动脉、桡动脉、锁骨下动脉及无名动脉的内径、内膜和血流方向及速度。结果 27例患者中,锁骨下动脉狭窄18例,内径1.0~4.4 mm,血流速度100~420 cm/s;9例锁骨下动脉闭塞,均引起完全性盗血。椎动脉及桡动脉峰值血流速度患侧明显低于健侧,患侧椎动脉出现反向血流,桡动脉血流与锁骨下动脉狭窄程度和反向椎动脉血流有一定关系。结论 彩色多普勒血流显像(CDFI)可对完全性SSS做出诊断,部分性SSS可辅助于脉冲多普勒和束臂试验明确诊断。完全性和部分性盗血与血管狭窄程度有关。患侧椎动脉反向血流和桡动脉峰值血流速度取决于侧支循环建立的完善与否。 |

| Objective To analyze the hemodynamics, spectral characteristics of the subclavian, vertebral and radialis artery, and the relationship between the severity of stenosis and the steal degree in 27 patients with subclavian steal syndrome(SSS) by color Doppler flow imaging (CDFI). Methods Twenty-seven patients were diagnosed as SSS by clinic, CDFI and related physical examinations. The inside diameter and intima-media of carotid, vertebral, radialis, subclavian and innominate arteries were displayed with two-dimensional ultrasonography, and their blood flow velocity and direction were detected by CDFI. Results In the 27 patients with SSS, 18 patients had subclavian arterial stenosis with the inside diameter 1.0-4.4 mm and the velocity 100-420 cm/s. Occlusion of subclavian or innominate arteries were occurred in 9 patients and caused full SSS. The peak flow velocity of ipsilateral vertebral and radialis artery decreased significantly compared with the contralateral vertebral and radialis artery, and retrograde vertebral flow was also detected. There was an obviously relation between radialis artery flow and the severity of subclavian arterial stenosis as well as reverse vertebral flow in SSS. Conclusion The full SSS could be diagnosed by CDFI. Combining the CDFI and pulsed Doppler with tourniquet test, the partial SSS could be diagnosed. The full or partial SSS was dependent on the severity of stenosis. The peak flow of the ipsilateral vertebral artery and radialis artery was determined by collateral circulation. |
