We examined the usefulness of color-coded Doppler echography for evaluating hemodynamics in patients with subclavian steal syndrome. Eighteen patients with subclavian steal syndrome, aged 54 to 77 years, were investigated. The diagnosis was confirmed by conventional angiography and pulsed-wave Doppler sonography. Using color-coded Doppler echography, the common, internal and external carotid and vertebral arteries and the subclavian artery on the affected side were visualized. In all patients, color-coded images of the antegrade common carotid arterial flow and the retrograde vertebral arterial flow on the affected side were obtained. Rapid flow through stenotic lesions and reflux from vertebral to subclavian arteries at the vertebral arterial ostia were observed. Color-coded Doppler echography is superior to duplex echography without the color-coded mode, because the flow through the affected vertebral and subclavian arteries can be easily traced in detail and the images are persuasive. This method is beneficial for diagnosing subclavian steal syndrome.
我们研究了彩色编码多普勒超声心动图在评估锁骨下动脉盗血综合征患者血流动力学方面的实用性。对18例年龄在54至77岁之间的锁骨下动脉盗血综合征患者进行了研究。诊断通过传统血管造影和脉冲波多普勒超声检查得以证实。使用彩色编码多普勒超声心动图，可观察到患侧的颈总动脉、颈内动脉、颈外动脉、椎动脉以及锁骨下动脉。在所有患者中，均获取了患侧颈总动脉正向血流和椎动脉逆向血流的彩色编码图像。观察到狭窄病变处血流快速通过，以及椎动脉开口处从椎动脉到锁骨下动脉的血液反流。彩色编码多普勒超声心动图优于无彩色编码模式的双功超声心动图，因为通过患侧椎动脉和锁骨下动脉的血流能够轻松详细地追踪，且图像具有说服力。该方法有助于诊断锁骨下动脉盗血综合征。
