摘　　要：目的探讨中度以上狭窄锁骨下动脉窃血综合征（SSS）颅内外动脉侧支循环方式及血流动力学的变化。方法选择中度以上狭窄SSS患者18例，应用彩色多普勒超声分别观察其颅内外动脉的彩色血流方向，并行频谱形态分析。结果13例患侧颅内外椎动脉双向血流（其中包括6例基底动脉双向血流），5例患侧颅内外椎动脉反向血流（其中包括1例患侧大脑后动脉的P1段和基底动脉反向血流、2例患侧大脑后动脉的P1段双向和基底动脉反向血流）。结论SSS患者具有三种颅内外动脉侧支循环途径，彩色多普勒超声能准确、实时评价SSS血流动力学改变。Objective To observe collateral pathways and hemodynamic changes of the intracranial and extracranial arteries in patients with subclavian steal syndrome（SSS） in moderate artery stenosis. Methods A total of 18 patients with SSS were selected. Their intracranial and extracranial arterial blood flow direction was observed, and their spectrum were analyzed with color Doppler ultrasonography. Results Among of the 18 cases, bidirectional blood flow of the involved vertebral artery （VA） developed in 13 patients [including bidirectional blood flow of basilar artery（BA） in 6 patients], reversed blood flow of involved VA in 5 patients（including reversed blood flow of PI segement of involved posterior cerebral artery and BA in 1, bidirectional blood flow of P1 segement of involved posterior cerebral artery and reversed BA in 2）. Conclusions There are three collateral pathways of the intracranial and extracranial arteries in patients with SSS. Color Doppler ultrasonography can real-time detect the intracranial and extracranial arterial hemodynamic changes in these patients.
