- Abstract
Objective: To investigate the ultrasonographic characteristics of the hemodynamic changes of the contralateral vertebral artery (VA) in patients with different types of subclavian steal syndrome (SSS). Methods: A total of 152 cases of SSS diagnosed by carotid Doppler ultrasonography (CDU) and confirmed by CT angiography (CTA) were enrolled as the study group. The 152 cases of SSS were divided into type I (47 cases of occult steal blood),type II (60 cases of partial steal blood) and type III (45 cases of complete steal blood).Meanwhile,46 cases of cardiovascular and cerebrovascular diseases were excluded from the health examination center as the control group. The diameter and hemodynamic changes of VA in healthy side of patients with different types of steal blood were analyzed and compared with the control group. Results: The hemodynamic parameters of VA on the contralateral side of three types of SSS in the study group were compared with those in the control group, there was no significant difference between type I and the control group (P>0.05), and there was significant difference between type II and type III and the control group (P<0.05);The diameter and hemodynamic parameters of VA increased with the severity of steal blood (P<0.05). Conclusion: CDU examination of VA hemodynamic parameters in healthy side of SSS patients can be used to preliminarily evaluate SA lesions and VA-VA steal pathway.
