目的锁骨下动脉狭窄的临床症状与DSA改变的相关性。方法DSA证实锁骨下动脉狭窄28例,并把患者分为症状组18例及无症状组10例,分析两组患者的锁骨下动脉狭窄程度、侧支代偿与临床症状的关系。结果锁骨下动脉狭窄患者狭窄程度与临床症状无关,与侧支代偿有关。结论DSA能更好明确病变的程度和范围,评估侧支代偿,为临床诊断和治疗提供了的依据。
Objective To investigate the correlation between the clinical symptoms of subclavian artery stenosis and the changes of DSA. Methods DSA confirmed 28 cases of subclavian artery stenosis. The patients were divided into symptom group (n = 18) and asymptomatic group (n = 10). The degree of subclavian artery stenosis, collateral compensation and clinical symptoms were analyzed. Results The degree of stenosis in subclavian artery stenosis had no relation with clinical symptoms, and was related to collateral compensation. Conclusion DSA can better determine the extent and extent of lesion, assess the collateral compensation, and provide the basis for clinical diagnosis and treatment.
