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 The purpose is to study the relation between clinical symptoms and the repre-sentations of DSA in subclavian stenosis patients. Methods 18 Subjects with subclavian stenosis patients were confirmed by the examinations of DSA, and these patients were divided into two groups symptomatic group( 18 cases) and asymptomatic group (10 cases), the relation between clinical symptoms and the representations of DSA in subclavian stenosis patients was analysed. Results Clinical symptoms of subclavian stenosis patients were not related with severity of subclavian stenosis, but were related with collateral compensation. Conclusion DSA can help to define the location and severity of the subclavian stenosis lesion and can help to evaluate the colatteral compensation. Therefore.it turn out to be evidence in diagnosis and treatment of subclavian stenosis
