行特殊血管检查致胸廓出口综合征诊断的假阳性率

False positive rate of special vascular examination of thoracic outlet syndrome

目的 研究健康人群中用于诊断胸廓出口综合征的特殊血管检查的阳性率的出现情况.方法 采用6种常用的特殊血管检查方法,对由健康人群中随机抽取的86名志愿者进行检查,并分性别和检查项目计算诊断为胸廓出口综合征的阳性率.结果 86名中51名出现检查阳性,阳性率为59.3％；其中32名出现一项阳性,阳性率为37.2％；11名出现二项阳性,阳性率为12.8％；6名出现三项阳性,阳性率为7.0％；2名出现四项阳性,阳性率为2.3％.结论 目前的特殊血管检查方法可能会导致错误诊断一些健康人群患有胸廓出口综合征.

Objective To investigate the occurrence of positive special vascular examination used in diagnosing thoracic outlet syndrome in the normal population.Mefhods Six types of commonly used special vascular screening methods were used in 86 randomly selected volunteers from the normal population.The positive rate of these tests in the male and female volunteers was calculated.Results Positive results were found in 51subjects.The positive rate was 59.3%.Thirty-two subjects had 1 positive test,the positive rate being 37.2%.Eleven subjects had 2 positive tests,the positive rate being 12.8%.Six subjects had 3 positive tests,with a positive rate of 7.0%.Two subjects had 4 positive tests,the positive rate being 2.3 %.Conclusion The special vascular examinations may lead to false diagnosis of thoracic outlet syndrome in normal people.
