Angiographic studies were performed on 60 of 394 patients diagnosed as having thoracic outlet syndrome. Ten of the patients studied angiographically presented with obstruction of contrast material in the axilla with refilling of the axillary artery through the external mammary and shoulder arteries. The obstruction was caused by lower trunk brachial plexus compression. This seldom known cause of hyperabduction syndrome occurred in 2.5 per cent of the patients examined for thoracic outlet syndrome. Surgical treatment consists of loosening the axillary artery by tying off the external mammary and circumflex arteries, followed by section and anastomosis of the axillary artery anteriorly to the brachial plexus. Angiography is considered a basic diagnostic procedure, mainly when concomitant compression occurs and gives good dynamic information on the location and importance of the compression.
对394例诊断为胸廓出口综合征的患者中的60例进行了血管造影研究。经血管造影研究的患者中有10例出现腋窝造影剂阻塞，腋动脉通过胸外侧动脉和肩胛动脉重新充盈。阻塞是由臂丛下干受压引起的。这种很少为人所知的过度外展综合征病因在接受胸廓出口综合征检查的患者中占2.5%。手术治疗包括结扎胸外侧动脉和旋肱动脉以松解腋动脉，然后将腋动脉在臂丛前方切断并吻合。血管造影被认为是一种基本的诊断方法，主要用于存在合并压迫的情况，并能提供有关压迫部位和严重程度的良好动态信息。
