We studied 165 cases of thoracic-outlet syndrome in 142 patients in whom resection of the first rib had been performed. In seventy-three cases (44 per cent), there was compression of a nerve distally, as shown by electromyography and conduction studies. The most common secondary compression was carpal tunnel syndrome (forty-one cases). Thirteen patients needed an operation at three sites or more. Our results show that proximal compression of a nerve lessens its ability to withstand more distal compression. Once the diagnosis of thoracic-outlet syndrome has been made, the possibility of an additional distal compression neuropathy should be investigated.
我们研究了142例接受第一肋切除术的患者中的165例胸廓出口综合征病例。在73例（44%）病例中，肌电图和传导研究显示神经在远端受到压迫。最常见的继发性压迫是腕管综合征（41例）。13例患者需要在三个或更多部位进行手术。我们的结果表明，神经近端受压会降低其承受更远端压迫的能力。一旦诊断出胸廓出口综合征，就应调查是否存在额外的远端压迫性神经病变。
