Sibson筋膜导致胸廓出口综合症

Thoracic Outlet Syndrome Induced by Sibson'sFascia

本文分析了1987～1995年手术治疗45例胸廓出口综合症病人，经手术证实引起胸廓出口综合症之主要病因中除通常所述的斜角肌病变、预肋、胸小肌出点处病变和肋锁间隙病变外。还有一种病因，即胸膜上筋膜（Sibson筋膜）卡压臂丛下干而导致胸廓出口综合症。其中7列行手术探查肘，未发现其他卡压因素，仅发现臂丛下手表面覆盖一层薄的筋膜，遂对此筋膜进行了松解，术后症状明显缓解，因此认为此膜系卡压因素。

45 cases of thoracic outlet syndrome were treatedwith operation and analysed from l987 to 1995. The main causes of thoracic outlet syndrome were demonstrated with operation that in addition to the commonly mentioned cervical rib, pathological changes of scalene muscle, pectoral muscle and costoclavicular space, there was a kind of etiology, i. e. the thoracic outlet syndrome was induced by iong time compression of suprapleural fascia (Sibaon's fascia) on the inferiortrunk of brachial plexus. In the process of operativeexploration, it was found in seven cases that only a thinlayer of fascia covered over the inferior trunk of brachialplexus, without any other factor of long compression. Asthis fascia had been relaxed, the syndrome wassignificantly eliminated. Therefore, it was considered thatthis fascia is a factor for long compression.
