Select and explain. 
A. Scalenectomy, B. Excision of a cervical rib, C. Thoracoplasty, D. First rib resection
C: Thoracoplasty
Answer: C: Thoracoplasty 
Explanation: Supraclavicular decompression of the thoracic outlet is the preferred operative approach for the thoracic outlet syndrome. This procedure consists of extensive anterior scalenectomy, middle scalenectomy, removal of a cervical rib (if present), and, on occasion, first rib resection. Transaxillary first rib resection has been widely used as well but is associated with a greater risk for complications.
