Thoracic outlet neurovascular compression: approaches to anatomic decompression and their limitations.

Surgical management of thoracic outlet syndrome (TOS) has evolved to include multiple approaches for anatomic decompression. The relevant anatomy and review of different operative approaches are presented. The supraclavicular and transaxillary approaches are the most commonly used, and each has relative advantages. A working knowledge of these approaches and their limitations will aid in successful management of TOS.
