Endoscopic-assisted Infraclavicular Approach for First-Rib Resection in Neurologic Thoracic Outlet Syndrome: A Report of Two Cases.

Various reported surgical approaches for the treatment of thoracic outlet syndrome (TOS) exist and no firm evidence exists for any approach. A 16-year-old and a 29-year-old male presented with numbness in the upper limb. Neurologic TOS was diagnosed, and surgery was planned for the resection of the first rib and scalene muscles. Through an infraclavicular incision, open resection of the anterior scalene muscle and the anterior aspect of the first rib was performed. With the assistance of endoscopy, the middle scalene muscles and the posterior aspect of the first rib were resected. Preoperative symptoms improved after surgery without any complications. The endoscopic-assisted infraclavicular approach enabled resection of the first rib and scalene muscles, leading to satisfactory outcomes. Level of Evidence: Level V (Therapeutic) [ABSTRACT FROM AUTHOR]
