Thoracoscopic surgical resection of thoracic neurogenic tumors

Abstract

A video-assisted thoracoscopic microsurgical approach was performed to treat a myelopathic patient with a severe kyphotic deformity caused by chronic nonunion of compression fractures of T7-9 vertebrae. The kyphotic deformity was treated by combined operative procedures. First, an anterior release was performed using a thoracoscopic technique, sectioning the anterior longitudinal ligament and performing multilevel thoracic discectomies. Next, a posterior reduction and internal fixation of the deformity was achieved using hook-rod instrumentation. Finally, bone graft harvested during the posterior approach was used for interbody fusion via a thoracoscopic approach. Microsurgical thoracoscopic techniques potentially can be used in a variety of spinal surgeries. Compared to transthoracic and posterolateral approaches, this technique presents distinct advantages to treatment of anterior spinal pathology. The small incisions made into the intercostal spaces without retracting the ribs may reduce postoperative pain, shorten the length of hospitalization, and allow early return to activity. The operative techniques used in this case are described in detail. This report demonstrates that thoracoscopic discectomies and interbody fusion are technically feasible and can be effectively performed with acceptable results.
