Abstract
Dumbbell-shaped thoracic tumors usually involve the spinal canal and the posterior thoracic cavity. Gross total resection is the treatment of choice, but techniques for surgical excision remain controversial. An anterolateral transthoracic approach may remove the paravertebral component of the tumor, but has limited or no control of the intracanal lesion. A combined posteroanterior approach requires a 2-stage surgery with significant morbidity. The preferred approach depends mainly on the tumor location, size, shape, and its specific anatomical relationship with the surrounding vital structures. We present a surgical video of a single-stage posterior minimally invasive approach for the management of a thoracic dumbbell tumor.
