Thoracic vertebrectomy and reconstruction using a microsurgical thoracoscopic approach.
A video-assisted thoracoscopic microsurgical approach was developed in the laboratory and subsequently used clinically to resect abnormalities of the thoracic vertebrae, to decompress the thoracic spinal cord, and to reconstruct the thoracic vertebral bodies. This report describes the development of the clinical operative techniques for microsurgical thoracoscopic vertebrectomy, neural decompression, and spinal reconstruction. This minimally incisional approach was clinically used in 17 patients to treat vertebral osteomyelitis, tumors, and compression fractures. Microsurgical thoracoscopic techniques were performed using several narrow, flexible, working portals placed in small incisions in the intercostal spaces. Access to the thoracic spine was achieved through the pleural cavity after temporary deflation of one lung using a double-lumen endotracheal tube. The parietal pleura, segmental vessels, and rib heads were dissected off the surfaces of the involved vertebrae to expose the region of interest. Long narrow spine dissection tools were used to perform the spinal decommpression and reconstruction. This technique achieved the same amount of spinal dissection as that achieved with conventional open spinal procedures and used microsurgical visualization techniques. The small incisions with reduced soft tissue dissection may reduce postoperative pain, shorten the length of hospitalization, and have cosmetic and functional advantages. Thoracoscopic vertebrectomies and reconstruction of the spine were technically feasilble procedures that were performed with excellent clinical results. This minimally incisional technique provides a viable alternative to thoracotomy or to posterolateral approaches for thoracic vertebrectomy and vertebral body reconstruction.
