RESUMO
Thoracotomy is used to approach and treat anterior spinal lesions arising from various causes. Between 1990 and 1997, we treated 56 patients (40 men and 16 women) between 14 and 67 years old (mean 38.4). All had spinal lesions that were impossible or difficult to reach by a posterior approach. Thirty-one (55.3%) had suffered spinal damage, 8 (14.3%) had spinal deformities, 7 (12.5%) had metastatic tumors, 5 (8.9%) had herniated discs, 4 (7.1%) had Pott's disease and 1 (1.8%) had osteolysis at D6. Thoracotomy was left-sided in 35 cases (62.5%) and right-sided in 19 (33.9%). Video-assisted thoracoscopy was used twice (3.6%). The level of incision was based on the site of the lesion, and the pleural cavity was opened in all cases except one. The posterolateral pleuro-diaphragmatic fold was dissected and the diaphragm opened for retroperitoneal access in 37 cases (66.1%) of thoracolumbar disease. Orthopedic treatment consisted of autologous bone grafts in all cases and placement of a Kaneda splint in 32 cases (57.1%). One patient had to undergo surgery a second time due to inappropriate placement of the vertebral splint. Pneumothorax occurred in one patient after removal of pleural drains. The incision became infected in one patient, and one case of ileal paralysis was observed. Overall, morbidity was 7.1%. We conclude that thoracotomy offers a good alternative approach to spinal lesions. Results are good and morbidity low.
