RESUMEN
Subarachnoid-pleural fistula (SPF) is a rare complication of spine surgery with a transthoracic approach. The outcome of such an injury is affected by not only the pulmonary status due to the pleural effusion but also the neurological one, secondary to the intracranial hypotension. After reviewing the few published cases of SPF, the journey to diagnosis seams heterogenous and the management plan non-uniform. We report the case of a 48-year old women who underwent a right transthoracic discectomy that was complicated by an SPF. The diagnosis, although suspected perioperatively, was established with the gathering of an abundant post-operative pleural effusion, a subdural hematoma on head Computerized Tomography after drainage and Cerebro-Spinal Fluid markers present in the pleural fluid. The defect was effectively corrected with a radiological procedure. We compare our clinical and paraclinical findings and management plans to those reported in the few other published cases of SPF.
