A Rare Complication of Thoracic Spine Surgery: Pediatric Horner's Syndrome after Posterior Vertebral Column Resection-A Case Report.

Pediatric HS after posterior instrumented scoliosis correction surgery with posterior vertebral column resection of the thoracic spine is very rare. This is the first reported case of HS after posterior vertebral column resection and spinal fusion for congenital kyphoscoliosis without the use of epidural analgesia. Symptom resolution may be variable and, in some cases, delayed.
