Cardiopulmonary complications during anaesthesia and surgery for severe thoracic lordoscoliosis.

Abstract

A 15-year old girl underwent a posterior spinal fusion procedure for severe lordoscoliosis. On turning to the prone position acute posture-related upper airway obstruction occurred. During surgery, manipulation of the spine caused several episodes of loss of cardiac output. Retrospective assessment of the pre-operative chest X rays demonstrated approximation of the sternum and thoracic vertebrae, with evidence of tracheal narrowing at the level of the thoracic inlet. We feel that both complications were directly related to the severity of the lordoscoliosis and that careful pre-operative clinical, spirometric and X ray assessment should be undertaken in such patients.
