Interventional bronchoscopy for benign tracheobronchial diseases under cardiopulmonary bypass support: case reports and literature review.

The use of cardiopulmonary bypass as an adjunct to airway surgery for non-malignant diseases in adults is not well established in the UK. We are reporting two cases which demonstrate the additional benefits of using cardiopulmonary bypass during difficult bronchoscopy and complex airway stenting. The first case presents an emergency indication for cardiopulmonary bypass in a life-threatening but benign condition. The second case presented, utilises cardiopulmonary bypass standby as adjunct to a potentially life threatening procedure. A review of the literature is also provided.
