Pulmonary torsion after cardiac surgery in two infants: review of pediatric literature.

Torsion of a lung or a lobe (LT) is a severe, sometimes life-threatening event that may occur spontaneously, after trauma, or after cardiac or thoracic surgery. The authors report on 2 prematurely born neonates who had LT after cardiac surgery. Both patients successfully underwent pulmonary lobectomy, which seems to be the best surgical approach. Given that careful anatomic unfolding of the lung and its reinflation under vision at the end of a cardiac or thoracic operation is deemed crucial to avoid LT, the authors suggest that, in case of a complete pulmonary fissure and/or free long bronchovascular pedicle, lobe fixation should be accomplished, too. Because of its rarity, we could find only 6 well-documented reports of LT diagnosed in children, whereas another 3 cases were quoted without clinical details. The pediatric literature is reviewed.
