Abstract
Left bronchial compression is a rarely reported, postoperative complication of the
arterial switch operation with the LeCompte maneuver for transposition of the great
arteries. Postoperative neopulmonary root dilatation and the anterior-posterior, anatomical
relationship of the great vessels may cause this condition. Hypoxic pulmonary vasoconstriction
may mask the condition even if the left bronchus has been severely obstructed. The
apparent inconsistency between the abnormally decreased pulmonary blood flow and the
absence of any irregularities in the vascular structure that might account for it
suggested hypoxic pulmonary vasoconstriction to be the cause. We present herein a
case of left bronchial compression presenting malacia after an arterial switch operation
with the LeCompte maneuver and also present a review of seven, other, reported cases.
Learning objectives
Left bronchial compression is a rare complication of the arterial switch operation
with the LeCompte maneuver for transposition of the great arteries and is possibly
caused by root dilatation and the anatomical relationship of the great vessels. Hypoxic
pulmonary vasoconstriction may mask the condition.
