Left bronchial compression after an arterial switch operation with the LeCompte maneuver for transposition of the great arteries: A case report and literature review

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.
