Abstract
in English, French

The arterial switch operation is the gold-standard treatment for dextro-transposition of the great arteries. Long-term follow-up data are beginning to reveal its natural history and associated late complications, including various reoperations for those complications. Given the unique anatomy and the increasing longevity of these patients, there is a need for effective surgical repair options to address aneurysmal and degenerative changes in both neoaortic and pulmonic roots. Thereby, we describe our technique and the novel considerations for prosthetic choice with reconstruction of both the neoaortic root and pulmonary artery, with satisfactory postoperative results.

La détransposition artérielle constitue le traitement de référence dans les cas de dextro-transposition des gros vaisseaux. De nouvelles données, issues du suivi à long terme, nous permettent de mieux comprendre l’évolution naturelle à la suite de cette intervention et les complications tardives qui y sont associées, y compris les diverses interventions à réaliser pour les corriger. Étant donné les caractéristiques anatomiques uniques de ces patients et l’augmentation de leur espérance de vie, il est nécessaire de proposer des options efficaces de réparations chirurgicales pour remédier aux changements anévrismaux et dégénératifs des racines néoaortique et pulmonaire. Ainsi, nous décrivons la technique que nous avons utilisée et les nouveaux éléments qui entrent en ligne de compte dans le choix d’une prothèse pour une reconstruction de la racine néoaortique et de l’artère pulmonaire, avec des résultats postopératoires jugés satisfaisants.
