Thoracoscopic correction of a congenital persistent right aortic arch in a young cat

Abstract
in English, French

A 9-week-old kitten was diagnosed with a congenital vascular ring anomaly by means of an esophageal contrast study. At 6 mo of age, a non-selective vascular study was used to diagnose a persistent right aortic arch (PRAA). Left-sided thoracoscopic surgery was performed, using a Liga-Sure vessel sealant device to seal and transect the ligamentum arteriosum.

Correction par thoracoscopie d’une crosse aortique droite congénitale persistante chez un jeune chat. Un chaton âgé de 9 semaines a été diagnostiqué avec une anomalie congénitale d’anneau vasculaire à l’aide d’un examen œsophagien en contraste. À l’âge de 6 mois, une étude vasculaire non sélective a été utilisée pour diagnostiquer une crosse aortique droite persistante (PRAA). Une chirurgie par thorascopie du côté gauche a été réalisée à l’aide d’un dispositif de scellage des vaisseaux Liga-Sure pour sceller et couper transversalement le ligamentum arteriosum.
