[Aortic vascular anomalies and Kommerell's diverticulum, an imagiologic diagnosis].
Aortic vascular anomalies are complex anatomic entities requiring often complex and problematic surgical approaches. The authors report the clinical case of a Kommerell's diverticulum and right-sided aortic arch. Right-sided aortic arch is an uncommon congenital defect of the aorta and it is rare in the setting of an otherwise normal heart. A right-sided aortic arch was described more than two centuries ago. Several classifications of these anomalies have been proposed on the basis of the arrangement of the arch vessels, relationships with the esophagus, or the presence of congenital heart anomalies. In the adult population, a right-sided aortic arch is often asymptomatic, unless aneurismal disease develops. This usually occurs at the level of the take-off of an aberrant left subclavian artery and is known as a Kommerell's diverticulum. In spite of its rarity, this condition is clinically relevant due to the mortality associated with rupture, morbidity caused by compression of mediastinal structures, and complexity of surgery.
