Aberrant Right Subclavian Artery with Kommerull Diverticulum

The presence of an aberrant right subclavian artery (arteria lusoria) is potentially the most important abnormality of the aortic arch. Aneurysmal dilatation (aberrant subclavian arterial aneurysms) of the proximal portion of the aberrant right subclavian artery can occur, a pouch-like aneurysmal dilatation is called Kommerell diverticulum. If the adjacent structures are compressed by this vessel, several symptoms can occur. In this article, we discuss the commercial diverticulum scenario. In this report, we discuss a case of kommerell’s diverticulum associated with an aberrant right subclavian artery in a pediatric patient.
