Aberrant right subclavian artery (arteria lusoria) aneurysm with a Kommerell’s diverticulum

Abstract

The treatment options for aberrant right subclavian artery vary depending on the presence of Kommerell’s diverticulum. Because there is a tendency not to report mortalities of these rare cases in the literature, it is hard to reach a conclusion on treatments from the limited data on post-interventional results in these patients. We report our experience with a 67-year old patient with an aberrant right subclavian aneurysm with Kommerell’s diverticulum, diagnosed by chance.

Aberrant right subclavian artery: case report and literature review

“…Along its course, an ARSA may cross the aortic arch transversely, posterior to the esophagus and the trachea in the direction of the right arm (in 80% of cases), anterior to the trachea (in 5% of cases), or even between the esophagus and the trachea (in 15% of cases), following a more linear path than the normal right subclavian artery. 16 , 17 , 18 , 19 …”
