Abstract
Cardiovascular variations are very common and often without consequences for the individual. One could expect that variations
in larger vessels such as the translocation of the subclavian artery result in some kind of symptoms, but it is often only found
incidentally during unrelated medical examinations not related to it or during anatomical dissections in educational settings.
Here we present two cases of a translocated right subclavian artery, which is commonly called aberrant right subclavian
artery or arteria lusoria. Both donors lived their entire lives with the condition remaining undiagnosed before the dissection
during a medical anatomy course setting. We describe the course of the artery and associated other anomalies as found in the
donors and discuss the developmental causes of the observed variations. Additionally, we point out why a thorough evaluation
of any patient is important before operations in the neck or thoracic cavity given the potential presence of an aberrant right
subclavian artery.
