Abstract
BackgroundAn aberrant right subclavian artery which arises from the proximal descending aorta may result in aortic dissection. The dissection may occur at either the site of the primary intimal tear or from an aortic branch. These conditions may lead to blood flow limitation and possible aneurysmal degeneration in the future.Case presentationWe described the clinical presentation and management of a 54-year old patient diagnosed with a rare case of an aberrant right subclavian artery with Stanford Type B aortic dissection. A hybrid surgical approach was successfully performed and the patient had an uneventful recovery.ConclusionEven though aortic dissection is often an incidental finding, this case highlighted that in rare situations, it can be associated with an aberrant right subclavian artery. It is important to disseminate this association as it has profound diagnostic and therapeutic implications in safeguarding the clinical outcomes of patients with such condition.
Highlights
An aberrant right subclavian artery which arises from the proximal descending aorta may result in aortic dissection
Among the various types of anatomic variations associated with the aortic arch, an aberrant right subclavian artery (ARSA) is the most frequently encountered
As high as 60% of the ARSA patients may suffer from aneurysmal dilatation that may lead to Kommerell’s diverticulum (KD), a condition frequently associated with an increased risk of rupture and dissection [2]
Summary
An aberrant right subclavian artery which arises from the proximal descending aorta may result in aortic dissection. The dissection may occur at either the site of the primary intimal tear or from an aortic branch These conditions may lead to blood flow limitation and possible aneurysmal degeneration in the future. Case presentation: We described the clinical presentation and management of a 54-year old patient diagnosed with a rare case of an aberrant right subclavian artery with Stanford Type B aortic dissection. There are very few reported cases of ARSA patients complicated with acute type B aortic dissection who were not diagnosed with a KD. Our patient in this case report was one of such rare cases.
