Case Report (n=1)
This case highlights a rare presentation of acute type B aortic dissection occurring in the setting of complex anomalous aortic arch anatomy.
Alerts clinicians to arch anomalies in acute type B dissection; extends sparse case reports but leaves open causal risk.
A 48-year-old man presented to the emergency department with acute onset of back pain and left leg numbness and weakness. Computed tomography angiography (CTA) revealed an acute type B aortic dissection in the setting of anomalous aortic arch anatomy. From proximal to distal, the patient had a common origin of bilateral carotid arteries, a left subclavian artery giving rise to a dominant vertebral artery, and an aberrant right subclavian artery that was dissected from its origin to the level of the right shoulder (A).
