Anomalous left internal mammary artery arising from an aberrant artery of the aorta in a patient with "pseudo bovine" aortic arch anatomy.

Many different aortic arch variants have been documented before. Pseudo bovine arch is the most common variant of the aortic arch. Pseudo bovine arch with other factors such as stenosis and calcification impose great difficulties even for experienced cardiologists. Knowledge of anatomical variants is useful information for interventional cardiologist, radiologist, and thoracic surgeons. Left vertebral artery left internal mammary artery (LIMA) alterations have been published a few times before, but here we present a first case to our knowledge with LIMA arising from an aberrant arterial branch of the aorta in a patient with a pseudo bovine aortic arch anatomy. <Learning objective: Variations of the aortic arch are due to alteration in the development of branchial arch arteries during embryonic period.
