Multidetector CT Scan Findings of a Right Aberrant Retroesophageal Vertebral Artery With an Anomalous Origin From a Cervical Aortic Arch.
Summary of "Multidetector CT Scan Findings of a Right Aberrant Retroesophageal Vertebral Artery With an Anomalous Origin From a Cervical Aortic Arch."
Various malformations of the aortic arch and great vessels have been reported in the literature, which reflects the complexity of their embryologic development. Most of them are of incidental finding and remain asymptomatic but can be responsible for respiratory or digestive symptoms and be associated with congenital cardiac diseases. We report the case of a patient presenting a right retroesophageal vertebral artery. This malformation was associated with multiple anomalies of the aortic arch. We report a classification of the most common aortic arch abnormalities by recalling Edwards double aortic arch model and embryologic variants. Here, we report on the rare case of a right retroesophageal vertebral artery. We assimilate this malformation to a vertebral arteria lusoria and attribute it to the lack of caudal migration of the fourth branchial arch, responsible for a left cervical aortic arch with an interruption between the right subclavian and vertebral arteries.

Medical and Biotech [MESH] Definitions
Vertebral Artery Dissection
Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
Vertebral Artery
The first branch of the SUBCLAVIAN ARTERY with distribution to muscles of the NECK; VERTEBRAE; SPINAL CORD; CEREBELLUM; and interior of the CEREBRUM.
Basilar Artery
The artery formed by the union of the right and left vertebral arteries; it runs from the lower to the upper border of the pons, where it bifurcates into the two posterior cerebral arteries.
Internal Mammary-coronary Artery Anastomosis
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Laminectomy
A surgical procedure that entails removing all (laminectomy) or part (laminotomy) of selected vertebral lamina to relieve pressure on the SPINAL CORD and/or SPINAL NERVE ROOTS. Vertebral lamina is the thin flattened posterior wall of vertebral arch that forms the vertebral foramen through which pass the spinal cord and nerve roots.
