Magnetic Resonance Angiographic Demonstration of Unusual Duplication of Left Vertebral Artery

Anomalous Origin and Course of Right Vertebral Artery With Aberrant Right Subclavian Artery

Origin and course anomalies of the vertebral arteries are rare. They are considered a congenital anomaly that occurs in the early stages of embryonic development. Thanks to magnetic resonance angiography, these anomalies can be diagnosed easily. Detecting these anomalies is especially important before endovascular interventional procedures. In this case report, we present magnetic resonance angiography findings of a patient with extraforaminal vertebral artery that originated from right common carotid artery and also with aberrant right subclavian artery.

Anomalous triple origin and neck mergers of a vertebral artery

Accurate knowledge of the variant origin of the vertebral arteries (VAs) is important in vascular surgery and angiographic procedures in the neck. A triple origin of the VA is extremely rare. We report the first adult case of triple origin of the right VA from the right subclavian artery (SA). This report demonstrates magnetic resonance (MR) angiography findings of this unusual anatomic variation .
