Combination of Rare Right Arterial Variation with Anomalous Origins of the Vertebral Artery,Aberrant Subclavian Artery and Persistent Trigeminal Artery
A 32-year-old woman hospitalized for subarachnoid hemorrhage showed rare arterial variation on the right side with anomalous origins of the vertebral artery, aberrant subclavian artery and persistent trigeminal artery. Angiography showed the right vertebral artery to originate from the right common carotid artery, the right subclavian artery to arise separately from the descending aorta, and persistent trigeminal artery on the right side.
The possible embryonic mechanism of this previously unreported variant combination is discussed.
