Anomalous Origin of the Right Vertebral Artery from the Right Common Carotid Artery

Letter to the Editor Regarding “Anomalous Origin of the Right Vertebral Artery from the Right Common Carotid Artery”

“…In conclusion, the schematic illustration in Iwashita’s report 1) shows their misunderstanding of the concept of anomalous origin of the VA. An accurate or proper understanding of the embryology of VA is important for understanding the variations in the origin of the VA.…”

“…There are several misconceptions in the schematic illustrations by Iwashita et al 1) First, cervical SAs connect between the ICA (from the dorsal aorta) and VA, not the ECA. Furthermore, the lines and numbers between the ICA and the ECA are difficult to understand.…”

“…Dear Editor: I read with great interest a case report entitled "Anomalous Origin of the Right Vertebral Artery from the Right Common Carotid Artery" by Iwashita et al 1 recently published in JNET and would like to comment on the same. In this article, the authors reported a rare case of anomalous origin of the right vertebral artery (VA) and explained its embryological basis.…”

“…Iwashita et al 1 described that the right VA originating from the CCA was associated with an aberrant right subclavian artery (ARSA). However, recent studies reported a far lower incidence (9.8%-26%) of the right VA from the CCA with ARSA.…”
