Abstract

We read with interest the letter “Common Origin of Brachiocephalic and Left Common Carotid Arteries: Proposal of New Terminology.”[1][1] The authors describe the variations in the origins of arch vessels, including the common origin of the brachiocephalic trunk and left common carotid artery,

Highlights

We read with interest the letter “Common Origin of Brachiocephalic and Left Common Carotid Arteries: Proposal of New Terminology.”[1]
The most common variation in aortic arch branching seen is the common origin of brachiocephalic trunk and left common carotid artery commonly called the “bovine arch.”
The aortic arch in cattle gives rise to a large trunk, which gives off a bicarotid trunk and both subclavian arteries

Summary

Introduction

We read with interest the letter “Common Origin of Brachiocephalic and Left Common Carotid Arteries: Proposal of New Terminology.”[1]. The most common variation in aortic arch branching seen is the common origin of brachiocephalic trunk and left common carotid artery commonly called the “bovine arch.” The bovine arch (in cattle) bears no resemblance to this branching pattern described in humans.[2] The aortic arch in cattle gives rise to a large trunk, which gives off a bicarotid trunk and both subclavian arteries.
