A right-left aortic arch pattern made up by a bicarotid trunk, a left subclavian, a left vertebral and a right retroesophageal subclavian artery.
Summary of "A right-left aortic arch pattern made up by a bicarotid trunk, a left subclavian, a left vertebral and a right retroesophageal subclavian artery."
We present several vascular variations of the aortic arch vessels observed in a 35-year-old man during magnetic resonance angiography (MRA). The arterial branches of the aortic arch are from right to left: a bicarotid trunk, a left vertebral artery, a left subclavian artery, and a right retroesophageal subclavian artery. The right vertebral artery arises from the right carotid artery. Although a right retroesophageal subclavian artery has been reported in association with different anatomic variations of the aortic arch, to our knowledge this is the first MRA description of this particular combination of variations.

Medical and Biotech [MESH] Definitions
The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
Artery arising from the brachiocephalic trunk on the right side and from the arch of the aorta on the left side. It distributes to the neck, thoracic wall, spinal cord, brain, meninges, and upper limb.
Aortic Valve Insufficiency
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
Aortic Valve Prolapse
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
We describe a case of a 63-year-old woman who presented with spontaneous dissection of the innominate and left common carotid arteries arising from a common trunk, so-called "bovine aortic arch." The...
INTRODUCTION: The left common carotid artery (LCCA) is usually a second branch of the aortic arch that arises between the brachiocephalic trunk (BCT) and left subclavian artery; relatively frequently,...
ABSTRACT: Management of extensive, chronic, dissecting aortic aneurysms after prior repair of the ascending aorta presents a technical challenge for surgeons. A symptomatic 64-year-old patient was adm...
We report a new aortic arch occlusion technique with a balloon for distal aortic arch repair via left thoracotomy using an open proximal method. Distal aortic arch repair via left thoracotomy sometime...
Abstract Purpose: To present a detailed description of aortic arch morphology in patients with aneurysm and dissection undergoing thoracic endovascular aortic repair (TEVAR). Methods: Morphological as...
Abnormalities of the aorta have been identified in patients who have undergone repair of coarctation of the aorta by various surgical techniques. These abnormalities are thought to contri...
The ARCH is a controlled trial with a sequential design and with a prospective, randomized, open-label, blinded-endpoint (PROBE) methodology. The objective is to compare the efficacy and t...
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Magnevist (the study drug) used for MRI of the aortic arch and cerebr...
Even though the lower part of the body does receive some blood supply during Cardiopulmonary Bypass(CPB) surgery, it may not be enough. As a result of this lowered blood supply, there are...
One known risk of pediatric heart surgery is the possibility for brain damage. In may cases this problem results from a lack of oxygen rick blood flow to the brain during surgery. Recentl...
