The aortic arch, arch of the aorta, or transverse aortic arch (English: / eɪ ˈ ɔːr t ɪ k / [1] [2]) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea .

2024年7月23日 · The aortic arch represents the direct continuation of the ascending aorta and represents a key area for a review of normal variant anatomy and a wide range of pathological processes that range from congenital anomalies to traumatic injury.

2008年7月8日 · The normal ascending aortic diameter is 2 to 3 cm depending on patient age, size, and sex. The risk for aortic rupture, dissection, or death for the ascending aorta relative to absolute size was recently evaluated by Davies et al. 18 They identified that the median aortic diameter at the time of rupture for the ascending or arch aorta was 6 cm ...

2024年4月21日 · There are three major branches arising from the aortic arch. Proximal to distal: Brachiocephalic trunk: The first and largest branch that ascends laterally to split into the right common carotid and right subclavian arteries. These arteries supply the right side of the head and neck, and the right upper limb.

2023年8月8日 · The aortic arch is the section of the aorta between the ascending and descending aorta. As it arises from the ascending aorta, the arch runs slightly backward and to the left of the trachea. The distal segment of the aortic arch then traverses downwards at the fourth thoracic vertebra. From this point on, it continues as the descending aorta.

2023年7月19日 · This activity deals with understanding the embryology of the aortic arch, the anatomy of a normal aortic arch and its anomalies, types of aortic arch anomalies that can give rise to a vascular ring, its symptomatology and how to diagnose and manage a patient with a vascular ring. It will also review the role of an interprofessional team.

In this article, we review the classification of aortic arch anomalies with a focus on embryologic development and clinical features. Understanding the normal development of the aortic arch is essential to understand and classify the various subtypes of aortic arch anomalies and variants.

The degree of ascending aortic dilation with age is relatively small and out of proportion to the aortic unfolding observed in the chest X-ray. Aortic dimensions can be measured by ultrasound, invasive angiography, X-ray computed tomography, and cardiac magnetic resonance.

2016年3月14日 · Dual right- and left-sided aortic arches give rise to bilateral common carotid arteries and subclavian arteries as independent structures. The selective involution of arch segments gives rise to the final adult aortic arch and serves as a mechanism to explain several common arch anomalies.

In the case of normal anatomy, the aortic arch (AA) gives rise to three main branches [1]. These are, from left to right, the brachiocephalic trunk (BCT), the left common carotid artery (LCCA) and the left subclavian artery (LSCA). The BCT further gives rise to the right common carotid (RCCA) and subclavian (RSCA) arteries.
