Abstract
Introduction
A right-sided aortic arch is a rare congenital cardiovascular anomaly that arises from persistence of the right fourth aortic arch and regression of the left fourth aortic arch. This variation commonly gives rise to an aberrant left subclavian artery (ALSA). In this report, we present an unusual variation of a right-sided aortic arch with an isolated common subclavian trunk (CST).
Methods
During a routine dissection of a female cadaver, a right-sided aortic arch variation with an aberrant left subclavian artery was observed. The thorax was further dissected to reveal the right-sided aortic arch and anomalous origin of the ALSA from a CST.
Results
The ascending aorta arose from the heart to form a right-sided aortic arch which branched into 1) a CST, 2) a left common carotid artery, and 3) a right common carotid artery. The CST branched into a right subclavian artery and an ALSA which traversed posteriorly to the esophagus to its normal anatomical position. The descending thoracic aorta passed along the right lateral aspect of the vertebral column, traversed posteriorly to the esophagus, and continued descending in its anatomical position through the aortic hiatus.
Conclusion
Rare aortic arch congenital anomalies such as a common subclavian trunk predispose the body to numerous clinical complications. A common subclavian trunk can cause cardiovascular complications and gastrointestinal complications due to compression of the esophagus. A deep understanding of the variations in the aortic arch and its branches is necessary for all physicians when managing patients with cardiovascular and upper gastrointestinal symptoms.
期刊介绍:
Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
