However, the negative predictive value of a normal chest radiograph of good quality is 97 but this likely reflects the low incidence of blunt thoracic aortic injury. (2001) Patterns of Right Aortic Arch and Mirror-Image Branching of the Brachiocephalic Vessels without Associated Anomalies. Only 12.5 of mediastinal hematomas are due to aortic injury. McElhinney, D.B., Hoydu, A.K., Gaynor, J.W., Spray, T.L., Goldmuntz, E. However, it was originally described as a diverticular outpouching at the origin of an aberrant right subclavian artery with a. It usually refers to the bulbous configuration of the origin of an aberrant left subclavian artery in the setting of a right-sided aortic arch. Journal of Cardiovascular Surgery (Torino), 44, 783-784.įelson, W. Kommerell diverticula occur in some anomalies of the aortic arch system. Kommerell diverticula occur in some anomalies of the aortic arch system. (2003) Right Sided Aortic Arch and Aberrant Left Subclavianartery. Citation, DOI, disclosures and article data. (2012) A Case Report of Abnormal Origin of Right Recurrent Laryngeal Nerve from Right Vagus in Thorax. The aortic arch is the part of the aorta between the ascending aorta and thoracic descending aorta. Arch sidedness was assessed according to.

Surgery, Gynecology Obstetrics, 127, 1101.Īniruddha, S. Additionally, the CT images of the 1,170 patients were evaluated for variations in the aortic arch branching pattern. (1968) The External Laryngeal Nerve as Related to Thyroidectomy. (2011) CT Evaluation of Vocal Cord Paralysis Due to Thoracic Diseases: A 10 Years Retrospective Study. (2004) A Rare Case of Ortners Syndrome (Cardiovocal Hoarseness). A, Reconstructed image from a computed tomography (CT) angiogram of the neck demonstrates a standard configuration of the aortic arch brachiocephalic artery (BCA), left common carotid artery (LCCA), and left subclavian artery (LSCA). (2013) Recurrent Vocal Cord Paralysis Associated with Right Aortic Arch. Omer, K., Hakan, B., Umit, A., Ozeyir, Y., Turan, I. Archives of Otolaryngology, 102, 259-261. (1976) Causes of Recurrent Laryngeal Nerve Paralysis. The authors have no conflicts of interest to declare.Titche, L.L. It is nominally defined as starting at the level of the transthoracic plane of Ludwig, a horizontal plane from the sternomanubrial angle to the T4 vertebral body. The authors declare that no patient data appears in this article. The aortic arch represents the continuation of the ascending aorta. c Axial CT image at a lower level shows the left descending thoracic aorta. b Axial CT image at a lower level shows the arch has now reached the right (arrow) and continues as the descending aorta on the left. The authors declare that no patient data appears in this article. a Axial CT image shows a right aortic arch (arrow), which extends behind the oesophagus to reach the side. Tracheobronchial anomalies and stenoses: detection with low-dose multidetector CT. The authors declare that no experiments were performed on humans or animals for this investigation. Anatomical variations of the aortic arch branching pattern using CT angiography: a proposal for a different morphological classification with clinical relevance. Right Aortic Arch With Left Descending Aorta (Cervical Aortic Arch). Three major branches originating from aortic arch include the brachiocephalic artery, the left common carotid artery, and the. It runs upward and bends posteriorly to the left, and then descends to connect to the descending aorta at the level of the T4 vertebra. Ethical disclosures Protection of human and animal subjects The aortic arch begins at the level of the second sternocostal joint. Assessment of tracheomalacia or other airway dysfunction still requires video bronchoscopy. angio-CT angiography provides better spatial and temporal resolution, rapid image acquisition requiring only sedation or brief anesthesia in uncooperative patients, and three-dimensional image reconstruction, and is thus the preferred imaging modality, especially with the lower radiation levels required with modern equipment. This combination of imaging techniques is essential for preoperative assessment. In this case, the clinical presentation dictated the sequence of imaging exams – FOB followed by angio-CT. Vascular rings account for 1% of congenital heart defects and are the most common malformation causing airway compression.
