Two cases of aberrant subclavian arteries were detected incidentally during computed tomography scan of the thorax for other medical conditions. The patients did not have weight loss or dysphagia lusoria. The origin and course of theaberrant subclavian arteries are related to the anomaly of the aortic arch. The variations of aberrant right subclavian artery with left aortic arch and aberrant left subclavian artery with right aortic arch on computed tomography are discussed.Journal of Kathmandu Medical CollegeVol. 3, No. 4, Oct.-Dec., 2014Page: 162-164

An aberrant right subclavian artery is the commonest aortic arch anomaly. Majority of them were asymptomatic. An aberrant subclavian artery is a rare cause of dysphagia in adults. This condition is also known as dysphagia lusoria. We report a case of dysphagia in a 49-year-old woman from an aberrant right subclavian artery. Diagnosis of her condition was made with barium swallow and MDCT (multidetector computed tomography) scan. She was managed conservatively.

Abstract Background Congenital anomalies of the aortic arch are important as they may be associated with vascular ring anomalies. The most common vascular ring anomaly in dogs is a persistent right aortic arch. However, published data of the distribution of the different types of vascular ring anomalies and other aortic arch anomalies are lacking. The objective of this retrospective descriptive study was to evaluate both the prevalence and the different types of aortic arch anomalies that can be detected using thoracic computed tomography (CT) examination. Archived thoracic CT examinations acquired between 2008 and 2020 at a single institution were retrospectively evaluated by 2 evaluators for the prevalence and type of aortic arch anomaly. Breed, age, and presenting complaint were obtained from the medical record system. Results A total of 213 CT studies were evaluated; 21 dogs (21/213, 9.9%) showed a right aortic arch and a left ligamentum arteriosum with compression of the esophagus. The following incidental additional findings were detected: aberrant left subclavian artery (17/21, 76.2%), branching from the persistent ductus arteriosus (PDA) (1/21, 4.8%), left-sided brachiocephalic trunk (3/21, 14.3%), bicarotid trunk (17/21, 81.0%), double aortic arch (1/21, 4.8%). One hundred ninety two dogs (192/213, 90.1%) showed a left aortic arch without esophageal compression. The following additional abnormalities were obtained in those dogs with left aortic arch: aberrant right subclavian artery (3/192, 1.6%) without clinical signs of esophageal compression, aberrant vessel branching from the aorta into the left caudal lung lobe (2/192, 1.0%), focal dilatation of the left or right subclavian artery (2/192, 1.0%), bicarotid trunk (1/192, 0.5%). Conclusion Similar to previous studies an aberrant left subclavian artery is the most common additional finding in dogs with persistent right aortic arch. Newly, a left-sided brachiocephalic trunk was identified in 14.3% of the dogs with a persistent right aortic arch; no additional compression was caused by the left sided brachiocephalic trunk. Similarly, aberrant right subclavian artery can be an incidental CT finding without causing compression of the esophagus.

Objectives. The aim was to determine the prevalence of aortic arch variations in 881 patients who underwent neck CT angiography for various reasons. Material and Methods. 881 patients were included in the study who had undergone neck CT angiography between 2010 and 2013. Results. Of 881 patients, 770 (87.4%) patients with classic branching pattern of the aortic arch (AA) were observed. Variations in branching pattern were seen in 111 (12.6%) patients. The most common variation was the origination of the left common carotid artery (LCCA) from the brachiocephalic trunk (BCT). This pattern was observed in 64 (7.2%) cases. In 25 (2.8%) cases, the left vertebral artery (LVA) originated directly from the AA between the origin of the LCCA and left subclavian artery (SCA). 17 (1.9%) cases had aberrant right subclavian artery. Three (0.3%) cases showed right aortic arch. Two cases had right aortic arch with aberrant left subclavian artery. Conclusions. Variations in the branching pattern of the AA are not rare. Head and neck surgeons and interventional radiologists should be aware of aortic arch variations. CTA is a reliable imaging method for demonstrating anatomical features and variations of the AA.

Kommerell’S Diverticulum

Background: A 57-year-old woman was diagnosed with Kommerell’s diverticulum in the setting of a right aortic arch on computed tomography. Case report: Although asymptomatic, the maximum diameter of the aneurysm was 55 mm; thus, she underwent surgery to prevent rupture of the aneurysm. A bypass was constructed from the left common carotid artery to the left subclavian artery. A stent-graft was deployed from the distal right subclavian artery, and coil embolization of the diverticulum was performed via the left subclavian artery. She was discharged after 12 days of surgery. The postoperative four-month follow up showed a smaller aneurysm. Conclusion: Thoracic endovascular aortic repair is feasible and effective for Kommerell’s diverticulum.

Paratracheal Air Cyst

A tracheal diverticulum is a type of paratracheal air cyst and is usually an incidental finding after a computed tomography scan of the neck and thorax. With an incidence between 1% and 4% in adults, tracheal diverticula are rare entities that can be symptomatic in certain cases. We present a case of a COVID-19 positive patient who presented to our hospital and was diagnosed with multiple tracheal diverticula during his hospitalization.
