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

Variant Anatomy

Background: Variant branching patterns of the aortic arch are not infrequent but are commonly under reported. This study was conducted to determine the spectrum of Variant branching pattern of aortic arch and their prevalence using contrast enhanced computed tomography (CECT) images of the cases from a tertiary care centre.Methods:  Contrast enhanced computed tomography (CECT) images of aortic arch region from 1116(629 male and 487 female) cases from 18 to 85 years of age were examined retrospectively. The images were reviewed for normal and variant anatomy of aortic arch and the results were analyzed statistically.Results: Of 1116 patients, 878 (78.6%) cases showed normal and 238 (21.3%) cases had variant branching pattern of the aortic arch. The most common variation was the common origin of brachiocephalic trunk (BCT) and the left common carotid artery (LCCA) which was observed in 160 (14.3%) cases. In 8 (0.7%) cases, BCT and LCCA took origin from a single common trunk arising from the aortic arch. In 60(5.4%) cases, the left vertebral artery (LVA) originated directly from the aortic arch between the origin of the LCCA and left subclavian artery (SCA). 8 (0.7%) cases had aberrant right subclavian artery. Two (0.2%) cases showed right aortic arch.Conclusions: Interventional radiologists and surgeons should be well aware of variant anatomy of aortic arch. Contrast CT is a highly reliable imaging method for demonstrating anatomical features and variations of the arch.

Background: The azygos lobe is a rare variation of the right upper lobe of the lung, and prevalence of it in the general population varies widely between 0.1% and 8%. It can be diagnosed easily by thoracic computed tomography. Objective: In this study, by thoracic computed tomography, azygos lobe frequency and associated variations were evaluated. Materials and Methods: In this study, 5854 thoracic computed tomography with and without contrast applied for patients in the Kars Harakani State Hospital Chest Diseases Polyclinic between January 2014 and January 2018 were screened retrospectively. Results: A total of 5854 thoracic computed tomography showed that frequency of azygos lobe was 1.09%. Out of 64 patients with azygos lobe, 36 (56.25%) were male and 28 (43.75%) were female. Bovine artery was found in 8 (12.5%) cases, right-left carotid artery common origin in 3 (4.68%) and aberrant right subclavian artery in 1 (1.56%). Conclusion: The detected azygos lobe frequency is similar to literature and the most common accompanying variation is bovine artery. J Enam Med Col 2019; 9(3): 177-180

Arteria Subclavia

A rare case of a 79-year old women with dysphagia and dyspnea secondary to compression of the esophagus by an aberrant right subclavian artery (ARSA, A. lusoria) is presented. This abnormality is generally silent and often an incidental x-ray finding. Computed tomography and intraarterial angiography, including direct catheterization of the ARSA, established the diagnosis. The interdependence with a co-existing coronary artery disease is discussed. Thus, ARSA has to be taken into account in patients with abnormal x-ray findings presenting with dysphagia and dyspnea.

Abstract An aberrant right subclavian artery (ARSA) is a rare arterial anomaly. Although a few cases of total endovascular repair for the ARSA aneurysm have been previously reported, anatomical limitations and the possibility of endoleaks remained. In this case, we created 4 holes on the stent graft for each cervical branch, with reference to the preoperative computed tomography findings. This approach might enable us to repair all types of thoracic aortic aneurysms with ARSA with each anatomical feature.

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.

We report a simple endovascular repair for symptomatic aberrant right subclavian artery (ARSA) in an 11-year-old girl. She had undergone tracheostomy due to hypoxic encephalopathy after cardiac surgery and suffered from dyspnea. Computed tomography revealed tracheal stenosis caused by a vascular ring made with an ARSA and the right common carotid artery. Transcatheter ARSA embolization using an Amplatzer vascular plug and coils was performed. Symptoms improved within a few days after this intervention and no complications such as upper extremity ischemia were encountered. Computed tomography showed the ARSA around the trachea had reduced in size and tracheal stenosis was improved.
