Local Hemodynamic Changes Immediately after Correction of an Aberrant Right Subclavian Artery in a Dog: A Contrast Computed Tomographic Study. | LitMetric
A 1-year-old female Akita dog was referred for intermittent regurgitation. Computed tomographic angiography (CTA) showed an aberrant right subclavian artery (ARSA), resulting in constriction of the esophagus. After surgical ligation of the ARSA, CTA showed that the ARSA was not enhanced by contrast medium, and that sufficient collateral circulation of the right forelimb was supplied through the vertebral artery. Furthermore, the right and left vertebral arteries merged into the basilar artery at the level of the atlas, and no abnormal expansion of the ventral spinal artery was observed. Overall, we demonstrated the importance of post-surgical CTA for identification of surgical complications, including the formation of abnormal vessel alterations.
Objective: To analytically depict the associated malformations of polysplenia syndrome (PS) in adults via computed tomography (CT).
Materials And Methods: The incidence of malformations associated with PS in twelve adult patients was retrospectively analyzed via CT imaging.
Results: The number of splenic nodules ranged from three to twelve; the splenic nodules were located in the left upper quadrant in nine patients and in the right upper quadrant in three patients.
Dysphagia lusoria is a rare condition characterized by swallowing difficulties due to vascular compression of the esophagus. While most commonly caused by an aberrant right subclavian artery (ARSA), other vascular anomalies can also lead to this condition. We present a unique case of dysphagia lusoria in a 20-year-old Ethiopian male, caused by a vertebral artery originating anomalously from the aortic arch.

Objectives: This study aimed to evaluate the association of aberrant right subclavian artery (ARSA) with genetic abnormalities and postnatal symptomatology, by comparing isolated and non-isolated ARSA cases.
Methods: Retrospective, descriptive and comparative study involving fetuses diagnosed with ARSA during routine fetal ultrasound scans, between 19 and 40 weeks, in a tertiary referral university hospital in Barcelona from January 2007 to December 2023.
Results: Out of 154 fetuses diagnosed with ARSA, 75.
Kommerell's diverticulum with an aberrant subclavian artery is a rare congenital aortic arch anomaly. Therefore surgical indication and strategy are not well established. A 43-year-old man was referred to our hospital with a chief complaint of chest and back pain.
A 61-year-old man was referred to our hospital for Stanford type A acute aortic dissection and an emergency operation was planned. In this case, the aberrant left vertebral artery originated directly from the aortic arch. Total arch replacement at the level between the left carotid artery and left aberrant vertebral artery was performed and an open stent graft was deployed in the true lumen of the descending aorta to obtain better distal aortic remodeling.
