Kommerell's diverticulum (KD) combined with a right-sided aortic arch (RAA) and an aberrant left subclavian artery (ALSA) is a rare congenital vascular anomaly causing significant compressive dysphagia. Treatment options, including open surgery, thoracic endovascular aortic repair and hybrid approaches, are debated due to anatomical complexities. We report a 48-year-old female with dysphagia from symptomatic KD, RAA and ALSA, clearly delineated by preoperative computed tomography angiography.

An aberrant right subclavian artery (ARSA) is a congenital vascular anomaly in which the right subclavian artery originates directly from the aortic arch distal to the left subclavian artery. Although often asymptomatic, ARSA can lead to clinical complications, such as dysphagia, upper respiratory issues, and vascular events. In this study, we examined the gross anatomical and histological characteristics of the ARSA based on three cadavers selected from a total of 7 ARSA cases identified among 3,158 specimens dissected between 1948 and 2024 at Nihon University School of Medicine (overall incidence: 0.

Kommerell's diverticulum (KD) is a rare vascular anomaly characterized by aneurysmal dilation of the descending aorta at the origin of an aberrant subclavian artery, which can occur in either a right- or left-sided aortic arch. Aberrant right subclavian arteries are found in approximately 0.5% to 2% of the population while aberrant left subclavian arteries are less common, occurring in only 0.

Background: Aberrant subclavian artery (ASA), though rare, can cause dysphagia lusoria and significantly affect quality of life. Conventional treatment involves open ligation and division of ASA, but a robotic approach is becoming more popular. This study assessed outcomes in patients undergoing robotic ASA division.

A 66-year-old male developed dysphagia due to external compression of the esophagus caused by an aberrant left subclavian artery, as part of a rare congenital anomaly of a right aortic arch. This represents an incomplete vascular ring-an anatomical variant of the right aortic arch - which is typically asymptomatic but may present with swallowing difficulties in adults, as demonstrated in this case.
