Diagnostic imaging confirmed the anatomical variant and associated subclavian steal syndrome.

The case highlights the diagnostic challenges and management of this rare vascular anomaly.

Abstract

A right-sided aortic arch with an isolated left subclavian artery represents a rare anatomical variant, posing diagnostic challenges and clinical complexities. Here, we present a case of a 14-year-old male presenting with respiratory symptoms, unveiling a right-sided aortic arch with an isolated left subclavian artery. Through detailed clinical evaluation, radiographic imaging, and diagnostic modalities including chest radiography, computed tomography angiography, ultrasound, and time-of-flight magnetic resonance angiography, the anatomical features and associated complications were delineated. The discussion encompasses embryological underpinnings, clinical manifestations, and therapeutic considerations, shedding light on the rarity and clinical implications of this anomaly.
