Right-Sided Aortic Arch with Diverticulum of Kommerell and Aberrant Left Subclavian Artery: A Comprehensive Review 1. Introduction Right aortic arch with Kommerel's diverticulum and an anomalous left subclavian artery (ALSA) is a rare congenital vascular anomaly that can present with clinical manifestations ranging from asymptomatic to severe airway or esophageal compression. While often discovered incidentally on CT angiography, diagnosis is crucial due to the risk of progressive symptoms and potential complications, such as aneurysmal degeneration or rupture. This post discusses the etiology, pathogenesis, pathophysiology, epidemiology, clinical presentation, radiological features, treatment options, and prognosis of this anomaly.
