Aberrant Left Subclavian Artery Associated With Kommerell Diverticulum Causing Severe Nausea and Vomiting: A Case Report and Review of Literature

A right-sided aortic arch with an aberrant left subclavian artery and a Kommerell diverticulum is a very rare finding, and it can cause tracheoesophageal compression. We describe a 45-year-old female patient with a right-sided aortic arch in tandem with an aberrant left subclavian artery and a Kommerell diverticulum. She had an 8-month history of mild dysphagia and nausea. Reconstruction of the aberrant left subclavian artery was not possible because of its deep position and exposure limitation; the artery was, therefore, simply ligated between 2 clamps. Ligation of an aberrant left subclavian artery is acceptable when it is difficult to access the artery or when the artery has a narrow orifice.
