Abstract

|
|
|
An aberrant right subclavian artery is the most common arch anomaly, and it occurs in approximately 1.0% of the population. It is caused by obliteration of the right fourth aortic arch during the early embryologic development. Aberrant right subclavian artery originates from a diverticulum; this was originally described by Kommerell. Aneurysms arising in an aberrant subclavian artery are rare, but they constitute a potentially lethal condition that can be treated successfully when this is appropriately identified. The presence of an aneurysm of the artery or Kommerell’s diverticulum at its aortic origin is more likely to produce symptoms from the esophageal compression. Virtually all these patients have a superior mediastinal mass that may be asymptomatic, but such patients usually have symptoms of dysphagia, chest pain, or shortness of breath. The presence of an aneurysm of an anomalous subclavian artery is an indication for surgical resection. Resection of the aneurysm may be approached through either a right or left thoracotomy. We present here a case of an aberrant origin of the right subclavian artery together with a review of the literature.
