Isolated Subclavian Artery Aneurysm: Evaluation by Transesophageal Echocardiography

Abstract

A 50-year-old man was evaluated following a motor vehicle accident. Chest X-ray showed a widened mediastinum. Transesophageal echocardiography was helpful in identifying the left subclavian artery and in demonstrating an isolated subclavian artery aneurysm. The TEE findings correlated well with the results of chest CT. Using TEE for the identification of the aortic branches in patients with chest trauma may be critical.

Successful Balloon-assisted Coil Embolization of Right Subclavian Artery Aneurysm: A Case Report

“…Approximately 50% of subclavian artery aneurysms are detected in the absence of symptoms/signs. 8) On the other hand, according to a report published by Vierhout et al involving 381 patients, local signs, such as pulsatile masses, accounted for 51% of signs, aneurysm enlargement-related mass effects (hoarseness, brachial plexopathy, airway stenosis, and vascular stenosis) for 36%, intra-aneurysmal thrombus-related distal thromboembolism for 22%, and aneurysmal rupture-related hemoptysis or hemothorax for 9%. 5) If rupture occurs, it may lead to a fatal outcome, as demonstrated for other aneurysms.…”
