Case Report: Two Cases of Subclavian Artery Steal Syndrome due to Aneurysm Diagnosed by Ultrasound

This article describes two women with subclavian artery steal syndrome due to an aneurysm. Case 1 was a 48-yearyear-old woman who was found to have a 25 × 18 mm aneurysmal dilatation of the proximal segment of the right subclavian artery during a physical examination, followed by a finding of partial reversal of blood flow in the right vertebral artery, and Case 2 was a young woman who was found to have an aneurysmal dilatation of the descending aorta on a cardiac ultrasound, and then a passing look at the vertebral artery revealed systolic tangential traces in the right vertebral artery, and finally an aneurysm was confirmed in both cases by CTA. This case report discusses the causes, staging, and imaging presentation and diagnosis of subclavian aneurysms.
