Vascular Access Failure Due to Idiopathic Subclavian Artery Dissection

Abstract

We report a case of vascular access failure due to idiopathic subclavian artery dissection. A 61-year-old man visited our hospital due to absence of the thrill at the arteriovenous fistula. Ultrasonography revealed arterial dissection from the right subclavian artery to the brachial artery, and the true lumen was stenosed. A fenestration was performed to improve the access flow. Surgical treatment for idiopathic subclavian artery dissection is an option depending on the lesion.
