Idiopathic Left Subclavian Artery Dissection.

We present a case of a 65-year-old male admitted for a small bowel obstruction who was incidentally found to have a left subclavian artery dissection on computed tomography angiogram (CTA) of the aorta. Non-traumatic subclavian artery dissection (SAD) is rare and only a few cases have been published in the literature. In this report, we review previously reported clinical presentations, subsequent treatments, and discuss factors that impact the choice between surgical vs conservative management.
