Successful Endovascular Repair in a Patient with Isolated Proximal Subclavian Artery Dissecting Aneurysm: Case Report and Literature Review.

Spontaneous isolated subclavian artery dissecting aneurysm is rare. This is to our knowledge the first case in the world's literature to report a patient with subclavian artery dissecting aneurysm. Although the endovascular approach of treating subclavian artery pathologies is not challenging, the choice of using a covered stent for this patient was a new attempt in treating subclavian artery dissections. This case report highlights the possibility and safety of using covered stent in treating patients with subclavian artery dissecting aneurysms after reassuring the patency of the cerebral circulation system.
