Endovascular management of spontaneous rupture of the left subclavian artery.

Spontaneous rupture of the left subclavian artery is a rare condition that requires immediate surgical intervention. A 21-year-old man with a history of membranoproliferative glomerulonephritis, failed kidney transplant, and history of a type A aortic dissection that was surgically repaired was admitted with altered mental status and hypotension. He was found to have a left subclavian artery rupture. This was successfully managed with emergent thoracic endovascular aortic repair and carotid-subclavian bypass.
