a Post-thoracic endovascular aortic repair (TEVAR) computed tomography angiography demonstrating an endoleak around the TEVAR, likely type II from multiple thoracic perforators and left subclavian artery (LSA). b Angiogram from left brachial catheter demonstrating type II endoleak from the LSA filling the aneurysm sac and multiple collaterals. c Coil embolization of the LSA with subsequent absent filling of the aneurysm sac. d Angiogram at the level of the TEVAR after coil embolization of the false lumen with no evidence of endoleak
