Aortic arch aneurysm and patent left internal mammary artery: technique of transposition of supra-aortic vessels and embolization of the subclavian artery.
Endovascular treatment of aortic arch aneurysms poses unique problems because of vascularization of the carotid arteries. Transposition of supra-aortic vessels is becoming an established and accepted strategy for expanding the applicability of stent graft repair. left subclavian artery (LSA) is not usually transposed because its overstenting does not produce relevant complications. Nevertheless, some selected cases need high-pressure revascularization of the LSA, such as in the presence of a patent left internal mammary artery. We present a technique of revascularization of supra-aortic vessels and "balloon protected" embolization of the origin of the LSA.
