Carotid artery stenting via a femoral bypass graft: technical note.
BACKGROUND
We described a case of endoluminal stent placement for a cervical internal carotid artery stenosis in which access was obtained via the femoral bypass graft.


METHODS
A 70-year-old man with known disease of the carotid, peripheral, and coronary arteries as well as congestive heart failure presented for endoluminal revascularization of a severe right internal carotid artery stenosis. Transradial access was complicated by the left subclavian artery occlusion and hypercalcified aortic arch. Bilateral femoral artery was replaced with bypass graft because of atherosclerosis obliterans. An alternative approach was attempted via the exposed left femoral bypass graft. The left inguinal region was incised, and the left common femoral-popliteal bypass graft was exposed. After placement of a purse string suture at the puncture site, the guiding sheath was introduced into the graft and positioned into the right common carotid artery. Stenting was successfully performed, and the suture was tied after withdrawing the sheath.


CONCLUSIONS
This novel approach should be considered for endovascular procedures for which access to the carotid artery is limited.
