title: Acute lower limb ischaemia due to delayed upstream migration of an iliac stent.
abstract: We report a case of acute limb ischaemia due to unusual upstream stent migration into the aorta 2 years after successful kissing stenting. Angiography showed a misplacement of both common iliac stent into the aorta, upstream migration with a fracture on the left external iliac stent into the iliac common artery, occlusion of the left iliac and femoral artery, dilatation of aortic bifurcation and stent separation on the right side. The patient underwent a successful axillo-bifemoral bypass graft. Vessel wall remodelling due to overestimation of stent size, aortic turbulence and rebound effect may explain this complication.
