Abstract
INTRODUCTION: Stent migrations are described after peripheral endovascular treatments. We report a case of an unusual iliac stent movement after a successful angioplasty. REPORT: An occlusive distal intimal flap after aorto-iliac endoarterectomy was successfully fixed by stenting of the left external iliac artery. One month later, the patient was readmitted due to contralateral limb acute ischemia. Angiography revealed a right iliac artery thrombosis due to upstream stent migration from the left external iliac artery into the right common iliac artery. The patient underwent a combined surgical and endovascular rescue technique. CONCLUSION: Turbulent and pulsatile flow, associated with wall remodelling may explain this unexpected complication.
