[Epub ahead of print] Mechanism of Stent Failure in a Patient with Fibromuscular Dysplasia Following Renal Artery Stenting. Wang LC1, Scott DJ2, Clemens MS2, Hislop SJ3, Arthurs ZM3. Author information Abstract Endovascular techniques used in the management of renal artery stenosis (RAS) have unique complications, to include stent facture, thrombosis, aneurysm formation, migration, and in-stent restenosis. Described here is an unusual complication of renal artery obstruction and recurrent hypertension without progressive loss of renal function, secondary to intermittent arterial kinking with respiratory and cardiac motion in a patient with fibromuscular dysplasia (FMD). This mechanical complication has implication not only in successful endovascular treatment of RAS, but raises questions regarding the alterations in dynamic motion with the cardio-respiratory cycle in stented visceral arteries in other vascular pathologies requiring renal artery stenting (i.e. juxtarenal or pararenal aortic aneursyms).
