As noted in the publication by law et al ¿effectiveness of proximal intra-operative salvage palmaz stent placement for endoleak during endovascular aneurysm repair¿, hong kong medical journal (2016 oct 24); doi: 10.12809/hkmj154799; one palmaz stent was placed too low and lodged in one of the iliac limbs of a non-cordis aaa graft-stent.Nonetheless, it served its function well in correcting the proximal endoleak.The product was not returned for analysis.No lot number was provided therefore a device history record (dhr) review could not be generated.The reported ¿stent inaccurate placement¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.Vessel characteristics and procedural factors are unknown.The device was effective despite the incorrect positioning.According to the instructions for use ¿inspect crimped stent for uniformity, protruding struts, adherence to balloon, and centered placement in relation to the balloon marker bands.Do not reposition stent or hand-crimp.In case of a deviation, return product to cordis.Two radiopaque marker bands indicate the dilating section of the balloon.When the cordis large palmaz balloon-expandable stent and delivery system is introduced into the vascular system, it should be manipulated under high quality fluoroscopic observation.¿ neither the dhr nor the limited information available suggests a design or manufacturing related cause for the reported event; therefore, no corrective/preventive action will be taken.
