Abstract:
Objective:To explore the morphological features and ultrasonographic identification of common bare stents in pe-ripheral vessels.Methods:Totally 1 16 patients who received lower extremity arterial stenting(19 Complete stents,41 Everflex stents,19 Lifestent stents,5 Luminexx stents,47 S.M.A.R.T.stents,1 8 Zilver stents,139 stents in total)or carotid stenting (22 Acculink stents,8 Wallstent stents,30 stents in total),underwent postoperative ultrasonography,and the ultrasonographic features of intracorporal stents were compared among the different brands.Results:The ultrasonographic images of Complete stents were characterized by some distinct “Y array”.Everflex showed “fish scale”texture with curved metal grid.Lifestent showed fine-mesh and great compliance which could bend along with the flat superficial femoral artery.Luminexx showed typi-cal “Fishing net”structure with big mesh and dotted-line circularized metal shadow on the vertical section.S.M.A.R.T. showed staggered pattern,which was close and clear,and the metal mesh was straight,which was flat and smooth on the ver-tical section.Zilver showed staggered “V”pattern.Acculink was characterized by an axial metal “spine”throughout the whole stent.On the vertical section of ultrasonographic images of Wallstent,the bias metal shadow in the same direction appeared in-stead of staggered pattern.Conclusions:It is feasible to identify common stents in peripheral vessel by ultrasonography.It is crucial that ultrasonographic evaluation in clinical practice should be based on the features of different stents.
