Paired Comparison of Vascular Wall Reactions to Palmaz Stents, Strecker Tantalum Stents, and Wallstents in Canine Iliac and Femoral Arteries

Abstract

The lower-hoop-strength, higher-profile tantalum Strecker stent is affected by vascular wall recoil and evokes a greater degree of neointima formation than the lower-profile, higher-hoop-strength Palmaz stent and Wallstent. Medial atrophy is pronounced outside the latter two stents. The rigid Palmaz stent can penetrate through the vascular wall in flexing arteries.
