Vascular pathology of balloon-expandable flexible coil stents in humans

Academic Article

Abstract

  • The morphologic changes in atherosclerotic coronary arteries and saphenous vein bypass grafts after placement of a balloon-expandable flexible coil stent (Cook) are described. In each case, the vessels were patent despite morphologic evidence of injury and dissection in the vessel wall. The stented region was reendothelialized and the tissue overlying the stent wires consisted primarily of smooth muscle cells. There was minimal inflammatory reaction to the stent wires. These findings suggest that the balloon-expandable flexible coil stent can effectively maintain vessel patency even in the setting or postangioplasly lumen disruption. In addition, the vessels tolerate the metal prosthesis with little evidence of tissue inflammatory reaction. © 1992.
