In spite of preoperative "bridging" with a glycoprotein IIb/IIIa inhibitor, postoperative stent thrombosis can still occur in patients with prior DES undergoing surgery requiring antiplatelet medication interruption.

Among diabetic patients undergoing implantation of nitinol self-expanding stents in the superficial femoral artery, post-dilation with cryoplasty balloon reduced binary restenosis compared to conventional balloon angioplasty.
