Coronary stent deployment without predilation: prevention of complications of venous graft angioplasty.
Saphenous vein graft stenting without predilation may potentially decrease procedural complications such as distal embolization and no-reflow phenomenon. In this report the authors describe the deployment of stents (three Wallstents, one Palmaz-Schatz, one Multilink, and one NIR) without predilation in five patients with unstable angina pectoris due to high-grade stenosis in old saphenous vein grafts. Stent deployment was successful in all patients without procedure-related complications. Stenting without predilation appears to be feasible in old bypass grafts with significant stenosis. The potential of this new stenting technique to reduce the risk of stenting complications should be tested by a randomized trial.
