Successful treatment of saphenous venous graft thrombus by tirofiban infusion.

A 60-year old man with a history of coronary-artery bypass grafting presented with symptoms of acute coronary syndrome. Coronary angiography revealed a huge intraluminal thrombus in the saphenous vein graft to the second obtuse marginal branch of the left circumflex artery. A glycoprotein IIb/IIIa inhibitor (tirofiban) was administered intravenously. Two days later, thrombus dissolution and Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow were evident on repeat coronary angiography. Glycoprotein IIb/IIIa inhibitors may be useful in a thrombus-laden saphenous-vein graft. Copyright 2010 Elsevier Inc. All rights reserved.
