Abstract

The presence of pre-existing intracoronary thrombus has consistently been shown to be among the strongest predictors of unsuccessful angioplasty and abrupt vessel closure. Abciximab, platelet glycoprotein IIb/IIIa receptor antagonist, through prevention platelet aggregation and coronary thrombosis, has shown promise in helping to decrease the incidence of complications of PTCA when prophylatically administered in patients presenting with unstable angina or complex lesion morphology for PTCA and in lower risk patients as well. However, the cost of abciximab and its associated increased risk of bleeding may limit its use as a prophylactic treatment. This study was performed to evaluate the effect of the rescue administration of abciximab in seven patients with thrombus containing lesion during angioplasty. Thrombus was disappeared in 4 patients and decreased in 2 patients, and the follow-up angiogram showed normal brisk flow in all 6 patients. There were no death or myocardial infarction on clinical follow-up at a mean of 7 months except one which was developed restenosis at the angioplasty lesion. Dissolution of thrombus and restoration or maintenance of TIMI grade 3 flow were achieved without complications after administration of abciximab when delivered in a rescue manner on thrombus containing lesion during angioplasty. These results showed that failure to give preprocedural proph-ylactic abciximab did not appear to exclude the possibility of a beneficial effect of abciximab, given therapeutically during the early stage of thrombus formation in patients with complicated lesion during angioplasty.
