Very late multivessel thrombosis of bare metal stents with concomitant patent drug-eluting stents after withdrawal of aspirin.

Very late stent thrombosis occurs in both drug eluting stent and bare metal stent. Withdrawal of antiplatelet therapy appears to be a potent correlate of late stent thrombosis that leads in majority of cases to acute myocardial infarction or death. A case is reported of very late bare metal stents thrombosis (33 months) in two different vessels after aspirin discontinuation because of a prostatectomy in patient treated simultaneously with bare metal stents and paclitaxel eluting stents, found patent. In conclusion, this case raise the question on the possible need to continue the antiplatelet therapy performing invasive or surgical procedures also in all patients treated with long-standing coronary bare metal stent.
