Thrombosis of bare metal and patent drug eluting stent in patient operated for colorectal carcinoma : the utility of new guidelines in patients with malignancy

Percutaneous coronary intervention with stent placement is widely used to achieve revascularization of the myocardium, especially in acute coronary syndrome. There is increasing number of reports published concerning stent thrombosis both in bare metal stents as in drug eluting stents. According to the newest ACC/AHA/SCAI 2007th guidelines, bare-metal stent or balloon angioplasty is recommended as an optimal solution if surgery is to be performed in 6–12 months time after stent placement. We present a case of a 56-year-old male with colon carcinoma who suffered from post-operational myocardial infarction due to bare metal stent thrombosis, while the drug eluting stent remained patent. Currently, in our opinion, high level evidence is lacking in the literature in support for recommendations published in current ACC, AHA and SCAI 2007th guidelines regarding the choice of stent, antiaggregation and anticoagulation therapy. This case, together with others previously published suggests a need for development of an applicable strategy for selection and treatment of patients with increased perioperative risk of in-stent thrombosis in order to ensure optimal medical treatment.
