Very Late Bare Metal Stent Thrombosis: What Can Be The Role of Instent Re-stenosis and Hyperhomocysteinemia?
نویسندگان
چکیده
A 62-years old man was admitted to emergency department suffering from chest pain. Resting ECG revealed ST elevation on inferior leads and he was diagnosed with acute inferior myocardial infarction. His past medical history revealed that a bare metal stent had been implanted in his circumflex coronary artery upon stable angina pectoris 45 months ago. Immediately performed coronary angiography demonstrated the occlusion of the stent in the circumflex coronary artery. A new bare metal stent was implanted and TIMI 3 flow was established after initial balloon angioplasty. No other causes but vitamin B12 deficiency and hyperhomocysteinemia were found for this non-smoker patient among other laboratory tests.

Repeat late instent-stenosis after an interval of four years in the same lesion after bare-metal and drug-eluting stent: a case report
In 2001, a 71-year old male was admitted to our hospital with unstable angina. The angiography revealed 2-vessel disease with a 90% stenosis of the proximal LAD. A bare-metal stent was implanted. Four years later the angiography showed a 80% instent-stenosis in the bare-metal stent but no progress at the other coronary arteries. A DES was implanted. Again, four years later, the patient presente...
متن کاملIncredibly late thromboses in first generation drug eluting stents: a case series
BACKGROUND The drug-eluting stents have decreased the incidence of instent restenosis compared to bare metal stents. But, the incidence of late and very late stent thrombosis has increased with the drug-eluting stents. CASE PRESENTATION We are here, reporting three cases of incredibly late instent thrombosis, each one occurring after more than 50 months of drug-eluting stent placement. CONC...
متن کاملBare Metal Stent Thrombosis and In-Stent Neoatherosclerosis
Very late stent thrombosis occurs in patients with bare metal stent implantation, although the annual incidence is much lower than that after drug-eluting stent implantation. In-stent neoatherosclerosis with ruptured plaques and thin-cap fibroatheromas has been observed in bare metal stents. Atherosclerotic plaques harvested from patients with very late stent thrombosis and those with acute cor...
متن کاملNew stent design for use in small coronary arteries during percutaneous coronary intervention
Patients with diabetes mellitus, of female gender, increased age, and/or with peripheral vascular disease often develop coronary stenoses in small caliber vessels. This review describes treatment of these lesions with the paclitaxel-eluting 2.25 mm TAXUS(®) Liberté(®) Atom™ stent. Given the same stent composition, polymer, antirestenotic drug (paclitaxel), and release kinetics as the first-gene...
متن کاملChoice of Drug Eluting Stent: A Review
The development of stent has been a major achievement in treating obstructive coronary artery disease (OCAD). The main obstacle in the long term success of percutaneous coronary intervention (PCI) was the neo-intimal hyperplasia developed within the stent, which may leads to instent restenosis. The introduction of Drug-eluting stents (DES) shows steep decrease in angiographic restenosis when co...
