Human Immunodeficiency Virus (HIV) infection and use of protease inhibitors have been associated with accelerated atherosclerosis. Increased rates of coronary in-stent restenosis are reported in these patients. There is limited data available on peripheral vascular disease interventions on these patients. Herein we report an aggressive subclavian in-stent restenosis with an unexpected response ...

BACKGROUND AND OBJECTIVES MicroRNA 145 is known to be responsible for cellular proliferation, and its enhanced expression reportedly inhibits the retardation of vascular smooth muscle cell growth specifically. In this study, we developed a microRNA 145 nanoparticle immobilized, hyaluronic acid (HA)-coated stent. MATERIALS AND METHODS For the gene therapy, we used disulfide cross-linked low mo...

AIMS Sirolimus- and paclitaxel-eluting stents effectively reduce restenosis in small coronary vessels. The relative efficacy of these drug-eluting stents in this high-risk subset is not known. METHODS AND RESULTS A total of 360 patients undergoing percutaneous coronary intervention for de novo lesions in native coronary vessels with a diameter of <2.80 mm received randomly paclitaxel-eluting ...

The invention of the drug-eluting stent (DES) has brought about revolutionary changes in the field of interventional cardiology. In the DES era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. One of the emerging paradigms in the DES era is stent fracture. There are reports about stent fracture leading to in-stent restenosis or stent thrombosis. Most of th...

OBJECTIVES The aim of this study was to investigate the relationship between circulating monocytes and in-stent neointimal volume at six-month follow-up. BACKGROUND In-stent neointimal hyperplasia is the main contributing factor to in-stent restenosis. There is increasing evidence that white blood cells (WBCs), especially monocytes, play a central role in restenosis after stent implantation. ...

The objective of this study was to identify intravascular ultrasound (IVUS), angiographic and metabolic parameters related to restenosis in patients with dysglycemia. Seventy consecutive patients (77 lesions) selected according to inclusion and exclusion criteria were evaluated by the oral glucose tolerance test and the determination of insulinemia after a successful percutaneous coronary inter...

It is relatively difficult to treat restenosis when restenosis occurs following carotid artery stenting. Endarterectomy with simultaneous stent removal is an effective approach when restenosis occurs. The treatment method is still not well known. The present paper reports a case of restenosis after stenting that was treated with endarterectomy with a satisfactory treatment outcome. The patient,...

Drug-eluting stents (DES) have dramatically diminished but not eradicated in-stent restenosis (ISR) and even though they have resulted in single digit rates in simple lesions, it is not unusual to see double figure rates of ISR in more complex lesions and real world studies. Despite this problem little attention has been given to evaluate the pathogenesis of DES restenosis and the optimal treat...

All animal procedures were performed in accordance with UK Home Office Guidance on the operation of the Animals (Scientific Procedures) Act 1986 and institutional ethical approval (PPL60/4114 and PPL 60/4429). Male white Landrace pigs (SAC Commercial Ltd, Edinburgh, UK) and miR-21 knockout mice (1) were maintained on a 12 hour light/dark cycle with free access to food and water at a designated ...

Woman, 67 years old, with unstable angina and history of myocardial revascularization: left internal thoracic artery to anterior descending artery and graft with radial artery (RA) to right coronary artery branches. Coronariography showed stenosis of 90% in the RA graft, treated with conventional stent. After two months, the patient developed unstable angina related to in-stent restenosis, trea...
