In this paper, the authors quantify neointimal hyperplasia in iliac arteries after stent implantation, correlating clinical, arterial factors and stent material.Abstract:
OBJECTIVE: To quantify neointimal hyperplasia in iliac arteries after stent implantation, correlating clinical, arterial factors and stent material. MATERIALS AND METHODS: In the period from June/2003 to August/ 2005, 60 patients were submitted to percutaneous transluminal angioplasty and stenting. Among these patients, 30 were followed-up with intravascular ultrasonography. Data were analyzed in a laboratory of quantitative analysis by means of a specific software. RESULTS: Sixteen (53.3%) patients were men, and 14 (46.7%), women, and the mean age was 60.3 years. Arterial hypertension was observed in 22 patients (73.3%), smoking in 18 (62.1%), hyperlipidemia in 20 (66.7%), and diabetes in 9 (30%). A total of 20 nitinol stents (66.7%) and 10 stainless steel stents (33.3%) were implanted. Four patients were classified as TASC A (13.3%), 15 TASC B (50%) and 11 TASC C (36.7%). The neointimal hyperplasia volume ranged from 49.02 mm3 to 112.87 mm3 (mean, 80.33 mm3). The rate of intrastent obstruction ranged from 18% to 47% (mean, 27.4%). The clinical outcomes achieved with stenting were sustained through the follow-up. CONCLUSION: Neointimal hyperplasia is a common finding after percutaneous transluminal angioplasty and stenting, but in the present study the stenosis rate was never higher than 50%. There was no statistically significant difference in intrastent stenosis rates in relation to stents materials, clinical and arterial risk factors.read more

TL;DR: The goals of this new consensus are to provide an abbreviated document to focus on key aspects of diagnosis and management, and to update the information based on new publications and the newer guidelines, but not to add an extensive list of references.

TL;DR: This study compared the efficacy and safety of three antithrombotic-drug regimens — aspirin alone, aspirin and warfarin, and aspirin and ticlopidine — after coronary stenting to prevent stent thrombosis.

TL;DR: In this article, the safety and efficacy of sirolimus-coated BX Velocity stents were evaluated in 30 patients with angina pectoris electively treated with two different formulations of SIROlimuscoated stents (slow release and fast release).
