The aims of this study were to reveal the prevalence of complications associated with PBV over a long-term follow-up, and to investigate the factors related to those complications, especially pulmonary restenosis. Forty dogs who underwent PBV were retrospectively reviewed. Long-term follow-up was available in 22 dogs. Exacerbation of PI and TR after PBV was observed in some dogs; however, right...

OBJECTIVES We tested the hypothesis that patients with the DD genotype of the angiotensin I-converting enzyme (ACE) gene who are treated with ACE inhibitors are at a higher risk of restenosis after coronary stent placement than patients who do not receive ACE inhibitors. BACKGROUND Two recent studies with a limited series of patients carrying the DD genotype suggested an unfavorable impact of...

INTRODUCTION In spite of improving results, the treatment of in-stent restenosis (ISR) of bare-metal stents (BMS), and particularly drug-eluting stents (DES), is a challenging clinical problem. There are promising but limited follow-up data concerning drug-eluting balloons in the treatment of BMS and DES restenosis. The goal of this real-world registry was to assess the long-term safety and eff...

BACKGROUND Previous comparisons of percutaneous coronary interventions (PCIs) and coronary artery bypass graft (CABG) surgery have demonstrated similar survival but have also generally found better health status outcomes (symptoms, function, and quality of life) with CABG. The principal limitation of PCI has been the occurrence of restenosis. No previous studies comparing the health status outc...

Percutaneous transluminal coronary angioplasty (PTCA) was first introduced by Andreas Gruentzig in 1977 [l] as an alternative form of myocardial revascularization for patients with coronary artery disease. During the early years of its application, PTCA was limited to patients with single proximal coronary artery disease, well preserved left ventricular function, and stable angina refractory to...

BACKGROUND Restoration of carotid artery patency is one of the most frequently performed operations in vascular surgery. One of the most important problems that occur both short- and long-term after carotid endarterectomy is recurrent stenosis. Despite advances in imaging studies and better knowledge of the mechanisms of atherogenesis, the mechanism of restenosis remains unclear. Patients with ...

In patients with in-stent restenosis (ISR) inside bare metal stents, drug-eluting stents reduce the recurrence of restenosis compared with balloon angioplasty. However, few data are available about this therapeutic modality in the case of diffuse restenosis. The aim of this study was to evaluate the immediate and mid-term outcome of sirolimus- and paclitaxel-eluting stent implantation in diffus...

OBJECTIVES This study sought to evaluate the long-term angiographic and clinical outcomes after the treatment of drug-eluting stent in-stent restenosis (DES-ISR) based on the angiographic pattern of restenosis. BACKGROUND Long-term outcomes after percutaneous treatment of DES-ISR are unclear. METHODS This study performed a retrospective analysis of 481 consecutive de novo DES-ISR lesions (n...

Four patients underwent angioplasty and stenting of medically refractory symptomatic intracranial atherosclerosis with the new Wingspan stent system. In all 4 patients, CT angiography (CTA) showed an abnormality within the stented segment that was suggestive of nonocclusive in-stent thrombus. However, subsequent conventional angiography findings were typical for in-stent restenosis. The CTA ima...

Tracheal stenosis in association with the double aortic arch (DAA) is uncommon; however, it carries a high risk of morbidity, mortality, and restenosis. Although surgery is the mainstay of managing a case of the DAA with tracheal stenosis, management of tracheal restenosis requires a multidisciplinary approach. In this case report, we present our successful experience in managing a child of DAA...
