BACKGROUND Higher reperfusion rates have been established with endovascular treatment for acute ischemic stroke patients. There are limited data on the comparative performance of mechanical thrombectomy devices. This study aimed to analyse the efficacy and safety of the stent retriever device (Solitaire stent) by comparing procedure time, angiographic outcome, complication rate and long term cl...

PURPOSE To quantitatively evaluate the impact of carotid stent cell design on vessel scaffolding by using patient-specific finite element analysis of carotid artery stenting (CAS). METHODS The study was organized in 2 parts: (1) validation of a patient-specific finite element analysis of CAS and (2) evaluation of vessel scaffolding. Micro-computed tomography (CT) images of an open-cell stent ...

OBJECTIVES This study aimed to evaluate the degradation rate and long-term vascular responses to the absorbable metal stent (AMS). BACKGROUND The AMS demonstrated feasibility and safety at 4 months in human coronary arteries. METHODS The PROGRESS-AMS (Clinical Performance and Angiographic Results of Coronary Stenting) was a prospective, multicenter clinical trial of 63 patients with coronar...

BACKGROUND AND PURPOSE Mechanical thrombectomy by using a single stent retriever system has demonstrated high efficacy for recanalization of large-artery occlusions in acute stroke. We aimed to evaluate the feasibility, safety, and efficacy of a novel double Solitaire stent retriever technique as an escalating treatment for occlusions that are refractory to first-line single stent retriever mec...

BACKGROUND AND PURPOSE This study assessed the in vivo delivery, retrievability, short-term patency, and cellular response to a new flexible endovascular stent system in a rabbit model. The stent is designed for delivery through a microcatheter and is fully retrievable with electrolytic detachment from a delivery wire. METHODS We successfully deployed nine stents (range of sizes, 2.5-4 mm dia...

INTRODUCTION AND OBJECTIVES The interventional cardiologist chooses a specific stent type based on the risk-benefit profile for each case. In general, drug-eluting stents should be considered in all clinical conditions, except if there are concerns or contraindications for prolonged dual antiplatelet therapy. The aim of this work was to describe the use of bare-metal vs. drug-eluting stents in ...

OBJECTIVES The purpose of this study was to evaluate the efficacy and long-term outcomes of a novel polymer/carrier-free drug-coated stent (DCS) in patients with de novo coronary lesions. BACKGROUND The BioFreedom (BFD) DCS incorporates a low-profile, stainless-steel platform, with a surface that has been modified to create a selectively microstructured abluminal surface that allows adhesion ...

Introduction Tracheobronchial stenoses or fistulas caused by benign or malignant diseases are life-threatening and present as respiratory distress symptoms.Airway stent insertion is an effective and widely used method to manage this condition. When the stenoses or the fistulas exist in the lower trachea,main carina, and main-stem bronchi, the insertion of one hinged stent or angled stent, or tw...

OBJECTIVE To evaluate the biological effect of microengineered stent grooves (MSG) on early strut healing in humans by performing optical coherence tomography (OCT) analysis 3 weeks following the implantation. BACKGROUND In the experimental setting, MSG accelerate endothelial cell migration and reduce neointimal proliferation compared with bare metal stent (BMS). METHODS A total of 37 patie...

BACKGROUND Sirolimus-eluting stents (SES) reduce restenosis and revascularization rates, compared with bare-metal stents (BMS), in elective percutaneous coronary intervention (PCI). This study investigated the safety and efficacy of SES for emergency PCI in acute coronary syndrome (ACS) patients. METHODS AND RESULTS The 154 consecutive patients (SES: n=77, BMS: n=77) admitted to hospital with...
