Stent-assisted coiling (SAC) represents an established treatment option for broad-based intracranial aneurysms. Here we report our initial and follow-up experience with the Neuroform Atlas Stent, a hybrid open- closed-cell low-profile stent in of All aneurysms treated by SAC intention to apply Stent between July 2015 December 2019 were included. Angiographic clinical results analyzed including ...

BACKGROUND Coronary artery stents are used for the treatment of acute or threatening vessel occlusion complicating coronary angioplasty or for prevention of restenosis after angioplasty. The current randomized trial compared the procedural outcome and long-term patency of 2 different flexible stents in unselected lesion morphology. METHODS The study population consisted of consecutive patient...

We read the interesting article by Schneiders et al, entitled “A Flow-Diverting Stent Is Not a Pressure-Diverting Stent.” The authors measured intra-aneurysmal pressure before, during, and after placement of a flow-diverting (FD) stent and found that the pressure inside the aneurysm momentarily decreased during placement but was restored to baseline values within minutes. They agreed with the a...

Intravascular ultrasound (IVUS) is a useful diagnostic method that provides valuable information in addition to angiography regarding the coronary vessel lumen, dimensions, plaque burden, and characteristics. The major use of IVUS in coronary intervention is to guide interventional strategies and assess optimal stent deployment. Since the introduction of the drug-eluting stent (DES), concerns a...

INTRODUCTION Primary infection of a bare metal stent is a rare condition, associated with significant morbidity and mortality. Definitive treatment includes stent removal and arterial reconstruction. REPORT This study details a common iliac stent infection after re-intervention for iliac stent occlusion, complicated by pseudoaneurysm formation and septic embolisation. Potential risk factors f...

Very late thrombosis in an implanted bare-metal stent is a very uncommon event outside the context of brachytherapy and few data about its pathophysiology are available. We performed an intravascular ultrasound study during primary angioplasty in five patients with very late bare-metal stent thrombosis and carried out a histological analysis of the material removed by manual thrombectomy. The m...

PURPOSE To assess the safety and efficacy of one, two, or three trabecular microbypass stents in eyes with primary open-angle glaucoma (OAG) not controlled on ocular hypotensive medication. A total of 119 subjects were followed for 18 months postoperatively. MATERIALS AND METHODS Subjects with medicated intraocular pressure (IOP) 18-30 mmHg and postmedication-washout baseline IOP 22-38 mmHg w...

OBJECTIVES This study sought to study stent thrombosis with the paclitaxel-eluting Taxus stent. BACKGROUND The incidence and timing of stent thrombosis after drug-eluting stent placement compared with bare-metal stent implantation remain unsettled, with consequent uncertainty about risk stratification and long-term recommendations for antiplatelet medications. METHODS This study used a pati...

OBJECTIVES To analyze factors responsible for stent fracture in percutaneous pulmonary valve implantation (PPVI) by finite element method. BACKGROUND PPVI is an interventional catheter-based technique for treating significant pulmonary valve disease. Stent fracture is a recognized complication. METHODS Three different stent models were created: (1) platinum-10% iridium alloy stent - resembl...

BACKGROUND Drug-eluting stents have improved the efficacy of percutaneous coronary intervention and made it the preferred therapy in the treatment of ischemic heart diseases including acute coronary syndromes. The objective of the study was to compare the clinical efficacy and safety of sirolimus-eluting stent with that of zotarolimus-eluting stent following percutaneous coronary intervention f...
