Acute ischemic stroke (AIS) is the leading cause of premature mortality and morbidity worldwide for both men and women. Extracranial carotid artery stenosis/occlusion is responsible for approximately 11.5%% of ischemic strokes, whereas extracranial large vessel disease comprises roughly 16.6% of ischemic strokes. Carotid artery disease has been the source of significant debate among neurovascular and cardiovascular specialists, as well as vascular surgeons, as to the best method of revascularization, surgical reconstruction versus endovascular recanalization...

PURPOSE: Children receiving treatment in the hospital frequently require intravenous (IV) access. Placement of short peripheral catheters can be painful and challenging especially in those children who have difficult access. Many children's hospitals have teams of specialized vascular access nurses experienced in peripheral catheter insertion, and at times use vein visualization devices, including ultrasound (US), to assist in peripheral IV placement. Our objectives were to describe the prevalence and success rate of US-guided peripheral IV placement by vascular access team nurses at a single tertiary children's hospital...

Stenosis or occlusion of central veins in hemodialysis patients is common, especially with previous intravascular catheter or device use. Superior vena cava (SVC) obstruction is emerging as a frequent chronic complication of central vein cannulation that not only jeopardizes the availability of vascular access for hemodialysis, but can become a life-threatening emergency. Clinical features of SVC syndrome can be subtle or dramatic, including facial swelling and shortness of breath, which require expeditious attention and intervention...

BACKGROUND: Percutaneous coronary intervention (PCI) procedures are increasingly performed on complex tortuous and heavily calcified coronary lesions. The GuideLiner® catheter (Vascular Solutions, Inc. Minneapolis, MN) is a rapid exchange guide catheter extension system. There is paucity of data about the efficacy of this device in complex PCI. Therefore, we aim to report the indications, success, and efficacy of GuideLiner use in treating complex lesion subset in the present study. METHODS: We collected data from all patients in whom the GuideLiner was used to facilitate PCI between April 1, 2011 and December 31, 2014 at a tertiary referral center in Toronto, Canada...

OBJECTIVE: Endovascular treatment is one of the most important treatments along with open craniotomy for cerebrovascular surgery. The successful treatment of endovascular disease relies on appropriate instruments and the surgeon's skill. Endovascular treatment needs to provide safe and stable access to the catheter cavity. Additionally, it is important to maintain a round shape without changing to an oval shape. The catheter for endovascular treatment has to be flexible and accommodate at least 0...

Magnetic particle imaging (MPI) is able to provide high temporal and good spatial resolution, high signal to noise ratio and sensitivity. Furthermore, it is a truly quantitative method as its signal strength is proportional to the concentration of its tracer, superparamagnetic iron oxide nanoparticles (SPIOs), over a wide range practically relevant concentrations. Thus, MPI is proposed as a promising future method for guidance of vascular interventions. To implement this, devices such as guide wires and catheters have to be discernible in MPI, which can be achieved by coating already commercially available devices with SPIOs...

New developments in infrarenal abdominal aortic aneurysm stent-graft devices have made more patients eligible for endovascular aneurysm repair (EVAR). Recent US Food and Drug Administration approval for fenestrated endograft repair and impending approval for iliac branch devices extend the proximal and distal landing zones. Better deployment systems allow for partial deployment of endografts to facilitate repositioning, and more flexible designs allow for treatment of angulated infrarenal aneurysm necks and tortuous iliac arteries...

Catheter-related bloodstream infections (CRBSI) are responsible for significant morbidity, mortality, and excess health care costs. It is increasingly evident that many CRBSI can be prevented with current knowledge and techniques. Preventive measures can be broadly grouped into clinical practice-based interventions and technologic innovations. Clinical practice-based interventions require changes in human behavior and can be subdivided into interventions before and at the time of insertion and postinsertion...

OBJECTIVE The long-term effectiveness of endovascular treatment of large and giant wide-neck aneurysms using traditional endovascular techniques has been disappointing, with high recanalization and re-treatment rates. Flow diversion with the Pipeline Embolization Device (PED) has been recently used as a stand-alone therapy for complex aneurysms, showing significant improvement in effectiveness while demonstrating a similar safety profile to stent-supported coil treatment. However, relatively little is known about its long-term safety and effectiveness...

Blood-contacting devices, such as intravascular catheters, suffer from challenges related to thrombus formation and infection. Nitric oxide (NO) is an endogenous antiplatelet and antimicrobial agent. Exogenous release of NO from various polymer matrices has been shown to reduce thrombosis and infection of/on implantable medical devices. However, the clinical applications of such materials have been hindered due to factors such as NO donor leaching and thermal instability. In this study, a novel approach is demonstrated in which one lumen of commercial dual lumen catheters is dedicated to the NO release chemistry, allowing the other lumen to be available for clinical vascular access...

The use of the tunneled central venous catheter (CVC) is steadily increasing worldwide as a means of vascular access for hemodialysis. The increased use of these devices, which often outlive the patients, and the extended time they are used are associated with more frequent complications. Among these, one of the emerging complications is that of the "embedded" or stuck catheter. This term refers to when the catheter cannot be removed after detaching the retention cuff. In medical literature, experiences with the removal of stuck catheters are described with the use of several different methods...

Owing to the overall increase in the use of DES, the number of patients presenting with DES restenosis is not insignificant in absolute terms. When DES restenosis occurs, it represents a challenging clinical entity in terms of classification and treatment. By providing near histology-level images, intravascular optical coherence tomography (OCT) has been used to describe vascular responses following PCI. Subsequently, OCT has been introduced to assess neointimal morphology and tissue characteristics of restenotic lesions to clarify the underlying pathophysiology...
