BACKGROUND: The ideal oral anticoagulant agent during catheter ablation (CA) for atrial fibrillation (AF) remained unclear. HYPOTHESIS: Novel oral anticoagulants (NOACs) are safer and effective compared to uninterrupted vitamin K antagonists (U-VKA) among patients requiring CA for AF. METHODS: Four randomized controlled trials (RCTs) and 9 observational studies (OS) were selected using PubMed/Medline, EMBASE and the CENTRAL data bases (Inception-December-2017)...

Background The bedside fiber bronchoscope has been widely used in the diagnosis and treatment of respiratory disease. This study aims to assess the effect of using bedside fiber bronchoscope in sputum suction and alveolar lavage for treatment of stroke-associated pneumonia (SAP), compared with the use of conventional suction catheter. Methods One hundred and six patients with SAP were randomly divided into control group (n = 53) and experimental group (n = 53) for a controlled study. Patients in the two groups were conventionally treated with phlegm-resolving and anti-infective therapy...

Glial cell line-derived neurotrophic factor (GDNF) has demonstrated neurorestorative and neuroprotective effects in rodent and nonhuman primate models of Parkinson's disease. However, continuous intraputamenal infusion of GDNF (100 µg/day) resulted in multifocal cerebellar Purkinje cell loss in a 6-month toxicity study in rhesus monkeys. It was hypothesized that continuous leakage of GDNF into the cerebrospinal fluid compartment during the infusions led to down-regulation of GDNF receptors on Purkinje cells, and that subsequent acute withdrawal of GDNF then mediated the observed cerebellar lesions...

The number of patients in dialysis increases every year. In this review, we will evaluate the role of percutaneous transluminal angioplasty (PTA) according to patency of arteriovenous fistula and grafts. The main indication of PΤΑ is stenosis > 50% or obstruction of the vascular lumen of an arteriovenous fistula and graft. It is usually performed under local anesthesia. The infection rate is as low as the number of complications. Fistula can be used in dialysis in the same day without the need for a central venous catheter...

Narcolepsy-cataplexy is a chronic neurological disorder caused by loss of orexin (hypocretin)-producing neurons, associated with excessive daytime sleepiness, sleep attacks, cataplexy, sleep paralysis, hypnagogic hallucinations, and fragmentation of nighttime sleep. Currently, human narcolepsy is treated by providing symptomatic therapies, which can be associated with an array of side effects. Although peripherally administered orexin does not efficiently penetrate the blood-brain barrier, centrally delivered orexin can effectively alleviate narcoleptic symptoms in animal models...

The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

RATIONALE & OBJECTIVE: National vascular access guidelines recommend placement of arteriovenous fistulas (AVFs) over grafts (AVGs) in hemodialysis patients, but have not been comprehensively assessed in the elderly. We evaluated clinically relevant vascular access outcomes in elderly patients receiving an AVF or AVG after hemodialysis therapy initiation. STUDY DESIGN: Retrospective cohort study using national administrative data. SETTINGS & PARTCIPANTS: Claims data from the US Renal Data System of 9,458 US patients 67 years and older who initiated hemodialysis therapy from July 1, 2010, to June 30, 2011, with a catheter and received an AVF (n=7,433) or AVG (n=2,025) within the ensuing 6 months...

OBJECTIVE: Thermal vein ablation (VA) is the recommended treatment modality for superficial venous reflux, with a recommended positioning of the catheter at 2 to 3 cm from the junction of the deep venous system. In contrast, novel sealing technology for saphenous VA involves treatment starting at 3 to 5 cm distal to the deep junction. This study examines the effect of increasing catheter distance from the junction on the outcomes of VA using radiofrequency. METHODS: A retrospective single-center review of patients treated with VA was performed...

The surface ECG is a valuable mapping tool in patients with idiopathic and scar-related ventricular arrhythmias (VAs). A detailed analysis of 12-lead ECG can provide useful information in localizing the VA site of origin. This might help tailoring the ablation strategy to optimize procedural duration, increase the probability of success, and prevent complications. The aim of this article is to review the ECG features of both idiopathic and scar-related VAs and discuss their potential implications for optimizing the ablation strategy...

The use of catheters is ubiquitous in medicine and the incidence of infection remains unacceptably high despite numerous advances in functional surfaces and drug elution. Herein we report the use of a thermoplastic polyurethane containing an allyl ether side-chain functionality (allyl-TPU) that allows for rapid and convenient surface modification with antimicrobial reagents, post-processing. This post-processing functionalization affords the ability to target appropriate TPU properties and maintain the functional groups on the surface of the device where they do not affect bulk properties...

BACKGROUND AND OBJECTIVES: Quadratus lumborum block was first described in 2007 and currently there are descriptions of its achievement through four different injection points. This blockage provides abdominal wall and visceral analgesia, and one of its mechanisms is the dispersion of the local anesthetic into the paravertebral space. We describe the performance of a continuous quadratus lumborum type II block for postoperative analgesia in a partial nephrectomy. CASE REPORT: A 64-year-old woman, scheduled for partial left laparoscopic nephrectomy...

Acute pulmonary embolism (PE) is a major public health problem. It is the third most common cause of death in hospitalized patients. In the United States, there are up to 600,000 cases diagnosed per year with 100,000-180,000 acute PE-related deaths. Common risk factors include underlying genetic conditions, acquired conditions, and acquired hypercoagulable states. Acute PE increases the pulmonary vascular resistance and the load on the right ventricle (RV). Increased RV loading causes compensatory RV dilation, impaired contractility, tachycardia, and sympathetic activation...

Thromboses of the superior and inferior vena cava, either isolated or associated with distal deep venous thrombosis, are uncommon, but confer potentially serious morbidity and mortality. Incidence is increasing, especially with the prominence of intravascular devices. The range of treatment options is also expanding to include medical management, surgery, and endovascular techniques which are now frequently considered first line therapy due to lower reintervention rates and decreased periprocedural morbidity...

Venous thromboembolism, including deep vein thrombosis and pulmonary embolism, occur in up to 900,000 people per year in the United States. Current first-line therapy consists of systemic anticoagulation with a goal to prevent additional thrombus formation. Treatment with anticoagulation alone provides less than satisfactory results with some studies showing propagation of thrombus in almost 40% of cases. Current first-line therapy does not include active removal of thrombus and does little to alleviate acute symptoms and the damaging inflammatory response that may result in postthrombotic syndrome...

The incidence of venous thromboembolism, including both deep vein thrombosis and pulmonary embolism, is estimated at 300,000-600,000 per year. Although thrombosis may occur anywhere, it is thrombosis of the deep veins of the lower extremities that is of interest as this is where thrombosis occurs most often within the venous system. This article discusses the evaluation and interventions, including endovascular catheter-direct treatments, for patients with acute deep venous thrombosis.

Background and purpose Current large-bore catheters can be easily and safely placed in the intracranial vessels for the stabilization of microcatheters in several neurointervention scenarios. We considered that a novel 3.4 French catheter (TACTICS, Technorat Corporation, Aichi, Japan) might be useful for intermediate/distal access in a triaxial system. Here, we present our initial experience using the TACTICS catheter for treatment of intracranial aneurysms. Materials and methods A total of 35 endovascular coils were placed to embolize unruptured intracranial aneurysms of the anterior circulation using the TACTICS catheter between December 2016 and November 2017...
