Filter by:Spanish registry of resorbable stent implantation in biliary benign strictures. This registry is sponsored by the Spanish Society of Vascular and Interventional Radiology (SERVEI) and conducted by the Research Group GITMI (Group of Research in Minimally Invasive Techniques) of the University of Zaragoza (Spain). A software tool hosted on the official website of SERVEI and the journal Intervencionismo will be used for data collection a(https://estudios.watsoncme.com).
The purpose of this study is to collect information about how patients feel when doctors manage their pain after lumbar spine surgery using a combination of EXPAREL® and bupivacaine injected into the lumbar spine at the end of surgery, compared to the patients that doctors use only EXPAREL® or bupivacaine to manage their pain. This information will help doctors determine which approach works best for patients who will receive surgery in their lumbar spine in the future.
Patients with peripheral artery disease will be treated with either drug coated balloon catheter, drug coated stent or uncoated stent.
Neural injury is a well-known complication following extreme lateral lumbar interbody fusion (XLIF). It has been found that up to 9.4% of patients will have either temporary or persistent neurologic deficit. This occurs with traversal of the psoas muscle or direct injury to lumbosacral plexus or sympathetic ganglion. While often temporary, it can cause hip flexor weakness, thigh numbness, or pain. Several studies have demonstrated reduced patient reported pain scores following steroid administration, particularly in the early postoperative period. However, few studies have investigated the efficacy of intraoperative local injection of corticosteroid in reducing the incidence and duration of postoperative pain or neurologic injury for XLIF patients.
Our hypothesis is that a plasma protein named osteopontin (OPN) could serve as a biological predictive marker of acute AVF dysfunction. In several scientific studies, plasma OPN was correlated with coronary stent restenosis, and with cardiovascular outcome in patients with diabetes and renal insufficiency. This protein is secreted by several cellular types, like distal tubule epithelial cells, macrophages, but also fibroblasts and cardiac and vascular endothelial cells, in response to several specific stimuli. It acts like a cytokine, inducing immunological mechanisms as well as tissue remodeling. The main objective of this study is to show that the amount of plasma OPN is higher in patients presenting with an AVF stenosis, compared with patients with a functioning AVF. OSMOSIS is a monocentric pilot study that will include patients into two groups during 12 months (no specific follow-up). The control group will include patients that have been dialyzed on an AVF, in the dialysis center of Nice University Hospital, for at least 3 months without any incident. The experimental group will include hemodialysis patients hospitalized in the department of vascular surgery for acute AVF dysfunction, needing endovascular or open surgical revision for venous stenosis. Blood will be withdrawn right before dialysis or surgical procedure. Plasma OPN will me measured by ELISA. Their clinical data would be collected from medical file at the same time. After the procedure, patients will be followed-up according to usual protocols. To show a significant difference of 100ng/mL plasma OPN between the two groups, with a power of 90% and alpha risk of 0.05, we plan to include 76 patients
Patients with claudication or critical limb ischemia will be treated either with uncoated balloons or paclitaxel coated balloons in order to enhance the vessel patency in stenosed or occluded below the knee arteries
DeVA is a single blinded, prospective, multicentre RCT designed to determine the safety and effectiveness of a drug eluting angioplasty balloon compared with a standard angioplasty balloon in patients with symptomatic native AV fistula stenosis.
This study aims to assess the device success and the safety of Medinol's Drug Eluting Stent - BioNIR - with a modified delivery system. The BioNIR Ridaforolimus Eluting Coronary Stent System is a single use device/drug combination product comprising: - A mounted Cobalt Chromium (CoCr) alloy based stent - A Rapid Exchange (RX) delivery system - A polymer matrix coating - Poly n-butyl methacrylate (PBMA) and CarboSil® - Ridaforolimus drug - CAS Registry Number: 572924-54-0 It is indicated for improving coronary luminal diameter in patients with symptomatic heart disease due to lesions in vessels with reference diameters of 2.5 mm to 4.25 mm, including complex lesions.
The objective of this study is to assess the safety and effectiveness of the COVERA™ Vascular Covered Stent for the treatment of stenotic lesions in the upper extremity venous outflow of the Arteriovenous (AV) access circuit.
