Filter by:Patients undergoing vascular surgery are at a significantly high risk of perioperative cardiovascular, cerebral and renal events compared to those undergoing non-vascular surgery. This could be because of co-morbidities that are common in this patient group. Additionally, smoking, which is common in this population, may be a contributing factor. Oxygen therapy has been used for decades in order to reduce the risk of myocardial infarction and stroke in patients undergoing vascular surgery and pre-existing co-morbidities in the belief that increased inspired oxygen increases oxygen delivery to tissues, thereby reducing the risk for hypoxia and cell death. However, several studies published recently have questioned the routine use of high inspired oxygen concentration (hyperoxia) to improve oxygen delivery, specifically in the neonatal period but possibly even following myocardial infarction. This could be explained by the fact that increasing inspired concentrations of oxygen cause vasoconstriction in cerebral and coronary arteries, thereby reducing blood flow. Additionally, increased oxygen causes excessive production of reactive oxygen species (ROS), and repercussion injury from oxidative stress. The latter can lead to apoptosis (cell death) in myocardial or cerebral neurons. Despite the high risks of administering oxygen when not needed, it is routinely used in hospitals all over the world without a doctors prescription. This study aims to assess peri-operative complications up to 1 year following vascular surgery in patients randomised to receive high inspired oxygen concentration (endpoint: SpO2 98 - 100%) or minimal inspired O2 concentration (endpoint: SpO2 > 90%).
It is a study of basic research with mechanistically objectives and including clinical biological samples.
The object of the study is to determine whether different doses of PZ-128, when added to standard medical care in persons undergoing cardiac catheterization/percutaneous coronary intervention, will increase the risk of bleeding. A secondary objective is to determine whether patients treated with PZ-128 have fewer cardiac events such as heart attack, bypass surgery or stroke compared with those persons treated with the standard of care.
The objective of the ISR 14-04 study is to evaluate post-market safety and effectiveness of GORE® VIABAHN® Endoprosthesis for treatment of In-Stent Restenosis of the Superficial Femoral Artery.
The purpose was to evaluate 6-month outcomes of renal denervation(RDN) for the treatment of resistant hypertension in Chinese patients in a prospective cohort study.
The Registry of Acute Stroke Under Novel Oral Anticoagulants-Prime (RASUNOA-Prime), an investigator-initiated study, is a German multicenter, prospective, observational registry. It is performed at about 50 certified stroke-units and supported by an unrestricted grant from different pharmaceutical companies to the Heidelberg University Hospital. RASUNOA-Prime is designed to assess the emergency management of acute ischemic and hemorrhagic stroke patients with atrial fibrillation (AF) under different anticoagulation schemes pre stroke: Non-vitamin K antagonist oral anticoagulants (NOAC), Vitamin K antagonists (VKA), and no anticoagulation.
The purpose of this study is to compare the efficacy and safety of intravitreal Aflibercept monotherapy with the efficacy and safety of combined treatment with Aflibercept plus standard photodynamic therapy (PDT) with Verteporfin in age-related macular degeneration (AMD) patients with polypoidal choroidal vasculopathy (PCV).
A prospective, multi-center study to evaluate the safety and performance outcomes of the ArterX Vascular Sealant when used for prophylactic sealing of suture lines at the anastomosis between native vessel and synthetic vascular grafts.
The purpose of this study is to assess the safety and efficacy of paclitaxel administration using the occlusion perfusion catheter (OPC) for the prevention of restenosis in infrainguinal de novo, restenotic femoropopliteal and infrapopliteal stenoses and occlusions, and in-stent restenosis.
The purpose of the study is to obtain data regarding safety and efficacy of drug-eluting balloon luminor 14 & luminor 35 in the treatment of infrainguinal occlusive lesions (superficial femoral artery (SFA), popliteal artery (PA) and tibial arteries (ATs)) and restenosis from prior endovascular procedures in this sector.
