Filter by:SUMMARY: The investigators are planning a clinical study to compare two methods of performing a procedure called TAVI, used in patients with severe aortic stenosis. In this procedure, the aortic valve is replaced in a less invasive way. Traditionally, access through the groin (femoral) is used, but now radial access (through the wrist) is being considered as an alternative. Reasons for the Study: - Currently, there is not enough solid evidence to support the choice between these two accesses. - The investigators want to understand if radial access could be safer and have fewer complications compared to femoral access. What the Investigators Will Measure: - Major complications, such as bleeding or vascular injuries. - Other important outcomes, such as functional recovery and quality of life. How the Investigators Will Do It: - The investigators will randomize patients to receive radial or femoral access. - The investigators will record which type of access is used and assess complications and outcomes. - The investigators will compare the results to understand if there are significant differences between the two groups. Ultimate Goal: - The investigators aim to improve the safety and efficacy of this procedure for patients. - The results of this study will help doctors make informed decisions on how to perform TAVI. Conclusion: - This study is crucial for enhancing care for patients with aortic stenosis and ensuring the procedure is performed in the safest and most effective manner. The results will benefit patients and guide doctors in choosing the best approach for each individual.
Groin wound infection after arterial femoral prosthetic reconstruction or percutaneous access and drug abusers are frequent and increase largely the post operative morbi-mortality. There is no perfect substitute to replace infected graft or to restaure femoral artery in septic condition moreover when all the femoral bifurcation is involved with a femoro-femoral bypass mandatory. Seeing the encouraging results of rolled pericardium patch to treat native and prosthetics aortic infections in term of patency and infection resistance, the investigators propose to evaluate the outcomes of this subsitute rolled with samples in case of femoro-femoral repair in septic condition.
The aim of this study is to evaluate the safety and efficacy of balloon expandable covered stenting of access complications, stenoses or pseudoaneurysms of the common femoral access.
The aim of the study is to investigate the effect of dapagliflozin or placebo on acetylcholine (Ach)- or nitroglycerin (GTN)-induced vasodilation of the forearm resistance vasculature, as determined by FBF measurement before and 10 minutes after 20 minutes of forearm ischemia.
The purpose of this study is to compare using Toughy needle has an advantage of reducing intravascular injection rates during cervical medial branch block.
Transcatheter aortic valve implantation (TAVI) is a rapidly growing treatment option for patients with aortic valve stenosis. Stroke is a feared complication of TAVI, with an incidence of around 4-5% in the first 30 days. Up to 50% of patients undergoing TAVI have an indication for oral anticoagulants (OAC) mostly for atrial fibrillation. OAC use during TAVI could increase bleeding complications, but interruption during TAVI may increase the risk for thromboembolic events (i.e. stroke, systemic embolism, myocardial infarction). Recent observational data suggest that periprocedural continuation of OAC is safe and might decrease the risk of stroke. Beside the potential reduction of thromboembolic events, continuation of OAC is associated with an evident clinical ancillary benefit for patients and staff. Since periprocedural OAC interruption not infrequently leads to misunderstanding and potentially dangerous situations, when patients are not properly informed before hospital admission or may experience difficulties with the interruption regimen. Hypothesis: Periprocedural continuation of oral anticoagulants is safe and might decrease thromboembolic complications without an increase in bleeding complications at 30 days
Brief Summary: The goal here is to evaluate dipyridamole in treating respiratory tract infection and circulatory dysfunction due to SARS-CoV-2 coronavirus in hospitalized CVID-19 patients. Infection with SARS-CoV-2 causes human COVID-19 (HCoV-19). The infection is associated with a deleterious inflammatory response and a prothrombotic state in addition to tissue damage from direct viral entry and proliferation. Dipyridamole has anti-platelet and anti-inflammatory effects. The drug was recently demonstrated to have anti-SARS-Cov-2 effect primarily in vitro. The concentration causing anti-viral effect in vitro is within that in the blood of humans taking this drug. As an oral tablet, it has the advantage of easy administration. Anti thrombotic, anti viral and anti inflammatory actions of this drug may be efficacious and safe in hospitalized subjects
Background: Pre-eclampsia, defined by the association of an arterial hypertension and significant proteinuria after 20 weeks of gestation, complicates 1 to 2% of pregnancies in France. Its pathophysiology involves angiogenesis impairment, upregulated maternal systemic inflammatory response, activation of oxidative stress and endothelial dysfunction. In a recent Danish nation-wide cohort study, pre-eclampsia was associated with a 69% increased risk of later developing scleroderma. Type of study: prospective observational case-control study. Primary objective of the study: to determine if a history of pre-eclampsia before systemic sclerosis diagnosis is an independent risk factor for vascular phenotype in sclerodermic women. Secondary objective: to describe all risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months before scleroderma diagnosis.
Allotransplants of vascularized composite tissues are subject to chronic vascular rejection, which can lead to graft loss. Currently, no imaging technique allows a reproducible quantitative exploration of the arterial trees of the hand, and therefore a satisfactory monitoring of transplants. Since 2014, flow MRI has been applied to the analysis of small-calibre arteries by the Image Processing Team at the Amiens-Picardie University Hospital. Between 2015 and 2017, several acquisitions were made in 3 patients who received facial allotransplantation, and the team recently developed a flow MRI protocol dedicated to the study of arterial trees in the hand. The main objective is to measure vascular flows of radial, ulnar and interdigital arterial trees in normal (healthy volunteers) and pathological situations (patients with radial forearm flap reconstruction and patients with hand allotransplantation) using the specifically developed flow MRI protocol.
Oxygen is required for an optimal muscle function. In patients with diabetes mellitus, hyperglycemia can cause vascular complications. The endothelium (inter layer of the blood vessels) can be damaged leading to a reduced oxygen flow towards the muscle cells. Besides, it is possible that mitochondrial dysfunction is occuring leading to reduced extraction of oxygen. Both conditions will lead to a reduced flow of oxygen towards the muscle and this can have impact on the production of energy necessary for optimal functioning. In this study, the investigators will examine the functionality of the blood vessels (1) and the uptake of oxygen into the muscles (2) in patients with diabetes mellitus type 1 and type 2 (with and without vascular complications) compared to healthy persons.
