Filter by: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 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.
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.
The current study proposes to investigate the effects of chronic snus use on the blood vessels. Several cardiovascular endpoints are measured using various methods in healthy daily snus users as well as in healthy matched controls.
