Filter by:This study aims to evaluate the 12 month outcome of the mono- or combination therapy with iVascular Luminor DCB and Angiolite DES for treatment of TASC C and TASC D long tibial occlusive disease, presenting with critical limb ischemia.
The hypothesis of this study is that "the poor metabolizer or intermediate metabolizer of the cytochrome P450 2C19 genotype in patients with acute ischemic stroke is associated with increased risk of composite cardiovascular events (recurrent stroke, myocardial infarction, cardiovascular death) compared to those who of extensive metabolizer of the cytochrome P450 2C19 genotype".
This study aims to investigate the relationship between the concentrations of blood orphanin, norepinephrine and the morbidity of painless myocardial ischemia in patients with diabetes mellitus. Hopefully, the biomarker(s) in the blood of diabetic patients can be found for screening high risk patients in the diabetes sufferers to prevent the painless myocardial ischemia.
The objective of this clinical investigation is to evaluate the 6-month outcome of the Selution Sirolimus-coated Balloon for the treatment of long tibial occlusive disease (TASC C and D) in patients with Critical Limb Ischemia (CLI)
to detect the effects of RIC on stroke-induced immunodeficiency and inflammation response in acute ischemic stroke patients
Obliterative arterial disease of the lower limbs (AOMI) is associated with a high risk of cardiovascular events, with a linear relationship between a fall in the systolic pressure index and a risk of cardiovascular morbidity and mortality. Critical ischemia is the most severe stage of AOMI, associated with decubitus pain and / or foot ulceration. The severity of this arterial involvement involves functional prognosis of the lower limb with a high risk of amputation, as well as the patient's vital prognosis. In these patients, the rate of amputation and mortality at 1 year can reach 20%. Consequently, the goal of management in a multidisciplinary setting is threefold: the treatment of pain, improvement of the functional prognosis and improvement of the patient's vital prognosis. Revascularization should be attempted as often as possible for the purpose of limb salvage and improvement of patient survival. In the vascular medicine department, the indication and modalities of the revascularization procedure are discussed at a multidisciplinary consultation meeting. The medical-radiological-surgical expertise takes into consideration the patient's terrain and comorbidities and the technical possibilities according to the arterial damage. With the modernization and development of endovascular equipment dedicated to the hamstrings, the interventional radiology techniques in the management of critical ischemia allow the treatment of one or more arterial axes as well as a very distal revascularization in the arteries. foot with a lower morbidity-mortality compared to surgery, especially in the most fragile patients. Since 2013, the endovascular revascularization procedures performed by the interventional radiology team have been an integral part of the management of patients with critical ischemia hospitalized in the vascular medicine department. In patients with critical ischemia at high risk of major amputation and without the option of traditional endovascular or surgical revascularization, an endovascular revascularization technique for leg rescue is discussed as a last resort in multidisciplinary staff. This technique, performed by the interventional radiology team (MDP and GA), consists of an extra-anatomic endovascular femoro-popliteal bypass. We wish to describe the limb salvage rate and the preservation of autonomy in the 15 patients treated with this revascularization technique since 2013 in the vascular medicine department of the GHPSJ.
Sympathetic overactivity partly promotes the development of peripheral artery disease which mainly leads to ischemia of the lower limbs. Endovascular arterial denervation (ED) is a minimally invasive technique which could deliver Radiofrequency energy by a multi-electrode catheter to the Lower limb artery to restore Sympathetic activity. The purpose of this study is to evaluate the effects of multi-electrode radiofrequency ablation system on lower limb ischemia with PAD.
This study will focus on determining; - How accurate the test is in detecting poor circulation - How it's accuracy compares to other commonly used tests, and - Whether test results are linked to the chance of ulcer healing or amputation. Across 2 hospitals, 305 diabetic patients will be scanned using the focused ultrasound test as well as other commonly used tests to detect poor circulation. Their results will be compared to a full version of the ultrasound test to identify the most accurate.
Background During anaesthesia for repair of a broken hip, many patients experience low blood pressure. There have been many studies showing that patients who experience low blood pressure during anaesthesia are at increased risk of sustaining kidney or heart damage, strokes, having a post-operative infection, or dying. During anaesthesia, in most cases blood pressure is monitored using a cuff which inflates on the arm (the 'normal' way blood pressure is measured in a GP practice or hospital ward). This gives a reading each time the cuff goes up and down, every 3-5 minutes typically. There is a less well used way to measure blood pressure, using an additional cuff on the finger which gives a constant, continuous measure of blood pressure. We think that using this monitor, rather than the 'standard' monitor, will mean that low blood pressure is recognised more quickly, therefore treated more quickly, and will lead to patients having less exposure to dangerously low blood pressures. If this is the case, we hope that it will reduce how often patients experience kidney or heart damage, have an infection after surgery, suffer a stroke, and reduce the risk of death. Methodology To test this, we would need to run a large clinical trial comparing the continuous monitor to the standard monitor. This would be expensive and involve a great deal of work in a large number of hospitals, and so first we wish to determine whether the trial we would like to run is practical, and possible to deliver in the real world. To do this we plan to run the trial first on a small-scale feasibility (pilot) study, where we will recruit 30 patients, half of whom will have the standard monitor, and half of whom will have the continuous monitor. We will see what proportion of the patients who could enter the trial actually do so and complete it, and use it as an opportunity to iron out problems with the trial. If we find it is possible to run the trial on a small scale, we will apply for funding to run a full study. This will aim to answer the question of whether the continuous monitor improves the patient outcomes which were agreed during development with the patient public involvement group locally; rate of kidney damage, heart damage, stroke, post-operative infections, risk of death, and hospital length-of-stay. Expected outcomes and implications. We anticipate we will find the trial to be feasible with amendments to the way it is run, and if this is the case, we will apply to run the full scale trial. If this shows that using the continuous monitor improves the patient outcomes above, then it would represent new, significant evidence that may lead to the NHS adopting it's use as 'standard care' during anaesthesia for repair of a broken hip, and would like lead to similar trials in other operations where patients may benefit in a similar way.
In the present prospective, multicentric, randomized, double-blind, parallel, saline-controlled phase II clinical study; the investigators plan to evaluate the efficacy of sovateltide (IRL-1620 or PMZ-1620) therapy along with standard supportive care in patients of acute ischemic stroke.
