Active clinical trials for "Vascular Diseases"

The aim of this study is to determine the frequency of cardiac and cerebral involvements in patients with idiopathic thrombotic microangiopathies on diagnosis. Patients will be assessed for cardiac involvement (troponin Ic level and cardiac ultrasonography) and cerebral involvement (cerebral MRI). The investigators will assess whether serum troponin Ic on diagnosis can predict morbidity and mortality of patients with a thrombotic microangiopathy at the acute phase. The primary outcome measurement is the event free survival at day 30, as defined by death, myocardial ischemia, arrhythmia, severe cerebral injury and disease exacerbation. An increase in troponin Ic on diagnosis is defined as at least one result above 0.2 ng/ml among the three daily analyses performed after TMA diagnosis.

Principal objective is to investigate if the treatment with fluvastatin can prevent the progression of vascular graft disease in de novo renal transplant patients.

Abstract: It is intuitive that post discharge surgical complications are associated with increased patient dissatisfaction, and directly associated with an increase in medical expenditures. It is also easy to make the connection that many post hospital discharge surgical complications including surgical site infections could be influenced or exacerbated by patient co-morbidities. The authors of a recent study reported that female gender, obesity, diabetes, smoking, hypertension, coronary artery disease, critical limb ischemia, chronic obstructive pulmonary disease, dyspnea, and neurologic disease were all of among significant predictors of surgical site infections after vascular reconstruction was performed. The main concern for optimal patient care especially in geographically isolated areas of West Virginia is to have early, expeditious, and prompt diagnosis of early surgical site infection with subsequent indicated interventions. This theme will lead to patient satisfaction, minimizing third party interventions and decrease the total cost associated with these complications. Nevertheless, it seems reasonable to believe that monitoring using telehealth technology and managing the general health care patients receive after a hospital vascular intervention will improve overall health and reduce post-operative complications. Aims/Objectives: 1. The primary objective of the current project is to compare early and late outcomes for patients who receive post discharge health care monitoring (which includes using Telehealth electronic monitoring; THEM) to patients who receive standard of care (SOC) and routine discharge instructions and no monitoring. Methods: Randomize patients who are scheduled to have revascularization interventions with groin incisions to receive either telehealth electronic health care monitoring or normal standard of follow-up care. Follow patients for 4 weeks, record any 30-day hospital readmissions or complications. In addition, have participants complete the follow-up survey questionnaires.

The medical device "Vascular Join" represents a new anastomotic technology that should reduce the inter-surgeons variability in anastomosis construction and increase the performances in terms of results. It allows a perfect mechanical anastomosis without suture, avoiding the disadvantages of operation length and difficulty of the act, thrombosis, clamping and embolism. The "Vascular Join" creates automatically the connection between the vein or prosthesis at both ends and bridging the artery while preventing the passage of the needle and suture through the vessel wall and clamping pressure. This makes it very easy to construct a vascular anastomosis using the endoscopic technique less traumatic for the patient, lessen the pain of the patient, thereby reducing health care costs by reducing the length of hospital stay. No part of the device is in contact with the patient's blood because the whole system remains in the thickness of the arterial wall and outside the vessel. Thus, the formation of intimal hyperplasia is greatly diminished and the risk of occlusion of the anastomosis is less than the currently available risk when a suture is used. This risk is shown by studies on animals in labs, with a mean follow up of 12 months. The Vascular Join creates a perfect congruence of anastomosed vessels because it allows a perfect match between each vascular tunic. The medical device Vascular Join has been designed in order to: Reduce the suture time; Reduce the risk of occlusion of vein after the surgical process; Avoid the contact risk between the external material steel (surgical needle) and blood; Standardize the quality of anastomoses independently of the skill of the surgeon.

To determine whether recurrent stenosis following carotid endarterectomy could be reduced by pre- and post-operative oral administration of platelet-inhibiting drugs.

The dynamic angio-MR sequences with injection of contrast (CE ARM) allow the study of the vascular anatomy. These sequences, widely used in clinical routine have shown their utility, in particular in the detection of the cerebrovascular diseases. The 4D flow MR sequences allow to quantify arterial parameters such as the speed of the circulating flow. By allowing an anatomical analysis and a functional analysis of quantitative parameters, 4D flow MR sequences could replace 1/ the currently used dynamic MRA sequences that are less precise in term of spatial and temporal resolution; 2/ the invasive exploration by DSA for the detection of vascular lesion and complete the exploration of the cervico-encephalic vascular pathologies by providing hemodynamical measures not yet accessible in clinical settings. In this context, the aim of the study is to evaluate the feasibility and the clinical usefulness of this 4D Flow technique to image brain vascular disorders including steno occlusive disorders. The evaluation will include several steps: 1/ optimization of acquisition parameters for the cranio-cervical arteries; 2/ comparison of two strategies for the post-processing 3/ feasibility for imaging of brain vascular disorders.

The diagnosis of a patient with pulmonary hypertension (PH) requires many investigations. At present cardiac catheterisation is the cornerstone investigation in these patients where it is used to establish disease severity and estimate prognosis. It is an invasive procedure which is expensive and not without risk to the patient. Despite the multitude of tests performed, identifying those patients with PH who have a poor diagnosis can be difficult. The aim of this study is to improve the assessment of patients with PH using novel magnetic resonance techniques.

The purpose of this trial is to find out the appropriate way to treat DM patients with critical limb ischemia. This trial includes two parts. Part I focuses on the treatment of femoral arterial lesion and part II focuses on the treatment of below-knee arterial lesion.

This is a double blind crossover study designed to compare two different gadolinium products given at the same dose to patients undergoing MRA assessment of lower legs for the evaluation of peripheral steno-occlusive disease.

This is a Belgian prospective multicentre registry on the performance of the Smart stent in the superficial femoral artery according to the new tasc II-classification.
