Filter by:The Chocolate Touch study is a randomized, multi-center, prospective, adaptive study, designed to show sufficient safety and effectiveness of the Chocolate Touch™ for use in superficial femoral or popliteal arteries with the intention of obtaining regulatory approval to market this device in the United States
The aim of this study is to determine whether early administration of aspirin in acute ischemic stroke patients treated with systemic thrombolysis is safe and can improve outcomes due to decreasing the number of early rethromboses.
Patients suspected of chronic mesenteric ischemia shall be investigated with gastroscopy-assisted laser Doppler flowmeter and light spectroscopy (GALS).
This is a prospective, multi-center, randomized, dose escalation study to document the effects of adventitial delivery of temsirolimus (Torisel) after revascularization of lesions below the knee in symptomatic patients with critical limb ischemia (CLI).
The registry includes patients undergoing cardiovascular and thoracic surgery at the Saarland University Medical Center, Homburg/Saar, Germany. This study is a monocentric, retrospective study investigating the development of NOMI and outcome of patients.
Endovascular treatment of below the knee disease is a well-established therapy to improve outcomes in patients with critical limb ischemia. Several large cohort studies demonstrated the safety and the efficacy of percutaneous recanalization and angioplasty for distal vessel disease. A successful recanalization of foot artery was related to a higher ulcer healing and a reduction of major amputation. Moreover absence of revascularization in a patient with critical limb ischemia is an independent risk factor for mortality. Despite the introduction of new devices dedicated to below the knee vessel disease treatment, with the development of guides and conical balloons, long term patency outcomes are still poor. Restenosis was observed in more than two thirds of patients within 3 months after angioplasty of tibial arteries with a high target lesions revascularization. These re-interventions are characterized by a higher morbidity and mortality due to several comorbidities associated to these patients. These data confirm the need to obtain more lasting results in order to improve long-term outcomes of these patients. Recently, the use of drug-eluting balloons (DEB) has revealed an increase in patency after angioplasty of the femoral artery. On the contrary, results for BTK arteries angioplasty have shown controversial results. The purpose of this study is to evaluate the safety and the efficacy of the Ranger™ SL paclitaxel coated balloon a model of drug eluting balloon in patients with critical limb ischemia.
Fragility, geriatric concept recent identification is defined by simple physical indicators. The literature suggests that it is related to the risk of hospitalization, falls, institutionalization and death. Some studies have shown a link with heart disease, including heart failure. The link with the TIA (transient ischemic attack) has however never been studied. A fortiori, the impact of the fragility of the risk of recurrent stroke after TIA is unknown. Several questions need to be asked: Among older patients hospitalized for TIA, what proportion of those completing the criteria of frailty? In this same population, is there a correlation between fragility and scores ABCD2 score itself predictive of the risk of subsequent ischemic stroke? In other words, fragile subjects who have a TIA Have a higher risk of ischemic stroke (which could cause a strengthening of prevention measures)?
This is a prospective, multicenter, randomized trial to determine the mechanisms of vascular healing. The study will evaluate subjects with peripheral artery disease (PAD) who require an endovascular intervention of the femoro-popliteal (SFA) artery to restore blood flow to the leg.
Endovascular treatment of acute ischemic stroke has shown strong benefit in several prospective randomized trials in the anterior circulation and endovascular therapy for basilar artery occlusion has shown promising results in several single-arm studies. This has led to a broad adoption of these techniques which are now considered standard of care in many institutions despite the lack of adequate evidence to prove their benefit. Indeed, the rates of symptomatic intracerebral hemorrhage in these studies have consistently been around 5% which raises the question as to whether patients could actually be harmed as opposed to helped by these procedures. This is a prospective, multi-center, randomized, controlled, open, blinded-endpoint trial, with the aim to evaluate the hypothesis that mechanical embolectomy with the Solitaire device is superior to medical management alone in achieving better outcomes in subjects presenting with an acute ischemic stroke caused by occlusion of the basilar artery within 6-24 hours from symptom onset.
The main purpose of this trial is to determine whether Xingnaojing, intravenously administered within 24 hours of symptom onset, improves the 3-month outcome in participants with acute ischemic stroke.
