Filter by:The objective of this prospective, multi-center, clinical investigation is to evaluate the MAGNITUDE BRS System for the planned treatment of narrowed infrapopliteal lesions. Up to 30 subjects will be enrolled at approximately 3 clinical sites in Australia.
The aim of this study is to compare total procedure time and success rate between FL-guided and US-assisted LSGBs in Lower Limb Ischemic patients.
The objective of this prospective, single-blinded, randomized controlled trial is to evaluate the safety and efficacy of the MAGNITUDE BRS System for the planned treatment of narrowed infrapopliteal lesions. Approximately 300 subjects will be randomized in a 1:1 ratio. The clinical investigation will be conducted at approximately 50 clinical sites internationally.
Clot extraction failure during mechanical thrombectomy is a major concern in the management of acute ischemic stroke related to large vessel occlusions. Indeed, it can occur in up to 10 to 30% of cases and, therefore, is associated with a very poor prognosis. These refractory occlusions frequently occur when an underlying intracranial atherosclerotic disease is present. Thus, one of the most promising rescue technique consists of placing a permanent intracranial stent, under dual antiplatelet therapy over the target refractory occlusion. This strategy is well studied in coronary occlusions where the atheroscotic mechanism is highly prevalent. However, as the ischemiated brain is at much higher risk of hemorrhagic complications, such strategy entails a greater risk. This raises the question of whether such risk is worth the reward of obtaining reperfusion. The investigators designed this randomized study in order to evaluate whether a strategy combining rescue pemanent intracranial stenting with the best medical treatment is superior to the best medical treatment alone in acute refractory large vessel occlusions.
The goal of this clinical trial is investigate the efficacy of a neuro/vascular-protective treatment with the drug Cerebrolysin in patients with acute ischemic stroke. starting immediately after completion of a EVT therapy. The main question the study aims to answer is: If a 10 days treatment with the neuro/vascularprotective drug Cerebrolysin (30 ml/day as intravenous infusion) is able to increase the overall outcome of EVT therapy? Participants will receive intravenous treatment with Cerebrolysin (30 ml/day) starting immediately after thrombolytic therapy and being continued for 10 consecutive days as one single daily infusion. The modified Rankin Scale (mRS) 90 days after onset of symptoms will be investigated, but also the improvement in other ratings as well as the time course of the improvement. In addition to the clinical outcome measures the study will assess neuroimaging perfusion CT-Perfusion parameters to evaluate possible direct improvement in microcirculation that might be an additional mechanism of action of cerebrolysin. CT-Perfusion being done immediately after EVT will provide ability to stratify the data according to non-favorable CT-Perfusion parameters after EVT versus favoravle.
The overall goal of this project is to determine if machine learning and analysis of neurospecific biomarkers can enable early detection of upcoming or ongoing cerebral ischaemia in patients suffering from subarachnoid haemorrhage with altered consciousness due to cerebral injury or sedation. Analyses of heart rate variability, electroencephalgraphy,nearinfrared spectroscopy, cerebral autoregulation, and brain injury specific biomarkers in blood and cerebrospinal fluid will be performed.
For the present study, 40 patients affected by critical limb ischemia of different severity will be enrolled: patients affected by critical limb ischemia undergoing subgenual femoropopliteal bypass; patients suffering from terminal ischemia causing gangrene and therefore undergoing major amputation of the lower limb. Biopsies from the first 20 enrolled patients will be used for miRNA profiling. The total of 40 biopsies obtained from all enrolled patients will instead be used for the validation of the miRNAs identified in the profiling. The results obtained will be compared with those obtained in 40 control patients affected by infrarenal abdominal aortic aneurysm (AAA) undergoing endovascular exclusion surgery (EVAR) of the AAA without any ischemia of the lower limbs. Also in this case the biopsies of the first 20 control patients enrolled will be used for miRNA profiling. The total of 40 biopsies obtained from all control patients will instead be used for the validation of the miRNAs identified in the profiling. A total of 80 patients (40 cases and 40 controls) will be enrolled.
This is a multicenter, randomized, double-blind, sham-controlled, investigator-initiated clinical study, to evaluate the clinical efficacy and safety of LF-rTMS in rescuing the ischemic penumbra, reducing disability rate and improving functional outcome in patients with acute ischemic stroke receiving early endovascular recanalization (bridging or direct endovascular therapy)
This is a multicenter, open-label, evaluator-blinded, investigator-initiated, randomized clinical trial, to evaluate the clinical efficacy and safety of LF-rTMS in reducing infarct size, reducing disability rate and improving functional outcome in patients with acute ischemic stroke within 48 hours after stroke onset.
The investigators evaluated whether the characteristics of ischemic stroke patients, door-to-needle time, and stroke risk factors were predictive variables for unfavourable outcomes.
