Active clinical trials for "Ischemia"

The objective of this prospective, multi-center, single arm study is to obtain further data on the safety and performance of the Drug-coated Balloon catheters in the treatment of the Superficial Femoral Artery (SFA) and Popliteal Arteries (PA).

Sovateltide (PMZ-1620; IRL-1620) is targeted to be used as a "Treatment for hypoxic-ischemic encephalopathy in neonates," which is a life-threatening condition. Sovateltide augments neuronal progenitor cell differentiation and better mitochondrial morphology and biogenesis to activate a regenerative response in the central nervous system. The only treatment for HIE is therapeutic hypothermia with limited success, and studies indicate that sovateltide may be beneficial in these patients.

This is a prospective, randomized, open-label, evaluator-blinded, single center, proof of concept trial to explore possible beneficial effect of minocycline on acute ischemic stroke (AIS) undergoing endovascular treatment due to basilar artery occlusion (BAO). Minocycline has excellent safety profiles, have been previously demonstrated individually to reduce infarction in animal models of stroke, and have potentially mechanisms of antioxidant, anti-inflammatory, anti-apoptotic and protection of blood-brain barrier. However, it is not known whether minocycline can reduce futile recanalization of endovascular treatment, and improve the outcome of patients with AIS due to BAO. Eligible and willing subjects will be randomly assigned to the treatment group or the control group. The treatment group will receive 200 mg oral minocycline within three hours prior to successful reperfusion, followed by 100 mg every 12 hours times for a total of 5 days. Both groups will receive endovascular thrombectomy and standard medical. The treatment with minocycline will start as soon as possible after diagnosis of stroke. Measures of stroke severity and disability will be recorded at baseline and through the follow-up periods (90 days). The evaluator will be blind to the allocation of patients further minimizing the bias.

To evaluate the efficacy and safety of head acupuncture combined with endovascular therapy for cerebral infarction compared with endovascular therapy alone

More than 80% of ischemic stroke (IS) patients have some walking disability, which restricts their independence in the activities of daily living. Physical therapy (PT) significantly contributes to gait recovery in patients after IS. However, it remains unclear, what type of gait training is more effective and which factors may have impact on gait recovery. Two hundred fifty IS patients will be enrolled to undergo a 2-week intensive inpatient rehabilitation including randomly assigned robot-assisted treadmill gait training (RTGT) or therapist-assisted treadmill gait training (TTGT). A detailed clinical and laboratory assessment of gait quality, as well as the degree of neurological impairment, quality of life, cognition and depression will be performed in all patients during the study. We hypothesize that these variables may also affect gait recovery in patients after IS. In a randomly selected 60 enrolled patients, a multi-modal magnetic resonance imaging (MRI), including functional MRI, will be performed to assess neural correlates and additional predictors of gait recovery.

The functional prognosis of patients with ischaemic stroke treated by thrombolysis and thrombectomy is associated with complete reperfusion of the occluded artery defined by an mTICI 2C or 3 score at the end of thrombectomy. However, this complete reperfusion is only obtained in 60% of patients. Most often, incomplete reperfusion is due to the persistence of distal occlusions, which are inaccessible to mechanical thrombectomy. Drug treatment, combined with thrombectomy to increase the rate of complete reperfusion, would be a major advance in the management of these patients. This is a non-randomized, monocentric, open-label, phase II trial to evaluate efficacy of dornase alfa intravenous administration in patients treated with intravenous thrombolysis and eligible for thrombectomy for ischemic stroke of the anterior circulation.

This is a Prospective randomized controlled study to evaluate the difference of safety，effectiveness between chocolate balloon and plain balloon dilatation in treatment of infrapopliteal artery lesions.

Ischemic stroke is a common clinical disease, often accompanied by motor dysfunction and cognitive impairment. At present, clinical treatment for patients with ischemic stroke recovery is limited and ineffective. The emergence of NGF has surprised the field of neurorehabilitation, but the clinical effect is not satisfactory. The main problem is that NGF is a macromolecular material with a molecular weight of 13.4 KD, which is difficult to penetrate the blood brain barrier. A large number of previous studies in our team have found that electroacupuncture with specific stimulation mode can open the blood brain barrier and induce NGF into the brain。Therefore, the purpose of this study is to investigate the effect of specific stimulation mode electroacupuncture combined with NGF treatment together with rehabilitation training on patients with ischemic stroke recovery period and to explore the mechanism of this combination therapy to improve brain function, which creates a new method and theoretical basis for nerve rehabilitation of integrated traditional Chinese and Western medicine.

Chronic mesenteric ischemia (CMI) is often caused by narrowings in the arteries providing blood to the intestines. Endovascular stent placement is considered the preferred treatment for this condition. Guidelines increasingly support the use of so called covered stents (CS) in stead of bare stents (BMS) for this use but the level of evidence for this is limited. Using CS incur additional costs for healthcare short-term but may prevent recurrence of narrowing and symptoms postoperatively benefitting patients and healthcare. Study Objective: To evaluate the outcomes after stenting of mesenteric arteries using BMS or CS. Study Outcome: Primary stent patency 1 year after placement The trial will also evaluate complications, how often stents need to be reoperated, Quality of Life (QoL) and reasons for subjects death Method: This is a so called prospective, randomized controlled trial comparing CS vs. BMS. This means that one patients have agrred to treatment they will be randomly selected for treatment with either CS or BMS . The stent metal structure is identical in the two implants and the only difference is the graft covering, making this study unique. The study will also collect blood samples for a biobank that will be used to study markers of disease and how these effect treatment outcomes. All patients referred to the Department of Vascular Surgery due to CMI are considered for inclusion if they havechronic symptoms consistent with CMI, significant stenosis or occlusion of the superior mesenteric artery and are > 18 years Subjects not able to provide informed consent or who have non atherosclerotic cause of CMI, signs of acute loss of blood flow to the intestines cannot participate. Previous stent treatment in the superior mesenteric artery, pregnancy, allergies to contrast or stent materials are also reasons for not being included in this trial. Side effects, risks and disadvantages for participants The risk for procedure-related complications is less than 5% and similar in both study groups. Most short-term complications are related to vascular access sites and consist of local bleeding and thrombosis. Other potential complications include impaired renal function due to contrast use, contrast allergy, arterial dissection and death.

There is a lack of complex studies which could establish the association between genetic circadian factors with the features and short-term outcomes of ischemic stroke, as well as the effects of various auxiliary therapies for circadian rhythm modulation for neuroplasticity enhancement and improvement of short-term outcomes in ischemic stroke. The main research hypothesis is that circadian factors influence the recovery from ischemic stroke via sleep-mediated regulation of synaptic plasticity. The project aims at the investigation of the influence of combined melatonin therapy and blue light exposure on molecular circadian biomarkers, sleep characteristics, neuroplasticity markers and stroke outcome in acute stroke patients. This study is a prospective, interventional, randomized placebo-controlled trial.
