Active clinical trials for "Cerebral Infarction"

During clamping of one internal carotid artery for endarterectomy, blood flow through this vessel has to be compensated by collateral arteries including the contralateral internal artery and vertebral arteries. In 7 % of all patients undergoing carotid endarterectomy this collateral flow is not sufficient to maintain adequate cerebral perfusion during clamping and ischemic brain damage is likely to emerge. To maximize cerebral blood flow during clamping, increase of blood pressure is a common procedure and routine at our institution. Increasing blood pressure can be enabled by tapering a mixture of Cafedrine und Theodrenalin (Akrinor®) until the designated blood pressure is reached. After declamping, the blood pressure has to be reduced to normal values to avoid postoperative hyperperfusion syndrome. This is enabled by tapering urapidil until normal blood pressure is achieved. It has been shown that cerebral oxygenation measured by near infrared spectroscopy is reduced by intravenous application of norepinephrine. Otherwise, intravenous nitroglycerine increases cerebral oxygenation during cardiopulmonary bypass. Hence, cafedrine/theodrenalin and urapidil may also have an effect on cerebral perfusion. In this prospective randomized study the effect of cafedrine/theodrenalin and urapidil on cerebral oxygenation measured by near infrared spectroscopy is investigated.

This study is being conducted as a feasibility clinical investigation to collect safety and technical performance data of the WOLF Thrombectomy Device for the removal of thrombus in the neurovasculature.

The investigators hypothesize that earlier initiation of edoxaban in AF-related stroke patients may significantly reduce the early recurrence of ischemic stroke, compared with conventional strategy of anticoagulation following 1-3-6-12 rule. To expedite the verification of the hypothesis, the investigators are planning to use diffusion weighted imaging (DWI), which has been reported to be a surrogate to predict both short-term and long-term prognosis after stroke, to detect the recurrent ischemic events. Because data on the early anticoagulation in patients with AF-related stroke are limited, the investigators decided to perform a pilot study before establishing an appropriate clinical trial protocol. This study will help estimate the efficacy and safety of early administration of edoxaban, and determine the sample size of a following clinical trial. To ensure the safety in this pilot exploration, the investigators will not include patients with severe ischemic strokes, who are often prone to experience hemorrhagic transformation in the acute post-stroke period.

This is a randomized, controlled, active comparator arm, outcome assessor blind, parallel group design on 90 patient with diagnosis of ischemic stroke admitted in Bou-Ali Sina Hospital, Sari,Iran.The aim of study is assess the efficacy of ticagrelor plus aspirin in reduce of minor non-cardioembolic ischemic stroke or high risk TIA recurrence during first 3 months.

This study is designed to evaluate the safety, efficacy, and pharmacokinetics of balovaptan compared with placebo in participants with acute ischemic stroke (AIS) at risk of developing Malignant Cerebral Edema (MCE)

The African-American Antiplatelet Stroke Prevention Study is designed to prevent recurrent strokes by administration of aspirin or ticlopidine. The study also provides community information on reducing risk of stroke and recognizing the symptoms of stroke. The study involves more than 50 participating hospitals located throughout the United States. Study medication is provided free of charge, and a transportation stipend is available for those in need.

Dapsone is a drug that has been used clinically for several decades due to its anti-infective effect, making it widely available. Its neuroprotective effects have been found through its glutamate receptors antagonistic effect. Their main objective was to study the neuroprotective properties in patients with aneurysmal subarachnoid hemorrhage and high-risk factors for the development of cerebral vasospasm. Both the placebo and the dapsone used in this clinical trial were provided by the institution's neurochemistry laboratory.

The purpose of this study is to evaluate the effects of hypercapnia on hemodynamics and cerebral oxygenation during shoulder arthroscopy.

To examine the efficacy and safety of dual antiplatelet therapy (DAPT) including cilostazol (Pletaal OD Tablet ®) in comparison with antiplatelet monotherapy (excluding cilostazol) for secondary prevention of ischemic stroke in high-risk patients for stroke

The purpose of this study is to assess the efficacy and safety of Naoxintong Capsule in the secondary prevention of ischemic stroke by the multi-center, randomized,double-blind，placebo-controlled trial design project.
