Active clinical trials for "Intracranial Hemorrhages"

This is a three-year pre- and post- interventional study to assess the effectiveness of collaborative quality improvement interventions on reducing mortality and severe intracranial hemorrhage (ICH) for neonates receiving extracorporeal life support (ECLS) in China.

The multicenter, prospective, observational, non-interventional study conducted in German Stroke Units is investigating patients with intracranial hemorrhage (ICH) under effective anticoagulation with rivaroxaban or apixaban. The aim of the study is to analyze under routine conditions wether the volume increase of ICH under treatment with rivaroxaban and apixaban can be reduced with the antidote andexanet alfa. Thus, data of patients under effective treatment with rivaroxaban or apixaban and treated with andexanet alfa at baseline will be assessed at the time of onset of ICH, during the hospital stay and during a follow-up by telephone at 30 and 90 days after hospital discharge. The main objective is defined as the change in size or volume of the hematoma by computed tomography (CT) or magnetic resonance imaging (MRI) in patients with ICH under effective treatment with rivaroxaban and apixaban, who are treated with andexanet alfa. Further objectives comprise evaluations concerning the functional status according to modified Rankin Scale (mRS), changes in the National Institutes of Health Stroke Scale (NIHSS), and occurrences of ICH or new intraventricular bleeding as well as mortality rates.

Intracranial Hemorrhage (ICH) is an important morbidity affecting premature infants and can have considerable effects on neurodevelopmental outcome. The investigators showed that preterm infants with severe ICH have decreased cerebral oxygenation several weeks after the hemorrhage. The mechanisms involved in this state of decreased cerebral oxygenation in preterm infants and the effects on cerebral function are unknown. This longitudinal observation study will evaluate physiologic parameters to determine trends in cerebral oxygenation and function in preterm infants with ICH in comparison to infants without ICH.

In this study, investigators look at a different type of technology that might help to avoid having to perform CT scans in certain patients suspected of having a head injury. Near-infrared spectroscopy (NIRS) uses a specific light wavelength to determine if there is bleeding into the head as a result of trauma. Investigators will study NIRS, using a device called the Infrascanner model 2000, to determine if it is as good at detecting bleeding in the head as CT scan, which is the current gold standard. Investigators will try to determine if NIRS can rule in or rule out bleeding into the head, and perhaps this can help to avoid subjecting these youth to the potentially harmful effects of radiation. Investigators will also study how easy it is to use NIRS so that it might become a standard part of the workup for children with suspected head injury.

The purpose of this study is to determine whether treatment with remote ischemic conditioning is of sufficient promise to improve outcome before conducting a larger clinical trial to examine its effectiveness as a treatment for intracerebral hemorrhage.

Intracranial hemorrhage (ICH) can occur due to traumatic and spontaneous events.1 The incidence of non-traumatic, spontaneous ICH is approximately 40,000 to 67,000 cases per year while the incidence of traumatic brain injury (TBI) is nearly 1.7 million annually

In this project the investigators study the safety and efficacy of the pipeline embolization device with vantage technology in treatment of unruptured brain aneurysms

Primary Objective: To identify the optimal interval to restart oral anticoagulation after traumatic intracranial hemorrhage that will minimize thrombotic events and major bleeding by performing a response adaptive randomized (RAR) PROBE clinical trial of restarting in anticoagulant-associated traumatic intracranial hemorrhage patients, comparing restart at 1 week to restart at 2 weeks or at 4 weeks, with a primary composite outcome of major thrombotic events and bleeding. Primary Outcome: 60-day composite of thromboembolic events, defined as DVT, pulmonary emboli, myocardial infarctions, ischemic strokes and systemic emboli, and bleeding events defined as non-CNS major bleeding events (modified BARC3 or above) and worsening index tICrH or new intracranial hemorrhage (ICrH). Secondary objectives of this trial include: To use the Trauma Quality Improvement Program (TQIP) of the American College of Surgeons - Committee on Trauma (ACS-COT), a well-established and highly respected trauma center oversight mechanism, to translate findings of the trial into practice in a closed loop. To establish a relationship between time of restarting and overall secondary events, i.e. a dose response, that favors early restarting (1 week is better than 2 weeks and 2 weeks is better than 4 weeks. To explore patient centered utility weighting of thrombotic versus bleeding composite endpoint components by: A) 60-day Disability Rating Scale (DRS) 24,25 and modified Rankin Scale (mRS)26; B) Trial patient-reported standard gamble utilities including by race, gender and ethnicity. To explore the composite without DVT in the thrombotic component

This study is the first and largest secondary prevention trial about lipid-lowering therapy for acute ischemic stroke patients at high-risk of intracranial hemorrhage. The primary hypothesis of this study is: excessive reduction in serum lipid levels by intensive statin therapy in acute ischemic stroke patients with cerebral microbleeds can increase the risk of intracranial hemorrhage. This study will shed light on new clinical decisions regarding the long-term serum lipid management in these patients with dilemma in clinical practice.

The goal is to derive and a clinical decision rule for safe exclusion of traumatic brain injury without neuroimaging in head-injured ED patients who take anticoagulant medications. The objectives are to: Derive and externally validate a new highly sensitive and maximally specific clinical decision rule for the exclusion of traumatic brain injury in head-injured ED patients who take anticoagulant medications; and, Estimate the sensitivity and specificity of existing head injury clinical decision rules in head-injured ED patients who take anticoagulant medications.
