Active clinical trials for "Intracranial Hemorrhages"

Glioma patients with history of venous thromboembolism (VTE) treated on low molecular weight heparin (LMWH) and who decided with their physician to convert to Apixaban (oral drug) will be enrolled into our study and will collect data regarding recurrent VTE and Intracranial hemorrhage and the incidence of these events.

Context: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. The aim of this project is to reduce the delay of the diagnosis of brain death, and also to improve its diagnosis in the Intensive Care Unit. The diagnosis of brain death is strictly defined by the law and relies either on two consecutive flat electroencephalograms recorded at an interval of four hours, or on the lack of cerebral circulation during a brain angiography performed after suspecting brain death on the clinical exam. However, in usual practice, it is difficult to have all the needed clinical arguments, and their interpretation can be difficult in the pathological context. This may participate in the delay and the lack of patients potentially donors. Pre-study: In a pilot study, fifty subjects with severe cerebral lesions, had a continuous ECG recording. The investigators could find that a decrease in autonomic nervous system activity, as measured through the ECG, was correlated to the transition to brain death assessed by cerebral angiography. The loss of cardiac variability was always observed between two cerebral angiographies, one before and the second after brain death. This study allowed the investigators to calculate the threshold values of sympathetic and parasympathetic activities to confirm brain death.

Management of traumatic brain injuries causes significant efforts on emergency departments (ED) and overall health care. Patients on antithrombotic treatment with even minor trauma to the head, although without significant clinical findings, represent special challenges because the risk of traumatic intracranial hemorrhage (tICH) with these agents. The aim of this study was to compare the prevalence of tICH in patients on various pre-injury antithrombotic treatment exposed to minor Traumatic Brain injuries (mTBI) in Sundsvall with untreated patients. Secondary aim was to explore different risk factors for tICH. Data from medical records and radiology registry with mTBI in Sundsvall hospital between 2018-2020 in Sundsvall identified 2044 patients. Demographic data, pre-injury medications with antithrombotic treatment, state of consciousness at admission and the results of CT-scans of brain was investigated.

The study will examine the resting energy need (REE) in patients suffering from brain damage. For the measurement of REE will be used a metabolic computer (which with continuous recording of breath-to-breath volume (Vt), respiratory rate (RR) of ventilation per minute volume (MV) ), of inhaled and exhaled gases (O2 and CO2) has the ability to calculate the values of VO2, VCO2 and with the help of equations the values of REE and RQ.

What happens in the borderzone of a cerebral hemorrhage remains widely onknown and furhter the best timing for doing MR to look for vascular pathology in cerebral hemorrhage has not yet been determined. In this study we do acute MRS, a non-invasive imaging mathod to detemine the biochemsty in the border zone and structural MRI for vascular malformation. We repeat structural MRI after 8 weeks.

Currently, when premature infants develop severe intraventricular hemorrhage (IVH), a type of intracerebral bleed, there are no proven therapeutic interventions to prevent the devastating consequences of this event. These children will be likely to develop cerebral palsy or severe cognitive delays. The purpose of our study is to characterize differences in brain physiology, imaging, and function between premature infants with severe IVH and controls. The goals for gathering this information are to generate baseline data, which could facilitate early screening for complications of IVH in premature infants. These baseline data would also allow the design and implementation of early therapeutic interventions to help rehabilitate premature infants with severe IVH.

Introduction and Aims: The objective of this prospective study is to evaluate the risk factors of minor head injury in all consecutive patients of one year.

Abstract Purpose Patients with anticoagulation therapy has a higher risk of developing traumatic Intracranial Hemorrhage (tICH). Delayed Intracranial Hemorrhage (d-ICH) is a rarer clinical manifestation; however, the incidence varies from 0-9,6 % in other studies. Some studies have also questioned the clinical relevance of d-ICH, since the mortality and the need of neurosurgical intervention is reported to be very low. The aim of this study is to determine the incidence of d-ICH at Sundsvall Regional Hospital. Methods A retrospective observational study of patients with mTBI and oral anticoagulation therapy. Data from medical records and radiology registry in Sundsvall hospital for 29 months during 2018-2020 in Sundsvall identified 249 patients with an initial negative CT scan who performed a follow-up CT scan. Outcome measure was incidence of d-ICH.

Intracranial pressure is usually measured by invasive methods requiring an intracranial sensor. There is no non-invasive monitoring method recognized as a gold standard. Tympanometry would make it feasible to evaluate intracranial pressure through sensitive and specific changes in the energy absorbance of the middle ear. It could represent a non-invasive method of monitoring intracranial pressure. This is a prospective monocentric longitudinal study. All adult patients in intensive care for head trauma, intracranial hypertension, or after cranial surgery and requiring invasive monitoring of ICP will be included after their non-opposition has been collected. In a group of 10 controls, multifrequency tympanometry will be performed in the standing position, in the 0° supine position and in the Tredelenburg position at -17°.

The purpose of this investigator-initiated study is to compare the use of pupilometer and ultrasound assessment of optic nerve sheath diameter in predicting the ICP and to see if there is a value that could be used to indicate elevated ICP with either modality as these numbers are inconsistent throughout the literature. Patients that have either an external ventricular drain (EVD) or bolt placed will be enrolled in the study. After the EVD and bolt are placed the patient will undergo pupilometer examination (standard of care) followed by ultrasound assessment of the optic nerve sheath diameter (ONSD). The three values will be recorded. The same patient may have multiple readings performed if there is a change in ICP either spontaneously or due to intervention.
