Active clinical trials for "Intracranial Hemorrhages"

This is a pilot study to evaluate clinical predictors of intracranial bleeding in elderly patients who present to the emergency department (ED) after a fall. The aim is to assess feasibility and rate of patient recruitment, patient follow up, and to establish a point estimate for the incidence of intracranial bleeding in the investigator's population. Currently there are no guidelines for ED physicians to assess the pretest probability of intracranial bleed in these patients, and no safe way to exclude a bleed without CT.

Falls are the leading cause of traumatic death in the elderly with head injury causing half of these deaths. Each year, one in three adults over the age of 65 (seniors) fall, and half of these seniors seek treatment at a hospital emergency department (ED). There is a major evidence gap in the study of brain injury diagnosis in seniors, which is problematic for emergency physicians since the number of fall-associated head injuries is rising. ED diagnostic tools for risk stratification of these patients do not exist. The investigators will derive a novel ED clinical decision rule for detecting traumatic intracranial bleeding which will standardize the approach to head CT scans. Once validated, the investigators will optimize patient care by ensuring that intracranial bleeding is identified early. By reducing the use of head CT, this decision rule will lead to health care savings and streamlined, patient-centered ED care.

Randomized pilot trial of restarting DOACs at 1 week versus 4 weeks after traumatic intracranial hemorrhage

A Prospective Randomized Open-Label Blinded Endpoint (PROBE) Pilot Trial of restarting antiplatelet therapy at 1 week versus 3 weeks after traumatic intracranial hemorrhage with a primary composite endpoint of major bleeding and vascular occlusive events.

The aim of the study assesses static and dynamic cerebrovascular autoregulation daily over one week in patients with traumatic brain injury or intracranial hemorrhage to quantify the temporal profile of the autoregulatory status.

The primary aim of the study is to investigate the relationships among FVIII, t-PA/PAI-1, MMP-9 levels, and intracranial hemorrhage after thrombolysis with alteplase using a combined analysis.

Dysregulation of autonomic nervous system is evident in patients with spontaneous intracranial hemorrhage. In this study, we utilize a non-invasive method (heart rate and blood pressure variability analysis to analyze the autonomic activities in this group of neurosurgical patients. Our aim is to determine the utility of this modality in risk stratification and outcome prediction in these patients.

Intracranial hemorrhage despite being rare, several chronic ITP patients experience moderate to severe behavioral problems including learning difficulties, memory affection .These changes could be due to the presence of minute capillary dysfunction

Florbetapir F 18 is an experimental radioactive drug that may allow doctors to image changes in the brain using a PET (Positron Emission Tomography) scanner. The purpose of this study is to evaluate the imaging characteristics of, Florbetapir F 18 (also known as 18F-AV-45) in patients who have previously undergone bleeding in their brains. Florbetapir F 18 binds to amyloid-ß peptide (Aß) that accumulates in the brains of patients with bleeding. These accumulations are called amyloid plaques and when extensive are labeled cerebral amyloid angiopathy (CAA). Florbetapir F 18 sticks to the amyloid plaques in the brain and emits a low level of gamma rays which can be detected by a PET camera. MRI detected microbleeds have been identified as markers of clinically silent hemorrhage from bleeding-prone vessels. Another imaging marker of vessel damage and risk of bleeding is the spot sign (SS). Finally, certain genetic signatures (ApoE genotype) have been shown to be associated with Aß deposition in the brain or predispose patients to higher risks of bleeding. This research study will explore the interactions of these factors and understand the physiology of intracerebral bleeding.

Intracranial hemorrhage is is a rare, but critical incident in patients with acute lung failure undergoing ECMO therapy. Predictors of intracranial hemorrhage are yet to be defined to identify patients at (high) risk. This retrospective analysis investigates the predictive value and validity of parameters and specific risk factors of critically ill ARDS patients treated with ECMO.
