Active clinical trials for "Intracranial Hemorrhages"

Background: Despite the capability of emergency surgery to reduce the mortality of severe spontaneous intracranial hemorrhage (SSICH) patients, the effect and safety of surgical treatment for severe spontaneous intracranial hemorrhage (SSICH) patients receiving long-term oral antiplatelet treatment (LOAPT) remains unclear. In consideration of this, the cohort study is aimed at figuring out the effect and safety of emergency surgery for SSICH patients on LOAPT. Methods: As a multicenter and prospective cohort study, it will be conducted across 7 representative clinical centers. Starting in September 2019, the observation is scheduled to be completed by December 2022, with a total of 450 SSICH patients recruited. The information on clinical, radiological, and laboratory practices will be recorded objectively. All of the patients will be monitored until death or 6 months after the occurrence of primary hemorrhage. Study Design: In this study, two comparative cohorts and an observational cohort will be set up. The primary outcome is the effect of emergency surgery, which is subject to assessment using the total mortality and comparison in the survival rate of SSICH patients on LOAPT between surgical treatment and conservative treatment. The second outcome is the safety of surgery, with the postoperative hemorrhagic complication which is compared between the operated SSICH patients on and not on LOAPT. Based on the observation of the characteristics and outcome of SSICH patients on LOAPT, the ischemic events after discontinuing LOAPT will be further addressed, and the coagulation function assessment system for operated SSICH patients on LOAPT will be established. Objective: In this study, investigators will estimate the effect and safety of emergency surgery for SSICH patients on LOAPT, which will provide an evidence for management in the future.

The overall purpose of this study is to evaluate how effective Thromboelastography (TEG) is on identifying ischemic and hemorrhagic stroke patients at increased risk for bleeding after receiving tissue plasminogen activator (tPA), as well as on differentiating between patients in whom optimal thrombolysis has been achieved, and those whom it has not.

The present study will monitor and explore acute neurovascular emergencies in patients treated with NOACs compared to those under treatment with VKAs. The primary aims of this study are: (1) To investigate characteristics, management and outcome of intracranial hemorrhage (ICH) in patients treated with NOAC compared to VKA. (2) To investigate the management and outcome of patients with acute ischaemic stroke under NOAC compared to VKA.

Observational study to investigate the natural course of intracranial pressure (ICP) after decompressive craniectomy (DC) using long-term telemetric ICP monitoring. Patients will have continuous ICP measurement performed during the admission to the neuro-intensive care unit (NICU) and after discharge weekly measurements sessions will be performed before and after cranioplasty.

The purpose of this program is to develop a regional integrated stroke system that identifies, classifies, and treats patients with acute ischemic stroke more rapidly and effectively with reperfusion therapy.

This multicenter, prospective, observational, non-interventional study investigates patients with intracranial hemorrhage under effective anticoagulation with dabigatran or vitamin-K antagonist (VKA). Routine data will be collected during hospitalization. Patients aged 18 years or older under effective therapy with dabigatran and symptomatic intracranial bleeding confirmed by cerebral imaging and treated with idarucizumab will be compared to patients under effective treatment with VKA at the time of onset of the intracranial bleeding. Ninety-five dabigatran patients who provided written informed consent for data transmission will be included. As control group retrospective and anonymized data of 285 VKA patients patients under VKA treatment and admitted to RIC-ICH study centers will be used. For each patient receiving idarucizumab, three patients with intracranial hemorrhage under effective treatment with VKA, will be included (retrospective) in the study. In addition, data of VKA patients will be transferred from the RASUNOA-PRIME and the "Erlanger Hirnblutungs-Register".

The new Integra CereLink ICP monitor integrate the possibility of recording and displaying continuously the AUC (Pressure Time Dose, PTD) and other ICP derived variables and provide the possibility of evaluating the utility of this information at the bedside. It offers the opportunity to test in a standardized way the clinical value of the PTD computation in this setting. Therefore, this study aims to test clinically if PTD recorded continuously is associated to patients' outcome and to identify a threshold of PTD associated with the transition from good to negative outcomes.

By combination of plasma (Aβ40, Aβ42, total tau, and phosphorylated tau, etc.), genetic (ApoE ε2 or ε4 allele), MRI (cerebral perfusion, microbleeds, cortical superficial siderosis, enlarged perivascular space, etc.) and PET imaging (amyloid and tau) biomarkers, the study aims to Enhance the diagnostic potentials of the radiological biomarkers by combining MRI and amyloid PET in CAA patients. Investigate the biological pathogenesis in CAA patients using the less invasive plasma biomarkers and to correlate with structural and function imaging, including MRI, amyloid and tau imaging. Study the characteristics of long-term progression of amyloid deposition in CAA patients using the radiological, biochemical and genetic biomarkers. Study the prognosis predicting markers.

The true incidence and risks of intracranial hemorrhage (ICH) in patients on various antithrombotic treatments remain unknown. Here a nationwide study is conducted to investigate the risk for and incidence rates of ICH in users and non-users of various oral antithrombotic drugs in Norway between 2008 through 2014. Hopefully, this study will contribute to a more responsible prescription pattern of antithrombotic medications.
