Cerebral Arteriovenous Malformation With Aneurysm: Epidemiology, Clinical Features, and Prognosis

The study is a multicenter, prospective cohort study designed to assess the natural history, clinical safety and efficacy of various treatment strategies in patients with cerebral arteriovenous malformations (AVMs) and intracranial aneurysms.

Ultra-Early, Minimally inVAsive intraCerebral Haemorrhage evacUATion Versus Standard trEatment

A randomized controlled trial of ultra-early, minimally invasive, hematoma evacuation versus standard care within 8 hours of intracerebral hemorrhage. Patients presenting to the emergency department with stroke due to supratentorial, spontaneous intracerebral hemorrhage \>20mL volume will be assessed to determine their eligibility for randomization into the trial. If the patient gives informed consent they will be randomized 50:50 using central computerized allocation to minimally invasive hematoma evacuation using the Aurora surgiscope and evacuator (Integra Lifesciences) versus standard medical therapy. The trial is prospective, randomized, open-label, blinded endpoint (PROBE) design with seamless phase 2b-3 transition if the intermediate endpoint (successful hematoma evacuation) is met in analysis of the first 52 patients. Adaptive sample size re-estimation (Mehta and Pocock) will be performed when 160 patients have completed 6 month follow-up (minimum sample size 240, maximum sample size 434).

REpeated ASSEssment of SurvivorS in Intracerebral Hemorrhage Study

The investigators propose to perform serial detailed cognitive, motor, behavioral, and blood collection follow-up using longitudinal structured telephone interviews of an anticipated 350 ICH survivors enrolled in Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation (MISTIE) III and ENRICH trials to identify specific cognitive and motor impairment and to perform RNA sequencing to evaluate for evidence of chronic inflammation. The investigators' expected sample size in 2022 accounts for mortality attrition of 10%/year.

Recovery of Consciousness Following Intracerebral Hemorrhage

The objectives of the RECONFIG clinical study are to : 1. To identify the time to the first diagnosis of cognitive motor dissociation (CMD) in intracerebral hemorrhage (ICH) patients and to investigate whether these patients will clinically follow commands earlier after the hemorrhage. 2. To determine whether CMD independently predicts long term functional outcomes (6-month mRS scores) in ICH patients, and is associated with long term cognitive and quality of life outcomes. 3. To determine the EEG response to verbal commands of the motor imagery paradigm between patients with and without sensory aphasia. The overall goal is to determine predictors and the trajectory of neurological recovery.

Influence of Cerebral Oedema in Intracerebral Haemorrhage

In 2020, IntraCerebral Haemorraghe (ICH) remains the most devastating type of stroke. Besides stroke unit care, no specific treatment has been proven effective yet. Perihaematomal oedema (PHO) could be a promising therapeutic target. However, the mechanisms, the natural history as well as the clinical impact of this PHO remain unclear. The COPITCH study has been designed to answer these questions

Maximal Medical Treatment of Intracerebral Haemorrhage Pilot Trial - MAX-ICH Pilot Trial

The MAX-ICH pilot trial is a phase-II study aimed at assessing the feasibility and safety of a comprehensive care bundle for patients with intracerebral hemorrhage (ICH). This "maximal medical treatment" approach combines advanced interventions like intensive blood pressure control, rapid anticoagulation reversal, and tranexamic acid administration to potentially improve outcomes. The primary objective is to evaluate recruitment feasibility over 12 months, while secondary objectives include protocol adherence, safety monitoring, and the exploration of clinical outcomes. The study focuses on the critical first 72 hours of care to determine if this approach can be effectively implemented in clinical practice.

Predicting Outcomes in ICH Patients on Direct Factor Xa Inhibitors

This study focuses on direct factor Xa inhibitors (apixaban, edoxaban, rivaroxaban) and the thrombin inhibitor dabigatran, commonly used for stroke prevention in atrial fibrillation. Despite lower intracranial bleeding risks with these drugs, around 0.2-1.0% of patients annually experience intracranial hemorrhage (ICH), predominantly intracerebral. Treatment options for factor-Xa inhibitor-associated ICH, such as prothrombin complex concentrate (PCC) and andexanet alfa, lack direct comparison evidence except for ongoing trials like ANNEXA-I. This trial assesses hemostatic efficacy and 30-day functional outcomes but leaves gaps regarding anticoagulant activity's role and long-term effects, especially in patients presenting late after drug intake. The measurement of anti-FXa levels helps guide decisions, yet their link to hematoma expansion remains unknown. Efforts to streamline measurement within 30 minutes for acute decisions have shown variability in levels, with some patients exhibiting high levels even beyond 12 hours post-intake. This lack of data poses challenges, particularly for patients potentially benefiting from treatment beyond the current strict time window. Early hematoma expansion strongly predicts poor outcomes, but preventing it faces challenges like recurrent events (up to 5% by 3 months) and rehabilitation intensity, potentially negating its benefits. The ANNEXA-I trial evaluates short-term outcomes, highlighting the need for additional data to comprehend long-term ICH prognosis. The study's objectives involve linking hematoma expansion to anti-FXa levels, determining late-presenting patients' risk of expansion, and identifying predictors of favorable outcomes at 3, 6, and 12 months. Primary endpoints include functional outcomes, while secondary ones encompass expansion rates, anticoagulant activity, and various events at 12 months. This research aims to bridge gaps in understanding factor-Xa inhibitor-related ICH, addressing both immediate and prolonged outcomes to enhance clinical decision-making.

Intracranial Pressure and Optic Nerve Sheath Diameter With CLOSED Bundle

The design of the present study will be a multicenter prospective observational protocol. Approximately 100 patients will be recruited over the 24-month period with Acute Brain Injury (trauma brain injury, intracerebral hemorrhage, subarachnoid hemorrhage, ischemic stroke), who in their acute phase of intensive care unit require placement of a catheter capable of monitoring intracranial pressure (intra parenchymal catheter or external ventricular shunt). In addition to all the intensive care provided by the most recent guidelines, patients will undergo measurement of optic nerve sheath diameter through ultrasonography. At least, three measurements will be performed within the first 3 hours after admission, within the first 24-48 hours, and at each invasive intracranial pressure value greater than 18 cmH2O. Those patients with intracranial pressure values greater than 35 mmHg. At the first intracranial pressure measurement, patients with eyeball disease or trauma will be excluded. Measurements will be performed following the CLOSED bundle. Analysis of the results will include correlation between the invasive pressure values and the mean value of optic nerve sheath diameter measurements in the two projections (sagittal and transverse). In addition, the correlation of the absolute value of invasive pressure detected with the ratio of the optic nerve sheath diameter measurement to the eyeball diameter measured always ultrasound will be sought.
