Preventing Recurrences of Chronic Subdural Hematoma in Adult Patients by Middle Meningeal Artery...
HematomaSubdural1 morePatients with a chronic subdural hematoma (cSDH), that is, a blood accumulation between two meninges developing over a long period of time, often have recurrent bleedings after an initial operation. The study aims to show that additional surgery reduces the risk of recurrent bleeding. The additional procedure aims to block small blood vessels in the skull with tiny plastic particles. The small blood vessels are embolized using X-rays and a contrast medium and a fine tube that is inserted into the diseased vessels of the head via the groin. Patients of full age who have undergone burr hole trepanation as a first operation, i.e. a blood drain through a hole in the cranial cavity, can participate in the study. Participating patients are randomly assigned to a control group with treatment according to clinical routine or a treatment group with an additional occlusion of the blood vessels in the skull. In addition, patients can consent to a genetic test to determine the relationship between a coagulation factor and the risk of recurrence of the hematoma. In order to record the test results, check-up examinations are carried out after one and three months.
Augmented Reality for Subdural Drain Placement
Subdural HematomaThis study involves using a augmented reality (AR) system to assist in the placement of a subdural evacuating portal system (SEPS). In the first part of the study, all participants will have skin marking of an AR-guided and non-AR-guided site to determine feasibility and method accuracy. In the second part, subjects will be randomized to AR-guided and non-AR-guided SEPS placement to determine efficacy.
High Concentration Oxygen Therapy for Pneumocephalus in Chronic Subdural Haematoma: A Prospective...
Chronic Subdural HematomaNormobaric oxygen therapy was shown to be effective in reducing post craniotomy pneumocephalus. Theoretical assessment of normobaric oxygen therapy in treating pneumocephalus has shown that a higher level of oxygen concentration will significantly decrease the time for absorption of pneumocephalus. The therapeutic efficacy is not fully established in patients with chronic subdural hematoma after burr hole drainage. Both radiological outcomes and clinical outcomes would be evaluated.
Patient Registry for Patients With Chronic Subdural Hematoma
HematomaSubdural Hematoma1 moreAll admitted patients diagnosed with unilateral or bilateral chronic subdural hematoma are included into this registry after consent. Clinical condition, radiological details, therapy (intervention/medication treatment/conservative) and outcome are documented. Patient follow-up is documented over at least 24 month with focus on neurological condition (NIHSS), cognitive impairment (MoCA) and quality of life (SF-12 ver. 2).
The Use of Tranexamic Acid in the Treatment of Symptomatic Subdural Hematoma
Subdural HematomaSubdural hematoma (SDH) is a common condition experienced after head injury. Blood collects on the surface of the brain, causing headaches which can progress to confusion, weakness, or even coma. While patients with SDH often receive surgery, not all patients require surgery right away to ease pressure on the brain. After surgery, there can be up to 30 percent chance of more bleeding and the need for more surgeries. Given this, a drug capable of lowering the chance of more bleeding and speeding the recovery of the patient is highly desirable. In this study, we will test a commonly used, cheap drug called Tranexamic Acid (TXA). While the body stops unwanted and sometimes dangerous bleeding naturally by forming blood clots, TXA stops these blood clots from breaking down, which helps to keep bleeding spots plugged. Our previous study showed that TXA helped speed up patients' recovery; but a larger number of patients is necessary to evaluate how well TXA works to reduce bleeding and improve patient-reported outcomes. In this study, regardless of the need for surgery, half of the patients will be randomly assigned to take TXA, while the other half will take a placebo, which is a look-alike substance that contains no active drug. We will measure multiple outcomes over time to determine if TXA is working and lowers healthcare and personal costs, while also taking blood and surgical samples, to better understand how this drug works in SDH patients.
Prospective Study on the Use of Middle Meningeal Artery Embolization for Chronic Subdural Haematoma...
Chronic Subdural HematomaSubdural HematomaSubdural haematoma is a common neurosurgical condition that results in different levels of neurological deficits in patients. It can be further classified into acute and chronic, which have different pathophysiology. Acute haematoma is a common result of traumatic injuries involving the tearing of the bridging veins, while chronic subdural haematoma can be both a result of traumatic injuries or recurrence following surgical management of the acute counterpart. For symptomatic patients, they are often surgically managed by haematoma drainage via burr-hole drainage and craniotomy. Recurrent bleeding following close monitor or surgical evacuation of haematoma is however very high. Recent studies approximate the recurrence rate of 2%-33.3%. Recent evidence suggests the angiogenesis of middle meningeal arteries (MMA) in response to inflammation and healing process contributes to the development of chronic subdural haematoma, and its high recurrence chance. Several studies have looked into the use of middle meningeal artery embolization to halt the bleeding of a chronic subdural haematoma, and have found promising results in terms of haematoma reduction and prevention of surgical rescues.
Tranexamic Acid in the Treatment of Residual Chronic Subdural Hematoma -2
Chronic Subdural HematomaChronic subdural hematoma (CSDH), a common disease after minor head trauma, is characterized by blood collection in the subdural space, which can result in severe neurological impairment. The current standard of care is the surgical evacuation of CSDH. Although clinical and surgical outcomes are satisfying in most cases, considerable morbidity, mortality and recurrence rates of 3-31% are frequently reported. Therefore a non-surgical approach to treat CSDH is desirable. Tranexamic acid (TXA), an antifibrinolytic drug, has been shown to decrease hematoma volume in a small cohort of CSDH patients. The present study is designed to test the hypothesis that TXA can reduce the volume of CSDH. Volume measurements of residual CSDH after burr-hole surgery will be performed to quantify treatment success. The trial is designed as a double-blinded randomized controlled trial, where half of the patients will be assigned to daily intake of TXA, whereas the other half will receive placebo. The primary endpoint is defined as volume change in milliliter after 4-8 weeks of treatment. Secondary endpoints are hematoma volume at 8-12 weeks, patient safety, the number of patients with resolution of the CSDH after 4-8 and 8-12 weeks of study participation, the neurological outcome, the rate of reoperation, the time to reoperation, drug safety and compatibility, and participant quality of life (QOL).
Defining Core Outcomes and Data Elements (CODE) in Chronic Subdural Haematoma
Chronic Subdural HematomaThis study is aimed at improving reporting in Chronic Subdural Haematoma (CSDH) research studies, through development of a standardised Core Outcome Set (COS), a unified CSDH Definition and set of Data Elements (DE) for reporting. The study design includes a Delphi survey process from two main stakeholder groups: Health-Care Professionals or Researchers (HCPR) and Patients or carers. HCPR, patients and carers will all be invited to complete the survey on the COS, only the HCPR survey will include questions on definition and DE. Results of the Delphi Survey will be discussed at a final consensus meeting before results are confirmed and published.
Neurologic Deficits and Recovery in Chronic Subdural Hematoma
Chronic Subdural HematomaChronic subdural hematoma (cSDH) is one of the most common problems treated by neurosurgeons, particularly as the population ages. While often dismissed as a benign problem, it has become clear that cSDH is associated with worse long term functional and cognitive outcomes compared to matched controls. Though surgical techniques for treatment of cSDH are becoming more effective and safe, a persisting problem of fluctuating, stroke-like neurological deficits has re-emerged. Such deficits are not always directly related to hematoma mass effect and not always relieved with surgical decompression, but can result in prolonged hospital course, additional workup, and sometimes even additional invasive treatments. While the cause of such events is unknown, we recently documented for the first time that massive waves of spreading depolarization can occur in these patients and were closely linked to such neurologic deficits in some patients. In the current study, we plan to expand on these preliminary findings with rigorous, standardized application of post operative subdural electrocorticography monitoring, pioneered at our institution to detect SD. We also plan to build on our large retrospective analysis estimating the overall incidence of such deficits in cSDH patients by assessing multiple proposed risk factors for SD. In addition, for the first time, we will assess the short- and long-term consequences of cSDH and SD with detailed functional, cognitive, and headache related outcome measurement. These assessments are based on several remarkable cases we have observed with time-locked neurologic deterioration associated with recurrent SD. This study qualifies as a mechanistic clinical trial in that we will be prospectively assigning patients to the intervention of SD monitoring and assessing outcomes related to the occurrence of SD. This constitutes the application of a novel measure of brain signaling and assessing biomarkers of these physiologic processes of SD. These studies will provide critically needed information on this novel mechanism for neurologic deficits and worse outcomes after cSDH evacuation. Upon successful completion, we would identify a targetable mechanism for poor outcomes that occur commonly in patients with cSDH. This overall strategy offers the opportunity to radically improve the care of patients with cSDH by focusing on clinical trials of pharmacologic therapies for neurologic deficits in patients with cSDH.
Comparison of Narcotrend and Cerebral Function Analysing Monitor in Intensive Care to Monitor Seizures...
Traumatic Brain InjurySubarachnoid Hemorrhage7 moreA study in the use of the Narcotrend depth of anaesthesia monitor to record a) seizures, and b) monitor a level of sedation referred to as 'burst suppression', in sedated patients in the adult and paediatric intensive care. Studies have shown that patients in coma on the intensive care unit may have subclinical in addition to clinical seizures. Subclinical seizures are seizures that do not show any outward signs and may go undetected. The current gold standard of recording seizures in the intensive care unit is by non-invasive, continuous monitoring of the electrical activity of the brain by electroencephalography (cEEG) using cerebral function analysing monitor (CFAM). This is recorded with simultaneous video recording and is performed by Clinical Neurophysiology departments. There has been a steady increase in demand for this service over recent years. Additionally, CFAM / cEEG is labour intensive and expensive. If trends continue, the proportion of hospitals offering CFAM / cEEG will continue to rise, creating increased demand for specialist staff, of which there are a finite number. Depth of anaesthesia monitors are used by anaesthetists to assess the level of anaesthesia in sedated patients using specialised, automated EEG analysis and are now recommended by NICE (DG6) to tailor anaesthetic dose to individual patients. This study aims to investigate the utility of the Narcotrend depth of anaesthesia monitor to monitor for seizures and burst suppression on the adult and paediatric intensive care unit. These monitors are cheaper and more widely available with the scope to be used at every bed space requiring neuro observation on the intensive care unit. The study aims to recruit all patients who are referred for CFAM / cEEG monitoring at Nottingham University Hospitals (NUH) Trust over a 12 month period. These patients will undergo simultaneous recording using CFAM / cEEG and depth of anaesthesia monitoring.
