Active clinical trials for "Hematoma, Subdural, Chronic"

Some patients with chronic subdural hematomas and transient neurological symptoms do not respond to standard antiepileptic drugs. The investigators think that some of them could have cortical depression rather than epileptic discharges. After an intensive literature review, the investigators found out that some antiepileptic dugs (Lamotrigine, Topiramate) were found to be efficient to treat cortical depression in other conditions (migraine, subarachnoid hemorrhage). In contrast, some other drugs (Levetiracetam) were not proved to be efficient. Knowing that, the investigators want to compare the efficacy of Topiramate against Levetiracetam in two different groups, the NESIS group (based on a NESIS score of 4 or more - increased risk of cortical depression) versus a non-NESIS group (score of 3 or less - increased risk of epileptic discharges).

This prospective, double-blind, randomized, placebo-controlled study aims to evaluate the efficacy and safety of atorvastatin in patients with chronic subdural haematoma. The degree of disability or dependence in daily activities, as well as surgical intervention or recurrence, of the treatment and control groups will be compared.

This is a prospective, multi-center, open-label, randomized controlled study in which subjects can receive standard of care (SOC) alone or SOC and TRUFILL n-BCA MMA embolization for the treatment of chronic subdural hematomas (cSDH).

A prospective, multicenter, randomized controlled trial is designed to compare the recurrence rates and clinical outcomes in patients with chronic subdural hematoma using exhaustive drainage or fixed-time drainage after one-burr hole craniostomy.

Chronic subdural hematoma (cSDH) is a common neurological affliction which affects mostly frail and elderly patients. Surgical evacuation by using burr hole craniostomy (BHC) is the most frequently used treatment but carries a recurrence rate varying between 10-30% in the literature. Especially in this frail population re-operation is undesirable. Embolization of the middle meningeal artery is an adjuvant treatment which has been reported in multiple case reports and larger case series, showing a beneficial effect on recurrence rate, reducing it to <5%, without complications. Objectives: Primary: To evaluate whether additional embolization of the middle meningeal artery after surgery for cSDH reduces the recurrent surgery rate. Secondary: to evaluate whether the use of middle meningeal artery embolization after surgical treatment in symptomatic cSDH patients increases quality of life (SF-36 and the EQ-5D-5L), performance in activities of daily living (AMC Linear Disability Score), functional outcome (mRS), cognitive functioning (MOCA) and reduces mortality, occurrence of complications, recurrence rate, size and volume of the hematoma, neurological impairment (mNIHSS, Markwalder score) and the use of care and health-related costs (iMCQ and iPCQ). Study design: Multicenter, randomized controlled open-label superiority trial. Study population: Patients diagnosed with a cSDH who require surgery. Intervention: The intervention group will receive embolization in addition to standard surgical treatment. The control group will receive surgery only. Main study endpoint: The number of patients who require reoperation within 24 weeks after the intervention. Symptomatic cSDH patients will undergo peri-operative embolization of the middle meningeal artery until 72 hours after surgical treatment. Complications are monitored during hospital admission and follow-up. Radiological and clinical follow-up is at eight, 16 and 24 weeks post-intervention with a CT-scan of the head and assessment of mRS, MOCA, mNIHSS, Markwalder score, SF-36, EQ-5D-5L, ALDS, iMCQ and iPCQ. Standard care after surgery entails outpatient follow-up with on average two CT-scans, indicated by clinical signs and symptoms.

The SWEMMA trial is an open, national, multi-center, prospective, randomized (1:1), superiority trial designed to assess impact on reoperation rates for chronic subdural hematoma with a head-to-head comparison of embolization of the middle meningeal artery (intervention) with standard neurosurgical hematoma evacuation (control).

A prospective, multicenter, randomized controlled trial is designed to evaluate the safety and efficacy of nerve block anesthesia combined with sedative anesthesia versus general anesthesia during burr hole craniostomy with drainage for chronic subdural hematoma.

To determine the utility of tissue plasminogen activator (tPA) in the clearance of chronic subdural hematomas (CSDH). Intra-catheter tPA will be administered during surgical procedure and allowed to break down blood clot to assist with removal/drainage during twist drill craniostomy procedure.

Chronic subdural hematomas (cSDH) are one form of bleeding in the head. They are one of the most common diseases encountered by neurosurgeons across the country. The cSDH can push on the brain and produce symptoms that include seizures, weakness, loss of sensation, and confusion. Many of these cSDH produce repetitive bleeding. Treatment has largely consisted of surgical drainage of hematoma (also known as a blood clot) through either a small hole in the skull or open surgery. However, it is common for the cSDH to reappear despite these procedures. A recent study has shown a treatment failure rate of 27% and a need for additional surgery at 19%. A new approach to treatment of cSDH blocks the blood supply to the tissue that produces the repeated bleeding. Catheters are used to gain access to the middle meningeal artery (MMA), an artery that supplies the coverings of the brain. The artery is blocked using small particles or glue in a process called embolization. A recent pilot study of 72 patients who underwent MMA embolization showed a much lower rate of repeated bleeding. Based on these results, it is thought that this procedure holds promise in reducing the number of cSDH that require one or more operations. The goal of this study is to systematically examine if blocking the blood supply to the tissue responsible for repeated bleeding helps the cSDH resolve and improves patient outcomes.

Subdural hematoma (SDH) is a common disorder that typically results from head trauma and has increased in prevalence in recent decades. Acute subdural hematomas (aSDH) are found in up to one-third of patients with severe traumatic brain injury and are associated with an unfavorable outcome in the majority of cases. Chronic subdural hematomas (cSDH) commonly occur in the elderly population which has highest risk for developing cSDH with or without minor head injuries. The combination of the aging population, higher incidence of disease in progressively older patients, and high morbidity and mortality renders SDH a growing problem within Canada with significant health-systems burden. SDH commonly recurs even after successful surgical drainage. Atrial fibrillation (AF) is one of the most common medical comorbidities in patients with cSDH, especially in the elderly, with an expected doubling of its prevalence by the year 2030. Patients with AF are at recognized risk for stroke, so anticoagulation is indicated for almost all patients. Anticoagulation is held prior to SDH drainage to minimize the risk of intraoperative and early postoperative bleeding. After surgery, the risk of SDH recurrence must be balanced against the risk of thromboembolic events such as stroke when deciding the timing of resuming anticoagulation. Currently the decision on when to restart anticoagulation after SDH is made by clinicians on an individual patient basis without any high-quality evidence to guide this decision. The two most common approaches are: 1) early resumption of anticoagulation after 30 days of diagnosis or surgery; and 2) delayed resumption of anticoagulation after 90 days of diagnosis or surgery. However, which of these approaches leads to the best functional outcomes for patients is unclear. Our pilot RCT will test the feasibility of comparing these 2 approaches in a larger multicenter RCT.
