Filter by:This is a prospective randomised-controlled multi-centre trial based in Hong Kong to determine whether temporary subdural drain placement after burr hole evacuation of a chronic subdural haematoma can reduce the risk of recurrence. Consecutive patients, 60 years old or above, diagnosed to have symptomatic chronic subdural haematoma and indicated for burr hole operative drainage will be randomly allocated into one of two groups: (1) for intra-operative subdural drain placement (intervention group) or (2) not for drain placement (control group). Using web-based software block randomisation with an allocation ratio of 1:1 will be conducted. Instructions to use or not to use a drain will be contained in a sealed envelopes labelled with sequential study numbers. Intra-operatively, if the surgeon-in-charge judges that after burr hole evacuation of the haematoma the patient's condition is unsafe for drain placement, the subject will be excluded from the study. Otherwise, randomisation will be performed at this juncture by the opening of the sealed envelop. The procedure involves placing a prefabricated silicon drain into the subdural space according to a standard protocol and will be removed on the second post-operative day at the bedside. Subjects in whom the operating surgeon judges that drain placement is unsafe will be excluded from the study. Drainage is undertaken passively by hanging the collection bag at the bedside in a dependent position. In addition to general demographic, clinical and radiological presentation data, potential risk factors for recurrence will be documented. Serial computed tomography brain scans will be arranged (before discharge, at four weeks and six months) and the occurence of significant subdural haematoma recurrence requiring repeat operative drainage at six months will be recorded. Other outcome measures to be determined at regular time intervals for a total follow-up period of six months (upon discharge, at four weeks and six months) include: functional performance in terms of the extended Glasgow Outcome Scale and modified Rankin Scale, added neurological deficit, death and other surgery-related complications. All outcomes will be documented by the trial investigators or by the responsible clinician. The data obtained will be analysed according to the principle of intention to treat. Hypothesis: compared to burr-hole evacuation of chronic subdural haematoma alone (control), the additional placement of a subdural drain after evacuation (intervention) will reduce the risk of recurrence requiring repeat surgery.
The purpose of this study is to determine the best strategy to manage novel oral anti-coagulants (NOACs) at the time of pacemaker or defibrillator surgery. The Investigators hypothesize that performing device surgery without interruption of the novel oral anti-coagulant will result in a reduced rate of clinically significant hematoma.
Chronic subdural hematoma (CSH) is one of the most common bleedings of the head. These hematomas develop after minor head trauma and increase in size over weeks. Patients usually present with headaches, gait disturbances, language problems or confusion. The state of the art treatment of a symptomatic chronic subdural hematoma is to remove the hematoma by burr hole trepanation. The optimal follow-up for operated patients remains controversial. Due to the known high rate of a second hematoma at the same place (usually within weeks), one strategy is to perform serial computer tomography scans in order to identify recurrent hematomas early. The radiologic evidence of a second hematoma often leads to reoperation, even if the patient has no, or just slight symptoms. Another strategy after surgical hematoma evacuation is to closely follow the patient with neurological examinations and perform neuroimaging only in case of new symptoms. Advocators of this strategy argue that a follow-up with routine CT scans may be harmful due to additional and maybe unnecessary surgeries and hospital days in a patient population marked by advanced age and fragility. The aim of the current study is to evaluate the role of computer tomography scanning in the postoperative follow-up after removal of a chronic subdural hematoma. Participants of this study will be allocated by chance to one of two study groups: Patients allocated to group A will receive a computer tomography scan on day 2 and again on day 30 after surgery in addition to a clinical examination. Patients allocated to group B will be examined clinically on day 2 and day 30 without computer tomography. All patients will undergo a final clinical examination after 6 months. The study will recruit 400 patients.
Cerebral edema is seen heterogenous group of neurological disease states that mainly fall under the categories of metabolic, infectious, neoplasia, cerebrovascular, and traumatic brain injury disease states. Regardless of the driving force, cerebral edema is defined as the accumulation of fluid in the brain's intracellular and extracellular spaces. This occurs secondary to alterations in the complex interplay between four distinct fluid compartments within the cranium. In any human cranium; fluid is contained in the blood, the cerebrospinal fluid, interstitial fluid of the brain parenchyma, and the intracellular fluid of the neurons and glia. Fluid movement occurs normally between these compartments and depends on specific concentrations of solutes (such as sodium) and water. In brain-injured states, the normal regulation of this process is disturbed and cerebral edema can develop. Cerebral edema leads to increased intracranial pressure and mortality secondary to brain tissue compression, given the confines of the fixed-volume cranium. Additionally, secondary neuronal dysfunction or death can occur at the cellular level secondary to the disruption of ion gradients that control metabolism and function. While studies utilizing bolus dosing of hyperosmolar therapy to target signs or symptoms of increased intracranial pressure secondary to cerebral edema are numerous, there is a paucity of studies relating to continuous infusion of hyperosmolar therapy for targeted sustained hypernatremia for the prevention and treatment of cerebral edema. The investigators hypothesize that induced, sustained hypernatremia following traumatic brain injury will decrease the rate of cerebral edema formation and improve patient outcomes.
This trial is conducted in the United States of America (USA). The aim of this trial is to evaluate the safety and preliminary efficacy of activated recombinant human factor VII (NovoSeven®) for preventing early hematoma growth in acute Intracerebral Hemorrhage (ICH).
Hysterectomy is one of the common operations in gynecology. With population aging in modern society, the incidence of these surgeries is expected to increase even more. One of the major complications of pelvic surgery is symptomatic pelvic hematoma, which can present with pain, fever, and foul smelling discharge. The incidence of pelvic hematoma is 40%, and varies according to the type of hysterectomy and the diagnostic procedure. Those hematoma increase the risk for infection. Diagnosis usually is not a clinical one unless symptoms occur, and then the diagnosis is made by CT or ultrasound. Number of interventions are mentioned in the literature to try and decrease post operative complications and infections, none have suggested effective enough. This is a prospective study which objective is to characterize the incidence of pelvic hematoma following hysterectomy using ultrasound. The investigators will also try to identify preoperative, intraoperative and postoperative risk factors for infection of this hematomas. This identification might decrease the incidence of postoperative hematoma and infection.
Anti-aggregation therapy, including treatment with low-dose aspirin (LDA) is an established risk factor for intracranial hemorrhage, including chronic subdural hematoma (CSDH); however evidence guiding the decision to continue or discontinue LDA in patients who have sustained mild head trauma with no sign of injury on CT is lacking. The investigators aim to assess whether continued aspirin treatment increases the risk of CSDH in mild head trauma patients 50 years and older who present with negative head CT. The investigators further aim to use the initial findings to refine the study design, with the goal of performing a larger, multi-institutional study in the future. Over a 12-month period, approximately 100 patients ≥50 years of age on LDA prophylaxis presenting to Hadassah's Emergency Department after sustaining mild head injury, will be examined by the neurosurgeon on call. Those who have no sign of intracranial hemorrhage at clinical or CT examination, and who meet inclusion / exclusion criteria, will be invited to participate in a randomized study. Informed consent will be obtained. Patients will be remotely randomized for continuation or cessation of LDA treatment. Follow-up CT and clinical examination will be performed 3-5 weeks after trauma. The two-proportions test will be used to assess whether there is a statistically significant difference in the rate of CSDH in patients randomized to cessation of LDA therapy and those randomized to continuation of LDA. Relationships between the explanatory the dependent variables will be explored with classical parametric and nonparametric statistical methods, including multivariate analysis, logistic regression, the two proportions test, and the independence test. Several measures of association/correlation between pairs of variables will be analyzed as well. The investigators hypothesize that continuation of LDA will not be associated with increased risk for chronic subdural hematoma, and that cessation of treatment will not be associated with a decrease in chronic subdural hematoma. The investigators further hypothesize that cessation of LDA for this period will not be associated with increased risk for clinically significant cerebrovascular, cardiovascular, thrombotic, of embolic event.
This is a multicenter, simple blind, masking of outcomes assessors, parallel, randomised clinical trial in patient with muscle rupture and with hematoma production. The main hypothesis is that infiltration in the area of muscle injury in autologous platelet-rich plasma (PRP)improves muscle regeneration and repair by shortening the time to complete recovery. The main objective is to evaluate the PRP for healing muscular lesions 'tennis leg' type or distal rectus femoral. The secondary objectives are: to evaluate the risk of lesion recurrence; to evaluate the quality of lesion recovery process and evaluate intervention's safety. Experimental treatment will be the administration of PRP autologous (4-8 cc in a unique dose) by muscular infiltration en the empty space generated after the hematoma evacuation. Control treatment will be hematoma evacuation. Both treatment groups will use compressive bandage and they will recommend rest, extremity elevation, local ice and lately physiotherapy. Size sample: 76 patients (38 in each group)
The primary objective of this exploratory cohort study is to describe levels of platelet reactivity in patients on a thienopyridine awaiting coronary artery bypass grafting (CABG).
The chronic subdural hematoma is a common disease in the population over 60 years. For example, in patients over 70 years, it occurs every year 7 new cases per 100,000 people. A chronic subdural hematoma is an accumulation of blood in the intracranial space between brain membrane (dura mater) and the brain. The origin of blood in this area follows a minor brain injury, which causes the rupture of small vessels in the area. During its evolution, the volume of the hematoma increases. After a few weeks, the amount of fluid build-up can compress the brain. That's when clinical symptoms occur: persistent headaches, neurological deficits, seizures, impaired consciousness, cognitive functions (memory loss, impaired intellectual function, or hallucinations, etc.). The compression of the brain may cause impairment of consciousness resulting in more severe cases coma and death. At this stage, a neurosurgical intervention is necessary. Recurrences are numerous (15 to 25% recurrence over six months after neurosurgery). That is why in France, about 20% of medical teams administer a postoperative treatment with corticosteroids to reduce the risk of recurrence. Until now, the potential benefit of this treatment has not yet been confirmed by a clinical study. So the purpose of this research.
