Anticoagulation Therapy Timing in Atrial Fibrillation After Acute and Chronic Subdural Hematoma...

Subdural HematomaAtrial Fibrillation

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.

Management of CSDH With or Without EMMA- a Randomized Control Trial

Chronic Subdural Hematoma

EMMA-Can is an open-label randomized control trial comparing the recurrence risk in patients with chronic subdural hematoma (CSDH) undergoing standard of care treatment (surgical drainage and/or medical management) with or without embolization of the middle meningeal (EMMA).

The Role of Meningeal Lymphatic Vessels in the Absorption of Chronic Subdural Hematoma and Its Injury...

Chronic subdural hematoma (CSDH) is a very common hemorrhagic disease of the nervous system, accounting for about 10% of hemorrhagic strokes. The incidence rate of elderly people over 65 years old is 58.1/100,000, and the incidence rate is increasing year by year, and it may reach 121/100,000 by 2030. At present, the specific pathogenesis of CSDH is still unclear. Although it has been clinically confirmed that a part of CSDH can be absorbed by itself, and some drugs such as atorvastatin can speed up the process, surgical treatments such as cranial craniotomy or cranial drilling hematoma removal are still the only options for patients with CSDH. Lymphatic circulation spreads throughout most tissues of the human body, assists in removing metabolic wastes in the interstitium, maintains body fluid homeostasis, and plays a role in immune response and immune surveillance. For a long time, the central nervous system has been considered as an immune-privileged organ, that is, the central nervous system does not have the presence of the lymphatic system. Until 2015, Louveau et al. used immunofluorescence staining and other techniques to find functional lymphatic ducts adjacent to the dural venous sinuses in the mouse brain when looking for the channels for T cells to enter and leave the meninges, confirming the first intracranial meningeal lymphatic vessels. (mLVs), and found that mLVs express the classic markers of lymphatic endothelial cells (LECs), namely VEGFR3, prostate homeobox 1 (PROX 1), podoplanin, lymphatic endothelial markers transparent Ronidase receptor-1 (LYVE-1), etc. Relevant studies have confirmed that meningeal lymphatic vessels can drain interstitial fluid (ISF), macromolecular substances and immune cells out of the skull, providing a new drainage pathway for the excretion of metabolic waste from the central nervous system. Subsequent studies have confirmed that mLV is involved in the pathophysiological process of a series of neurological diseases such as Alzheimer's disease (AD), traumatic brain injury (TBI), and subarachnoid hemorrhage (SAH). This phenomenon suggests that mLVs play an important role in central nervous system diseases.

Chronic Subdural Hematoma

Chronic subdural hematomas (CSH) are collections of blood in the subdural space. CSH are becoming the most common cranial neurosurgical condition among adults, and a significant public health problem, due to an increasing use of anticoagulant and antiplatelet medication in an ageing population. Symptomatic CSH, or CSH with a significant mass effect, are treated surgically. However, recurrences are common (10 to 20%). Conservative management (medical) is used in patients who are asymptomatic or have minor symptoms. However, therapeutic failures, requiring surgical treatment, are common. The pathophysiology of CSH involves inflammation, angiogenesis, and clotting dysfunction. Self-perpetuation and rebleeding is thought to be caused by neo-membranes from the inflammatory remodeling of the dura-mater mainly fed by the distal branches of the middle meningeal artery (MMA). There are 13 ongoing registered RCTs in CSH, with the most common covering application of steroids, surgical techniques and tranexamic acid. Further to this, there are trials running on other pharmacological agents, and peri-operative management. Some industrial or academic trials are or will enroll in France in the next year in France. But to our best knowledge, none of these trials will the eventual benefits of the MMA embolization in both cases of medical and/or surgical management, and none will focus on the use of cyanoacrylates (CYA) for this purpose. Preliminary case series and nonrandomized retrospective studies have suggested that MMA embolization alone or as adjuvant therapy to surgery can decrease recurrences. The investigators hypothesize that in both conditions of conservative or surgical managements, endovascular embolization of patients with CSH significantly reduces the risk of recurrence of CSH. The investigators choose the CYA as liquid embolic agent because of the pain and cost of the use of Ethylen Vinyl alcohol copolymer (EVOH) agents and its simplicity to be used.

Targeting Spreading Depolarization After Chronic Subdural Hematoma Surgery (TASD)

Chronic Subdural Hematoma

Chronic Subdural Hematoma (cSDH) is an extremely common problem, particularly in the aging population, where fluid like collections compress the brain, frequently requiring surgical drainage. After drainage, 25-50% of patients experience post operative neurologic deficits such as weakness or confusion that are often not explained by problems such as seizure, stroke, or mass effect from the fluid and blood. Recent subdural recordings have demonstrated that some of these neurological deficits may be related to waves of spreading depolarization (SD), which cause temporary neurological dysfunction. Our overall objective is to examine the relationship between neurological deficits and SD and to assess feasibility of a pilot trial to determine if a strategy of NMDA-R antagonism can effectively reduce SD and improve clinical recovery.
