Mgt of Chronic Subdural Hematoma Using Dexamethasone

Chronic Subdural Hematoma

Chronic subdural hematoma (cSDH) is a collection of blood and its breakdown products in the subdural compartment. It is a condition frequently seen in any neurosurgical practice. cSDH is believed to arise from tearing of bridging veins as a result of trauma, which may be minor and unapparent to the patient. Management of cSDH is widely varied. A wait-and-see or wait-and-rescan approach may be acceptable in asymptomatic patients with a relatively small hematoma whilst cSDH with severe neurological deficits or decreased level of consciousness may require surgical decompression by burr-hole craniostomy, twist drill craniostomy or craniotomy. Surgery is associated with serious morbidity and mortality of up to 17% and recurrence rates of 4%-33% requiring further treatment in some instances.The safety and efficacy of different neurosurgical procedures have been evaluated but there is a paucity of well-designed randomized controlled trials in the literature. Consequently, there is no consensus on the best treatment with respect to surgical technique, pre-operative and post-operative management and nonsurgical alternatives including the use of Corticosteroids, Tranexamic acid, Osmotic diuretics, Atorvastatin or Angiotensin converting enzyme (ACE) inhibitors. Corticosteroids may be a therapeutic option in the management of cSDH. There is very little data on the efficacy of corticosteroids in the treatment of cSDH and certainly no randomized trials. The purpose of the study is to prove dexamethasone can be just as efficacious as surgery in treating chronic subdural hematoma. The investigators also hope to show that those patients treated with dexamethasone suffer less complication compared to those who undergo surgery.

Chronic subdural hematoma (cSDH) is a collection of blood and its breakdown products in the subdural compartment. It is a condition frequently seen in any neurosurgical practice. cSDH is believed to arise from tearing of bridging veins as a result of trauma, which may be minor and unapparent to the patient. The one-year incidence rate is 1 to 8.2 per 100 000 in those 65 years or older. Advanced age is one of several risk factors and the incidence is expected to increase due to improved life expectancy. Other risk factors include brain atrophy, chronic alcoholism, intracranial hypotension, male gender and coagulopathy (including antiplatelet and antithrombotic therapy). Management of cSDH is widely varied. A wait-and-see or wait-and-rescan approach may be acceptable in asymptomatic patients with a relatively small hematoma whilst cSDH with severe neurological deficits or decreased level of consciousness may require surgical decompression by burr-hole craniostomy, twist drill craniostomy or craniotomy.
