To protect against blood clots, medications such as lovenox and heparin are given to any patient that is unable to get out of bed several times a day or simply have high risk factrors.
With a subdural hematoma, it's a bleed in the brain layers, so giving anything that increases the time for your body to form clots (blood thinners) could be harmful and increase bleeding.
An IVC filter is a minor proceedure to place a filter to catch any clots before they moved up the blood stream to the lungs or brain. Prevention of clot formation is a very high level goal of every patient in the hospital.

Subdural hematoma?
DefinitionA subdural hematoma is a collection of blood on the surface of the brain.Alternative NamesSubdural hemorrhageCauses, incidence, and risk factorsSubdural hematomas are usually the result of a serious head injury. When one occurs in this way, it is called an "acute" subdural hematoma. Acute subdural hematomas are among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury.Subdural hematomas can also occur after a very minor head injury, especially in the elderly. These may go unnoticed for many days to weeks, and are called "chronic" subdural hematomas. With any subdural hematoma, tiny veins between the surface of the brain and its outer covering (the dura) stretch and tear, allowing blood to collect. In the elderly, the veins are often already stretched because of brain atrophy (shrinkage) and are more easily injured.Some subdural hematomas occur without cause (spontaneously).The following increase your risk for a subdural hematoma:Anticoagulant medication (blood thinners, including aspirin)Long-term abuse of alcoholRecurrent fallsRepeated head injuryVery young or very old ageSymptomsConfused speechDifficulty with balance or walkingHeadacheLethargy or confusionLoss of consciousnessNausea and vomitingNumbnessSeizuresSlurred speechVisual disturbancesWeaknessIn infants:Bulging fontanelles (the "soft spots" of the baby's skull)Feeding difficultiesFocal seizuresGeneralized tonic-clonic seizureHigh-pitched cryIncreased head circumferenceIncreased sleepiness or lethargyIrritabilityPersistent vomitingSeparated sutures (the areas where growing skull bones join)Signs and testsAlways get medical help after a head injury. Older persons should receive medical care if they shows signs of memory problems or mental decline. An exam should include a complete neurologic exam.Your doctor may order a brain imaging study if you have any of the following symptoms:Confused speechDifficulty with balance or walkingHeadacheInability to speakLethargy or confusionLoss of consciousnessNausea and vomitingNumbnessRecent congitive decline in an elderly person, even without a history of brain injurySeizuresSlurred speechVisual disturbanceWeaknessA CT scan or MRI scan likely would be done to evaluate for the presence of a subdural hematoma.TreatmentA subdural hematoma is an emergency condition.Emergency surgery may be needed to reduce pressure within the brain. This may involve drilling a small hole in the skull, which allows blood to drain and relieves pressure on the brain. Large hematomas or solid blood clots may need to be removed through a procedure called a craniotomy, which creates a larger opening in the skull.Medicines used to treat a subdural hematoma depend on the type of subdural hematoma, the severity of symptoms, and how much brain damage has occurred. Diuretics and corticosteroids may be used to reduce swelling. Anticonvulsion medications, such as phenytoin, may be used to control or prevent seizures.Expectations (prognosis)The outlook following a subdural hematoma varies widely depending on the type and location of head injury, the size of the blood collection, and how quickly treatment is obtained.Acute subdural hematomas present the greatest challenge, with high rates of death and injury. Subacute and chronic subdural hematomas have better outcomes in most cases, with symptoms often going away after the blood collection is drained. A period of rehabilitation is sometimes needed to assist the person back to his or her usual level of functioning.There is a high frequency of seizures following a subdural hematoma, even after drainage, but these are usually well controlled with medication. Seizures may occur at the time the hematoma forms, or up to months or years afterward.ComplicationsBrain herniation (pressure on the brain severe enough to cause coma and death)Persistent symptoms such as memory loss, dizziness, headache, anxiety, and difficulty concentratingSeizuresTemporary or permanent weakness, numbness, difficulty speakingCalling your health care providerA subdural hematoma requires emergency medical attention. Call 911 or your local emergency number, or go immediately to an emergency room after a head injury.Spinal injuries often occur with head injuries, so try to keep the person's neck still if you must move him or her before help arrives.PreventionAlways use safety equipment at work and play to reduce your risk of a head injury. For example, use hard hats, bicycle or motorcycle helmets, and seat belts. Older individuals should be particularly careful to avoid falls.ReferencesHeegaard WG, Biros MH. Head. In: Marx JA, ed.
