A subdural hematoma is a type of bleeding near the brain that occurs when there is a tear in a blood vessel, causing blood to leak out and collect between the dura mater and the arachnoid mater. This condition is often the result of a head injury, with symptoms such as headaches, nausea, vomiting, and slurred speech. Given the severity of this condition, it is crucial to seek immediate medical attention. Treatment options include surgery, medication, and middle meningeal artery (MMA) embolization, with hospital stays varying depending on the chosen treatment and the patient's health status. The length of hospitalization for subdural hematoma patients is influenced by factors such as the severity of the hematoma, the chosen treatment method, and the patient's recovery progress.

Surgery for subdural hematoma
A subdural hematoma is a buildup of blood on the surface of the brain. It occurs when blood collects between the outer surface of the brain and the dura mater (the brain’s protective covering). The blood builds up in a space between the protective layers that surround the brain. The dura is the outermost covering of the three layers of the meninges, which cover and protect the brain.
However, in recent years, a minimally invasive procedure called endovascular embolization has emerged as a safe and effective alternative. During this procedure, a tiny catheter is inserted through a blood vessel in the leg and guided to the bleeding site in the brain. Microscopic particles, called embospheres, are then delivered to stop the bleeding at its source. This technique has long been used to treat brain aneurysms and other vascular conditions, and its application to subdural hematomas is showing promising results. Many patients who would have been considered high-risk for open surgery may now be good candidates for this minimally invasive approach.
The decision to perform surgery for a subdural hematoma depends on several factors. If the hematoma is small and the patient is stable, healthcare providers may opt for close monitoring in an Intensive Care Unit (ICU) instead of immediate surgery. This monitoring may include intracranial pressure sensors, medications, and CT scans to watch the hematoma. Surgery may become necessary if the hematoma grows or causes symptoms.
The timing of surgery is also important, and while there is an adage that "the sooner the surgery is done, the better," this may not always be the case. The decision about when to operate depends on the individual case and the patient's neurological and medical condition.
Retreatment rates after surgery for subdural hematoma are generally low, and when they do occur, they usually happen within 3 months of the initial treatment. This suggests that routine follow-up beyond 3 months may not be necessary for most patients.

ICU admission
A subdural hematoma is a buildup of blood on the surface of the brain, which can be life-threatening. It occurs when blood seeps between the dura and the arachnoid layers, collecting inside the brain's tough outer lining. This is usually caused by a head injury, which can be mild, and is often the result of a car crash, fall, or violent attack. Younger men are most likely to experience these injuries, but older adults are at higher risk due to the increased likelihood of tearing veins.
In the case of a small hematoma, surgery may not be required immediately, and patients will likely be admitted to an Intensive Care Unit (ICU) for close monitoring. In the ICU, patients may require a sensor inside the head to measure intracranial pressure, medicines to control symptoms, and CT scans to monitor the hematoma.
The average length of stay in the ICU for patients with subdural hematoma was found to be 5.7 days, with an average total hospital stay of 9.4 days, in a study of 87 patients between 2011 and 2014. This study also found that patients with small traumatic subdural hematomas spent less time in the ICU and demonstrated neurologic and medical stability.
However, another study found that the presence of warfarin and a subdural hematoma of at least 1 cm were independently statistically significant factors associated with admission to the ICU. Additionally, larger subdural hematomas have been associated with worse outcomes, and patients with hematomas of at least 10 cm^3 were found to be at risk of neurological decline and worse clinical outcomes.
Therefore, while the length of ICU stay can vary depending on the size of the hematoma and other factors, patients with subdural hematomas typically require intensive care monitoring and close observation to ensure their safety and stability.

Recovery time
Subdural hematoma is a type of intracranial hemorrhage that occurs beneath the dura, resulting in a collection of blood over the surface of the brain. It is a common neurosurgical disorder that often requires surgical intervention. The two widely used surgical techniques to treat subdural hematomas are craniotomy and burr holes. During a craniotomy, a section of the skull is temporarily removed to access and remove the hematoma. In the case of burr holes, a small hole is drilled into the skull, and a tube is inserted to drain the hematoma.
In some cases, very small subdural hematomas may be monitored first to see if they heal without surgery. If surgery is not required, patients may still need to stay in an Intensive Care Unit (ICU) for close monitoring. The average length of stay in the ICU for patients with subdural hematoma is around 5.7 days, while the average length of the overall hospital stay is around 9.4 days.
If surgery is performed, the recovery time can vary. Some patients may be well enough to leave the hospital after a few days if the surgery goes well and there are no complications. However, if complications develop, it may take several weeks before the patient can be discharged. In some cases, the hematoma may recur during the days or weeks after surgery, requiring further surgery to drain it again.
Postoperative complications can include seizures, pneumonia, empyema, infections, acute subdural collection formation, intraparenchymal hematoma, and tension pneumocephalus. These complications can impact the recovery time, and further treatment may be needed to help patients gradually return to their normal activities.
It is important to note that the recovery time for subdural hematoma is highly variable and depends on various factors, including the patient's age, the severity of the hematoma, and the presence of other medical conditions.

Factors affecting hospital stay duration
The duration of a hospital stay for subdural hematoma varies depending on several factors. Firstly, the age of the patient plays a role. Older adults are at a higher risk of developing subdural hematomas due to brain atrophy, which increases the likelihood of blood vessel tears. Additionally, older patients may experience longer hospital stays due to concurrent medical conditions and increased sensitivity to anesthesia.
The severity of the hematoma also affects the length of hospitalization. Acute subdural hematomas are the most dangerous type, requiring immediate treatment to prevent loss of consciousness, paralysis, or death. Patients with larger hematomas tend to experience worse outcomes and longer hospital stays. In some cases, patients with small hematomas may not require intensive care unit (ICU) admission and can be monitored in a hospital unit with a lower level of care.
The treatment method chosen is another factor influencing hospital stay duration. Subdural hematomas are often treated surgically, with procedures such as craniotomy or burr hole drainage. The type of surgery and the patient's response to it can impact the length of their hospitalization. In some cases, patients may require prolonged ICU stays for intensive monitoring and management of symptoms.
Underlying health conditions and medications can also play a role in hospital stay duration. Patients taking blood thinners, such as warfarin, may experience increased bleeding and require longer hospitalization. Additionally, patients with comorbidities or neurological decline may have extended hospital stays to manage their overall health and ensure stability.
Lastly, the presence of complications following surgery or drainage procedures can prolong a patient's hospital stay. Complications such as postoperative seizures, subdural empyema, brain abscess, or meningitis have been reported in a small percentage of patients. These complications often require additional treatment and monitoring, leading to a longer duration of hospitalization.

Complications and risks
A subdural haematoma is a collection of blood between the covering of the brain (dura) and the surface of the brain. It is a medical emergency and often requires emergency surgery to reduce pressure within the brain. The risks and complications associated with subdural haematoma include the following:
Risks
Subdural haematoma is most commonly caused by a head injury, which can be from a car crash, fall, or violent attack. In older adults, the veins are often already stretched due to brain shrinkage (atrophy), making them more susceptible to tearing and bleeding. Certain medications, such as blood thinners like warfarin or aspirin, can also increase the risk of subdural haematoma. In infants and young children, it may be a sign of child abuse, specifically shaken baby syndrome.
Complications
Subdural haematoma can lead to various complications, including:
- Brain injury: The bleeding can fill the brain area rapidly, compressing and damaging brain tissue.
- Death: Acute subdural haematomas have high rates of death.
- Long-lasting problems: Many individuals experience long-term issues such as changes in mood, concentration or memory problems, seizures, speech problems, and weakness in the limbs.
- Recurrence: There is a risk of the haematoma returning after treatment, requiring additional surgery or rehabilitation.
- Neurological decline: Larger haematomas are associated with worse outcomes, including neurological decline and poor clinical outcomes.
- Herniation: A large bleed can increase the distance between the bridging veins, leading to extensive bleeding around the brain and herniation of cerebral structures.
The length of hospital stay for patients with subdural haematoma varies depending on the severity of the condition and the effectiveness of treatment. On average, patients with subdural haematoma spend 9.4 days in the hospital, with 5.7 days in the Intensive Care Unit (ICU).

Frequently asked questions
The length of a hospital stay for subdural hematoma varies depending on factors such as age, severity, and treatment method. On average, patients with subdural hematoma spend 9.4 days in the hospital, with 5.7 days in the ICU.
Several factors can influence the length of a hospital stay, including age, severity of the hematoma, and the presence of other medical conditions. Older patients tend to have longer hospital stays, and larger hematomas are associated with worse outcomes and longer recovery times.
Yes, the treatment method can also impact the length of the hospital stay. Surgical intervention, such as craniotomy or burr hole drainage, may result in a shorter hospital stay compared to conservative management or monitoring. However, there are also risks associated with surgery, and complications may arise that extend the hospital stay.
Yes, certain factors can help determine the length of stay in the ICU. These include the patient's Glasgow Coma Scale (GCS) score, the presence of comorbidities, and the use of certain medications such as antiplatelet drugs. A higher GCS score and a lower number of comorbidities are associated with a shorter stay in the ICU.
The decision to admit a patient with subdural hematoma to the ICU varies depending on the institution and the patient's condition. Some institutions require all patients with subdural hematoma to be admitted to the ICU, regardless of the size of the hematoma. However, there are studies that suggest patients with small traumatic subdural hematomas may not require intensive monitoring and can be managed in a hospital unit with a lower level of care.
