From the Research

Surgical evacuation for a 7mm subdural hematoma (SDH) in the parietal region is typically not required unless there are significant neurological symptoms or deterioration. Most small SDHs of this size can be managed conservatively with close neurological monitoring, especially if the patient is neurologically intact or has minimal symptoms. The guidelines from 1 suggest that the decision for surgical evacuation should be based on the clinical presentation, patient's neurological status, comorbidities, and the characteristics of the hematoma rather than size alone. Some key points to consider in the management of SDH include:

  • Clinical presentation and neurological status: Patients with significant neurological symptoms or deterioration may require surgical intervention 2.
  • Size and location of the hematoma: While size is an important factor, it is not the only consideration. A hematoma of 7mm may not require surgical evacuation unless there are other concerning factors 3.
  • Patient comorbidities: Patients with certain comorbidities, such as coagulopathy or bleeding diathesis, may require more aggressive management 2.
  • Follow-up imaging: Regular imaging should be performed to monitor for expansion of the hematoma or increased mass effect 4. Conservative management includes:
  • Regular neurological assessments
  • Pain control with medications like acetaminophen or mild opioids if needed
  • Follow-up imaging to monitor for expansion of the hematoma
  • Advising the patient to rest, avoid activities that could lead to head trauma, and avoid blood thinners or antiplatelet medications unless absolutely necessary for other conditions. Surgical intervention would become necessary if the patient develops worsening symptoms such as severe headache, altered consciousness, focal neurological deficits, or if follow-up imaging shows significant expansion of the hematoma or increased mass effect 1. The most recent and highest quality study 1 provides a score to guide surgical decision-making, which can be useful in determining the best course of treatment for individual patients.
