چکیده

PURPOSE To determine whether certain patients with epidural hematomas would benefit from conservative treatment and to assess the neuroradiologist's role in decision-making. METHODS We reviewed the CT scan findings, clinical presentation and outcome of 48 consecutive patients with epidural hematoma managed at our institution within the past 5 years. In 18 patients, initial management was nonsurgical, and only one of these went on to require surgery due to clinical deterioration and evidence of enlargement of hematoma on CT. The remainder of these 18 did well without surgery. OBSERVATIONS AND CONCLUSIONS Clinical indicators of neurologic dysfunction (decrease in Glasgow coma scale score, pupillary dilatation, and hemiparesis) in the presence of even small epidural hematomas usually dictates the need for surgical management. The role of the neuroradiologist is most important when the patient presents in a good clinical state, when identification of both favorable and unfavorable prognostic factors on Ct is essential. The initial diameter of nonsurgically managed epidural hematomas generally must be small (mean, 1.26 cm in our series, all under 1.5 cm), and midline shift should be minimal (mean, 1.8 mm in our series). The identification of lucent areas within the epidural hematoma (suggesting active bleeding), or CT evidence of uncal herniation, can be ominous and the neurosurgeon must be alerted to their presence. Even in the presence of a favorable clinical status, presence of a larger epidural hematoma with significant mass effect or central lucent areas should alert the neuroradiologist and neurosurgeon to the strong possibility of sudden neurologic deterioration, and indicate the probable need for surgical management.

Role of Tranexamic Acid in Treatment of Patients with Epidural Hematoma

Introduction: Traumatic brain injury is considered as the major cause of mortality and hospitalization of about ten million people across the globe. Most of these patients are young and active people suffering disabilities. Tranexamic acid therapy is commonly used to reduce blood loss and need for blood transfusions in surgical cases. This study aimed at investigating the effect of tr...

Acute Epidural Hematoma after Ventriculoperitoneal Shunt Insertion: a Case Report

Background & Importance: Acute epidural hematoma is a very rare complication of ventriculoperitoneal shunt insertion. The insertion of a ventriculoperitoneal shunt can cause sudden decompression of the brain, subsequent to which epidural hematoma occurs due to CSF drainage. To our knowledge, there are only a few cases of acute epidural hematoma in the literature which required acute e...

Extradural hematomas: surgical and nonsurgical treatment.

We read with interest the paper, "Nonoperative Management of Acute Epidural Hematoma Diagnosed by CT: The Neuroradiologist's Role" (1). The paper focuses on the contribution of neuroradiology in providing information to neurosurgeons about which extracerebral hematomas can be treated nonsurgically. The conclusions are that favorable prognostic features can be identified (small lesion volume, mi...

Follow-up of conservatively managed epidural hematomas: implications for timing of repeat CT.

BACKGROUND AND PURPOSE Small asymptomatic epidural hematomas (EDHs) are frequently managed nonoperatively with good neurologic outcome. Our goals were to determine the frequency and timing of enlargement of acute traumatic EDHs that are not immediately surgically evacuated as well as to identify factors associated with rehemorrhage. METHODS Of 252 consecutive patients with acute traumatic EDH...
