Minimally Invasive Surgical Treatment of Acute Epidural Hematoma: Case Series

Figure 5

(a)–(d) Head CT images showing a huge acute epidural hematoma with cerebral hernia at the right temporal-parietal region prior to and after surgery. (a) Head CT scan image prior to surgery; hematoma volume was approximately 145 mL and midline shift 13 mm. (b) Hematoma volume with rapid minimally invasive aspiration under local anesthesia was approximately 40 mL; drainage tube was placed. (c) Skull bone flap was opened during surgery; an arrow indicates a partly aspirated hematoma in the hematoma center. (d) Head CT scan reexamined the day after surgery; drainage of hematoma was almost complete, brain tissues were expanded again, midline shift was improved, dilated pupil is recovered and light reflection was recovered.
