Intractable subdural effusion after decompressive craniectomy for traumatic brain injury: A case report

Figure 4 Computed tomography scan twentieth day after decompressive craniectomy. A-C: On the twentieth day after decompressive craniectomy, a computed tomography scan was performed again, showing a recurrence of subdural fluid accumulation on the right side (solid white arrow), with the midline shifting to the left again and significant compression on the right ventricle (dashed white arrow); D-F: After the second subdural puncture drainage surgery, a 7-day follow-up examination showed that the right-sided subdural effusion had basically disappeared (white solid arrows), the midline was basically centered, and the compression of the right lateral ventricle had improved (white dashed arrows).
