Insights
Pneumocephalus, or air in the skull, commonly occurs after chronic subdural hematoma surgery. This study found that post-surgical pneumocephalus does not impact patient outcomes or recurrence rates, as it typically resolves on its own.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Pneumocephalus is a frequent complication following burr-hole drainage for chronic subdural hematoma (CSDH).
- The clinical significance and impact of post-surgical pneumocephalus on patient prognosis have not been extensively investigated.
Purpose of the Study:
- To investigate the relationship between postoperative pneumocephalus volume and clinical outcomes in patients undergoing CSDH drainage.
- To assess the correlation of pneumocephalus with Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) scores, and CSDH recurrence.
Main Methods:
- Retrospective analysis of 140 patients with CSDH treated with single burr-hole drainage.
- Calculation of pre- and postoperative hematoma volumes and postoperative pneumocephalus volume.
- Statistical analysis of the relationship between pneumocephalus volume and GCS/GOS scores, and recurrence rates.
Main Results:
- Preoperative hematoma volume and patient age positively correlated with 1-day postoperative pneumocephalus volume.
- No significant correlation found between postoperative pneumocephalus volume and GCS/GOS scores.
- No difference in GCS/GOS scores or CSDH recurrence rates between patients with and without pneumocephalus.
Conclusions:
- Pneumocephalus, within a certain range, does not adversely affect the prognosis of CSDH patients after surgery.
- The self-absorbing nature of pneumocephalus suggests no specific intervention is typically required.
Abstract:
Background: Pneumocephalus is a common finding after burr-hole drainage of chronic subdural hematoma (CSDH). Its effects have not been specifically studied.Methods: A retrospective analysis was performed in 140 patients with CSDH with single burr-hole drainage. The pre- and postoperative volumes of intracranial hematoma and the postoperative volume of pneumocephalus were calculated and analyzed with their relationships with Glasgow Coma Scale (GCS) and Glasgow Outcome Scale (GOS) scores.Results: The preoperative hematoma volume and the patient ages are positively correlated with the 1-day postoperative pneumocephalus volume (p < 0.001, p < 0.01). There is no correlation between postoperative pneumocephalus volume and GCS/GOS scores (p > 0.05) and there is no difference of GCS/GOS scores or CSDH recurrence rate between patients with and without pneumocephalus (p > 0.05). The age and the volume of 1-day postoperative pneumocephalus are positively correlated with the absorbing rate of pneumocephalus (p < 0.01, p < 0.001).Conclusions: The pneumocephalus at a certain range has no effect on the prognosis of patients with CSDH and requires no specific intervention due to its self-absorbing capacity in the normal progress after surgery.HighlightsNo correlation between postoperative pneumocephalus volume and GCS/GOS scores.No difference of GCS/GOS or recurrence between patients with pneumocephalus or not.Pneumocephalus at certain range has no effect on the prognosis of patients.
