To examine how the timing of onset and the length of the procedure affect recurrence, effectiveness, and postoperative recuperation in individuals diagnosed with chronic subdural hematoma (CSDH), highlighting the clinical significance of these factors.
Key Findings:
Patients with surgical duration exceeding 60 minutes had significantly higher postoperative GCS (p = 0.022) and KPS (p = 0.031) scores.
No significant differences in postoperative mRS (p = 0.149), ECOG scores (p = 0.077), recurrence rate (p = 0.200), or complications (p = 0.605) between groups based on surgical duration.
Surgical duration was weakly negatively correlated with postoperative mRS (ρ = −0.197, p = 0.030) and ECOG (ρ = −0.224, p = 0.013), and positively correlated with KPS (ρ = 0.258, p = 0.004) and GCS (ρ = 0.263, p = 0.004).
Interval from symptom onset to surgery was linked to longer hospital stays (p < 0.05).
Interpretation:
Longer surgical duration may be associated with better functional outcomes, but initial patient conditions and surgical approaches could confound these results, necessitating careful consideration.
Limitations:
Exploratory nature of the study with a limited sample size, which may affect the generalizability of the findings.
Lack of multivariate analysis to identify independent predictors, limiting the depth of the conclusions drawn.
Conclusion:
Operative time exceeding 60 minutes is linked to improved postoperative outcomes, but further large-scale studies are needed for validation to confirm these preliminary findings.
