Abstract
Objective
Acute subdural hematoma (ASDH) stands as a significant contributor to morbidity after severe traumatic brain injuries (TBI). The primary treatment approach for patients experiencing progressive neurological deficits or notable mass effects is the surgical removal of the hematoma, which can be achieved through craniotomy (CO) or decompressive craniectomy (DC). Nevertheless, the choice between these two procedures remains a subject of ongoing debate and controversy.
Materials and methods
We conducted a comprehensive literature review, utilizing prominent online databases and manually searching references related to craniotomy and craniectomy for subdural hematoma evacuation up to November 2023. Our analysis focused on outcome variables such as the presence of residual subdural hematoma, the need for revision procedures, and overall clinical outcomes.
Results
We included a total of 11 comparative studies in our analysis, encompassing 4269 patients, with 2979 undergoing craniotomy and 1290 undergoing craniectomy, meeting the inclusion criteria. Patients who underwent craniectomy displayed significantly lower scores on the Glasgow Coma Scale (GCS) during their initial presentation. Following surgery, the DC group exhibited a significantly reduced rate of residual subdural (P = 0.009). Additionally, the likelihood of a poor outcome during follow-up was lower in the CO group. Likewise, the mortality rate was lower in the CO group compared to the craniectomy group (OR 0.63, 95% CI 0.41–0.98, I2 = 84%, P = 0.04).
Conclusion
Our study found that CO was associated with more favorable outcomes in terms of mortality, reoperation rate, and functional outcome while DC was associated with less likelihood of residual subdural hematoma. Upon further investigation of patient characteristics who underwent into either of these interventions, it was very clear that patients in DC cohort have more serious and low pre-op characteristics than the CO group. Nonetheless, brain herniation and advanced age act as independent factor for predicting the outcome irrespective of the intervention.
