Abstract:
Objective:To compare the efficacy of neuroendoscopy-assisted small bone window craniotomy and large bone flap craniotomy for acute subdural hematoma (ASDH) evacuation in elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 57 elderly patients with ASDH admitted to Chongqing University Fuling Hospital from November 2020 to November 2023, including 27 males and 30 females, aged 65-89 years [(75.0±7.0)years]. The preoperative Glasgow coma scale (GCS) ranged 8-15 points [11.0(11.0, 12.0)points]. Among them, 27 patients were treated with neuroendoscopy-assisted small bone window craniotomy to evacuate ASDH (small bone window group) and 30 received large bone flap craniotomy to evacuate ASDH (large bone flap group). The following parameters were compared between the two groups: surgical duration, intraoperative blood loss, and length of hospital stay; residual subdural hematoma volume before surgery and at 1 day after surgery; GCS before surgery, at 1 and 3 days after surgery; good rate of Glasgow outcome scale (GOS) at 7 days and 6 months after surgery; and postoperative complication rate.Results:All the patients were followed up for 6 months. The surgical duration, intraoperative blood loss, and length of hospital stay were 89.0(85.0, 96.0)minutes, 65.0(55.0, 85.0)ml, and 15.0(14.0, 16.0)days, respectively in the small bone window group, which were shorter or less than 135.0(127.5, 150.0)minutes, 332.0(308.0, 367.5)ml, and 18.5(16.0, 20.0)days in the large bone flap group ( P<0.01). There was no statistically significant difference in the residual subdural hematoma volume between the two groups before surgery and at 1 day after surgery ( P>0.05). No statistically significant difference was found in GCS scores between the two groups before surgery ( P>0.05), while the GCS scores in the small bone window group at 1 and 3 days after surgery [12.0(12.0, 13.0)points and 15.0(14.0, 15.0)points] were higher than 11.5(11.0, 12.0)points and 13.0(12.8, 14.0)points in the large bone flap group ( P<0.01). The good rate of GOS in the small bone window group at 7 days after surgery was 100% (27/27), higher than 77% (23/30) in the large bone flap group ( P<0.05), but no statistically significant difference was found in the good rate of GOS between the two groups at 6 months after surgery ( P>0.05). Two patients in the small bone window group had pulmonary infection after surgery, with a complication rate of 7% (2/27), while in the large bone flap group, four patients had pulmonary infection, two epidural hematoma, one intracranial infection, one delayed wound healing, one subcutaneous fluid accumulation, and one epilepsy after surgery, with a complication rate of 33% (10/30) ( P<0.05). Conclusion:Compared with the conventional large bone flap craniotomy, neuroendoscopy-assisted small bone window craniotomy can shorten the surgical duration and length of hospital stay, reduce the intraoperative bleeding volume, promote early functional recovery, improve prognosis, and reduce the complication rate in elderly patients with ASDH.
