Background: The efficacy of endoscopic surgery for spontaneous intracerebral hemorrhages (ICH) has been previously reported, but differences in the effect between early and late elderlies remain unclear.
Methods: Ninety-seven patients diagnosed with putaminal hemorrhage (age, ≥65 years; hematoma volume, ≥30 mL) were included in this retrospective analysis and separated into three treatment groups: craniotomy surgery (CR), endoscopic surgery (EN), and non-surgical (NS) groups. The patients were additionally subdivided into two groups according to age: patients aged 65-74 years ("early elderlies") and patients aged ≥75 years ("late elderlies"). Their clinical data and outcomes at discharge were compared using statistical analyses.
Results: The CR and the EN groups were associated with lower mortality rates (P < 0.001), lower modified Rankin Scale (mRS; P = 0.007), and lower National Institutes of Health Stroke Scale (NIHSS; P = 0.029) compared to the NS group. Early elderlies in the CR and EN groups with ICH scores of 3 also had significantly better outcomes (P = 0.001). The proportion of patients with mRS ≤ 4 was highest in the early elderlies of the EN group (P = 0.553). Although significant differences in the change of NIHSS scores between the early and late elderlies was not observed, significantly improved NIHSS scores were observed in the EN group compared to the NS group, even in the late elderlies (P = 0.037).
Conclusion: The evacuation of deep-seated intracranial hematomas using the endoscope might improve functional outcomes and mortality, regardless of age.
