Long-term outcome of stereotactic aspiration, endoscopic evacuation, and open craniotomy for the treatment of spontaneous basal ganglia hemorrhage: a propensity score study of 703 cases

BACKGROUND: To compare the long-term therapeutic effects of stereotactic aspiration (SA), endoscopic evacuation (EE), and open craniotomy (OC) in the surgical treatment of spontaneous basal ganglia hemorrhage and explore the appropriate clinical indications for each technique. METHODS: Multiple-treatment inverse probability of treatment weighting (IPTW)-adjusted logistic regression analysis was performed to evaluate the therapeutic effects of these techniques. The primary and secondary outcomes were 6-month modified Rankin Scale (mRS) and mortality rates, respectively. RESULTS: A total of 703 patients were ultimately enrolled. For the entire cohort, the 6-month mortality rate was significantly higher (OR 2.396, 95% CI: 1.865–3.080), and the 6-month functional outcome was significantly worse (OR 1.359, 95% CI: 1.091–1.692) for SA than that of EE. The 6-month mortality rate for OC was significantly higher (OR 1.395, 95% CI: 1.059–1.837) than that of EE. Further subgroup analysis was stratified by initial hematoma volume and Glasgow Coma Scale (GCS) score. The mortality rate for SA was significantly higher for patients with hematoma volume of 20–40 mL (OR 6.226, 95% CI: 3.848–10.075), 40–80 mL (OR 2.121, 95% CI: 1.492–3.016), and ≥80 mL (OR 5.544, 95% CI: 3.315–9.269) than in the same subgroups of EE. The functional outcomes for SA were significantly worse than that of EE for hematoma volume subgroups of 40–80 mL (OR 1.424, 95% CI: 1.039–1.951) and ≥80 mL (OR 4.224, 95% CI: 1.655–10.776). The mortality rate for SA was significantly higher than that of EE for the GCS score subgroups of 6–8 (OR 2.082, 95% CI: 1.410–3.076) and 3–5 (OR 2.985, 95% CI: 1.904–4.678). The mortality rate for OC was significantly higher for the GCS score of 3–5 subgroup (OR 1.718, 95% CI: 1.115–2.648), and a tendency for a higher mortality rate of 6–8 subgroup (OR 1.442, 95% CI: 0.965–2.156) than that of EE. CONCLUSIONS: EE can decrease the 6-month mortality rate and improve the 6-month functional outcomes of spontaneous basal ganglia hemorrhage in patients with a hematoma volume ≥40 mL. EE can decrease the 6-month mortality rate of spontaneous basal ganglia hemorrhage in patients with a GCS score of 3–8.
