Objective To explore the clinical effect of stereotactic minimally invasive surgery on the treatment of small amount of thalamic hemorrhage.Methods A retrospective analysis was performed on 110 patients with small amount of thalamic hemorrhage(hematoma volume 6-15mL)admitted to our hospital from October 2019 to May 2022.Stereotactic minimally invasive surgery and conservative treatment were performed in the treatment group(55 cases)and the control group(55 cases),respectively.All patients were evaluated using the National Institutes of Health Stroke Scale(NIHSS),Glasgow Coma Score(GCS),and the expanded Glasgow Prognosis(GOS-E)score.Changes in the NIHSS score at admission,2 weeks after treatment and 4 weeks after treatment were compared between the two groups.Changes in hematoma volume and GOS-E score before and after treatment were compared as well.The incidence of complications and the NIHSS and GOS-E scores at 6 months after discharge were also compared.Results The 2-week and 4-week NIHSS score and GOS-E score in the treatment group were significantly better than those of the control group(P<0.05).The 3-day and 7-day hematoma volume in the both groups were significantly smaller than those at admission(P<0.05),and which in the treatment group were significantly smaller than those of the control group(P<0.05).The incidence of intracranial infection in the treatment group was significantly higher than that of the control group(P<0.05).The incidence of hydrocephalus,pulmonary infection,and lower extremity thrombosis in the treatment group was significantly lower than that of the control group(P<0.05).After 6 months of follow-up,the NIHSS score in the treatment group was significantly lower than that of the control group(P<0.05),and the GOS-E score in the treatment group was significantly higher than that of the control group(P<0.05).Conclusion The stereotactic minimally invasive surgery can significantly improve the outcome and prognosis of patients with small amounts of thalamic hemorrhage compared to the conservative treatment.
