BACKGROUND and Purpose: Whether surgical treatment is necessary for small volume of thalamic hemorrhage is not clear. Our study was to test whether robot-assisted surgery can improve the prognosis of small volume of thalamic hemorrhage, and to provide surgical basis for treatment of small volume of thalamic hemorrhage. METHODS A retrospective study of thalamic hemorrhage patients with hematoma volume ranged from 5ml to 15ml treated in our department from December 2015 to December 2018. The patients were divided into operation group and non-operation group. The general data, types of hematoma, incidence of complications, Scandinavian Stroke Scale (SSS) and modified Rankin Scale (mRS) were recorded and analyzed. RESULTS Retrospectively, 84 cases were included by inclusion criteria. 35 cases were found in the operation group and 49 cases were found in the non-operation group. At 90 days after onset, the mortality was 11.4% in the operation group and 4.1% in the non-operation group(P>0.05). The SSS score of the operation group (43.3±8.5) was higher than non-operation group (36.1±10.0) (P<0.05). The mRS score of the operation group (2.9±0.3) was lower than non-operation group (3.7±0.2) (P<0.05). The incidence of pneumonia (8.6% vs. 28.6%), renal dysfunction in the operation group (14.3%) was lower than that in the non-operation group (34.7%)(P<0.05). The incidence of central high fever (5.7% vs. 12.2%), stress ulcer (11.4% vs. 16.3%) and ion disturbance (20.0% vs. 26.5%) had no significant difference between two groups (P>0.05). CONCLUSIONS Robot-assisted drainage of thalamic hemorrhage can improve prognosis and reduce the incidence of pneumonia and renal dysfunction.
