Objective To investigate the safety of double target minimally invasive surgery combined with nimodipine in the treatment of patients with thalamic hemorrhage breaking into ventricle and its influence on NIHSS score. Methods From January 2017 to January 2020, 54 patients with thalamic hemorrhage ruptured into ventricles in our hospital were selected as the research data, and they were randomly divided into 27 cases in each group. The control group was treated with external drainage of lateral ventricle alone, and the observation group was treated with stereotactic double target minimally invasive puncture and drainage of hypothalamic hematoma. The changes of NIHSS score, ADL score, nerve injury index and trauma stress index in different stages of treatment were determined. Results The complication rate of the observation group was 7.41%, lower than that of the control group 29.63%, P<0.05; after treatment, NSE, NGF, β-EP, Cor in the observation group were decreased, and lower than those in the control group, P<0.05; after treatment, NIHSSL score of the observation group was decreased, lower than that of the control group, ADL score was increased and higher than that of the control group, P<0.05. Conclusion For patients with thalamic hemorrhage breaking into ventricles, stereotactic double target minimally invasive puncture drainage combined with thalamic hematoma and nimodipine treatment may further improve the neurological function and patients’ quality of life, and the operation safety is high, the recovery of traumatic stress is improved, the recovery of nerve injury is quick, and the complications are less, which is worthy of promotion.
