Abstract:

Objective The study aimed to investigate the efficacy and complications of neuronavigation frameless stereotactic puncture and drainage in the treatment of a small amount of deep intracerebral hematoma. Methods A retrospective analysis was performed on 54 patients（15 ~ 30 mL）with deep cerebral hemorrhage treated in the Department of Neurosurgery of the second affiliated Hospital of Zhengzhou University from January 2019 to December 2021. 28 patients treated with neuronavigation frameless stereotactic puncture and drainage were taken as the study group and 26 patients with conservative treatment were taken as the control group. GCS score 1 week after treatment，mRS score 1 month later and ADL score 3 months later were applied to evaluate the efficacy and prognosis，and the complications of the two groups were compared and analyzed. Results The hematoma clearance rate after 1 week，GCS score after 1 week，mRS score after 1 month and ADL grade after 3 months in the study group were superior to the conservative group（P < 0.05）. The incidence of pulmonary infection and venous thrombosis of lower extremities in the control group was higher than study group（P < 0.05）. The inci⁃ dence of rebleeding and hydrocephalus in the study group was similar to control group（P > 0.05）. Conclusion For patients with a small amount of deep cerebral hemorrhage with neurological dysfunction，neuronavigation frame⁃ less stereotactic drainage can promote the early recovery of neurological function and reduce complications.
