Surgical evacuation of spontaneous cerebellar hemorrhage: Comparison of safety and efficacy of suboccipital craniotomy and robotic-assisted stereotactic hematoma drainage

Abstract

ObjectiveThis study compared the efficacies of robotic-assisted stereotactic hematoma drainage and suboccipital craniotomy (SC) in patients with spontaneous cerebellar hemorrhage (SCH). MethodsThis retrospective study included 138 non-comatose patients with SCH (Glasgow Coma Scale score [GCS] >8), divided into the SC and Robotic Stereotactic Assistance (ROSA) groups. The study recorded and analyzed complications and prognoses 90 days after ictus. ResultsThe inclusion criteria were met by 138 patients: 61 in the SC and 77 in the ROSA group, with no significant differences in sex, age, GCS score, hematoma volume, and the time from ictus to operation. The time of operation was greater in the SC group (287.53±87.57) than in the ROSA group (60.54±20.03). The evacuation rate (ER) was greater in the SC group (93.20±1.58) than in the ROSA group (89.13±2.75). The incidence of pneumonia and stress ulcers, as well as the length or costs of medical services, were lower in the ROSA group than in the SC group. Ninety days after ictus, the modified Rankin Scale (mRS), Glasgow Prognostic Scale (GOS), and Karnofsky Performance Scale (KPS) scores significantly differed between the groups. The rate of good prognosis in the ROSA group was significantly higher compared with that in the SC group. The incidence of balance disorders was lower in the ROSA group than in the SC group; no statistically significant difference was found in the incidence of dysarthria and swallowing disorders. ConclusionRobotic-assisted stereotactic hematoma drainage may be suitable for non-comatose and stable condition patients with SCH. This procedure improves prognosis 90 days after ictus, lowers the incidence of pneumonia and stress ulcers, and reduces the length and costs of medical services.
