Minimally Invasive Surgery for Spontaneous Cerebellar Hemorrhage: A Multicenter Study.
(Journal Article;Multicenter Study)
BACKGROUND: Spontaneous intracranial hemorrhage (ICH) of the cerebellum can be life threatening because of mass effect on the brainstem and fourth ventricle. Suboccipital craniectomy is currently the treatment of choice for cerebellar ICH evacuation. Minimally invasive surgery (MIS) is currently being investigated for the treatment of supratentorial ICH. However, its utility for cerebellar ICH is unknown. The aim of this multicenter, retrospective cohort study is to evaluate the outcomes of MIS for cerebellar ICH. METHODS: We retrospectively reviewed the records of all patients with cerebellar ICH who underwent MIS using either the Apollo or Artemis Neuro Evacuation Device (Penumbra Inc., Alameda, California, USA) at 3 institutions from May 2015 to July 2018. Data from each contributing center were deidentified and pooled for analysis. RESULTS: The study cohort comprised 6 patients with a median age of 62.5 years. The median pre- and postoperative Glasgow Coma Scale scores were 10.5 and 15, respectively. The median degree of hematoma evacuation was 97.5% (range, 79%-100%). There were no procedural complications, but 1 patient required subsequent craniectomy (retreatment rate 17%). The median discharge modified Rankin scale score was 4, including 3 patients who improved to functional independence at follow-up durations of 3 months. Two patients died from medical complications (mortality rate 33%). CONCLUSIONS: MIS could represent a reasonable alternative to conventional surgery for the treatment of appropriately selected patients with cerebellar ICH. However, further studies are needed to clarify the perioperative and long-term risk to benefit profiles of this technique.
