RESUMO
Suboccipital decompressive craniectomy with or without resection of necrosis is the preferred treatment for space-occupying cerebellar infarctions with neurological deterioration due to brainstem compression and obstructive hydrocephalus. We herein present our experience with treating space-occupying cerebellar infarctions successfully using endoscopic necrosectomy. A total of 27 patients were admitted to our hospital due to cerebellar infarctions between April 2021 and November 2023. Four patients required surgical interventions due to a drop in consciousness level or compression of the fourth ventricle and brainstem with acute hydrocephalus confirmed by a computed tomography (CT) scan. Three patients were performed endoscopic necrosectomy through a burr hole in a supine-lateral position. Removing most of the necrotic tissue was possible, resulting in early decompression of the fourth ventricle and brainstem. Endoscopic necrosectomy is less invasive than suboccipital decompressive craniectomy. An endoscopic necrosectomy can be performed for patients with unstable health conditions in a supine-lateral position. Therefore, endoscopic necrosectomy might be an effective method for treating patients with space-occupying cerebellar infarctions and poor general condition, although an objective evaluation of the extent and degree of removal is needed.
