Abstract

Objectives: Evaluation of clinical and radiological features of haemorrhage in cerebellar arteriovenous malformation (AVM) ruptures. Methods: A retrospective study of 31 patients who were diagnosed with cerebellar hemorrhage due to AVM and underwent surgery in Bach Mai hospital from January 2021 to January 2023. Results: 16M:15F with mean age of 38 (9-58 years old). Most patient has an initial GCS > 9 (80.3%). Headache was the most prevalent symptom (96.8%), but no patients showed convulsions; followed by cerebellar haemorrhage (77.4%), intraventricular haemorrhage (29%), ventricular dilatation (38.7%). The most common location was the suboccipital area (35.5%), size < 3 cm (51.6%), 3-6 cm (48.4%), malformed mass supplied by one single source of circulation (58.1%), deep venous drainage (38.7%), mass with diffused nature (41.9%). Spetzler-Martin grading: 7 patients grade I, 15 grade II and 9 grade III. Conclusions: Hemorrhage by cerebellar AVM rupture has a typical clinical manifestation with intracranial hypertension, absent of convulsions, the blood supply to the AVM can be from one or more sources, deep venous drainage, and diffused nature.
