Objectives: To describe clinical features and MSCT imaging in cerebral hemorrhage patients due to ruptured cerebral arteriovenous malformation. Methods: A descriptive cross-sectional study of 36 cases with ruptured cerebral arteriovenous malformation (AVM) who were treated at Bach Mai Hospital from October 2019 to July 2021. Results: Mean age was 43±14,7 years old, male/female ratio was 1,27/1. Medical history with headache and epilepsy were 69,44% and 25%, respectively.

The percentage of hematoma sizes smaller than 3cm, from 3 to 6cm and greater than 6cm were 58.3%, 38.9%, and 2.8% respectively. The most common ruptured AVM size were small and medium. The ruptured AVM feeding vessels originate from midle cerebral artery were 52,78%. The AVM had 1 to 3 feeding arteries were 91,67%. The AVM with pure one draining vein was 72,2%. Conclusion: The predominant age group in ruptured AVM was 40 years old and above (63,9%); the mean age was 43 ± 14,7, male/female ratio was 1,27/1. The common hemorrhagic location were in cerebral lobules (85,72%), hematoma sizes smaller than 3cm with pure one draining vein was 72,2%.
