Study on the image characteristics of arteriovenous malformations on multi-slide computed tomography scan performed in Viet-Czech Friendship hospital

Abstract

Objective: To analyze images of cerebral arteriovenous malformations with cerebral bleeding on multi-slide CT scan Method: Cross-sectional description of 23 patients due to cerebral arteriovenous malformation on multi-slide CT at the Department of Diagnostic Imaging of Viet Tiep hospital from 01/2021 to 10/2022. Results: the most common age was from >60. Male/Female = 2.2/1. Cerebral parenchymal hemorrhage, rate 73.3%, lobar hemorrhage 87%, deep internal bleeding 13.0%. The location of the vascular malformation was mainly above the cerebellar tent 91.3%. Small size AVM 78.3%. Focal malformations fed by branches of the middle cerebral artery accounted for 56.5%. Most of the malformations were supplied with blood by many branches, accounting for 52.2%. Most of the malformations were drained by a superficial draining vein 47.8%. Conclusion: Multi-slice CT scan allows the radiologist to diagnose and provides treatment strategies for cerebral arteriovenous malformation.
