Introduction: Arteriovenous malformations (AVMs) are vascular abnormalities that consist of multiple fistulous
connections between arteries and veins without a normal intervening capillary bed. AVMs are thought to be congenital. 90%
of all AVMs are supratentorial.
Objective: The aim of this study is to evaluate the efficacy, safety and outcome of endovascular management of cerebral
Patients and methods: The study was performed in the Department of Neurosurgery, Qena Faculty of Medicine South Valley
University. Twenty patients with cerebral AVMs were enrolled in this study. Those 20 patients received endovascular
treatment (EVT) as the primary modality of treatment.
Out of 20 patients treated by EVT, 17(85%) patients had good recovery without neurological deficits at hospital discharge
(GOS 5) while three (15%) patients had moderate disability (GOS 4) in the form of hemiparesis.
Conclusion: In this thesis, EVT was an effective and safe technique for treatment of cerebral AVMs showing a high cure rate
either as asingle treatment modality or as a preprocedural technique facilitating other forms of treatment and improving
outcome of the cases.
