Background: Arteriovenous malformation (AVMs) is a collection of dysplsatic plexiform vessels that is supplied by one or more arterial feeders and drained by one or more venous channels. AVMs may have a pure plexiform nidus or contain a mixed plexiform fistulous nidus.
Objective: To evaluate cerebral AVMs postoperative endovascular embolization by intervention, clinical and radiological outcome  in a sample of Egyptian patients.
Patients and Methods: This was a  retrospective  study of all consecutive patients who had underwent endovascular embolization for cerebral AVMs between December 2006 up to April 2021.One hundred sixty-nine (169) patients (91 female and 78 males) with cerebral arteriovenous malformations were treated by embolization at the Neurointervention Unit at Al-Hussein Hospital University
Results: The mean age in our study was 32.85 years with a range of 6-80 years, and the standard deviation was 14.875 years . The sex distribution showed slight higher incidence in females (53.8%) than in males (46.2%), and twenty eight patients (16.6%) were with family history of cerebral AVMs. The most common presnetation was intracranial hemorrhage (prsented as weakness), seizure came second, and headache came third Other neurological deficits (focal deficits , learning disability  and cognitive impairment) were due to AVM itself. were significant difference in nidus diameter, and the Spetzler and Martin grading of the cerebral AVMs after embolization in comparison to before embolization.
Conclusion: The endovascular treatment of the cerebral AVMs was safe, efficient and achieved high rates of total and near total occlusion.
