Background: We present our experience with managing 13 cases of vein of Galen aneurysm with a special focus on endovascular strategies. This clinical review deals with the multivariable clinical presentation of vein of Galen aneurysms and the role of transarterial endovascular treatment. Methods: Thirteen patients diagnosed with vein of Galen aneurysms have been reviewed. Clinical presentation, diagnostic modalities and treatment strategies are also documented for each. MRI and three-dimensional CT angiogram (3D CTA) were performed for all patients. Transarterial embolization with Histoacryl was performed in 8 patients proved to have true vein of Galen aneurysmal malformation (VGAM). Results: Clinical presentation was variable including hydrocephalus, headaches, heart failure, coma, epilepsy, and even left orbital swelling. MRI demonstrated large vein of Galen aneurysms in all the cases. 3D CTA demonstrated true VGAM in 10 patients. Two cases proved to have vein of Galen varices. Endovascular treatment was conducted successfully in 8 patients and resulted in arrest of head growth, resolution of headaches and improvement of cardiac condition. Conclusion: The transarterial approach proved to be a successful way of management of true VGAM that yielded better outcomes.
