Objective. To analyze our experience in neurosurgical vascular disease in patients under one year. Materials and Methods. Between 1/1/89 and 1/6/09 we treated at the Department of Neurosurgery of the Hospital Nacional de Pediatría Juan P. Garrahan 235 patients with vascular malformation of the central nervous system. Of these 19 (n = 19; 8%) were infants under one year, 11 were males and 8 females, mean age at diagnosis 4.5 months (range from prenatal to 1 year). We evaluated all charts and neuroradiologic studies of each patient. Results. All patients were studied with initial CT scan except one patient with Vein of Galen Aneurysmal Malformation (VGAM) who was diagnosed antenatal by ultrasound. The types of lesions were 6 VGAM (4 choroidal type and 2 mural type), 6 Arteriovenous Malformations (AVM), 2 Pial Arteriovenous Fistulas (1 brain and 1 spinal), 1 spinal Dural Arteriovenous Fistula, 1 Cavernoma, 1 Aneurysm and 2 Embryologic Dural Sinus Malformations at the posterior fossa. Conclusion. It is remarkable variability and complexity of vascular malformations of the central nervous system in the first year of life. It is necessary to integrate the endovascular neurosurgical team, not only for diagnosis but also to complement or facilitate the treatment of any of theses vascular disease. The most frequent vascular malformations in our group were the VGAM and the AVM followed by AV Fistulas.
