Abstract
Surgical vascular diseases of the Central Nervous System are considered nowadays a sub-specialization of neurosurgery. They comprehend intracranial aneurysms, AVM´s and Cavernous angiomas. These conditions are a continous challenger for neurosurgeons, because even with the permanent advances in diagnosis, surgery, endovascular treatment and specialized Intensive Care Units, the number of dead or severity disabled patients is still very high. We present a series of 73 patients operated on at the Neurosurgical Department of the Asociación Española in Montevideo (June 1994-April 2000), consisting of 58 aneurysms, 11 AVM´s and 4 Cavernous Angiomas.

Key words
Aneurysms, arteriovascular malformations, cavernous angiomas
