Endovascular treatment of non-ruptured intracranial aneurysms with flow diverter devices is a technique that currently has many indications for its use. We present a retrospective review of consecutive cases treated with flow diverters at our institution. Since October 2012 to April 2017, twenty-one patients were treated with a total of 29 non-ruptured aneurysms.

Dural arteriovenous fistulas (DAVF) are vascular lesions that require a high suspicious index for its diagnosis, because of their wide variety of clinical manifestations, moreover, invasive procedures such as digital subtraction angiogram (DSA) is the gold standard and is required for its diagnostic confirmation.

Craniocervical arteriovenous fistulas (AVF) are rare entities. A high index of suspicious is required for its diagnosis. Surgery, embolization or both are available treatments. We present the case of a young woman who presented with syncope. Additional studies revealed the presence of a craniocervical junction AVF.

Arteriovenous malformations (AVM) are typically treated by arterial approach. In selected cases, venous embolization is an option with good results. We present the case of a ruptured thalamic arteriovenous malformation treated successfully with transvenous embolization using Onyx, achieving complete obliteration of the nidus.

Cerebral aneurysms are formed due to a weakness in the arterial wall, this cause a dilation and the subsequent risk of rupture, conditioning subarachnoid hemorrhage, being one of the causes of cerebrovascular disease with higher risk of morbidity or death. We presented the first brain revascularization microsurgery for the treatment of a complex cerebral aneurysm performed at the Dos de Mayo National Hospital.
