OBJECTIVE The cases of two patients who presented with sylvian aqueductal obstruction caused by venous lesions (an ectatic vein and a developmental venous anomaly, which are uncommon causes of obstructive hydrocephalus) are reported. CLINICAL PRESENTATION A 42-year-old man presented with chronic headache and behavior abnormalities. Magnetic resonance(More)
Intracranial aneurysms are usually described in the adult population. They are rare in childhood, representing 1–5% of all intracranial aneurysms [5, 7, 10]. Aneurysms in this population exhibit features that differ significantly from those in adults, including a higher incidence of unusual anatomic locations, male predominance, and a higher incidence of(More)
Basilar artery is the second most common site of fenestration, after the anterior communicating region. It is believed this variation predisposes a patient to posterior aneurysm formation and increases the complexity of the surgical anatomy. Endovascular management has become the first option to treat these aneurysms. We retrospectively evaluated eight(More)
Total surgical resection is the treatment of choice for choroid plexus tumors. However, the hypervascular nature of such lesions imposes challenges to the surgical treatment. Preoperative embolization for intracranial tumors has been widely used in an attempt to reduce blood loss, but rarely with choroid plexus tumors. We describe the first case of(More)
OBJECTIVE To prospectively evaluate the results of endoscopic choroid plexus cauterization (ECPC) and ventriculoperitoneal shunts (VPSs) in infants with hydranencephaly or near hydranencephaly. METHODS We prospectively collected clinical data from all untreated hydranencephalic and near hydranencephalic children from October 2006 to March 2008. All(More)

PURPOSE Spinal dural arteriovenous fistulas (sDAVF) are the most common spinal vascular lesions. The arterialization of the recipient vein results in venous hypertension and chronic ischemia. Intravascular injection of acrylic glue in order to occlude the draining vein is the principle of endovascular treatment, but a significant portion of embolization(More)
INTRODUCTION The authors present a retrospective series of their clinical experience in the treatment of cavernous dural arteriovenous fistulas (DAVF) by direct transorbital puncture of the cavernous sinus as an alternative to the endovascular approach. METHODS Between October 2012 and September 2014, eight patients harboring cavernous DAVF underwent(More)
To describe a novel configuration of pipeline embolization device for internal carotid bifurcation region aneurysm, named horizontal stenting. A 64-year-old woman, with visual deficit, harboring a large wide-necked aneurysm located at the junction between left internal carotid artery and left A1 segment of anterior cerebral artery, was submitted to(More)
A 63-year-old woman performed a magnetic resonance imaging because of persistent headache, which demonstrated a left parietal convexity tumor. A digital subtraction angiography was performed in order to plan the preoperative embolization. It showed the persistence of primitive trigeminal artery associated with the persistence of stapedial artery1,2. The(More)
