[Endovascular treatment of spinal dorsal intradural arteriovenous fistulas].

Background: The dorsal spinal intradural arteriovenous fistulas (DSIAF) are infrequent and complex injuries are underdiagnosed condition and disability. The aim is to present our experience in the endovascular management.

Methods: A retrospective and prospective study of patients with DSIAF treated by endovascular therapy (EVT) with n-butyl-cyanoacrylate during the period 2007-2013.

[Invasive management of trigeminal neuralgia. 8 years experience].

Background: Trigeminal neuralgia (TN) is characterized by stereotyped repetitive, unilateral pain, referred as an electric shock, triggered by the stimulation of the rami of the trigeminy nerve. It presents more frequently in women. The aim is to know the efficacy of surgical treatment of TN against pain by means of microvascular decompressive technics (MDT) and balloon percutaneous microcompression (BPM).

[Endoscopic third ventriculostomy for chronic communicating hydrocephalus in adults].

Background: Shunt devices to treat hydrocephalus are associated with a malfunction of 81 % at 12 years and 10 % of infection. The objective was to assess safeness and efficacy of endoscopic third ventriculostomy (ETV) for the treatment of chronic communicating hydrocephalus.

Methods: Eight patients with chronic communicating hydrocephalus were included in a period between September, 2012 and April, 2013.

[Treatment of endovascular aneurysms associated with fenestration of the basilar artery. A case report].

The fenestration of the basilar artery is an uncommon anatomical variant that may be associated with saccular aneurysms; however this association is rare. We report the case of a patient who presented with subarachnoid hemorrhage that was successfully treated by coil embolization and review the literature.

[Prognostic factors in elderly patient meningioma].

Background: Frequently, therapeutic decisions must be made in order to manage meningioma in geriatric patients. This study analyzes the prognostic factors, as well as the Clinical Radiological Grading Score (CRGS) as a complement to make therapeutic decisions.

Methods: A retrospective study was conducted between 2009 and 2010.

[Endovascular management of residual intracranial aneurysms after surgical clipping].

Objectives: To identify and evaluate the cerebral aneurysm remnants after clipping and the endovascular treatment in our institution.

Methods And Materials: We made a clinical ambispective collection of all aneurysms microsurgically clipped during four years and we analyzed their endovascular treatment.

Results: There were 290 cerebral aneurysms; in 270 a digital subtraction angiography was made.

[Trigeminal-cavernous fistula. Report of a case and review of the literature].

Persistent primitive trigeminal artery is a rare anatomical variant resulting from the absence of obliteration of the embryonic trigeminal artery. The shunt between the persistent primitive trigeminal artery and the cavernous sinus is called trigeminal-cavernous fistula. We report the case of a woman with a trigeminal-cavernous fistula secondary to head trauma who was treated by transarterial embolization.

[Device for percutaneous insertion of a distal catheter in ventriculo-atrial shunt. Technical report].

Introduction And Objectives: A ventriculo-atrial shunt is indicated for the treatment of some hydrocephalus cases. The distal catheter is usually inserted into the right atrium through cervical venous dissection. Percutaneous insertion has been described with success; however its use is not widespread.

[Endovascular treatment of non-galenic pial arteriovenous fistulas].

Introduction And Objectives: Pial arteriovenous fistulas are infrequent vascular malformations. They are generally congenital and their natural history is ominous. The objective of this work is to describe our experience in their endovascular management and to review the existing literature.

[Endoscopic endonasal transsphenoidal approach for growth hormone-producing pituitary adenomas. Preliminary results].

Background: An endoscopic endonasal transsphenoidal approach is reported as less invasive, allowing an earlier discharge. Published series have never focused on its use in acromegalic patients.

Objective: To assess the effectiveness of an endoscopic endonasal transsphenoidal approach in the management of growth hormone-secreting adenomas.

[Chronic nasal obstruction: ethmoidal encephalocele in an adult patient].

Nasal obstruction is a frequent cause of referral to the ear, nose and throat specialist. When this symptom is resistant to medical management and common causes have been ruled out, the presence of neural structures should be investigated In the nasoethmoidal meningoencephalocele, a congenital defect of the ethmoid lamina cribrosa allows the herniation of the intracranial contents into the nasal fossa. The key to clinical diagnosis is the presence of nasal obstruction with rhinorrhea and recurrent meningitis.

Genetic similarity between cysticerci of Taenia solium isolated from human brain and from pigs.

Mitochondrial (mt) cox1 and ribosomal ITS1 DNA sequences from Taenia solium cysticercus isolates from pigs and cysticerci (racemose and cellulose types) from patients with neurocysticercosis were amplified by the polymerase chain reaction (PCR). The amplicons were sequenced in order to determine the genetic relationship between these types of cysticerci. Phylogenetic trees were constructed and evolutionary distances were calculated.

[Surgical treatment for trigeminal neuralgia].

We treated 50 patients at the Hospital de Especialidades, Centro Médico Nacional La Raza, IMSS, in Mexico City, with trigeminal neuralgia by two procedures: a) microvascular decompression of the trigeminal nerve with asterional craniectomy, or b) compression of Gasser's nodule by percutaneous puncture. Each patient was allowed to choose one of the procedures after informed consent. Twenty two patients underwent percutaneous puncture, while 28 patients underwent microvascular decompression.
