Experience in the surgical treatment of pituitary adenomas at the Guillermo Almenara Hospital in 2019-2020

Enviado por admin el Mié, 07/01/2020 - 00:00

Pituitary adenomas constitute 25% of the primary benign neoplasms of the brain and can be functional or non-functional, or depending on their size they can be microadenomas, macroadenomas, and giant adenomas. They are mainly treated by surgery using the either transcranial or transsphenoidal approach. We show the experience in the surgical treatment of pituitary adenomas in the Guillermo Almenara National Hospital from January 2019 to May 2020.

Malfunction of the valvular shunting system in children. Experience in the Neurosurgery Department of the Baca Ortiz Pediatric Hospital, Quito-Ecuador, 2016-2019

The prevalence of valve dysfunction (VD) in pediatric centers is high. A descriptive observational study was carried out, the objective of which was to find factors: epidemiological characteristics of hydrocephalus and other derivatives of the ventricle-peritoneal shunt system (VPSS) associated with VD. We studied all the diagnoses of VD for 3 years in the Neurosurgery Service of the Baca Ortiz Pediatric Hospital, in Quito, Ecuador.

Embolization of ruptured giant aneurysm of the medium cerebral artery followed by surgical evacuation of intracerebral hematoma

Early endovascular therapy of a ruptured giant aneurysm associated with intracerebral hematoma avoids the need for clipping of the aneurysm, thereby avoiding the need for greater brain retraction, edema, transient clipping, as well as the possibility of intraoperative rupture, thus achieving timely and adequate management of this pathology.

Experience in diagnostic and treatment of central nervous system tumors in children less than 2 years at the Baca Ortiz Pediatric Hospital, Quito-Ecuador, 2016-2019

Enviado por admin el Lun, 03/23/2020 - 01:16

Tumors of the central nervous system (CNS) in children between 0 and 2 years of age are infrequent, so their diagnosis and treatment constitute an important challenge for every pediatric neurosurgical center, to which is added the comorbidities typical of this age. The objective of this study was to describe the diagnostic and therapeutic experience of a neurosurgical Department of national reference in Quito, Ecuador.

Neurosurgery as a medical discipline has always been on the cutting edge of technology and the latest advancements. It’s not a surprise why modern neurosurgeons actively utilize various social media platforms, in order to share the latest news or showcase interesting cases they face daily. From Twitter to LinkedIn neurosurgical professionals of the world share the knowledge and connect with each other in order to advance their skills to the next level.

Isolated intracranial Rosai-Dorfman disease: case report

Enviado por admin el Lun, 03/23/2020 - 00:46

Rosai-Dorfman disease is a pathology of histiocytic, proliferative, idiopathic and benign type characterized by sinus histiocytosis and massive lymphadenopathy. The most frequent clinical presentation is painless bilateral cervical lymphadenopathy. Extra-nodal involvement occurs in 43% of cases and central nervous system (CNS) involvement in 4%. We present a case of this rare entity.

Minipterional interfascial approach for microquirurgical treatment of ruptured and unruptured anterior circulation aneurysms. Initial experience in the Dos de Mayo National Hospital in Lima - Peru

Enviado por admin el Mié, 11/27/2019 - 22:50

The Minipterional craniotomy is reliable, less invasive, it maintains the advantages of the pterional approach but avoids greater exposure of the parenchyma and tissue manipulation. Aneurysms of the anterior circulation, ruptured and unruptured, can be treated safely and effectively with limited bone extraction, good cosmetic results and good temporomandibular function.

Aqueductoplasty with stent placement by neuroendoscopy for the management of a cyst of the IV ventricle in a case of neurocisticercosis

Enviado por admin el Mié, 11/27/2019 - 22:29

Endoscopic aqueductoplasty with stent placement in the Silvio aqueduct is an effective measure in cases of isolated cyst in the fourth ventricle, achieving good clinical and imaging evolution compared to other therapeutic options. We present the case of a 34-year-old patient with a history of neurocysticercosis who received antiparasitic treatment and the placement of a DVP, presenting multiple dysfunction with severe dilatation of the IV ventricle. 

Endovascular management of non-ruptured intracranial aneurysms with flow diverter devices. First experience in Peru.

Enviado por admin el Sáb, 08/17/2019 - 20:01

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.

Curative transvenous embolization of a challenging ruptured thalamic arteriovenous malformation using Onyx: Case report.

Enviado por admin el Sáb, 08/17/2019 - 19:26

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.
