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.

Successful endovascular management of a ruptured cerebral aneurysm in an infant patient

Cerebral aneurysms in pediatric age are rare. In early childhood, they appear before the age of 2 years and are related to a high incidence of injuries along the middle cerebral artery, in its distal part, and in the vertebrobasilar system. The etiology can be idiopathic, traumatic, and fungal. Aneurysm obliteration should be as early as possible in patients with low surgical risk.

Endovascular treatment of ruptured and non-ruptured brain aneurysms is an appropriate option in most patients. In narrow neck aneurysms, treatment with coils is sufficient, but in those with wide necks, the use of stent-assisted coils or flow diverters is necessary. Endovascular treatment of intracranial aneurysms is effective and provides complete occlusion in up to 85% of cases, however, there are cases of incomplete obliteration or recanalization that require treatment.
