Endovascular treatment with coils of aneurysm of the anterior communicating artery, angiographic control, and evolution according to packing density: case series.

Enviado por admin el Mié, 11/15/2023 - 18:48

The goal of this study is to present the outcomes of endovascular treatment performed on a group of patients diagnosed with ruptured aneurysms in the anterior communicating artery. The effectiveness of the treatment will be assessed based on the degree of packing observed in both immediate and subsequent angiography control.

Selective posterior corpus callosotomy in a child with Lennox–Gastaut Syndrome: case report

Enviado por admin el Mié, 11/15/2023 - 18:24

In epilepsy refractory to medical treatment which presents multiple and bilateral epileptogenic foci such as Lennox Gastaut syndrome (LGS) the surgical alternative is disconnection surgery such as callosotomy. Posterior callosotomy is indicated in cases of atonic seizures with posterior resection, leading to better seizure control. We present the case of a patient with Lennox Gastaut syndrome who required a posterior callosotomy achieving complete control of atonic seizures.

Central diabetes insipidus post-ventriculostomy. case report

Enviado por admin el Mié, 11/15/2023 - 18:11

Diabetes insipidus is a rare complication in cerebral vascular pathology. Although its presentation is associated with surgery for pituitary tumors, few cases have been reported after the evacuation of cerebral hemorrhages. We present a patient with Diabetes insipidus in a patient with ventriculostomy due to intraventricular hemorrhage.

Experience in lumbar microdiscectomy at the Guillermo Almenara Irigoyen Hospital 2018 -2021

Enviado por admin el Vie, 06/30/2023 - 21:19
Herniation of the nucleus pulposus (HNP) is the leading cause of sciatica. The standard diagnostic test is magnetic resonance imaging and treatment can be conservative or surgical. The most common surgical technique is lumbar microdiscectomy. The objective of the study was to know the epidemiological and clinical profile, as well as the surgical results of patients undergoing lumbar microdiscectomy at the Almenara Hospital from January 2018 to August 2021.

Beginnings of endoscopy spine surgery in Peru

Enviado por admin el Vie, 06/30/2023 - 21:10
In recent years, spinal endoscopy has become increasingly common in our setting; however, its use is not recent. The first reported cases date back to the early 2010s by a team from the Cayetano Heredia Hospital in charge of Drs. Wesley Alaba and Jerson Flores. Although other minimally invasive procedures such as nucleoplasty, nucleolysis, or percutaneous rhizotomies had already been used since the 2000s, it was not until 2011 that endoscopy was used for the first time in a standardized manner in spinal surgery with the endoscope as the only element of vision, successfully resecting a vertebral lesion.

Prognostic factors in the survival of patients operated of astrocytoma grade III at the Guillermo Almenara Hospital Lima- Peru. 2003-2009

Enviado por admin el Lun, 06/20/2022 - 02:15
Anaplastic astrocytoma (AA) or grade III is a primary brain tumor, astrocytic, malignant, and diffusely infiltrating. The survival of patients depends on several clinical and treatment factors, being this unknown in our environment. The objective of this study was to determine the survival of patients operated on for grade III astrocytoma and the impact of preoperative and postoperative prognostic factors.

Glioma of the optic pathway and hypothalamus in a child: a case report

Enviado por admin el Lun, 06/20/2022 - 02:03

Gliomas of the optic nerve, visual pathway, and hypothalamus are treated as a single entity, being considered benign neoplasms in pediatric age, grade I according to the WHO. 25% of them are confined to the optic nerve, 40-75% involve the optic chiasm, and 33-60% are posterior lesions. Most do not present symptoms, but in the case of presenting, the most frequent is loss of vision. The gold standard for diagnosis is magnetic resonance imaging (MRI) with contrast. The first line of treatment is chemotherapy, with surgery used for nerve decompression, if necessary.

Giant occipital encephalocele in a newborn; surgical treatment. Case report

Enviado por admin el Lun, 06/20/2022 - 01:21

Neural tube defects (NTD) are congenital malformations that are caused by the lack of fusion of the neural tube during the embryonic period, exposing the nervous tissue to the outside. There are different types, and they can be cranial (anencephaly and encephalocele) and spinal (spina bifida). The encephalocele is a protrusion or herniation of the intracranial content, through the bony defect of the skull. In this article, we report the case of a patient diagnosed with occipital encephalocele, while reviewing the neurosurgical treatment performed in our hospital.

Articulated robotic arm for assistance in interventional radiology

Enviado por admin el Lun, 03/28/2022 - 15:58

Robotic technology has helped medicine to reduce exposure time and offer greater efficiency and precision in surgical interventions. The goal of using an articulated robotic arm for X-ray (Rx) guided minimally invasive surgery and interventional assistance is to reduce direct and secondary radiation on physicians. The use of a collaborative robotic arm (COBOT) that replaces the operating arm of the surgeon-interventionist physician to avoid exposure to X-rays is described.

Intracerebral hemorrhage of basal ganglia, surgical management through transinsular transylvian approach. case report

Enviado por admin el Lun, 03/28/2022 - 15:48

Acute spontaneous intracerebral hemorrhage is a life-threatening disease of global importance, with a poor prognosis and few effective treatments. For supratentorial intracerebral hemorrhage, early evacuation (<24 hours after hemorrhage onset) with standard craniotomy is considered lifesaving in deteriorating patients. In cases where the hemorrhage is less than 1 cm from the cortical surface, the clinical benefit is even greater.
