Transsphenoidal endoscopic surgical treatment of pituitary tumors at the Cayetano Heredia National Hospital in Lima Peru: outcomes of a series of cases

Enviado por admin el Jue, 12/31/2020 - 17:47

Transsphenoidal endoscopic surgery has become a surgical procedure of choice for the treatment of pituitary tumors. The objective of the present study was to describe the demographic, clinical characteristics, complications, and postoperative results of the patients who underwent transsphenoidal endoscopic resection. We present our results of this technique in patients operated from January 2016 to August 2018 at Neurosurgery Department of the Cayetano Heredia National Hospital.

Endoscopy-assisted microsurgery in the resection of epidermoid tumor of the pontocerebellar angle

Enviado por admin el Jue, 12/31/2020 - 17:40

Intracranial epidermoid tumors are rare, slow-growing, and histologically benign congenital neoplasms. The microsurgical approach with endoscopic assistance is described as a minimally invasive technique that facilitates the work of the neurosurgeon in the complete resection of an epidermoid tumor located in the cerebellopontine angle. We present a case where we use a combined microscopic and endoscopy technique.

Microsurgical resection of a pontine cavernoma through a far lateral infratentorial supracerebellar approach

Enviado por admin el Jue, 12/31/2020 - 17:33

Cavernomas on the posterolateral pontomesencephalic surface can be approached from an extreme lateral supracerebellar infratentorial corridor, although the theory is scarce. The brainstem has a dense concentration of nuclei and fibers that are responsible for a high rate of morbidity when treating brainstem lesions. The objective of this work is to demonstrate the safe microsurgical resection technique for the complete removal of a pontine cavernoma.

Neurosurgical treatment of unstable cervical spine due to rheumatoid arthritis: case series

Enviado por admin el Lun, 09/14/2020 - 00:48
Rheumatoid arthritis (RA) is a systemic disease characterized by synovitis, which causes damage to the ligaments and joints. The cervical region is the region of the spine most affected, with neck pain the most frequent symptom. The three forms of presentation are atlantoaxial subluxation, cranial settlement, and subaxial subluxation. The clinical evolution of patients treated conservatively is poor, with surgery being a key element to prevent the progression of neurological deterioration.

Recurrent lumbar disc prolapse, causative factors and outcome in bangladeshi people

Enviado por admin el Lun, 09/14/2020 - 00:41
Recurrent lumbar disc prolapses (RLDP) is not uncommon after surgery. The incidence of RLDP varies from 5-18% across the different populations in the world. The exact cause of recurrence is not known but the weakness of the annular tissue due to previous surgery, exposure to repetitive lifting, heavy work causing axial load, advanced age, smoking, are some of them. The study aims to evaluate the causative factors of RLPD and the outcome of surgeries in Bangladeshi peoples.

Hydrocephalus in pediatric population. Experience in the Neurosurgery Department of the Baca Ortiz Pediatric Hospital, Quito-Ecuador, 2016-2019

Enviado por admin el Lun, 09/14/2020 - 00:31
Hydrocephalus is one of the most common pathologies in the daily care of a Pediatric Neurosurgery Service, so it is important to document the context of its presentation to improve therapeutic behavior. The objective of the present study was to describe the demographic variables, as well as the type, treatment, morbidity, and mortality of patients with hydrocephalus.

Vertebral hydatidosis: case report

Enviado por admin el Lun, 09/14/2020 - 00:23
Vertebral hydatid cyst is a rare disease with an incidence rate of 0.2-1%. In the spinal cord, it can cause pain and severe disability due to compression and instability. Magnetic resonance imaging (MRI) shows characteristic lesions in T1 and T2. The combination of medical anthelmintic treatment and surgery for cyst excision is the most used strategy.

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

Enviado por admin el Mar, 06/30/2020 - 23:55
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

Enviado por admin el Mar, 06/30/2020 - 23:48

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.
