Mixed Reality Assisted Neurosurgery

Presenting Author:
Dr. Carlos Yepes, MD

In Common Solutions Based on Monitors and Static Screens, they require surgeons to look away from the surgical field to compare and analyze images while manipulating an instrument in the patient's target area.
RA and MR can provide a solution that facilitates the integration and transfer of information from images to the surgical field in a simple and user-friendly way. Thus, they can complement the concept of surgical navigation in specialized areas, by providing a 3D model with anatomical details that can be visualized without losing sight of the surgical field and that could even be superimposed on the real surface and updated in real time, giving additional information for faster and safer decision making.

A Novel Technique to Reduce The Amount of Postoperative Pneumocephalus After Evacuation of Chronic Subdural Hematoma.

Presenting Author:
Dr. Khalid Mohammad Ashour, MBBCh, MS, FEBNS

Chronic subdural hematoma (Ch. SDH) is a common pathology in elderly patients. We describe a novel technique to reduce the amount of postoperative pneumocephalus  by using a continuous saline irrigation through a cannula inserted via the burr hole till the last stitch of wound closure.

Case Report: Trapped Four Ventricle, Atypical Presentation of Tuberculous Meningitis

Presenting Author:
Dr. Karen Sofia Tejada-Angarita, MD

Tuberculosis is a public health disease that affects the world population. Meningeal tuberculosis is the clinical presentation with the highest morbidity and mortality. One of the most frequent complications of this pathology is communicating hydrocephalus; however, up to 5% of the other types of hydrocephalus can be manifested, and it can pose a significant challenge in its management.

Cerebral Hydatid Cyst: About a Multipe Recurrence Case

Presenting Author:
Dr. Myriam Naceur, MD

Literature reports suggest very rare cases of cerebral hydatid cysts (HC), representing 2% of all intra cranial lesions, even in counties where the disease is endemic. HC diagnosis is usually based on a pathognomonic computed tomography (CT) pattern. Surgical resection remains the best treatment option with a good prognosis. But outcome may become pejorative in case of recurrence.Case description:We report the case of a 16-year-old boy, who presented with intracranial hypertension syndrome and right hemiparesis.

Trigeminal Neuralgia in Pregnancy Patients: Case Report

Presenting Author:
Dr. Andres Felipe Pineda-Martinez, MD

Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder, more frequently found in women (60%), however it is rarely associated with pregnant women and to our knowledge, there is one single case-report in literature (1).  TN in pregnancy brings management challenges, since pharmacotherapy is limited by fetal risks and adverse effects.

The "Nine" Syndrome with Upward Gaze Palsy after Resection of a Pontomesencephalic Cavernous Malformation

Presenting Author:
Dr. Camilo Armando Benavides, MD

Brainstem syndromes constitute a special clinical entity due to the complex array of neurological signs involving cranial nerve nuclei and projection fibers. The recently published “nine” syndrome, is defined by the presence of complete horizontal gaze palsy ipsilateral to lesion and contralateral adduction gaze palsy (one-and-a-half syndrome), peripheral type facial paralysis and hemiparesis, hemianesthesia or hemiataxia. The nine syndrome is a rare clinical entity described in 2013, as a subtype of the eight-and-a-half-syndrome-plus. Variations of the nine syndrome constitute a rare clinical neurological diagnosis.

Intraoperative Communication Failures in Neurosurgical Procedures Related to Personal Protection Equipment During the COVID-19 Pandemic

Presenting Author:
Dr. Maria José Pachon, MD

COVID-19 pandemic has exposed surgical teams to unprecedented working conditions. Due to the latent risk of transmission, the use of personal protection equipment (PPE) is required to prevent airborne infections. Consequently, pitfalls and discomfort in communication have been elucidated during surgical cases. This study aimed to assess neurosurgical team perceptions on the impact of PPE on intraoperative communication.

Focal, Extranodal Primary Polymorph Hemangioendothelioma Treated With Endovascular Embolization Plus Resection Surgery

Presenting Author:
Dr. Esteban Ramirez-Ferrer, MD

The hemangioendothelioma is a rare vascular tumor that was first described in 1982. It is a tumor with a biological borderline behavior  as an intermediary pathology between benign hemangioma and malignant angiosarcoma . Up to date, less than 10 cases of properly called PH can be found in the literature, most of them from the lymph nodes and a rare case from maxillary soft tissue PH, and only a few cases of primary extranodal presentation have been described in the literature. Given the small number of cases found, the natural history of the disease has not been elucidated. The utility of previous endovascular embolization combined with open resection has not been described in the context of a vascular malignancy with high bleeding rate during open surgery to achieve total resection.

Immunocompetent Patient with a Brain Abscess Caused by Nocardia Beijingensis in Latin America: A Case Report

Presenting Author:
Dr. David M. Solano-Varela, MD

Nocardia species are not commonly referred as primary infectious entities but rather as opportunistic cases of Nocardia spp. in immunocompetent individuals are rare. Here we present the first case of N. beijingensis infection of the central nervous system in an immunocompetent in Latin America.

Safe Withdrawal Period of Anticoagulant Therapy in Patients Requiring Surgical Drainage in Chronic Subdural Hematomas

Presenting Author:
Dr. Humberto Madriñán Navia, MD.

Surgical treatment of chronic subdural hematoma (CSH) in patients with anticoagulation is a frequent encounter in the neurosurgical rounds. Due to population aging and comorbidities neurosurgeons face the surgical decision in the presence of anticoagulant medications. Debates on describing safe withdrawal period and time-to-restart medication following drainage are continuous in clinical scenarios.
