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. Methods: A retrospective, observational and longitudinal study of 35 patients operated on for astrocytoma grade III at Hospital Guillermo Almenara between 2003 and 2009 was carried out. Data were collected from medical records, operative reports, and telephone interviews. Patients with anaplastic astrocytomas were classified according to prognostic risk group, treatment type, and surgery extent. SPSS 25.0 was used for the analysis. Results: Of a total of 124 patients with astrocytoma, 28.2% (35/124) had a grade III astrocytoma, with an average survival of 34.8 months. According to the clinical prognosis group, the survival of the low, medium, and high-risk groups was 46.7, 28.1, and 8.5 months, respectively. Regarding the type of treatment, the group with the longest survival was surgery + radiotherapy (39.5 months), followed by surgery + radiotherapy + chemotherapy (29.3 months), and the one with the lowest survival was surgery alone (6.5 months). According to the extension of the surgery, the highest survival was obtained by the total resection group (46.2 months), while the lowest survival was for the partial resection group (13.9 months). Conclusions: The average survival of patients operated on for grade III astrocytomas in our hospital was 34.8 months, with the best prognostic factors being the \"low risk\" clinical group, the combined treatment of surgery + radiotherapy, and total resection. Its classification into prognostic risk groups based on pre-surgical clinical data helps us predict survival.

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. Clinical case: We present the case of a 56-year-old obese male patient with a history of high blood pressure who was admitted with an extensive intracerebral hematoma in the basal ganglia of the right hemisphere. A right frontoparietotemporal craniotomy was performed, with the opening of the Sylvian fissure and approach through the insula, managing to evacuate the hematoma. The initial evolution was stationary, so it was necessary to remove the bone platelet, thereby achieving a favorable evolution, then performing the cranioplasty. Conclusion: Surgical treatment of intracerebral hemorrhage of the basal ganglia through the transylvian transinsular approach has shown good results in several case series in terms of evacuation degree and functional outcome.

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. Methods: The COBOT has a remote-controlled electronic gripper and includes a special needle holder made using 3D printing technology; This holds the interventional instrument, needles, and other surgical elements. The instrument-loaded forceps are oriented and progressed toward intracorporeal therapeutic target points used in interventional radiology and radiation therapy procedures, the COBOT boasts operational precision. Results: Its operation was verified by simulating the interventional action in models in animal tissue, and experimental surgery laboratory. Conclusions: It is concluded that the robot arm can perform assistance functions in radiological and stereotaxic neuroradiological interventionism with a good level of precision, reducing the doctor's exposure to X-rays.

Methods: Descriptive, retrospective, and cross-sectional study in patients 18 years of age and older, hospitalized in the Neurosurgery Service of Hospital Cayetano Heredia (HCH), between April 2020 and March 2021. Data were collected from medical records, registry care diary, and the HCH laboratory computer system. Results: Of the total number of patients (n=116), the male sex (73.28%) and the age between 18 to 59 years (73.28%) predominated. 35.34% had at least one NI, being the most common pneumonia (18.97%) and surgical site infections (SSI) 18.10%.

The Glasgow Coma Scale (GCS) is the most widely used TBI severity classification; however, it assesses the functional status of the brain resulting from highly heterogeneous lesions and has little accuracy. The Neurological Severity Classification System (NSC System), a clinical-tomographic instrument designed to overcome lesion heterogeneity, assesses brain function and structure in determining the severity of BTI. Methods: Observational, prospective, and cross-sectional study in adults with BTI from the emergency service of the Cayetano Heredia Hospital, April - August 2020. It included patients aged 18 years or older with acute BTI. The NSC system was compared with the GCS in the BTI classification. Results: Of 29 patients, 82.76% were male and 82.76% were between 18 and 64 years old. The severity of the TBI through the NSC System was very mild 6.70%, mild 17.24%, moderate 51.72%, severe 17.24%, and critical 6.70%. There was an association between the NSC System and the Rotterdam Computed Tomographic Score (RCTS) (p = 0.005), a moderate positive correlation of the NSC System with the RCTS (Rho 0.6773, p = 0.0001), an association between the NSC System and the indication for neurosurgical intervention (p = 0.002), as well as high sensitivity-specificity in the distinction of severity categories with the NSC System, and lower GCS performance. Conclusions: The NSC clinical-tomographic system improves the determination of the severity of BTI in comparison with GCS and provides an excellent relationship with the indication for neurosurgical intervention.

The symptoms are not specific, but in the event of trauma it is necessary to suspect this entity to carry out a timely diagnosis and treatment, since being the product of the skull base fracture it can cause communication with the outside, and the appearance of cerebrospinal fluid (CSF) leak. Clinical Case: a 38-year-old male patient who suffers trauma from a pyrotechnic explosion near his right ear, when handling a pyrotechnic object (whistle) during the New Year, presenting severe pain, slight bleeding in the right ear, feeling faint and holocranial headache that increased in a standing position; likewise, he presents high-flow aqueous secretion (CSF) from the right ear. Brain and skull base tomography (CT) showed air in the intracranial cavity, fracture of the skull base, and the ossicles of the right middle ear. Conservative management was performed using rest and lumbar drainage, presenting a satisfactory evolution. Conclusion: Pneumocephalus is a frequent and expected complication of trauma with a skull base fracture. Its early and timely diagnosis using skull base CT is essential to define therapeutic measures. Accidents due to the misuse of pyrotechnics continue to be a relevant problem in our country. Knowing and disseminating its consequences can help raise awareness in the population. Keywords: Pneumocephalus, Skull Base, Intracranial Pressure, Cerebrospinal Fluid Leak.

Resection of these tumors is a neurosurgical challenge. The combined partial petrosectomy approach associated with a sub-temporal approach is a technique described by various authors; however, its performance is considered highly complex. We report the case of a petroclival meningioma operated successfully in our hospital using a combined presigmoid and subtemporal transtentorial transpetrosal approach. Clinical case: 33-year-old female patient with a clinical picture of headache, nausea, and gait disturbance. Brain magnetic resonance imaging showed a large right petroclival tumor (4.2x3.9x3.8cm) that displaced the brainstem and secondary hydrocephalus. The hydrocephalus was treated with a ventricular peritoneal shunt. Then, the tumor was resected using a combined presigmoid and subtemporal transpetrosal approach, a technique that allowed adequate exposure of the tumor, achieving complete resection, without intraoperative complications. Postoperative evolution was favorable, with no sequelae. Conclusion: The combined presigmoid and transtentorial subtemporal transpetrous approach for petroclival meningiomas is an effective and feasible technique to perform in our environment. The support of technology such as Neuronavigation, the ultrasonic aspirator, intraoperative monitoring, and adequate experience in skull base surgery are fundamental factors for the success of this surgery.
