So far, very few cases of spontaneous intraventricular pneumocephalus have been reported. We present the case of a patient who developed spontaneous intraventricular pneumocephalus, which required a craniotomy for surgical correction. Clinical Case: A 59-year-old female patient with a history of left suboccipital craniotomy and resection of the left vestibular Schwannoma who after 2 years presented headache of 3 weeks duration and aphasia of expression. On examination: Mild expressive aphasia, surgical scar with no evidence of cerebrospinal fluid (CSF) leakage. Brain tomography (CT) showed pneumoventricle in the frontal and temporal horns of the left lateral ventricle and deviation from the midline; radionuclide cisternography was negative for CSF fistula and CSF analysis was normal. A left subtemporal craniotomy was performed, finding a bone defect in the petrous portion of the temporal bone above the internal auditory canal associated with a meningocele of the medial base of the skull, which was sealed with bone wax, fat, fascia lata, and biological glue. Conclusion: The first case of spontaneous intraventricular pneumocephalus without identifiable CSF fistula is described, which made this case extremely rare. The treatment performed was a surgical correction of the meningocele through a subtemporal extradural approach, and the patient presented a favorable evolution with the improvement of the aphasia.

The surgery is performed by transsphenoidal resection (TSR) or transcranial resection (TCR); TSR can be by microscopy or endonasal endoscopy. Subarachnoid hemorrhage (SAH) associated with a pituitary tumor is rare and can be: Preoperative, due to pituitary apoplexy with rupture of the arachnoid into the basal cisterns, Intraoperative, due to vascular injury during surgery or rupture of an unidentified aneurysm; and Postoperative, due to residual tumor hemorrhage, or bleeding from small vessels adhered to the tumor capsule.1, 2 Clinical case: 46-year-old male patient with a clinical picture of bitemporal hemianopsia with left predominance. Magnetic resonance imaging and brain tomography showed a pituitary macroadenoma. Endoscopic endonasal resection of the tumor was performed without intraoperative opening of the arachnoid. On the 1st day, the evolution was favorable with improved visual fields, but on the 2nd day, the patient presented headache and increased visual deficit. Brain CT showed SAH in basal cisterns. Tomography angiography showed no vascular injury. The patient evolved favorably with the improvement of visual fields. Conclusion: Subarachnoid hemorrhage associated with a pituitary adenoma has various causes that can be preoperative, intraoperative, and postoperative. The incidence of postoperative SAH as a complication of endonasal endoscopic resection is low, but it can affect the patient's prognosis. Excessive traction on the tumor capsule should be avoided.

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.

It is characterized by the presence of hemorrhage and postoperative edema that is difficult to manage, leading to significant sequelae and in some cases death. Pre and postoperative conditions play an important role in WGS, as well as factors related to surgery such as modification of tumor and peritumoral blood flow, altered coagulation, among others. Clinical case: 12-year-old patient with a diagnosis of anaplastic astrocytoma who underwent partial surgical resection, without presenting complications. At 48 hours, the patient presented clinical signs of intracranial hypertension, the brain tomography revealed bleeding in the surgical bed and significant perilesional edema. Barbiturate coma, neuroprotective measures, and anti-edema treatment were induced. The patient remained in the ICU for 23 days, leaving the ICU on a 5-point Glasgow Coma Scale, dependent on mechanical ventilation so far. Conclusion: This case shows the rapid deterioration and important sequelae that a patient with glioma surgery can present. Complete resection is not always possible. Therefore, when faced with incomplete resection or a biopsy, neurosurgeons must consider this syndrome, as well as its implications and repercussions in the immediate postoperative period; To assess the risk/benefit when planning surgery and act early, if this syndrome occurs.

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%. NI were associated with traumatic brain injury (TBI) (p=0.005), spinal cord trauma (SCI) (p=0.020), surgery (p=0.032), stay in Intensive Care Units (ICU) (p=0.000), hospital stay greater than seven days (p=0.000) and mortality (p=0.049).
