In recent years, the incidence of craniocerebral trauma has increased, making it one of the important causes of death and disability in neurosurgery patients. The decompressive craniectomy (DC) after severe craniocerebral injury has become the preferred treatment for patients with severe craniocerebral injury, but the incidence of postoperative hydrocephalus has become a difficult problem in clinical treatment. This study observed the changes of nerve growth factor (NGF), adrenocorticotropic hormone (ACTH), and arginine vasopressin (AVP) levels in the CSF after DC in patients with craniocerebral injury and analyzed the relationship between the three indicators and communicating hydrocephalus. The results showed that the levels of NGF, ACTH, and AVP in patients with cranial injury after DC were significantly higher than those in healthy subjects, and subdural effusion, traumatic subarachnoid hemorrhage (tSAH), and the levels of NGF, ACTH, and AVP in the CSF were independent risk factors for communicating hydrocephalus. Monitoring the levels of NGF, ACTH, and AVP is of great significance for clinicians to judge the occurrence of traffic hydrocephalus, evaluate the prognosis of patients with craniocerebral injury after DC, and guide clinical treatment.

Abstract The aim of this study was to identify the predictors of postoperative hydrocephalus in patients with lateral ventricular tumors (LVTs) and to guide the management of perioperative hydrocephalus. We performed a retrospective analysis of patients who received LVT resection at the Department of Neurosurgery, Zhongnan Hospital of Wuhan University between January 2011 and March 2021. Patients were divided between a prophylactic external ventricular drainage (EVD) group and a non-prophylactic EVD group. We analyzed the non-prophylactic EVD group to identify predictors of acute postoperative hydrocephalus. We analyzed all enrolled patients to determine predictors of postoperative ventriculoperitoneal shunt placement. A total of 97 patients were included in this study. EVD was performed in 23 patients with postoperative acute obstructive hydrocephalus, nine patients with communicative hydrocephalus, and two patients with isolated hydrocephalus. Logistic regression analysis showed that tumor anterior invasion of the ventricle (P = 0.020) and postoperative hemorrhage (P = 0.004) were independent risk factors for postoperative acute obstructive hydrocephalus, while a malignant tumor (P = 0.004) was an independent risk factor for a postoperative ventriculoperitoneal shunt. In conclusion, anterior invasion of the lateral ventricle and postoperative hemorrhage are independent risk factors for acute obstructive hydrocephalus after LVT resection. Patients with malignant tumors have a greater risk of shunt dependence after LVT resection.

Background: Ruptured intracranial dermoid cysts are extremely rare. Standard treatment consists of endonasal decompression or craniotomy with evacuation and copious irrigation of subarachnoid spaces to remove any disseminated cystic contents. Disseminated fat particles in the subarachnoid space may be the cause of further sequalae, including the subsequent development of chemical meningitis and hydrocephalus. Here, we present a case of ruptured suprasellar dermoid cyst treated with craniotomy for emergent optic nerve decompression, followed by postoperative hydrocephalus successfully treated with lumbar drain.Case description: We describe a 30-year-old man with a history of migraines who presented with acute onset of headache, photophobia, nausea, vomiting, and vision loss in the left eye. Head CT and brain MRI demonstrated a ruptured suprasellar dermoid cyst with associated mass effect on the optic nerves and frontal lobes as well as fat attenuation material within the subarachnoid spaces. The patient underwent left frontotemporal craniotomy for cyst resection and developed non-obstructive hydrocephalus on postoperative day 1, refractory to external ventricular drainage. Placement of a lumbar drain cleared the subarachnoid space of debris derived from the ruptured dermoid cyst, and the hydrocephalus resolved. The patient did not require permanent CSF diversion.Conclusions: Intracranial dermoid cysts are uncommon, and rupture is a rare event. Standard surgical treatment with craniotomy for evacuation may leave disseminated dermoid contents and fat particles throughout the subarachnoid spaces. We highlight a case of ruptured suprasellar dermoid cyst with postoperative communicating hydrocephalus treated with lumbar drain when external ventricular drain (EVD) was ineffective. Review of the current literature reveals inconsistent findings on the effects of remaining fat particles. In cases with clinical evidence of increased intracranial pressure due to non-obstructive hydrocephalus attributable to chemical meningitis, temporary lumbar drainage is an option to be considered before committing the patient to permanent shunting.

Background: An endoscope-assisted technique was recently introduced to microsurgery (MS) and may compensate for the disadvantages of MS for deep-seated lesions. This study was performed to identify the effectiveness and safety of endoscopic-assisted microsurgery (EAM) and share our experience of EAM for pediatric cases with pineal region tumors.Method: We retrospectively analyzed the clinical data of consecutive pediatric cases with pineal region tumors treated by EAM or MS from January 2016 to June 2020. These data included the patient population, clinical manifestations, preoperative examination findings, surgical approach, pathological results, and clinical outcomes. The clinical outcomes were analyzed in the EAM group and MS group with a focus on the gross total resection (GTR) rate, postoperative hydrocephalus remission rate, and Karnofsky performance score (KPS). Studies on the surgical management of children with pineal region tumors in the last decade were reviewed.Result: Eighteen children successfully underwent tumor resection via MS (n = 8) or EAM (n = 10). The children's mean age was 11.4 ± 4.7 years, and the male to female ratio was 7:2. Seventeen patients (94.4%) complicated preoperative hydrocephalus, and 16 (88.9%) presented headache with nausea and/or vomiting. The pathological examination revealed germ cell tumors in 11 (61.1%) patients, neuroepithelial tumors in 4 (22.2%) patients, and a pineoblastoma, arachnoid cyst, and atypical teratoid rhabdoid tumor in 1 (5.6%) patient each. GTR was more commonly achieved in the EAM than MS group (80.0 vs. 50.0%, respectively), and the postoperative hydrocephalus remission rate was higher in the EAM than MS group (87.5 vs. 50.0%, respectively). At a mean follow-up time of 23.6 ± 11.5 weeks, the mean improvement of the KPS 6 months postoperatively was greater in the EAM than MS group (24.0 ± 9.7 vs. 17.5 ± 7.1 points, respectively).Conclusion: EAM combines endoscopic and microsurgical techniques and can be safely and effectively performed to achieve GTR of pineal region tumors in pediatric patients. In children with pineal region tumors who have obstructive hydrocephalus, EAM could improves hydrocephalus remission rates by checking and clearing the midbrain aqueduct under visualization.

OBJECTIVE Postoperative hydrocephalus occurs in one-third of children after posterior fossa tumor resection. Although models to predict the need for CSF diversion after resection exist for preoperative variables, it is unknown which postoperative variables predict the need for CSF diversion. In this study, the authors sought to determine the clinical and radiographic predictors for CSF diversion in children following posterior fossa tumor resection. METHODS This was a retrospective cohort study involving patients ≤ 18 years of age who underwent resection of a primary posterior fossa tumor between 2000 and 2018. The primary outcome was the need for CSF diversion 6 months after surgery. Candidate predictors for CSF diversion including age, race, sex, frontal occipital horn ratio (FOHR), tumor type, tumor volume and location, transependymal edema, papilledema, presence of postoperative intraventricular blood, and residual tumor were evaluated using a best subset selection method with logistic regression. RESULTS Of the 63 included patients, 26 (41.3%) had CSF diversion at 6 months. Patients who required CSF diversion had a higher median FOHR (0.5 vs 0.4) and a higher percentage of postoperative intraventricular blood (30.8% vs 2.7%) compared with those who did not. A 0.1-unit increase in FOHR or intraventricular blood was associated with increased odds of CSF diversion (OR 2.9 [95% CI 1.3–7.8], p = 0.02 and OR 20.2 [95% CI 2.9–423.1], p = 0.01, respectively) with an overfitting-corrected concordance index of 0.68 (95% CI 0.56–0.80). CONCLUSIONS The preoperative FOHR and postoperative intraventricular blood were significant predictors of the need for permanent CSF diversion within 6 months after posterior fossa tumor resection in children.

Abstract Background: Hydrocephalus may occur after subependymal giant cell astrocytoma (SEGA) resection. In existing literatures, SEGA almost always occurred in patients with tuberous sclerosis complex (TSC), however, many SEGA also occurred alone in our Chinese pediatric patients. Objective: To discuss the risk factors of postoperative hydrocephalus following SEGA resection and the relationship between SEGA and TSC in Chinese children.Materials and methods: A total of 35 children (≤18-year-old) who underwent SEGA resection were selected. From 3 months postoperatively until December 2020 all patients received telephone or clinical follow-up. Related risk factors were first screened by univariate analysis and then analyzed by multivariate logistic regression.Results: The ratio of males to females was 3:2 and the mean age was 11.6 years. Twenty cases were associated with TSC and 15 were not. The mean maximum diameter of the SEGA for patients with and without associated TSC was 49.7mm and 30.5mm, respectively (Z=-3.293, P=0.001). Twenty-eight patients had preoperative hydrocephalus. Sixteen patients developed postoperative hydrocephalus, and amongst these, 2 did not have hydrocephalus before surgery. Multivariate analysis showed that association with TSC [odds ratio (OR), 18.81, P=0.048] and tumor resection rate (OR, 0.042, P=0.025) were independent risk factors for postoperative hydrocephalus. Conclusion:SEGA could be associated with TSC or appear alone. The maximum diameter of SEGA associated with TSC is larger than that without TSC. Hydrocephalus is a common onset symptom and might recur following SEGA resection. Association with TSC and tumor resection rate are risk factors for postoperative hydrocephalus.

Abstract Objectives The aim of this study was to explore the rates and potential risks of surgical site infection (SSI) after posterior fossa surgery for tumour resection in children. Methods We retrospectively reviewed our local paediatric (age < 16 years) database for all cases of posterior fossa (PF) brain tumour surgery between November 2008 and November 2019. We collected patient demographics, tumour histology/location, and the event of postoperative surgical site infection. Results Overall, 22.1% (n=15) developed SSI out of sixty-eight children undergoing PF surgery for resection of brain tumours; 73.3% of them had a confirmed diagnosis of medulloblastoma. There was no statistically significant difference in the age (5.1 ± 0.60 vs. 6.2 ± 0.97 years; p=0.47) and duration of operation (262 vs. 253 min; p = 0.7655) between the medulloblastoma group and other tumours. Although the rate of postoperative hydrocephalus was higher in the medulloblastoma group (12.9% vs. 0%), this was not associated with increased SSI. Rates of CSF leak between the 2 groups were not different. Conclusion Medulloblastoma as a pathological entity seems to carry higher risk of postoperative surgical site infection compared to other types of paediatric posterior fossa tumours. Further larger studies are required to look into this causal relationship and other risk factors that might be involved.
