Endoscopic Ventricular Lavage in Pediatric Pyogenic Cerebral Ventriculitis Associated with Shunt: Outcomes and Technical Notes. World Neurosurg 2024:S1878-8750(24)00397-8. [PMID: 38484968 DOI: 10.1016/j.wneu.2024.03.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 03/04/2024] [Accepted: 03/05/2024] [Indexed: 04/19/2024]
Abstract
OBJECTIVE Pyogenic cerebral ventriculitis (PCV) is a rare infectious entity characterized by a potent inflammatory reaction of the ventricular ependyma, which in most cases leads to death. We aim to present the technical note and protocol, based on our center's 10-year experience of the use of endoscopic ventricular lavage (EVL) in pediatric patients with PCV and ventricular peritoneal shunt. METHODS For this study, all pediatric patients (<16 years) with VP shunts and PCV who were treated with EVL between January 2012 and January 2022 were included. RESULTS Thirty-four pediatric patients with ventriculitis were analyzed. The median age was 6 years, with 61.7% being male. Most consultations occurred on Day 2 of symptoms. Fever (38.2%) and altered consciousness (26.5%) were the most common initial symptoms. Early ventriculitis was observed in 67.7% of patients. Pathogen identification in the initial cerebrospinal fluid sample was 70.6%, while samples from ventricular peritoneal shunt yielded 23.53% and catheter culture 79.4%. Gram-positive bacteria, mainly S.epidermidis (44.1%), was the most commonly isolated agent. EVL was performed in 73.5% on the second or third day. Reinfection occurred in 23.5%, and 26.5% of patients died. Concordance analysis showed 85.3% agreement between LP and catheter tip samples. Functionality improved, with 55.88% achieving a Lansky score of 90. Early ventriculitis was associated with better Lansky scores. CONCLUSION EVL can be a useful tool in the management of PCV in cases with VP shunts. Our study suggests a higher chance of isolating an infection-causing germ in the catheter tip culture specimen compared to the cerebrospinal fluid culture. However, future studies with a larger number of patients, or multicentric studies are required for further analysis.

Abstract
Neuroendoscopy procedures in pediatrics have expanded beyond the endoscopic third ventriculostomy. As such, a direct and angled endoscope allows further visualization around the corner, capturing the surrounding anatomy. Intraoperative live images look different than radiological images. Hence, in this single institutional experience, we correlate neuroradiology images with intraoperative intraventricular endoscopic views of the third-fourth ventricle, pituitary, pineal gland, cerebral aqueduct, and foramen magendie and luschka. Our collective case series reveals a few interesting case scenarios of normal and abnormal findings during the procedure. Careful navigation of the neuroendoscope is crucial to prevent injury to the neurovascular bundle. A close relationship with normal anatomy from radiological imaging is necessary to prevent it from getting lost once inside the ventricular cavity.

Abstract
INTRODUCTION Gram-negative rod (GNR) bacterial ventriculitis is a rare complication of shunt-dependent hydrocephalus, often requiring an extended and invasive treatment course. Accumulation of purulent material, as well as empyema and septation formation, limits circulation of antibiotics and infection clearance. Supplementation of standard care with neuroendoscopic-guided intraventricular lavage with lactated Ringer solution and fenestration of septations may facilitate infection clearance and simplify the eventual shunt construct required. Here, the utility of serial lavage for ventriculitis is described in a population of shunt-dependent neonates and infants at high risk for morbidity and mortality. METHODS Five infants with shunt-dependent hydrocephalus and subsequent GNR ventriculitis were treated with standard care measures with the addition of serial neuroendoscopic lavage. A retrospective chart review was performed to collect patient characteristics, shunt dependency, and shunt revisions within a year of ventriculitis resolution. RESULTS Patients demonstrated a mean 74% decrease in cerebrospinal fluid (CSF) protein following each neuroendoscopic lavage and trended toward a shorter time to infection clearance in comparison to previously published literature. Patients required 0-2 shunt revisions at 1-year follow-up following hospitalization for shunt-related ventriculitis (mean 0.8 +/- 0.8). CONCLUSIONS Serial neuroendoscopic lavage is an effective technique, used alone or in combination with fenestration of septations, to reduce the CSF protein and bacterial load in the treatment of ventriculitis, decreasing time until eradication of infection. Serial lavage may reduce the risk of future shunt malfunction, simplify the future shunt construct, and decrease duration of infection.

Abstract
BACKGROUND Considering the high reoperation rate in degenerative lumbar spondylolisthesis (DLS) patients undergoing lumbar surgeries and controversial results on the risk factors for the reoperation, we performed a systematic review and meta-analysis to explore the reoperation rate and risk factors for the reoperation in DLS patients undergoing lumbar surgeries. METHODS Literature search was conducted from inception to October 28, 2022 in Pubmed, Embase, Cochrane Library, and Web of Science. Odds ratio (OR) was used as the effect index for the categorical data, and effect size was expressed as 95% confidence interval (CI). Heterogeneity test was performed for each outcome effect size, and subgroup analysis was performed based on study design, patients, surgery types, follow-up time, and quality of studies to explore the source of heterogeneity. Results of all outcomes were examined by sensitivity analysis. Publication bias was assessed using Begg test, and adjusted using trim-and-fill analysis. RESULTS A total of 39 cohort studies (27 retrospective cohort studies and 12 prospective cohort studies) were finally included in this systematic review and meta-analysis. The overall results showed a 10% (95%CI: 8%-12%) of reoperation rate in DLS patients undergoing lumbar surgeries. In surgery types subgroup, the reoperation rate was 11% (95%CI: 9%-13%) for decompression, 10% (95%CI: 7%-12%) for fusion, and 9% (95%CI: 5%-13%) for decompression and fusion. An increased risk of reoperation was found in patients with obesity (OR = 1.91, 95%CI: 1.04-3.51), diabetes (OR = 2.01, 95%CI: 1.43-2.82), and smoking (OR = 1.51, 95%CI: 1.23-1.84). CONCLUSIONS We found a 10% of reoperation rate in DLS patients after lumbar surgeries. Obesity, diabetes, and smoking were risk factors for the reoperation.

Surgical Antimicrobial Prophylaxis in Neonates and Children Undergoing Neurosurgery: A RAND/UCLA Appropriateness Method Consensus Study. Antibiotics (Basel) 2022; 11:antibiotics11070856. [PMID: 35884111 PMCID: PMC9311924 DOI: 10.3390/antibiotics11070856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 06/17/2022] [Accepted: 06/22/2022] [Indexed: 11/25/2022] Open
Abstract
Pediatric neurosurgery is a highly specialized branch of surgery in which surgical site infections (SSIs) are potentially serious complications that can also adversely affect a good surgical outcome, compromising functional recovery and, in some cases, even putting the patient’s life at risk. The main aim of this consensus document is to provide clinicians with a series of recommendations on antimicrobial prophylaxis for neonates and children undergoing neurosurgery. The following scenarios were considered: (1) craniotomy or cranial/cranio-facial approach to craniosynostosis; (2) neurosurgery with a trans-nasal-trans-sphenoidal approach; (3) non-penetrating head injuries; (4) penetrating head fracture; (5) spinal surgery (extradural and intradural); (6) shunt surgery or neuroendoscopy; (7) neuroendovascular procedures. Patients undergoing neurosurgery often undergo peri-operative antibiotic prophylaxis, with different schedules, not always supported by scientific evidence. This consensus provides clear and shared indications, based on the most updated literature. This work has been made possible by the multidisciplinary contribution of experts belonging to the most important Italian scientific societies, and represents, in our opinion, the most complete and up-to-date collection of recommendations on the behavior to be held in the peri-operative setting in this type of intervention, in order to guide physicians in the management of the patient, standardize approaches and avoid abuse and misuse of antibiotics.

Abstract
INTRODUCTION Pyogenic ventriculitis is a severe infection of the central nervous system with serious and often irreversible consequences in the quality of life of patients. Its treatment is difficult due to the impossibility of achieving sterility of cerebrospinal fluid (CSF) and the physiological characteristics promptly. Several treatment options have been described, from prolonged antibiotic treatments to placement of ventricular drains with continuous irrigation and puncture reservoirs. We propose an aggressive and minimally invasive treatment with neuroendoscopic lavage (NEL). METHODS Retrospective and descriptive study. We analyzed the NEL performed in our hospital for pyogenic ventriculitis between 2011 and 2020. A total of 16 patients were found; 2 of them lost follow-up, so they were not included. All patients had a diagnosis of pyogenic ventriculitis, either due to the macroscopic characteristics of the CSF or due to imaging criteria. Between 1 and 3 NEL were performed per patient until obtaining sterility and normalization of protein and cell counts of CSF. RESULTS The average age was 38 months (2 months to 16 years). Ten patients were female and 4 were male. Sixty-four percent of germs in cultures corresponded to gram-negative and polymicrobial flora. The average number of days until the first sterile CSF post-NEL was 3.8 days (0 to 10 days). The NEL produced a significant improvement in the characteristics of the CSF compared to the pre-NEL. The mean pre-NEL of CSF protein levels was 907 mg/dl (123-4510 mg/dl) compared with the post-NEL of 292 mg/dl (38-892 mg/dl) with a p-value = 0.0076. Regarding cellularity, statistically significant results were also achieved (p-value = 0.0011) with a pre-surgical cellularity of 665 elements/mm3 (4-3090 elements/mm3) compared with 57 elements/mm3 (0-390 elements/mm3) post-NEL. Of the patients, 85.7% had a shunt prior to the onset of ventriculitis and the average number of days until the new shunt was 36.56 days (17-79 days), with a total hospitalization days ranging from 22 to 170. CONCLUSIONS NEL allows rapid sterilization of CSF, decreasing the deleterious effect of infection in the CNS more rapidly compared to other types of conventional treatment.

Abstract
The management of post-infective hydrocephalus in infants remains a challenging task for the pediatric neurosurgeon. The decision-making curve is often complex in that appropriate temporizing measures need to be implemented to properly clear any infection within the CSF before any decision can be made regarding a permanent solution. The etiology differs at varying stages of neonatal development, and the weight of the child, skin fragility, and relevant surgical treatment options are often important limiting factors. Deciding on the optimal treatment option involves assessing the etiology, age, and clinical and radiological features of the individual case and selecting the most appropriate surgical option.

Abstract
PURPOSE To assess the therapeutic efficacy of external ventricular draining (EVD) and to predict the need for permanent shunts in infants with postinfective hydrocephalus (PIHC). METHODS This is a retrospective study of infants diagnosed with PIHC and treated by EVD between January 2013 and December 2017 at the Children's Hospital of Fudan University. Clinical, laboratory, and imaging data were collected and analyzed to identify independent risk factors by logistic regression analyses. The predictor was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curves. RESULTS In total, 48 patients were identified, and 31 cases (64.5%) had a permanent shunt. EVD was effective in accelerating cerebrospinal fluid purification. In the permanent shunt group, the duration of EVD was significantly longer (28.5 ± 5.2 vs 14.9 ± 3.0 P < 0.05) and the frontal and occipital horn ratio (FOHR) at 7-10 days after EVD was significantly higher (0.57 ± 0.01 vs 0.48 ± 0.01 P < 0.001). The FOHR at 7-10 days after EVD predicts the need for a permanent shunt with an area under the ROC curve of 0.818. CONCLUSION EVD was effective for purification of CSF, whereas a permanent shunt was needed for more than half of the patients. The FOHR at 7-10 days after EVD may be a strong predictor for a permanent shunt.

Abstract
PURPOSE Neuroendoscopic procedures for treatment of term and preterm newborn infants, such as endoscopic lavage for posthemorrhagic hydrocephalus, are gaining popularity despite sparse data. This single-institution report compiles all neuroendoscopic surgical procedures performed in neonates during a 10-year period. METHODS Charts and electronic records were reviewed of all consecutive newborns who underwent a neuroendoscopic procedure before reaching a postmenstrual age of 44 weeks between 09/2010 and 09/2020. Available documentation was reviewed regarding the performed neuroendoscopic procedure, course of disease, complications, and all re-operations throughout the first year of life. RESULTS During the 10-year study period, 116 infants (median gestational age at birth: 29 1/7 weeks) underwent a total of 153 neuroendoscopic procedures (median postmenstrual age at surgery: 35 0/7 weeks). The most common indication at the time of the neuroendoscopic procedures (n = 153) was intraventricular hemorrhage (IVH, n = 119), intraventricular infection (n = 15), congenital malformation (n = 8), isolated 4th ventricle (n = 7), multiloculated hydrocephalus (n = 3), and tumor (n = 1). Thirty-eight of 116 children (32.8%) underwent 43 operative revisions after 153 neuroendoscopic procedure (28.1%). Observed complications requiring surgical revision were secondary infection (n = 11), CSF fistula (n = 9), shunt dysfunction (n = 8), failure of ETV (n = 6), among others. 72 children (62%) of 116 children required permanent CSF diversion via a shunt. The respective shunt rates per diagnosis were 47 of 80 (58.8%) for previously untreated IVH, 11 of 13 (84.6%) for intraventricular infection. Shunt survival rate for the first year of life was 74% for the whole cohort. CONCLUSION The experience with this large cohort of neonates demonstrates the feasibility of neuroendoscopic technique for the treatment of posthemorrhagic or postinfectious hydrocephalus. Rate and type of complications after neuroendoscopic procedures were within the expected range. Assessing the potential long-term benefits of neuroendoscopic techniques has to await results of ongoing studies.

Abstract
Most of childhood hydrocephalus are originating during infancy. It is considered to be a complex disease since it is developed on the basis of heterogeneous pathophysiological mechanisms and different pathological conditions as well as during different age groups. Hence, it is of relevant importance to have a practical concept in mind, how to categorize hydrocephalus to surgically better approach this disease. The current review should offer further basis of discussion on a disease still most frequently seen in Pediatric Neurosurgery. Current literature on pathophysiology and classification of pediatric hydrocephalus has been reviewed to integrate the different published concepts of hydrocephalus for pediatric neurosurgeons. The current understanding of infant and childhood hydrocephalus pathophysiology is summarized. A simplified concept based on seven factors of CSF dynamics is elaborated and discussed in the context of recent discussions. The seven factors such as pulsatility, CSF production, major CSF pathways, minor CSF pathways, CSF absorption, venous outflow, and respiration may have different relevance and may also overlap for the individual hydrocephalic condition. The surgical options available for pediatric neurosurgeons to approach hydrocephalus must be adapted to the individual condition. The heterogeneity of hydrocephalus causes mostly developing during infancy warrant a simplified overview and understanding for an everyday approach. The proposed guide may be a basis for further discussion and may serve for a more or less simple categorization to better approach hydrocephalus as a pathophysiological complex disease.

Abstract
INTRODUCTION Posthemorrhagic hydrocephalus in preterm infants is a serious entity related to high mortality and morbidity. Neuroendoscopic lavage (NEL) is a suitable alternative for the management of this pathology. However, as with every endoscopic technique, it requires some experience and several cases to master. METHODS We present a descriptive study of some technical nuances, tips, and tricks that have been learned in the last 8 years with over a hundred NELs performed in preterm infants. These variations are classified into 3 categories according to their temporal relationship with the surgical procedure: preoperative stage, intraoperative stage, and postoperative stage. We include a brief description of each one and the reasons why they are included in our current clinical practice. RESULTS Twenty tips and pearls were described in detail and are reported here. Preoperative, intraoperative, and postoperative variations were exposed and related to the most frequent complications of this procedure: infection, cerebrospinal fluid leak, and rebleeding. CONCLUSIONS NEL is a useful technique for the management of germinal matrix hemorrhage in preterm infants. These technical nuances have improved the results of our technique and helped us to prevent complications related to the procedure.

Abstract
OBJECTIVE Cerebral ventriculitis remains one of the most challenging neurosurgical conditions, with poor outcome and a long course of treatment and duration of hospital stay. Despite the current conventional management plans, i.e., using antibiotics in addition to CSF drainage, the outcome remains unsatisfactory in some cases, with no definitive therapeutic guidelines. This study aims to compare the outcome of ventricular irrigation/lavage (endoscopic irrigation or the double-drain technique) to conventional currently accepted therapy using just drainage and antibiotics. METHODS The authors conducted a prospective controlled study in 33 patients with cerebral ventriculitis in which most of the cases were complications of CSF shunt operations. Patients were divided into two groups. Removal of the ventricular catheter whenever present was performed in both groups. The first group was managed by ventricular lavage/irrigation, while the other group was managed using conventional therapy by inserting an external ventricular drain. Both systemic and intraventricular antibiotics were used in both groups. The outcomes were compared regarding mortality rate, modified Rankin Scale (mRS) score, and duration of hospital stay. RESULTS The mean age of the study population was 5.98 ± 7.02 years. The mean follow-up duration was 7.6 ± 3.2 months in the conventional group and 5.7 ± 3.4 months in the lavage group. The mortality rate was 25% (4/16) in the lavage group and 52.9% (9/17) in the nonlavage group (p = 0.1). The mRS score was less than 3 (good outcome) in 68.8% (11/16) of the lavage group cases and in 23.5% (4/17) of the conventional group (p < 0.05). The mean hospital stay duration was 20.5 ± 14.2 days in the lavage group, whereas it was 39.7 ± 16.9 days in the conventional group (p < 0.05). CONCLUSIONS Ventricular lavage or irrigation together with antibiotics is useful in the management of cerebral ventriculitis and associated with a better outcome and shorter hospital stay duration compared to current conventional lines of treatment.

Abstract
Intrathecal administration of anti-infectives is indicated in central nervous system infections by multiresistant pathogens when drugs that can reach adequate cerebrospinal fluid (CSF) concentrations by systemic therapy are not available. Antibiotics that readily pass the blood-brain and blood-CSF barriers and/or that have low toxicity allowing an increase in the daily dosage should not be used for intrathecal therapy. Intrathecal therapy is accompanied by systemic treatment. Antibacterials indispensable for intrathecal therapy include aminoglycosides, colistin, daptomycin, tigecycline, and vancomycin. Limited experience suggests the utility of the antifungals amphotericin B and caspofungin. Intraventricular administration ensures distribution throughout the CSF compartment, whereas intralumbar dosing often fails to attain adequate antibiotic concentrations in the ventricles. The individual dose is determined by the estimated size of the CSF space and by the estimated clearance from CSF. For moderately lipophilic anti-infectives with a molecular weight above approximately 1,000 g/mol, as well as for hydrophilic drugs with a molecular weight above approximately 400 g/mol, one daily dose is normally adequate. The ventricular drain should be clamped for 15 to 120 min to facilitate the distribution of the anti-infective in the CSF space. Therapeutic drug monitoring of the trough levels is necessary only in cases of therapeutic failure.

Abstract
BACKGROUND Ventriculitis, one of the difficulties in neurosurgical treatment, is a significant cause of death and morbidity in patients with hydrocephalus. Neuroendoscopy is widely used in the treatment of non-communicable hydrocephalus. The advantages of neuroendoscopy may play a decisive role in the treatment of ventriculitis. CASE REPORT AND METHODS We report a 34-year-old male patient with refractory fever and rapid progressive disturbance of consciousness due to ventriculitis caused by intraventricle rupture in a left colliculus abscess. He received intravenous (IV) antibiotics and saline neuroendoscopic lavage (NEL) combined with septostomy and endoscopic third ventriculostomy leading to rapid recovery and remission of symptoms. We also reviewed the use of NEL for ventriculitis in PubMed from 1970 to January 20, 2019. RESULTS In our review, 93 cases (including the present report) were treated with NEL; 91 cases of infection subsided, and 7 patients died. CONCLUSION NEL may be an effective method for the treatment of ventriculitis.

Abstract
PURPOSE Posthaemorrhagic ventricular dilatation in preterm infants is primarily treated using temporising measures, of which the placement of a ventricular access device (VAD) is one option. Permanent shunt dependency rates are high, though vary widely. In order to improve the treatment burden and lower shunt dependency rates, we implemented several changes over the years. One of these changes involves the setting of the surgery from general anaesthesia in the OR to local anaesthesia in bed at the neonatal intensive care unit (NICU), which may seem counterintuitive to many. In this article, we describe our surgical technique and present the results of this regimen and compare it to our previous techniques. METHODS Retrospective study of a consecutive series of 37 neonates with posthaemorrhagic ventricular dilatation (PHVD) treated using a VAD, with a cohort I (n = 13) treated from 2004 to 2008 under general anaesthesia in the OR, cohort II (n = 11) treated from 2009 to 2013 under general anaesthesia in the NICU and cohort III (n = 13) treated from December 2013 to December 2017 under local anaesthesia on the NICU. RESULTS The overall infection rate was 14%; the VAD revision rate was 22% and did not differ significantly between the cohorts. Procedures under local anaesthesia never required conversion to general anaesthesia and were well tolerated. After an average of 33 tapping days, 38% of the neonates received a permanent ventriculoperitoneal (VP) shunt. The permanent VP shunt rate was 9% with VAD placement under local anaesthesia and 52% when performed under general anaesthesia (p = 0.02). CONCLUSION Bedside placement of VADs for PHVD under local anaesthesia in neonates is a low-risk, well-tolerated procedure that results in at least equal results to surgery performed under general anaesthesia and/or performed in an OR.
