Abstract
PURPOSE The most frequent therapy of hydrocephalus is implantation of ventriculoperitoneal shunts for diverting cerebrospinal into the peritoneal cavity. We compared two adjustable valves, proGAV and proGAV 2.0, for complications resulting in revision surgery. METHODS Four hundred patients undergoing primary shunt implantation between 2014 and 2020 were analyzed for overall revision rate, 1-year revision rate, and revision-free survival observing patient age, sex, etiology of hydrocephalus, implantation site, prior diversion of cerebrospinal fluid, and cause of revision. RESULTS All data were available of all 400 patients (female/male 208/192). Overall, 99 patients underwent revision surgery after primary implantation. proGAV valve was implanted in 283 patients, and proGAV 2.0 valves were implanted in 117 patients. There was no significant difference between the two shunt valves concerning revision rate (p = 0.8069), 1-year revision rate (p = 0.9077), revision-free survival (p = 0.6921), and overall survival (p = 0.3232). Regarding 1-year revision rate, we observed no significant difference between the two shunt valves in pediatric patients (40.7% vs 27.6%; p = 0.2247). Revision operation had to be performed more frequently in pediatric patients (46.6% vs 24.8%; p = 0.0093) with a significant higher number of total revisions with proGAV than proGAV 2.0 (33 of 59 implanted shunts [55.9%] vs. 8 of 29 implanted shunts [27.6%]; p = 0.0110) most likely due to longer follow-up in the proGAV-group. For this reason, we clearly put emphasis on analyzing results regarding 1-year revision rate. CONCLUSION According to the target variables we analyzed, aside from lifetime revision rate in pediatric patients, there is no significant difference between the two shunt valves.

Abstract
Background Neurosurgical interventions in neonates may contribute to increased neonatal intensive care unit (NICU) stay. The impact of neurosurgical interventions on length of stay (LOS) and cost is not well-documented in the literature. In addition to LOS, other factors may impact overall resource utilization. Our objective was to perform a cost analysis of neonates who underwent neurosurgical procedures. Methods A retrospective chart review was performed on NICU patients who underwent ventriculoperitoneal and/or subgaleal shunt placement between January 1, 2010, and April 30, 2021. Postoperative outcomes were analyzed, including LOS, revisions, infections, emergency department (ED) visits following discharge, and readmissions accounting for health care utilization cost. Results Sixty-six neonates underwent shunt placement during our study period. Out of our 66 patients, 40% of infants had intraventricular hemorrhage (IVH). About 81% had hydrocephalus. Specific diagnoses for our patient population varied and included: 37.9% of patients had IVH complicated by posthemorrhagic hydrocephalus, 27.3% had Chiari II malformation, 9.1% had a cystic malformation leading to hydrocephalus, 7.5% had solely hydrocephalus or ventriculomegaly, 6.0% had myelomeningocele, 4.5% had Dandy-Walker malformation, 3.0% had aqueductal stenosis, and the remaining 4.5% had varying other pathologies. In our patient population, 11% of patients had an identified or suspected infection within 30 days after surgery. The average LOS was 59 days versus 67 days for patients with a postoperative infection. Number of patients who visited the ED within 30 days of discharge was 21%. Of these ED visits, 57% led to readmission. Complete cost analysis was available for 35 out of 66 patients. The average LOS was 63 days with average cost of admission of $209,703.43. Average cost for readmission was $25,757.02. Average daily cost for neurosurgical patients was $1,672.98 versus $1,298.17 for all NICU patients. Conclusion Neonates who underwent neurosurgical procedures had longer LOS as well as higher daily cost. LOS for infants with infections following procedures was increased by 10.6%. Further research is needed to optimize health-care utilization for these high-risk neonates.

Abstract
Objective This study was conducted to assess the outcome in patients with hydrocephalus who underwent ventriculoperitoneal (VP) shunt surgery. Methods This retrospective study was conducted at the neurosurgery department of a tertiary care hospital. The time frame was three years and five months from January 2017 to May 2020 with a follow-up of six months. Results This study included 1030 patients, out of whom 64.2% were male and 35.8% were female. While the majority of the patients were more than 11 years of age (466), age did not have any significant impact on the outcome of the ventriculoperitoneal shunt surgery. The most common cause of hydrocephalus was congenital (47.6%). A good outcome was seen in 63.4%, mortality was 10.6%, and complications were identified for 25.8%. The underlying pathology had a significant impact on the outcome in our study (p-value < 0.05) where the congenital cause of hydrocephalus showed a better outcome than any other cause. Conclusion Ventriculoperitoneal shunt is a good way to manage hydrocephalus, but there is always a high risk of complications.

Abstract
Introduction: COVID-19 patients frequently experience headaches, malaise, and fatigue. For patients with shunted hydrocephalus, these signs and symptoms can often be indicative of shunt failure. Thus, it can be challenging to determine if shunt failure has occurred in this patient population. Therefore, we explored the question of how a diagnosis of COVID-19 in shunted hydrocephalus patients influences the rate of shunt revision. Methods: We used a deidentified database network (TriNetX) to gather information on patients with shunted hydrocephalus and COVID-19 versus no COVID-19 from January 20, 2020, through September 26, 2021. Our primary outcome of interest was shunt revision at 90 days, with secondary outcomes of mortality, hospitalization, ICU admission, mechanical ventilation, tracheostomy, PEG tube placement, fall, seizure, acute kidney injury (AKI), venous thromboembolism (VTE), ischemic stroke (I.S.), myocardial infarction (MI), and sepsis. Cohorts were propensity score-matched for common comorbidities and demographics. Results: After propensity score matching, 10,600 patients with shunted hydrocephalus and COVID-19 (cohort 1) and 10,600 patients with shunted hydrocephalus and no COVID-19 (cohort 2) were identified. Average age was 38.5 years. Eight hundred and thirty-four patients (7.869%) in cohort 1 and 180 (1.698%) patients in cohort 2 underwent shunt revision (p=<0.0001, OR 4.978, 95% CI 4.198, 5.821). Mortality was 4.642% vs. 2.113% (p<0.0001, OR 2.255, 95% CI 1.921, 2.647). Hospitalization rates were 27.72% vs. 10.303% (p<0.0001), and ICU admission rates 11.567% vs. 3.463% (p<0.0001). Ventilator dependence was 3.529% vs. 0.953% (p<0.0001), tracheostomy 1.142% vs. 0.236% (p<0.0001), PEG tube insertion 2.472% vs. 0.585% (p<0.0001), falls 2.321% vs. 1.076% (p<0.0001), seizure 11.369% vs. 5.953% (p<0.0001), AKI 4.416% vs. 1.717% (p<0.0001), VTE 3.538% vs. 1.293% (p<0.0001), sepsis 3.887% vs. 1.179% (p<0.0001), IS 0.585% vs. 0.16% (p<0.0001), and MI 1.34% vs. 0.519% (p<0.0001). Conclusion: COVID-19 infection is associated with an almost five-fold increase in shunt revisions.

The effect of image-guided ventricular catheter placement on shunt failure: a systematic review and meta-analysis. Childs Nerv Syst 2022; 38:1069-1076. [PMID: 35501511 DOI: 10.1007/s00381-022-05547-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 04/26/2022] [Indexed: 01/08/2023]
Abstract
INTRODUCTION Cerebrospinal fluid (CSF) diversion for the treatment of hydrocephalus is one of the most common neurosurgical procedures. Over the years, the development of the neuronavigation system has allowed the surgeon to be guided in real time during the procedures. Nevertheless, to date, the revision rate remains as high as 30-40%. The aim of this study was to investigate the role of intraoperative image guidance in the prevention of shunt failure. We herein report the first literature meta-analysis of image guidance and shunt revision rate in the pediatric population. METHODS Principal online databases were searched for English-language articles published between January, 1980, and December, 2021. Analysis was limited to articles that included patients younger than 18 years of age at the time of primary V-P shunt. Articles reporting combined results of free-hand and image-guided placement of ventricular catheter (VC) were included. The main outcome measure of the study was the revision rate in relation to the intraoperative tools. Secondary variables collected were the age of the patient and ventricle size. Statistical analyses and meta-analysis plots were done via R and RStudio. Heterogeneity was formally assessed using Q, I2, and τ2 statistics. To examine publication bias was performed a funnel plot analysis. RESULT A total of 9 studies involving 2017 pediatric patients were included in the meta-analysis. 55.9% of procedures were carried out with the aid of intraoperative tools, while 44.1% procedures were conducted free hand. The intraoperative tools used were ultrasound (9.1%), electromagnetic neuronavigation (21.07%), endoscope (67.32%), and combined images (2.4%).The image-guided placement of VC was not statistically associated with a lower revision rate. The pooled OR was 0.97 [CI 95% 0.88-1.07] with an I2 statistics of 34%, t2 of 0.018 and a p-value of 0.15 at heterogeneity analysis. CONCLUSION Our analysis suggest images guidance during VC shunt placement does not statistically affect shunt survival. Nevertheless, intraoperative tools can support the surgeon especially in patients with difficult anatomy, slit ventricles or complex loculated hydrocephalus.

Abstract
A male infant with a history of ventriculoperitoneal (VP) implantation due to congenital hydrocephalus presented with fever and lethargy at the age of 8 month-old. Pericardial effusion was detected in transthoracic echocardiography, and he underwent pericardial window operation and was discharged in a stable condition. At 11 months of age, he presented again with fever, lethargy, recurrent vomiting, and respiratory distress. In both plain chest radiography and transthoracic echocardiography, VP shunt migration to the heart cavity was observed. The VP shunt had entered into the right ventricle after perforating the diaphragm and pericardium. The patient underwent open-heart surgery due to vegetation at the tip of the VP shunt inside the right heart. Vegetation was removed and the tip of the shunt was returned to the peritoneal cavity. Two weeks after discharge, the patient presented again with symptoms of tachypnea and lethargy. The imaging revealed the entry of the VP shunt about two centimeters into the anterior mediastinum. The patient was transferred to the operation room and the VP shunt was shortened and re-inserted into the peritoneal cavity. Antibiotic treatment was continued for six weeks and the patient was discharged in stable condition. In follow-up visits after two years, the VP shunt functioned well and no particular complication was observed. This case demonstrates that in patients with VP shunt implantation presenting with pulmonary and cardiac symptoms such as respiratory distress, pericardial effusion, and cardiac tamponade after VP shunt implantation, the possibility of VP shunt catheter migration to the mediastinal cavity should be considered.

Abstract
BACKGROUND Despite advances in hydrocephalus shunt technology and improvement in hydrocephalus management, many patients have chronic disability and require multiple surgeries throughout their lifetime. There is limited data from patients' perspective regarding the impact of shunt devices on quality-of-life. METHODS A cross-sectional survey was developed to evaluate the impact of shunt devices on patient quality-of-life. The survey was distributed via social media platforms of the Hydrocephalus Association, and patients self-selected to anonymously complete the online questionnaire. A literature review was performed to contextualize the findings from the survey. RESULTS A total of 562 survey responses were obtained from a network encompassing 35,000 members. The mean age was 30 years old (0.5-87), and 65% identified as female. Eighty one percent underwent at least 1 shunt revision surgery, with a reported average of 10 shunt revision surgeries per patient (1-200 surgeries). Occlusion, shunt migration and infection were the leading causes for revision at 60%, 47%, and 35%, respectively. In addition, 72% of patients reported pain and discomfort from the device, and 68% expressed avoidance of certain activities due to "fear of bumping shunt." Despite numerous articles discussing shunt technology, a review of the literature indicated a paucity of studies specifically evaluating the burden of shunt devices from a patient/caregiver perspective. CONCLUSIONS The findings from this study suggest long-term physical and psychosocial burden associated with shunt devices. Importantly, this study highlights the need for concerted efforts to develop validated tools to study patient reported outcomes as it relates to neurocranial implanted devices.

Abstract
INTRODUCTION Currently, the most effective treatment strategy for adults with hydrocephalus involves cerebrospinal fluid diversion by means of a shunt system, most commonly ventriculoperitoneal shunts (VPS). Ventriculoperitoneal shunting is associated with high complication and/or revision rates, in part due to the high-profile programmable valve designs. Thus, the valve-agnostic cranial implant (VACI) was designed and investigated as a safe and effective method of reducing the valve's high profile and is currently undergoing clinical trials. As such, the objective of this study was to collate preliminary, multi-institutional data of early outcomes using a VACI approach for patients requiring VPS by way of an Institutional Review Board approved registry. METHODS A total of 25 adult patients across 4 institutions and 6 surgeons underwent VACI placement for VPS based on preoperative evaluation and perceived benefit. Patient demographics, operative details, and preliminary outcomes are presented here. RESULTS Valve-agnostic cranial implant placement via a limited size craniectomy at time of shunt revision was performed with no adverse events. Over an average follow-up period of 1 year (394 ± 178 days), 92% of patients experienced no major shunt-related or scalp-related complications. There were 2 cases with a major complication requiring reoperation: 1 shunt tubing extrusion and 1 case of meningitis. The most frequent postsurgical intervention seen in this study was related to adjustment of drainage: a non-invasively performed valve reprogramming after initial shunt placement when proper flow rate is being established. Of the 8 cases of drainage adjustment, all but 1 (88%) were receiving a VPS for the first time, with the exception undergoing a fourth shunt revision. All instances of improper flow were treated non-surgically and remediated effectively via shunt reprogramming in clinic. Removal of the VACI was not indicated in any treatment course. In this way, all complications as they relate to the shunt valve were minor and required nonsurgical intervention, and no complications reported were directly or indirectly caused by using the VACI. CONCLUSION Preliminary findings from this multicenter trial suggest promising outcomes with a low complication rate for patients with hydrocephalus undergoing VACI placement during VPS. Ongoing research will continue to provide a more robust clinical picture of VACI in hydrocephalus management as more data becomes available.

Abstract
Ventriculoperitoneal shunt catheter migration is a rare but documented complication. The exact mechanism of this occurrence is not well understood. We report the case of an 81-year-old male who initially presented with symptoms consistent with normal pressure hydrocephalus. A ventriculoperitoneal shunt was placed uneventfully. Four months later, the patient presented complaining of a persistent headache despite multiple adjustments in the shunt setting. Shunt series radiographs demonstrated the distal catheter passing through the superior vena cava and looping into the right cardiac atrium and ventricle. Catheter retrieval was attempted from a proximal retroauricular incision but required a combination of snare technique by interventional radiology and, ultimately, surgical venotomy by a cardiothoracic surgeon. The distal catheter was replaced in the abdomen, and the patient had no further complications. This case is the first of its kind reported in the literature that includes a treatment team comprising neurosurgery, interventional radiology, and cardiothoracic surgery. We highlight the importance of a multidisciplinary approach to best address the migrated catheter.
