Abstract
BACKGROUND Chronic hydrocephalus in adults (CHiA) includes all nonacute forms of hydrocephalus occurring in adulthood. It covers a spectrum of disorders. Some of these have relatively agreed on definitions, while others are less well characterized. The existing medical classification systems lack adequate structure and are neither clinically oriented nor easy to use, which severely hampers research and clinical care efforts. METHODS A systematic literature review and data analysis were performed, focusing on the terms "adult hydrocephalus" and "classification," using the PubMed, Scopus, and Cochrane Library databases. Data on terminology, definitions, patient demographics, symptom duration, and clinical presentations were extracted, analyzed, and compiled. A Delphi process was followed to define CHiA disorders. RESULTS A total of 33 studies collectively used 48 terms to define various CHiA disorders. Different terms were used to describe similar conditions. CHiA disorders were found to be clustered into 7 distinctive clinical entities based on the clinical characteristics. CONCLUSIONS An evidence-based new clinical classification for CHiA is suggested. Our review identified gaps in knowledge and areas for further research.

Clinical and surgical outcome of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) in patients with Long-Standing Overt Ventriculomegaly in Adults (LOVA): a systematic review. Neurol Res 2024; 46:81-88. [PMID: 37722694 DOI: 10.1080/01616412.2023.2257461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 07/19/2023] [Indexed: 09/20/2023]
Abstract
OBJECTIVES The optimal surgical procedure for long-standing overt ventriculomegaly in adults (LOVA) remains controversial. METHODS A systematic search of three databases was performed for studies published between January 1999 and March 2022. This systematic review included 12 studies with a total of 318 patients with LOVA surgically treated. PRISMA guidelines were followed. RESULTS Gait disturbance (74.8%) and headache (59.7%) were the most common clinical presentation. Overall, the rate of postoperative clinical improvement at the last follow-up was 83.6% (95% CI 78.1-86.1). A lower rate of postoperative clinical improvement or halt of progression of presenting symptoms was observed after ETV (211/257 = 82.1% 95% CI 76.2-85.1%) compared with VPS (55/61 = 90.2% 95% CI 80.3-96.1%). Overall, surgical and postoperative complications were reported in 22/297 patients (7.5% 95% CI 4.4-20%) (11 studies). A higher rate of surgical complications was observed in patients treated with VPS (19.7% 95 CI 5.9-46.7%), compared with patients treated with ETV (4.3% 95% CI 2.1-10.9%). The overall rate of second surgery due to failure of first surgical approach (ETV or VPS) was 46/275 (16.7%). DISCUSSION This meta-analysis confirmed the efficacy of EVT and VPS in symptomatic patients with LOVA, reporting a roughly 84% of postoperative clinical improvement or halt of progression of symptoms. A higher rate of surgical complications was observed in patients treated with VPS compared with patients treated with ETV. In addition, roughly 18% of patients treated with ETV required a further VPS. These findings should be considered when advising LOVA patients regarding the management of hydrocephalus.

Abstract
BACKGROUND Long-standing overt ventriculomegaly in adults (LOVA) is a heterogeneous term describing forms of adult hydrocephalus. LOVA incidence is increasing, yet the optimal treatment strategy for symptomatic cases remains unclear. We compared success rates and complication rates between endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) as first-line treatment for LOVA. METHODS A systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. Three databases were searched, and articles published from 2000 to October 2022 were included (last search date October 24, 2022). Success rates and complications of both ETV and VPS were compared using random-effects models. RESULTS Of 895 articles identified, 22 studies were included in the analysis (556 patients: 346 in ETV group, 210 in VPS group). Mean age was 44.8 years. The most common presenting symptoms were gait disturbance (n = 178), headache (n = 156), and cognitive decline (n = 134). Combined success rates were 81.8% (n = 283/346) in the ETV group and 86.7% (n = 182/210) in the VPS group (median follow-up 41 months). There was no difference in success rates between ETV and VPS groups (odds ratio 0.94, 95% confidence interval 0.86-1.03, I2 = 0%). Combined complication rates were 4.6% (n = 16/346) in the ETV group and 27.1% (n = 57/210) in the VPS group. ETV had a lower rate of postoperative complications (odds ratio 0.22, 95% confidence interval 0.11-0.33, I2 = 0%). CONCLUSIONS Symptomatic LOVA can be successfully managed with surgical intervention. ETV and VPS have similar success rates when used as first-line treatment. VPS has a higher complication rate.

Abstract
BACKGROUND Longstanding overt ventriculomegaly in adults (LOVA) is a new form of progressive hydrocephalus characterized by onset in early childhood and gradual progression into adulthood. Patients with LOVA are usually asymptomatic in childhood. The diagnosis of LOVA in adolescence has not been reported. CASE REPORT A patient with macrocephaly and mild ventriculomegaly from infancy developed headache exacerbation and cognitive dysfunction at the age of 11 years. Brain magnetic resonance imaging showed mild tri-ventriculomegaly with no radiological aggravation compared to imaging at the age of 8 years. No papilledema was observed. Drainage of 15 ml of spinal fluid via a lumbar puncture relieved the headache and cognitive dysfunction. Based on repeated improvements in cognitive function and headaches after spinal fluid drainage, we diagnosed the patient with LOVA with symptom onset in early adolescence. A ventriculoperitoneal shunt was placed, and the headaches disappeared completely. The full-scale intellectual quotient, verbal comprehension, and working memory improved significantly. CONCLUSIONS LOVA may manifest as early as adolescence. The clinical presentation, age, clinical, radiological features, and management vary, and a spinal tap exam is useful for diagnosing LOVA, even in children. The spinal tap exam may be indicated in children with longstanding ventriculomegaly and deteriorating neurological symptoms to diagnose this "treatable intellectual disability."

Abstract
OBJECTIVE It is difficult to demonstrate the success of the procedure in patients with third ventriculostomy. We evaluated that optic nerve sheath diameter (ONSD) measurement, which can reflect intracranial pressure, may be a criterion for decision of endoscopic third ventriculostomy (ETV) success. METHODS 28 adult patients suffering long overt standing ventriculomegaly (LOVA) who performed ETV were included in this retrospective study. The patients were divided into two groups as successful (group A) and failed ETV group (group B) according to their postoperative evaluation. ONSD was measured on pre- and post-operative computed tomography (CT) and Evan's index (EI), diameter of third ventricule (V3), the patency of ETV stoma and periventricular edema were evaluated by magnetic resonance imaging (MRI). RESULTS The mean ONSD was measured as 6.39±0.92mm for the right eye, 6.50±0.91mm for the left eye on preoperative CT. The mean ONSD by CT (after surgery) was 4.89±0.87mm for the right eye, 5.02±0.1mm for the left eye (p<0.05). Postoperative group A and group B were compared according to ONSD measurement; mean ONSD in group A was 4.52±0.69mm for the right and 4.59±0.9mm for the left, mean ONSD in group B was 5.82±0.51mm for the right and 6.1±0.32mm for the left (p<0.05). The best ONSD value for detecting failed ETV was 5.40mm (sensitivity 90%, specifity 75%, AUROC 0.938) for right and 5.91mm (sensitivity 90%, specifity 75%, AUROC 0.950) for left. EE was measured as 0.39±0.12mm on preoperative MRI and 0.39±0.12mm on postoperative MRI (p=0.3). V3 was measured as 14.7±2.47mm on preoperative MRI and 10.47±1.99mm on postoperative MRI (p<0.05). CONCLUSION The statistical values obtained from study show that the ONSD measurement can help in the postoperative evaluation of patients, who had a ETV surgery.

Abstract
ObjectiveThe aim of the present study is to evaluate a neurocognitive outcome in patients affected by late-onset idiopathic aqueductal stenosis (LIAS) who underwent endoscopic third ventriculostomy (ETV).Materials and MethodsA prospective study was conducted between January 2015 and December 2017 in a series of 10 consecutive adult patients referred to the Neurosurgery Department of IRCCS Istituto delle Scienze Neurologiche di Bologna, Bologna, Italy. All the adult patients admitted with absence of CSF flow through the aqueduct in phase-contrast (PC)—MRI sequences or a turbulence void signal in T2—weighted images in midsagittal thin-slice MR sequences underwent a specific neuroradiological, neurological, and neurocognitive assessment pre- and postoperatively.ResultsAll patients affected by gait and sphincter disturbances improved after ETV. Attentive and executive functions as well as visuo-spatial memory and verbal executive functions improved in several patients. Similarly, the affective and behavioral scales improved in almost 50% of the patients. No major complications have been recorded, and no patients required a second surgery for shunt placement.ConclusionEndoscopic third ventriculostomy represents a safe and effective surgical procedure for the treatment of LIAS. In addition to neurological improvement, we demonstrated also postoperative neurocognitive improvement mainly in attentive and executive functions, visuo-spatial memory, verbal executive functions, and behavioral and affective domains.

Surgical Treatment of Long-Standing Overt Ventriculomegaly in Adults (LOVA): A Comparative Case Series between Ventriculoperitoneal Shunt (VPS) and Endoscopic Third Ventriculostomy (ETV). INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19041926. [PMID: 35206112 PMCID: PMC8872207 DOI: 10.3390/ijerph19041926] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 02/04/2022] [Accepted: 02/06/2022] [Indexed: 02/01/2023]
Abstract
Background: Long-standing overt ventriculomegaly in adults (LOVA) is an uncommon type of adult chronic hydrocephalus. In recent years, conflicting case series described different outcomes after treatment of LOVA with endoscopic third ventriculostomy (ETV) or ventriculoperitoneal shunt (VPS). The aim of this study is to report a single institutional surgical experience of patients with LOVA in order to evaluate the clinical outcome of those patients treated with one or, sometimes, both surgical procedures, analyzing the main clinical features of these patients, before and after surgery. Methods: We conducted a retrospective study on 31 patients with diagnosis of LOVA, who were treated in our University Hospital between December 2010 and October 2020. We reported gender, age, clinical presentation, surgical treatment, and clinical outcome according to the Kiefer index (KI). Evans’ index, head circumference, aqueductal stenosis and expanded/destroyed sella turcica were assessed on preoperative MRI. Results: The most common clinical manifestation was gait disturbances (100%) followed by urinary incontinence in 23 (74.2%) patients and cognitive deficits in 22 (71%) patients. On preoperative MRI, the overall mean Evans’s Index was 0.49, whereas the overall mean head circumference was 57.3 cm. Twenty-three patients (74.2%) had obliterated cortical sulci, 20 (64.5%) patients had aqueductal stenosis, and 22 (71%) patients had an expanded/destroyed sella turcica on preoperative MRI. Fifteen (48.4%) patients underwent ETV and sixteen (51.6%) were treated with VPS as first surgical procedure. Four (26.6%) out of fifteen patients treated with ETV required a subsequent VPS. The overall median age of patients was 64 (IQR: 54.5–74) and the overall median follow-up was 57 months (IQR 21.5–81.5). Overall morbidity was 22.5%. Mean recovery index (RI), according to KI, was 3.8 ± 4.3 and 2.2 ± 5.6 (p = 0.05) at last follow-up in patients treated with ETV and VPS, respectively. Conclusions: The choice of surgical treatment of LOVA remains under discussion. Although EVT is a tempting option for patients with LOVA, conversion to VP shunt is not uncommon.

A retrospective cohort study. Neurosurg Rev 2022; 45:3193-3200. [PMID: 35688957 PMCID: PMC9492616 DOI: 10.1007/s10143-022-01812-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 04/16/2022] [Accepted: 05/10/2022] [Indexed: 02/03/2023]
Abstract
Long-standing overt ventriculomegaly in adults (LOVA) is a heterogenous group of conditions with differing presentations. Few studies have evaluated success rates of available surgical treatments, or ascertained the natural history. There is a need to assess the efficacy of both endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) as first-line treatments. We conducted a retrospective, single-centre study of adults with LOVA at a tertiary neurosurgery centre in England, UK, aiming to identify presentation, management strategy, and outcome following treatment. A total of 127 patients were included (mean age 48.1 years, 61/127 male). Most patients were symptomatic (73.2%, n = 93/127, median symptom duration 10 months). The most common symptoms were gait ataxia, headache, and cognitive decline (52.8%, 50.4%, and 33.9%, respectively). Fourteen patients had papilloedema. Ninety-one patients (71.7%) underwent surgery (84 ETV, 7 VPS). Over a median follow-up of 33.0 months (interquartile range [IQR] 19.0-65.7), 82.4% had a clinical improvement after surgery, and 81.3% had radiological improvement. Clinical improvement rates were similar between ETV and VP shunt groups (82.1% vs 85.7%, p = 0.812). Surgical complication rates were significantly lower in the ETV group than the VP shunt group (4.8% vs 42.9%, p < 0.001). Of the patients treated surgically, 20 (22.0%) underwent further surgery, with 14 patients improving. This study demonstrates the efficacy of ETV as a first-line treatment for LOVA.

Abstract
RATIONALE Hydrocephalus is a common disease in neurosurgery. The typical symptoms of hydrocephalus include urinary incontinence, gait instability, and cognitive decline. Irritability rarely occurs in patients with hydrocephalus. Irritability rarely occurs in patients with hydrocephalus, especially in long-standing overt ventriculomegaly of adulthood (LOVA). PATIENT CONCERNS A 30-year-old female was admitted to our hospital because of mental retardation and unstable gait for more than 15 years. She had undergone ventriculoperitoneal shunt 15 years prior due to ventriculomegaly and related symptoms. However, the shunt catheter was removed shortly after surgery because of blockage, with no further postoperative treatment. DIAGNOSIS The patient was diagnosed with long-standing overt ventriculomegaly according to her head circumference and clinical symptoms, including adult hydrocephalus development, overt triventriculomegaly and absence of a secondary cause for aqueductal stenosis in adulthood. INTERVENTIONS After considerable discussion, she underwent ventriculoperitoneal shunt placement and showed dramatic and sustained improvement. OUTCOMES The patient has been followed at 3-month intervals for over 2 years since discharge, and both the patient and family have reported a significant change in their daily life. She was able to live independently and control her emotions. Slight epilepsy was noted approximately 5 months after surgery but recovered 2 months later. LESSONS It is difficult to decide whether to treat LOVA when the in patients whose symptoms are not significant. We believe that early diagnosis and positive treatment can help improve outcomes and would recommend ventriculoperitoneal (VP) shunting in patients with LOVA.

Abstract
Purpose Longstanding overt ventriculomegaly in adults (LOVA) represents a form of chronic adulthood hydrocephalus with symptomatic manifestation in late adulthood. Based on the patency of the aqueduct, two different subcohorts of LOVA can be distinguished. Surgical treatments of this condition are also debated. Therefore, we analyzed preoperative characteristics and clinical outcome after different surgical treatments in a subgroup of LOVA patients with a patent aqueduct. Methods Eighteen LOVA patients with a patent aqueduct consecutively treated at our institution between July 2013 and December 2019 were analyzed for this study. Median age was 70 years. Preoperative radiological and clinical features, surgical procedures (ventriculo-peritoneal shunt or endoscopic third ventriculostomy), and outcomes were collected. Successful outcome was qualitatively defined as an improvement or a halt of progression of the presenting symptoms at follow-up, and quantitatively by changes in mRS and iNPHGS scales. Results Twelve patients underwent an ETV as a primary treatment, while 6 underwent VPS. A total of 22.2% of them were lost to follow-up. Median follow-up time was 38 months. Six patients (66.7%) in the ETV cohort achieved a successful outcome after treatment, with a complication rate of 11.1%. Two patients underwent rescue VPS after ETV failure with a good outcome. Four patients (100%) underwent primary VPS and achieved a satisfactory outcome after treatment, with a reported complications rate of 25%. Conclusion LOVA with patent aqueduct represents, in our opinion, a distinct clinical form of chronic hydrocephalus. For this subgroup, as well as for other forms of LOVA, ETV remains an acceptable first-line treatment option considering the good results, and the low complication rate, obtained in those patients and the hypothesis that hydrocephalus is due to an “intracisternal” obstruction.

Long-Standing Overt Ventriculomegaly in Adults (LOVA): Diagnostic Aspects, CSF Dynamics with Lumbar Infusion Test and Treatment Options in a Consecutive Series with Long-Term Follow-Up. World Neurosurg 2021; 156:e30-e40. [PMID: 34425295 DOI: 10.1016/j.wneu.2021.08.068] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 08/12/2021] [Accepted: 08/13/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Long-standing overt ventriculomegaly in adults is a chronic form of hydrocephalus without a clear pathophysiological description and a consensus about the treatment. We present the results of endoscopic third ventriculostomy (ETV) in a consecutive series with a mean follow-up of 79 ± 23 months, highlighting how the preoperative lumbar infusion test could facilitate understanding the pathophysiology of the disease. METHODS We retrospectively collected data regarding clinical assessment, neuroradiological findings, and preoperative lumbar infusion tests in 22 symptomatic patients. RESULTS In the majority of cases, patients reported imbalance and gait disorders, and 8 subjects had headaches. The preoperative lumbar infusion test demonstrated a mean opening pressure of 13.95 ± 2.88 mm Hg, with plateau values ranging from 22 to 39 mm Hg. The resistance to outflow was 11.21 ± 2.00 mm Hg/mL/min. After the procedure, all patients reported improvement or halted progression in their presenting symptoms, whereas no significant reduction was demonstrated in Evans' index. One subject underwent a second ETV procedure after more than 2 years because of the failure of the endoscopic approach. CONCLUSIONS A progressive exhaustion of brain compliance plays an important role in explaining the dichotomy between severe ventriculomegaly and mild clinical symptoms in patients with long-standing overt ventriculomegaly in adults. The role of the aqueductal stenosis as a diagnostic criterion might be reconsidered. The preoperative infusion test data support this observation. Preoperative assessment should include not only clinical and neuroradiological evaluation but also the study of cerebrospinal fluid dynamics. ETV should be considered the treatment of choice because of its safety and efficacy. Long-term follow-up is mandatory.

Abstract
OBJECTIVE It is difficult to demonstrate the success of the procedure in patients with third ventriculostomy. We evaluated that optic nerve sheath diameter (ONSD) measurement, which can reflect intracranial pressure, may be a criterion for decision of endoscopic third ventriculostomy (ETV) success. METHODS 28 adult patients suffering long overt standing ventriculomegaly (LOVA) who performed ETV were included in this retrospective study. The patients were divided into two groups as successful (group A) and failed ETV group (group B) according to their postoperative evaluation. ONSD was measured on pre- and post-operative computed tomography (CT) and Evan's index (EI), diameter of third ventricule (V3), the patency of ETV stoma and periventricular edema were evaluated by magnetic resonance imaging (MRI). RESULTS The mean ONSD was measured as 6.39±0.92mm for the right eye, 6.50±0.91mm for the left eye on preoperative CT. The mean ONSD by CT (after surgery) was 4.89±0.87mm for the right eye, 5.02±0.1mm for the left eye (p<0.05). Postoperative group A and group B were compared according to ONSD measurement; mean ONSD in group A was 4.52±0.69mm for the right and 4.59±0.9mm for the left, mean ONSD in group B was 5.82±0.51mm for the right and 6.1±0.32mm for the left (p<0.05). The best ONSD value for detecting failed ETV was 5.40mm (sensitivity 90%, specifity 75%, AUROC 0.938) for right and 5.91mm (sensitivity 90%, specifity 75%, AUROC 0.950) for left. EE was measured as 0.39±0.12mm on preoperative MRI and 0.39±0.12mm on postoperative MRI (p=0.3). V3 was measured as 14.7±2.47mm on preoperative MRI and 10.47±1.99mm on postoperative MRI (p<0.05). CONCLUSION The statistical values obtained from study show that the ONSD measurement can help in the postoperative evaluation of patients, who had a ETV surgery.

Abstract
OBJECTIVE Long-standing overt ventriculomegaly in adults (LOVA) is form of hydrocephalus that develops during childhood, manifesting its symptoms during adulthood. Only a small number of LOVA case series have been published, and controversies regarding optimal management still exist. The authors collected a series of symptomatic LOVA patients treated successfully using endoscopic third ventriculostomy (ETV), aiming to strengthen what has been reported in the literature on ETV's role in both neurologic and neurocognitive outcomes. METHODS Between 2002 and 2020, we collected 40 case studies of patients treated using an ETV. Associated pathologies were documented in 14 cases. All patients underwent magnetic resonance scans preoperatively and postoperatively while only 29 patients were submitted during follow-up to neurocognitive assessment. RESULT At a mean follow-up of 6 years, 36 patients (90%) reported either an improvement or a stabilization of their presenting symptoms. Headache improved subjectively in 11 patients (27.5%), balance and gait disturbances improved in all patients, urinary incontinence improved in 24 patients (60%), memory disturbances subjectively improved in 21 patients (52.5%), and visual deficits improved in 5 patients (12.5%). Four patients (10%) had symptom progression, which occurred 6 to 24 months after surgery with radiologic evidence of ETV failure. CONCLUSIONS LOVA is a form of hydrocephalus that must be correctly identified. A correct magnetic resonance study and comprehensive neuropsychologic assessment are crucial to identify it in order to define proper management. From our analysis, ETV represents the gold standard treatment granting rewarding results that are maintained in a long-term follow-up.

Abstract
BACKGROUND Endoscopic third ventriculostomy is an established treatment for noncommunicating hydrocephalus. In carefully selected patients, it can be adopted for the management of communicating variant; however controversy exists in regards to the definition of the appropriate candidates. Predictive score of Endoscopic Third Ventriculostomy Success (ETVSS) has been reported for pediatric and mixed populations only. Our purpose was to define a ETV success score for adult population (ETVSS-A), measuring the strength of correlation between preoperative score retrospectively evaluated and the success rates achieved in a class of adult patients. METHODS A retrospective analysis of 47 cases which received ETV procedure at our Institution between 2015 and 2018 was run. Demographic data,clinical history,preoperative and postoperative signs were reviewed and ETVSS-A was calculated. Thereafter ETVSS-A results were compared with the actual success rates. RESULTS 29 patients(61,7%) presented unchanged or improvedclinical status with a mean ETVSS-A of 54.5%;18 patients(38,3%) worsened with mean ETVSS-A of 37,7%. We found that age,type of hydrocephalus and symptoms of admission are each apart important factors in predicting ETV success:older patients and those with non-obstructive hydrocephalus had the lowest predicted ETV success. In patients in whom ETV was actually successful, the pre-operative ETVSS-A was significantly higher as compared to those patients in whom we observed a poor surgical outcome. CONCLUSIONS From the results of this series, though small and retrospectively analyzed, it seems that ETVSS-A can be considered as a useful instrument to help neurosurgeon in predicting the ETV success and though define a more accurate surgical strategy in cases of hydrocephalus. Wider series and prospective studies are attended to validate these preliminary results.

Abstract
Objectives: The aim of this study is to define the role and effectiveness for an endoscopic third ventriculostomy (ETV) in patients with seconder normal pressure hydrocephalus(SNPH), idiopathic normal pressure hydrocephalus (INPH) and symptomatic longstanding overt ventriculomegaly (SLOVA). Materials and Methods: 3 patients with SLOVA, 3 patients with INPH and 3 patients with SNPH underwent ETV were studied retrospectively. The patients had a follow-up of 1-6 years. Preoperative CT or/and MRI of the brain was done in all cases. Tap test was done in all cases. Clinical examination finding were classified according to the by Japanese Committee for Scientific Research (JCSS) on intractable Hydrocephalus. Patients were studied to evaluate of the patency of ventriculosthomy and aqueduclus slyvius by a Cine PC MR and CSF_DRİVE T2 Sequence MRI after 1-6 years. Results: Headache, gait disturbance and pollakiuria improved in three patients with SNPH underwent ETV, but dementia didn’t improve in one patient. Pollakiuria and headache improved in three patients with INPH underwent ETV but preoperative gait disturbance grade three remained unchanged in one patient. Headache improved in three patients with SLOVA underwent ETV. Preoperative gait disturbance grade 3 remained unchanged in one patient, but improved pollakiuria. We confirmed the patency of a third ventriculostomy and decreasing degrees of CSF flow into the aquaductus sylvius. Conclusions: In properly selected patients with SNPH, SLOVA and INPH who had headache, slight gait disturbance and pollakiuria, mainly those with a short duration of symptoms, ETV may provide good results.

Abstract
BACKGROUND Longstanding overt ventriculomegaly in adults (LOVA) is characterised by chronic hydrocephalus presumed to begin during infancy, but arresting before becoming clinically detectable. Later in life clinical features of hydrocephalus ensue, typically in the 5th or 6th decades. Only a relatively small number of LOVA case series have been published, and ambiguity remains regarding optimal management. This case series describes a series of patients with LOVA treated successfully at a single neurosurgical institution using endoscopic third ventriculostomy (ETV). METHODS A series of 14 patients were diagnosed with LOVA using established clinical and radiological criteria. All patients underwent an ETV and their clinical conditions were followed up for up to 5 years post-operatively. RESULTS Fourteen patients (100 %) reported either improvement or halt of progression in their presenting symptoms 3 months after ETV; 93 % of patients (n = 13) did not require any further surgical intervention. One patient (7 %) reported deterioration in symptoms beyond 3 months post-operatively, which necessitated further surgery (ventriculoperitoneal shunt). These promising outcomes after ETV are mirrored in numerous other LOVA case series. Other works have analysed the value of CSF shunting procedures in LOVA, with mixed results. A direct, prospective comparison of outcomes after shunt procedures and ETV, with a specific focus on LOVA patients, is yet to be completed. A minority of patients fail to respond, or develop recurrence of symptoms, months or years after initial surgical intervention. CONCLUSIONS ETV is an attractive option for surgical treatment of LOVA. After surgical treatment for LOVA, long-term follow-up should be considered to screen for late recurrence of the condition.

Abstract
BACKGROUND The neuropsychological effects of lumbar puncture and shunting in terms of cognitive functioning and quality of life were analyzed prospectively in four patients with malabsorptive hydrocephalus who became symptomatic in the chronic state after aneurysmal subarachnoid haemorrhage (SAH). METHODS A comprehensive battery of neuropsychological tests was applied to four patients before and shortly after lumbar puncture and six months later. In three of them a shunt has been inserted, one patient was treated by repeated lumbar punctures. In addition, the patients completed a quality of life and a depression questionnaire before lumbar puncture and after shunting. The data were analyzed using single-case methodology. RESULTS Hydrocephalus was associated with pronounced cognitive deficits in terms of functions of attention, short- and long-term memory, concentration and motor fine-coordination but not with a general mental deterioration. Quality of life and affect were also substantially impaired. Neuropsychological tests of fronto-cortical cognitive capacity, motor fine coordination and reaction time proved to be sensitive for the short-term effects of lumbar puncture. Memory functions and the capacity of divided attention needed more time for regeneration and improved substantially after shunt implantation. CONCLUSIONS We found a complex pattern of cognitive improvement after lumbar puncture and shunting. Furthermore, our results also show a typical cluster of cognitive deficits associated with malabsorptive hydrocephalus including motor dysfunction. These preliminary findings should be confirmed in larger patient samples.

Abstract
OBJECTIVE Arrested hydrocephalus is stable ventriculomegaly without evidence of neurologic deterioration or symptoms. Management of arrested hydrocephalus in asymptomatic adults is controversial, with little clinical data. This case highlights the potential for decompensation in adults with arrested hydrocephalus and reviews the literature regarding pathophysiology and management of this clinical entity. PATIENTS AND METHODS A 39 year-old gentleman with arrested hydrocephalus incidentally found during work-up for new-onset seizure and managed conservatively for ten years presented with increasing headache, memory loss, gait instability and urinary and fecal incontinence. Stable massive triventriculomegaly was documented on serial brain imaging, and ophthalmologic exam revealed no papilledema. RESULTS The patient underwent endoscopic third ventriculostomy with immediate post-operative improvement of headache, resolution of incontinence, and cessation of seizures. At 15 months after surgery, neuropsychiatric testing demonstrated improvement in visuomotor skills, problem solving, verbal fluency and cognitive flexibility compared to his pre-operative baseline. At 18 months after surgery he remained seizure free with full continence and significant improvement in headaches. CONCLUSION Early recognition of arrested hydrocephalus and its potential for decompensation may prompt surgical treatment and prevent neurologic deterioration.

Abstract
BACKGROUND Shunts are generally associated with a smaller post-treatment ventricular size in comparison to endoscopic third ventriculostomy (ETV). METHODS To determine whether such a difference in ventricular size has neurocognitive implications, we reviewed the current literature pertaining to the (1) neurocognitive sequelae of hydrocephalus, (2) neurocognitive outcome after ETV, (3) extent of reversal of neurocognitive changes associated with hydrocephalus after shunting, and (4) data on correlation between post-treatment ventricular volume and neurocognitive outcome after ETV. RESULTS Collectively, the results of the available studies should call into question the correlation between the residual postoperative ventricular volume and neurocognitive outcome. CONCLUSION The available literature is so far in support of ETV as a valid and effective treatment modality in hydrocephalic patients. No sufficient evidence is available to justify resorting to shunting on the premise that it is associated with a better neurocognitive outcome.

Abstract
AbstractBackground: Cognitive dysfunction is a common complaint associated with obstructive hydrocephalus. The purpose of this study was to determine the effect of endoscopic third ventriculostomy (ETV) on the neuropsychological outcome in patients presenting with cognitive decline and obstructive hydrocephalus. Methods: A retrospective review of patients who underwent ETV at the University of Calgary and had both pre and post operative neuropsychological testing, was completed. Presenting clinical features, etiology of hydrocephalus and ventricle size utilizing frontal occipital horn ratio was obtained. Outcomes and complications of the ETV were recorded. Detailed measures of intelligence, attention and concentration, executive function, visual and verbal memory, language functions and fine motor skills were completed. Post treatment change was determined utilizing Reliable Change Index. Results: A total of 13 patients were identified. Etiology of the hydrocephalus was aqueductal stenosis in 8 and tectal glioma in 4. The majority of patients (11 of 13, 85%) demonstrated cognitive dysfunction at the borderline (≤1 SD) or impairment level (≤1.5 SDs) in at least one domain. Nine patients (69%) showed reliable improvement in at least one cognitive domain. The greatest improvement was seen with visual memory (42%). One quarter to one third of patients demonstrated improvement on tests of intelligence quotient, verbal memory, attention and concentration, and executive function. Two patients declined in executive functioning. Ventricle size improved in eight patients. Conclusions: ETV is a safe effective procedure, capable of producing reliable improvements in cognitive dysfunction with hydrocephalus. Patients with cognitive complaints alone may benefit from ETV.
