Abstract
BACKGROUND Neonatal intraventricular hemorrhage (IVH) may evolve into posthemorrhagic hydrocephalus and cause neurodevelopmental impairment, becoming a common complication of premature infants, occurring in up to 40% of preterm infants weighing less than 1,500 g at birth. Around 10 to 15% of preterm infants develop severe (grades III-IV) IVH. These infants are at high risk of developing posthemorrhagic hydrocephalus. Neuroendoscopic lavage (NEL) is a suitable alternative for the management of this pathology. In this study, an endoscopic surgical approach directed toward the removal of intraventricular hematoma was evaluated for its safety and efficacy. METHODS Between August 2016 and December 2019 (29 months), 14 neonates with posthemorrhagic hydrocephalus underwent NEL for removal of intraventricular blood by a single senior neurosurgeon. Complications such as reintervention and ventriculoperitoneal (VP) shunt placement were evaluated prospectively with an 18-month follow-up on average. RESULTS In total, 14 neonates with IVH grades III and IV were prospectively recruited. Of these, six neonates did not need a VP shunt in the follow-up after neuroendoscopy (group 1), whereas eight neonates underwent a VP shunt placement (group 2). Nonsignificant difference between the groups was found concerning days after neuroendoscopy, clot extraction, third ventriculostomy, lamina terminalis fenestration, and septum pellucidum fenestration. In group 2, there was shunt dysfunction in five cases with shunt replacement in four cases. CONCLUSION NEL is a feasible technique to remove intraventricular blood degradation products and residual hematoma in neonates suffering from posthemorrhagic hydrocephalus. In our series, endoscopic third ventriculostomy (ETV) + NEL could be effective in avoiding hydrocephalus after hemorrhage (no control group studied). Furthermore, patients without the necessity of VP-shunt had a better GMFCS in comparison with shunted patients.

Abstract
Background We present two pediatric cases, a neonate and an infant, who presented with treatment-refractory ventriculitis and multiloculated hydrocephalus treated with simultaneous intraventricular endoscopy and antibiotics. This is the first report of this combined therapy in children. Case Description Using intraventricular endoscopic surgery and antibiotics, hydrocephalus was treated with a minimum number of ventricular shunt systems. In addition, treatment-refractory ventriculitis was treated in both patients using intraventricular antibiotics. Conclusion Endoscopic surgery and intraventricular antibiotic administration are useful strategies for treating multiloculated hydrocephalus and ventriculitis in children.

Abstract
BACKGROUND Endoscopic third ventriculostomy (ETV) is usually performed under general anesthesia (GA) with proper head immobilization. However a few patients with hydrocephalus (HCP) may not be suitable for GA. Once the surgeon is familiar with endoscopic ventricular anatomy and gains adequate surgical experience with the procedure, ETV can be attempted under local anesthesia (LA) in selected patients. Here we discuss our experience of treating 32 patients of HCP with ETV under LA. METHODS 32 symptomatic HCP patients with in the age range of 13 and 65 years, conscious, alert, cooperative and at high risk for GA owing to deranged liver or renal function, associated co-morbidities, pregnancy were considered for ETV under scalp block. All patients were evaluated for any discomfort during the surgical intervention. RESULT All procedures were completed under LA. Four patients needed additional sedation prior to the scalp block to alleviate their apprehension. Four patients complained of bilateral orbital pain. In three it coincided with irrigation of fluid lower than body temperature. One patient had pain while touching the dorsum sella and needed analgesic supplement. All of them improved and none required additional CSF diversion within the average follow up of 9.5 months. CONCLUSION ETV can be performed under local anesthesia in conscious, alert and cooperative patients in experienced hands. Unnecessary stimulation of the painful structures should be avoided and fluid for irrigation should be at body temperature. This ensures patient comfort and safety of the procedure.

Abstract
Complex hydrocephalus or loculated hydrocephalus is a challenging problem in the field of pediatric neurosurgery. Early diagnosis and treatment are paramount in order to ensure success of treatment. Therefore, alertness is required among pediatricians who are dealing with premature children and children having meningitis and/or intraventricular hemorrhage. Disproportionate hydrocephalic changes in CT scan of the brain are suspicious, whereas gadolinium-enhanced multiplanar MR imaging (axial, sagittal, and coronal) is the best diagnostic modality. The definitive treatment is surgical, yet the approach remains a matter of debate. Cyst fenestration, communicating the isolated compartments together and with the ventricular system, is the main strategy of treatment. Cyst fenestration can be performed through either microsurgery or endoscopy, in order to improve the hydrocephalus, decrease number of shunts, and reduce shunt revision rates. However, the endoscopic procedure has an advantage over microsurgery of being simple and minimally invasive. It is evident that uniloculated hydrocephalus carries better prognosis than multiloculated hydrocephalus; this can be attributed to the initial pathological disease contributing to the ventricular compartmentalization. Because of the bad prognosis in multiloculated hydrocephalus, and because there are few numbers of patients available in any given center, a multicentric prospective study with long-term follow-up evaluating the results of outcome and quality of life is warranted.

Abstract
ObjectiveHydrocephalus is common after ventriculitis. This study explores hydrocephalus's clinical characteristics following pyogenic ventriculitis due to multidrug-resistant and extensively drug-resistant Acinetobacter baumannii and Klebsiella pneumoniae.Patients and MethodsWe retrospectively reviewed patients with post-neurosurgical pyogenic ventriculitis due to multidrug-resistant and extensively drug-resistant A. baumannii and K. pneumoniae in our department between January 2014 and June 2020. Once diagnosed, patients received intraventricular lavage followed by daily intraventricular administration of Colistin (polymyxin-E). The patient's clinical/radiographic findings were analyzed and evaluated 6 months after discharge.ResultsIn total, 48 cases were included in this study, and 25% were female. The median age was 45 (SD ± 15) years old. Median intraventricular Colistin administration to acquire sterile cerebrospinal fluid (CSF) was 20 days. Forty-one patients developed hydrocephalus; among them, 18 (43%) had multiloculated hydrocephalus (MLH), 23 (56%) had uni/non-loculated hydrocephalus (ULH/NLH), and 7 (17%) did not develop hydrocephalus. The patients with MLH had (15 days) delayed initiation of intraventricular irrigation (p < 0.022). They had (32 days) longer intraventricular Colistin (p < 0.003) and showed worse outcomes in terms of Glasgow outcome score (GOS) at 6 months follow-up than those without hydrocephalus. The mean score of the MLH group was 1.67 (SD1.23), and ULH/NLH was 2.61 (SD1.4) at p < 0.008.ConclusionMultiloculated hydrocephalus is common in patients receiving delayed intraventricular administration of Colistin and required a longer duration on intraventricular Colistin to treat the pyogenic ventriculitis caused by multidrug/extensive drug-resistant A. baumannii and K. pneumoniae. It is associated with worse clinical outcomes.

Abstract
Multiloculated hydrocephalus has an overall dismal functional outcome; imaging, early diagnosis, and technological advancements have made new roads in its management. Thirty infants with multiloculated hydrocephalus were studied. Progressive enlargement of the head was the most common presentation in 77%; of these, 47% were treated for neonatal meningitis and septicemia and 20% had suffered birth trauma. The majority required a single ventriculoperitoneal shunt; nine of them required multiple shunts; and six were managed with endoscopic fenestration and endoscopic third ventriculostomy. On follow-up, shunt malfunction was the most common complication. Only 26% of the survivors could achieve normal, neuropsychological developments. The mortality in this series is 6.7%.

Abstract
Background Management of complex/multiloculated/septated hydrocephalus is challenging. Neuroendoscopy has been well-established when compared to multiple shunt placements in management of multiloculated hydrocephalus (MH). The main aim of neuroendoscopy is to convert multiple locules into a single locule and drain it by either third ventriculostomy or ventriculoperitoneal shunt. Objective The objective is to reduce the number of surgical procedures and improve the quality of life. Neuroendoscopy avoids multiple shunt placement and need for revision of shunt. Methods Literature review regarding natural history, pathogenesis, classification and management of complex/uni/multiloculated hydrocephalus was extensively done and our minimal experience with these cases has been taken into consideration. Conclusion Neuroendoscopy when combined with frameless neuronavigation is reliable, accurate, and extremely useful in maintaining orientation and localizing the appropriate fenestration site in MH where anatomical landmarks are grossly distorted.

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
BACKGROUND A wide variety of intracranial cysts is known to occur in infants. If symptomatic, they require treatment; the ideal surgical treatment and indications of surgery are yet a matter of discussion. Traditional treatment is either by cystoperitoneal shunting, or microsurgical fenestration. Endoscopic treatment is an alternative procedure that avoids the invasiveness of open craniotomy and the complications caused by shunting. METHODS This article reviews the endoscopic treatment of intracranial cysts in infants. The author presents personal experience by reviewing the results of endoscopic treatment in different subgroups among his series of pediatric patients extending over 20 years. RESULTS Different types of intracranial cysts in infants were discussed and the role of endoscopy in the management of these patients was reviewed. The author also presented the results of endoscopic treatment of a personal series including 87 infants with intracranial cysts operated by the endoscopic procedure. CONCLUSIONS It has been recommended to use the endoscopic procedure in the treatment of intracranial cysts in infants, because it is effective, simple, minimally invasive, and associated with low morbidity and mortality rates. However, an important prerequisite is the presence of an area of contiguity with the subarachnoid cisterns and/or the ventricular system.

Abstract
Background Multiloculated hydrocephalus (MLH) is associated with increased intracranial pressure, with intraventricular septations, loculations, and isolation of parts of the ventricular system. Search continues for ideal surgical remedy capable of addressing the dimensions of the problem. We aimed to evaluate endoscopic septal fenestration and pellucidotomy combined with proximal shunt tube refashioning and further advancement into isolated loculations of the ventricular system containing choroid plexus. Methods This retrospective study was conducted on 55 patients with symptomatic complex MLH who underwent endoscopic surgery. The collected data included patients' age, gender, presenting manifestations, operative details, rate of remission of preoperative clinical and imaging signs, postoperative complications, redo surgery, or extra shunt hardware insertion. Patients were divided into Group A (underwent the standard technique of endoscopic multiseptal wide fenestration and final ventriculoperitoneal shunt insertion) and Group B (modified technique by adding extra side ports along the proximal shunt hardware). Results Groups A and B included 25 and 30 patients, respectively. The percentage of patients showing improvement of almost all manifestations was higher in Group B compared to Group A, with no significant difference (P > 0.05). Group B had lower rate of complications (20% vs. 36%, P = 0.231), insertion of two shunts (16.7% vs. 20%, P = 1.000), and redo surgery (20% vs. 44%, P = 0.097). Conclusion The modified technique was associated with better outcomes in terms of the use of single shunt and redo surgery. Launching randomized clinical trials to compare the two techniques are recommended to ascertain the efficacy of the modified technique.

Abstract
OBJECTIVE The authors performed a retrospective review of children diagnosed with multiloculated hydrocephalus (MLH) in our institute. The goal was to analyze the different diagnostic and therapeutic modalities used with special emphasis on CT ventriculography (CTV). METHODS Male and female patients below the age of 18 years diagnosed with MLH were included. Cases of uniloculated hydrocephalus like entrapped temporal horn or isolated fourth ventricle were excluded. We used iohexol for CTV and gadodiamide for MR ventriculography. Neuroendoscopic procedures performed were endoscopic fenestration, endoscopic third ventriculostomy (ETV), endoscopic septostomy, endoscopic aqueductoplasty, or a combination of the above. The cohort was divided into two groups (endoscopic or shunt) based on initial surgical intervention. RESULTS A total of 52 patients were included, with 43 boys and 9 girls. The average age of presentation was 7.7 months. The most common predisposing factor for MLH was neonatal meningitis seen in 30 patients. Mean duration of follow-up was 39 months. CTV was used in 26 patients and MR ventriculography in three patients. In one patient, the diagnosis of MLH was ruled out after ventriculography. Patients who underwent ETV only had the best outcome with 71.4% success rate. At the end of follow-up, 14 patients (27%) were shunt independent. CONCLUSIONS The present study indicates that CTV helps to accurately define the anatomy of the ventricles and determine the site of physiological CSF obstruction. This helps in therapeutic planning and in avoiding misdiagnoses. Further, neuroendoscopy has the potential to lead to shunt independence in some patients.

Abstract
INTRODUCTION Treatment or multilevel hydrocephalus is a complex problem. Neuroendoscopic interventions, make it possible to combine minimal invasiveness with the possibility of fenestration of several cysts during one procedure and thereby eliminate multi-level occlusion. We present our the experience of using a neodymium YAG laser (Nd-YAG laser) as an additional tool to improve the treatment results of patients with non-communicating hydrocephalus. MATERIAL AND METHODS This study included 10 patients aged from 5 months to 8 years who underwent endoscopic interventions with the use of rigid endoscope with frameless navigation. A surgical laser with a radiation wavelength of 1.064 μm was used as the main tool for fenestrating the walls of the cysts. RESULTS 13 endoscopic laser interventions were performed in 10 patients with multilevel hydrocephalus. In 3 children, the two-stage treatment was chosen in due to the impossibility of simultaneous fenestration of all cysts. The interval between procedures was 1 month in two cases and 11 months in one case. We managed to compensate for cerebrospinal fluid disturbances in each patient, positive dynamics in the condition was noted. The duration of postoperative stay averaged 8 days (from 4 to 13 days). There were no deaths in the study group. All patients were discharged in good condition. Average follow-up duration was 14 months (from 8 to 25 months). During the observation, the condition of the patients remained stable; there was no need for repeated operations. CONCLUSION Combined use of bypass operations, endoscopic techniques and neural navigation may improve the results of treatment of patients with multilevel hydrocephalus. Data presented in this article demonstrates the safety and effectiveness of the clinical use of laser radiation as an additional tool for interventions in patients with this condition.

Abstract
OBJECTIVE To evaluate the role of endoscopic cyst fenestration and endoscopic guided VP shunt insertion in multi-loculated hydrocephalus in children. METHOD A retrospective analysis was performed on 20 patients with multi-loculated hydrocephalus who underwent endoscopic cyst fenestration (ECF) alone or in combination with VP shunt revision or insertion between August 2014 and December 2016 with the extended follow-up period to December 2017. RESULTS Thirty-one ECFs were performed: ECF alone, 10 operations in 8 cases, and 21 ECFs with shunt insertion in 12 cases. Eighteen of 20 patients required a VP shunt, 7 cases required multiple shunts. All patients with a previous shunt remained shunt dependent; and 6 cases with no prior shunt underwent endoscopic guided ventricular catheter insertion after ECF; only 2 cases did not require a shunt after ECF. The rate of repeated ECFs was 0.25 operations/year and the shunt revision rate was 0.11 operations/year. VP shunt or cystoperitoneal shunt without repeat ECF was used in 7 cases (35%). Mean duration between operations was 71 days in repeated ECF and 16 days in added-on shunt. The most common cause of re-operations was new formation of intraventricular fibrosis or compartmentalization causing ventricular catheter blockage. CONCLUSION Endoscopic cyst fenestration and endoscopic assisted VP shunt insertion minimize shunt complications in multi-loculated hydrocephalus. Shunt independence is unusual.

Multiloculated hydrocephalus (MLH) is a condition in which patients have multiple, separate abnormal cerebrospinal fluid collections with no communication between them. Despite technical advancements in pediatric neurosurgery, neurological outcomes are poor in these patients and the approach to this pathology remains problematic especially given individual anatomic complexity and cerebrospinal fluid (CSF) hydrodynamics. A uniform surgical strategy has not yet been developed. Current treatment options for MLH are microsurgical fenestration of separate compartments by open craniotomy or endoscopy, shunt surgery in which multiple catheters are placed in the compartments, and combinations of these modalities. Craniotomy for fenestration allows better visualization of the compartments and membranes, and it can offer easy fenestration or excision of membranes and wide communication of cystic compartments. Hemostasis is more easily achieved. However, because of profound loss of CSF during surgery, open craniotomy is associated with an increased chance of subdural hygroma and/or hematoma collection and shunt malfunction. Endoscopy has advantages such as minimal invasiveness, avoidance of brain retraction, less blood loss, faster operation time, and shorter hospital stay. Disadvantages are also similar to those of open craniotomy. Intraoperative bleeding can usually be easily managed by irrigation or coagulation. However, handling of significant intraoperative bleeding is not as easy. Currently, endoscopic fenestration tends to be performed more often as initial treatment and open craniotomy may be useful in patients requiring repeated endoscopic procedures.

Abstract
Context: Multiloculated hydrocephalus remains one of the most challenging neurosurgical problems. In this study, we use frameless navigation during endoscopic interventions to improve the efficiency of operations. Subjects and Methods: Nine navigated endoscopic procedures were performed in 8 children with various forms of multiloculated hydrocephalus from March 2013 to June 2014. Preoperatively, the optimal entry point for fenestration of several cysts was determined on the basis of magnetic resonance data. During surgery, rigid endoscope was registered in neuronavigation system for making the connection between separated ventricles and cysts. The final stage of the operation was to conduct a stent through the working channel of the endoscope for implantation of a shunt. Results: Number of compartments interconnected by an operation ranged from 3 to 5. Seven interventions were performed simultaneously with the shunt implantation. The follow-up period ranged from 9 to 15 months. The clinical improvement as a result of the operation was achieved in all children. The follow-up included clinical examination and evaluation of magnetic resonance imaging. Additional surgery was necessary in two patients: The first 5 months later, the second 1-year after endoscopic intervention. Conclusion: Application of frameless navigated neuroendoscopy makes this kind of operations the most efficient and safe for the patient.

Abstract
INTRODUCTION The use of the endoscopic technique largely improves treatment outcomes in patients with multilocular hydrocephalus. However, impaired anatomy and the lack of usual landmarks often cause problems in planning and intraoperative identification of changed structures. The use of frameless navigation during endoscopic interventions can significantly facilitate surgeon tasks and increases the efficacy of surgery. During surgery, the neuronavigation system visualizes a rigid endoscope that interconnects separated ventricles and cysts. Surgery can be completed with guiding a stent through an operating channel of the endoscope and implanting a shunt system. MATERIAL AND METHODS Ten children underwent 11 endoscopic interventions using frameless intraoperative navigation at our clinic in 2013-2014. The number of surgically interconnected compartments ranged from 3 to 5. Simultaneous placement of a shunt system was performed in 8 of 11 interventions. RESULTS Clinical improvement as a result of the operation was achieved in all children. 2 patients underwent re-operations 5 months and 1 year after endoscopic intervention. CONCLUSION Thus, the use of frameless navigation during endoscopic interventions makes their implementation most efficient and safe for the patient.

Abstract
Objectives: We present a case of a multiloculated third ventricular arachnoid cyst to describe a novel technique for definitive management of these lesions via direct endoscopic fenestration and CSF diversion utilizing separate trajectories that offers superior visualization and avoids forniceal injury. Methods and Results: We present a case of a 33-year-old woman with progressive headache and worsened vision, a known history of a multiloculated third-ventricular arachnoid cyst, and imaging findings consistent with cyst expansion and worsened obstructive hydrocephalus. We then describe the dual-trajectory approach for simultaneous cyst fenestration and endoscopic third ventriculostomy that ultimately resulted in successful treatment of her cyst and hydrocephalus. Conclusions: Dual-trajectory endoscopic approach utilizing double burr holes should be considered when addressing lesions of the third ventricle causing obstructive hydrocephalus.

Abstract
OBJECT Cystic lesions in the atrium (trigone) of the lateral ventricle may become symptomatic due to obstruction of physiological CSF circulation and/or from mass effect on adjacent structures. A minimally invasive approach that not only allows for straightforward access to multiple regions of the atrial cyst wall, but also enables direct inspection of the entire lateral ventricular system, has not been elaborated. In this paper the authors describe their experience with the endoscopic transoccipital horn approach for treating cystic lesions in the atrium of the lateral ventricle. METHODS A retrospective review was performed of all patients who underwent endoscopic surgical treatment for cysts in the atrium of the lateral ventricle between 1999 and 2014. RESULTS The cohort consisted of 13 consecutive patients who presented with symptomatic lateral ventricular entrapment due to the presence of an atrial cyst. There were 9 male and 4 female patients, with a median age of 5 years. Headache was the most common complaint at presentation. The transoccipital horn approach facilitated successful cyst reduction and fenestration in all cases. Temporal and occipital horn entrapment was reversed in all cases, with reestablishment of a physiological CSF flow pattern throughout the ventricles. Hydrocephalus was also reversed in all patients presenting with this neuroimaging finding at presentation. No cyst or ventricular entrapment was noted to recur during a mean follow-up period of 36 months. No patient in the study cohort required repeat surgery or permanent CSF diversion postoperatively. CONCLUSIONS The endoscopic transoccipital horn approach represents a safe and effective treatment strategy for patients with symptomatic atrial cysts of the lateral ventricle. Using this minimally invasive technique, all poles of the lateral ventricular system can be visualized and the unobstructed flow of CSF can be confirmed after cyst resection obviating the need for additional diversion.

Abstract
OBJECT Arachnoid cysts account for 1% of all intracranial lesions. They usually occur in the subarachnoid space of the major cerebral fissures and arachnoid cisterns. They are very rarely located within the brain parenchyma devoid of communication with the subarachnoid space. The author of this study evaluated the role of endoscopy in the treatment of intraparenchymal arachnoid cysts (IPACs), which have a paraventricular location noncontiguous with the basal cisterns. METHODS The records of all patients who had undergone surgery performed by one neurosurgeon between March 2004 and October 2011 were retrospectively reviewed to find cases of arachnoid cysts with a paraventricular location noncontiguous with the basal cisterns that were treated with a purely endoscopic cystoventriculostomy. Data were collected, summarized, and analyzed as regards improvement in symptomatology, decrease in cyst size, improvement in hydrocephalus, incidence of complications, surgical failure, and incidence of recurrence. RESULTS Twelve pediatric patients with symptomatic IPACs were included in this study. The group included 7 boys and 5 girls with a mean age of 5.2 years. All of the patients had undergone endoscopic cystoventriculostomy. In addition, endoscopic third ventriculostomy had been performed during the same operative session in 3 patients who had associated hydrocephalus. Significant clinical improvement occurred in 10 patients (83.3%). Postoperative imaging showed a reduction in the cyst size in 9 patients (75%), whereas the cyst size was unchanged in the remaining 3 patients (25%). A reduction in ventricle size occurred in 2 (66.7%) of the 3 patients who had hydrocephalus. A postoperative subdural hygroma occurred in 2 patients (16.7%) and required the insertion of a subduroperitoneal shunt in 1 patient. During the follow-up period (mean 42.5 months), 1 patient had a recurrence and required a repeat endoscopic procedure. CONCLUSIONS Endoscopic cystoventriculostomy is recommended in the treatment of symptomatic IPACs. It maintains the basic strategy of cyst fenestration into the lateral ventricle without either the invasiveness of open craniotomy or the implantation of shunt systems. The procedure is simple, effective, and minimally invasive. It saves operative and recovery times and is associated with low morbidity and mortality rates.

Abstract
Object Neonatal intraventricular hemorrhage (IVH) may evolve into posthemorrhagic hydrocephalus and cause neurodevelopmental impairment. In this study, an endoscopic surgical approach directed toward the removal of intraventricular hematoma was evaluated for its safety and efficacy. Methods Between August 2010 and December 2012 (29 months), 19 neonates with posthemorrhagic hydrocephalus underwent neuro endoscopic lavage for removal of intraventricular blood remnants. During a similar length of time (29 months) from March 2008 to July 2010, 10 neonates were treated conventionally, initially using temporary CSF diversion via lumbar punctures, a ventricular access device, or an external ventricular drain. Complications and shunt dependency rates were evaluated retrospectively. Results The patient groups did not differ regarding gestational age and birth weight. In the endoscopy group, no relevant procedure-related complications were observed. After the endoscopic lavage, 11 (58%) of 19 patients required a later shunt insertion, as compared with 100% of infants treated conventionally (p < 0.05). Endoscopic lavage was associated with fewer numbers of overall necessary procedures (median 2 vs 3.5 per patient, respectively; p = 0.08), significantly fewer infections (2 vs 5 patients, respectively; p < 0.05), and supratentorial multiloculated hydrocephalus (0 vs 4 patients, respectively; p < 0.01) [corrected].Conclusions Within the presented setup the authors could demonstrate the feasibility and safety of neuro endoscopic lavage for the treatment of posthemorrhagic hydrocephalus in neonates with IVH. The nominally improved results warrant further verification in a multicenter, prospective study.

Abstract
OBJECT The treatment of uniloculated hydrocephalus is a difficult problem in pediatric neurosurgery. Definitive treatment is surgical, yet the approach remains controversial. This study evaluates the role of endoscopic cyst fenestration (ECF) in the management of this disease. METHODS Thirty-one pediatric patients with uniloculated hydrocephalus who underwent endoscopic surgery, performed by the author, between May 1999 and December 2010 constitute the patient group for this study. The patients included 17 boys and 14 girls, with ages ranging from 5 months to 5 years (mean 22.9 months). Patients with multiloculated hydrocephalus were not included. The patients' charts were reviewed for demographic data, radiological findings, information regarding morbidity, improvement of hydrocephalus, incidence of recurrence, shunt dependency, and the need for shunt revision. RESULTS Neuroepithelial cysts were the most common cause (17 cases), followed by postoperative gliosis due to previous shunt infection (9 cases), intraventricular hemorrhage (3 cases), and meningitis (2 cases). Multiplanar MRI was reliable in making the diagnosis and is indicated if CT shows disproportionate hydrocephalus. Surgical treatment included ECF (31 cases), endoscopic revision of malfunctioning preexisting shunts (9 cases), endoscopic third ventriculostomy (4 cases), and placement of a new shunt (3 cases). Endoscopic cyst fenestration was easily performed in all the cases, with devascularization of the cyst wall by coagulation to prevent recurrence. Improvement of hydrocephalus was observed in 26 cases (83.9%). Among the group of patients without prior shunts (22 cases), 3 patients (13.6%) required repeat ECF and 3 patients (13.6%) required placement of a shunt (new shunt placement). In the 9 patients with preexisting shunts, endoscopy reduced the mean rate of shunt revision from 2.7 revisions per year before fenestration to 0.25 per year after fenestration. Four of these 9 patients had multiple shunts, which could be converted to a single shunt; however, repeat ECF was necessary in all 9 patients. With a mean follow-up duration of 4.3 years, none of the patients with a prior shunt was able to become shunt-independent, whereas 86.4% of patients without a prior shunt were able to avoid shunt placement. Endoscopic complications were reversible (unilateral subdural effusion in 5 cases, minor arterial bleeding in 2 cases, CSF leakage in 1 case), and there was no death (0%). CONCLUSIONS Endoscopic cyst fenestration is recommended in the treatment of uniloculated hydrocephalus because it is effective, simple, minimally invasive, and associated with low morbidity and mortality rates. The fact that all previously shunt-treated patients needed repeat ECF and that none of these patients was able to become shunt-independent makes it clear that uniloculated hydrocephalus due to postoperative gliosis induced by previous shunt infection carries the worst prognosis.

Abstract
Endoscopic third ventriculostomy (ETV) is considered as a treatment of choice for obstructive hydrocephalus. It is indicated in hydrocephalus secondary to congenital aqueductal stenosis, posterior third ventricle tumor, cerebellar infarct, Dandy-Walker malformation, vein of Galen aneurism, syringomyelia with or without Chiari malformation type I, intraventricular hematoma, post infective, normal pressure hydrocephalus, myelomeningocele, multiloculated hydrocephalus, encephalocele, posterior fossa tumor and craniosynostosis. It is also indicated in block shunt or slit ventricle syndrome. Proper Pre-operative imaging for detailed assessment of the posterior communicating arteries distance from mid line, presence or absence of Liliequist membrane or other membranes, located in the prepontine cistern is useful. Measurement of lumbar elastance and resistance can predict patency of cranial subarachnoid space and complex hydrocephalus, which decides an ultimate outcome. Water jet dissection is an effective technique of ETV in thick floor. Ultrasonic contact probe can be useful in selected patients. Intra-operative ventriculo-stomography could help in confirming the adequacy of endoscopic procedure, thereby facilitating the need for shunt. Intraoperative observations of the patent aqueduct and prepontine cistern scarring are predictors of the risk of ETV failure. Such patients may be considered for shunt surgery. Magnetic resonance ventriculography and cine phase contrast magnetic resonance imaging are effective in assessing subarachnoid space and stoma patency after ETV. Proper case selection, post-operative care including monitoring of ICP and need for external ventricular drain, repeated lumbar puncture and CSF drainage, Ommaya reservoir in selected patients could help to increase success rate and reduce complications. Most of the complications develop in an early post-operative, but fatal complications can develop late which indicate an importance of long term follow up.

Abstract
PURPOSE Loculated hydrocephalus is a condition in which discrete fluid-filled compartments form in or in relation to the ventricular system of the brain. Both uni- and multiloculated variants exist, with marked differences in outcome. However, several competing and seemingly interchangeable nomenclatures exist, and none address the pathophysiological basis of the condition. To clarify current treatment options, we carried out a review of the literature. METHODS A protocol describing search strategy and inclusion criteria was prepared in advance, and a search of MEDLINE, the Cochrane Database of Systematic Reviews, and the U.S. NIH ClinicalTrials.gov database was carried out with the search terms: "multicystic," "multiloculated," "multicompartment," "uniloculated," and "loculated." All were used in conjunction with the search term "hydrocephalus." RESULTS A single study with a control group was found. Remaining reports are purely case series. Research efforts are hampered by unclear and seemingly interchangeable nomenclatures, which makes comparison between studies difficult. There is a paucity of studies of high methodological quality concerning choice of treatment. At the case series level, evidence is in favor of the neuroendoscopic approach. CONCLUSIONS In order to ensure a consistent nomenclature as well as to guide future research, we propose a new system of classification for loculated hydrocephalus. It acknowledges the differences between uniloculated and multiloculated hydrocephalus, and goes beyond a pure anatomical model. For future research, it enables us to clearly characterize subgroups, which is essential if we are to advance our understanding and level of care for this challenging group of patients.

Abstract
BACKGROUND The management of complex hydrocephalus is challenging. There is no consensus of the best treatment for isolated fourth ventricles, arachnoid cysts, and multiloculated hydrocephalus, although the avoidance of multiple shunts is desirable. We reviewed our experience with the use of endoscopic techniques to simplify complex multicompartmental hydrocephalus to determine its efficacy and safety. METHODS We performed a retrospective study of 114 consecutive adults and children undergoing endoscopic management of hydrocephalus by a single surgeon. The type of hydrocephalus and endoscopic procedure performed were recorded. The management algorithm for simplification of complex hydrocephalus is reviewed. All patients were followed up in the office or by telephone. RESULTS A total of 143 endoscopic procedures were performed on 114 patients with a mean age of 4.4 years (4 weeks to 32 years). The endoscopic procedures performed included cyst fenestration, septum pellucidotomy, endoscopic third ventriculostomy, aqueductal plasty with and without stent, and removal of cystercicotic cysts. Twenty-two (19.3%) patients had planned staged endoscopic procedures. Mean follow up was 65 months (range 33-122 months). Eighty-two (72%) patients were reduced to 1 shunt, shunt independence was achieved in 32 (28%) patients, and only 8 (11%) patients required shunt revision in the follow-up period. CONCLUSIONS Endoscopic simplification of complex hydrocephalus enables dependence on only a single shunt in the majority of patients, and a significant proportion achieve shunt independence. Endoscopic management should be considered before the placement of a second shunt, and some cases require staged endoscopic procedures to adequately communicate multicompartmental hydrocephalus.

Abstract
OBJECTIVE The study aims to assess the treatment of progressive multiloculated hydrocephalus. In a retrospective study, the authors reviewed their experience with different treatment modalities. METHODS We have retrospectively evaluated 93 patients with progressive multiloculated hydrocephalus operated between 1988 and 2010. They represented around 2% (93/4,565) of all patients surgically treated for nontumoral hydrocephalus during this period of time at our institution. RESULTS Ventricular septal fenestration was carried out by craniotomy in 27 patients, endoscopic septum pellucidum fenestration in 19, endoscopic ventricular septal fenestration in 18, choroid plexectomy-fulguration in 14 (8 endoscopically and 6 by craniotomy), and third ventriculostomy in 2. Hydrocephalus was resolved in 21 patients with shunting, placing two ventricular catheters as the only procedure. Out of the 72 remaining patients, 34 underwent only one treatment, 30 two treatments, and 8 three or more procedures. The majority of patients ultimately required CSF shunt placement with only one ventricular catheter. CONCLUSIONS (1) Multiloculated hydrocephalus is a severe disease in which no single treatment has clearly been shown to be superior. (2) The goal of treatment is to restore communication between isolated intraventricular compartments in order to create the possibility of the implantation of a simple shunt with only one intraventricular catheter. More than improving the quality of life the patient, the objective is to reduce the number of surgical procedures. (3) Given the complexity of multiloculated hydrocephalus, each patient must be studied individually, and no procedure proposed by the literature should be ruled out, no matter how old fashioned may appear.

Abstract
Improvement in fiber optics and imaging paved the way for tremendous advancements in neuroendoscopy. These advancements have led to increasingly widespread use of the endoscope in neurosurgical procedures, which in turn incited a technological revolution leading to new approaches, instruments, techniques, and a diverse armamentarium for the treatment of a variety of neurosurgical disorders. Soft-tissue removal is often a rate-limiting aspect to endoscopic procedures, especially when the soft tissue is dense or fibrous. The authors review a series of cases involving patients treated between August 2009 and October 2010 with a new device (the NICO Myriad), a non-heat-generating, oscillating, cutting, and tissue removal instrument that can be used through the working channel of the endoscope as well as in open neurosurgical procedures. They used this device in 14 purely endoscopic intracranial procedures and 1 endoscope-assisted keyhole craniotomy. They report that the device was easy to use and found that tissue resection was more efficient than with other available endoscopic instruments, especially in the resection of fibrotic tissue. There were no observed device-related complications. The authors discuss the technical aspects of using this device in endoscopic resection of pituitary tumors, craniopharyngiomas, and colloid cysts. They also demonstrate its use in hydrocephalus and intraventricular clot removal and discuss its potential use in other neurosurgical disorders.

Abstract
OBJECT Multiloculated hydrocephalus remains a challenging condition to treat in the pediatric hydrocephalic population. In a retrospective study, the authors reviewed their experience with navigated endoscopy to treat multiloculated hydrocephalus in children. METHODS Between April 2004 and September 2008, navigated endoscopic procedures were performed in 16 children with multiloculated hydrocephalus (median age 8 months, mean age 16.1 +/- 23.3 months). In all patients preoperative MR imaging was used for planning entry sites and trajectories of the endoscopic approach for cyst perforation and catheter positioning. Intraoperatively, a rigid endoscope was tracked by the navigation system. For all children the total number of operative procedures, navigated endoscopic procedures, implanted ventricular catheters, and drained compartments were recorded. In addition, postoperative complications and radiological follow-up data were analyzed. RESULTS In 16 children, a total of 91 procedures were performed to treat multiloculated hydrocephalus, including 29 navigated endoscopic surgeries. Finally, 21 navigated procedures involved 1 ventricular catheter and 8 involved 2 catheters for CSF diversion via the shunt. The average number of drained compartments in a shunt was 3.6 +/- 1.7 (range 2-9 compartments). In 9 patients (56%) a navigated endoscopic procedure constituted the last procedure within the follow-up period. One additional surgery was necessary in 3 patients (19%) after navigated endoscopy, and in 4 patients (25%) 2 further procedures were necessary after navigated endoscopy. Serial follow-up MR imaging demonstrated evidence of sufficient CSF diversion in all patients. CONCLUSIONS Navigated endoscopic surgery is a safe and effective treatment option for multiloculated hydrocephalus. The combination of the endoscopic approach and neuronavigation further refines preoperative planning and intraoperative orientation. The aim of treatment is to drain as many compartments as possible and as soon as possible, thereby establishing sufficient CSF drainage with few ventricular catheters in single shunt systems. Close clinical and radiological follow-up is mandatory because multiple revisions are likely.

Abstract
We describe an 8-year-old girl who presented with cranial nerve compression due to a brainstem cyst adjacent to the fourth ventricle and describe the first documented insertion of a grommet to form a conduit between a neuroepithelial cyst and ventricle. The patient presented with diplopia and headaches and was found to have the cystic lesion in the right pons. The patient underwent craniotomy, aspiration and fenestration with subsequent recurrence 8 months later. Definitive treatment involved insertion of a grommet. Surgical treatment of symptomatic neuroepithelial cysts can achieve full resolution of neurological deficits. Insertion of a grommet, as distinct from a shunt or fenestration procedure, has the potential to provide long-term resolution of these symptoms without recurrence.
