Shunt, endoscopic, and microsurgical management of trapped temporal horn following resection of lateral ventricle trigonal or peritrigonal tumors: A retrospective multicenter study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108643. [PMID: 39241539 DOI: 10.1016/j.ejso.2024.108643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 08/16/2024] [Accepted: 08/24/2024] [Indexed: 09/09/2024]
Abstract
OBJECTIVE To investigate the surgical management and outcomes of trapped temporal horn (TTH) following resection of lateral ventricle trigonal or peritrigonal tumors. METHODS Patients who underwent surgical treatment for TTH in three different tertiary centers between 2012 and 2022 were retrospectively studied. The primary outcome was reoperation rate. RESULTS Thirty-one patients were included for analysis. The underlying pathology was meningioma in 17 patients, central neurocytoma in 7, glioma in 4, ependymoma in 2, and cavernous malformation in 1. The median KPS score was 50 (range 10-90) and the mean volume of TTH was 53.1 ± 29.9 cm³ (range 14.8-118.6). Six patients (19.3 %) required multiple operations. A total of 39 procedures were performed, including 28 CSF shunting, 2 endoscopic septostomy, 3 microsurgical fenestration or temporal tip lobectomy via craniotomy, 2 decompressive craniectomy (DC), and 4 shunt revisions. Reoperation rates according to procedure were as follows: 10.7 % (3/28) for CSF shunting, 50 % (1/2) for endoscopic septostomy, 100 % (2/2) for DC, and 0 (0/3) for microsurgical fenestration or temporal tip lobectomy. CSF shunting tended to have a lower reoperation rate compared to other surgical approaches (p = 0.079). The reoperation rate was significantly higher for DC than for other surgical techniques (p = 0.025). CONCLUSION CSF shunting was the most frequently used technique with a relatively low revision rate. Long-term patency can be achieved through endoscopic septostomy in selected patients. Microsurgical fenestration or temporal tip lobectomy should be reserved for refractory cases. DC has limited effectiveness and should not be recommended.

Abstract
OBJECTIVE The goal of this study was to analyze the clinical outcomes of endoscopic third ventriculostomy (ETV) and endoscopic septostomy when shunt malfunction occurs in a patient who has previously undergone placement of a ventriculoperitoneal shunt. METHODS From 2001 to 2020 at Seoul National University Children's Hospital, patients who underwent ETV or endoscopic septostomy for shunt malfunction were retrospectively analyzed. Initial diagnosis (etiology of hydrocephalus), age at first shunt insertion, age at endoscopic procedure, magnetic resonance or computed tomography image, subsequent shunting data, and follow-up period were included. RESULTS Thirty-six patients were included in this retrospective study. Twenty-nine patients, 18 males and 11 females, with shunt malfunction underwent ETV. At the time of shunting, the age ranged from 1 day to 15.4 years (mean, 2.4 years). The mean age at the time of ETV was 13.1 years (range, 0.7 to 29.6 years). Nineteen patients remained shunt revision free. The 5-year shunt revisionfree survival rate was 69% (95% confidence interval [CI], 0.54-0.88). Seven patients, three males and four females, with shunt malfunction underwent endoscopic septostomy. At the time of shunting, the age ranged from 0.2 to 12 years (mean, 3.9 years). The mean age at the time of endoscopic septostomy was 11.9 years (range, 0.5 to 29.5 years). Four patients remained free of shunt revision or addition. The 5-year shunt revision-free survival rate was 57% (95% CI, 0.3-1.0). There were no complications associated with the endoscopic procedures. CONCLUSION The results of our study demonstrate that ETV or endoscopic septostomy can be effective and safe in patients with shunt malfunction.

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
OBJECTIVE The advent of neuroendoscopy revolutionized the management of complex hydrocephalus. Fenestration of the septum pellucidum (septostomy) is often a therapeutic and/or necessary intervention in neuroendoscopy. However, these procedures are not without risk. The authors sought to record the incidence and types of complications. They attempted to discern if there was decreased likelihood of septostomy complications in patients who underwent endoscopic third ventriculostomy (ETV)/choroid plexus cauterization (CPC) as compared with those who underwent other procedures and those with larger ventricles preoperatively. The authors investigated different operative techniques and their possible relationships to septostomy complications. METHODS The authors retrospectively reviewed all neuroendoscopic procedures with Current Procedural Terminology code 62161 performed from January 2003 until June 2019 at their institution. Septostomy, either alone or in conjunction with other procedures, was performed in 118 cases. Basic demographic characteristics, clinical histories, operative details/findings, and adverse events (intraoperative and postoperative) were collected. Pearson chi-square and univariate logistic regression analyses were performed. Patients with incomplete records were excluded. RESULTS Of 118 procedures, 29 (24.5%) septostomies had either intraoperative or postoperative complications. The most common intraoperative complication was bleeding, as noted in 12 (10.2%) septostomies. Neuroendocrine dysfunction, including apnea, bradycardia, neurological deficit, seizure, etc., was the most common postoperative complication and seen after 15 (12.7%) procedures. No significant differences in complications were noted between ventricular size or morphology or between different operative techniques or ventricular approaches. There was no significant difference between the complication rate of patients who underwent ETV/CPC and that of patients who underwent septostomy as a part of other procedures. Greater length of surgery (OR 1.013) was associated with septostomy complications. CONCLUSIONS Neuroendoscopy for hydrocephalus due to varying etiologies provides significant utility but is not without risk. The authors did not find associations between larger ventricular size or posterior endoscope approach and lower complication rates, as hypothesized. No significant difference in complication rates was noted between septostomy performed during ETV/CPC and other endoscopic procedures requiring septostomy.

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 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
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.

Abstract
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
Abstract
Intraventricular septations can lead to compartmentalization of the ventricles that can result in “complex or loculated hydrocephalus”. We report a case of 7 year old female child who underwent multiple shunt revisions where there was intraventricular entrapment of shunt catheter leading to obstruction of the shunt and malfunction. In present case we placed the ventricular catheter in contra-lateral ventricle with good clinical outcome. With the recent advancements endoscopic guided removal of the old malfunctioning ventricular catheters is considered the safest option.

Abstract
OBJECTIVE Multiloculated hydrocephalus may occur as a consequence of intraventricular hemorrhage or infection and is characterized by enlargement of multiple noncommunicating intraventricular and/or periventricular cysts. In this study, we report the outcomes of open and endoscopic fenestration for multiloculated hydrocephalus at our institution. METHODS Records of children who underwent endoscopic or open fenestration at St. Louis Children's Hospital from 1999 to 2011 were analyzed. The cause of MLH, operative parameters, length of hospital stay, and subsequent shunt intervention rate were recorded. RESULTS Twenty-five subjects were identified for study. Twelve subjects underwent open craniotomy and 13 underwent endoscopic fenestration. Endoscopic fenestration was associated with decreased blood loss, operative time, and length of stay (p = 0.003, 0.002, 0.02, respectively). Subjects undergoing craniotomy had an average of 5.1 ± 4.5 subsequent shunt-related interventions versus 3.1 ± 4.0 in the endoscopy group (p = 0.25). The craniotomy group's median subsequent shunt revision rate was 0.74 interventions per year versus 0.50 interventions per year in the endoscopy group (p = 0.51). Fifty percent of subjects in the open fenestration group required additional fenestration surgery compared to 38.5% in the endoscopic group (p = 0.70). CONCLUSION Both open and endoscopic fenestration appeared effective at improving shunt management. The endoscopic technique may offer advantages in operative time, blood loss, and length of hospital stay. These data suggest that endoscopic fenestration may be used as the initial approach for treatment of multiloculated hydrocephalus, with craniotomy and open fenestration used for more severe or refractory cases.

Abstract
Endoscopic treatment for hydrocephalus started in the early 20th century, but could not thrive due to poor illumination and magnification of the scope. In the 1950s, ventriculoperitoneal (VP) shunt became widely acceptable as standard treatment for hydrocephalus owing to the invention of well-designed valves and discovery of silicone, a biocompatible material for manufacturing shunt catheters. However, shunting is still far from being an ideal treatment because of its associated complications such as catheter malposition, blockage, and over- or under-drainage of cerebrospinal fluid. The shunt revision rates remained high in recent series. At the same time, endoscopy has undergone tremendous improvement in the latter half of the century and has emerged as an attractive alternative since the early 1990s. The article described the usage of endoscopy in the treatment of hydrocephalus, such as endoscopic third ventriculostomy, fenestration of multi-loculated hydrocephalus, and fenestration of septum pellucidum prior to VP shunting.

Abstract
OBJECT In this paper the authors' goal was to investigate the clinical usefulness of Gd-enhanced MR ventriculography (MRV) in pediatric patients affected by multiloculated hydrocephalus. METHODS Eighteen patients (11 boys and 7 girls, age range 2-14 months) with a diagnosis of multiloculated hydrocephalus were included in the study. After injection of gadodiamide (0.02-0.04 mmol) into the lateral ventricle by tapping the anterior fontanel, sagittal, coronal, and axial T1-weighted MR images were acquired. The location of the septations and the sites of obstruction of CSF flow were assessed. Postoperative MRV was obtained to confirm the results of endoscopic treatment in most complex cases. RESULTS No adverse events were observed after injection of contrast medium into the ventricular system. Preoperative MRV accurately defined the exact morphology of septae and ventricular walls in all cases. In 1 case the diagnosis of multiloculated hydrocephalus was ruled out. Sites of obstruction of CSF flow within the ventricular system were also well established. In 4 cases the multiple compartments were proven to intercommunicate. Postoperative MRV was useful in assessing the functional status of third ventriculostomy, aqueductoplasty, and other endoscopic fenestrations. CONCLUSIONS Magnetic resonance ventriculography is a safe, effective, and reliable technique. The accurate definition of the anatomy of the ventricles and the site of obstruction in multiloculated hydrocephalus can help to plan the most appropriate treatment and minimize the number of procedures. Although MRV is also useful during postoperative follow-up to determine the results of endoscopic treatment, it should be limited to particularly complex cases, due to its invasiveness.

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
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
INTRODUCTION Post-infective hydrocephalus refers to accumulation of fluid within the cranial cavity (hydrocephalus) secondary to either pyogenic or tuberculous meningitis. Whereas in the former condition, fibrous adhesions develop in the ventricles and arachnoid villi, in the latter, the fibrosis is mainly basal. METHODS This is a review of the author's personal series as well as published literature on post-infective hydrocephalus. CONCLUSION The aim of treatment in hydrocephalus following pyogenic meningitis is to sterilize the cerebrospinal fluid (CSF) and then to drain the ventricles after conversion of a multiloculated cavity into a single cavity. In hydrocephalus associated with tuberculous meningitis, CSF diversion is not always necessary and should be reserved for cases where clinical deterioration occurs pari passu with increase in ventricular size and intraventricular pressure.

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
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
OBJECTIVES The treatment of multiloculated hydrocephalus is a difficult problem in pediatric neurosurgery. Definitive treatment is surgical, yet the approach remains controversial. The author has therefore reviewed his results with endoscopic cyst fenestration (ECF) in the management of this disease. METHODS The author presents the largest series to date of 24 patients with multiloculated hydrocephalus who were treated endoscopically. The group included 10 boys and 14 girls with a mean age of 12.5 months. Uniloculated hydrocephalus was not included in this study because it is a different entity that would be better studied separately. RESULTS Neonatal meningitis was the most common cause (in 9 patients), followed by intraventricular hemorrhage (in 6 patients), postoperative gliosis (in 6 patients), and multiple neuroepithelial cysts (in 3 patients). Multiplanar magnetic resonance images made early diagnosis possible and are indicated if the computed tomography scan shows disproportionate hydrocephalus. Surgical treatment included ECF (in 24 patients), endoscopic revision of a malfunctioning preexisting shunt (in 6 patients), placement of a new shunt (in 15 patients), and third ventriculostomy (in 3 patients). The ECF was easily performed in all cases through devascularization of the cyst wall by coagulation to prevent recurrence. The results are encouraging with improvement of hydrocephalus in 18 patients (75%). The need for shunt insertion was avoided in 3 patients (12.5%). Endoscopy reduced shunt revision rate from 2.9 per year before fenestration to 0.2 per year after fenestration. During the overall mean follow-up period (30 months), repeated ECF was necessary in 8 patients (33%). Six (75%) of these 8 patients had already undergone shunt treatment before endoscopy. Endoscopic complications were minimal (2 cerebrospinal fluid leaks and 2 minor arterial hemorrhages), and there were no deaths (0%). CONCLUSIONS An ECF procedure is recommended in the treatment of multiloculated hydrocephalus because it is effective, simple, minimally invasive, and associated with low morbidity and mortality rates.

Abstract
BACKGROUND The management of intra- and paraventricular lesions is one of the fields in which modern neuroendoscopic techniques have given the most significant contribution in terms of reduction in operative invasiveness and postoperative complications. In this context, fluid cysts represent an ideal ground on which results obtained with traditional surgical procedures (open surgery, shunting) have more and more to compare with the increasing number of encouraging results obtained by neuroendoscopy. OBJECTIVE The objective of this study was to retrospectively evaluate the results of the endoscopic treatment of intra- and paraventricular cysts performed at our institution and how they compare with what has been reported in the literature, concerning the results of open surgery, shunting, and endoscopic management. MATERIALS AND METHODS All the patients with intra- and paraventricular cerebrospinal fluid (CSF) cysts endoscopically managed at our institution between March 2000 and October 2006 were included. Based on cyst location documented by magnetic resonance imaging (MRI), the cohort of patients examined was subdivided in five groups: A, paraventricular cysts; B, choroids plexuses cysts; C, secondary intraventricular cysts in previously hydrocephalus shunted patients; D, quadrigeminal cistern arachnoid cysts; and E, suprasellar arachnoid cysts. The neuroendoscopic procedures were performed with a 30 degrees rigid endoscope (Storz Decq, 3.8 mm). The surgical plan and best trajectory were selected on preoperative MR imaging. Postoperatively, all patients underwent CT scans in the first 48 h after surgery and MR control 3 months after surgery. RESULTS There were 26 patients (18 M/8F). The mean age at diagnosis was 8.95 years. Five of 26 cases were adult patients. Four patients had paraventricular cysts; 2 patients had a choroids plexuses cyst; 6 patients a secondary intraventricular cyst in previously shunted hydrocephalus; 11 patients had a quadrigeminal cistern arachnoid cyst and 3 patients had a suprasellar arachnoid cyst. Fifteen patients had an associated hydrocephalus at the time of the surgical treatment (one patient in group A, six patients in group C, six in group D, and two in group E). Twenty-three out of 26 patients underwent endoscopic management of their cystic lesion as primary procedure; in the remaining three cases, it represented a secondary procedure after open cyst marsupialization or/and the implant of a cystoperitoneal shunt. Endoscopic management consisted in a cystoventriculostomy (CV) in 19 patients. Third ventriculostomy (ETV) was associated to CV in seven cases, and it was performed at the same time of the CV procedure in all these cases. There was no mortality, neither operative morbidity. At a mean follow-up of 2.15 years (0.1-4 years), a complete resolution of preoperative clinical symptoms and signs was recorded in 80.9% of symptomatic patients. Control MRI showed a reduced cyst size in 25/26 patients and a stable cyst size in the last case, with signs of CSF flow between the cyst and the cerebral ventricles in all cases. One out of 15 patients with associated hydrocephalus had a persistent ventriculomegaly without signs of increased intracranial pressure. CONCLUSIONS Our results confirm that endoscopic management of intra- and paraventricular cysts is a valid alternative to open surgery as well as to shunting procedures. Control of clinical symptoms and signs was obtained in around 80% of our patients, while radiological evidence of cyst size reduction occurred in more than 95% of them. These rates are comparable with results of open surgery and shunting. The main advantage of neuroendoscopy is the low incidence of complications, a result that is confirmed by the present series.

Abstract
OBJECT The authors performed a retrospective analysis of data obtained in a series of 30 patients suffering from multiloculated hydrocephalus and treated endoscopically. The goal of the study was to evaluate the effectiveness of neuroendoscopic treatment as an alternative to the placement of multiple shunts to relieve intracranial hypertension, to simplify the shunt system, and to reduce the high rate of shunt revision. METHODS The endoscopic procedures included intraventricular septum fenestration, aqueductoplasty, Monro foraminoplasty, and third ventriculostomy. The patients were divided into two groups: Group A included 23 children in whom a shunt was already in place at the time of endoscopy, and Group B included seven children in whom a shunt had never been placed. The control of hydrocephalus by a single shunt placement or the absence of a shunt was achieved in 25 (83.3%) of 30 children. In Group A, five children no longer had shunts, 14 needed a single shunt, three required two shunts, and one required three shunts. The mean preendoscopy shunt revision rate in this group decreased from 2.07/year to 0.35/ year following the endoscopic procedure. Seven patients required endoscopic reoperations (endoscopic reoperation rate 0.31/year, total reoperation rate [shunt revisions plus endoscopic reoperation] 0.66/year). In Group B, three children did not require shunts, three needed a single shunt, and one required two shunts. Two patients required repeated endoscopic surgery (endoscopic reoperation rate 0.19/year), and two patients required shunt revisions (shunt revision rate 0.07/year) (total operation rate 0.26/year). CONCLUSIONS Neuroendoscopic procedures are a valid alternative to shunt revision in the management of multiloculated hydrocephalus. Early diagnosis comprising close monitoring with high-resolution magnetic resonance imaging and early treatment are the keys of success.

Abstract
OBJECT Endoscopic aqueductal stent therapy has evolved into an important technique in the treatment of a trapped fourth ventricle (TFV). The authors analyzed five cases of symptomatic TFV treated by endoscopic aqueductal stent therapy and, on the basis of intraoperative findings, discuss aspects of TFV formation. METHODS Patients' ages ranged from 2 to 17 years (mean 9.2 years). Two patients underwent endoscopy via a coronal bur hole approach and three via a small suboccipital craniectomy. The mean follow-up period was 30 months (range 24-38 months). In four cases, a membrane occluding the orifice of the aqueduct and covering part of the walls of the ventricle was observed. Despite slit ventricles in four cases, there was no intraoperative evidence of aqueduct wall collapse. All procedures were successful, and all patients experienced positive outcomes. In one patient, Parinaud syndrome, rotatory nystagmus, and abducent nerve palsy developed postoperatively; these deficits resolved after a preexisting supratentorial shunt was upgraded. There were no cases of aqueduct reocclusion during the follow-up period. CONCLUSIONS Aqueductal stent therapy is an effective method of TFV treatment. Because it prevents aqueduct reocclusion by chronic inflammatory processes in postinflammatory hydrocephalus, it has been shown to be more efficient than aqueductoplasty alone and to be an important alternative to the placement of a fourth ventricle shunt. Intraventricular processes leading to membrane formation play an important role in occlusion of the cerebral aqueduct orifices and final isolation of the fourth ventricle in postinflammatory hydrocephalus.

Abstract
Abstract
OBJECTIVE:
To assess the treatment of progressive multiloculated hydrocephalus by craniotomy for microsurgical fenestration of cerebrospinal fluid (CSF) compartments to minimize the number of ventricular catheters.
METHODS:
We studied 33 pediatric patients who underwent craniotomies for fenestration of progressive multiloculated hydrocephalus between 1989 and 2003. In 20 of 33 patients, hydrocephalus was attributed to intraventricular hemorrhage associated with prematurity. Twenty-three of 33 patients had previous central nervous system infections. Craniotomy was typically performed via a posterior parietal approach. Communication between bilateral supratentorial loculated compartments and posterior fossa compartments was achieved. Surgical and neurological outcomes were assessed.
RESULTS:
Fenestration of loculated CSF spaces was performed successfully in all patients. No new neurological deficits were noted after surgery, and no patients required intraoperative blood transfusions. CSF infections within 3 months after surgery occurred in 4 of 33 patients. Over a median follow-up period of 3.7 years (range, 1.5 mo to 8.7 yr), 19 of 33 patients required additional fenestration procedures. The number of repeat fenestration procedures ranged from one to six, and a total of 47 additional fenestrations were performed in these 19 patients. The majority of patients (n = 25) ultimately required shunt systems with only one ventricular catheter. The neurological status of these patients was extremely poor both before and after surgery. Twenty-nine of 33 patients were severely delayed, and four were mildly delayed.
CONCLUSION:
Fenestration of multiloculated CSF compartments can enable most patients to function with a single ventricular catheter shunt system. Neurological status remains poor in this patient population.

Abstract
Multilocular hydrocephalus is a complication of neonatal hydrocephalus. Its main feature is the presence of multiple cysts inside the ventricles, which requires a specific therapeutic approach. The case of a preterm infant with intracranial hemorrhage grade II-III and central nervous system infection is reported. The cysts developed at the subependymal layer in the posterior area of the patient's thalamus. Their growth and development were charted by ultrasound imaging for several weeks. These types of cysts may grow to occupy the totality of the lateral ventricles, isolating the temporal horns. Of all the reviewed pathogenic mechanisms, we support the hypothesis of an inflammatory vasculitis at the subependymal level, with the subsequent infarct giving rise to the cysts. The osmotic pressure within the cavities, rather than intraventricular fluid, would account for the enlargement of the cysts.

Abstract
In recent years endoscopic procedures have been used more frequently to treat loculated hydrocephalus. The trapped temporal horn, a specific type of loculation, has traditionally been treated by means of ventricular shunt placement. By opening up loculations, however, this procedure can be simplified or, in some cases, even avoided. In this report the author discusses a case of trapped temporal horn that was caused by fungal meningitis and treated using endoscopically guided fenestration of the choroidal fissure, leading to clinical and radiographic resolution of the syndrome. Using this simple procedure allows the surgeon to take advantage of normal temporal horn anatomy and landmarks, avoiding the scarred and distorted region of ventricular obstruction.

Abstract
This study is an attempt to establish that CSF shunt infection has a role in the aetiology of multiloculated hydrocephalus. The authors carried out a review of 12 cases of multiloculated hydrocephalus who were treated at King Khalid University Hospital between 1988-1994. The multiloculation appears to have developed following the shunt infection in all cases. The hydrocephalus was related to an intraventricular haemorrhage (IVH) in 9 patients and was congenital in 2 patients and post-meningitic in 1 patient. The shunt infection was caused by a gram-negative organism in 8 patients and duration of external ventricular drainage ranged from 9-24 (median 13) days. The diagnosis of multiloculated hydrocephalus was made on average 2 months after the shunt infection. In three patients endoscopic fenestration of intraventricular septations was attempted but was effective in only one case. The other patients were managed by two shunts (9 patients) and three shunts (2 patients). At a mean follow-up of 15 months, the shunt revision rate of the patients was 0.4/year. One patient died of multiple brain abscesses and 6 patients remain severely disabled. The poor outcome may also be related to the original IVH as well as the multiloculated hydrocephalus. The study also shows that patients with post-haemorrhagic hydrocephalus, who develop a shunt infection due to gram-negative organisms and in whom the CSF fails to be cleared of the infection following 12 days of external drainage appear to be at risk of developing multiloculated hydrocephalus.

Abstract
Loculated hydrocephalus remains a difficult neurosurgical problem and endoscopes designed to navigate through the ventricular system provide a new option for treatment. The authors review their experience, during the period March 1990 to June 1993, using a steerable fiberscope in 34 cases of loculated hydrocephalus to evaluate the efficacy of endoscopic cyst fenestration. The goals of treatment were to control hydrocephalus, simplify preexisting shunt systems, and reduce operative morbidity. Endoscopic cyst fenestrations reduced the shunt revision rate from 3.04 per year prior to endoscopy to 0.25 per year after the procedure, during a follow-up period ranging from 8 to 45 months, mean 26 months. However, eight patients (23.5%) required 14 repeat operations to control loculated hydrocephalus. After endoscopy, patients with multiloculated hydrocephalus had a nearly fivefold increased risk (relative risk 4.85) for shunt malfunction and more than a twofold increased risk (relative risk 2.43) for cyst recurrence versus patients with uniloculated hydrocephalus. Similarly, six (50%) of 12 patients shunted prior to endoscopy required a repeat endoscopic procedure (relative risk 5.56). Although repeat endoscopic procedures may be required to control hydrocephalus, endoscopic cyst fenestration avoided placement of a shunt in seven (33%) of 21 patients with uniloculated hydrocephalus. One patient, encountered early in the authors' experience, required a craniotomy for fenestration of multiple ventricular cysts. Endoscopic complications included cerebrospinal fluid leakage in one case and ventriculitis in another. The authors conclude that endoscopic treatment of loculated hydrocephalus is a safe, minimally invasive technique that should be considered as the initial treatment option.
