Chronic Pediatric Headache as a Manifestation of Shunt Over-Drainage and Slit Ventricle Syndrome in Patients Harboring a Cerebrospinal Fluid Diversion System: A Narrative Literature Review. CHILDREN (BASEL, SWITZERLAND) 2024; 11:596. [PMID: 38790591 PMCID: PMC11120100 DOI: 10.3390/children11050596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 04/19/2024] [Accepted: 05/13/2024] [Indexed: 05/26/2024]
Abstract
The main subject of the current review is a specific subtype of headache, which is related to shunt over-drainage and slit ventricle syndrome, in pediatric patients harboring an implanted shunt device for the management of hydrocephalus. This clinical entity, along with its impairment regarding the quality of life of the affected individuals, is generally underestimated. This is partly due to the absence of universally agreed-upon diagnostic criteria, as well as due to a misunderstanding of the interactions among the implicated pathophysiological mechanisms. A lot of attempts have been performed to propose an integrative model, aiming at the determination of all the offending mechanisms of the shunt over-drainage syndrome, as well as the determination of all the clinical characteristics and related symptomatology that accompany these secondary headaches. This subcategory of headache, named postural dependent headache, can be associated with nausea, vomiting, and/or radiological signs of slim ventricles and/or subdural collections. The ultimate goal of our review is to draw clinicians' attention, especially that of those that are managing pediatric patients with permanent, long-standing, ventriculoperitoneal, or, less commonly, ventriculoatrial shunts. We attempted to elucidate all clinical and neurological characteristics that are inherently related to this type of headache, as well as to highlight the current management options. This specific subgroup of patients may eventually suffer from severe, intractable headaches, which may negatively impair their quality of daily living. In the absence of any other clinical condition that could be incriminated as the cause of the headache, shunt over-drainage should not be overlooked. On the contrary, it should be seriously taken into consideration, and its management should be added to the therapeutic armamentarium of such cases, which are difficult to be handled.

World Neurosurg X 2023; 19:100195. [PMID: 37151993 PMCID: PMC10160597 DOI: 10.1016/j.wnsx.2023.100195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 04/09/2023] [Accepted: 04/11/2023] [Indexed: 05/09/2023] Open
Abstract
Objective Symptomatic intracranial arachnoid cysts (ACs) should be treated either through microsurgical (MS) or endoscopic surgical (ES) fenestration. Implantation of cysto-peritoneal shunt (CPS) system is another treatment option with decreasing indication. In our study, we compared the complication and revision rates between the three operative techniques in pediatric patients. Methods We included patients below 18 years with symptomatic intracranial ACs operated between 2004 and 2021. Initial symptoms, location, complication rate, clinical and radiological improvement, postoperative events and revision rate were compared retrospectively. Results Sixty-one patients; 33 (54.1%) MS operated (mean age 7.6 years), 18 (29.5%) ES operated (mean age 6.2 years) and 10 (16.4%) with CPS (mean age 3.0 years) were collected. The most common initial symptom was headache in 45.9%. 20 (32.8%) postoperative events were documented. The highest revision rate (60%) was seen in the CPS group compared to 33.3% in MS group and 16.7% in ES group. 31 patients harbored perisylvian ACs, 89% remained event-free after ES, 71% after MS and 20% after CPS. Clinical improvement immediately after surgery was observed in 58 patients (96.9% in MS, 88.9% in ES and 100% in CPS). A radiological volume reduction could be proven postoperative in 51 patients (78.8% MS, 88.9% ES and 90% CPS). Conclusion Endoscopic fenestration of AC is a safe and efficient technique which is being widely used nowadays with the highest event free survival compared to microsurgical fenestration especially in perisylvian arachnoid cysts. CPS shows on long terms the highest revision rate but carries the least surgical risks.

Abstract
INTRODUCTION A dermal sinus tract (DST) is an uncommon type of spinal dysraphisms characterized by a tract lined with stratified squamous epithelium that extends from the subcutaneous tissue to the underlying thecal sac or neural tube. These developmental anomalies can present asymptomatically with cutaneous abnormalities or with devastating complications. Usually, it is presented as a unique lesion, and there are only a few reports that show multiple sinuses, and none of them associated with midline brain malformations. METHODS We present the case of a 3-day-old girl with an antenatal diagnosis of hydrocephalus who was diagnosed with double dermal sinus tracts of the cervical and thoracic regions at admission. The patient presented signs of elevated intracranial pressure (ICP), which imposed a challenge in the management of the case. RESULTS Our patient was successfully treated initially with a lumbar puncture in order to discard a cerebrospinal fluid (CSF) infection. With negative CSF cultures, a ventriculoperitoneal shunt (VPS) was placed. Nine days after the VPS surgery and without signs of infection, the DST was excised in a single procedure, without follow-up complications. CONCLUSION To our knowledge, this is the first description of a patient with multiple midline neural tube defects (NTDs) associated with congenital intracranial pathology. Although there are no guidelines regarding the best treatment for this complex associated pathology, the patient was treated, without follow-up complications.

External-internal cranial expansion to treat patients with craniocerebral disproportion due to post-shunt craniosynostosis: a case series. Childs Nerv Syst 2022; 39:953-961.

Abstract
INTRODUCTION Secondary craniosynostosis subsequent to shunting is one of the late complications of ventricular shunt placement in the early childhood. Several interventions have been used to treat high intracranial pressure associated with this condition. This study aimed to evaluate the patients' clinical symptoms and head circumference before and after a method of decompressive craniotomy, coined as external-internal cranial expansion (EICE). METHODS A retrospective study was conducted, and the patients who had undergone EICE for the treatment of post-shunt craniosynostosis between 2010 and 2020 were enrolled. This approach was a combination of a hinge multiple-strut decompressive craniectomy and internal cranial flap thinning by drill. Data, extracted from medical records, were used to evaluate the patients' symptoms and head circumferences before and 12 months after surgery. RESULTS A total of 16 patients were enrolled in the study, of which eight were females. Before the surgery, 9 patients (56.2%) suffered from visual impairment, and all had intractable headache. Papilledema was recorded in all, with 3 cases having optic disc paleness. After cranial expansion, only two patients had headaches, diagnosed as migraine-type and psychosomatic headaches, respectively. In two patients, progressive visual impairments got worsening after surgery, which would be due to severe preoperative optic nerve atrophy. Patients' head circumferences significantly increased after the surgery (mean of 48.97 ± 4.28 cm vs. 45.78 ± 4.31 cm; P value < 0.0001). CONCLUSION In lower resource countries, where newer technologies like distraction osteogenesis is not easily available, external-internal cranial expansion can be considered an effective alternative for patients with post-shunt craniosynostosis.

Abstract
OBJECTIVE Slit ventricle syndrome (SVS) is an iatrogenic disease occurring in patients with ventriculoperitoneal shunt. This article reports the management modalities and results in a case series from a single center. METHODS We reviewed a series 48 hospitalized patients with severe SVS whom we managed in a 10-year period. Thirty-seven patients harboring programmable valves (P-valves) first underwent attempts at valve reprogramming. This treatment produced no effect in 21 patients, who therefore required surgical treatment. Surgery was also required by 11 patients without P-valve. Accordingly, 32 patients had to be operatively treated by shunt externalization followed by valve replacement or endoscopic third ventriculostomy basing on intracranial pressure and ventricular size. The new valve was either ProGav Mietke (Aesculap) or Medos Codman (Integra), each equipped with its own antisiphon system. In selected cases, a programmable antisiphon system (ProSa Mietke) was used. RESULTS Surgical mortality was 3% and major morbidity accounted for 6%. Complete resolution was obtained in 55% of cases, improvement in 32%, and no effect or worsening in 13%. Only 1 patient became shunt free after endoscopic third ventriculostomy. Medos and ProGrav provided comparable outcomes, whereas ProSa was determinant in selected cases. Pediatric age, uncomplicated shunt courses, and short SVS histories were significantly favorable indicators. CONCLUSIONS SVS management remains problematic. However, this study individuated factors that may improve the outcome, such as wider use of P-valves to treat hydrocephalus, timely diagnosis of overdrainage, and earlier and more aggressive indications to manage SVS.

Abstract
BACKGROUND Craniosynostosis following placement of a ventriculoperitoneal shunt for hydrocephalus has been sporadically described. The purpose of this investigation was to determine the general risk of developing craniosynostosis in this patient population. METHODS The authors retrospectively reviewed records and radiographs of infants who underwent ventriculoperitoneal shunt placement for hydrocephalus from 2006 to 2012. Recorded variables included date of shunt placement, demographics, comorbidities, cause of hydrocephalus, shunt type, and number of shunt revisions. Axial computed tomographic images obtained before and immediately after shunt placement and 2 to 4 years after shunt placement were evaluated by a panel of clinicians for evidence of craniosynostosis. Patients with preshunt craniosynostosis, craniosynostosis syndromes, or poor-quality computed tomographic images were excluded. Data were analyzed using STATA Version 15.1 statistical software. RESULTS One hundred twenty-five patients (69 male and 56 female patients) were included. Average age at shunt placement was 2.3 ± 2.58 months. Sixty-one patients (48.8 percent) developed craniosynostosis at a median of 26 months after shunt placement. Of these, 28 patients fused one suture; the majority involved the sagittal suture (n = 25). Thirty-three patients fused multiple sutures; the most common were the coronal (n = 32) and the sagittal (n = 30) sutures. Multivariable logistic regression identified older age at shunt placement and more shunt revisions as independent predictors of craniosynostosis. Shunt valve type was not significant. CONCLUSIONS Craniosynostosis developed in nearly half of infants who underwent ventriculoperitoneal shunt placement for hydrocephalus. The sagittal suture was most commonly involved. The effect of suture fusion on subsequent cranial growth, shunt failure, or the development of intracranial pressure is unclear. CLINICAL QUESITON/LEVEL OF EVIDENCE Risk, III.

Abstract
INTRODUCTION An isolated fourth ventricle (IFV) is a rare entity observed in shunted patients and its treatment is still uncertain. Endoscopic aqueductoplasty has shown good results for restoring CSF flux between the third and fourth ventricles. However, it needs some grade of ventricular dilation to be performed. Some patients affected by IFV show slit-ventricle morphology in CT/MRI. Usually, the rise of opening pressure or the shunt externalization gets enough ventricular dilation. However, the lack of intracranial compliance in some patients makes these options unsuitable and high-ICP symptoms are developed without ventricular dilation. METHODS We present a two cases series affected by IFV with no ventricular dilation in radiological exams. ICP sensors were implanted, observing high-ICP and establishing the diagnosis of craniocerebral disproportion. A two-stage surgical plan based on a dynamic cranial expansion followed by a supratentorial endoscopic aqueductoplasty was performed. A physical and mathematical model explaining our approach was also provided. RESULTS Chess-table cranial expansion technique was performed in both patients. Six/seven days after the first surgery, respectively, ventricular dilation was observed in CT. Endoscopic precoronal aqueductoplasty was then performed. No postoperative complications were described. IFV symptoms improved in both patients. Eighteen and 12 months after the two-stage surgical plan, the patients remain symptom-free and void of flow is still observed between the third and the fourth ventricles in MRI. CONCLUSION The two-stage approach was a suitable option for the treatment of these complex patients affected by both craniocerebral disproportion and isolated fourth ventricle.

Abstract
INTRODUCTION While cases of acquired Chiari I malformation following ventriculoperitoneal shunting for posthemorrhagic hydrocephalus have been reported, true disproportionate cerebellar growth is rare, with no previous cases requiring posterior fossa decompression reported. CLINICAL PRESENTATION We present a premature neonate who underwent ventriculoperitoneal shunt placement for suspected posthemorrhagic hydrocephalus. He subsequently developed a symptomatic Chiari I malformation with volumetric measurements demonstrating disproportionate growth of the cerebellum. He did not demonstrate thickening of the supratentorial or posterior fossa cranium. The patient underwent an extradural posterior fossa decompression, with resolution of symptoms. OUTCOME AND CONCLUSIONS We review the extant literature regarding the development of Chiari malformation type I as a manifestation of craniocerebral disproportion (CCD) following shunt placement for posthemorrhagic hydrocephalus of prematurity. Most previous reports reflect a mechanism that includes underdevelopment of the intracranial posterior fossa (or supratentorial) volume. The case presented in this report, as well as one additional case, indicates that there may exist a variant mechanism, characterized by rapid growth of the cerebellum itself, in the absence of one of the rare syndromes associated with primary macrocerebellum. While this case was effectively managed with extradural posterior fossa decompression, previous reports indicate that supratentorial cranial expansion procedures are preferable in some cases. As such, pediatric neurosurgeons should be able to distinguish the patterns of craniocerebral disproportion when considering treatment options for these patients. Further investigation regarding these uncommon patients may better describe the underlying mechanisms.

Abstract
Ventricular shunting procedures represent the classical surgical treatment for hydrocephalus. Slit ventricle syndrome (SVS) with craniocerebral disproportion (CCD) and secondary craniosynostosis (SCS) is a well-known but uncommon complication following cerebrospinal fluid (CSF) shunting in children. Its general management includes shunt upgrade or revision, placement of anti-siphon devices, lumbo-peritoneal shunting, and endoscopic third ventriculostomy. Cranial expansion is generally considered a major procedure and is indicated when less invasive treatments fail. In these cases, SVS and associated SCS have been usually managed through anterior cranial vault expansion. This procedure aims to decrease the risk of further shunt revisions and to improve neurologic symptoms, but it takes the disadvantage of considerable iatrogenic alterations of the facial proportions. The authors report a case of a 6-year old boy with SVS and SCS, who maintained eumorphic face and was treated by an innovative post-coronal vault expansion ensuring a wide volume increase while avoiding any change of facial conformation.

Abstract
INTRODUCTION Craniocerebral disproportion (CCD) can occur as a sequela after shunting in early infancy. It can be understood as a disorder closely related to slit ventricle syndrome and chronic overdrainage syndrome. Here, we present two exemplary cases and summarize the pathophysiological, diagnostic, and therapeutic approaches to CCD. CLINICAL PRESENTATION Two premature babies underwent shunting for posthemorrhagic hydrocephalus and presented in later childhood with recurrent episodes of symptomatic raised intracranial pressure (ICP) at 2 and 8 years of age, respectively. DIAGNOSIS AND MANAGEMENT Both patients had unchanged ventricular size on cranial imaging and fulfilled the clinical diagnostic criteria of CCD. After confirming shunt patency, ICP monitoring was performed to diagnose intermittent intracranial hypertension. Different treatment pathways were pursued: While readjustment of a programmable shunt valve was sufficient to alleviate the raised ICP in the first case, a cranial expansion surgery was necessary in the second case. OUTCOME AND CONCLUSIONS Both children were treated successfully after thorough assessment and careful choice of treatment approaches. This review provides detailed insight into CCD and highlights the importance of individual and critical decision-making in these complex patients.

Abstract
OBJECTIVEThe object of this study was to use diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS) to characterize the long-term effects of hydrocephalus and shunting on white matter integrity and to investigate the relationship of ventricular size and alterations in white matter integrity with headache and quality-of-life outcome measures.METHODSPatients with shunt-treated hydrocephalus and age- and sex-matched healthy controls were recruited into the study and underwent anatomical and DTI imaging on a 3-T MRI scanner. All patients were clinically stable, had undergone CSF shunt placement before 2 years of age, and had a documented history of complaints of headaches. Outcome was scored based on the Headache Disability Inventory and the Hydrocephalus Outcome Questionnaire. Fractional anisotropy (FA) and other DTI-based measures (axial, radial, and mean diffusivity; AD, RD, and MD, respectively) were extracted in the corpus callosum and internal capsule with manual region-of-interest delineation and in other regions with TBSS. Paired t-tests, corrected with a 5% false discovery rate, were used to identify regions with significant differences between patients and controls. Within the patient group, linear regression models were used to investigate the relationship between FA or ventricular volume and outcome, as well as the effect of shunt-related covariates.RESULTSTwenty-one hydrocephalus patients and 21 matched controls completed the study, and their data were used in the final analysis. The authors found significantly lower FA for patients than for controls in 20 of the 48 regions, mostly posterior white matter structures, in periventricular as well as more distal tracts. Of these 20 regions, 17 demonstrated increased RD, while only 5 showed increased MD and 3 showed decreased AD. No areas of increased FA were observed. Higher FA in specific periventricular white matter tracts, tending toward FA in controls, was associated with increased ventricular size, as well as improved clinical outcome.CONCLUSIONSThe study shows that TBSS-based DTI is a sensitive technique for elucidating changes in white matter structures due to hydrocephalus and chronic CSF shunting and provides preliminary evidence that DTI may be a valuable tool for tailoring shunt procedures to monitor ventricular size following shunting and achieve optimal outcome, as well as for guiding the development of alternate therapies for hydrocephalus.

Abstract
OBJECTIVE Craniocerebral disproportion (CCD) is a challenging disease, and several expansile procedures have been used for its treatment. This report describes the dynamic chess-table cranial expansion technique and reports on 9 patients with primary and secondary CCD treated with this procedure. METHODS Nine patients affected by CCD were treated with chess-table cranial expansion and reviewed. Symptoms of increased intracranial pressure (ICP) and radiologic findings were analyzed. ICP was monitored using epidural or telemetric sensors. Intracranial volume was measured using computed tomography image processing tools before the surgery, 24 hours after the surgery, and 1 month later. A mathematical model was developed to explain the clinical and surgical results. RESULTS Five patients had secondary CCD and 4 had primary CCD. The mean age for cranial expansion was 16.78 years. The most frequent symptoms were headaches, nausea/vomiting, and decreased consciousness. Slit ventricles and sutural sclerosis were observed in 33.3% and 55.6% of patients. The mean ICP before the procedure was 48.67 mm Hg. Progressive cranial expansion was seen in all patients after surgery. The mean ICP decreased to 11 mm Hg and mean intracranial volume expansion was 85.8 cm3 at 1 month after surgery. There were no serious complications after surgery. All patients improved their symptoms, and no patient needed additional cranial expansion procedures. CONCLUSIONS Chess-table cranial expansion is a safe and effective procedure and may be used as an alternative treatment for CCD. Progressive expansion of the intracranial volume is related to a decrease in ICP recordings and an improvement of symptoms.

Abstract
BACKGROUND AND IMPORTANCE Extensive cerebral resections for the treatment of epilepsy may result in a large intracranial dead space that is prone to recurrent hemorrhage, either due to mechanical dislodgement or the development of extensive subdural membranes. Several techniques have been proposed to decrease the risk of hemorrhage by either reducing or filling the remaining intracranial dead space. CLINICAL PRESENTATION We present a case of persistent hemorrhage following functional hemispherectomy in a patient with a large porencephalic cyst. A treatment strategy involving both subdural space reduction and cranial vault filling with a vascularized free latissimus dorsi flap is discussed. CONCLUSION Subdural space reduction and cranial vault filling with a vascularized free latissimus dorsi flap is a viable treatment alternative in patients with large areas of intracranial dead space.

Surgical management of craniosynostosis in the setting of a ventricular shunt: a case series and treatment algorithm. Childs Nerv Syst 2018; 34:517-525.

Abstract
PURPOSE Cerebrospinal fluid diversion via ventricular shunt is a common treatment for hydrocephalus. Change in cranial morphology associated with a sutural fusion has been termed shunt-related or induced craniosynostosis (SRC) or craniocerebral disproportion (CCD). We present a series of patients with SRC who underwent cranial vault remodeling (CVR) and our treatment algorithm. METHODS Thirteen patients were retrospectively reviewed who had SRC and CVR; 92% of patients had a ventriculoperitoneal (VP) shunt placed for largely intraventricular hemorrhage of prematurity (69% of patients) at a mean age of 2.2 months. The shunt revision rate was 38.4%, and 54% of patients had a programmable shunt placed initially. RESULTS The mean age at time of CVR was 3.6 years old. The most commonly affected sutures (CT confirmed) were the sagittal and coronal sutures, with three patients exhibiting pancraniosynostosis. The mean time from placement of the shunt to CT evidence of sutural fusion was 2.0 years. Abnormal head shape was noted in all 13 patients; 11 of these also had either chronic headaches, papilledema, seizures, or behavioral changes in the setting of functional shunt. Mean follow-up after the initial CVR was 3.3 years. No shunt infections were attributed to the CVR. The families of all patients were contacted and reported improvement in head shape with 60% of families reporting improvement in behavior, 75% reported improvement in headaches, and 40% reported decrease in seizure frequency or intensity. Shunt setting or type was not routinely changed after CVR. CONCLUSIONS Our threshold for CVR in SRC is met when shunt malfunction has been ruled out and there are (1) radiographic evidence of craniosynostosis, (2) signs of increased ICP clinically or radiographically, and (3) cranial dysmorphism, i.e., dolichocephaly. The majority of cases of SRC result in improved cranial morphology in addition to some abatement of the symptoms of increased intracranial pressure. Early involvement of an experienced craniofacial/neurosurgical team could allow for early diagnosis and intervention which may prevent progression to more severe deformities. SRC is a complex entity, with multiple etiologies, and a future study is needed.

Abstract
Craniocerebral disproportion is rarely considered as a cause for chronic, debilitating headache in adults. Children reported with this disorder typically suffer from headaches and lethargy for many years and have multisutural synostosis. The terms craniocerebral disproportion, craniostenosis, and slit-ventricle syndrome are used inconsistently as diagnostic designations. Three adults with craniocerebral disproportion who had been treated in infancy for two different pathologies are reported. All benefited greatly from cranial vault expansion.

Abstract
RATIONALE Shunt-induced craniosynostosis is one of the late complications of CSF shunting surgery, which affects the patient's condition, clinical picture, and treatment approach. OBJECTIVE to evaluate the prevalence rate and clinical significance of this disease, define the indications for surgery, and choose the optimal surgical approach. MATERIAL AND METHODS The study included 59 children with shunt system dysfunction, aged 1 to 14 years, who were treated at the Department in the period from 2014 to 2016. The inclusion criteria were as follows: 1) age at the time of examination is older than 1 year; 2) implantation of a shunt system in the first 12 months of life. The state of cranial sutures was assessed using three-dimensional reconstruction of patient's computerized tomography images. Images obtained before or in the first months after primary implantation of a shunt system were used to exclude cases of primary craniosynostosis. RESULTS Premature synostosis of the cranial sutures was detected in 27 (46%) cases. Of these, 3 (11%) patients with clinical symptoms of increased intracranial pressure and radiographic signs of craniocerebral disproportion underwent cranial vault remodeling surgery: two biparietal craniotomies and one fronto-parieto-occipital reconstruction. In two cases, simultaneous replacement of a valve with a programmable one was performed. There were no complications after reconstructive surgery. CONCLUSION Shunt-associated craniosynostosis is one of the late complications of CSF shunting surgery. However, its presence is not an indication for surgery and should not be a reason for surgical aggression. Surgery for increasing the intracranial volume is indicated only for secondary craniosynostosis combined with signs of craniocerebral disproportion. In these cases, reconstructive surgery is an effective treatment option for improving the patient's condition.

Abstract
INTRODUCTION Shunt-related craniosynostosis causing craniocerebral disproportion represents a particular complication of the treatment of hydrocephalus. When the modification of the shunt opening pressure does not improve the symptomatology, surgery for correction of craniocerebral disproportion is indicated. We present the results and advantages of the split bi-frontal bone technique that is a modification of the previous used frontal bone advancement technique. PATIENTS AND METHODS We retrospectively reviewed 5 patients with iatrogenic craniosynostosis treated in our institution from 1995 to 2012. A splitting bi-frontal bone flap that is left floating posteriorly was performed to increase the cranial volume. RESULTS All patients were cured. This technique increases the volume of the skull favoring the expansion of the brain and allows good cosmetical results. No perioperative complications were reported. DISCUSSION The fact that the brain has a more appropriate volume allows the disappearance of the clinical symptomatology related to the split ventricle syndrome. The advantage is the respect of the fronto-orbital shape in children and adults with the same results of the classic frontal advancement in terms of volume expansion. The study of cerebral blood flow confirms the increase of the cerebral blood perfusion and the improvement of the regional cerebral blood flow in borderline regions. We preconize, for the treatment of slit ventricle syndrome, the bi-frontal split technique in children and adults for its efficacy, the low rate of complications and the respect of aesthetical constraints.
