Slit Ventricle Syndrome

Sung Min Cho, Dong Ha Park, Soo Han Yoon
OBJECTIVE: The recently developed new direct gradual cranial expansion surgical technique has been applied to the treatment of children with post-shunt microcephaly and slit ventricle syndromes. Therefore, we aim to study the intracranial pressure (ICP) in microcephalic children with developmental delay to evaluate the possibility of this new surgical treatment. METHODS: Twenty four microcephalic children with developmental delay who had had continuous ICP monitoring were compared with respect to mean ICP, age, gender, head size, and developmental assessments...

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...

BACKGROUND: Overshunting-associated myelopathy (OSAM) is a very rare complication of ventricular shunt therapy, and only 11 previous cases have been reported in the literature. We report the successful surgical management of a case of OSAM in a patient with bilateral jugular vein occlusion and congenital hydrocephalus. CASE DESCRIPTION: A 45-year-old patient with shunt-dependent, congenital hydrocephalus presented to our department with an 8-year history of progressive tetraparesis and gait disturbance...

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...

BACKGROUND: Craniosynostosis is an uncommon complication after shunting procedures for congenital hydrocephalus. We report a case of a child with myelomeningocele and normocephaly at the time of birth. She underwent ventricular shunting for Chiari malformation and hydrocephalus at 3 days of age. An immediate postoperative CT scan confirmed all sutures were open. Serial CT scans document an open metopic suture at 2 months, closed metopic suture at 5 months, and trigonocephaly at 11 months with concomitant slit ventricle syndrome, and collapsed lateral and third ventricles...

Endoscopic third ventriculostomy (ETV) is increasingly used in place of shunt revision for shunt malfunction (secondary ETV). This review provides a comprehensive overview of preoperative, operative and postoperative considerations for patients undergoing a secondary ETV. Preoperatively, patient selection is vital and there is evidence that secondary ETV is more effective than primary ETV in certain hydrocephalic aetiologies. Operative considerations include use of neuronavigation and consideration of surgeon technical experience due to anatomical differences that are likely to accompany chronic shunting, management of existing shunt hardware and the use of temporary external ventricular drains or short/long-term ventricular access devices...

The present study aimed to investigate the efficacy of endoscopy in the treatment of post-shunt placement for slit ventricle syndrome (SVS). Endoscopic surgery was performed on 18 patients with SVS between October 2004 and December 2012. Sex, age, causes of the hydrocephalus, ventricular size and imaging data were collected and analyzed. All patients were divided into two groups according to ventricular size and underwent endoscopic surgeries, including endoscopic third ventriculostomy (ETV), endoscopic aqueductoplasty and cystocisternostomy...

BACKGROUND: Hypoplastic left heart syndrome (HLHS) covers a spectrum of rare congenital anomalies characterised by a non-apex forming left ventricle and stenosis/atresia of the mitral and aortic valves. Despite many studies, the causes of HLHS remain unclear and there are conflicting views regarding the role of flow, valvar or myocardial abnormalities in its pathogenesis, all of which were proposed prior to the description of the second heart field. Our aim was to re-evaluate the patterns of malformation in HLHS in relation to recognised cardiac progenitor populations, with a view to providing aetiologically useful sub-groupings for genomic studies...

The brain ventricular system (BVS) consists of brain ventricles and channels connecting ventricles filled with cerebrospinal fluid (CSF). The disturbance of CSF flow has been linked to neurodegenerative disease including hydrocephalus, which manifests itself as an abnormal expansion of BVS. This relatively common developmental disorder has been observed in human and domesticated animals and linked to functional deficiency of various cells lineages facing BVS, including the choroid plexus or ependymal cells that generate CSF or the ciliated cells that cilia beating generates CSF flow...

OBJECTIVE The authors conducted a survey to evaluate differences in the understanding and management of shunt-dependent hydrocephalus among members of the American Society of Pediatric Neurosurgeons (ASPN). METHODS Surveys were sent to all 204 active ASPN members in September 2014. One hundred thirty responses were received, representing a 64% response rate. Respondents were asked 13 multiple-choice and free-response questions regarding 4 fundamental problems encountered in shunted-hydrocephalus management: shunt malfunction, chronic cerebrospinal fluid (CSF) overdrainage, chronic headaches, and slit ventricle syndrome (SVS)...

Slit ventricle syndrome (SVS) is a well-known chronic complication of ventriculoperitoneal shunt (VPS) placement. In this report, we describe a unique anatomical change that we observed on the magnetic resonance (MR) images of the brain acquired from a patient with SVS. The patient was a 40-year-old woman who had undergone VPS placement at 3 months of age. A computed tomography scan of her brain revealed a slit-like ventricle. In addition, an MR image of her brain revealed upward ballooning of the third ventricle floor, which returned to normal after a lumbar puncture...

BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) and posterior reversible encephalopathy syndrome (PRES) are both rare disorders. The pathophysiology of both diseases is not yet fully understood. METHODS: We report the unique case of a 19-year-old comatose woman who was brought to the ER after a series of generalized tonic-clonic seizures 6 days post peridural anesthesia for cesarean section. Vital signs and initial laboratory testing including urine analysis and drug screening were unremarkable...

Circulating dipeptidyl peptidase IV (DPPIV) activity is associated with worse cardiovascular outcomes in humans and experimental heart failure (HF) models, suggesting that DPPIV may play a role in the pathophysiology of this syndrome. Renal dysfunction is one of the key features of HF, but it remains to be determined whether DPPIV inhibitors are capable of improving cardiorenal function after the onset of HF. Therefore, the present study aimed to test the hypothesis that DPPIV inhibition by vildagliptin improves renal water and salt handling and exerts anti-proteinuric effects in rats with established HF...

Slit-ventricle syndrome (SVS) seems to encompass various pathophysiological abnormalities, including overdrainage of cerebrospinal fluid (CSF) and craniocerebral disproportion after extracranial CSF shunt placement. These pathologies result in small ventricle morphologically, and the ventricular catheter is obstructed by the collapsed ventricular walls. Patients with intermittent headaches, small ventricles on neuroimaging, and slow refill of the shunt reservoir are diagnosed with SVS. In this report, we present a case of SVS treated endoscopically...

Normal pressure hydrocephalus (NPH) is characterized by the triad of gait apraxia, dementia and urinary incontinence associated with ventriculomegaly and normal pressure of cerebrospinal fluid. Treatment is accomplished through the implantation of a ventricular shunt (VPS), however some complications are still frequent, like overdrainage due to siphon effect. This study analyses the performance of a valve with anti-siphon device (SPHERA®) in the treatment of patients with NPH and compares it with another group of patients with NPH who underwent the same procedure without anti-siphon mechanism (PS Medical® valve)...

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...

INTRODUCTION: Levodopa-responsive parkinsonism has been reported following ventriculoperitoneal (VP) shunt in patients with obstructive hydrocephalus due to aqueductal stenosis. It has been thought to arise from injury to the global rostral midbrain including the nigrostriatal pathway by a transtentorial pressure gradient. We present a similar patient, but his parkinsonism resisted levodopa administration during the initial therapy. CASE REPORT: A 51-year-old man suffered from hydrocephalus due to secondary aqueductal stenosis presumably attributed to massive bleeding during surgery for a fourth ventricle hemangioblastoma...

Hypoplastic left heart syndrome (HLHS) is a severe congenital heart defect (CHD) that necessitates staged, single ventricle surgical palliation. An increased frequency of bicuspid aortic valve (BAV) has been observed among relatives. We postulated number of mutant alleles as a molecular basis for variable CHD expression in an extended family comprised of an HLHS proband and four family members who underwent echocardiography and whole-genome sequencing (WGS). Dermal fibroblast-derived induced pluripotent stem cells (iPSC) were procured from the proband-parent trio and bioengineered into cardiomyocytes...

PURPOSE: Defective posterior spinal arch and paraspinal musculature lead to progressive kyphosis in patients with myelomeningocele. Kyphosis decreases the patients' functional status and quality of life. To correct or prevent further deterioration, different surgical techniques have been introduced. Our aim is to present our clinical experience in kyphectomy and pedicle screw fixation with a posterior-only approach in pediatric patients with myelomeningocele and to discuss the technique with a review of the literature...
