Abdominal CSF pseudocysts are an uncommon complication of ventriculo-peritoneal shunting. We report the case of a 35 year old man with a myelomenigocele, associated Chiari 2 malformation, and VP shunt developing a Diffuse Large B-Cell Lymphoma within the lining of an abdominal CSF pseuodcyst. This diagnosis should be considered in those with recurrent pseudocysts, or those associated with a swinging pyrexia and high C-Reactive protein, in the absence of infection.

Seeding of a central nervous system malignancy to the abdominal cavity is an uncommon but well documented complication of a ventriculoperitoneal (VP) shunt. However, the metastasis of a primary gastrointestinal cancer to the skin via a VP shunt is extremely rare. We report the clinical case of an 85-year-old male who presented with a right upper quadrant nodule over his shunt, which on histopathology and tumour marker profile was diagnosed as an adenocarcinoma of likely upper gastrointestinal origin. This case illustrates the importance of proceeding to biopsy to inform prognosis and management, despite the risks of shunt infection...

BACKGROUND: Ventriculoperitoneal (VP) shunt placement is one of the most commonly performed procedures in neurosurgery. One rare complication is the formation of an abdominal pseudocyst, which can cause shunt malfunction. CASE DESCRIPTIONS: We present four unique cases of abdominal pseudocyst formation. Our first patient initially presented with a right upper quadrant pseudocyst. Shunt was externalized and the distal end was revised with placement of catheter on the opposite side...

Bladder migration and transurethral extrusion is an extremely rare complication of ventriculoperitoneal (VP) shunt. Only eight cases have been reported in the English literature since 1995. We report a case of a 4-year-old boy with cerebral palsy, hydrocephalus, and VP shunted on both sides who presented with a protruded distal VP shunt from his urethral orifice. The patient was reported for having previous shunt extrusion through the anus. The patient was treated on by a multidisciplinary approach, involving a neurosurgeon and urologist...

Hydrocephalus is usually treated by placement of a ventriculo-peritoneal (VP) shunt. Distal VP shunt failure is a common complication of this procedure, especially in the paediatric population. Distal shunt revisions are often made more technically difficult by challenging abdominal anatomy. In this technical note, we describe a simple technique utilizing tenting sutures and the previous shunt tract for placement of the distal abdominal catheter accurately into the peritoneal space during distal shunt revision...

INTRODUCTION: Hydrocephalus represents impairment in cerebrospinal fluid (CSF) dynamics. If the treatment of hydrocephalus is considered difficult, the repeated revisions of ventriculo-peritoneal (VP) shunts are even more challenging. OBJECTIVE: The aim of this article is to evaluate the efficiency of ventriculo-epiplooic (VEp) shunt as a feasible alternative in hydrocephalic patients. MATERIAL AND METHODS: A technical modification regarding the insertion of peritoneal catheter was imagined: midline laparotomy 8-10cm long was performed in order to open the peritoneal cavity; the great omentum was dissected between its two layers; we placed the distal end of the catheter between the two epiplooic layers; a fenestration of 4cm in diameter into the visceral layer was also performed...

PURPOSE: Characterized by a progressive onset of gait disturbances, dementia, and urinary incontinence, idiopathic normal pressure hydrocephalus (iNPH) is considered a rare, but under-diagnosed disease. Non-invasive diagnostic markers are still insufficient to enable the diagnosis of iNPH with certainty and yet early treatment with ventriculoperitoneal (VP) shunting can reverse symptoms and stop disease progression. Vascular circulation abnormalities in iNPH may be reflected by changes in subfoveal and peripapillary choroidal thickness (PPChT)...

We present an unusual case of shunt nephritis in a 39-year-old male who presented 21 years after placement of a ventriculoperitoneal (VP) shunt. He complained of fevers, headaches, dizziness, and urticarial plaques on arms, trunks, and legs and was found to have anemia, low complement levels, elevated serum creatinine, proteinuria, and new onset microhematuria. Blood and urine cultures were negative. Renal biopsy showed features of acute tubulointerstitial nephritis attributed to vancomycin use. Glomeruli showed increased mesangial hypercellularity and segmental endocapillary proliferation...

INTRODUCTION: The published results of the Management of Myelomeningocele Study (MOMS) trial in 2011 showed improved outcomes (reduced need for shunting, decreased incidence of Chiari II malformation, and improved scores of mental development and motor function) in the fetal prenatal repair group compared to the postnatal group. Historically, endoscopic third ventriculostomy (ETV) remains as a controversial hydrocephalus treatment option with high failure rates in pediatric patients with a history of myelomeningocele (MMC)...

John K Houten, Shiela Smith, Amit Y Schwartz
BACKGROUND: Ventriculoperitoneal (VP) shunting is a common neurosurgical procedure to treat hydrocephalus that diverts cerebrospinal fluid from the cerebral ventricles to the peritoneal cavity for reabsorption. The distal catheter may potentially migrate though any potential or iatrogenic opening in the peritoneal cavity. Increasingly successfully management of childhood hydrocephalus and adult-onset conditions leading to hydrocephalus such as subarachnoid hemorrhage is leading many adult female patients harboring VP shunts needing to undergo hysterectomy...

BACKGROUND: The correlation between neurological outcome and frequency of overdrainage in the management of idiopathic normal pressure hydrocephalus (iNPH) using different ventriculoperitoneal shunt valve types is under investigation. Thus, we retrospectively compared one group of iNPH patients implanted with a programmable differential pressure valve (DPV) with another group treated by implantation of a DPV in combination with a flow-regulated anti-siphon device valve (ASD). METHODS: A retrospective evaluation of clinical outcome and frequency of overdrainage of 40 consecutive iNPH patients following surgical management between 08/2010 and 08/2014 was performed...

OBJECTIVES: Preoperative diagnosis of idiopathic normal-pressure hydrocephalus (iNPH) remains challenging. Recently, the presence of disproportionally enlarged subarachnoid spaces and hydrocephalus (DESH) on diagnostic images has been linked to clinical improvement after ventriculoperitoneal (VP) shunt placement. In this study we describe a new quantitative method to assess DESH on CT scans and to evaluate its prognostic value. PATIENTS AND METHODS: A multiplanar reconstruction software was used to retrospectively evaluate prospectively collected radiological data (CT scans) of 26 controls and 29 consecutive patients that underwent VP shunt placement for possible iNPH...

The role of school nurse today not only includes making a thorough assessment of the child but also the knowledge and skill to understand hidden medical devices. As of 2011, there were approximately 14.6 million children in the United States living with special health care needs. Many of these children could have hidden medical devices. The Specialized Health Needs Interagency Collaboration (SHNIC) program at the Kennedy Krieger Institute received requests for in-person training regarding ventriculoperitoneal (VP) shunts...
