Background.: Little is known regarding the optimal treatment of ventriculoperitoneal (VP) shunt infections in adults. Our aim was to assess the efficacy of treatment strategies and to identify factors that predict failure. Methods.: Retrospective, observational study of patients aged ≥12 years with VP shunt infections (1980 -2014). Therapeutic approaches were classified under 4 headings: only antibiotics (OA), one-stage shunt replacement (OSSR), two-stage shunt replacement (TSSR), and shunt removal without replacement (SR)...

The management of ventriculoperitoneal (VP) shunt failure is a common problem in neurosurgical practice. On occasion, extraperitoneal sites for CSF diversion are required when shunting to the peritoneal cavity has failed after multiple attempts. The authors report a novel minimally invasive procedure allowing cannulation of the ureter for the purpose of ventriculo-ureteral (VU) shunting. Sixteen years prior to presentation, this 46-year-old woman had contracted tuberculous meningitis and had chronic hydrocephalus, with multiple distal shunt failures in recent months...

OBJECTIVES: There have been no nationwide epidemiological studies of idiopathic normal pressure hydrocephalus (iNPH) in Japan. Therefore, a nationwide epidemiologic survey of iNPH was performed to determine the number of cases and clinical characteristics by sex and diagnostic level. METHODS: The first survey examined the numbers of cases that met the diagnostic criteria of iNPH and those who underwent shunt operations in 2012. The second survey gathered patients' details to clarify their clinical background characteristics...

Migration of the distal catheters of ventriculoperitoneal (VP) shunt is a rare event. Here, we report an unusual case of a 5-month-old infant with post-hemorrhagic hydrocephalus, who developed right scrotum swelling soon after VP shunting. Plain abdominal x-ray showed the shunt tubing, which was twisted and kinked in its distal portion and coiled in the right scrotum. The infant was operated on and managed with successful outcome.

BACKGROUND: We showed that ventriculoperitoneal (VP) shunt and lumboperitoneal (LP) shunt surgeries are beneficial for patients with idiopathic normal pressure hydrocephalus (iNPH) in the Study of Idiopathic Normal Pressure Hydrocephalus on Neurological Improvement (SINPHONI; a multicenter prospective cohort study) and in SINPHONI-2 (a multicenter randomized trial). Although therapeutic efficacy is important, cost-effectiveness analysis is equally valuable. METHODS: Using both a set of assumptions and using the data from SINPHONI and SINPHONI-2, we estimated the total cost of treatment for iNPH, which consists of medical expenses (e...

INTRODUCTION: Management of pregnancy and delivery of a patient with a history of myelomeningocele requires a multidisciplinary team approach. CASE REPORT: We report a case of pregnancy and delivery by a patient who had a history of myelomeningocele surgical repair, ventriculoperitoneal (VP) shunt, and bladder augmentation enterocystoplasty. Regarding types of delivery style, anesthesiologists recommended a Cesarean section under general anesthesia. However, urologists recommended a vaginal delivery because they were concerned that she would require a nephrostomy because of severe adhesion between her uterus and the neobladder if she had a Cesarean section...

The ventricle peritoneal (VP) shunt is commonly used in the treatment of hydrocephalus. It is a relatively simple and effective technique, but around 70% of the patients with a VP shunt have a complication in their lifetime. Most of these complications are due to infection or mechanical dysfunction. The thoracic complications are rare. The present case is one of the small number of them found in the literature, describing hydrothorax as a complication of a VP shunt without catheter migration and without ascites...

Nutritional variant streptococci (NVS) are difficult to identify bacteria that can cause invasive infections such as endocarditis and meningitis. NVS as a cause of peritonitis has not been routinely described. This case of NVS as the etiology of peritonitis associated with previous neurosurgery and ventriculoperitoneal (VP) shunt revision demonstrates its potential role as a significant pathogen in patients with peritonitis and VP shunts. Therapy consists of vancomycin plus a second agent but since there are no standards for susceptibility testing, clinical response remains the standard for determining the efficacy of treatment...

A male neonate was referred to our hospital for the treatment of myelomeningocele and hydrocephalus related to Chiari malformation type 2. After the placement of ventriculoperitoneal (VP) shunt for hydrocephalus, an intracranial cyst, which was asymptomatic at first, expanded and caused clinical symptoms due to increased intracranial pressure. The expansion of the cyst was confirmed dominantly in the right lateral ventricle where the VP shunt was inserted. Intraoperative findings through a neuroendoscope suggested that the expanded cyst was an isolated lesion...

OBJECTIVE Patients with ventriculoperitoneal (VP) shunts with programmable valves who would benefit from osseointegrated hearing devices (OIHDs) represent a unique population. The aim of this study was to evaluate the magnetic field strengths of 4 OIHDs and their interactions with 5 programmable VP shunt valves. METHODS Magnetic field strength was measured as a function of distance for each hearing device (Cochlear Baha 5, Cochlear Baha BP110, Oticon Ponto Plus Power, and Medtronic Sophono) in the following modes: inactive, active in quiet, and active in 60 decibels of background noise in the sound booth...

The authors report on a patient harbouring an unruptured cortical arteriovenous malformation (AVM), who had presented with obstructive hydrocephalus due to compression of the cerebral aqueduct by a large venous varix. A ventriculoperitoneal (VP) shunt was inserted in emergency. Due to its large volume, the AVM was not referred for treatment and a follow-up policy was chosen. After the second VP shunt dysfunction, endoscopic third ventriculostomy was performed under neuronavigation. The procedure went uneventfully and the patient recovered well...

PURPOSE: We have discussed the diagnosis and treatment approaches in patients with discontinued (disconnected or fractured) ventriculoperitoneal (VP) shunts that caused mechanical dysfunction. METHODS: Between 2006 and 2016, VP shunt surgery was performed on 1357 pediatric patients in our clinic. In follow-up examinations, we retrospectively reviewed patients who underwent revision surgery. Except for diagnosis of discontinued VP shunt, by excluding revision-surgery patients, only those patients who underwent surgical treatment owing to discontinued (fracture or disconnection) catheter were included in the study...

Ventriculoperitoneal (VP) shunting remains invaluable in the management of hydrocephalus. It is a common procedure that can be complicated by shunt malfunction due to infection, blockage and disconnection. Spontaneous peritoneal catheter knot formation causing CSF flow obstruction is a rare phenomenon. We present a case of a 12years old boy with spontaneous knot formation in the peritoneal catheter causing VP shunt obstruction and hydrocephalus.

OBJECTIVES: Normal pressure hydrocephalus (NPH) is a treatable neurological disorder that appears in older adults, lacks specific diagnostic criteria, and resembles symptoms seen in Alzheimer's disease (AD). Presently, differentiating NPH from AD in the early stages of symptom presentation remains difficult. This study established whether olfactory testing may be useful in this regard. In addition, we determined whether olfactory function of NPH patients differed before and after extended lumbar drainage (ELD), as well as six months after surgical implantation of a ventriculoperitoneal (VP) shunt...
