Perioperative Management for Rectal Migration of a Ventriculoperitoneal Shunt.

Ochsner J 2020 ;20(2):239-241

Department of Anesthesiology, Ochsner Clinic Foundation, New Orleans, LA.

While ventriculoperitoneal shunt (VPS) is the most commonly performed surgical procedure for treating hydrocephalus, complications following shunt placement are associated with a high mortality rate. Preoperative medical optimization and surgery are the primary means of correcting shunt migration. We present the case of an 11-week-old patient who underwent emergent surgical intervention for transrectal VPS migration and associated infection. Read More

Obstruction of Ventriculoperitoneal Shunt After Myelography-Report of a Unique Case and Its Treatment.

World Neurosurg 2020 Feb 20;134:443-447. Epub 2019 Nov 20.

Department of Neurological Surgery, Rutgers New Jersey Medical School, Newark, New Jersey, USA. Electronic address:

Background: Myelography, frequently supplanted by noninvasive, efficient magnetic resonance imaging, remains a useful technique when evaluating the spinal canal in nerve root avulsion, radiation therapy treatment planning, cerebrospinal fluid (CSF) loculation, and CSF leak. Myelography is achieved through a lumbar puncture and instillation of nonionic, water-soluble intrathecal iohexol (Omnipaque, GE Healthcare, Marlborough, Massachusetts, USA) contrast. The aim of the study was to highlight a possible complication of obstruction of a shunt valve due to an increased viscosity of the CSF after intrathecal Omnipaque contrast administration during myelography.

The role of lumboperitoneal shunts in managing chronic hydrocephalus with slit ventricles.

J Neurosurg Pediatr 2018 Dec;22(6):632-637

1Departments of Neurosurgery and Pediatric Neurosurgery, Wayne State University School of Medicine and Children's Hospital of Michigan, Detroit; and.

OBJECTIVELumboperitoneal (LP) shunts have a role not only in pseudotumor cerebri, but also in patients with slit-like ventricles who are treated with CSF shunting on a chronic basis. Hesitation to utilize LP shunts is based on previous conventional beliefs including the tendency for overdrainage, difficulties accessing the shunt to tap or revise, and risk of progressive cerebellar tonsillar herniation. The authors hypothesized that the use of horizontal-vertical (HV) valves may reduce the risk of these complications, particularly overdrainage and development of Chiari malformation. Read More

Ventriculoperitoneal shunt malfunction caused by proximal catheter fat obstruction.

J Clin Neurosci 2016 Aug 20;30:120-123. Epub 2016 Apr 20.

Department of Neurosurgery, Hadassah-Hebrew University Medical Center, P.O. Box 12000, Jerusalem 91120, Israel.

Ventriculoperitoneal (VP) shunt placement is the mainstay of treatment for hydrocephalus, yet shunts remain vulnerable to a variety of complications. Although fat droplet migration into the subarachnoid space and cerebrospinal fluid pathways following craniotomy has been observed, a VP shunt obstruction with fat droplets has never been reported to our knowledge. We present the first reported case of VP shunt catheter obstruction by migratory fat droplets in a 55-year-old woman who underwent suboccipital craniotomy for removal of a metastatic tumor of the left medullocerebellar region, without fat harvesting.

Background: Currently, the most common treatment for idiopathic normal pressure hydrocephalus (INPH) is a ventriculoperitoneal shunt (VPS), generally with programmable valve implantation. Endoscopic third ventriculostomy (ETV) is another treatment option, and it does not require prosthesis implantation.

Objective: To compare the functional neurological outcome in patients after 12 months of treatment with INPH by using 2 different techniques: ETV or VPS. Read More

Normal pressure hydrocephalus in the spectrum of neurological complications of systemic lupus erythematosus.

Neurol Sci 2013 Jun 25;34(6):1009-13. Epub 2012 Jul 25.

Normal pressure hydrocephalus is an unusual manifestation of systemic lupus erythematosus and its pathogenesis is still unclear. We report the case of a 39-year-old white woman with systemic lupus erythematosus who developed magnetic gait, speech difficulties, progressive memory impairment, urinary incontinence and episodes of involuntary closure of the eyelids. Signs and symptoms, associated with ventriculomegaly and normal cerebrospinal fluid pressure, suggested normal pressure hydrocephalus, which as a complication of systemic lupus erythematosus believably develops due to the insidious inflammatory process that occurs in the meningeal tissues or to the vasculitis itself.

On the method of a randomised comparison of programmable valves with and without gravitational units: the SVASONA study.

Acta Neurochir Suppl 2012 ;114:243-6

Department of Neurosurgery, Unfallkrankenhaus, Berlin, Germany.

Objective: The supremacy of low-pressure valves (LPV) in the therapy of patients with idiopathic normal pressure hydrocephalus (iNPH) has been proven by the Dutch NPH study. The downside of LPVs is the high rate of overdrainage complications. In the meantime gravitational units have been developed with the objective of minimising overdrainage complications. Read More

The value of the cerebrospinal fluid tap test for predicting shunt effectiveness in idiopathic normal pressure hydrocephalus.

Fluids Barriers CNS 2012 Jan 13;9(1). Epub 2012 Jan 13.

Normal Pressure Hydrocephalus Center, Otowa Hospital, Kyoto, Japan.

Background: The cerebrospinal fluid (CSF) tap test (TT) has been regarded as an important test for the prediction of shunt effectiveness in patients with suspected idiopathic normal pressure hydrocephalus (iNPH). Although its specificity and sensitivity are reportedly high, there remains some disagreement over this point. Herein, the TT as a test for predicting shunt effectiveness was investigated in our multicenter prospective study named SINPHONI and strategies to increase its predictability were examined.

Leucine-rich α-2-glycoprotein is a marker for idiopathic normal pressure hydrocephalus.

Acta Neurochir (Wien) 2011 Jun 19;153(6):1339-46; discussion 1346. Epub 2011 Feb 19.

Department of Neurosurgery, Juntendo University School of Medicine, 2-1-1 Hongo, Bunkyo-Ku, Tokyo, 113-8421, Japan.

Objective: Cerebrospinal fluid (CSF) shunting can improve symptoms of elderly patients' idiopathic normal pressure hydrocephalus (iNPH). However, adjunctive means for confirming the diagnosis remain unavailable. We have previously reported the specific increase of leucine-rich alpha-2-glycoprotein (LRG) in iNPH CSF, and the present study investigates its potential clinical applications. Read More

Is it possible to minimize overdrainage complications with gravitational units in patients with idiopathic normal pressure hydrocephalus? Protocol of the randomized controlled SVASONA Trial (ISRCTN51046698).

Acta Neurochir Suppl 2010 ;106:113-5

Department of Neurosurgery, Unfallkrankenhaus Berlin, Berlin, Germany.

Overdrainage is a common complication observed after shunting patients with idiopathic normal-pressure hydrocephalus (iNPH), with an estimated incidence up to 25%. Gravitational units that counterbalance intracranial pressure changes were developed to overcome this problem. We will set out to investigate whether the combination of a programmable valve and a gravitational unit (proGAV, Aesculap/Miethke, Germany) is capable of reducing the incidence of overdrainage and improving patient-centered outcomes compared to a conventional programmable valve (Medos-Codman, Johnson & Johnson, Germany).

Ventricular enlargement due to acute hypernatremia in a patient with a ventriculoperitoneal shunt.

J Neurosurg 2010 Jul;113(1):82-4

Department of Neurosurgery, Stanford University Medical Center, Stanford, California 94305, USA.

Patients requiring CSF shunts frequently have comorbidities that can influence water and electrolyte balances. The authors report on a case involving a ventriculoperitoneal shunt in a patient who underwent intravenous hyperhydration and withdrawal of vasopressin substitution prior to scheduled high-dose chemotherapy regimen for a metastatic suprasellar germinoma. After acute neurological deterioration, the patient underwent CT scanning that demonstrated ventriculomegaly. Read More

[Lumboperitoneal shunt in an outpatient setting for the treatment of chronic hydrocephalus in adults. A study and follow-up of 30 cases].

Rev Neurol 2009 Sep 16-30;49(6):300-6

Servicio de Neurocirugía, Hospital General Universitario de Valencia, 46014 Valencia, Espana.

Introduction And Aims: One of the therapeutic options for chronic adult hydrocephalus that has become widely used in our service is the lumboperitoneal shunt with low-pressure Spetzler catheter and in an outpatient regimen. We report on the first 30 patients treated in this way with a follow-up of between one and five years.

Patients And Methods: Diagnosis was reached after studying the patient history and a clinical examination; Hakim and Adams' triad was found to be a primary and highly predictive factor, together with flow magnetic resonance imaging and the use of the ambulatory tap test. Read More

Rethinking the indications for the ventriculoperitoneal shunt tap.

J Neurosurg Pediatr 2008 Jun;1(6):435-8

Department of Neurological Surgery, University Hospitals of Cleveland, Cleveland, Ohio 44106, USA.

Object: Tapping of a suspected malfunctioning ventriculoperitoneal shunt is usually easy, sometimes informative, but also potentially misleading. The purpose of this study was to determine the effectiveness of a shunt evaluation protocol that does not involve direct shunt tapping except in rare and specific cases.

Methods: The authors adopted a protocol for shunt evaluation that involves shunt tapping only in selected cases of suspected infection or in patients with noncommunicating hydrocephalus and equivocal computed tomography (CT) findings of shunt infection. Read More

Predicting the outcome of shunt surgery in normal pressure hydrocephalus.

J Clin Neurosci 2007 Aug 12;14(8):729-36. Epub 2007 Jan 12.

Department of Neurosurgery, Haydarpasa Numune Education and Research Hospital, Uskudar, Istanbul, Turkey.

We studied retrospectively the effectiveness of the repeated lumbar CSF tap test (RTT), lumbar external CSF drainage (LED) and radioisotope cisternography (RIC) in predicting the outcome of shunt surgery, as well as the diagnostic and prognostic value of periventricular hyperintensity (PVH) and of the classic clinical triad in normal pressure hydrocephalus. Two hundred and seventy patients were referred to the Departments of Neurosurgery, in Nancy, France and in Istanbul, Turkey. The decision to perform surgery was based on the clinical presentation (all patients had at least two symptoms of the classic clinical triad), neuroimaging examinations and the results of the RTT (taps were performed on three consecutive days and at each tap a minimum of 30 to 40 cc of CSF was removed), the LED (drainage was performed for 3 days and the volume of CSF drained daily was a minimum of 150 to 250 cc) or the RIC.
