ABSTRACT

Idiopathic normal pressure hydrocephalus (iNPH) is characterized by gait disturbance, dementia and /or urinary incontinence, dilation of the ventricular system and normal opening cerebrospinal fluid pressure. Shunt surgery is the standard treatment of iNHP. Diversions with programmable valves are recommended, once drainage pressure can be changed. However, well-defined protocols still lack guiding the steps to attain proper pressure for each patient. Methods: In our study, we reported the experience of shunting 24 patients with iNPH using Strata® (Medtronic) valve, following a protocol based on a positive Tap Test. Results: We observed clinical improvement in 20 patients and stability/worsening in 4 patients. Complications occurred in five patients, including one death. The results display improvement, and complications occurred at a lower rate than reported in other studies. Conclusions: The Strata® valve used in the proposed protocol represents an efficient and safe tool in the treatment of iNPH. .


A hidrocefalia de pressão normal idiopática (iNPH) é caracterizada por alterações na marcha, demência e/ou incontinência urinária, além de dilatação dos ventrículos com pressão normal de abertura no líquido cefalorraquidiano. A cirurgia de derivação é o principal tratamento da iNHP. São recomendadas válvulas programáveis, pois a pressão de drenagem pode ser alterada. Embora as válvulas programáveis sejam utilizadas, não há protocolos para atingir a pressão adequada de cada paciente. Métodos: Neste estudo, relatamos nossa experiência com 24 pacientes com iNPH que usaram a válvula Strata® (Medtronic), seguindo protocolo baseado em um Tap test positivo. Resultados: Observamos melhora em 20 pacientes e estabilidade ou piora em 4. Ocorreram complicações em cinco pacientes, tendo um deles falecido. Houve importante melhora clínica, e as complicações ocorreram em taxa mais baixa do que as relatadas em outros estudos. Conclusões: A válvula Strata® utilizada no protocolo proposto representa uma ferramenta eficiente e segura no tratamento de iNPH. .

ABSTRACT

Patients with hydrocephalus and risk factors for overdrainage may be submitted to ventricular shunt (VS) implant with antisiphon device. The objective of this study was to prospectively evaluate for two years the clinical and tomographic results of the implant of fixed-pressure valves with antisiphon device SPHERA® in 35 adult patients, with hydrocephalus and risk factors for overdrainage. Of these, 3 had congenital hydrocephalus in adult patients with very dilated ventricles (Evans index >50%), 3 had symptomatic overdrainage after previous VS implant (subdural hematoma, hygroma or slit ventricle syndrome), 1 had previous chronic subdural hematoma, 15 had normal pressure hydrocephalus with final lumbar pressure <5 cm H2O after tap test (40 mL), 6 had pseudotumor cerebri, and 7 had hydrocephalus due to other causes. Clinical improvement was observed and sustained in 94.3% of the patients during the two-year period with no computed tomography (CT) evidence of hypo or overdrainage, and no immediate early or late significant complications.


Pacientes com hidrocefalia e fatores de risco para hiperdrenagem podem ser submetidos ao implante de derivação ventricular (VS) com mecanismo antissifão. O objetivo deste trabalho foi avaliar prospectivamente os resultados clínicos e tomográficos do implante de válvulas de pressão fixa com antissifão SPHERA® em 35 pacientes adultos, com hidrocefalia e risco de hiperdrenagem, acompanhados por dois anos. Destes, 3 apresentavam hidrocefalia congênita em adulto, com ventrículos muito dilatados (índice de Evans >50%); 3 tinham hiperdrenagem sintomática pós-derivação ventricular prévia (hematoma subdural, higroma ou síndrome dos ventrículos colabados; 1 apresentava hematoma subdural crônico pregresso; 15 apresentavam hidrocefalia de pressão normal com pressão lombar final <5 cm H2O após tap test (40 mL); 6 apresentavam pseudotumor cerebral; e 7, devido a outras causas. A melhoria clínica foi detectada e sustentada em 94,3% dos pacientes no período de dois anos, sem indícios tomográficos de hipo ou hiperdrenagem e sem complicações significativas imediatas, precoces ou tardias.

ABSTRACT

Ventriculo-subgaleal (VSG) shunt placement is an option for temporary CSF diversion in neonate suffering from hydrocephalus. The authors describe step-by-step technique of VSG shunt assembly and insertion by using previously-cut shunt tubes and connector. It is simple and inexpensive. The authors also present a short review of the literature of the VSG shunt.

ABSTRACT

O presente relato refere-se ao caso de uma criança portadora de derivaçäo liquórica, para tratamento de hidrocefalia, que apresentou quadro de HIC durante madrugadas sucessivas mas que, ao comparecer ao médico pela manhä, sempre se encontrava assintomática. Os exames complementares realizados (TC do crânio, Rx do crânio, Rx do abdome e LCR) foram considerados normais. Para esclarecimento diagnóstico, a criança foi internada. Durante a internaçäo, entrou em coma com atitude de decorticaçäo. Através de punçäo direta da derivaçäo, foi detectada hipertensäo liquórica e procedido sua revisäo cirúrgica. Atualmente a criança encontra-se bem, com bom rendimento escolar

ABSTRACT

Shunting of cerebrospinal fluid into the peritoneal cavity is a well established procedure which has, over the years, enjoyed increasing popularity. A slit valve at the distal end elminated the insinuation of the omentum into the shunting tube and a spring catheter prevented kinking of the shunt tubing. However, the most common cause of failure of the shunting is from the separation, or pulling apart, of the various components of the shunt system with subsequent infection. A one piece spring catheter is sufficient to the necessity. Surgical details are illustrated for installing a one piece spring catheter for hydrocephalus. Four basic steps of surgical procedure using a subcutaneous guide, a leader, a cannula and a cuff are described; firstly passing the guide and the one piece shunt from McBurney's point to the supraclavicular space, secondly passing the guide from the parietal eminence to the supraclavicular space to thread the one piece shunt cephalad. Thirdly, inserting the cannula into the lateral ventricle and threading the ventricular end of the one piece shunt through the cuff into the lateral ventricle and fourthly inserting the peritoneal end into the peritoneal cavity.
