- Surgical technique of retrograde ventricle-sinus shunt is an option for the treatment of hydrocephalus in infants after surgical repair of myelomeningocele(2015) OLIVEIRA, Matheus Fernandes de; TEIXEIRA, Manoel Jacobsen; NORREMOSE, Karen Andrade; MATUSHITA, Hamilton; OLIVEIRA, Marcelo de Lima; SHU, Edson Bor Seng; PINTO, Fernando Campos GomesIntroduction: Treatment of hydrocephalus is accomplished primarily through a ventricular-peritoneal shunt (VPS). This study aims to describe the application of retrograde ventricle-sinus shunt (RVSS) in patients with hydrocephalus after surgical treatment of myelomeningocele. Method: A prospective, randomized and controlled pilot study. We consecutively enrolled 9 patients with hydrocephalus after surgical repair of myelomeningocele from January 2010 to January 2012. These patients underwent elective RVSS or VPS. Five underwent RVSS and 4 underwent VPS. Patients were followed for one year with quarterly evaluations and application of transcranial Doppler. Results: RVSS group showed outcomes similar to those of VPS group. Doppler revealed significant improvement when comparing preoperative to postoperative period. RVSS group had significantly higher cephalic perimeter than VPS group. Neuropsychomotor development, complications and subjective outcomes did not differ between groups. Conclusion: RVSS shunt is viable; it is an alternative option for the treatment of hydrocephalus.
- Development of the Brazilian Portuguese version of the ""Grading scale for idiopathic normal pressure hydrocephalus"": cross-cultural adaptation, reliability and validity(2018) LOPES, Maria Izabel Romao; TORNAI, Juliana Benevenuto; JENG, Fernanda Letkaske de Miranda; LOPES, Bianca di Virgilio; MENDES, Gabriel Andre da Silva; OLIVEIRA, Matheus Fernandes de; PINTO, Fernando Campos GomesObjective: The current study translated to Portuguese and validated the normal pressure hydrocephalus (NPH) scale originally developed in English as the Grading Scale for Idiopathic Normal Pressure Hydrocephalus. Methods: Following Guillemin's validation protocol, the last version of the Portuguese NPH scale was applied to 121 consecutive patients with a diagnosis of normal pressure hydrocephalus (73 men and 48 women) from the Group of Cerebral Hydrodynamics from July 2010 to March 2012. Results: The mean age was 71.09 years old, ranging from 35 to 92 years. The rate of agreement and reproducibility was high, as confirmed by Cohen's Kappa coefficient, with excellent intraobserver correlation for the NPH scale items individually evaluated: gait (0.80), dementia (0.90) and incontinence (0.87). Conclusions: The Portuguese version of the Grading Scale for Idiopathic Normal Pressure Hydrocephalus was successfully translated and validated for use in Brazilian patients.
- Evaluation of Head Computed Tomography Assessment of Brain Swelling after Acute Traumatic Brain Injury: A Pilot study(2019) AMORIM, Robson Luis; MORAIS, Barbara Albuquerque; PEREIRA, Francisco Otavio Camargo; OLIVEIRA, Matheus Fernandes; ANDRADE, Almir Ferreira; BOR-SENG-SHU, Edson; OLIVEIRA, Marcelo Lima; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson SilvaObjective To evaluate the interobserver reliability of a new scale created for quantitatively assessing brain swelling in traumatic brain injury (TBI) patients using the computed tomography (CT) findings in three levels. Methods Computed tomography scans of severe head injury patients were randomly selected from a tertiary hospital image database and evaluated by independent groups of neurosurgeons, neurosurgery residents, radiologists, and intensivists from the same hospital. Each specialist assessed the tomographic findings, applying zero to six points in a new scale. The Kappa coefficient was calculated to assess interobserver agreement. Results The highest reliability coefficient was obtained by the neurosurgeons group (0.791; 95% confidence interval [CI]: 0.975-0.607; p < 0.001), followed by the neurosurgery residents group (0.402; 95%CI: 0.569-0.236; p < 0.001) and by the radiologists group (0.301; 95%CI: 0.488-0.113; p < 0.002). The lowest coefficient was found among the intensivists (0.248; 95%CI: 0.415-0.081; p = 0.004). Conclusion The proposed scale showed good reliability among neurosurgeons, and moderate overall reliability. This tomographic classification might be useful to better assist severe TBI victims, allowing to identify the worsening or amelioration of brain swelling, which should be further investigated. The scale seems to be feasible, even in low income countries, where the cost of intracranial pressure (ICP) monitoring is higher than that of CTs.
- Clinical performance of fixed-pressure Sphera Duo (R) hydrocephalus shunt(2020) PINTO, Fernando Campos Gomes; OLIVEIRA, Matheus Fernandes de; CASTRO, Joao Paulo Souza de; MORAIS, Joao Vitor Rocha; PINTO, Flavia Morais Gomes; TEIXEIRA, Manoel JacobsenIntroduction: Cerebral hydrodynamics complications in shunted patients are due to the malfunction of the system. The objective of this retrospective, single-center, single-arm cohort study is to confirm the safety and performance of Sphera (R) Duo when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cysts. Methods: Data were generated by reviewing 112 adult patient's charts, who were submitted to a ventriculoperitoneal shunt surgery and followed for one year after surgery. Results: The results show us that 76% of patients had their neurological symptoms improved and that the reoperation rate was 15% in the first year following surgery. Discussion: Sphera Duo (R) shunt system is an applicable shunt option in routine neurosurgical management of hydrocephalus by several causes. It has presented good results while mitigating effects of overdrainage. Overdrainage is especially important in adults with non-hypertensive hydrocephalus and can cause functional shunt failure, which causes subnormal ICP (particularly in the upright position) and is associated with characteristic neurological symptoms, such as postural headache and nausea. Conclusion: Sphera Duo (R) shunt system is safe when used in adult patients suffering from hydrocephalus, pseudotumor cerebri or arachnoid cyst.
- Revisiting Retrograde Ventriculosinus Shunt as an Alternative for Treating Hydrocephalus in Children(2017) OLIVEIRA, Matheus Fernandes; TEIXEIRA, Manoel Jacobsen; OLIVEIRA, Marcelo Lima; SHU, Edson Bor Seng; PINTO, Fernando Campos GomesIntroduction Retrograde ventriculosinus shunt (RVSS) is a useful option in the daily routine of neurosurgeons dealing with hydrodynamics. The objective of this manuscript is to review the main data about RVSS. Methods We performed a critical review. The keywords used were hydrocephalus, shunt, venous sinus, ventriculosinus shunt, retrograde ventriculosinus shunt, and sagittal sinus. The search was performed in the Medline (Pubmed) and EMBASE databases. Results Van Canneyt et al (2008) and Pinto et al (2016) performed experimental studies confirming the effectiveness of RVSS. El Shafei et al (1985, 1987, 2001) authors reported several cases treated with efficacy and few complications. Oliveira et al (2015, 2016) compared RVSS and ventriculoperitoneal shunt (VPS) in the treatment of hydrocephalus after myelomeningocele repair in infants, with similar functional results. Oliveira et al (2015, 2016) also described the applicability of RVSS in situations when VPS is not feasible, or when the peritoneum is not useful. Discussion Retrograde ventriculosinus shunt is a safe and more physiological option, which requires the use of less prostheticmaterial. It is feasible and applicable. Especially in children, it generates a normotensive state after shunting, allowing centrifugal head growth, once there is no intracranial hypotension due to overdrainage, which may reflect in long-term better psychomotor development. Conclusions The surgical technique of RVSS is feasible. The clinical results are comparable with those of the VPS.
