RESUMO
OBJECTIVE: To study the impact of surgery on pain, disability, quality of life, and patient satisfaction in a sample of patients with Degenerative Lumbar Disease (DLD). METHODS: Retrospective analysis of prospectively collected data. Comparison between pre and postoperative (6 - 12 months) ODI and SF-36, plus postoperative Patient Satisfaction Index. RESULTS: From a total of 216 patients included, improvement was observed in average scores of pain (201.2%), disability (39.7%), physical quality of life (42%), and mental quality of life (37.8%). Among these patients, 57.7% reached or surpassed the minimal clinically important difference (MCID) for ODI, 57.7% for the SF-36 pain component, 59.7% for the SF-36 physical component summary, and 50.5% achieved or surpassed the MCID for the SF-36 mental component summary. CONCLUSIONS: Surgery produced a significantly positive impact on pain, disability, and quality of life of patients. Overall, 82.5% of the patients were satisfied.

OBJECTIVE: A new ventriculostomy technique through the lamina terminalis is described. This technique is applied mainly during aneurysm surgery at the acute stage. METHOD: Thirteen patients were operated on intracranial aneurysms and, during the procedure, had the lamina terminalis fenestrated. A ventricular catheter was inserted into the third ventricule, left in place and connected to an external drainage system for further intracranial pressure (ICP) monitoring and/or cerebrospinal fluid (CSF) drainage. RESULTS: ICP readings and CSF drainage were obtained in all cases. No complication was recorded. CONCLUSION: Third ventriculostomy through the lamina terminalis is a simple and easy technique that can be used as an alternative to conventional ventriculostomy. This procedure can be indicated in cases where the ventricule is not reached by means of another technique, and when the decision to perform ventriculostomy is made at the end of aneurysm surgery.

OBJECTIVE: Recent advances in neuroimaging techniques have resulted in more frequent detection of unruptured intracranial aneurysms. Regardless of the method employed, most interventions to treat lesions have low morbidity and mortality rates. Recently, some studies have suggested that changes in cognitive status are one complication of microsurgical treatments. However, no study to date has performed any behavioral analysis. Moreover, cognitive assessment beyond 12 months after surgical intervention is missing. The current study sought to evaluate the long-term impact of clipping on the behavioral and cognitive functions of patients with unruptured intracranial aneurysms. METHOD: A within-subjects prospective clinical trial was performed to evaluate 40 patients who underwent microsurgical clipping for incidental unruptured intracranial aneurysms. The participants underwent a full neuropsychological evaluation during the preoperative period, at 3 months after surgery and at 3 years after surgery. Paired Student's t tests and an ANOVA, followed by a Bonferroni post hoc test, were used to examine group differences. RESULTS: The cognitive and behavioral test performance of the patients did not deteriorate during either the short or the long term following intervention. Moreover, the patients' clinical and demographic characteristics did not predict behavioral or cognitive changes, and neither the surgical approach nor the topography, multiplicity, or size of the aneurysms affected the results. CONCLUSIONS: In either the short or the long term following clipping for patients with incidental unruptured intracranial aneurysms, behavioral and cognitive functions had no significant change from baseline. The intervention demonstrated high efficacy and was associated with a low morbidity rate.

BACKGROUND: As a consequence of the progressive evolution of neurosurgical techniques, there has been increasing concern with the esthetic aspects of burr holes. Therefore, the objective of this study was to compare the use of cortical bone graft and bone dust for correcting cranial deformities caused by neurosurgical trephines. METHODS: Twenty-three patients were enrolled for cranial burr hole reconstruction with a 1-year follow-up. A total of 108 burr holes were treated; 36 burr holes were reconstructed with autogenous cortical bone discs (33.3%), and the remaining 72 with autogenous wet bone powder (66.6%). A trephine was specifically designed to produce this coin-shaped bone plug of 14 mm in diameter, which fit perfectly over the burr holes. The reconstructions were studied 12 months after the surgical procedure, using three-dimensional quantitative computed tomography. Additionally, general and plastic surgeons blinded for the study evaluated the cosmetic results of those areas, attributing scores from 0 to 10. RESULTS: The mean bone densities were 987.95 ± 186.83 Hounsfield units (HU) for bone fragment and 473.55 ± 220.34 HU for bone dust (P < 0.001); the mean cosmetic scores were 9.5 for bone fragment and 5.7 for bone dust (P < 0.001). CONCLUSIONS: The use of autologous bone discs showed better results than bone dust for the reconstruction of cranial burr holes because of their lower degree of bone resorption and, consequently, better cosmetic results. The lack of donor site morbidity associated with procedural low cost qualifies the cortical autograft as the first choice for correcting cranial defects created by neurosurgical trephines.
RESUMO
OBJECTIVE: It is a consensus that most unruptured intracranial aneurysms (UIA) can be treated with acceptably low morbidity. However, some studies recently reported postoperative cognitive impairment, suggesting that it could be attributable to surgical damage. Our goal is to evaluate cognitive function before and after microsurgical clipping in patients with UIA. METHOD: A consecutive series of 40 patients who underwent microsurgical clipping for UIA were studied. The cognitive assessment (Mini Mental State Examination, MMSE) was performed immediately before and at least one month after surgery. Paired Student's "t" test and analysis of variance (ANOVA) were used for statistical purposes. RESULTS: The mean MMSE score in the preoperative analysis was 28.12 (SD, 1.34). In the postoperative period the mean MMSE score was 28.40 (SD, 1.46). Paired Student's "t" test was applied to the scores and no significant difference was found (p = 0.315). ANOVA did not find independent associations between MMSE scores and age, hypertension, smoking, dyslipidemia, education, aneurysm location, number, laterality or size. CONCLUSION: The present study suggests that microsurgical clipping for UIA does not result in major cognitive dysfunction as determined by the MMSE.

OBJETIVO: É consenso que a maioria dos aneurismas intracranianos não-rotos (AINR) podem ser tratados com aceitável taxa de morbidade. Entretanto, alguns estudos reportaram déficits cognitivos no pós-operatório, sugerindo que poderiam ser atribuídos ao dano cirúrgico. O objetivo desse estudo é avaliar a função cognitiva antes e após clipagem microcirúrgica em pacientes com AINR. MÉTODO: Uma série de 40 pacientes com AINR submetidos à clipagem microcirúrgica foi estudada. A avaliação cognitiva (Mini Exame do Estado Mental, MEEM) foi realizada antes e após a intervenção cirúrgica. A análise estatística foi realizada com teste "t" de Student e análise de variância (ANOVA). RESULTADOS: A média dos escores do MEEM na análise pré-operatória foi 28,12 (DP, 1,34). No período pós-operatório, a média dos escores foi 28,40 (DP, 1,46). Não houve diferença estatística (teste "t" de Student; p=0,315). A ANOVA não encontrou associações independentes entre os escores de MEEM e idade, hipertensão, tabagismo, dislipidemia, educação e características dos aneurismas (topografia, número, lado e tamanho). CONCLUSÃO: O presente estudo sugere que a clipagem microcirúrgica não está associada a danos cognitivos maiores em pacientes com AINR.
