Professional Practice and Neurosurgery: What Every Neurosurgeon Should Know about Malpractice

Introduction The objective of the present study was to review the epidemiological aspects of malpractice in neurosurgery and to identify preventive measures regarding malpractice for neurosurgeons. Methods The following terms (alone or in combination) were searched in the PubMed and Biblioteca Virtual em Saúde databases: neurosurgery (neurocirurgia), lawsuits (ações judiciais), malpractice (erro médico), and litigation (litígio) and identifying studies on these topics published from 2000 to April 2018. Literature Review In Brazil, 6.9% of the physicians are sued per year. The most common type of malpractice alleged in litigation is negligence. According to the literature, the neurosurgical disease that has sparked the most litigation is spinal disease. The outcomes of these cases vary: sometimes the neurosurgeon prevails, and at other times the plaintiff prevails. To prevent or reduce malpractice claims, the neurosurgeon should take the following precautions: 1. follow medical protocols; 2. perform surgeries in an environment consistent with good medical practice; 3. evaluate and monitor antibiotic prophylaxis; 4. develop a good relationship with the patient based on ethics, good faith and transparency; 5. request the presence of the patient and of his or her family when there is a problem in order to didactically explain the case; 6. keep good medical records to document all of the actions performed (informed consent and description of the surgery and of the pre and postoperative); 7. always seek technical improvement (continuing education/professional development); 8. in the case of attending physicians, monitor patients, treating any postoperative complications; and 9. conduct multidisciplinary team meetings to optimize treatment decisions and to share responsibility for making difficult decisions.

Estudo da anatomia endoscópica ventricular em cadáveres humanos brasileiros não fixados para realização de terceiro ventriculostomia / Study of ventricular endoscopic anatomy on Brazilian human cadavers non-fixed for the performance of the third ventriculostomy

INTRODUÇÃO: O objetivo desta pesquisa foi medir, através da endoscopia, o plexo corióideo no forame interventricular e estruturas no assoalho do terceiro ventrículo, bem como a distância entre as artérias comunicantes posteriores e comparar essas variáveis. MÉTODOS: Estudo observacional, prospectivo realizado em 37 cérebros de cadáveres humanos adultos, de ambos os sexos, no Serviço de Verificação de Óbitos da Universidade de São Paulo, em abril de 2008, utilizando neuroendoscópio rígido. As imagens endoscópicas foram gravadas, corrigidas para distorção e mensuradas. A medida macroscópica entre as artérias comunicantes posteriores foi realizada após o estudo endoscópico. RESULTADOS: As medidas do plexo corióideo no forame interventricular, a distância látero-lateral dos corpos mamilares, a distância do recesso do infundíbulo até os corpos mamilares e do triângulo de segurança no túber cinéreo foram 1,71 mm (±0,77 mm), 2,23 mm (±0,74 mm), 3,22 mm (±0,82 mm), 3,69 mm2 (±2,09 mm2), respectivamente. O aspecto do assoalho do terceiro ventrículo e a distância interna dos corpos mamilares foi 84% opaco e 89% ausente, respectivamente. A distância média entre as artérias comunicantes posteriores foi de 12,5 mm (±2,3 mm). Associações entre translucidez do assoalho do terceiro ventrículo com as seguintes variáveis: distância láterolateral e distância interna dos corpos mamilares, assim como idade, foram identificadas. CONCLUSÕES: Até esta pesquisa, não existiam medidas sobre o plexo corióideo no forame interventricular e distância entre as artérias comunicantes posteriores na região dos corpos mamilares. As variáveis restantes, quando comparadas com a literatura, foram em maior número e em cérebros normais.

INTRODUCTION: the objective of this research was to measure, through endoscopy, the interventricular foramen choroid plexus and the third ventricle floor structures, as well the distance between the communicating posterior arteries and compare these variables. METHODS: an observational, prospective study was conducted in 37 brains of adult human cadavers, of both sexes at the Death Check Unit of the University of São Paulo, in April 2008 by means of the rigid neuroendoscope. The endoscopic images were recorded, corrected for distortion and measured. The macroscopic measure between the communicating posterior arteries was performed after the endoscopic study. RESULTS: The measures of the interventricular foramen choroid plexus, the latero-lateral distance of mammillary bodies, the distance from the infundibular recess to the mammillary bodies, safety triangle in the tuber cinereum were 1.71 mm (±0.77 mm), 2.23 mm (±0.74 mm), 3.22 mm (±0.82 mm), 3.69 mm2 (±2.09 mm2), respectively. The aspect of the third ventricle floor and the internal distance of the mammillary bodies was 84% opaque and 89% absent, respectively. The mean distance between the communicating posterior arteries was 12.5 mm (±2.3 mm). Associations between the translucent floor of the third ventricle with the following variables: latero-lateral distance and internal distance of the mammillary bodies, as well as age were identified. CONCLUSIONS: Up this research, there was no account on the measures of the interventricular foramen choroid plexus and the distance between communicating posterior arteries at the level of the mammillary bodies. The remaining variables were in greater number and in normal brains, as compared with the literature.
