“…Difficulties of the procedure are mainly the need for intubation of the patient and incorrect positioning of the frame that may require repositioning. 26 The procedure has been used to biopsy brainstem lesions via a suboccipital trepan with low complication rates. In 2014, a review of 20 publications including 457 patients who underwent stereotactic biopsy of lesions in the brainstem reported a rate of complications of 8.9%.…”

BACKGROUND Neurocysticercosis, caused by the larval stage of Taenia solium, affects the cerebral ventricles in 20–30% of cases and may lead to hydrocephalus and other neurological morbidity. Conventional treatment for cysts in the 4th ventricle includes open surgery (suboccipital approach) and neuroendoscopy, with the latter being the option of choice. Stereotactic surgery, minimally invasive, offers a good alternative for this type of deep lesion. OBSERVATIONS The authors report the cases of two women, 30 and 45 years old, who presented with headache, dizziness, and ataxia and were diagnosed with 4th ventricle cysticercosis. Magnetic resonance imaging (MRI) revealed dilated 4th ventricles (approximately 2.5 cm in both cases, with cystic images inside the ventricular cavity). Both patients were treated with stereotactic surgery via a suboccipital transcerebellar approach. Cyst material was extracted, and the diagnosis was confirmed by pathological examination. The surgeries had no complications and resulted in clinical improvement. Control MRI scans showed reduction of the volume of the ventricle without residual cysts. LESSONS Minimally invasive stereotactic surgery provided a safe alternative for 4th ventricle neurocysticercosis cysts, with more benefits than risks in comparison with conventional techniques.

“…Several stereotactic solutions have been developed to plan and perform surgery guided by MRI images with reported localization accuracy of less than 1 mm [26]. However, these systems are expensive and the shifts in brain position occurring during the craniotomy may result in the unnecessary removal of viable tissue, with recorded shifts at the cortical surface of up to 24 mm [27].…”

Background: Neurosurgeons regularly plan their surgery using magnetic resonance imaging (MRI) images, which may show a clear distinction between the area to be resected and the surrounding healthy brain tissue depending on the nature of the pathology. However, this distinction is often unclear with the naked eye during the surgical intervention, and it may be difficult to infer depth and an accurate volumetric interpretation from a series of MRI image slices. Objectives: In this work, MRI data are used to create affordable patient-specific 3-dimensional (3D) scale models of the brain which clearly indicate the location and extent of a tumour relative to brain surface features and important adjacent structures. Methods: This is achieved using custom software and rapid prototyping. In addition, functionally eloquent areas identified using functional MRI are integrated into the 3D models. Results: Preliminary in vivo results are presented for 2 patients. The accuracy of the technique was estimated both theoretically and by printing a geometrical phantom, with mean dimensional errors of less than 0.5 mm observed. Conclusions: This may provide a practical and cost-effective tool which can be used for training, and during neurosurgical planning and intervention.

“…The reason for using a logarithmic function is that the information content will be additive in the case that several FRs exist that have to be satisfied simultaneously (Kulak et al, 2010). Subsequently, when n FRs exist, the total information content will be the sum of all individual I ij (Fengqiang et al, 2008;Kulak et al, 2015).…”

The selection of waste lubricant oil regenerative technology regarding the complexity of the technologies and financial issues is a complex problem. Some risk factors exist regarding the ratings of technologies on the effective criteria. The current study tackles the selection of the technology based on fuzzy axiomatic design approach considering risk factors. Shannon entropy significance coefficients are computed for criteria. The problem is first solved by considering all criteria and then supplementary solutions are presented by categorizing the criteria to technical and economic groups. Two types of risk factors are identified for the technologies, i.e. general and specific risk factors.
