    Endoscopic and Gravity-Assisted Resection of Medial Temporo-occipital Lesions Through a Supracerebellar Transtentorial Approach: Technical Notes With Case Illustrations
    (2015) Villanueva, Pablo; Louis, Robert G.; Cutler, Aaron R.; Wei, Hua; Sale, Danjuma; Duong, Huy T.; Barkhoudarian, Garni; Kelly, Daniel F.
    BACKGROUND: Traditional approaches to medial temporo-occipital Intra-axial brain tumors carry the risk of visual or language deficits related to brain retraction or transgression of deep fiber tracts. To reduce these risks, the microscopic supracerebellar transtentorial approach with the patient in the sitting position has been previously described for lesions in relative proximity to the tentorium.

    Reusable Low-Cost 3D Training Model for Aneurysm Clipping
    (2021) Mery, Francisco; Aranda, Francisco; Mendez-Orellana, Carolina; Caro, Ivan; Pesenti, Jose; Torres, Javier; Rojas, Ricardo; Villanueva, Pablo; Germano, Isabelle
    BACKGROUND: Aneurysm clipping requires the proficiency of several skills, yet the traditional way of practicing them has been recently challenged, especially by the growth of endovascular techniques. The use of simulators could be an alternative educational tool, but some of them are cumbersome, expensive to implement, or lacking in realism. The aim of this study is to evaluate a reusable low-cost 3-dimensional printed training model we developed for aneurysm clipping.

    Surgery for high-grade gliomas in a developing country: survival estimation using a simple stratification system
    (ELSEVIER SCIENCE INC, 2008) Lorenzoni, Jose; Torrico, Alejandro; Villanueva, Pablo; Gederlini, Alessandra; Torrealba, Gonzalo
    Background: In spite of great technological advances in diagnostic and therapeutic tools, Survival in patients with HGG has not changed significantly in the last years. Judicious management in each case needs Survival estimation after surgery. We used a simple stratification system evaluating the histology, patient's age, and the KPS.
