    Alternative cost-effective method to record 3D intra-operative images: A technical note
    (2014) BARONE, Damiano Giuseppe; BAN, Vin Shen; KIROLLOS, Ramez W.; TRIVEDI, Rikin A.; BULTERS, Diederik O.; RIBAS, Guilherme Carvalhal; SANTARIUS, Thomas
    The educational value of stereoscopic imaging in neurosurgical training has increasingly been appreciated and its use increased during the last decade. We describe a technique that we developed to acquire and reproduce intra-operative stereoscopic images.

    Head positioning for anterior circulation aneurysms microsurgery
    (2014) CHADDAD-NETO, Feres; DORIA-NETTO, Hugo Leonardo; CAMPOS-FILHO, Jose Maria de; RIBAS, Eduardo Santamaria Carvalhal; RIBAS, Guilherme Carvalhal; OLIVEIRA, Evandro de
    Objective: To study the ideal patient's head positioning for the anterior circulation aneurysms microsurgery. Method: We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the patient's head was positioned accordingly to the aneurysm location and the results from the cadaveric study. The effectiveness of the position was noted. Results: We could determine mainly two patterns for head positioning for the anterior circulation aneurysms. Conclusion: The best surgical exposure is related to specific head positions. The proper angle of microscopic view may minimize neurovascular injury and brain retraction.
