OBJECTIVE Our objective is to present and asses the utility of three-dimensional (3D) intraoperative imaging as a teaching method for anterior circulation aneurysm surgery. METHODS The senior author's experience in anterior circulation aneurysm surgery during a 28-month period was documented and processed as 3D images and compared with two-dimensional(More)
In this paper Adams-Bashforth approximations were employed for sampled-data modeling of a large class of vehicle dynamics in many degrees of freedom. The problem of path tracking and regulation with geometric and kinematic specifications on the reference paths was focused afterwards. An approach to model-based controller design was presented based on a(More)
OBJECTIVE To make a description of the anatomy of fontanelles and to update what is currently known about their applications. METHOD 7 cadaveric heads, 2 dry skulls and 2 frontal bones of foetus were used, and 48 anterior fontanelles from paediatric patients with or without associated pathology were examined. Surgical cases and neurosonography were also(More)
This paper is concerned with the study of nonlinear oscillations in servotracking control systems for the teleoperation of ROVs subject to strong currents and harmonic waves. Particularly, the case of variable cable length during tactics on the sea bottom such as sea bottom scanning and systematic grab sampling are analyzed. The route to chaos from(More)
OBJECTIVE This study sought to show and analyze the main authors' experience (P.R. and J.M.C.) in previously coiled aneurysm surgery as an emerging challenge in today's neurosurgical practice. METHODS Twelve female and 8 male patients, whose ages ranged from 32 to 56 years (average 43.5), underwent surgery between April 2009 and September 2012 in 2(More)
UNLABELLED Epineural stitches are a means to avoid tension in a nerve suture. We evaluate this technique, relative to interposed grafts and simple neurorraphy, in a rat model. METHOD Twenty rats were allocated to four groups. For Group 1, sectioning of the sciatic nerve was performed, a segment 4 mm long discarded, and epineural suture with distal(More)
