Planning and Sizing with OsiriX/Horos
It is known that endovascular aneurysm repair (EVAR) requires a precise deployment of the graft and so the anatomical and morphological characteristic study of the aorta and its branches is mandatory. The increase of endovascular surgeons’ interest on tomography image edition through software is marked specially when the increasing frequency of these procedures and its complexity have impelled surgeons to face additional and successive risk to occupational radiation exposure. Thus, a meticulous study of the angio-CT during EVAR preparation allows the reduction of unnecessary radiation exposure, as it also reduces consecutive image acquisition and contrast use (that may be related to renal overload in susceptible patients). Although some studies propose effective strategies to optimize the procedure, they rely on the use of additional specific and advanced equipment, available only in major centers. As an alternative, a simpler technique through image manipulation on the software OsiriX/Horos, aiming to reduce both exposures, is presented.
