dc.descriptionIn the past few years, the increase of endovascular surgeons' interest on tomography image edition through softwares is marked specially when it concerns to its use on preoperatory study for endovascular aneurysm repair. It is presumed that the bigger the number of informations extracted from the tomography exam and its three-dimensional reconstruction, the smaller is the need of patient's exposure to contrast, as well as the its exposure and the surgical team to radiation. Concepts of image manipulation on the OsiriX software with volume reconstruction of tridimensional tomographic scans of virtual fluoroscopy were used. Methods: Through manipulation of multi-slice tomography images under three-dimensional reconstruction on software, it was able to modify values of the exam's dose-irradiated distribution. These volume reconstruction presets were saved as Virtual Fluoroscopy, reproducible upon any OsiriX platform. It was able to construct a biplanar image appearing to the patient's operatory fluoroscopy. When compared to the intraoperatory angiography, the images were alike. Discussion: Dose-irradiated distribution data manipulation allowed to visualize as opaque bone surfaces and transparent lowdose radiation's areas (viscerae). Thus, under previously marked renal arteries, it was possible to predict it's anatomical positioning related to visualization under real fluoroscopy. Foretelling the better positioning of the C-arm through this technique enables to obtain images with the minimum influence of parallax effect. It is believed that it supports to assess the renal arteries topographic positioning on a bi-dimensional intraoperatory image. The need of frequent angiographies to localize the renal arteries is reduced, decreasing the exposure to contrast on vulnerable patients.
