Abstract

Aim: Intracranial aneurysms are the leading cause of non-traumatic subarachnoid hemorrhage which can have devastating consequences. Imaging techniques improved greatly and now play a very important role in detection and management of aneurysms. The aim of this study was to share our experience with applications of three-dimensional reconstructions from computed tomography angiography images for diagnosis and surgical planning of brain aneurysms. Material and methods: We retrospectively analyzed a series of 244 aneurysms in 210 patients treated from January 2019 to December 2019 in a specialized neurosurgical center. We used Toshiba Aquilion 32 slice CT scanner for image acquisition and Vitrea software for three dimensional reconstructions. Results: we found 244 aneurysms and the anterior communicating artery was the most frequent aneurysm location, followed by middle cerebral artery, the posterior communicating artery and internal carotid artery. Maximum Intensity Projection and volume rendering techniques provided for the neurosurgeons and neurosurgery residents a very good detection and assessment of aneurysm morphology with its proximal and distal vessels. Conclusions: Postprocessed images and three-dimensional reconstruction should be used more often in neurosurgery in order to better understand the morphologic details and for a better treatment planning of intracranial aneurysms.
