摘要: Object Management of unruptured intracranial aneurysms remains controversial in neurosurgery. The contribution morphological parameters has not been included the treatment paradigm a systematic manner or for any particular aneurysm location. authors present large sample middle cerebral artery (MCA) that were assessed using variables to determine associated with rupture. Methods Preoperative CT angiography (CTA) studies evaluated Slicer software generate 3D models and their surrounding vascular architecture. Morphological examined each model 5 already defined literature (aneurysm size, aspect ratio, angle, vessel size ratio) 3 novel (flow distance genu, parent-daughter angle). Univariate multivariate statistical analyses performed significance. Results Between 2005 2008, 132 MCA aneu...
