Multislice CT Angiography of Cerebral Aneurysms in Nontraumatic Subarachnoid and Intraparenchymal Haemorrhage

Purpose: The aim of this study was to assess the usefulness of multislice computed tomography angiography (CTA) in identifying and evaluating cerebral aneurysms in patients with non traumatic subarachnoid and intraparenchymal hemorahge by comparing it with intraoperative findings.Material and methods: Between June 2011 and April 2012, fifty patients were included in our study group, they were 38 males and 12 females, their ages ranged from 30 to 60 years (mean 45 years). Each patient in our study with a CT diagnosis of nontraumatic subarachnoid hemorrhage (SAH) underwent CTA. The CTA study was performed with a 64 multidetector device (General electric, lightspeed 64). CTA were evaluated to assess the presence of aneurysms and their morphological characteristics.Results: We identified 40 aneurysms in the anterior circulation and 10 in the posterior circulation. There were 18 giant aneurysms, 12 large aneurysms, 10 medium aneurysms, 5 small aneurysms and 5 very small aneurysms.Conclusion: CTA is fast and relatively noninvasive, and it is sensitive in detecting and evaluating intracranial aneurysms. This study confirms the value of CTA as the primaryimaging technique in subarachnoid haemorrhage.
