Clinical analysis of 103 cases' intracranial aneurysms

Objective To investigate clinical manifestation,diagnosis,treatment of intracranial aneurysm and summarize the experience.Methods Retrospective analysis of 103 cases' intracranial aneurysms admitted in our hospital from Oct-2007 to Mar-2010 were carried out to study onset,clinical manifestation and image data.Results 103 patients were identified 126 intracranial aneurysms,in which 84 patients were single and 19 were multiple.15 patients had 2 aneurysms each and 4 patients had 3 aneurysms each.One patient combines arteriovenous malformation,one combines dissecting aneurysm of extracranial carotid artery and one combines Moyamoya disease.There were 15 cases of unruptured intracranial aneurysms,accounting for 14.6%(15/103).Posterior communicating artery aneurysms were the most common,accounting for 32.5%(41/126).Diameter of aneurysm was mostly found in 2.0-4.9 mm,accounting for 61.9%(78/126),which the minimum is 1.5mm and the maximum is 35mm.Conclusions To apply appropriate and timely diagnostic imaging of intracranial aneurysm and endovascular treatment in time can significantly reduce mortality and morbidity.
