Abstract：ObjectiveTo analyze the application value of CTA imaging in the risk assessment of cystic intracranial aneurysm rupture.MethodsFrom January 2012 to December 2015,200 patients with cystic aneurysms were enrolled as research objects.According to rupture of aneurysms,they were divided into rupture group(n＝97)and non-rupture group(n＝103).The CTA technique was used to detect the length of aneurysm and width of aneurysm neck,AR value,etc.The condition of ascus was observed and the correlation of CTA inspection result and IA rupture was analyzed.ResultsIn the rupture group,the length of aneurysm and width of aneurysm neck,AR,SR,and aneurysm tilt angle were all significantly higher than those in the non-rupture group(P＜0.05).In the rupture group,44 cases were occurred with ascus and the incidence was 45.36%,while in the non-rupture group,14 ones were occurred with ascus and the rate was 13.59%.The incidence of ascus in the rupture group was higher than that in the control group(P＜0.05).ConclusionThe rupture of intracranial aneurysms is related with the length of aneurysm,the width of aneurysm neck,AR value,SR value,aneurysm tilt angle,and the condition of ascus.Longer in the aneurysm,wider in the aneurysm neck,and the occurrence of ascus all will increase the risk of rupture,to which should be pain great attention in clinic.
