Value of multidetecter computed tomography angiography in screening intracranial aneurysm of the acute sontaneous subarachnoid hemorrhage

Objective To investigate the multidetecter computed tomography angiography value of screening intracranial aneurysm in the acute spontaneous subarachnoid hemorrhage.Methods The material of 20 months CT diagnosis in 46 patients with spontaneous SAH were reviewed retrospectively.They were detected by MSCTA from acute onset to a week.The results of MSCTA were compared with DSA and neurosurgery.Results 46 cases,MSCTA found positive 38 cases,a causal leave negative,The sensitivity and specificity of detecting aneurysm was 97.44% and 100% ;Positive cases showed occlusion form size,tumor neck,load tumor artery and peripheral vascular anatomy relationship clearly.Conclusion MSCTA is safe,quick,noninvasive,reliable cerebrovascular imaging technology.In acute spontaneous SAH,It is a cerebral aneurysm preferred screening method,at the same time it can also effectively evaluate aneurysmal situation,for clinical follow-up processing to provide adequate basis.
