- W2383810077 abstract "Objective:To explore the value and clinical application of 64 multi-slice CTA(MSCTA) for etiological diagnosis of acute spontaneous subarachnoid hemorrhage.Methods:69 patients,who were clinically diagnosed as spontaneous subarachnoid hemorrhage,were examined by 64 MSCTA and by DSA or operation.The results of CTA were compared with those of DSA or operation.Results:In the group of 69 patients,a total of 59 aneurysms were diagosed by CTA in 53 cases,including 5 cases of multiple,DSA found 59 aneurysms in 53 cases,CTA missed one aneurysm and misdiagnosed one;5 cases diagnosed as arteriovenous malformation(AVM) were confirmed by DSA and surgery;besides,three cases of moyamoya disease were confirmed by DSA;and 8 cases were negative.MSCTA etiological diagnosis of the overall sensitivity,specificity,positive predictive value and negative predictive value of 64 multi-slice CTA(MSCTA) for etiological diagnosis of acute spontaneous subarachnoid hemorrhage were 98.6%,88.9%,98.6%,88.9%;respectively.There was no significant difierence in the dome to the neck ratio(D/N ratio) and the long axis between DSA and MSCTA(P0.05),but some conclusion may exist that the overall evaluation of the D/N was too low.It was easy to misdiagnose the narrow-neck aneurysms as wide-necked aneurysms.Conclusion:64 slice CTA can accurately and quickly evaluate patients with acute spontaneous SAH,provide a scientific basis for clinical diagnosis and treatment,and decrease the death and disability rate of patients." @default.
