ABSTRACT
Objective To explore the clinical value of 3-dimensional digital subtraction angiography(3D-DSA)in the diagnosis and therapy of intracranial aneurysms.Methods 2-dimensional digital subtraction angiography (2D-DSA)and 3D-DSA was performed respectively on 1 53 patients,including 1 5 1 cases with spontaneous subarachnoid hemorrhage (SAH),1 case with headache and 1 case with cerebral infarction;Meanwhile,to compare the difference in diagnosis of intracranial aneurysms between 2D-DSA and 3D-DSA.Results 1 12 patients(125 pieces)with intracranial aneurysms were detected on 2D-DSA,its detecting rate was 73.2%(1 12/1 53 );136 patients(1 52 pieces)with intracranial aneurysms were detected on 3D-DSA,its detecting rate was 88.9%(136/1 53)(χ2 =12.254,P <0.05).The displaying rate of 3D-DSA for the relationship between carrying tumor artery and aneurysms and the necks of aneurysms was 100%(1 52/1 52),however,the displaying rate of 2D-DSA for that was 61.6%(77/125)(χ2 =63.993,P <0.05). Conclusion 3D-DSA can improved the diagnostic accurate rate of intracranial aneurysms,it is important in chosing the therapeutic regimen.
