ABSTRACT
Objective: To research three-dimensional computed tomography angiography (3D-CTA) combined three-dimensional digital subtraction angiography (3D-DSA) in the diagnosis of intracranial aneurysms. Methods: 3D-CTA and 3D-DSA were performed in 27 cases with Highly suspected in patients with intracranial aneurysms, And compared with the final outcome of surgery. To evaluate 3D-CTA and 3D-DSA in the detection rate of aneurysms, three-dimensional shape and spatial relations ability to display. Research 3D-CTA combined 3D-DSA in the diagnosis of intracranial aneurysms. Results: Twenty-seven cases of suspected patients, 25 cases of surgical treatment of confirmed aneurysms, 28 aneurysms found. 3D-CTA and 3D-DSA rate of aneurysms was no significant difference. 3D-CTA of the aneurysm can be accurately detected clearly shows its three-dimensional shape and spatial relationship with the surrounding skull, 3D-DSA for aneurysm neck, the tumor and the aneurysm and parent artery relationship shows clear and accurate. Conclusion: Imaging of intracranial aneurysm diagnosis, 3D-CTA and 3D-DSA have their respective advantages, combined two methods can improve the detection rate of aneurysms. 3D-CTA combined 3D-DSA have support of design for operation.
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.
ABSTRACT
Objective To evaluate the application of 3D DSA in diagnosis of intracranial aneurysm. Methods Conventional DSA and 3D DSA were performed in 15 cases with subarachnoid hemorrhage. Results Of 15 cases, by 3D DSA, 12 ones were diagnosed as intracranial aneurysm, and the remaining 3 ones were suspected, while 7 ones could be diagnosed by conventional DSA. Conclusion 3D DSA can improve the diagnosis of intracranial aneurysm.
