Value of 3D digital subtraction angiography in neurointerventional surgery for ruptured intracranial aneurysm
Objective To explore the value of 3D digital subtraction angiography(DSA)in neurointerventional surgery for ruptured intracranial aneurysm.Methods Clinical data of 176 patients with ruptured intracranial aneurysms who underwent neurointerventional surgery at No.904 Hospital of Joint Logistics Support Force from January 2020 to March 2023 were retrospectively analyzed.All patients were diagnosed with intracranial aneurysms through CT angiography and underwent 2D and 3D DSA examinations.The display of distal blood vessels and branches,detection rates of aneurysms,display of the relationship between the aneurysm neck and parent artery,and display of the vessels penetrated by aneurysms were recorded.Results There was no significant difference between the 2D-DSA and 3D-DSA technologies in displaying distal blood vessels and branches(P>0.05).The detection rate of aneurysms by 3D-DSA was 99.43%(175/176),which was significantly higher than that by 2D-DSA(89.20%,157/176),with statistical difference(P<0.05).The detection rate of common cystic aneurysm by 3D-DSA was significantly higher than that by 2D-DSA(66.86%vs 47.16%,P<0.05).Unclear relationship between the aneurysm neck and parent artery was found in 108 patients(61.36%)by 2D-DSA and in 68 patients(38.64%)by 3D-DSA(13.64%),and there was significant difference in the detection rate of the unclear relationship between 2D-DSA and 3D-DSA(P<0.05).No penetrating blood vessels were detected by 2D-DSA,while 20(11.36%)penetrating blood vessels were detected by 3D-DSA(P<0.05).Conclusion 3D-DSA technique can improve the detection rate of aneurysms,and has high diagnostic value for the morphology of aneurysms and their relationship with the parent artery.
