Objective To explore the application value of computerized tomography angiography(CTA)three-dimensional visualization assisted cerebral aneurysm intervention.Methods A total of 74 patients with cerebral aneurysm who were admitted to the Pingxiang People′s Hospital from November 2018 to June 2020 were selected as the research subjects.They were divided into an observation group of 37 cases and a control group of 37 cases according to the alternate grouping method.Both groups received intracranial aneurysm intervention.The control group was assisted by three-dimensional digital subtraction angiography(3D-DSA),and the observation group was assisted by CTA three-dimensional visualization.The operation time,radiation dose and Glasgow outcome scale(GOS)score at 3 months after the operation were compared between the two groups,and the complications and recurrence of the two groups were compared.Results There was no statistically significant difference in the operation time,radiation dose or GOS score of the two groups of patients after 3 months(P>0.05).The incidence of thrombus,aneurysm rupture and postoperative aneurysm recurrence rate were compared between the two groups,and the differences were not statistically significant(P>0.05).The incidence of postoperative puncture point bleeding in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion Compared with cranial 3D-DSA assisted cerebral aneurysm intervention,the use of CTA three-dimensional visualization assisted treatment can greatly reduce the incidence of postoperative puncture point bleeding,and the operation time,radiation dose and prognosis are equivalent,without increasing intraoperative thrombosis,the incidence of aneurysm rupture or postoperative aneurysm recurrence rate.
