Abstract： Objective To investigate the effect of 3D-digital subtraction angiography(DSA)combined with Innova-computed tomography(CT)on postoperative evaluation of intracranial stent-assisted coil embolization of aneurysms.Method The clinical data of 104 patients admitted to the Third Clinical College of Hefei of Anhui Medical University/the Third People's Hospital of Hefei from January 2021 to December 2022 were collected,who underwent follow-up examinations after intracranial stent-assisted aneurysm coil embolization.All patients underwent 3D-DSA and Innova-CT scanning.The postoperative embolization degree of intracranial aneurysm,stent opening,as well as the image quality of the reconstructed images were evaluated by two neurointerventional physicians.Result The reconstructed images of 104 patients who underwent follow-up examinations after intracranial stent-assisted aneurysm coil embolization were analyzed comprehensively and the accurate postoperative evaluation was obtained.There were statistically significant differences in the postoperative embolization degree and stent opening of intracranial aneurysm evaluated by two neurointerventional physicians(P<0.05).The innova-CT image support wire developed clearly,while the spring ring metal artifact was not obvious,and the image quality was significantly improved.The comparison of image quality between 3D-DSA and Innova CT showed statistically significant difference(P<0.05).The Kappa test results showed that the Kappa values of two neurointerventional physicians evaluating the postoperative intracranial aneurysm embolization degree,stent opening,platinum marker points,nickel titanium metal wires,and coil metal artifacts were all≥0.75,indicating high consistency.Conclusion Innova-CT has unique advantages in intracranial stent-assisted aneurysm coil embolization,especially the display of stent opening,which is a supplementary examination for 3D-DSA,making the examination more perfect,and playing a guiding role in the evaluation of intracranial stent-assisted coil embolization of aneurysms.
