Clinical Application of 3D-DSA and Dyna-CT in Intracranial Stent Placement
Objective To explore the clinical application of three-dimensional DSA angiography(3D-DSA)and C-arm rotation and tomographic reconstruction technology(Dyna-CT)of digital flat plate imaging machine in patients undergoing intracranial stent implantation.Methods A total of 92 patients with intracranial artery stenosis admitted to Zhongshan Hospital affiliated with Xiamen University from January 2019 to June 2020 were selected.All patients underwent intracranial stent implantation and were divided into a control group(n=38 cases)and an observation group(n=54 cases).The control group was guided by 3D-DSA,while the observation group was guided by Dyna-CT.A12 month outpatient follow-up was conducted after surgery to compare the modified Rankin scale(mRS)scores,surgical success rates,complications,stent restenosis,and plaque detection rates between the two groups.Results The observation group had lower mRS scores and shorter stent reconstruction time at 4,8,and 12 months after surgery compared to the control group(P＜0.05);The preoperative planning and observation of stent surface images in Dyna-CT observation group were consistent with intraoperative findings,with a surgical success rate of 83.33％,which was higher than 63.16％in the control group(P＜0.05);There was no statistically significant difference in the incidence of perioperative complications between the two groups(P＞0.05);The observation group underwent 12 months of outpatient follow-up after surgery,and the detection rate of plaque in stent restenosis and vascular stenosis sites in patients was lower than that in the control group(P＜0.05).Condusion Dyna-CT used in intracranial stent implantation can improve patient symptoms,shorten the time required for stenting,and help improve the success rate of surgery.It does not increase the incidence of complications and can reduce the detection rate of plaque in vascular stenosis sites.It is worth promoting and applying.
