Abstract
Objective:To analyze application value of navigation and positioning of color fusion technique of three-dimensional(3D)digital subtraction angiography(DSA)in interventional surgery for patients with intracranial aneurysms,and to explore influencing factors of prognosis.Methods:From November 2021 to January 2025,a total of 221 patients who underwent intervention surgery for intracranial aneurysm at Anhui No.2 Provincial People's Hospital were selected,and they were divided into control group(n=107)and study group(n=114)according to different navigation methods during surgery.In order to control confounding bias,8 baseline data(gender,age,marital status,education level,hypertension,medical history,diabetes history,smoke history and drink alcohol history)were selected as covariate.After propensity score matching was adopted to conduct nearest marching as ratio of 1 to 1,each group enrolled 52 patients,and the characteristics of baseline should be balanced and comparable.The control group adopted two-dimension(2D)path map to conduct navigation,while the study group adopted 3D DSA color fusion technique to assist navigation.The total duration of surgery,the time-consuming of microcatheter guidance,and the duration of X-ray fluoroscopy were compared between the two groups,and the used dosage of contrast agent,radiation dose,air kerma(AK),dose-area product(DAP),surgical complications and the risk factors of poor prognosis were compared and analyzed.Results:The total duration of surgery,the time-consuming of microcatheter guidance,and the duration of X-ray fluoroscopy of the study group were respectively(92.34±10.26)min,(5.76±1.82)min and(38.74±4.26)s,all of which were shorter than those[(101.54±9.25)min,(8.23±2.31)min and(51.27±5.49)s]of the control group,and the differences were statistically significant(t=4.803,6.057,13.003,P<0.05).The used dosage of contrast agent of the study group was significantly less than that of the control group,and the DAP and AK of radiation dose were also significantly less than those of the control group(t=7.442,10.123,23.910,P<0.05).The difficulty of intraoperative guidance of the study group was lower than that of the control group,and the difference was statistical significance(Z=8.131,P<0.05).There was no significant difference in the incidence of complications between the two groups(P>0.05).The binary logistic regression analysis showed that the timing of surgery,Hunt-Hess grade and Fisher grade were the risk factors that caused poor prognosis(OR=5.397,5.765,6.786,P<0.05),respectively.Conclusion:Using 3D DSA color fusion technique has higher auxiliary application value in navigation and positioning of interventional surgery for patients with intracranial aneurysms.关键词
