Abstract:
Objective:To analyze the influencing factors of contrast agent extravasation in coronary CT angiography(CTA)examination,and to formulate intervention measures.Methods:A retrospective selection of data from 583 patients who underwent coronary CTA at Peking University People's Hospital from January to December 2023 was conducted.Logistic regression was used to analyze the patients'general information and injection protocols,and the risk factors of contrast agent extravasation were determined.Results:Among the 583 patients included,11 patients had contrast agent extravasation during CTA examination,with an extravasation rate of 1.887%.The contrast agent was all extravasated into the subcutaneous tissue,and the CT value did not reach the trigger criteria.Gender,education level,diabetes mellitus,history of intravenous chemotherapy,age,weight,body mass index(BMI),injection rate and injection dose were all associated with the occurrence of contrast agent extravasation,the difference was statistically significant(x2=18.911,7.563,16.567,4.279,t=3.576,3.244,1.865,4.297,6.532,P<0.05).Age,education level,history of intravenous chemotherapy,diabetes mellitus,injection rate and injection dose were risk factors for contrast agent extravasation in coronary CTA(OR=1.008,1.372,1.029,5.092,0.975,1.421,P<0.05).Conclusion:Factors such as low education level,advanced age,history of intravenous chemotherapy,high injection rate and large injection dose can increase the risk of contrast agent extravasation in coronary CTA examination.Radiology staff should closely monitor high-risk patients,strengthen monitoring of intravenous injection of contrast agents for coronary CTA examination,and reduce the occurrence of contrast agent extravasation.
