Abstract：Objective To analyze the influencing factors of contrast medium leakage after CT enhanced scan. Methods Data of 51 patients with contrast medium leakage after CT enhanced scan in Jiangsu Provincial People’s Hospital (hereinafter referred to as “our hospital”) from January 2019 to May 2021 were retrospectively collected and included in the occurrence group. Data of 51 patients without contrast medium leakage after CT enhanced scan in our hospital during the same period were collected and included in the non-occurrence group. Baseline data of the two groups were recorded and analyzed, scanning sites, injection sites, and contrast medium injection rates of the two groups were statistically analyzed, and logistic regression model was used to analyze the influencing factors of contrast medium leakage after CT enhanced scan. Results The proportion of patients with combined hypertension or diabetes mellitus or malignant tumor, forearm vena injection, and contrast medium injection rate were higher than those in the non-occurrence group, and the differences were statistically significant (P ＜ 0.05). Multivariate analysis showed that hypertension, diabetes mellitus, malignant tumor, forearm vena injection and rapid injection rate were independent risk factors for contrast medium leakage after CT enhanced scan (OR ＞ 1, P ＜ 0.05). Conclusion The contrast medium leakage after CT enhanced scan may be affected by a variety of factors, and the injection rate should be strictly controlled according to the specific situation of patients. For patients with the above risks, the contrast medium leakage should be closely observed and treated in time to ensure the quality of CT enhanced scan and the safety of patients’ lives.
