目的:总结在DSA检查时造影剂应用方面的体会和经验。材料和方法:共行DSA 2560人次,其中男性1850例,女性710例,年龄5个月到85岁,包括动脉和静脉造影。其中用离子型造影剂2100人次,非离子型造影剂460人次。结果:造影剂注射次数1—12次不等,平均4次,造影剂用量10—180ml,平均58ml。DSA质量评价:优等为85％,中等为13％,差为2％。副反应:离子型造影剂组和非离子造影剂组分别为4.8％和1.4％。无一例死亡。结论:对不同部位进行造影时应选择合适的造影剂,既考虑安全又考虑到病人的经济情况,选择适当的流速流量,既显示血管及其病变,又减少过敏反应及不适感的发生。
OBJECTIVE: To summarize the experience and experience with contrast media applications at DSA. Materials and Methods: A total of 2560 DSA patients were enrolled, including 1850 males and 710 females, aged 5 months to 85 years old, including arterial and venous angiography. Among them, there were 2100 ion-contrast agents and 460 non-ionic contrast agents. Results: The times of injection of contrast agent ranged from 1 to 12 times with an average of 4 times. The contrast agent dosage was 10-180ml with an average of 58ml. DSA quality assessment: excellent 85%, moderate 13%, poor 2%. Side effects: ionic contrast agent group and non-ionic contrast agent group were 4.8% and 1.4%. No one died. CONCLUSIONS: Different contrast media should be selected for different parts. Considering the safety of the patients and the economic situation of the patients, choosing appropriate flow rate and flow rate can not only show the vessels and their pathological changes, but also reduce the occurrence of allergic reactions and discomfort.
