摘　　要：目的:探讨基于CT血管造影(CTA)数据源3D打印技术联合多媒体教学在腹主动脉扩张性疾病教学中的应用效果。方法:选择2020年4-10月蚌埠医学院第一附属医院血管外科硕士、规培生及本科实习生共60人,采用随机数表法抽样分组,双盲法,根据随机数字分配法将所有入选者分为观察组和对照组,各30人。选取于院内由于腹主动脉扩张性疾病进行血管介入治疗的典型病例4例。4例病例术前均进行过CTA检查,依据CTA数据采用3D打印技术制作1∶1实体模型。对照组采用传统多媒体教学方法,观察组在多媒体教学的同时联合基于CTA数据源3D打印技术辅助教学进行学习。结果:观察组总分高于对照组(P<0.05),且观察组在腹主动脉解剖方面测试成绩、腹主动脉扩张性疾病介入治疗方案选择和介入治疗适应证及禁忌证方面测试成绩均明显高于对照组,差异有统计学意义(P<0.05);观察组学生对血管系统解剖结构的了解、对主动脉扩张性疾病特征的了解、对腔内手术器具和过程的了解、学习的主动性和自信心均优于对照组,差异有统计学意义(P<0.05);观察组满意度为90.00%,高于对照组的60.00%(P<0.05)。结论:基于CTA数据源3D打印技术联合多媒体教学在腹主动脉扩张性疾病教学中,能明显提高学生的学习成绩,提高满意度,具有良好的应用效果,适合推广。Objective:To explore the application effects of 3D printing technology combined with multimedia teaching based on CT angiography(CTA)data source in the teaching of abdominal aortic dilatation diseases.Methods:From April to October 2020,a total of 60 doctors with master degree in vascular surgery,regulatory affairs trainee and undergraduate interns from the First Affiliated Hospital of Bengbu Medical College were selected,and divided into the observation group and control group according to the random number allocation method(30 cases in each group).Four typical abdominal aortic dilatation cases treated with vascular interventional therapy in hospital were selected,and detected using CTA before operation.The 1∶1 solid model was made by 3D printing technology according to CTA data.The control group was taught with the traditional multimedia teaching method,while the observation group was taught with multimedia instruction combined with 3D printing technology based on CTA data source.Results:The total score in observation group was higher than that in control group(P<0.05).The test scores of abdominal aortic anatomy,interventional therapy for dilated aortic diseases,indications and contraindications in observation group were significantly higher than those in control group(P<0.05).The understanding the anatomical structure of vascular system,understanding the characteristics of aortic dilated disease,understanding the instruments and procedures of endovascular surgery,learning initiative and confidence in observation group were better than those in control group(P<0.05).The satisfaction of the observation group was 90.00%,which was higher than that of the control group(60.00%)(P<0.05).Conclusions:The 3D printing technology combined with multimedia teaching based on CTA data source in the teaching of abdominal aortic dilatation disease can significantly improve the students′academic performance and satisfaction.It has a good application effect,and is suitable for promotion.
