- 摘要:
- 目的 初步总结心脏3D打印模型在不同先天性心脏病手术模拟矫治中的临床应用体会。方法 以2016年12月至2020年8月湖南省人民医院48例先天性心脏病患儿为研究对象（其中15例法洛四联症患儿为3D打印组），收集这15例患儿的心脏CT血管造影（computed tomography angiography，CTA）资料，制作心脏3D打印模型，外科医师在模型上进行手术模拟讨论后再实施真实手术，并比较模拟手术与真实手术的操作体会；另取12例法洛四联症常规手术患儿作为对照组，与3D打印组手术时间进行比较。结果 所有患儿手术顺利，无一例手术过程中死亡；3D打印组患儿真实手术与术前心脏3D打印模型模拟相关性满意，4例患儿因心脏3D打印模型稍高估了肺动脉瓣瓣环直径而修改手术方式；3D打印组法洛四联症手术的主动脉阻断时间少于对照组[（47.47±9.42） min比（55.75±9.00） min，P=0.029]。结论 心脏3D打印模型能为多种先天性心脏病手术的讨论、模拟提供高仿真平台，通过详细手术模拟能有效缩短真实手术时间。
- Abstract:
- Objective To employ three-dimensional (3D) printing model for simulating heart correct operation and summarizing its preliminarily experience for improving the surgical outcomes of various congenital heart diseases.Methods Cardiac computed tomography angiography (CTA) data of 48 children with various congenital heart diseases were selected for constructing the corresponded 3D printing models.Based on these 3D models, surgeons discussed surgical plans and simulated operative skills preoperatively.The process of real corrective procedure and the simulation were compared.Another 12 cases of tetralogy of Fallot undergoing routine surgery were selected as control group and operative durations were compared.Results The operative findings correlated well with the cardiac 3D models and the correlation between real operation and preoperative simulation of 3D printing model was satisfactory.Only 4 children’s cardiac 3D printing model slightly overestimated the diameter of pulmonary valve ring.Aortic clamp time was less in 3D group than that in control group[(47.47±9.42) vs.(55.75±9.00) min, P=0.029].Conclusion Cardiac 3D printing model may provide a feasible simulation platform for discussing and simulating surgical procedures.It can shorten operative duration and improve surgical outcomes.
