摘　　要：探讨快速成型技术在Standford A型主动脉夹层治疗中应用的可行性。对5例Standford A型主动脉夹层患者行主动脉CTA扫描,通过MIMICS 16.0软件进行三维重建,快速成型制作出与实体1:1大小的主动脉夹层模型,根据模型充分了解患者主动脉病变情况,为主动脉夹层患者制定"个体化"的治疗方案,并在模型上模拟手术,在实际操作中取得了较好的手术效果,患者术后无任何并发症,均痊愈出院。快速成型模型使Standford A型患者的术前准备更充分,能够提高主动脉夹层手术效率与精准度,并能在腔内治疗中指导支架近端的精准锚定。To explore the feasibility of rapid proto - typing （RP） technology in the treatment of Standford type A aortic dissection. 5 patients with Standford type A aortic dissection received computed tomography angiography （CTA） of their aortas. The CTA images were then processed by 3D reconstruction with MIMICS16.0 in order to create aortic dissection models through RP technology based on real patient aorta size with a ratio of 1 ： 1. Accord- ing to these models, the surgeons were able to fully understand the aortic diseases of patients, thus establish indi- vidualized treatment strategies for each patient. Besides, the surgeons simulated operations on the models, which helped them achieve better results in real surgery. These patients experienced no post - operative complications and were discharged from hospital with recovery. In conclusion, RP technology can provide adequate preoperotive prep- arations for patients with Standford type A aortic dissection, improve operation efficiency and accuracy in aortic dis- section and guide precise proximal anchoring of stents during intracavitary therapy.
