Rapid prototyping technology is used to fabricate three-dimensional (3D) brain arteriovenous malformation (AVM) models and facilitate presurgical patient communication and medical education for young surgeons.
Two intracranial AVM cases were selected for this study. Using 3D CT angiography or 3D rotational angiography images, the brain AVM models were reconstructed on personal computer and the rapid prototyping process was completed using a 3D printer. The size and morphology of the models were compared to brain digital subtraction arteriography of the same patients. 3D brain AVM models were used for preoperative patient communication and young neurosurgeon education.
Two brain AVM models were successfully produced. By neurosurgeons' evaluation, the printed models have high fidelity with the actual brain AVM structures of the patients. The patient responded positively toward the brain AVM model specific to himself. Twenty surgical residents from residency programs tested the brain AVM models and provided positive feedback on their usefulness as educational tool and resemblance to real brain AVM structures.
Patient-specific 3D printed models of brain AVM can be constructed with high fidelity. 3D printed brain AVM models are proved to be helpful in preoperative patient consultation, surgical planning and resident training.
运用快速成型技术制作三维（3D）脑动静脉畸形（AVM）模型，以促进术前医患沟通及为年轻外科医生提供医学教育。
本研究选取了两例颅内AVM病例。利用3D CT血管造影或3D旋转血管造影图像，在个人电脑上重建脑AVM模型，并使用3D打印机完成快速成型过程。将模型的大小和形态与同一患者的脑数字减影血管造影进行比较。3D脑AVM模型用于术前医患沟通及年轻神经外科医生的教育。
成功制作出两个脑AVM模型。经神经外科医生评估，打印出的模型与患者实际的脑AVM结构高度相似。患者对针对其自身的脑AVM模型反应积极。来自住院医师培训项目的20名外科住院医师测试了脑AVM模型，并对其作为教育工具的实用性以及与真实脑AVM结构的相似性给予了积极反馈。
可以高保真地构建患者特异性的3D打印脑AVM模型。事实证明，3D打印脑AVM模型有助于术前患者咨询、手术规划及住院医师培训。
