Type II Abernethy malformations, characterized by side-to-side portosystemic shunting with preserved intrahepatic portal venous system, have been treated with shunt closure surgically and endovascularly. Three-dimensional printing has been used to develop highly accurate patient-specific representations for surgical and endovascular planning and intervention. This innovation describes 3-dimensional printing to successfully close a flush-oriented type II Abernethy malformation with discrepant dimensions on computed tomography, conventional venography, and intravascular ultrasound, using a 12-mm Amplatzer atrial septal occluder device.
II型阿伯内西畸形的特征是肝内门静脉系统保留的左右侧门体分流，已通过手术和血管内方法进行分流闭合治疗。三维打印已被用于开发高度精确的患者特异性模型，用于手术和血管内规划及干预。本创新描述了使用三维打印，利用一个12毫米的Amplatzer房间隔封堵器装置，成功闭合了在计算机断层扫描、传统静脉造影和血管内超声上尺寸不一致的平流式II型阿伯内西畸形。
