OBJECTIVE: To attempt to produce highly accurate three-dimensional (3D) printed models of @entity449 models aid complicated preoperative planning in endovascular repair procedures. METHODS: From October 2012 to May 2014, six @entity1 with complicated @entity449 (one aortic arch @entity439 , one @entity2334 and four juxtarenal @entity1028 ) accepted preoperative contrast-enhanced CT angiography (CTA) scans for procedural planning, 4 male and 2 female, average age 64 years (range 52 to 73 years). All the CTA data were processed with FitMe 3D image processing software to get the modified 3D reconstruction pictures and computer language that can be identified by the 3D printer. With the fused deposition modeling technology, the highly accurate models were got to make preoperative endovascular planning. RESULTS: All the @entity1 ' models were printed before operations. By the guidance of models, the endovascular procedure plans were drawn up. Three @entity1 were performed extracorporeal simulating operations with the models and four @entity1 ' endovascular operations were guided by the models during the intraoperative time. The procedure technique success rate was 100%. No serious complications and @entity1 dead during the perioperative period. CONCLUSION: The technology of 3D printed highly accurate models of @entity449 models is feasible and can help to make preoperative endovascular planning for improving the safety of complicated procedures.
