Objective To describe 3-dimensional (3D) printing of abdominal aortic aneurysms (AAA) with angulation neck anatomy to facilitate endovascular aneurysm repair (EVAR).Methods A 63-year-old male with AAA underwent preoperative contrast-enhanced CT angiography(CTA) scans.All the CTA data with DICOM style were collected, and imported into 3D reconstruction software.The 3D reconstruction image of infrarenal abdominal aortic was created.The 3D image data with STL style was identified and the AAA model was obtained by the 3 D printer.Finally, the EVAR planning was selected based on the 3D image and printing model.Results The AAA disease had a sharp neck angulation of 90°(αand β angels were 90°).The CTA images only indicated the conventional anatomy parameters.The 3D AAA disease with soft material was obtained by 3D printer.This model showed the following advantages to compare with CTA image: 1) the AAA disease was "drawn out" from the patient abdominal cavity; 2) the no-blind relations between the renal arteries ostial origins and angulation aneurysm neck; 3) the stress-strain simulating between a stent-graft and the angulation neck.4) the endovascular operation guiding during the intraoperative time.The EVAR was successfully performed following the 3D model and images.Conclusion 3D printed technology of abdominal aortic aneurysms is feasible and can aid decision making of EVAR.Based on the experience, we suggested that the more complex anatomy of AAA should be more benefited from this procedure.
