Rapid-prototyping of the aorta – 3D-printing of individual vessel structure for endovascular 3D-navigation–Presented by Prof. Dr. med. Markus Kleemann, University Medical Center Schleswig-Holstein-Campus Lübeck at the 3D Med tech Printing Conference, which takes place on Feb 01 2017 at MECC Maastricht in The Netherlands.
Endovascular Aortic Repair (EVAR) shows medical benefits compared to open surgery. Implementation of 3D-navigation in EVAR should reduce contrast medium and radiation dose of the procedure (Nav-CARS EVAR).
First step is made by segmentation on the basis of CT-angiogram of a patient with abdominal aortic aneurysm. Second, the patient-specific aortic model is manufactured by rapid prototyping using the „poly jet technology“(3D-printing). In this technique, multiple layers of a photopolymer (acrylic resin) are successively added and the desired model shape is cured by UV light. As a 3rd step follows the post-processing of the aortic model which means the removal of the support material in multiple steps (manually, sodium hydroxide, water quench). The placement of aortic stents into the produced realistic vascular model is then simulated under fluoroscopy in the last step.
Rapid Prototyping of the abdominal aorta allows experimental investigations on the 3D navigation of EVAR. The experience of system integration and measurements for accuracy are essential to further development of endovascular 3D navigation
