    Introduction: The accuracy of fenestrations in stent-grafts for complex aortic aneurysms and dissections can be significantly improved using 3D printed phantoms. Standardization is enhanced by using artificial intelligence (AI) for image pre-processing prior to 3D printing. These methods address fallacies in centerline image analysis and manual image pre-processing. This review examines the application of 3D printing and AI in complex aortic aneurysm repair, highlighting current clinical trends.Methods: An exhaustive literature review was performed using keywords like "3D printing", "Artificial intelligence", "Thoracoabdominal aneurysm", "Abdominal aortic aneurysm", "Aortic arch aneurysm", "Endovascular repair", "Open repair" in PubMed and Google Scholar indexes up to June 2022.Results: This analysis included seven studies: four focused on 3D printed phantoms for endovascular repair of various aortic pathologies (aortic arch, thoracoabdominal aorta, juxtarenal and pararenal aorta), one on open thoracoabdominal aneurysm (TAAA) repair using 3D printed models for graft construction, and two on the use of convolutional neural networks (CNN), an AI based technology, for pre-processing of aortic computed tomography angiography (CTA) images.The application of 3D printing and AI-based image pre-processing in planning of complex aortic aneurysm offers several benefits, including enhanced patient and trainee education, more accurate fenestration placement, reduced surgical time and complications, and decreased surgeon stress.
