Abstract
Objective: This study evaluates the effectiveness and applicability of PMSGs created from 3D-printed models in managing aortic disease. Background: Endovascular treatment of aortic disease can be challenging, especially with complex anatomy. Three-dimensional (3D) printed models, derived from computed tomography (CT) and magnetic resonance imaging (MRI) scans, have been used to create physician-modified stent grafts (PMSGs) for vascular procedures involving the aorta. Methods: A systematic search was conducted in July 2024 across Embase, Ovid Medline, and Web of Science using PRISMA guidelines. Keywords included “aorta”, “3-dimensional printing”, and “implant”. Only studies reporting use of 3D printing-assisted PMSGs in aortic disease repair, experimental trials, and written in English were included. Outcomes evaluated were 30-day mortality, endoleaks, and adverse neurological events. Results: 435 patients treated with PMSGs were analyzed: 344 for descending aorta, 85 for aortic arch, 4 for ascending aorta, and 2 for multiple segments. Common pathologies included aortic dissection (279 patients) and aortic aneurysm (153 patients). The mean follow-up was 9.2 months. The overall 30-day mortality was 2.2%, endoleaks occurred in 6.4%, and neurological complications in 3.4%. Higher endoleak rates were observed in ascending aorta dissection (33%) compared to descending (6.2%). Mortality (5.9%), endoleaks (9.7%), and neurological complications (4.4%) were higher in descending aortic aneurysms compared to dissections. Conclusion: PMSGs derived from 3D printed models provide a minimally invasive option for treating complex aortic diseases. Outcomes are comparable to traditional methods, but further studies are needed to assess long-term results. Grants: No funding was received for this study.
