“…Presently, the major use of Three-Dimensional printing(3DP) in vascular surgery as reported by literature is offering visual and tactile support for pre-operative planning, although other anecdotal applications are described as well, namely guiding fenestration of endografts and simulating complex endovascular procedures [ 5 ]. Research of Tang F et al [ 6 ] demonstrated that it was feasible to rapidly design and manufacture a customized aortic stent graft assisted by 3DP technology, which showed improved geometric compliance and physical characteristics than the straight stent graft. These great advances in Three-Dimensional printing will indefinitely promote endovascular repair for patients with congenital arch anomaly.…”

Background Double aortic arch (DAA) combined with descending aortic arch dissection (DAAD) in adults is a rare aorta vascular disease. Due to the abnormal anatomy of the double arch and arch vessels, the clinical symptoms and surgical methods differ from those of typical aortic dissection. Methods This study was retrospective analysis of a case series involving three patients (mean age, 47.3 years) with DAA combined DAAD underwent total arch replacement or hybrid aortic repair from September 2010 to June 2019. The patients’ demographics, initial symptoms, comorbidities, surgical procedures, and outcomes are summarized. Results Total arch replacement plus frozen stent implantation under deep hypothermic circulatory arrest was performed for 2 patients, one of them developed disseminated intravascular coagulation and multiple organ failure postoperatively. Case 3 underwent a hybrid procedure with left subclavian artery revascularization and thoracic endovascular aortic repair. The symptoms of hoarseness and dysphagia were obviously improved during the follow up. Conclusion In addition to typical sudden chest and back pain, patients with DAA and DAAD may have hoarseness and dysphagia. Based on the development of DAA, total arch replacement or hybrid surgery may be is an optional treatment.

“…Surgeons can apply the detailed anatomical information provided by 3D models to solve critical problems. Surgeons can also use 3D models to accurately determine the location of a pseudoaneurysm lumen and whether an aneurysm entrance may be covered by a stent during thoracic endovascular aortic repair [40][41][42][43]. 3DP software can also facilitate stent sizing.…”

Three-dimensional printing (3DP) is an evolving technology with a wide range of medical applications. It complements the traditional methods of visualizing the cardiovascular anatomy and assists in clinical decision making, especially in the planning and simulation of percutaneous surgical procedures. The doctor–patient relationship has changed substantially, and patients have become increasingly aware of their rights and proactively make decisions regarding their treatment. We present our experience in using 3DP for aortic repair, preoperative surgical decision making for congenital heart disease, and simulation-based training for junior vascular surgeons. 3DP can revolutionize individualized treatment, especially for congenital heart disease, which involves unique anatomy that is difficult to examine using traditional computed tomography. As cardiovascular medicine and surgery require increasingly complex interventions, 3DP is becoming an essential technology for surgical instructors and trainees, who can learn to become responsible and humane medical doctors. 3DP will play an increasingly crucial role in the future training of surgeons.

“…However, currently available branched stent grafts remain severely limited in their anatomic suitability for most forms of aortic arch disease (6). Alternatively, utilizing three dimensional-printed, customized stent graft formulations and leveraging computational modeling techniques (e.g., fluid-structure interaction) may provide a means for "custom fit" stent grafts that could further mitigate and potentially alleviate many conformational limitations (7,8).…”
