Objective: To investigate the feasibility for reconstructing an aortic arch by a new integrated two-branched stent graft releasing in experimental canine thoracic aorta simulation system. Methods: A new type of integrated two-branched stent graft was developed and placed in the canine thoracic aorta, the stent graft releasing in a simulated system was conducted under X-ray guidance to monitor the operating process and to explore the feasibility for invitro sent graft releasing. Results: The new two-branched stent graft was successfully deployed in canine thoracic aorta simulation system. The releasing process was smooth, two small stent grafts were well landing, and all stent grafts were fully expanded and properly positioned. Conclusion: Our new two-branched stent graft could successfully reconstruct the aortic arch in experimental canine. The thoracic aorta releasing system may better and truly simulate the whole process of endovascular aortic repairing, which provides a good foundation for further animal experiments.
