Objective To evaluate the feasibility and security of endovascular repair of abdominal aorta using branched stent graft in a novel in vitro vascular model. Methods The branched stent graft for the abdominal aorta was designed. The novel in vitro vascular model was established to test this stent graft. Attempts were made to optimize the procedure of stent graft and to evaluate the feasibility of this device. The branched stent graft for abdominal aorta was tested by a novel in vitro vascular model. The number of stent graft released and expanded was recorded respectively. The pressure and situation of branch vessels were assessed before and after stent graft released. The endoleak during releasing process was observed by digital subtraction angiography (DSA). Results The stent graft was successfully deployed in the novel in vitro vascular model. The releasing process was all properly achieved (100%, 30/30). The pressure changes of branch vessels were no statistical significances (P > 0.05) between before and after stent graft released. The stent grafts were well landed, and were fully expanded and properly positioned by DSA. No endoleak occurred. Conclusion The branched stent graft for abdominal aorta in a novel in vitro vascular model is safe and feasible.
