Abstract    Branched stent-graft technique is more suitable for endovascular treatment of aortic aneurysms or dissection involving the aortic arch，with more in line with normal anatomical structure and lots of researches have been done all over the world. In China，there are head attached branched stent-graft and bifurcated spliced branched stent-graft. But clinical trials of them failed due to design defects and release methods problem. Japanese Inoue integrated branched stent-graft either failed. Other overseas including Cook's "inner chimney" branched stent-graft，Bolton Medical's large window inner chimney branched stent-graft，Gore's inner periscope branched stent-graft，Medtronic's protruding window connecting branched stent-graft are undergoing clinical trials，but none has been approved by the public. Castor branched stent-graft is the first branched stent-graft approved by the state in the world. It can be used as a commercial branched stent-graft. It was jointly developed by Department of Vascular Surgery, Shanghai Changhai Hospital and Shanghai MicroPort Company. The integrated design of the stent and the safety and precision design of the delivery and release system make it obtain good clinical application results. However，Castor branched stent-graft is a single branched stent-graft，its application still has some limitations，to completely solve the aortic arch lesions still need further research. The combination of various technologies may be the direction of endovascular repair of aortic arch lesions in the next 5 years.
