血管并发症是经导管主动脉瓣植入术受到制约的主要并发症，与经导管主动脉瓣植入术后出血、输血及病死率密切相关。由于经股动脉经导管主动脉瓣植入术创伤最小，因此成为经导管主动脉瓣植入术的首选手术路径。新一代大鞘管及无鞘管技术的应用，不但使得那些存在外周血管病的患者成功实施经导管主动脉瓣植入术，而且使血管并发症显著降低。“,”Vascular complications are a potential limitation of transcatheter aortic valve implantation ( TAVI) and have been associated with bleeding ,transfusions and mortality .Transfemoral TAVI can be considered the least invasive approach and is therefore the most widely used access for TAVI .The use of new generation sheath and sheathless technique not only increases access -site availability in patients with peripheral artery disease ,but also reduces vascular complications significantly .
