The invention discloses an abdominal aorta stent. The abdominal aorta stent comprises a bare stent, a film-covered stent main body, a first film-covered branch support and a second film-covered branch stent, wherein a fixing piece which is used for fixing the bare stent on an arterial wall is arranged on the bare stent; one end of the film-covered stent main body is connected with the bare stent; the first film-covered branch support and the second film-covered branch stent are connected with the other end of the film-covered stent main body, the diameter of the first film-covered branch support and the second film-covered branch stent is smaller than the diameter of the film-covered stent main body and the length of the first film-covered branch stent is greater than the length of the second film-covered branch stent; the film-covered stent main body, the first film-covered branch support and the second film-covered branch stent respectively comprise a plurality of stent bodies and high-molecular films which cover the plurality of stent bodies, and any two adjacent stent bodies are connected through the high-molecular films; the stent bodies and the bare stent are cylindrical structures which are formed by surrounding elastic wavy supporting bodies which can retract along the radial direction. Through the arrangement, the abdominal aorta stent provided by the invention has the advantages that the operating difficulty during conveying of the stent main body for an abdominal aorta tumor can be reduced and a larger wound caused to an aorta can be effectively reduced.
