A blood conduit with stent has a flexible conduit body and an expandable stent structure. The conduit body has a first opening end through which only an inflow of a blood enters and a second opening end through which only an outflow of the blood leaves. The stent structure includes a plurality of threads adhered to the conduit body and expands in directions intersecting an axial direction of the conduit body. A boundary of one of the threads of the stent structure closest to the second opening end is away from the second opening end with a predetermined distance, thereby preventing blood back flow into the false lumen via a new tear.
