The invention relates to a degradable intravascular stent and a preparation method thereof, and belongs to the technical field of medical instruments. The intravascular stent comprises an inner layer and an outer layer, a plurality of first grooves are formed in the inner layer, and the first groove layers are distributed in a grid shape; the outer layer is provided with a plurality of second grooves, the second grooves are distributed at intervals in the length direction of the intravascular stent, the second grooves are in a groove shape, and the second grooves are annularly formed in the outer layer around the central axis of the intravascular stent; the inner layer is provided with the first grooves which are distributed in a latticed manner, so that migration, adhesion and proliferation of endothelial cells can be specifically regulated and controlled, and endothelialization can be quickly completed. Meanwhile, the groove-shaped second grooves distributed at intervals in the length ...
