A vascular stent, including a plurality of wave-shaped supporters connected in an axial direction. The tubular stent includes a proximal support mechanism, a middle support mechanism, and a differential support mechanism connected in sequence; the middle support mechanism and the distal support mechanism are respectively closed-loop structure; the proximal support mechanism includes a first support portion connected to the middle support mechanism and a second support portion provided at the proximal end of the first support portion; the first support portion is a closed-loop structure; the second support portion is an open-loop structure, and the end surface of the proximal end of the second support portion is an uneven structure to provide local support in the circumferential direction.
