The locating section (1) comprises a plurality of first repeating units (11); the supporting section (2) comprises at least two supporting elements (21) and at least one connecting element (22), the supporting element (21) comprising a plurality of second repeating units (211), the number of the first repeating units (11) being different from that of the second repeating units (211); a plane formed by the front end portions of the plurality of first repeating units (11) is vertical to or intersects with the axis of the vascular stent. The vascular stent is especially suitable for iliac veins, has a good support effect for iliac veins and small damage to venous walls, and can effectively prevent the formation of secondary thrombus within the vascular stent after it is implanted.
