The invention discloses an iron-base alloy vertebral artery degradable stent, relates to the technical field of blood vessel stents and in particular discloses the iron-base alloy vertebral artery degradable stent which comprises a base layer, wherein a framework layer is arranged inside the base layer; the shape of the base layer is of a spiral structure; a medicine layer is fixedly connected with the outer surface of the base layer; and a collagen layer is fixedly connected with the outer surface of the medicine layer. By adopting the iron-base alloy vertebral artery degradable stent, the framework layer is made of an iron-based alloy, so that the stent has an effect of good support performance; due to threaded cooperation of the framework layer, the stent is capable of enduring pressureof an artery blood vessel without deformation in the use process, so that a function of improving the blood vessel durability is achieved, and the purpose of preventing the stent from deformation isachieved; and due to arrangement of a threaded framework, the stent can be easy to bend, can be used at a bent part of the artery blood vessel and thus has the advantage of being wide in application range.
