Blood vessel stent device

The invention relates to a blood vessel stent device and use methods thereof. The caliber of the front half section of the blood vessel stent device can be equal to the caliber of the rear half section of the blood vessel stent device, or the caliber of the front half section of the blood vessel stent device can be larger than or less than the caliber of the rear half section of the blood vessel stent device, so as to adapt to blood vessels of different size of a receptor. The use methods of the blood vessel stent mainly comprise two use methods, i.e. an end-to-end anastomosis method and an end-to-side anastomosis method, wherein an end-to-end part is that a guide wire is put in a receptor blood vessel which is to be used as a anastomosis blood vessel, the other section of blood vessel tobe anastomosed is sheathed on the guide wire, and the blood vessel stent for anastomosis is slid into the receptor blood vessel along the guide wire. The strip label of the blood vessel stent can be directly seen from a trans
