Problems solved by technology

In recent years, with the emergence of clinical three-branch artificial vascular stents, for example: the new three-branch aortic arch endovascular stent graft introduced in the Journal of Central South University in 2012 in DeBakey type l aortic dissection. Although the application of the three-branch artificial stent-graft has solved the difficulty and damage of artificial blood vessel replacement in the aortic arch to a certain extent, the position of the thr

Embodiment Construction

[0013] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below in conjunction with the embodiments.

[0014] see figure 1 with figure 2 , Stanford type A aortic dissection artificial vascular stent, which includes a stent main body 100, and a single or two branches 102 are fixed at the proximal end of the stent main body 100. The stent artificial blood vessel is glued on the nickel-titanium alloy metal skeleton.

[0015] For the single-branch artificial vascular stent, a single branch is fixed about 2cm away from the opening of the proximal end of the main body of the stent. The internal diameter of the left subclavian artery 500 is stretched, and the endovascular repair of the descending aorta and the left subclavian artery 500 is completed, and the proximal end of the stent is anastomosed with the artificial blood vessel.

[0016] For the two-branch stent, two branches are fixed at a position about 2...

Abstract

The invention discloses a blood vessel prosthesis stent for Stanford type A aortic dissection. The blood vessel prosthesis stent comprises a main stent body, wherein a single branch or two branches is or are fixed at a proximal end of the main stent body. With the adoption of the blood vessel prosthesis stent, the amount of vascular anastomosis of a patient with Stanford type A aortic dissection affecting the aortic arch part can be effectively reduced, the surgical procedures are simplified, the risk of hemorrhage is reduced, deep hypothermic circulatory arrest and low-flow cerebral protection time in the period of cardiovascular arrest are shortened, so that the surgical treatment effect of the patient with the Stanford type A aortic dissection is improved, and the blood vessel prosthesis stent can be popularized in primary hospitals.

Description

technical field [0001] The invention relates to the field of aortic dissection artificial vascular stent, in particular to a Stanford type A aortic dissection artificial vascular stent involving the aortic arch. Background technique [0002] Aortic dissection is a critical disease in cardiac surgery with acute onset, short course and poor prognosis. Among them, Stanford type A aortic dissection has the highest incidence rate, and the fatality rate without surgical treatment is as high as 70%, and surgical operations are often required. Because Stanford type A aortic dissection often involves the aortic arch, the surgical treatment of Stanford type A aortic dissection involving the aortic arch has long been a key issue in aortic surgery research. At present, the most commonly used clinical surgical treatment method is the "Sun's operation" introduced in "Aortic Arch Replacement and Stent "Elephant Trunk" Surgery for Stanford Type A Aortic Dissection" published in the Chinese...
