Abstract

The present invention relates to aortic arch three collateral support blood vessels comprising an aorta support vascular that comprises an aorta ascenden section, an aortic arch section and an aorta section; the aorta support vascular also comprises three collateral artery support vasculars which are fixed respectively on an aortic arch section arc surface of the aorta support vascular and are formed into an five-way type. The three collateral artery support vasculars are corresponding respectively to an arteria anonyma, a left common carotid artery and a left subclavian artery. The invention is capable of greatly simplifying an operation process and greatly shortens the time of a deep hypothermia and a circulation arrest, which is characterized by not only omitting an inosculation between an artificial vascular graft and three branches of the aortic arch but also reducing bleeding rate and operation risk. In an operation, the invention changes an operation method from a partial blood vessel replacement plus partial endovascular repair to a complete endovascular repair.
