Problems solved by technology

The operation is cumbersome and complicated, and it takes a long time
Due to the large number of anastomoses between artificial grafts and autologous blood vessels, there is a greater chance of bleeding, and the mortality and complications of surgery are higher, and the risk is greater

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] As shown in Figure 1, the aortic arch three-side branch stent vessel involved in the present invention includes an aortic stent vessel 1, and the aortic stent vessel 1 is divided into an ascending aortic segment 7, an aortic arch segment 6 and a descending aortic segment 5 , it also includes three collateral artery stent vessels 2, the three collateral artery stent vessels 2 are respectively fixed on the arc surface of the aortic arch segment 6 of the aortic stent vessel 1, and form a five-way type, the three The collateral artery stent vessels 2 respectively correspond to the innominate artery 8 , the left common carotid artery 9 and the left subclavian artery 10 on the aortic arch 11 respectively.

[0021] The diameter of the aortic stent vessel 1 is 20-40 mm, and the diameter of the three side branch arterial stent vessels 2 is 5-18 mm.

[0022] The covering...

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.

Description

technical field [0001] The invention relates to a stent vessel, in particular to a stent vessel with three side branches of the aortic arch. Background technique [0002] In the prior art, for diseases involving the aortic arch, such as aortic dissection, aortic arch pseudoaneurysm, total thoracic aortic dilatation, etc., the treatment method is mostly ascending aorta, aortic arch replacement plus stent elephant trunk surgery, the operation is complicated The degree and risk are relatively large, and artificial blood vessels with side branches and stent blood vessels need to be used during the operation. Usually, the right axillary artery cannula is used for perfusion, and cardiopulmonary bypass is performed. Under deep hypothermia and circulatory arrest, the ascending aorta, part or all of the aortic arch are resected, the stent is released into the descending aorta, and the proximal end of the stent and the side branch are completed. Artificial blood vessel and aortic ana...
