Problems solved by technology

[0003] During the operation, the "artificial aortic valve + artificial blood vessel" type of pipeline is widely used. During the operation, there will be bleeding and oozing at the suture of the artificial aortic valve, accompanied by the appearance of the artificial aortic valve suture. Bleeding and oozing will reduce the success rate of the entire operation

Abstract

The invention discloses an artificial vascular conduit with a hemline and a suturing method thereof. The artificial vascular conduit with the hemline comprises an artificial blood vessel; a connectingend of the artificial blood vessel is connected with an artificial valve; a suture ring is connected to the outside of the end of the artificial valve which is connected with the artificial blood vessel; and a hemline is connected with an outer ring surface of the suture ring. The artificial vascular conduit with the hemline disclosed by the invention is a combination of the artificial blood vessel, the artificial valve, the suture ring and the hemline. In the process of using, when the artificial vascular conduit with the hemline is being sutured with an aortic annulus, the artificial vascular conduit is capable of reducing the risk of bleeding and oozing of blood along the suture line of the suture ring and the aortic annulus, thereby facilitating improvement of success rate of a wholeoperation; and moreover, the whole suturing process is easy and convenient to operate, and performance of the suture operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of cardiac surgery, in particular to a skirted artificial blood vessel and a suturing method. Background technique [0002] Bentall operation is one of the common great vessel operations in cardiac surgery. Bentall operation, also known as "ascending aortic replacement with aortic valve artificial vessel", is a surgical method for the treatment of ascending aortic aneurysm, and is suitable for ascending aortic dissection. Involving the coronary sinus or complicated by aortic valve insufficiency, the method is to free the ascending aorta, resect the diseased segment of the ascending aorta, retain its rear and left and right coronary artery openings, resect the aortic valve, and transplant artificial blood vessels with valves. The artificial valve is intermittently sutured on the annulus, and the spacers are often exposed and stagnant outside the annulus. Then the left and right coronary arteries are transplan...
