(AFP) The reference news network reported on November 4 that the foreign media said that the National Center for Circulatory Disease Research announced that the center's researchers have successfully developed artificial blood vessels with a diameter of only 0.6 mm. This is the world's finest artificial blood vessel and is expected to be used in the field of vascular bypass surgery for the brain and heart. At present, the finest artificial blood vessels are about 3 mm in diameter, and the finer blood vessels need to be obtained and transplanted from other parts of the patient's own body, but it is often difficult to obtain blood vessels of a specific length and shape. According to the Singapore Lianhe Zaobao website reported on November 4, at present, when the blood vessels in the human body rupture, the artificial blood vessels of the polyester material can be transplanted, but since the blood is easily coagulated on the inner wall of the artificial blood vessel, if the artificial blood vessel is too thin, it is easy to block. This has always been a difficulty in developing artificial blood vessels. A research team at the center used collagen to coat the foreign body entering the body, and wrapped the stainless steel wire covered with silicon with a diameter of 0.6 mm and a length of 2 cm into the back of the rat for about two months. After taking it out, it was found that a collagen tube was formed around the stainless steel wire. After transplanting the tube into the thigh of the experimental mouse, the researchers observed it for about six months and found that it played the role of artificial blood vessels. According to the report, the research team is preparing to conduct clinical research within one or two years and to popularize it five years later. At that time, the artificial blood vessel is expected to be used for transplantation operations such as the brain and the heart that require very fine blood vessels.
