| Popis: | The artificial blood vessel of 5mm I. D. compound-braided by using two ply yarns of polytetrafluoroethylene and collagen is designed and manufactured by circular braider.The test tubes of about 50mm in length were implanted in the place of the right external iliac artery in line and in the right common carotid artery as an arteriovenous shunt to the right external jugular vein of an adult mongrel dog. Microknit tubes of 4mm I. D. and 50mm in length, polyester knitted vascular prostheses of Golaski Lab., Philadelphia, Pa., U.S.A., were implanted in the left side respectively as a control.Bleeding through the tubes at implantation was found less in the new designed tubes than in the Microknits. The specimen obtained two days after implantation showed; 1) test tube implanted in the right external iliac artery was found thrombosed at the sites of anastomoses, and 2) the other one implanted in the right common carotid artery was found free from thrombus formation, whereas no thrombus formation in the Microknit grafts either in the external iliac or in the common carotid arteries.Poor cuff formation and too much tension of the tube at implantation should be responsible for an early thrombus formation. |
